Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PIC18LF8525-I/PT is determined by the following critical parameters:

• Core processor family (PIC)
• Core size (8-Bit)
• Operating speed (40MHz)
• Program memory capacity (48KB FLASH)
• Package type and form factor (80-TQFP 12x12)
• Voltage supply range (2V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• RoHS and environmental compliance status

The PIC18LF8527-I/PT qualifies as a direct substitute based on matching these core electrical and mechanical parameters. Variations in peripheral features, I/O count, RAM capacity, and oscillator type do not preclude substitution when the primary functional requirements align with the above criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the PIC18LF8525-I/PT and PIC18LF8527-I/PT maintain Active product status from Microchip Technology, ensuring ongoing support and availability. Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The electrical specifications, package form factor, and operating parameters are equivalent across both parts, supporting direct substitution in applications where the primary design constraints are core processor architecture, memory capacity, speed, and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can the PIC18LF8527-I/PT replace the PIC18LF8525-I/PT in existing designs?

A: Yes. Both devices share identical core processor type, operating speed (40MHz), program memory capacity (48KB FLASH), package type (80-TQFP 12x12), voltage supply range (2V ~ 5.5V), and operating temperature range (-40°C ~ 85°C). The devices are electrically and mechanically compatible for direct substitution.

Q: What are the differences between these two parts?

A: The PIC18LF8527-I/PT provides increased RAM capacity (3936 x 8 versus 3.8K x 8) and one additional I/O pin (70 versus 69). The PIC18LF8527-I/PT also features an internal oscillator option, whereas the PIC18LF8525-I/PT uses an external oscillator. Peripheral differences include HLVD support on the PIC18LF8527-I/PT versus LVD on the PIC18LF8525-I/PT.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 80-TQFP (12x12) package with identical mechanical specifications, supporting direct PCB layout compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Moisture sensitivity level (MSL 3, 168 Hours) is equivalent for both parts.

Q: What inventory considerations apply to these substitutes?

A: The PIC18LF8525-I/PT has 944 pieces in stock, while the PIC18LF8527-I/PT has 2100 pieces in stock. Availability may influence component selection based on project timeline requirements.
