Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C54-RCE/SS is determined by strict equivalence across the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Program memory capacity and type (768B OTP)
• RAM configuration (25 x 8)
• I/O pin count (12)
• Operating frequency (4MHz)
• Package form factor (20-SSOP)
• Peripheral set (POR, WDT)
• Supply voltage range compatibility
• Mounting technology (Surface Mount)

The PIC16C54-RCI/SS qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Differences in product status, operating temperature range, and packaging format do not affect functional interchangeability in applications where the substitute's specifications meet or exceed the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C54-RCI/SS is a qualified substitute for the PIC16C54-RCE/SS based on functional and electrical equivalence. Both devices maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.

The substitute part carries Active product status, providing assured long-term availability compared to the obsolete main part. The PIC16C54-RCI/SS supply voltage range (3V ~ 6.25V) encompasses the original specification (3.25V ~ 6V), ensuring compatibility with existing power supply designs.

The operating temperature range of the substitute (-40°C ~ 85°C) is narrower than the main part (-40°C ~ 125°C). Selection of the substitute requires confirmation that the application's maximum operating temperature does not exceed 85°C. For applications requiring operation above 85°C, the original part specification must be maintained or alternative solutions evaluated.

Frequently Asked Questions (FAQ)

Q: Can PIC16C54-RCI/SS replace PIC16C54-RCE/SS in all applications?

A: The PIC16C54-RCI/SS is functionally equivalent for applications operating within -40°C to 85°C. Applications requiring operation above 85°C require the original part or alternative evaluation.

Q: Are there differences in pin configuration between these parts?

A: No. Both parts use identical 20-SSOP packaging with 12 I/O pins in the same physical and electrical configuration.

Q: What is the significance of the product status difference?

A: The main part (PIC16C54-RCE/SS) is classified as obsolete, indicating discontinued manufacturing. The substitute (PIC16C54-RCI/SS) maintains Active status, ensuring ongoing availability and supply chain reliability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with identical MSL ratings of 1 (Unlimited), meeting equivalent environmental and regulatory requirements.

Q: What is the difference between the packaging designations (RCE vs. RCI)?

A: The suffix designates internal Microchip product line classifications. Both parts are supplied in 20-SSOP surface mount packages with identical mechanical specifications.

Q: Are the supply voltage ranges compatible?

A: The substitute voltage range (3V ~ 6.25V) fully encompasses the original specification (3.25V ~ 6V). Existing power supply designs require no modification.
