Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F24R3CS is determined by strict equivalence across the following parameters:

Primary Matching Criteria:

• Resistance value: 24.3 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3

All identified substitute parts meet these electrical and mechanical parameters. Dimensional variations within supplier device package specifications (2512) are acceptable for PCB footprint compatibility. Product status and additional certifications (such as AEC-Q200 automotive qualification) are noted for application-specific requirements but do not disqualify substitution based on core electrical performance.

Parameter Comparison

Engineering Selection Recommendations

AC2512FK-0724R3L (YAGEO): Active product status with AEC-Q200 automotive qualification. Dimensions and electrical specifications are equivalent to the main part. Suitable for applications requiring automotive-grade components with continuous supply availability (4896 pieces in stock).

CRCW251224R3FKEG (Vishay Dale): Active product status with AEC-Q200 automotive qualification. Electrical parameters match the main part. Dimensional tolerances fall within acceptable PCB footprint ranges. Inventory availability is 2159 pieces.

ERJ-1TNF24R3U (Panasonic Electronic Components): Electrical specifications and package are equivalent to the main part. Product status is "Not For New Designs," indicating this part is in mature phase with limited future support. AEC-Q200 automotive qualification is provided. Inventory availability is 7916 pieces. Use only for legacy design maintenance or where existing supply contracts exist.

For new designs, AC2512FK-0724R3L or CRCW251224R3FKEG are preferred due to active product status. The main part RC6432F24R3CS remains the primary choice where Samsung Electro-Mechanics supply is established.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0724R3L replace RC6432F24R3CS directly on the PCB?

A: Yes. Both parts are 2512 (6432 Metric) package with equivalent electrical specifications (24.3 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C). Dimensional variations (0.250" x 0.122" vs. 0.248" x 0.126") are within standard PCB footprint tolerances for this package class.

Q: What is the difference between the substitute parts?

A: All substitute parts meet the core electrical and mechanical requirements. The primary differences are manufacturer (YAGEO, Vishay Dale, Panasonic), packaging format (Tape & Reel for substitutes vs. standard for main part), and product lifecycle status. AC2512FK-0724R3L and CRCW251224R3FKEG are active products; ERJ-1TNF24R3U is not recommended for new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC6432F24R3CS, AC2512FK-0724R3L, CRCW251224R3FKEG, and ERJ-1TNF24R3U are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does the AEC-Q200 rating on substitute parts affect compatibility?

A: No. AEC-Q200 is an additional automotive qualification that does not affect electrical or mechanical compatibility. Parts with AEC-Q200 certification can be used in non-automotive applications without restriction.

Q: Why is ERJ-1TNF24R3U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase with planned discontinuation. While electrically and mechanically equivalent, it should only be used for legacy design support or where existing supply agreements are in place.

Q: What is the height difference between the main part and substitutes?

A: RC6432F24R3CS has a maximum seated height of 0.026" (0.66mm), while AC2512FK-0724R3L is 0.026" (0.65mm), and CRCW251224R3FKEG and ERJ-1TNF24R3U are both 0.028" (0.70mm). These variations are within standard 2512 package specifications and do not affect PCB assembly compatibility.

Q: Can I mix different manufacturers in the same production run?

A: Yes. All parts meet identical electrical specifications and package standards. However, standard manufacturing practice recommends maintaining single-source components per production batch to ensure consistent performance and traceability.
