Substitute Part Grouping Explanation

Equivalent and substitute parts for the RC6432F754CS are determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 750 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical specifications. Additional features such as automotive AEC-Q200 certification represent enhanced qualifications that do not disqualify a part from substitution but indicate suitability for more demanding applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, General Applications): The RC6432F754CS remains the preferred choice for applications where Samsung Electro-Mechanics supply chain is established and inventory is available.

Upgrade Path (Active Status, Enhanced Certification): The AC2512FK-07750KL (YAGEO) and CRCW2512750KFKEG (Vishay Dale) are direct substitutes with Active product status. Both components include AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components or equivalent performance standards. These parts are electrically and mechanically interchangeable with the RC6432F754CS.

Alternative Selection (Legacy Status): The ERJ-1TNF7503U (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies and should not be selected for new product development.

Compliance Verification: All listed parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature ranges, ensuring regulatory and environmental compatibility across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07750KL be used as a direct replacement for RC6432F754CS?

A: Yes. The AC2512FK-07750KL meets all electrical specifications (750 kOhms ±1%, 1W) and mechanical requirements (2512 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range). Both components are ROHS3 compliant with MSL 1 rating. The YAGEO part includes AEC-Q200 certification, which does not prevent substitution but indicates enhanced automotive qualification.

Q: What is the difference between the RC6432F754CS and CRCW2512750KFKEG?

A: Both parts are functionally equivalent with identical electrical parameters and 2512 package specifications. The primary differences are manufacturer (Samsung vs. Vishay Dale) and the inclusion of AEC-Q200 automotive certification on the Vishay part. Physical dimensions show minor variations within tolerance: RC6432F754CS is 0.248" L x 0.126" W with 0.026" max height; CRCW2512750KFKEG is 0.248" L x 0.124" W with 0.028" max height. These dimensional differences do not affect PCB layout compatibility.

Q: Why is ERJ-1TNF7503U marked "Not For New Designs"?

A: The ERJ-1TNF7503U carries legacy product status from Panasonic Electronic Components. This designation indicates the manufacturer is not actively developing or promoting this part for new applications. The component remains electrically and mechanically suitable for replacement in existing designs but should not be selected for new product development. For new designs, AC2512FK-07750KL or CRCW2512750KFKEG are recommended.

Q: Are there packaging differences between these substitutes?

A: The RC6432F754CS is supplied in standard packaging (not specified as Tape & Reel). The AC2512FK-07750KL, CRCW2512750KFKEG, and ERJ-1TNF7503U are all supplied in Tape & Reel (TR) packaging. This difference affects handling and assembly processes but does not impact electrical or mechanical performance. Confirm packaging requirements with your procurement and assembly processes before substitution.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All listed parts, including RC6432F754CS, AC2512FK-07750KL, CRCW2512750KFKEG, and ERJ-1TNF7503U, carry MSL 1 (Unlimited) rating. This indicates no moisture sensitivity restrictions and no special storage or handling requirements.

Q: Can these parts be used interchangeably in automotive applications?

A: The AC2512FK-07750KL and CRCW2512750KFKEG include AEC-Q200 automotive certification and are suitable for automotive applications. The RC6432F754CS and ERJ-1TNF7503U do not specify AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, select AC2512FK-07750KL or CRCW2512750KFKEG.
