Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW1206348KFKEAC is determined by the following mandatory parameters:

• Resistance value: 348 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical specifications. Additional certifications such as AEC-Q200 automotive qualification are available in certain substitute options but are not required for basic substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts are Active status components with full RoHS3 compliance and MSL 1 rating, making them electrically and mechanically interchangeable for standard applications.

KTR18EZPF3483 (Rohm Semiconductor) and RMCF1206FT348K (Stackpole Electronics) both carry AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability and qualification documentation.

CRCW1206348KFKEAC (Vishay Dale) is the primary reference part without automotive certification. Selection between these three parts should be based on supply availability, lead time, and whether AEC-Q200 certification is required by the application specification.

Frequently Asked Questions (FAQ)

Q: Can KTR18EZPF3483 or RMCF1206FT348K be used as direct replacements for CRCW1206348KFKEAC?

A: Yes. All three parts share identical electrical specifications (348 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package format (1206). They are mechanically and electrically interchangeable. The substitute parts include additional AEC-Q200 automotive certification, which does not prevent their use in non-automotive applications.

Q: What is the difference between the main part and substitute parts?

A: The primary difference is automotive qualification. KTR18EZPF3483 and RMCF1206FT348K are AEC-Q200 certified, while CRCW1206348KFKEAC does not specify this certification. All other electrical and mechanical parameters are identical.

Q: Are there dimensional differences between these parts?

A: Nominal dimensions are equivalent (1206 package). Minor variations exist in maximum seated height: CRCW1206348KFKEAC and KTR18EZPF3483 are 0.026" (0.65mm) maximum, while RMCF1206FT348K is 0.028" (0.70mm) maximum. These differences are within standard PCB assembly tolerances and do not affect interchangeability.

Q: Which part should be selected for automotive applications?

A: KTR18EZPF3483 or RMCF1206FT348K are appropriate for automotive applications due to AEC-Q200 certification. Selection between these two should be based on availability and lead time.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating, suitable for standard reflow soldering processes without moisture baking requirements.
