Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F1400CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 140 Ohms, tolerance of ±1%, power rating of 1W, and temperature coefficient of ±100ppm/°C must be identical across all substitute candidates.

Mechanical Parameters: Package designation of 2512 (6432 Metric) with two terminations ensures physical and electrical compatibility with the original design footprint.

Environmental & Compliance Parameters: Operating temperature range of -55°C to 155°C, RoHS3 compliance, MSL rating of 1, and REACH unaffected status must be maintained.

Composition & Construction: Thick film construction is required for all substitutes.

The three identified substitute parts meet all these criteria and are therefore classified as direct equivalents suitable for component replacement.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain identical electrical and mechanical specifications to the RC6432F1400CS and are suitable for direct replacement in applications requiring a 140 Ohm 1% 1W 2512 chip resistor.

RC2512FK-07140RL (YAGEO): This part is supplied in Tape & Reel packaging and carries moisture-resistant features equivalent to the original. It maintains Active product status with 9043 pieces in inventory.

CRCW2512140RFKEG (Vishay Dale): This part includes AEC-Q200 automotive qualification in addition to the base specifications. It is supplied in Tape & Reel packaging with 80697 pieces in inventory, providing the highest stock availability among all substitutes.

RMCF2512FT140R (Stackpole Electronics Inc): This part includes AEC-Q200 automotive qualification and is supplied in Cut Tape packaging with 11705 pieces in inventory. The dimensional specifications match the original part precisely.

Selection between substitutes depends on packaging requirements (Tape & Reel versus Cut Tape), inventory availability, and whether automotive-grade qualification (AEC-Q200) is required for the application. All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07140RL be used as a direct replacement for RC6432F1400CS?

A: Yes. Both parts share identical resistance (140 Ohms), tolerance (±1%), power rating (1W), package format (2512), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, MSL 1).

Q: What is the difference between the YAGEO and Vishay Dale substitutes?

A: The primary difference is that CRCW2512140RFKEG includes AEC-Q200 automotive qualification, while RC2512FK-07140RL does not. Both maintain identical electrical specifications and package format. The Vishay part is supplied in Tape & Reel format with significantly higher inventory availability.

Q: Does the Stackpole RMCF2512FT140R include automotive qualification?

A: Yes. RMCF2512FT140R carries AEC-Q200 automotive qualification. It is supplied in Cut Tape packaging and maintains all electrical and mechanical specifications identical to the original RC6432F1400CS.

Q: Are there packaging differences between the substitute parts?

A: Yes. RC2512FK-07140RL and CRCW2512140RFKEG are supplied in Tape & Reel (TR) format, while RMCF2512FT140R is supplied in Cut Tape (CT) format. All three parts are compatible with the same PCB footprint and mounting equipment capable of handling 2512 package components.

Q: Do all substitute parts meet the same environmental compliance standards?

A: Yes. All three substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). They all operate across the identical temperature range of -55°C to 155°C.

Q: Which substitute part has the highest inventory availability?

A: CRCW2512140RFKEG (Vishay Dale) has 80697 pieces in stock, significantly higher than RC2512FK-07140RL (9043 pieces) and RMCF2512FT140R (11705 pieces).
