Key Parameters

Substitute Part Grouping Explanation

Substitution for the PIC16C620T-04E/SS is determined by strict equivalence across the following critical parameters:

• Core Processor Architecture: PIC 8-bit processor
• Program Memory Configuration: 896B (512 x 14) OTP
• RAM Configuration: 80 x 8 bytes
• I/O Pin Count: 13 pins
• Operating Voltage Range: 3V ~ 6V
• Package Type: 20-SSOP surface mount
• Peripheral Set: Brown-out Detect/Reset, POR, WDT

The identified substitute parts maintain identical electrical and mechanical specifications within these parameters. Differences in product status (active vs. obsolete) and operating temperature ranges are noted but do not affect functional substitutability for applications within the specified temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

PIC16C620-04E/SS is the primary substitute for the obsolete PIC16C620T-04E/SS. Both parts share identical electrical specifications and operating temperature range (-40°C ~ 125°C). The PIC16C620-04E/SS maintains active product status with verified programmability and higher inventory availability (930 Pcs), making it the preferred choice for new designs and production continuity.

PIC16C620-04I/SS is a secondary substitute with identical core functionality and memory configuration. The operating temperature range is reduced to -40°C ~ 85°C, which limits its application to designs not requiring the extended upper temperature specification. This part is also actively produced with verified programmability and substantial inventory (958 Pcs).

Both substitute parts are ROHS3 compliant and carry identical compliance certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.31.0001) as the main part. Selection between PIC16C620-04E/SS and PIC16C620-04I/SS depends solely on application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can PIC16C620-04I/SS replace PIC16C620T-04E/SS in all applications?

A: PIC16C620-04I/SS is functionally equivalent for applications operating within -40°C to 85°C. Applications requiring operation above 85°C must use PIC16C620-04E/SS, which supports temperatures up to 125°C.

Q: Are the package dimensions identical across all three parts?

A: Yes. All three parts use the 20-SSOP package with identical dimensions (0.209", 5.30mm Width), ensuring mechanical compatibility in PCB layouts.

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

A: The PIC16C620T-04E/SS is classified as obsolete, indicating discontinued production. The substitute parts PIC16C620-04E/SS and PIC16C620-04I/SS are actively produced, ensuring long-term availability for production and design support.

Q: Are there differences in memory configuration between the substitute parts?

A: No. All three parts feature identical program memory (896B OTP), RAM (80 x 8), and I/O pin count (13). Memory configuration is not a differentiating factor in substitution.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.31.0001. Moisture sensitivity level is 1 (Unlimited) for all parts.
