RC6432F2610CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2610CS is a 261 Ohms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and maintains ROHS3 compliance with MSL 1 rating. The part is currently in active production status with 700 pieces available in new original inventory. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2610CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (261 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 format (2512 / 6432 Metric), physical dimensions (0.248" L x 0.126" W maximum), and termination count (2) ensure physical interchangeability on printed circuit boards.

Compliance & Environmental: ROHS3 compliance, MSL 1 rating, and thick film composition are required attributes. Substitute parts must maintain equivalent environmental and regulatory standing.

The CRCW2512261RFKEG from Vishay Dale meets all substitution criteria through identical electrical and mechanical specifications, with the addition of AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F2610CS and CRCW2512261RFKEG are active production components with ROHS3 compliance and MSL 1 ratings, confirming suitability for general industrial and commercial applications. The CRCW2512261RFKEG carries additional AEC-Q200 automotive qualification, which extends its applicability to automotive-grade circuit designs without compromising compatibility with standard industrial applications. Selection between these parts should be based on application requirements: the Samsung component for standard industrial use, or the Vishay Dale component when automotive-grade reliability standards are specified or anticipated for future design revisions.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512261RFKEG replace the RC6432F2610CS in existing designs?

A: Yes. Both components share identical electrical specifications (261 Ohms ±1%, 1W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package format (2512 / 6432 Metric). Physical dimensions are within acceptable tolerance for PCB footprint compatibility.

Q: What is the significance of AEC-Q200 certification on the Vishay part?

A: AEC-Q200 is an automotive industry qualification standard. The CRCW2512261RFKEG meets enhanced reliability and testing requirements for automotive applications. This certification does not restrict use in non-automotive applications.

Q: Are there packaging differences between these parts?

A: The RC6432F2610CS is supplied in standard packaging, while the CRCW2512261RFKEG is supplied in Tape & Reel (TR) format. Both are compatible with standard pick-and-place assembly equipment. Tape & Reel packaging is standard for high-volume manufacturing.

Q: Do the slight dimensional variations affect PCB compatibility?

A: No. Width variation (3.20mm vs 3.15mm) and height variation (0.66mm vs 0.70mm) are within standard PCB footprint tolerances for the 2512 package. Both components are mechanically interchangeable.

Q: What is MSL 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture-controlled storage requirements. Both components can be stored under standard industrial conditions without special handling.
