Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC16C54T-10E/SS is determined by strict alignment of the following critical parameters:

• Core processor architecture (PIC)
• Core size (8-Bit)
• Operating speed (10MHz)
• Program memory capacity and type (768B OTP)
• RAM configuration (25 x 8)
• I/O pin count (12)
• Supply voltage range (4.5V ~ 5.5V)
• Package type and physical dimensions (20-SSOP)
• Mounting configuration (Surface Mount)

The substitute part PIC16C54-10I/SS meets all electrical and mechanical compatibility criteria. The primary distinction lies in product status classification and operating temperature range specification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16C54-10I/SS is a direct functional equivalent to the PIC16C54T-10E/SS for applications operating within the -40°C to 85°C temperature range. The substitute part maintains identical electrical specifications, memory architecture, I/O configuration, and package form factor. The primary advantage of the PIC16C54-10I/SS is its active product status with verified programmability support, ensuring continued availability and manufacturing support from Microchip Technology.

For applications requiring operation above 85°C, the temperature range differential must be evaluated against specific system thermal requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, supporting equivalent regulatory and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can PIC16C54-10I/SS replace PIC16C54T-10E/SS in all applications?

A: The PIC16C54-10I/SS is electrically and mechanically compatible with the PIC16C54T-10E/SS for applications operating within -40°C to 85°C. Applications requiring operation above 85°C must evaluate the temperature range limitation.

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

A: The PIC16C54T-10E/SS is classified as obsolete, indicating discontinued manufacturing and limited availability. The PIC16C54-10I/SS maintains active status with ongoing production and support from Microchip Technology.

Q: Are the package dimensions identical?

A: Both parts use the 20-SSOP package with identical physical dimensions of 0.209" width and 5.30mm width specification, ensuring direct PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification, supporting equivalent regulatory requirements.

Q: What is the difference between the part number suffixes?

A: The suffix variation (T-10E versus -10I) reflects different temperature grade classifications and product status designations within Microchip's naming convention. The electrical and functional specifications remain identical.
