Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW1206348RFKEB is determined by the following critical parameters:

Direct Equivalents maintain identical electrical specifications: 348 Ohms resistance, ±1% tolerance, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. These parts are interchangeable without circuit redesign.

Functional Equivalents share the same resistance, tolerance, package, temperature coefficient, operating range, and automotive rating but originate from different manufacturers. Mechanical dimensions (height) may vary within acceptable limits for PCB assembly.

Upgrade Substitutes provide enhanced performance characteristics while maintaining core electrical parameters. These include higher power ratings (0.5W instead of 0.25W) or specialized features such as pulse withstanding or high voltage capability. Upgrades are suitable when application requirements exceed the original specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: CRCW1206348RFKEA (Vishay Dale) is the primary equivalent, offering identical electrical and mechanical specifications with higher inventory availability (17,228 units). Both parts share the same manufacturer series (CRCW) and active product status.

For Cross-Manufacturer Substitution: RMCF1206FT348R (Stackpole Electronics Inc) and KTR18EZPF3480 (Rohm Semiconductor) provide functionally equivalent performance with active product status and full AEC-Q200 compliance. These options support supply chain diversification while maintaining electrical compatibility.

For Legacy System Support: ERJ-8ENF3480V (Panasonic Electronic Components) remains available with substantial inventory (91,569 units) but carries "Not For New Designs" status. This part is suitable only for maintenance, repair, and operations (MRO) applications or existing production lines requiring continuity.

For Enhanced Performance: ESR18EZPF3480 (Rohm Semiconductor) provides doubled power rating (0.5W vs. 0.25W) with pulse withstanding capability while maintaining all other electrical parameters. This upgrade is appropriate for applications requiring higher thermal margin or transient pulse immunity.

For High Voltage Applications: KTR18EZPF3480 (Rohm Semiconductor) incorporates high voltage thick film technology, suitable for circuits operating at elevated voltage levels while preserving the 0.25W power rating and standard package dimensions.

All recommended substitutes maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206348RFKEA be used as a direct replacement for CRCW1206348RFKEB?

A: Yes. Both parts are manufactured by Vishay Dale within the CRCW series, share identical electrical specifications (348 Ω, ±1%, 0.25W), operate across -55°C to 155°C, and carry AEC-Q200 automotive qualification. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the main part and KTR18EZPF3480?

A: Both maintain 348 Ω resistance, ±1% tolerance, 0.25W power rating, and 1206 package. KTR18EZPF3480 incorporates high voltage thick film technology and is manufactured by Rohm Semiconductor rather than Vishay Dale. The height specification differs slightly (0.026" vs. 0.024"), which remains within standard PCB assembly tolerances.

Q: Why is ERJ-8ENF3480V marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While functionally equivalent and suitable for existing applications, Panasonic recommends new designs utilize alternative sources. The part remains available for MRO and legacy system support.

Q: Can ESR18EZPF3480 replace CRCW1206348RFKEB in any application?

A: ESR18EZPF3480 is electrically compatible and physically fits the same footprint. The doubled power rating (0.5W vs. 0.25W) provides additional thermal margin. However, circuit design must accommodate the higher power dissipation capability. This part is suitable as a direct replacement in all applications where the original 0.25W rating is adequate.

Q: Are there package compatibility concerns when substituting between manufacturers?

A: All listed substitutes use the 1206 (3216 Metric) package. Height variations range from 0.024" to 0.028" (0.60mm to 0.70mm), which fall within standard PCB assembly specifications. No design modifications are required for package compatibility.

Q: Do all substitute parts maintain automotive AEC-Q200 qualification?

A: Yes. All listed equivalents and substitutes carry AEC-Q200 automotive qualification, ensuring compliance with automotive reliability and quality standards across the full operating temperature range of -55°C to 155°C.
