Substitute Part Grouping Explanation

Substitution of the PIC16LC620T-04/SS is determined by strict equivalence across the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 896B program memory (512 x 14), 80 x 8 RAM
• Speed Rating: 4MHz operation
• I/O Count: 13 I/O pins
• Supply Voltage: 2.5V ~ 6V range
• Peripheral Set: Brown-out Detect/Reset, POR, WDT
• Package Format: 20-SSOP surface mount
• Temperature Range: 0°C ~ 70°C

The PIC16LC620-04/SS meets all substitution criteria as a direct equivalent, differing only in product status classification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC620-04/SS is the direct functional equivalent for the obsolete PIC16LC620T-04/SS. Both devices are manufactured by Microchip Technology and share identical electrical specifications, memory configuration, I/O architecture, and peripheral functionality. The substitute part maintains full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original design.

The primary distinction is product lifecycle status: the substitute part is classified as active, providing assured availability and manufacturing support. This substitution is appropriate for replacement applications, design updates, and new implementations where the PIC16LC620T-04/SS is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Are the PIC16LC620T-04/SS and PIC16LC620-04/SS pin-compatible?

A: Yes. Both devices use the 20-SSOP package with identical pinout, I/O configuration (13 pins), and electrical characteristics. Direct socket substitution is supported.

Q: What is the difference between these two part numbers?

A: The parts are functionally identical. The primary difference is product status: PIC16LC620T-04/SS is obsolete, while PIC16LC620-04/SS is active. The "T" designation in the obsolete part number does not indicate a functional variation.

Q: Can I use the PIC16LC620-04/SS in existing designs built around the PIC16LC620T-04/SS?

A: Yes. Identical memory size (896B program, 80B RAM), speed (4MHz), supply voltage range (2.5V ~ 6V), peripheral set, and package format ensure full compatibility in existing circuit designs.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (unlimited). Regulatory and environmental certifications are equivalent.

Q: What is the 20-SSOP package specification?

A: The 20-SSOP (Shrink Small Outline Package) measures 0.209 inches (5.30mm) in width and accommodates 20 pins in surface mount configuration. This package format is standard across both parts.
