Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F24R3CS is determined by strict equivalence across the following critical parameters: resistance value (24.3 Ohms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH Unaffected, EAR99).

Substitute parts are categorized into three groups:

Direct Equivalents maintain identical electrical specifications and power rating (0.063W / 1/16W). These parts are pin-compatible and functionally interchangeable without circuit modification.

Upgrade Substitutes provide higher power rating (0.1W / 1/10W) while maintaining all other electrical parameters. These parts offer enhanced thermal performance and are backward-compatible for applications not requiring the original 1/16W specification.

Similar Substitutes include automotive-qualified variants (AEC-Q200) with identical or equivalent electrical and mechanical specifications. These parts meet additional automotive reliability standards and are suitable for applications requiring automotive-grade components.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-24R3GLF (Bourns Inc.) and RC0402FR-0724R3L (YAGEO) are direct functional equivalents to the RC1005F24R3CS. Both maintain identical electrical specifications, package format, and power rating. RC0402FR-0724R3L includes moisture-resistant features matching the original part. Selection between these options is based on supply availability and procurement requirements.

Upgrade Selection: ERJ-2RKF24R3X (Panasonic Electronic Components) provides higher power rating (0.1W vs. 0.063W) while maintaining all other electrical parameters. This part is suitable for applications where thermal margin improvement is beneficial. The Panasonic part includes Automotive AEC-Q200 qualification, extending its applicability to automotive-grade designs.

Automotive-Grade Selection: CRCW040224R3FKED (Vishay Dale) and RMCF0402FT24R3 (Stackpole Electronics Inc) are automotive-qualified alternatives with AEC-Q200 certification. These parts maintain the original 1/16W power rating and are appropriate for designs requiring automotive reliability standards. CRCW040224R3FKED offers higher inventory availability (16,563 pcs), while RMCF0402FT24R3 provides an alternative from Stackpole Electronics.

All substitute parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes, matching the regulatory status of the original RC1005F24R3CS.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-24R3GLF replace RC1005F24R3CS in existing designs without modification?

A: Yes. CR0402-FX-24R3GLF is a direct equivalent with identical resistance (24.3 Ω), tolerance (±1%), power rating (0.063W), package format (0402), and operating temperature range (-55°C ~ 155°C). No circuit modification is required.

Q: What is the difference between the RC1005F24R3CS and ERJ-2RKF24R3X?

A: The primary difference is power rating: RC1005F24R3CS is rated at 0.063W (1/16W), while ERJ-2RKF24R3X is rated at 0.1W (1/10W). All other electrical parameters are identical. ERJ-2RKF24R3X includes Automotive AEC-Q200 qualification. The higher power rating provides additional thermal capability.

Q: Are automotive-qualified parts (CRCW040224R3FKED, RMCF0402FT24R3) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed general-purpose specifications and are fully compatible with non-automotive designs. AEC-Q200 certification indicates enhanced reliability testing and is not restrictive for general-purpose use.

Q: Does the 0402 package format remain consistent across all substitute parts?

A: Yes. All substitute parts use the 0402 (1005 Metric) package format with identical physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm). PCB footprints and assembly processes are interchangeable.

Q: What is Moisture Sensitivity Level 1 (MSL 1), and does it apply to all listed parts?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts, including the RC1005F24R3CS and all substitutes, carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, matching the regulatory compliance of the original RC1005F24R3CS. All parts are classified as EAR99 for export control purposes.
