Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PIC16F54-I/SO are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key criteria:

• Core Architecture: Identical PIC 8-bit processor core
• Memory Configuration: Matching 768B FLASH program memory and 25 x 8 RAM
• Performance: Identical 20MHz operating speed
• I/O Count: 12 I/O pins maintained
• Voltage Range: 2V to 5.5V supply compatibility
• Package: 18-SOIC surface mount form factor
• Thermal Range: -40°C to 85°C operating temperature
• Compliance: ROHS3 and REACH compliance maintained

Parts meeting all these parameters are classified as direct substitutes and can be used interchangeably in circuit designs without modification.

Parameter Comparison

Engineering Selection Recommendations

The PIC16F54T-I/SO is a direct functional equivalent to the PIC16F54-I/SO. Both parts are manufactured by Microchip Technology and maintain identical electrical specifications, memory architecture, and thermal operating ranges. The primary distinction lies in packaging format: the PIC16F54-I/SO is supplied in Tube packaging, while the PIC16F54T-I/SO is available in Cut Tape (CT) and Digi-Reel® formats.

Both parts carry Active product status and maintain full ROHS3 and REACH compliance, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on procurement requirements and supply chain logistics rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can PIC16F54T-I/SO replace PIC16F54-I/SO in existing designs?

A: Yes. The PIC16F54T-I/SO is electrically and functionally identical to the PIC16F54-I/SO. Both parts share the same core processor, memory configuration, I/O count, voltage range, and thermal specifications. No circuit modifications are required.

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

A: The difference is packaging format only. PIC16F54-I/SO is supplied in Tube packaging, while PIC16F54T-I/SO is supplied in Cut Tape (CT) and Digi-Reel® formats. The "T" designation in PIC16F54T-I/SO indicates tape and reel packaging.

Q: Are both parts ROHS3 compliant?

A: Yes. Both PIC16F54-I/SO and PIC16F54T-I/SO are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used interchangeably in production?

A: Yes, provided your assembly process accommodates the packaging format. If your production line uses automated pick-and-place equipment, the tape and reel format (PIC16F54T-I/SO) may be more suitable. For manual assembly or lower-volume production, the tube format (PIC16F54-I/SO) may be preferred.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices are sufficient.
