Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F274CS is determined by strict equivalence across the following critical parameters: resistance value (270 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99).

Direct Equivalents maintain identical specifications across all parameters including power rating (0.063W / 1/16W) and moisture resistance features. These parts are interchangeable without design modification.

Upgrade Substitutes exceed the original power rating specification (0.1W / 1/10W instead of 0.063W / 1/16W) while maintaining all other electrical and mechanical parameters. These parts provide enhanced thermal performance and are suitable for applications where increased power dissipation capability is beneficial.

Similar Substitutes include automotive-grade AEC-Q200 qualified alternatives that maintain core electrical specifications but add automotive qualification features. These parts are suitable for applications requiring automotive-grade reliability or when sourced from automotive-qualified suppliers.

All substitute parts share identical package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), height specifications, and termination count, ensuring mechanical compatibility in PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-2703GLF (Bourns Inc.) and RC0402FR-07270KL (YAGEO) are direct functional equivalents to the RC1005F274CS. Both maintain identical electrical specifications, package format, and power rating. Selection between these options is based on supplier availability and inventory levels. RC0402FR-07270KL offers the advantage of moisture resistant construction matching the original part specification.

Upgrade Substitute Selection: ERJ-2RKF2703X (Panasonic Electronic Components) provides enhanced power rating at 0.1W (1/10W) compared to the original 0.063W specification. This upgrade is suitable for applications where thermal margin improvement is desired. The part maintains all other electrical parameters and includes automotive AEC-Q200 qualification, supporting applications requiring automotive-grade reliability.

Automotive-Grade Alternatives: AC0402FR-07270KL (YAGEO), CRCW0402270KFKED (Vishay Dale), and RMCF0402FT270K (Stackpole Electronics Inc) are automotive-qualified alternatives with AEC-Q200 certification. These parts are appropriate for automotive applications or when procurement from automotive-qualified suppliers is required. AC0402FR-07270KL additionally includes moisture resistant construction.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2703GLF replace RC1005F274CS in existing designs without modification?

A: Yes. CR0402-FX-2703GLF is a direct equivalent with identical resistance (270 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), and operating temperature range (-55°C to 155°C). No design changes are required.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents maintain identical power ratings (0.063W). Upgrade substitutes such as ERJ-2RKF2703X provide higher power rating (0.1W) while maintaining all other electrical specifications. Upgrade substitutes are suitable when increased thermal performance is beneficial but are not required for direct replacement.

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

A: Yes. Automotive-qualified parts meet or exceed commercial-grade specifications and are suitable for any application. AEC-Q200 qualification indicates enhanced reliability testing and quality assurance. These parts may be selected for non-automotive applications when sourced from automotive-qualified suppliers or when enhanced reliability is desired.

Q: Does moisture resistant construction affect substitution compatibility?

A: Moisture resistant construction is a feature that does not impact electrical substitution compatibility. Parts with moisture resistant construction (RC1005F274CS, RC0402FR-07270KL, AC0402FR-07270KL) are functionally equivalent to parts without this feature. Selection based on moisture resistance depends on application environment requirements.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in 0402 (1005 Metric) package format with identical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and height specifications. Packaging compatibility is confirmed across all alternatives. Tape & Reel (TR) and Cut Tape (CT) packaging options are available depending on supplier and order quantity.

Q: What is the significance of ±100ppm/°C temperature coefficient across all parts?

A: Temperature coefficient of ±100ppm/°C is maintained uniformly across all substitute parts and the original specification. This parameter defines resistance value drift over temperature and is critical for circuit performance in temperature-sensitive applications. Uniform temperature coefficient ensures equivalent circuit behavior across the operating temperature range of -55°C to 155°C.

Q: Can I use ERJ-2RKF2703X as a direct replacement if my application only requires 0.063W power dissipation?

A: Yes. ERJ-2RKF2703X with 0.1W power rating is suitable for applications requiring 0.063W or less. The higher power rating provides additional thermal margin and does not negatively impact circuit performance. This upgrade substitute is appropriate for any application using the original 0.063W specification.
