RC6432F910CS Equivalent & Substitute Parts

Part Overview

The RC6432F910CS is a 91 Ohm ±1% 1W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This component is classified as Active product status and features moisture-resistant construction suitable for general industrial applications. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and package compatibility align with the main part. Alternative sources become necessary for supply chain continuity, inventory availability, or application-specific requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F910CS are qualified based on the following criteria:

Electrical Parameters:

• Resistance value: 91 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance & Environmental:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• Thick film composition

The identified substitutes meet all core electrical and mechanical requirements. Differences in product status, packaging format (Tape & Reel vs. bulk), and optional automotive qualification (AEC-Q200) are noted but do not prevent functional substitution in applications where these certifications are not mandated.

Parameter Comparison

Engineering Selection Recommendations

RC6432F910CS (Samsung Electro-Mechanics): Primary selection for general industrial applications. Active product status ensures continued manufacturer support and supply availability. Suitable for non-automotive applications requiring standard thick film resistor performance.

ERJ-1TNF91R0U (Panasonic Electronic Components): Functionally equivalent with AEC-Q200 automotive qualification. Product status is "Not For New Designs," indicating this part is in mature phase with limited future development. Use only when existing designs require Panasonic sourcing or when automotive qualification is required and legacy design continuity is necessary.

RMCF2512FT91R0 (Stackpole Electronics Inc): Functionally equivalent with AEC-Q200 automotive qualification and Active product status. Recommended for automotive applications or when Stackpole supply chain is preferred. Dimensions and electrical specifications are identical to the main part.

All three parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility in moisture-sensitive assembly environments without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF91R0U replace RC6432F910CS in a non-automotive application?

A: Yes. The ERJ-1TNF91R0U meets all electrical and mechanical specifications. The "Not For New Designs" status does not prevent substitution in existing designs; it indicates Panasonic will not develop new variants of this part. Verify component availability with your supplier before design implementation.

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

A: All three parts share identical electrical specifications (91 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C). The RC6432F910CS and RMCF2512FT91R0 are Active products. The ERJ-1TNF91R0U is Not For New Designs. The Panasonic and Stackpole parts include AEC-Q200 automotive qualification; the Samsung part does not specify this certification. Physical dimensions vary slightly in length (6.30mm vs. 6.40mm) and height (0.66mm vs. 0.70mm), but all conform to the 2512 package standard.

Q: Are there any height clearance concerns with the substitute parts?

A: The ERJ-1TNF91R0U and RMCF2512FT91R0 have maximum seated heights of 0.028" (0.70mm), compared to 0.026" (0.66mm) for the RC6432F910CS. In applications with tight vertical clearance constraints, verify that the additional 0.002" (0.04mm) height does not exceed design limits.

Q: Do all parts require the same moisture handling procedures?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), meaning they do not require special moisture control during storage, handling, or assembly. Standard component storage conditions are sufficient.

Q: Which part should be selected for a new automotive design?

A: For new automotive designs, either the RMCF2512FT91R0 (Stackpole, Active status) or ERJ-1TNF91R0U (Panasonic, Not For New Designs) can be used based on AEC-Q200 qualification. Stackpole is preferred due to Active product status, ensuring long-term availability and support.

Q: Are these parts interchangeable on the PCB without layout modifications?

A: Yes. All parts use the 2512 (6432 Metric) package with identical footprint and termination count (2). PCB layout modifications are not required. Minor height variations (0.002" maximum) do not affect standard assembly processes.
