Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F430CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (43 Ohms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (2512 / 6432 Metric) ensures physical fit and land pattern compatibility. Dimensions and termination count (2) must align with PCB design requirements.

Material & Environmental: Thick film composition and moisture-resistant construction maintain functional equivalence. MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions.

Compliance: ROHS3 compliance is mandatory for regulatory alignment. REACH unaffected status confirms material composition compliance.

The substitute part AC2512FK-0743RL from YAGEO meets all these criteria while adding AEC-Q200 automotive qualification, representing an upgrade path for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

RC6432F430CS (Samsung Electro-Mechanics): Select this part for standard industrial applications where ROHS3 compliance and moisture resistance are required. Active production status and 710-piece inventory support immediate procurement. Suitable for general-purpose circuit applications within the specified temperature and power parameters.

AC2512FK-0743RL (YAGEO): Select this part for automotive and mission-critical applications requiring AEC-Q200 qualification. The automotive-grade certification provides enhanced reliability assurance for demanding environments. Higher inventory availability (5732 pieces) supports volume production requirements. Dimensions remain within acceptable tolerance for 2512 package footprints.

Both parts maintain identical electrical performance, thermal characteristics, and compliance certifications. Selection between them depends on application requirements: standard industrial use favors the Samsung part, while automotive or high-reliability applications benefit from the YAGEO AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-0743RL replace RC6432F430CS in existing designs?

A: Yes. Both parts share identical resistance (43 Ohms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Dimensional variations (0.248" vs 0.250" length; 0.126" vs 0.122" width) fall within standard 2512 package tolerances and do not affect PCB land pattern compatibility.

Q: What is the significance of AEC-Q200 qualification on the YAGEO part?

A: AEC-Q200 is an automotive industry standard qualification demonstrating enhanced reliability testing, including thermal cycling, mechanical shock, and long-term stability validation. This certification is required for automotive applications but is not necessary for standard industrial use.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Compliance profiles are identical.

Q: Does packaging format affect substitution?

A: The RC6432F430CS is supplied in standard packaging, while AC2512FK-0743RL is supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical or mechanical compatibility. Tape & Reel format is standard for high-volume SMD assembly operations.

Q: What are the dimensional tolerances for the 2512 package?

A: The 2512 package specification allows length variation of approximately 0.002" and width variation of approximately 0.004". Both parts fall within these tolerances: Samsung (6.30mm x 3.20mm) and YAGEO (6.35mm x 3.10mm) are dimensionally compatible for standard PCB designs.

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

A: Yes, provided the application does not require AEC-Q200 certification. For applications requiring automotive qualification, only AC2512FK-0743RL should be used. For standard industrial applications, both parts are functionally equivalent.
