Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F302CS are classified into three categories based on electrical and mechanical parameter alignment:

Direct Equivalents maintain identical specifications across all critical parameters: 3 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and MSL 1 rating. These parts are pin-compatible and functionally interchangeable without circuit modification.

Upgrade Parts provide enhanced specifications while maintaining core electrical parameters. The ERJ-2RKF3001X increases power rating to 0.1W (1/10W) and includes Automotive AEC-Q200 qualification, suitable for applications requiring higher power dissipation or automotive-grade reliability.

Similar Parts match all electrical and mechanical specifications but include additional certifications such as Automotive AEC-Q200 qualification or alternative packaging formats. These parts are functionally equivalent with enhanced environmental or application-specific ratings.

Substitution eligibility is determined by matching: resistance value (3 kOhms), tolerance (±1%), package format (0402), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and MSL rating (1).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (No Circuit Modification Required):

CR0402-FX-3001GLF (Bourns Inc.), CRG0402F3K0 (TE Connectivity), RC0402FR-073KL (YAGEO), AC0402FR-073KL (YAGEO), CRCW04023K00FKED (Vishay Dale), and RMCF0402FT3K00 (Stackpole Electronics) are functionally equivalent to RC1005F302CS. All parts maintain identical electrical specifications, package dimensions, and RoHS3 compliance. Selection among these direct equivalents is based on availability, supply chain preference, and packaging format requirements (Tape & Reel versus Cut Tape & Digi-Reel).

Upgrade Substitution (Enhanced Specifications):

ERJ-2RKF3001X (Panasonic Electronic Components) provides increased power rating of 0.1W (1/10W) compared to the 0.063W rating of RC1005F302CS, with Automotive AEC-Q200 qualification. This part is suitable for applications requiring higher power dissipation capability or automotive-grade reliability certification while maintaining all other electrical parameters.

Compliance Considerations:

All substitute parts listed are RoHS3 compliant and MSL 1 rated, ensuring compatibility with standard PCB assembly processes and environmental regulations. Parts with Automotive AEC-Q200 ratings (ERJ-2RKF3001X, AC0402FR-073KL, CRCW04023K00FKED, RMCF0402FT3K00) are qualified for automotive applications and provide enhanced reliability documentation.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-3001GLF replace RC1005F302CS without any circuit changes?

A: Yes. CR0402-FX-3001GLF is a direct equivalent with identical resistance (3 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No circuit modification is required.

Q: What is the difference between RC0402FR-073KL and AC0402FR-073KL?

A: Both are YAGEO 3 kOhms ±1% 0402 resistors with identical electrical specifications. AC0402FR-073KL includes Automotive AEC-Q200 qualification and is rated for automotive applications, while RC0402FR-073KL is the standard industrial version. The AC variant has a maximum seated height of 0.015" (0.37mm) compared to 0.016" (0.40mm) for RC0402FR-073KL.

Q: Is ERJ-2RKF3001X a direct substitute for RC1005F302CS?

A: ERJ-2RKF3001X is functionally compatible but not a direct equivalent. It provides an upgraded power rating of 0.1W (1/10W) versus 0.063W and includes Automotive AEC-Q200 certification. All other electrical parameters match. Use this part when higher power dissipation or automotive qualification is required.

Q: What packaging formats are available for these substitute parts?

A: Substitute parts are available in two packaging formats: Tape & Reel (TR) for automated assembly and Cut Tape & Digi-Reel for manual or mixed-mode assembly. CR0402-FX-3001GLF, CRG0402F3K0, ERJ-2RKF3001X, AC0402FR-073KL, and RMCF0402FT3K00 are supplied in Tape & Reel format. RC0402FR-073KL and CRCW04023K00FKED are supplied in Cut Tape & Digi-Reel format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and MSL 1 rated, meeting standard environmental and regulatory requirements for PCB assembly.

Q: Which substitute part has the highest inventory availability?

A: RC0402FR-073KL (YAGEO) has the highest inventory with 500,100 pieces in stock, followed by ERJ-2RKF3001X (Panasonic) with 289,325 pieces.
