Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across all critical electrical and mechanical parameters. The following criteria establish valid substitutes for RC6432F242CS:

Mandatory Matching Parameters:

• Resistance value: 2.4 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture resistance: Required
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel, Cut Tape, Digi-Reel)
• Physical dimensions within tolerance (length ±0.002", width ±0.004", height ±0.002")
• Additional certifications (AEC-Q200 automotive qualification is additive, not restrictive)

All three substitute parts meet these criteria and are classified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically equivalent to the RC6432F242CS and support direct replacement in circuit designs.

RC2512FK-072K4L (YAGEO): This direct equivalent maintains identical electrical specifications and moisture resistance. YAGEO series RC_L components are active production items with high inventory availability (8741 units). Selection is appropriate for applications requiring standard industrial-grade thick film resistors without automotive certification requirements.

CRCW25122K40FKEG (Vishay Dale): This substitute adds AEC-Q200 automotive qualification to the base specification. The CRCW2512 series is suitable for automotive and high-reliability applications where AEC-Q200 certification is mandated or preferred. Inventory level is 3607 units. Physical dimensions show minor variation within tolerance (height 0.028" vs. 0.026" maximum).

RMCF2512FT2K40 (Stackpole Electronics): This substitute also includes AEC-Q200 automotive qualification. The RMCF series is designed for automotive applications and maintains identical physical dimensions to the Samsung original (0.248" L x 0.126" W). Inventory availability is 8454 units, supporting high-volume procurement.

Selection between these three equivalents depends on application requirements (automotive vs. industrial), supply chain preferences, and inventory availability. All parts carry ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-072K4L replace RC6432F242CS in automotive applications?

A: RC2512FK-072K4L is electrically and mechanically equivalent but does not carry AEC-Q200 automotive certification. For automotive applications requiring AEC-Q200 qualification, use CRCW25122K40FKEG or RMCF2512FT2K40 instead.

Q: What is the difference between the three substitute parts?

A: All three substitutes match the RC6432F242CS in resistance (2.4 kOhms), tolerance (±1%), power rating (1W), package (2512), and operating specifications. The primary difference is AEC-Q200 automotive certification, which is present in CRCW25122K40FKEG and RMCF2512FT2K40 but not in RC2512FK-072K4L.

Q: Are there physical dimension differences between these parts?

A: Physical dimensions are within manufacturing tolerance. RC6432F242CS and RMCF2512FT2K40 share identical length and width (0.248" x 0.126"). RC2512FK-072K4L shows minor variation (0.250" L x 0.122" W) and CRCW25122K40FKEG (0.248" L x 0.124" W). All dimensions remain within the 2512 package specification and support identical PCB footprints.

Q: Do all substitutes support the same packaging formats?

A: RC6432F242CS is supplied in standard packaging. RC2512FK-072K4L is available in Tape & Reel (TR). CRCW25122K40FKEG is available in Cut Tape (CT) and Digi-Reel. RMCF2512FT2K40 is available in Tape & Reel (TR). Packaging format selection depends on assembly process requirements and volume.

Q: Are all substitutes RoHS3 compliant?

A: Yes. RC6432F242CS, RC2512FK-072K4L, CRCW25122K40FKEG, and RMCF2512FT2K40 are all ROHS3 compliant with MSL 1 (Unlimited) rating, supporting standard lead-free PCB assembly processes.

Q: Which substitute offers the best inventory availability?

A: RC2512FK-072K4L (YAGEO) offers the highest inventory with 8741 units in stock, followed by RMCF2512FT2K40 (Stackpole) with 8454 units. CRCW25122K40FKEG (Vishay Dale) has 3607 units available.
