Substitute Part Grouping Explanation

Substitution for the PIC16C622T-04E/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Program Memory: 4.6KB (2K x 14) OTP
• RAM Configuration: 128 x 8 bytes
• I/O Count: 13 pins
• Operating Voltage: 3V ~ 6V
• Clock Speed: 4MHz
• Package: 20-SSOP form factor
• Peripherals: Brown-out Detect/Reset, POR, WDT

The substitute parts identified maintain identical electrical and mechanical specifications across these parameters, ensuring functional compatibility in existing designs. Variations in product status and operating temperature ranges are noted but do not affect core substitutability.

Parameter Comparison

Engineering Selection Recommendations

PIC16C622-04E/SS is the primary substitute for the obsolete PIC16C622T-04E/SS. Both parts maintain identical electrical specifications and operating temperature range (-40°C to 125°C). The PIC16C622-04E/SS carries Active product status, ensuring continued availability and manufacturing support. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

PIC16C622-04I/SS is an alternative substitute with identical core specifications. The key distinction is the reduced operating temperature range (-40°C to 85°C), which limits its application to designs not requiring the full upper temperature capability of the main part. This part is also Active status and maintains full compliance certifications. Selection of this part requires confirmation that the application's maximum operating temperature does not exceed 85°C.

Both substitute parts are verified as programmable through DiGi-Electronics and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating robust handling characteristics suitable for standard manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can PIC16C622-04I/SS replace PIC16C622T-04E/SS in all applications?

A: PIC16C622-04I/SS is functionally equivalent for applications operating within -40°C to 85°C. Applications requiring operation above 85°C must use PIC16C622-04E/SS or the original part to maintain the full -40°C to 125°C temperature specification.

Q: Are there any package differences between these parts?

A: All three parts use identical 20-SSOP packaging (0.209", 5.30mm width). No PCB layout modifications are required for substitution.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute parts (PIC16C622-04E/SS and PIC16C622-04I/SS) are in Active production status, ensuring long-term availability, manufacturing support, and consistent supply chain access compared to the obsolete main part.

Q: Are compliance certifications maintained across all three parts?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.31.0001) classifications.

Q: What memory specifications must match for substitution?

A: Program memory (4.6KB OTP), RAM (128 x 8), and I/O count (13 pins) must remain constant. All substitute parts maintain these specifications identically.
