| Product Family | Catalog/Series | Lifecycle Status | Discontinuation or milestone date | Recommended Replacement / Migration Path | Migration Conditions |
|---|---|---|---|---|---|
| MELSEC-A / QnA programmable controllers (large type) | A/QnA large-type CPU, I/O, special function and data link modules | Production discontinued (Mitsubishi MELSEC-A/QnA Series Transition Guide, L08077E) | CPU, I/O, special function and data link modules: production discontinued end of September 2006; MELSECNET/MINI-S3 master module: end of September 2008; MELSECNET/10 network module: end of September 2014 (bulletin FA-A-0141) | MELSEC-Q series per the transition guide; Mitsubishi's current published direction for the MELSEC-A series is MELSEC iQ-R (see the A61PN/A61RP record, FA-A-0365-A) | Repair/service availability runs seven years from each discontinuation (per bulletin FA-A-0049). A/QnA→Q conversion adapters and base adapters reuse existing wiring and the A/QnA base unit's installation holes (US MELSEC-A Series Transition page); the Q series large-type I/O module is 14 mm deeper than the A series 32-point module — check panel depth |
| MELSEC A2C programmable controllers | A2C CPU, I/O and special function modules | Production discontinued (Transition Guide L08077E) | CPU module: end of September 2006; I/O and special function modules: end of September 2008 | MELSEC-Q / MELSEC iQ-R platform; for the MELSECNET/MINI-S3 network, Mitsubishi documents A2C-shape CC-Link remote I/O modules as the replacement path (US MELSEC-A Series Transition page) | The A2C-shape CC-Link remote I/O module has the same installation size as A2C I/O modules — the existing terminal block can be installed directly (US transition page) |
| MELSEC A0J2(H) programmable controllers | A0J2(H) series | Production discontinued (Transition Guide L08077E) | End of September 2008 | MELSEC-Q / MELSEC iQ-R platform per the A/QnA transition guidance | See migration notes (MELSEC-A/QnA) |
| MELSEC-AnS / QnAS programmable controllers (small type) | AnS/QnAS small-type CPU and modules | Production discontinued (MELSEC-AnS/QnAS (Small Type) Series Transition Guide, L08236E) | Production discontinued end of September 2014; end of service September 2021 (seven-year service availability period) | MELSEC-Q series per the transition guide; current platform direction is MELSEC iQ-R | AnS/QnAS→Q conversion adapters reuse the existing wiring of I/O, analog, high-speed counter and temperature modules, and base adapters reuse the AnS/QnAS installation holes (US MELSEC-A Series Transition page) |
| MELSEC-A power supply modules | A61PN, A61RP | Production discontinuation announced (Technical Bulletin FA-A-0365-A) | Transition to make-to-order: March 31, 2022; order acceptance: until November 28, 2025; production discontinuation: December 31, 2025; repair support: until December 31, 2032 | MELSEC iQ-R series — the bulletin states the MELSEC-A series has already been discontinued and its repair acceptance period has expired, and directs replacement with MELSEC iQ-R | Migration reference: "Transition from MELSEC-A/QnA (Large Type) Series to MELSEC iQ-R Series Handbook" (L08666ENG), named in the bulletin |
| MELSEC-Q programmable controllers (legacy CPU models) | High Performance model QCPU (Q02CPU, Q02HCPU, Q06HCPU, Q12HCPU, Q25HCPU), Basic model QCPU (Q00JCPU, Q00CPU, Q01CPU), QCPU-A (A mode), QA1S main base units | Production discontinued (Technical Bulletin FA-A-0223-B) | Transition to make-to-order: June 30, 2017; order acceptance: through August 31, 2018; production discontinuation: September 30, 2018; repair support: until September 30, 2025 | High Performance QCPU → Highspeed Universal model QCPU (Q02CPU/Q02HCPU→Q03UDVCPU, Q06HCPU→Q06UDVCPU, Q12HCPU→Q13UDVCPU, Q25HCPU→Q26UDVCPU); Basic QCPU → Universal model QCPU (Q00JCPU→Q00UJCPU, Q00CPU→Q00UCPU, Q01CPU→Q01UCPU); QA1S base units → Q base units (e.g. QA1S33B→Q33B) | USB connector type changes (miniB) — cable replacement or a conversion adapter is required (bulletin FA-A-0036); if the file register file is stored on an SRAM/Flash card, an extended SRAM cassette is required on the QnUDVCPU; replacing a QA1S base unit requires panel redesign |
| MELSEC-Q Universal model QCPU (selected models) | Q03UDCPU, Q03UDECPU, Q04UDHCPU, Q04UDEHCPU, Q06UDHCPU, Q06UDEHCPU, Q10UDHCPU, Q10UDEHCPU, Q13UDHCPU, Q13UDEHCPU, Q20UDHCPU, Q20UDEHCPU, Q26UDHCPU, Q26UDEHCPU | Production discontinuation announced (Technical Bulletin FA-A-0418-A) — order acceptance closed September 30, 2026 | Order acceptance: until September 30, 2026; production discontinuation: October 30, 2026; repair support: until October 31, 2033 | Highspeed Universal model QCPU (Q03UD→Q03UDVCPU, Q04UDH→Q04UDVCPU, Q06UDH→Q06UDVCPU, Q10UDH/Q13UDH→Q13UDVCPU, Q20UDH/Q26UDH→Q26UDVCPU) or MELSEC iQ-R CPU (→R04CPU / R08CPU / R16CPU / R32CPU per the bulletin's replacement table) | The bulletin publishes separate replacement guidance for the QnUDVCPU path (page 3) and the MELSEC iQ-R path (page 5) — the iQ-R path is a platform change, the QnUDVCPU path stays within MELSEC-Q |
| MELSEC-Q C Controller modules | Q12DCCPU-V, Q24DHCCPU-V, Q24DHCCPU-LS, Q26DHCCPU-LS and related set products / software | Production discontinuation announced (Technical Bulletin FA-A-0446-A) | Transition to make-to-order: March 31, 2025; order acceptance: through February 28, 2030; production discontinuation: March 29, 2030; repair support: until March 31, 2037 | MELSEC iQ-R: Q12DCCPU-V→R12CCPU-V; Q24DHCCPU-V→R12CCPU-V or RD55UP12-V; Q24DHCCPU-LS→RD55UP06-V or RD55UP12-V | Specification/function differences are documented in the "MELSEC-Q Series to MELSEC iQ-R Series Migration Guide" (L08510ENG), named in the bulletin |

How do I check whether a specific Mitsubishi Electric Automation part is in this dataset?
Open the free sample records on the dataset page first — they are copied verbatim from the paid file. The full file lists every record with its source notice, so you can confirm coverage of your exact part number before relying on the cross-reference.
What does last time buy (LTB) mean?
The last date the manufacturer accepts orders for a discontinued part. After it passes, the part is only available from remaining distributor stock or the secondary market — which is exactly when a verified replacement cross-reference matters most.
Are the recommended replacements drop-in compatible?
Not necessarily. Manufacturers' own notices sometimes warn that a recommended replacement is not pin or voltage compatible and requires a board redesign. Where the source notice prints such a warning, it is carried in the dataset — always check the replacement's package and key specs against your design.
Where does this data come from?
Every record is extracted from a Mitsubishi Electric Automation document — the manufacturer's own lifecycle, discontinuation, PCN/PDN notices and the affected-part lists they publish — downloaded from the manufacturer's own channels. No part number, date or replacement is inferred; if the manufacturer did not print it, it is not in the file.
