RC1005F2940CS Equivalent & Substitute Parts

Part Overview

The RC1005F2940CS is a 294 Ohms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This surface mount device is rated at 0.063W (1/16W) power dissipation with moisture resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when design requirements necessitate alternative sourcing options.

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2940CS is determined by strict equivalence across the following critical parameters: resistance value (294 Ohms), 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).

The identified substitute parts are grouped into three categories based on functional equivalence:

Direct Equivalents maintain identical electrical specifications and power rating (0.063W / 1/16W). These parts are pin-compatible, dimensionally identical, and suitable for one-to-one replacement without circuit redesign.

Upgrade Option provides enhanced power rating (0.1W / 1/10W) with automotive AEC-Q200 qualification, enabling use in applications requiring higher reliability or thermal margin while maintaining all other electrical parameters.

Similar Parts offer equivalent electrical performance with automotive AEC-Q200 qualification, providing alternative sourcing from different manufacturers with identical form factor and electrical characteristics.

All substitute parts share the same package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), maximum seated height (0.016" / 0.40mm), and two-terminal configuration.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-2940GLF (Bourns Inc.) and RC0402FR-07294RL (YAGEO) are functionally identical to the primary part RC1005F2940CS. Both maintain 0.063W power rating, ±1% tolerance, and 0402 package specifications. RC0402FR-07294RL includes moisture resistant construction matching the original specification. Both parts carry ROHS3 compliance and MSL 1 rating. Selection between these direct equivalents depends on inventory availability and supply chain requirements.

Upgrade Path: ERJ-2RKF2940X (Panasonic Electronic Components) provides increased power dissipation capability at 0.1W (1/10W) while maintaining all other electrical parameters. This part includes automotive AEC-Q200 qualification, suitable for applications requiring enhanced reliability or thermal performance margins. The upgrade is electrically compatible and physically interchangeable within the same package footprint.

Automotive-Qualified Alternatives: CRCW0402294RFKED (Vishay Dale) and RMCF0402FT294R (Stackpole Electronics Inc) offer equivalent electrical specifications with automotive AEC-Q200 qualification at the original 0.063W power rating. These parts are suitable for designs requiring automotive-grade component qualification while maintaining form factor and electrical performance parity with the primary part.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 classification consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2940GLF replace RC1005F2940CS in existing designs without modification?

A: Yes. CR0402-FX-2940GLF is a direct equivalent with identical resistance (294 Ohms), tolerance (±1%), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). Physical dimensions and termination configuration are identical, enabling one-to-one PCB replacement.

Q: What is the difference between the main part and ERJ-2RKF2940X?

A: ERJ-2RKF2940X provides higher power rating (0.1W versus 0.063W) and includes automotive AEC-Q200 qualification. All other electrical parameters remain identical. This part is suitable for applications requiring enhanced thermal capability or automotive-grade reliability.

Q: Are CRCW0402294RFKED and RMCF0402FT294R suitable for non-automotive applications?

A: Yes. Both parts meet all electrical and physical specifications for general industrial applications. The automotive AEC-Q200 qualification represents an additional quality assurance level and does not restrict use in non-automotive designs.

Q: Does the absence of "Moisture Resistant" designation in CR0402-FX-2940GLF affect substitution suitability?

A: Substitution suitability depends on circuit-level moisture exposure requirements. CR0402-FX-2940GLF maintains MSL 1 (Unlimited) rating identical to the primary part. If moisture resistance is a critical design requirement, RC0402FR-07294RL explicitly includes moisture resistant construction.

Q: Can these substitute parts be mixed in the same production batch?

A: All substitute parts maintain identical electrical specifications, package format, and compliance certifications. Physical interchangeability is confirmed across all identified substitutes. Production batch mixing is permissible from an electrical and mechanical standpoint; however, supply chain and traceability protocols should be followed per organizational procedures.

Q: What inventory levels are available for each substitute part?

A: Current inventory status is provided in the part specifications. CR0402-FX-2940GLF (Bourns) shows 45,583 units; RC0402FR-07294RL (YAGEO) shows 10,400 units; ERJ-2RKF2940X (Panasonic) shows 77,806 units; CRCW0402294RFKED (Vishay Dale) shows 69,384 units; RMCF0402FT294R (Stackpole) shows 39,269 units. Inventory levels are subject to change and should be confirmed with suppliers for current availability.
