Engineering Selection Recommendations

PIC16CE624-04E/SS is the primary substitute for the obsolete PIC16CE624T-04E/SS. Both parts maintain identical electrical specifications and temperature operating range (-40°C to 125°C). The PIC16CE624-04E/SS carries active product status from Microchip Technology and is verified as programmable through DiGi-Electronics channels. This part is available in tube packaging with 863 units in current stock inventory.

PIC16CE624-04I/SS serves as an alternative substitute with active product status. This part is functionally equivalent across all critical parameters with the exception of operating temperature range, which is limited to -40°C to 85°C. The PIC16CE624-04I/SS is verified as programmable and maintains higher inventory availability with 1023 units in stock. Selection of this part is appropriate for applications where the reduced upper temperature limit does not conflict with system requirements.

Both substitute parts are ROHS3 compliant and carry identical compliance certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.31.0001) as the original part.

Frequently Asked Questions (FAQ)

Q: Can PIC16CE624-04E/SS directly replace PIC16CE624T-04E/SS in existing designs?

A: Yes. The PIC16CE624-04E/SS maintains identical electrical specifications, memory configuration, I/O count, peripheral set, and package form factor. The primary difference is product status transition from obsolete to active.

Q: What is the difference between PIC16CE624-04E/SS and PIC16CE624-04I/SS?

A: Both parts are functionally equivalent with identical core specifications. The PIC16CE624-04I/SS has a reduced operating temperature range of -40°C to 85°C, compared to -40°C to 125°C for the PIC16CE624-04E/SS. Selection depends on application temperature requirements.

Q: Are the substitute parts pin-compatible with the original part?

A: Yes. All three parts use the 20-SSOP package with identical pinout and mechanical dimensions (0.209" width, 5.30mm).

Q: Do the substitute parts require any firmware modifications?

A: No. The substitute parts maintain identical instruction set architecture, memory organization, and peripheral functionality. Existing firmware compiled for the original part is compatible without modification.

Q: What is the packaging difference between the substitute parts?

A: PIC16CE624-04E/SS is supplied in tube packaging. PIC16CE624-04I/SS packaging type is not specified in available documentation. Confirm packaging requirements with supplier specifications for procurement planning.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both PIC16CE624-04E/SS and PIC16CE624-04I/SS are ROHS3 compliant with MSL Level 1 (unlimited moisture sensitivity).
