RC6432F2612CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F2612CS is a 26.1 kOhms ±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 a temperature coefficient of ±100ppm/°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative qualified sources while maintaining electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2612CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Resistance value: 26.1 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Non-Negotiable):

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compliance Parameters:

• RoHS3 compliance required
• MSL 1 rating required

The CRCW251226K1FKEG from Vishay Dale meets all electrical and mechanical equivalence criteria. This substitute maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The 2512 package format ensures PCB footprint compatibility. Both components are thick film construction with MSL 1 moisture sensitivity rating and ROHS3 compliance status.

Engineering Selection Recommendations

Primary Selection: RC6432F2612CS (Samsung Electro-Mechanics)

The RC6432F2612CS is the specified component and should be selected when available. This part is in active production status with 832 pieces currently in stock inventory. It carries ROHS3 compliance and REACH unaffected status, meeting all regulatory requirements for industrial and commercial applications.

Substitute Selection: CRCW251226K1FKEG (Vishay Dale)

The CRCW251226K1FKEG qualifies as a direct electrical and mechanical equivalent. This substitute maintains all critical electrical parameters: 26.1 kOhms resistance, ±1% tolerance, 1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The 2512 package format ensures PCB footprint compatibility with minimal dimensional variance (width difference of 0.002", height difference of 0.002"). Both components are thick film construction with identical MSL 1 moisture sensitivity and ROHS3 compliance.

The CRCW251226K1FKEG carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. This part is available in Tape & Reel packaging with 6273 pieces in current inventory.

Selection between these two parts should be based on availability, supply chain lead times, and application-specific requirements. Both parts are functionally interchangeable within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251226K1FKEG be used as a direct replacement for the RC6432F2612CS?

A: Yes. Both components share identical electrical specifications (26.1 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and are packaged in the 2512 (6432 Metric) format. Dimensional differences are minimal (0.002" width variance, 0.002" height variance) and do not affect PCB assembly or performance. Both are ROHS3 compliant with MSL 1 moisture sensitivity rating.

Q: Are there any package compatibility concerns between these two parts?

A: No. Both components use the 2512 (6432 Metric) package format with identical footprint specifications. The dimensional variations (length 6.30mm for both, width 6.30mm vs 6.30mm, height 0.66mm vs 0.70mm) fall within standard PCB assembly tolerances and do not require design modifications.

Q: What is the difference between the Samsung and Vishay Dale versions?

A: The primary difference is manufacturer and packaging format. The RC6432F2612CS is supplied by Samsung Electro-Mechanics with moisture-resistant thick film construction. The CRCW251226K1FKEG is supplied by Vishay Dale with automotive AEC-Q200 qualification and is available in Tape & Reel packaging. Electrical and mechanical specifications are identical.

Q: Does the AEC-Q200 rating on the Vishay part provide additional benefits?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. For non-automotive applications, this certification provides additional assurance of component quality and reliability but is not required. Both parts meet the same electrical and thermal specifications.

Q: What are the moisture sensitivity considerations for these parts?

A: Both components carry MSL 1 (Unlimited) moisture sensitivity rating, indicating they do not require special moisture control during storage or handling. Standard industrial storage conditions are acceptable for both parts.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both components are electrically and mechanically equivalent and carry identical compliance certifications (ROHS3, REACH unaffected, EAR99 ECCN). They can be used interchangeably in the same circuit design and production environment.
