Key Parameters

Substitute Part Grouping Explanation

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

• Resistance Value: 75 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria. Dimensional variations within supplier tolerances and differences in product status or certifications (such as automotive AEC-Q200 qualification) do not preclude substitution but are noted for application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status)

RC2512FK-0775KL (YAGEO), CRCW251275K0FKEG (Vishay Dale), and RMCF2512FT75K0 (Stackpole) are all active products with full electrical and environmental specification equivalence to the RC6432F753CS. These parts are suitable for new designs and ongoing production applications.

Secondary Substitute (Legacy Status)

ERJ-1TNF7502U (Panasonic) meets all electrical and environmental specifications but carries a "Not For New Designs" product status. This part is suitable for replacement in existing applications or legacy system maintenance only.

Automotive Applications

CRCW251275K0FKEG (Vishay Dale), ERJ-1TNF7502U (Panasonic), and RMCF2512FT75K0 (Stackpole) include AEC-Q200 automotive qualification. The RC6432F753CS (Samsung) and RC2512FK-0775KL (YAGEO) do not specify automotive certification. Selection between qualified and non-qualified parts depends on application requirements.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0775KL replace RC6432F753CS directly?

A: Yes. Both parts share identical electrical specifications (75 kOhms ±1%, 1W), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), package (2512), and compliance ratings (ROHS3, MSL 1). Dimensional variations are within supplier tolerances.

Q: What is the difference between the Samsung and YAGEO parts?

A: RC6432F753CS and RC2512FK-0775KL are electrically and environmentally equivalent. Differences exist only in manufacturer, series designation (RC vs. RC_L), packaging format (not specified vs. Tape & Reel), and minor dimensional tolerances. Neither specifies automotive qualification.

Q: Why do some substitutes have AEC-Q200 certification?

A: CRCW251275K0FKEG (Vishay Dale), ERJ-1TNF7502U (Panasonic), and RMCF2512FT75K0 (Stackpole) are qualified to automotive standards. The RC6432F753CS does not specify this certification. AEC-Q200 qualification is required only for automotive applications; general industrial and consumer applications do not require this rating.

Q: Is ERJ-1TNF7502U suitable for new designs?

A: ERJ-1TNF7502U carries a "Not For New Designs" status. It is suitable for replacement in existing systems or legacy applications but should not be selected for new product development. Use RC2512FK-0775KL, CRCW251275K0FKEG, or RMCF2512FT75K0 for new designs.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within supplier tolerances. All parts conform to the 2512 (6432 Metric) package standard. Length ranges from 0.248" to 0.252" (6.30mm to 6.40mm), width from 0.122" to 0.126" (3.10mm to 3.20mm), and height from 0.026" to 0.028" (0.65mm to 0.70mm). These variations do not affect PCB layout or assembly compatibility.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts share this rating.

Q: Can I use these parts interchangeably in tape and reel format?

A: RC2512FK-0775KL, CRCW251275K0FKEG, ERJ-1TNF7502U, and RMCF2512FT75K0 are all supplied in Tape & Reel format. The RC6432F753CS packaging format is not specified. Verify packaging requirements for your assembly process before selection.
