Substitute Part Grouping Explanation

Substitute parts for the RC6432F17R8CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 17.8 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitutes meet these core parameters and are therefore electrically and mechanically interchangeable with the RC6432F17R8CS in standard applications.

Parameter Comparison

Engineering Selection Recommendations

CRCW251217R8FKEG (Vishay Dale) is the primary substitute for the RC6432F17R8CS. Both parts are in active production status and meet all electrical, mechanical, and compliance requirements. The Vishay Dale part includes AEC-Q200 automotive qualification, which provides additional reliability assurance for demanding applications. Inventory availability is higher at 1723 units.

ERJ-1TNF17R8U (Panasonic Electronic Components) is a functional equivalent with identical electrical and mechanical specifications. However, this part carries a "Not For New Designs" status, indicating it is in mature or declining production phase. The Panasonic part also includes AEC-Q200 automotive qualification. This substitute is suitable for legacy system maintenance and repair applications where existing design validation has been completed. Inventory availability is highest at 5043 units.

For new design implementations, CRCW251217R8FKEG is the recommended substitute due to active production status. For existing systems or repair applications, ERJ-1TNF17R8U remains functionally equivalent despite its mature status.

Frequently Asked Questions (FAQ)

Q: Can CRCW251217R8FKEG be used as a direct replacement for RC6432F17R8CS?

A: Yes. Both parts share identical electrical specifications (17.8 Ohms ±1%, 1W), operate across the same temperature range (-55°C ~ 155°C), use the same 2512 package, and meet ROHS3 compliance with MSL 1 rating. Physical dimensions are equivalent within manufacturing tolerances.

Q: What is the difference between the Samsung and Vishay Dale parts?

A: The RC6432F17R8CS (Samsung) features moisture-resistant thick film construction. The CRCW251217R8FKEG (Vishay Dale) provides the same electrical performance with added AEC-Q200 automotive qualification. Both are active production parts with identical core specifications.

Q: Why is the Panasonic ERJ-1TNF17R8U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase and may be subject to discontinuation. While it remains functionally equivalent and suitable for repair or legacy applications, new designs should prioritize active production alternatives such as CRCW251217R8FKEG.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use the 2512 (6432 Metric) package with identical termination count (2) and compatible physical dimensions. PCB footprints and assembly processes remain unchanged.

Q: Do all substitutes meet the same environmental and compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and operate across -55°C ~ 155°C. The Vishay Dale and Panasonic parts include additional AEC-Q200 automotive qualification.

Q: Which substitute offers the best inventory availability?

A: ERJ-1TNF17R8U (Panasonic) has the highest inventory at 5043 units, followed by CRCW251217R8FKEG (Vishay Dale) at 1723 units. For active production requirements, CRCW251217R8FKEG is recommended despite lower inventory due to its active status.
