Key Parameters

Substitute Part Grouping Explanation

Substitution of the PIC16C620-20E/SS is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating frequency (20MHz)
• Program memory capacity and type (896B OTP)
• RAM capacity (80 x 8)
• I/O pin count (13)
• Supply voltage range (3V ~ 6V)
• Package type and dimensions (20-SSOP)
• Mounting configuration (Surface Mount)

The PIC16C620-20I/SS qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction lies in product status and operating temperature range, which do not affect functional compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C620-20I/SS is the direct substitute for the obsolete PIC16C620-20E/SS. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The PIC16C620-20I/SS carries active product status from Microchip Technology, providing ongoing availability and supply chain reliability.

The operating temperature range difference (-40°C ~ 85°C for the substitute versus -40°C ~ 125°C for the original) should be evaluated against application requirements. Applications operating within the -40°C ~ 85°C range experience no functional limitation. Applications requiring operation above 85°C must retain the original part or identify alternative architectures.

Both parts maintain ROHS3 compliance and identical moisture sensitivity levels, supporting equivalent environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the PIC16C620-20I/SS directly replace the PIC16C620-20E/SS?

A: Yes. Both parts share identical core processor architecture, memory configuration, I/O count, supply voltage range, frequency rating, and 20-SSOP package dimensions. Pin-for-pin and functional compatibility is confirmed.

Q: What is the difference between the -20E and -20I designations?

A: The designations reflect different product status and operating temperature specifications. The -20E variant is obsolete with a -40°C ~ 125°C operating range. The -20I variant is active with a -40°C ~ 85°C operating range. All other electrical and mechanical parameters are identical.

Q: Does the reduced operating temperature range of the PIC16C620-20I/SS affect compatibility?

A: Compatibility depends on application requirements. If your design operates within -40°C ~ 85°C, the PIC16C620-20I/SS provides full functional equivalence. Applications requiring operation above 85°C must use the original part or evaluate alternative microcontroller architectures.

Q: Are both parts RoHS compliant?

A: Yes. Both the PIC16C620-20E/SS and PIC16C620-20I/SS are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What package type is used for these parts?

A: Both parts use the 20-SSOP (Shrink Small Outline Package) with 0.209" width and 5.30mm dimensions, suitable for surface mount assembly.
