Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CRCW1206348RFKEBC are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Number of Terminations: 2

Power Rating Consideration: Substitute parts may have equal or higher power ratings (0.25W or greater) while maintaining identical physical dimensions and electrical characteristics. Higher power ratings do not affect circuit compatibility when all other parameters remain constant.

Compliance Parameters (Must Match):

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

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the CRCW1206348RFKEBC. Selection between alternatives is based on the following factors:

ESR18EZPF3480 (Rohm Semiconductor):

• Higher power rating (0.5W vs. 0.25W) provides additional thermal margin in applications with power dissipation concerns
• AEC-Q200 automotive qualification available
• Pulse withstanding capability specified

KTR18EZPF3480 (Rohm Semiconductor):

• Matched power rating (0.25W) to the original part
• AEC-Q200 automotive qualification available
• High voltage capability specified

All three parts are Active status products with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and environmental regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can ESR18EZPF3480 be used as a direct replacement for CRCW1206348RFKEBC?

A: Yes. The ESR18EZPF3480 maintains identical resistance (348 Ohms), tolerance (±1%), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.5W vs. 0.25W) does not affect compatibility and provides additional thermal capability.

Q: Can KTR18EZPF3480 be used as a direct replacement for CRCW1206348RFKEBC?

A: Yes. The KTR18EZPF3480 is electrically and mechanically identical to the CRCW1206348RFKEBC, with matching power rating (0.25W), resistance value, tolerance, package dimensions, and operating specifications.

Q: What is the significance of the AEC-Q200 rating on the substitute parts?

A: AEC-Q200 is an automotive qualification standard. Both substitute parts carry this certification, indicating suitability for automotive applications. The original CRCW1206348RFKEBC does not specify this rating.

Q: Are there dimensional differences between the main part and substitutes?

A: Slight dimensional variations exist within tolerance. The CRCW1206348RFKEBC measures 0.120" L x 0.061" W (3.05mm x 1.55mm), while both substitutes measure 0.126" L x 0.063" W (3.20mm x 1.60mm). Both are within 1206 package specification and maintain identical height (0.026" maximum seated height). These variations do not affect PCB footprint compatibility.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For standard applications matching the original 0.25W specification, KTR18EZPF3480 provides direct equivalence. For applications requiring higher thermal margin or automotive qualification, ESR18EZPF3480 offers enhanced capability while maintaining full compatibility.

Q: Are all parts RoHS3 compliant?

A: Yes. The CRCW1206348RFKEBC and both substitute parts (ESR18EZPF3480 and KTR18EZPF3480) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
