Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (61.9 Ohms), 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 electrical and mechanical specifications including power rating (0.063W / 1/16W), moisture resistance, and packaging format (Tape & Reel or Cut Tape).

Upgrade Substitute provides enhanced power rating (0.1W / 1/10W) while maintaining all other core parameters, suitable for applications requiring higher thermal margin.

Similar Substitutes include automotive AEC-Q200 qualification in addition to base electrical specifications, applicable to automotive and high-reliability applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (CR0402-FX-61R9GLF, RC0402FR-0761R9L): These parts provide full electrical and mechanical compatibility with the RC1005F61R9CS. Selection between these options is based on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and supplier availability. Both maintain ROHS3 compliance and MSL 1 rating.

Upgrade Substitute (ERJ-2RKF61R9X): This Panasonic component offers increased power dissipation capability (0.1W versus 0.063W) while maintaining identical resistance, tolerance, and package specifications. The automotive AEC-Q200 qualification provides additional reliability assurance. This option is suitable for applications where thermal margin enhancement is beneficial without circuit redesign.

Similar Substitutes with Automotive Qualification (CRCW040261R9FKED, RMCF0402FT61R9): These parts are specified for automotive and high-reliability applications with AEC-Q200 certification. They maintain the original 0.063W power rating and all core electrical parameters. Selection is appropriate when automotive-grade components are required by specification or application environment.

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

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-61R9GLF be used as a direct replacement for RC1005F61R9CS?

A: Yes. Both parts share identical resistance (61.9 Ohms), tolerance (±1%), power rating (0.063W), package (0402), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is packaging format: CR0402-FX-61R9GLF is supplied in Tape & Reel format.

Q: What is the advantage of using ERJ-2RKF61R9X over the original RC1005F61R9CS?

A: The ERJ-2RKF61R9X provides higher power dissipation (0.1W versus 0.063W) while maintaining all other electrical specifications. This increased power rating offers thermal margin for applications operating near maximum power limits. Additionally, this part carries automotive AEC-Q200 qualification for enhanced reliability documentation.

Q: Are the automotive-qualified parts (CRCW040261R9FKED, RMCF0402FT61R9) interchangeable with the standard RC1005F61R9CS?

A: Yes, from an electrical and mechanical standpoint. Both automotive-qualified parts maintain identical resistance, tolerance, power rating, package, and temperature specifications. The AEC-Q200 qualification represents additional manufacturing and testing rigor. Use these parts when automotive-grade components are specified or when operating environment demands higher reliability assurance.

Q: Does moisture resistance differ between substitute parts?

A: The RC1005F61R9CS and RC0402FR-0761R9L are explicitly specified as moisture resistant. The CR0402-FX-61R9GLF does not list moisture resistance as a feature. All parts maintain MSL 1 (Unlimited) rating. For applications requiring moisture-resistant construction, RC0402FR-0761R9L is the preferred equivalent.

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

A: All listed parts are ROHS3 compliant, REACH Unaffected, and carry identical EAR99 classification. From a regulatory standpoint, substitution is permissible. However, manufacturing and procurement practices should follow established component qualification procedures for your specific application.

Q: What packaging formats are available among the substitute parts?

A: RC1005F61R9CS, CR0402-FX-61R9GLF, ERJ-2RKF61R9X, CRCW040261R9FKED, and RMCF0402FT61R9 are supplied in Tape & Reel (TR) format. RC0402FR-0761R9L is available in Cut Tape (CT) & Digi-Reel format. Select based on your assembly equipment and procurement requirements.
