Substitute Part Grouping Explanation

Substitution eligibility for the PIC16CE623T-04E/SS is determined by strict equivalence across the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating frequency (4MHz)
• Program memory capacity and type (896B OTP)
• EEPROM and RAM configuration (128 x 8 and 96 x 8)
• I/O pin count (13)
• Supply voltage range (3V ~ 5.5V)
• Package type and physical dimensions (20-SSOP)
• Peripheral feature set (Brown-out Detect/Reset, POR, WDT)

The identified substitutes maintain full electrical and mechanical compatibility with the main part number across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

PIC16CE623-04E/SS is the primary substitute for the obsolete PIC16CE623T-04E/SS. Both parts maintain identical electrical specifications and operating temperature range (-40°C ~ 125°C). The PIC16CE623-04E/SS carries Active product status and verified programmability, ensuring long-term availability and production support.

PIC16CE623-04I/SS is a secondary substitute option. This part is functionally equivalent across all core parameters but operates within a reduced temperature range (-40°C ~ 85°C). Selection of this part requires confirmation that the application does not require operation above 85°C. Both substitute parts are ROHS3 compliant and carry MSL 1 rating, matching the compliance profile of the main part.

Frequently Asked Questions (FAQ)

Q: Can PIC16CE623-04E/SS directly replace PIC16CE623T-04E/SS in existing designs?

A: Yes. Both parts share identical electrical specifications, memory configuration, I/O count, supply voltage range, and 20-SSOP package dimensions. The primary difference is product status: PIC16CE623-04E/SS is active and available, while PIC16CE623T-04E/SS is obsolete.

Q: What is the difference between PIC16CE623-04E/SS and PIC16CE623-04I/SS?

A: The parts are electrically identical except for operating temperature range. PIC16CE623-04E/SS operates from -40°C to 125°C, while PIC16CE623-04I/SS operates from -40°C to 85°C. 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 physical dimensions (0.209", 5.30mm width) and pin configuration, ensuring direct PCB compatibility.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both PIC16CE623-04E/SS and PIC16CE623-04I/SS are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating, matching the compliance profile of PIC16CE623T-04E/SS.

Q: Which substitute should be selected for new production designs?

A: PIC16CE623-04E/SS is recommended for new designs. It maintains the full operating temperature range of the original part and carries active product status, ensuring long-term supply continuity.
