Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F6191CS is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 6.19 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film

Important Parameters (Must Match or Exceed):

• Temperature coefficient: ±100 ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum
• Moisture sensitivity level: MSL 1 or equivalent
• RoHS compliance: ROHS3 or equivalent

The two substitute parts identified—CRCW25126K19FKEG (Vishay Dale) and ERJ-1TNF6191U (Panasonic Electronic Components)—satisfy all critical and important parameters. Both parts maintain identical electrical specifications and package dimensions within acceptable mechanical tolerances. The primary distinction between substitutes relates to product status and automotive qualification ratings.

Engineering Selection Recommendations

Primary Substitute: CRCW25126K19FKEG (Vishay Dale)

The CRCW25126K19FKEG is the preferred substitute for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and manufacturer support. The component carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Dimensional variations are minimal and fall within standard PCB assembly tolerances. The part is available in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Secondary Substitute: ERJ-1TNF6191U (Panasonic Electronic Components)

The ERJ-1TNF6191U is classified as Not For New Designs, indicating Panasonic has discontinued active development for this part number. While the component maintains full electrical and mechanical compatibility, its use is restricted to legacy system maintenance, repair, and obsolescence management. The part carries AEC-Q200 automotive qualification. Existing inventory of 2809 pieces is available, but future procurement should not rely on this part for new product development.

Selection Criteria:

• For new designs: Use CRCW25126K19FKEG
• For legacy system support: ERJ-1TNF6191U remains compatible
• For automotive applications: Both substitutes carry AEC-Q200 qualification
• For general industrial use: All three parts are functionally equivalent

Frequently Asked Questions (FAQ)

Q: Can CRCW25126K19FKEG be used as a direct replacement for RC6432F6191CS?

A: Yes. Both parts share identical electrical specifications (6.19 kOhms, ±1%, 1W), composition (thick film), and package designation (2512/6432 Metric). Dimensional differences are within standard PCB assembly tolerances. No circuit redesign is required.

Q: What is the difference between the RC6432F6191CS and CRCW25126K19FKEG?

A: The primary differences are manufacturer (Samsung vs. Vishay Dale) and automotive qualification (CRCW25126K19FKEG carries AEC-Q200 rating). Electrical performance is identical. The Vishay part has slightly different dimensional tolerances (width 3.15mm vs. 3.20mm, height 0.70mm vs. 0.66mm), which are acceptable for standard PCB assembly.

Q: Why is ERJ-1TNF6191U marked as "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this part to end-of-life status. While existing inventory is available and the part remains fully functional, Panasonic no longer actively supports new product designs using this component. New designs should specify CRCW25126K19FKEG or equivalent active-status alternatives.

Q: Are there any compatibility issues with PCB assembly equipment?

A: No. All three parts use the 2512 (6432 Metric) package standard. Dimensional variations are minor and within industry-standard PCB assembly tolerances. No equipment recalibration or process modification is required when switching between these parts.

Q: Does the AEC-Q200 rating on CRCW25126K19FKEG affect non-automotive applications?

A: No. AEC-Q200 qualification indicates the part meets automotive reliability standards. This certification does not restrict use in non-automotive applications and provides additional assurance of component quality and reliability.

Q: What is the moisture sensitivity level, and why does it matter?

A: All three parts carry MSL 1 (Unlimited), meaning they have no moisture sensitivity restrictions. These components can be stored indefinitely without special humidity controls and do not require baking before soldering.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, provided the assembly uses standard 2512 package footprints. The electrical performance is identical across all three parts. Physical dimensions are within acceptable tolerances for standard PCB designs.
