CPF0603F82K5C1 Equivalent & Substitute Parts

Part Overview

The CPF0603F82K5C1 is an 82.5 kOhms ±1% thin film chip resistor manufactured by TE Connectivity Passive Product in the 0603 (1608 Metric) package format. This component is rated for 0.063W (1/16W) power dissipation with a temperature coefficient of ±50ppm/°C and operates across the temperature range of -55°C to 155°C. The part is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status with 813 units in stock.

Equivalent and substitute parts are necessary when the original component becomes unavailable, when design requirements demand enhanced performance specifications such as improved tolerance or higher power ratings, or when supply chain optimization requires alternative sourcing from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the CPF0603F82K5C1 is determined by the following critical parameters: identical resistance value (82.5 kOhms), identical package format (0603/1608 Metric), thin film composition, and compatible operating temperature range (-55°C to 155°C).

Tolerance, power rating, and temperature coefficient are secondary parameters that define upgrade or downgrade relationships. Parts with equal or tighter tolerance specifications, equal or higher power ratings, and equal or lower temperature coefficients are classified as direct substitutes or upgrades. Parts with looser tolerance, lower power ratings, or higher temperature coefficients are classified as downgrades and are not suitable for substitution.

All substitute parts must maintain RoHS3 compliance and MSL 1 rating to ensure compatibility with existing manufacturing and storage protocols.

Engineering Selection Recommendations

Direct Substitutes (Equivalent Performance)

RT0603FRE0782K5L and MCT06030C8252FP500 are direct substitutes for the CPF0603F82K5C1. Both parts maintain identical tolerance (±1%) and temperature coefficient (±50ppm/°C) specifications while providing increased power rating (0.1W versus 0.063W). These parts are suitable for direct replacement in applications where the original component is unavailable. Both are RoHS3 compliant with MSL 1 rating and active production status.

Upgrade Substitutes (Enhanced Performance)

ERA-3AEB8252V, RG1608P-8252-B-T5, and RT0603BRD0782K5L offer improved tolerance specifications (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) with increased power rating (0.1W). These parts are suitable for applications requiring higher precision and stability. ERA-3AEB8252V carries automotive AEC-Q200 qualification. RG1608P-8252-B-T5 includes both anti-sulfur and automotive AEC-Q200 features. All three are RoHS3 compliant with MSL 1 rating and active production status.

Acceptable Downgrade Substitute

RT0603DRD0782K5L provides tolerance of ±0.5% with reduced temperature coefficient (±25ppm/°C) and increased power rating (0.1W). While tolerance is tighter than the original specification, it falls between the original ±1% and the ±0.1% upgrade options. This part is suitable for applications where moderate tolerance improvement is acceptable. RoHS3 compliant with MSL 1 rating and active production status.

Frequently Asked Questions (FAQ)

Q: Can RT0603FRE0782K5L be used as a direct replacement for CPF0603F82K5C1?

A: Yes. RT0603FRE0782K5L is a direct substitute. Both parts share identical resistance (82.5 kOhms), tolerance (±1%), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 155°C).
