Substitute Part Grouping Explanation

Substitution eligibility for the PIC16LCE623-04E/SS is determined by strict alignment of the following critical parameters:

• Core Architecture: PIC 8-bit processor
• Memory Configuration: 896B OTP program memory, 128 x 8 EEPROM, 96 x 8 RAM
• Operating Frequency: 4MHz
• I/O Pin Count: 13 pins
• Supply Voltage Range: 2.5V ~ 5.5V
• Package Type: 20-SSOP form factor
• Peripheral Set: Brown-out Detect/Reset, POR, WDT

The substitute part PIC16LCE623-04I/SS meets all core functional and electrical parameters. Differences exist only in product status, operating temperature range, and packaging format, which do not affect electrical compatibility in applications designed for the original specification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16LCE623-04I/SS is a direct functional substitute for the PIC16LCE623-04E/SS. Both devices share identical core specifications, memory architecture, I/O configuration, and peripheral functionality. The substitute part carries Active product status from Microchip Technology, ensuring continued availability and manufacturing support.

Key considerations for selection:

• Product Lifecycle: The substitute part is actively manufactured, providing supply chain continuity for applications currently using the obsolete variant.
• Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements.
• Operating Temperature: Applications operating within the -40°C to 85°C range are fully compatible with the substitute. Applications requiring operation above 85°C must retain the original part specification.
• Packaging: The substitute is supplied in tube packaging, which may differ from original procurement formats but does not affect electrical performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can PIC16LCE623-04I/SS replace PIC16LCE623-04E/SS in existing designs?

A: Yes, for applications operating within -40°C to 85°C. The devices are electrically and functionally identical across all core parameters including memory, I/O, voltage supply, and peripheral configuration. The substitute part is pin-compatible and requires no circuit modifications.

Q: What is the difference between the -04E and -04I suffixes?

A: The suffix designates the operating temperature range and product status. The -04E variant (obsolete) supports -40°C to 125°C operation. The -04I variant (active) supports -40°C to 85°C operation. Both use identical core silicon and instruction sets.

Q: Are there any package compatibility issues?

A: No. Both parts use the 20-SSOP package with identical pinout and mechanical dimensions (0.209", 5.30mm width). The substitute is supplied in tube packaging rather than standard format, but this affects only handling and storage, not PCB assembly or electrical function.

Q: Is the substitute part RoHS compliant?

A: Yes. The PIC16LCE623-04I/SS maintains ROHS3 compliance and REACH unaffected status, matching the environmental certifications of the original part.

Q: What should I do if my application requires operation above 85°C?

A: Applications requiring sustained operation above 85°C must use the original PIC16LCE623-04E/SS specification or identify alternative microcontroller solutions rated for extended temperature ranges. The substitute part is not suitable for such applications.
