Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (2.26 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), termination count (2), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are categorized as follows:

Direct Equivalents: Parts matching all electrical and mechanical specifications of the main part, including identical power rating (0.063W / 1/16W) and moisture-resistant features where applicable.

Upgrade Substitute: Parts with enhanced power rating (0.1W / 1/10W) that maintain all other specifications and add automotive AEC-Q200 qualification, suitable for applications requiring higher thermal margin or automotive-grade reliability.

Similar Substitutes: Parts meeting all core electrical and mechanical parameters with automotive AEC-Q200 qualification added, providing enhanced reliability for automotive and industrial applications while maintaining identical power and package specifications.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2261GLF replace RC1005F2261CS in any application?

A: CR0402-FX-2261GLF is a direct electrical and mechanical equivalent with identical resistance, tolerance, power rating, package, and temperature specifications. It is suitable for direct replacement in non-automotive applications where moisture-resistant construction is not specified as a requirement.

Q: What is the difference between RC0402FR-072K26L and RC1005F2261CS?

A: RC0402FR-072K26L (YAGEO) matches all electrical parameters and includes moisture-resistant construction identical to RC1005F2261CS. Both are rated 0.063W, ±1% tolerance, 0402 package, and ROHS3 compliant. The primary difference is manufacturer.

Q: When should ERJ-2RKF2261X be selected instead of the main part?

A: ERJ-2RKF2261X is selected when applications require automotive AEC-Q200 qualification or when higher power dissipation margin (0.1W vs. 0.063W) is beneficial for thermal performance. All other electrical and mechanical specifications remain equivalent.

Q: Are AC0402FR-072K26L and RMCF0402FT2K26 interchangeable with RC1005F2261CS?

A: Both parts are electrically and mechanically equivalent to RC1005F2261CS with identical 2.26 kOhms resistance, ±1% tolerance, 0.063W power rating, and 0402 package. Both include AEC-Q200 automotive qualification as an additional feature. AC0402FR-072K26L includes moisture-resistant construction.

Q: Does the 0402 package dimension remain consistent across all substitute parts?

A: All substitute parts maintain 0402 (1005 Metric) package format with dimensions 0.039" L x 0.020" W (1.00mm x 0.50mm). Height-seated maximum specifications are 0.016" (0.40mm) for most parts, with AC0402FR-072K26L at 0.015" (0.37mm), representing negligible variation within standard PCB assembly tolerances.
