Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6043CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 604 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed 0.063W (1/16W)
• Features: Substitute parts may include additional certifications (AEC-Q200) beyond moisture resistance

All identified substitute parts meet or exceed the mandatory parameters. The RC0402FR-07604KL (YAGEO) provides direct equivalence. The ERJ-2RKF6043X (Panasonic) offers upgraded power rating (0.1W) with AEC-Q200 automotive qualification. The AC0402FR-07604KL (YAGEO), CRCW0402604KFKED (Vishay Dale), and RMCF0402FT604K (Stackpole Electronics) provide equivalent specifications with AEC-Q200 automotive certification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: RC0402FR-07604KL (YAGEO) provides identical electrical and mechanical specifications to the RC1005F6043CS. Both parts deliver 604 kOhms ±1% at 0.063W with moisture-resistant thick film construction. Selection of this substitute requires no circuit redesign or thermal analysis modifications.

Upgraded Specification: ERJ-2RKF6043X (Panasonic Electronic Components) offers increased power rating of 0.1W (1/10W) while maintaining all other critical parameters. This part includes AEC-Q200 automotive qualification. The higher power rating provides additional thermal margin in applications where the original 0.063W specification is marginal. Physical dimensions remain identical to the main part.

Automotive-Qualified Alternatives: AC0402FR-07604KL (YAGEO), CRCW0402604KFKED (Vishay Dale), and RMCF0402FT604K (Stackpole Electronics) all provide 604 kOhms ±1% at 0.063W with AEC-Q200 automotive certification. These parts are suitable for applications requiring automotive-grade component qualification while maintaining electrical equivalence to the RC1005F6043CS. AC0402FR-07604KL additionally includes moisture-resistant features matching the original part.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and Active product status. Selection among these alternatives depends on procurement availability, supply chain requirements, and application-specific automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07604KL replace RC1005F6043CS in all applications? A: Yes. RC0402FR-07604KL matches all critical electrical and mechanical parameters of RC1005F6043CS. Both parts deliver 604 kOhms ±1% at 0.063W in 0402 package with identical temperature coefficient and operating range. No circuit modifications are required.

Q: What is the difference between the main part and ERJ-2RKF6043X? A: ERJ-2RKF6043X provides higher power rating (0.1W versus 0.063W) and includes AEC-Q200 automotive certification. All other parameters including resistance, tolerance, package, and temperature range remain identical. The increased power rating provides additional thermal capability.

Q: Are the automotive-qualified substitutes (AC0402FR-07604KL, CRCW0402604KFKED, RMCF0402FT604K) suitable for non-automotive applications? A: Yes. Automotive-qualified parts exceed standard industrial specifications and function in non-automotive circuits. AEC-Q200 certification indicates enhanced reliability and stricter manufacturing controls. These parts are fully compatible with applications using the RC1005F6043CS.

Q: Do all substitute parts have the same physical dimensions? A: All substitute parts use 0402 (1005 Metric) package format with 0.039" L x 0.020" W dimensions. Height-seated maximum values are 0.016" (0.40mm) for most parts, with AC0402FR-07604KL at 0.015" (0.37mm). These minor height variations do not affect PCB assembly compatibility.

Q: What is MSL 1 rating and why does it matter? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake requirements. All listed parts carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Can these parts be used interchangeably in existing designs? A: Yes. All substitute parts maintain identical resistance value (604 kOhms), tolerance (±1%), package (0402), and temperature specifications. Direct substitution requires no design changes, PCB layout modifications, or thermal recalculation.

Q: Which substitute offers the best value for cost-sensitive applications? A: RC0402FR-07604KL (YAGEO) provides direct equivalence at standard industrial specifications. For applications requiring automotive qualification without cost premium, RMCF0402FT604K (Stackpole Electronics) offers AEC-Q200 certification with equivalent electrical performance.
