Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F61R9CS are qualified based on the following critical parameters:

Electrical Specifications: Resistance value of 61.9 Ohms, tolerance of ±1%, and power rating of 1W must be identical across all substitutes.

Package Compatibility: All substitutes must use the 2512 (6432 Metric) package to ensure mechanical fit and thermal performance equivalence in PCB layouts.

Thermal Characteristics: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Compliance Requirements: ROHS3 compliance and MSL 1 rating are mandatory for environmental and handling consistency.

Composition: Thick film construction ensures consistent performance characteristics across substitutes.

The following parts meet these substitution criteria:

1. CRCW251261R9FKEG (Vishay Dale) – Active product with automotive AEC-Q200 qualification
2. ERJ-1TNF61R9U (Panasonic Electronic Components) – Not For New Designs status with automotive AEC-Q200 qualification

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW251261R9FKEG (Vishay Dale) is the recommended substitute for new designs. This part maintains Active product status, ensuring long-term availability and supply chain stability. The automotive AEC-Q200 qualification provides additional reliability assurance for demanding applications. Electrical and thermal parameters are identical to the RC6432F61R9CS, with mechanical dimensions within acceptable tolerance for direct PCB substitution.

Secondary Substitute: ERJ-1TNF61R9U (Panasonic Electronic Components) is functionally equivalent but carries a Not For New Designs designation. This status indicates the manufacturer is phasing out this product line. Use of this part is limited to legacy system maintenance or applications where existing inventory must be consumed. The automotive AEC-Q200 qualification and identical electrical specifications support functional interchangeability in existing designs.

Compliance Alignment: All three parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental consistency across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can CRCW251261R9FKEG be used as a direct replacement for RC6432F61R9CS?

A: Yes. Both parts share identical electrical specifications (61.9 Ohms ±1%, 1W), thermal characteristics (±100ppm/°C, -55°C to 155°C), and package dimensions (2512/6432 Metric). Mechanical fit and electrical performance are equivalent.

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

A: The primary difference is manufacturer and packaging format. The RC6432F61R9CS uses standard packaging, while CRCW251261R9FKEG is supplied in Tape & Reel format. The Vishay part includes automotive AEC-Q200 qualification, which is not specified for the Samsung part. All electrical and thermal parameters are identical.

Q: Why is ERJ-1TNF61R9U marked as Not For New Designs?

A: This designation indicates Panasonic is discontinuing this product line. While the part remains functionally equivalent and available in current inventory, it is not recommended for new circuit designs due to uncertain future availability. Use this part only for legacy system support or existing design maintenance.

Q: Are there dimensional differences between these substitutes?

A: Minor dimensional variations exist within acceptable tolerances. The RC6432F61R9CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with 0.026" max height. CRCW251261R9FKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm) with 0.028" max height. ERJ-1TNF61R9U measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with 0.028" max height. These variations do not affect PCB layout compatibility or thermal performance.

Q: Do all substitutes maintain the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Handling, storage, and reflow processes are identical across all substitutes.

Q: Which part should be selected for automotive applications?

A: Both CRCW251261R9FKEG and ERJ-1TNF61R9U carry automotive AEC-Q200 qualification. For new automotive designs, CRCW251261R9FKEG is the preferred choice due to Active product status. For existing automotive systems, ERJ-1TNF61R9U remains functionally qualified despite its Not For New Designs designation.
