Key Parameters

Substitute Part Grouping Explanation

Substitution for the PIC16LC622AT-04E/SS is determined by strict equivalence across the following parameters:

• Core processor architecture (PIC 8-bit)
• Program memory capacity (4.6KB OTP)
• RAM capacity (128 x 8)
• I/O pin count (13)
• Supply voltage range (2.5V ~ 5.5V)
• Package type and dimensions (20-SSOP)
• RoHS and compliance certifications

The substitute parts identified maintain 100% compatibility across these electrical and mechanical specifications. Differences in product status (obsolete vs. active) and operating temperature ranges are noted but do not affect functional substitution within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both PIC16LC622A-04E/SS and PIC16LC622A-04I/SS are direct functional equivalents to the PIC16LC622AT-04E/SS. Selection between these substitutes is based on the following criteria:

PIC16LC622A-04E/SS is recommended for applications requiring the full operating temperature range of -40°C to 125°C. This part maintains active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

PIC16LC622A-04I/SS is suitable for applications with operating temperature requirements limited to -40°C to 85°C. This part is supplied in tube packaging and maintains active product status with identical electrical specifications and compliance certifications.

Both substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can PIC16LC622A-04E/SS and PIC16LC622A-04I/SS be used interchangeably with PIC16LC622AT-04E/SS?

A: Yes, both parts are functionally equivalent across all electrical and mechanical parameters specified for this product category. The primary differences are product status (active vs. obsolete) and operating temperature range for the -04I variant.

Q: What is the significance of the operating temperature difference between PIC16LC622A-04E/SS and PIC16LC622A-04I/SS?

A: The PIC16LC622A-04E/SS operates from -40°C to 125°C, while the PIC16LC622A-04I/SS operates from -40°C to 85°C. Selection depends on your application's thermal requirements. If your design operates above 85°C, use the -04E variant.

Q: Are there packaging differences between the substitute parts?

A: PIC16LC622A-04I/SS is supplied in tube packaging, while PIC16LC622A-04E/SS packaging is not specified in the provided data. Both use identical 20-SSOP package dimensions (0.209", 5.30mm Width).

Q: Do the substitute parts maintain the same pin configuration and I/O count?

A: Yes. Both substitute parts maintain 13 I/O pins in the same 20-SSOP package configuration as the original PIC16LC622AT-04E/SS.

Q: Are compliance certifications identical across all three parts?

A: Yes. All three parts are ROHS3 compliant with MSL rating of 1 (Unlimited), REACH unaffected status, and identical ECCN and HTSUS classifications.
