Substitute Part Grouping Explanation

Substitution of the PIC16CE623-20E/P is determined by strict alignment of the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating frequency (20MHz)
• Program memory capacity and type (896B OTP)
• EEPROM and RAM configuration (128 x 8 and 96 x 8 respectively)
• I/O pin count (13)
• Supply voltage range (3V ~ 5.5V)
• Physical package (18-DIP)
• Peripheral feature set (Brown-out Detect/Reset, POR, WDT)

The PIC16CE623-20I/P qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is the operating temperature range and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16CE623-20I/P is a valid substitute for the PIC16CE623-20E/P based on electrical and functional equivalence. The primary consideration is the operating temperature range: the main part supports -40°C to 125°C, while the substitute supports -40°C to 85°C. Applications requiring operation above 85°C must retain the original PIC16CE623-20E/P specification.

The substitute part carries Active product status, ensuring continued availability and manufacturing support, whereas the main part is classified as Obsolete. Both parts maintain ROHS3 compliance and identical peripheral configurations. Selection should be based on specific application temperature requirements and availability constraints.

Frequently Asked Questions (FAQ)

Q: Can PIC16CE623-20I/P replace PIC16CE623-20E/P in all applications?

A: Substitution is valid for applications operating within the -40°C to 85°C temperature range. Applications requiring operation above 85°C must use the original PIC16CE623-20E/P.

Q: Are the pin configurations identical between these parts?

A: Yes. Both parts use the 18-DIP package with 0.300" (7.62mm) spacing and identical pinout. No PCB modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The PIC16CE623-20E/P is classified as Obsolete, indicating discontinued manufacturing. The PIC16CE623-20I/P is Active, ensuring ongoing availability and manufacturing support for new procurements.

Q: Are memory specifications identical?

A: Yes. Both parts feature 896B program memory (512 x 14), 128 x 8 EEPROM, and 96 x 8 RAM with identical access characteristics.

Q: Do both parts support the same supply voltage range?

A: Yes. Both parts operate across 3V to 5.5V supply voltage range with identical electrical performance within this specification.
