Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2152CS is determined by strict equivalence across the following critical parameters: resistance value (21.5 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are categorized as follows:

Direct Equivalents maintain all electrical and mechanical specifications identical to the main part, with variations only in packaging format (Cut Tape vs. Tape & Reel) or manufacturer series designation.

Upgrade Substitutes provide enhanced performance characteristics—specifically increased power rating (0.1W vs. 0.063W)—while maintaining all other critical parameters. These parts support applications requiring higher thermal headroom without circuit redesign.

Similar Substitutes include automotive-qualified variants (AEC-Q200 rated) that meet or exceed the base specification. These parts are suitable for applications requiring automotive-grade reliability and traceability, provided the application permits the additional qualification overhead.

All substitute parts listed maintain identical resistance, tolerance, package dimensions, temperature coefficient, and operating temperature range as the RC1005F2152CS.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (CR0402-FX-2152GLF, RC0402FR-0721K5L): These parts are suitable for direct substitution in applications where the primary requirement is electrical and mechanical compatibility. CR0402-FX-2152GLF from Bourns Inc. is available in Tape & Reel packaging, while RC0402FR-0721K5L from YAGEO offers moisture resistant construction matching the original specification. Both maintain identical power rating and thermal characteristics.

Upgrade Substitute (ERJ-2RKF2152X): The Panasonic ERJ-2RKF2152X provides increased power dissipation capability (0.1W vs. 0.063W) while maintaining all other electrical parameters. This part is suitable for applications requiring enhanced thermal margin or where circuit redesign permits utilization of the higher power rating. Automotive AEC-Q200 qualification provides additional reliability assurance for demanding environments.

Automotive-Qualified Substitutes (AC0402FR-0721K5L, CRCW040221K5FKED, RMCF0402FT21K5): These parts carry AEC-Q200 automotive qualification and are suitable for applications requiring automotive-grade component traceability, reliability documentation, and supply chain qualification. All three maintain the base electrical specification (21.5 kOhms, ±1%, 0.063W) with the addition of automotive qualification. Selection among these three should be based on packaging preference (Tape & Reel vs. Cut Tape & Digi-Reel) and supplier availability.

All listed substitutes maintain ROHS3 compliance, REACH Unaffected status, and EAR99 classification, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2152GLF be used as a direct replacement for RC1005F2152CS?

A: Yes. CR0402-FX-2152GLF is electrically and mechanically equivalent to RC1005F2152CS. Both parts specify 21.5 kOhms ±1% resistance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and manufacturer series designation. Verify packaging compatibility with assembly equipment before procurement.

Q: What is the difference between RC0402FR-0721K5L and RC1005F2152CS?

A: RC0402FR-0721K5L from YAGEO is electrically identical to RC1005F2152CS from Samsung Electro-Mechanics. Both specify 21.5 kOhms ±1%, 0.063W, 0402 package, and moisture resistant construction. RC0402FR-0721K5L is available in Cut Tape & Digi-Reel packaging options, providing procurement flexibility. No circuit modification is required for substitution.

Q: When should ERJ-2RKF2152X be selected over the base specification?

A: ERJ-2RKF2152X should be selected when the application requires higher power dissipation capability (0.1W vs. 0.063W) or when automotive AEC-Q200 qualification is mandated. The increased power rating provides thermal margin in high-current or high-ambient-temperature environments. All other electrical parameters remain identical to RC1005F2152CS.

Q: Are automotive-qualified parts (AC0402FR-0721K5L, CRCW040221K5FKED, RMCF0402FT21K5) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed commercial-grade specifications and are fully compatible with non-automotive applications. AEC-Q200 qualification indicates enhanced reliability testing and traceability. Selection should be based on application requirements, cost considerations, and supply chain preferences rather than automotive qualification alone.

Q: What packaging formats are available for 21.5 kOhms ±1% 0402 resistors?

A: Available packaging formats include Cut Tape (CT), Tape & Reel (TR), and Digi-Reel® options. CR0402-FX-2152GLF, AC0402FR-0721K5L, and RMCF0402FT21K5 are supplied in Tape & Reel format. RC1005F2152CS, RC0402FR-0721K5L, ERJ-2RKF2152X, and CRCW040221K5FKED are available in Cut Tape and/or Digi-Reel formats. Verify packaging compatibility with assembly equipment specifications.

Q: Do all substitute parts maintain moisture resistant construction?

A: RC1005F2152CS and RC0402FR-0721K5L explicitly specify moisture resistant construction. CR0402-FX-2152GLF, ERJ-2RKF2152X, CRCW040221K5FKED, and RMCF0402FT21K5 do not list moisture resistant as a feature. AC0402FR-0721K5L combines automotive AEC-Q200 qualification with moisture resistant construction. For applications requiring moisture resistance, select RC0402FR-0721K5L or AC0402FR-0721K5L.

Q: Are all listed parts ROHS3 compliant?

A: Yes. All substitute parts listed (CR0402-FX-2152GLF, RC0402FR-0721K5L, ERJ-2RKF2152X, AC0402FR-0721K5L, CRCW040221K5FKED, RMCF0402FT21K5) are ROHS3 compliant and REACH Unaffected, matching the compliance status of RC1005F2152CS.
