Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2741CS is determined by strict matching of the following parameters:

Mandatory Matching Parameters:

• Resistance value: 2.74 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture Sensitivity Level: MSL 1
• RoHS Status: ROHS3 Compliant

Acceptable Variations:

• Manufacturer identity (different suppliers)
• Packaging format (Tape & Reel vs. other formats)
• Physical dimensions within 2512 package tolerance
• Product status (Active or Not For New Designs)
• Additional certifications (AEC-Q200 automotive qualification)

The three substitute parts identified—RC2512FK-072K74L (YAGEO), CRCW25122K74FKEG (Vishay Dale), and ERJ-1TNF2741U (Panasonic Electronic Components)—meet all mandatory matching criteria and are therefore electrically and mechanically interchangeable with the primary part.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: RC2512FK-072K74L (YAGEO) is the preferred substitute. This part maintains Active product status, ensuring long-term availability and manufacturer support. It provides the highest inventory level (7962 pieces) among substitute options and is packaged in Tape & Reel format suitable for automated assembly processes.

For Automotive Applications: CRCW25122K74FKEG (Vishay Dale) or ERJ-1TNF2741U (Panasonic Electronic Components) are suitable when AEC-Q200 automotive qualification is required. Both parts carry this certification, meeting automotive industry reliability standards. CRCW25122K74FKEG maintains Active status, while ERJ-1TNF2741U is marked Not For New Designs.

For New Design Initiation: Avoid ERJ-1TNF2741U (Panasonic) due to its Not For New Designs status. This designation indicates the manufacturer is phasing out this part number. Select either RC2512FK-072K74L or CRCW25122K74FKEG for designs requiring long-term production support.

For Supply Chain Continuity: All three substitute parts are currently in stock with substantial inventory levels. Selection among them should prioritize the primary supplier relationship and packaging requirements of the manufacturing process.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-072K74L be used as a direct replacement for RC6432F2741CS?

A: Yes. Both parts share identical electrical specifications (2.74 kOhms, ±1%, 1W), operate across the same temperature range (-55°C to 155°C), use thick film composition, and are packaged in the 2512 (6432 Metric) format. Physical dimensions are within acceptable tolerance for the package type. The parts are electrically and mechanically interchangeable.

Q: What is the difference between the Samsung and YAGEO versions?

A: The primary differences are manufacturer identity and packaging format. RC6432F2741CS is supplied by Samsung Electro-Mechanics, while RC2512FK-072K74L is supplied by YAGEO. Both maintain identical electrical and thermal characteristics. YAGEO offers higher inventory availability (7962 vs. 902 pieces).

Q: Why is ERJ-1TNF2741U marked "Not For New Designs"?

A: This designation indicates that Panasonic Electronic Components is discontinuing this part number. While the part remains functionally equivalent and is currently in stock (7193 pieces), it should not be selected for new product designs due to uncertain long-term availability. Use RC2512FK-072K74L or CRCW25122K74FKEG for new designs.

Q: Are the Vishay Dale and Panasonic parts suitable for automotive applications?

A: Yes. Both CRCW25122K74FKEG (Vishay Dale) and ERJ-1TNF2741U (Panasonic) carry AEC-Q200 automotive qualification. These parts meet automotive industry reliability and performance standards. The Samsung and YAGEO versions do not specify automotive certification.

Q: What are the physical dimension differences between substitute parts?

A: All parts conform to the 2512 (6432 Metric) package specification. Minor variations exist within tolerance: Samsung measures 6.30mm × 3.20mm, YAGEO measures 6.35mm × 3.10mm, Vishay measures 6.30mm × 3.15mm, and Panasonic measures 6.40mm × 3.20mm. These variations are within standard package tolerance and do not affect PCB footprint compatibility.

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

A: Yes. All substitute parts are electrically identical and use the same 2512 package footprint. However, manufacturing best practices typically specify a single part number per assembly to maintain traceability and simplify quality control documentation.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts require no special moisture control during storage or handling. They can be stored in standard warehouse conditions without desiccant packaging or humidity-controlled environments, simplifying logistics and reducing storage costs.
