Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F2154CS are identified based on strict alignment of the following critical parameters:

Electrical Equivalence: Resistance value of 2.15 MOhms, tolerance of ±1%, and power rating of 1W must be identical.

Package Compatibility: The 2512 (6432 Metric) package format is mandatory for mechanical and thermal compatibility in PCB layouts.

Composition: Thick film construction ensures consistent performance characteristics across the operating temperature range.

Temperature Performance: Operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C must be maintained.

Compliance Requirements: ROHS3 compliance and MSL 1 rating are required for regulatory and environmental compatibility.

Dimensional Tolerance: Physical dimensions (0.248" L x 0.126" W / 6.30mm x 3.20mm) and maximum seated height must accommodate existing PCB footprints.

Engineering Selection Recommendations

RC6432F2154CS (Samsung Electro-Mechanics): Select this part when the original design specification explicitly requires Samsung sourcing or when moisture-resistant thick film composition is the primary feature requirement. Product status is active with 955 units in stock. ROHS3 compliance and MSL 1 rating are confirmed.

RMCF2512FT2M15 (Stackpole Electronics Inc): This substitute part meets all electrical and mechanical equivalence criteria. The component carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Product status is active with 7647 units in inventory. ROHS3 compliance and MSL 1 rating are confirmed. The maximum seated height of 0.028" (0.70mm) is 0.002" higher than the original part but remains within standard PCB assembly tolerances. Packaging is supplied in Tape & Reel format.

Both parts are functionally interchangeable based on electrical specifications, package format, temperature performance, and regulatory compliance. Selection between them depends on sourcing availability, inventory levels, packaging requirements, and whether automotive qualification is a design requirement.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT2M15 be used as a direct replacement for RC6432F2154CS?

A: Yes. Both parts share identical resistance value (2.15 MOhms), tolerance (±1%), power rating (1W), package format (2512/6432 Metric), temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). The 0.002" difference in maximum seated height is within standard PCB assembly tolerances and does not affect mechanical compatibility.

Q: What is the significance of the AEC-Q200 rating on the Stackpole part?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability for automotive applications. The RMCF2512FT2M15 carries this certification, making it suitable for automotive-grade designs. The RC6432F2154CS does not list this certification but remains suitable for general industrial and consumer applications.

Q: Are the packaging formats interchangeable?

A: The RC6432F2154CS packaging format is not specified in the provided data. The RMCF2512FT2M15 is supplied in Tape & Reel (TR) format. If your assembly process requires a specific packaging format, verify compatibility with your procurement and manufacturing requirements before substitution.

Q: Do both parts have the same moisture sensitivity?

A: Yes. Both the RC6432F2154CS and RMCF2512FT2M15 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) identical resistance value and tolerance, (2) identical power rating, (3) identical package format (2512 Metric), (4) identical composition (thick film), (5) identical operating temperature range, (6) identical temperature coefficient, (7) equivalent RoHS and REACH compliance status, and (8) compatible physical dimensions within PCB assembly tolerances.

Q: Can these parts be used in high-reliability applications?

A: Both parts meet ROHS3 compliance and carry MSL 1 ratings. The RMCF2512FT2M15 includes AEC-Q200 automotive qualification, which provides additional reliability assurance. For applications requiring specific reliability certifications beyond those listed, consult detailed component datasheets and application requirements.
