Substitute Part Grouping Explanation

Substitution of the PIC16LCE624T-04E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor with identical instruction set compatibility
• Memory Configuration: 1.75KB OTP program memory, 128 x 8 EEPROM, 96 x 8 RAM
• Operational Specifications: 4MHz clock speed, 2.5V to 5.5V supply voltage range
• I/O Count: 13 I/O pins
• Peripheral Set: Brown-out detection, power-on reset, watchdog timer
• Package Format: 20-SSOP surface mount package with identical pinout
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The substitute part PIC16LCE624-04I/SS maintains full compatibility across all these parameters, with the primary distinction being the operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LCE624-04I/SS serves as a direct functional substitute for the obsolete PIC16LCE624T-04E/SS. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute part carries Active product status, ensuring continued availability and manufacturing support from Microchip Technology.

The primary operational difference is the maximum operating temperature specification: the main part supports -40°C to 125°C, while the substitute supports -40°C to 85°C. Component selection should account for this temperature range differential based on application requirements.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming equivalent environmental and handling characteristics. The 20-SSOP package format and pinout are identical, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can PIC16LCE624-04I/SS replace PIC16LCE624T-04E/SS in existing designs?

A: Yes. The substitute part maintains identical core architecture, memory configuration, I/O count, peripheral set, and package format. Direct substitution is supported at the board level without design modifications.

Q: What is the significance of the operating temperature range difference?

A: The main part operates to 125°C maximum, while the substitute operates to 85°C maximum. Applications requiring operation above 85°C ambient temperature must retain the original part specification or identify alternative solutions rated for extended temperature ranges.

Q: Are the package dimensions and pinout identical?

A: Yes. Both parts use the 20-SSOP package with 0.209" width and 5.30mm body dimension. Pinout is identical, confirming mechanical and electrical compatibility.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for both parts.

Q: Why is the main part classified as obsolete?

A: Microchip Technology has discontinued the PIC16LCE624T-04E/SS variant. The PIC16LCE624-04I/SS remains in active production, providing continued supply and support for this microcontroller architecture.
