Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F755CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 7.5 MOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match or wider range acceptable)

Mechanical Equivalence Requirements:

• Package format: 2512 (6432 Metric) (exact match)
• Physical dimensions: 6.30mm length, compatible width and height within standard tolerances
• Termination count: 2 (exact match)

Material & Composition Requirements:

• Composition: Thick Film (exact match)

Compliance Requirements:

• RoHS compliance status: ROHS3 or equivalent
• Moisture sensitivity: MSL 1 or lower (more stringent acceptable)

The CRCW25127M50FKEG from Vishay Dale meets all substitution criteria and is classified as an equivalent part for the RC6432F755CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: RC6432F755CS

• Active production status with established supply (1164 units in stock)
• ROHS3 compliant with MSL 1 rating
• Moisture-resistant thick film construction
• Suitable for general industrial applications

Substitute Part: CRCW25127M50FKEG

• Active production status with higher inventory availability (2491 units in stock)
• ROHS3 compliant with MSL 1 rating
• Automotive AEC-Q200 qualified thick film construction
• Suitable for automotive and high-reliability applications
• Mechanical dimensions within acceptable PCB layout tolerances (width variance: 0.05mm, height variance: 0.04mm)

Both parts satisfy identical electrical specifications and environmental operating conditions. Selection between the two should be based on supply availability, packaging format requirements (Cut Tape & Digi-Reel vs. standard packaging), and application-specific qualification needs. The Vishay Dale part offers automotive-grade certification, which may be required for certain end-use applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW25127M50FKEG be used as a direct replacement for RC6432F755CS on existing PCBs?

A: Yes. Both parts share identical electrical specifications (7.5 MOhms, ±1%, 1W, ±100ppm/°C) and operate across the same temperature range (-55°C to 155°C). Mechanical dimensions are compatible within standard PCB layout tolerances. The width difference of 0.05mm and height difference of 0.04mm fall within acceptable manufacturing tolerances for 2512 package components.

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

A: AEC-Q200 is an automotive industry standard qualification for passive components. This certification indicates the part has undergone additional reliability testing and is suitable for automotive applications. If your application does not require automotive qualification, this does not affect substitutability for general industrial use.

Q: Are there any differences in moisture handling between these two parts?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating they can be stored and handled without moisture-related constraints. No difference exists in moisture performance between the two parts.

Q: What packaging formats are available for each part?

A: The RC6432F755CS is available in standard packaging. The CRCW25127M50FKEG is supplied in Cut Tape (CT) and Digi-Reel® formats, which may affect procurement and assembly processes depending on your production requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both RC6432F755CS and CRCW25127M50FKEG are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What is the practical difference between the ±100ppm/°C temperature coefficient for both parts?

A: The temperature coefficient of ±100ppm/°C is identical for both parts. This means the resistance value will change by a maximum of 100 parts per million for every degree Celsius change in operating temperature. No practical difference exists between the two parts in this specification.
