Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F14R7CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (14.7 Ohms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must match or exceed the original specification.

Mechanical Compatibility: Package designation (2512 / 6432 Metric) and number of terminations (2) must be identical. Physical dimensions and height must be compatible with the original footprint.

Compliance & Environmental: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are required. REACH status must be equivalent or unaffected.

Product Status: Only active production parts qualify as substitutes.

The CRCW251214R7FKEG from Vishay Dale meets all substitution criteria and is classified as an equivalent substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F14R7CS and CRCW251214R7FKEG are active production components with identical electrical specifications and package designations. Selection between these parts is based on the following factors:

Compliance Requirements: The CRCW251214R7FKEG carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability standards. The RC6432F14R7CS features moisture resistance without automotive qualification.

Packaging Format: The RC6432F14R7CS is supplied in standard packaging, while the CRCW251214R7FKEG is available in Tape & Reel (TR) format, which is preferred for automated assembly processes.

Inventory Availability: The CRCW251214R7FKEG has higher inventory availability (4542 pieces) compared to the RC6432F14R7CS (827 pieces).

Dimensional Tolerance: Both parts meet 2512 package specifications. The CRCW251214R7FKEG has a maximum seated height of 0.028" (0.70mm) versus 0.026" (0.66mm) for the RC6432F14R7CS. This 0.04mm difference is within standard PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251214R7FKEG directly replace the RC6432F14R7CS in existing designs?

A: Yes. Both parts share identical electrical specifications (14.7 Ohms ±1%, 1W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and package designation (2512 / 6432 Metric). The dimensional difference of 0.04mm in seated height is within standard PCB assembly tolerances and does not affect functionality or mechanical fit.

Q: What is the significance of AEC-Q200 qualification on the CRCW251214R7FKEG?

A: AEC-Q200 is an automotive industry standard for passive components. This qualification indicates the part has undergone rigorous testing for automotive applications. If your application requires automotive-grade reliability, the CRCW251214R7FKEG is the appropriate choice. The RC6432F14R7CS does not carry this qualification.

Q: Are there differences in moisture resistance between these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating equivalent moisture resistance performance. The RC6432F14R7CS explicitly lists moisture resistance as a feature, while the CRCW251214R7FKEG achieves the same MSL rating through its thick film composition and automotive qualification.

Q: Why is the CRCW251214R7FKEG supplied in Tape & Reel format?

A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly. This format enables high-speed pick-and-place machine compatibility, reducing assembly costs and improving production efficiency for volume manufacturing.

Q: Do both parts meet RoHS3 and REACH compliance?

A: Yes. Both the RC6432F14R7CS and CRCW251214R7FKEG are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the temperature coefficient specification, and why does it matter?

A: Both parts have a temperature coefficient of ±100ppm/°C, meaning the resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. This specification is critical for precision circuits where resistance stability across temperature variations is required.
