Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications):

RC0402FR-07931RL (YAGEO) functions as a direct equivalent to RC1005F9310CS. Both components share identical electrical specifications, power rating, and package dimensions. Selection between these two parts depends on packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel®) and supply chain availability.

Upgraded Alternative (Higher Power Rating):

ERJ-2RKF9310X (Panasonic Electronic Components) provides an upgraded substitute with increased power rating of 0.1W (1/10W) compared to the 0.063W (1/16W) specification of the main part. This component carries AEC-Q200 automotive qualification. The higher power rating permits operation in applications with greater thermal stress while maintaining all other electrical and mechanical parameters. This part is suitable for designs requiring automotive-grade reliability.

Automotive-Qualified Alternatives (AEC-Q200):

CRCW0402931RFKED (Vishay Dale) and RMCF0402FT931R (Stackpole Electronics Inc) both provide AEC-Q200 automotive qualification with identical power ratings and specifications to the main part. These components are appropriate for applications requiring automotive-grade component certification while maintaining the original 0.063W power specification.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature ranges. Product status is Active for all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07931RL replace RC1005F9310CS in any application?

A: RC0402FR-07931RL is a direct electrical and mechanical equivalent. Both components share identical resistance, tolerance, power rating, package dimensions, and operating specifications. Substitution is valid across all applications where RC1005F9310CS is specified, with the only difference being packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Q: What is the difference between the 0.063W and 0.1W power-rated versions?

A: Power rating indicates the maximum continuous power dissipation the component can handle. ERJ-2RKF9310X is rated at 0.1W (1/10W), while RC1005F9310CS and most other substitutes are rated at 0.063W (1/16W). The higher power rating of ERJ-2RKF9310X allows operation in circuits with greater power dissipation. In applications where actual power dissipation remains below 0.063W, both versions perform identically.

Q: Are AEC-Q200 rated parts suitable for non-automotive applications?

A: AEC-Q200 certification indicates automotive-grade reliability and qualification testing. These parts (CRCW0402931RFKED, RMCF0402FT931R, ERJ-2RKF9310X) are fully functional in non-automotive applications. The additional qualification represents enhanced reliability and does not restrict use in other industries.

Q: Does packaging format affect electrical performance?

A: Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affects handling, storage, and assembly processes but does not alter electrical performance. Selection depends on manufacturing equipment compatibility and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance certification, matching the compliance status of RC1005F9310CS. All components also maintain MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: All substitute parts share identical 0402 (1005 Metric) package dimensions and footprint specifications. They are mechanically and electrically interchangeable on PCB assemblies designed for 0402 resistors with 931 Ohms ±1% specifications.
