Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1021CS is determined by strict alignment of the following parameters:

Electrical Parameters (Critical):

• Resistance value: 1.02 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Critical):

• Package format: 2512 (6432 Metric)
• Physical dimensions: 0.248" L x 0.126" W (6.30mm x 3.20mm)
• Number of terminations: 2

Compliance Parameters (Required):

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The RMCF2512FT1K02 from Stackpole Electronics Inc meets all critical electrical, mechanical, and compliance requirements. This component shares identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The package format and physical dimensions are equivalent. Both components maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

RC6432F1021CS (Samsung Electro-Mechanics):

• Primary selection for moisture-resistant applications
• Active product status with full inventory availability (896 Pcs)
• ROHS3 compliant with unlimited MSL rating
• Suitable for general industrial and consumer applications

RMCF2512FT1K02 (Stackpole Electronics Inc):

• Qualified substitute with automotive AEC-Q200 certification
• Active product status with comparable inventory (887 Pcs)
• ROHS3 compliant with unlimited MSL rating
• Appropriate for automotive and high-reliability applications requiring AEC-Q200 qualification
• Seated height specification of 0.028" (0.70mm) versus 0.026" (0.66mm) remains within acceptable mechanical tolerance for 2512 package format

Both components satisfy identical electrical specifications and mechanical requirements. Selection between them depends on application-specific compliance requirements. The Stackpole component provides additional automotive qualification where required by design specifications.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT1K02 directly replace RC6432F1021CS in existing designs?

A: Yes. Both components share identical electrical parameters (1.02 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), mechanical dimensions (2512 package, 0.248" L x 0.126" W), and compliance certifications (ROHS3, MSL 1). The seated height difference of 0.002" (0.04mm) is within standard PCB assembly tolerances for this package format.

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

A: AEC-Q200 is an automotive industry qualification standard. The RMCF2512FT1K02 meets this specification, making it suitable for automotive applications requiring documented reliability and quality assurance. The RC6432F1021CS does not carry this certification.

Q: Are there packaging differences between these parts?

A: The RC6432F1021CS is supplied in standard packaging format. The RMCF2512FT1K02 is specified as Cut Tape (CT) packaging. Both are compatible with standard PCB assembly processes. Verify packaging requirements with your procurement specifications.

Q: Do both parts meet environmental compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Both maintain MSL 1 (unlimited) moisture sensitivity level.

Q: What determines substitution eligibility for 2512 chip resistors?

A: Substitution requires matching of resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package format, physical dimensions, and compliance certifications. Seated height variations within standard package tolerances are acceptable. Composition (thick film) and termination count (2) must also align.
