Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LC622-04E/SS is determined by strict alignment of the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating speed (4MHz)
• Program memory capacity and type (4.6KB OTP)
• RAM capacity (128 x 8)
• I/O pin count (13)
• Supply voltage range (2.5V ~ 6V)
• Package type and dimensions (20-SSOP)
• Peripheral feature set (Brown-out Detect/Reset, POR, WDT)

The PIC16LC622-04I/SS qualifies as a direct substitute based on complete alignment across all functional and electrical parameters. The primary distinction lies in product status and operating temperature range, which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LC622-04I/SS is a direct functional equivalent to the PIC16LC622-04E/SS. Both devices share identical electrical specifications, memory architecture, I/O configuration, and package geometry. The substitute part carries active product status from Microchip Technology, ensuring ongoing availability and supply chain stability compared to the obsolete main part number.

Both variants maintain ROHS3 compliance and carry identical REACH and ECCN classifications, satisfying regulatory requirements for equivalent component selection. The operating temperature range of the substitute (-40°C ~ 85°C) is narrower than the main part (-40°C ~ 125°C); applications requiring operation above 85°C must retain the original part number or evaluate alternative device families.

Frequently Asked Questions (FAQ)

Q: Can PIC16LC622-04I/SS be used as a direct replacement for PIC16LC622-04E/SS in existing designs?

A: Yes, provided the application does not require operation above 85°C. All electrical parameters, memory specifications, I/O configuration, and package dimensions are identical. Firmware and PCB layout require no modification.

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

A: The main part (PIC16LC622-04E/SS) is obsolete with an extended operating temperature range (-40°C ~ 125°C). The substitute (PIC16LC622-04I/SS) is active with a standard industrial temperature range (-40°C ~ 85°C).

Q: Are there any package or pinout differences?

A: No. Both devices use the 20-SSOP package with identical pin assignments, dimensions (0.209" × 5.30mm width), and mechanical specifications.

Q: Do compliance certifications differ between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS classifications.

Q: What should I consider when selecting between these parts?

A: Evaluate your application's maximum operating temperature requirement. If sustained operation above 85°C is necessary, the original part number must be retained. For standard industrial applications within the -40°C ~ 85°C range, the substitute offers superior availability and active product support.
