Manufacturer: Different manufacturers with equivalent specifications
Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
Features: Moisture Resistant and/or Automotive AEC-Q200 qualification (additional features do not disqualify substitution)

Substitute parts are categorized as follows:

Direct Substitutes: Parts with identical electrical specifications (27 kOhms ±5%, 0.063W, 1/16W) from alternative manufacturers.

Upgrade Substitutes: Parts with improved tolerance (±1% instead of ±5%) or higher power rating (0.1W instead of 0.063W), maintaining all other critical parameters. These parts provide enhanced performance characteristics while maintaining full compatibility.

Similar Substitutes: Parts with identical electrical specifications but additional automotive qualification (AEC-Q200) or alternative packaging, suitable for applications requiring automotive-grade components.

Engineering Selection Recommendations

Direct Substitution (RC0402JR-0727KL): The YAGEO RC0402JR-0727KL provides direct electrical and mechanical equivalence to the RC1005J273CS. Both components share identical resistance (27 kOhms), tolerance (±5%), power rating (0.063W), package format (0402), and temperature characteristics. This part is suitable for direct replacement in applications where the original Samsung component is unavailable. The YAGEO part is in active production status with 7529 units in stock.

Upgrade Substitution (RC0402FR-0727KL, CRG0402F27K, RMCF0402FT27K0): These parts offer improved tolerance specification (±1% versus ±5%) while maintaining all other critical parameters. The RC0402FR-0727KL from YAGEO and RMCF0402FT27K0 from Stackpole Electronics maintain the 0.063W power rating, while the CRG0402F27K from TE Connectivity provides equivalent performance. These upgrades are applicable in designs where tighter tolerance requirements are specified or where design margins benefit from improved accuracy. All three parts are ROHS3 compliant and maintain the -55°C to 155°C operating range.

Automotive-Grade Substitution (ERJ-2RKF2702X, RMCF0402FT27K0, AC0402JR-0727KL, RMCF0402JT27K0): Parts with AEC-Q200 automotive qualification are available as substitutes.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-0727KL be used as a direct replacement for RC1005J273CS?

A: Yes. The RC0402JR-0727KL from YAGEO is a direct substitute. Both parts have identical electrical specifications (27 kOhms ±5%, 0.063W), the same 0402 package format, identical temperature coefficient (±100ppm/°C), and matching operating temperature range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the main part and the upgrade substitutes?

A: Upgrade substitutes such as RC0402FR-0727KL, CRG0402F27K, and RMCF0402FT27K0 provide tighter tolerance (±1% instead of ±5%). Some upgrade options, such as ERJ-2RKF2702X, also offer higher power rating (0.1W instead of 0.063W). These upgrades maintain all other critical parameters and are fully compatible with designs specified for the original ±5% tolerance part.

Q: Are automotive-grade parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. Automotive-grade parts such as ERJ-2RKF2702X, RMCF0402FT27K0, AC0402JR-0727KL, and RMCF0402JT27K0 meet all requirements of the original RC1005J273CS and exceed the qualification standards. These parts are suitable for any application where the original part is specified, including non-automotive designs.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format differences (Tape & Reel or Cut Tape & Digi-Reel®) do not affect electrical performance or component specifications. Selection between packaging formats is determined by assembly process requirements and inventory management practices.

Q: Can parts with different power ratings be substituted?

A: Parts with equal or higher power ratings are suitable substitutes. For example, ERJ-2RKF2702X with 0.1W rating can replace the 0.063W RC1005J273CS. The higher power rating provides additional thermal margin and does not compromise circuit performance. Parts with lower power ratings are not suitable substitutes.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture bake requirements. Components with this rating do not require special storage conditions or pre-reflow baking procedures, simplifying inventory management and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original RC1005J273CS. This ensures compatibility with environmental regulations and customer requirements for restricted substance compliance.
