Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FKR240 is determined by strict equivalence across the following parameters:

• Resistance value: 240 mOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package format: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 or equivalent
• Moisture sensitivity: MSL 1 or better

The RCWE1206R240FKEA from Vishay Dale meets all electrical and mechanical substitution criteria. Both parts share identical resistance, tolerance, power rating, temperature coefficient, and operating range. Package dimensions are within acceptable mechanical tolerances for 1206 form factor components. Both maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The RCWE1206R240FKEA qualifies as a direct electrical and mechanical substitute for the CSR1206FKR240. Both components satisfy identical electrical specifications: 240 mOhms resistance at ±1% tolerance, 0.5W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Mechanical compatibility is confirmed through standard 1206 package format with dimensions within acceptable tolerances for surface mount assembly. Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring equivalent environmental and regulatory performance. The Vishay Dale part includes additional AEC-Q200 automotive qualification and moisture-resistant features, providing enhanced reliability for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can the RCWE1206R240FKEA replace the CSR1206FKR240 in existing designs?

A: Yes. Both parts meet identical electrical specifications (240 mOhms ±1%, 0.5W, ±100ppm/°C, -55°C to 155°C) and use the same 1206 package format. Mechanical dimensions are within standard tolerances for 1206 components.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within 1206 package tolerances. The Stackpole part measures 0.120" × 0.061" × 0.026" maximum height; the Vishay Dale part measures 0.122" × 0.063" × 0.028" maximum height. These differences are within acceptable limits for standard PCB assembly processes.

Q: Do both parts have equivalent compliance certifications?

A: Both parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. The Vishay Dale part includes additional AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What determines substitution eligibility for this resistor?

A: Substitution requires matching resistance value (240 mOhms), tolerance (±1%), power rating (0.5W minimum), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

Q: Can parts with different resistance values or tolerances substitute for the CSR1206FKR240?

A: No. Resistance value and tolerance are critical electrical parameters. Only parts rated 240 mOhms ±1% qualify as substitutes. Different values or tolerances represent different component specifications.
