Substitute Part Grouping Explanation

Substitute parts for the CRCW1206348RFKEAC are qualified based on the following criteria:

• Identical resistance value: 348 Ohms
• Identical tolerance: ±1%
• Identical package: 1206 (3216 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

Substitute parts may differ in power rating, manufacturer, series designation, and automotive certifications. These differences do not affect substitution eligibility when the application power requirement does not exceed the substitute part's rating.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the CRCW1206348RFKEAC. Selection between alternatives is determined by application requirements:

ESR18EZPF3480 provides increased power dissipation capability at 0.5W (1/2W) rating with automotive AEC-Q200 qualification and pulse withstanding features. This substitute is suitable for applications requiring higher thermal margin or automotive-grade reliability.

KTR18EZPF3480 maintains the identical 0.25W (1/4W) power rating as the main part while offering automotive AEC-Q200 qualification and high voltage features. This substitute is appropriate for automotive applications or designs requiring high voltage performance without power rating changes.

All three parts are Active status products with RoHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and environmental regulation adherence.

Frequently Asked Questions (FAQ)

Q: Can ESR18EZPF3480 replace CRCW1206348RFKEAC in any circuit?

A: Yes. The ESR18EZPF3480 is electrically and mechanically compatible. The higher 0.5W power rating provides additional thermal margin and does not create incompatibility. The component will function identically in circuits designed for the 0.25W rated part.

Q: What is the difference between KTR18EZPF3480 and ESR18EZPF3480?

A: Both are Rohm Semiconductor products with identical electrical specifications and 1206 package. The primary difference is power rating: KTR18EZPF3480 is rated 0.25W (matching the main part), while ESR18EZPF3480 is rated 0.5W. KTR18EZPF3480 includes high voltage features; ESR18EZPF3480 includes pulse withstanding capability.

Q: Are the physical dimensions identical across all three parts?

A: The 1206 (3216 Metric) package designation is identical. Slight dimensional variations exist: CRCW1206348RFKEAC measures 0.120" L x 0.061" W; both Rohm parts measure 0.126" L x 0.063" W. All three have identical 0.026" (0.65mm) maximum seated height. These variations are within standard 1206 package tolerance and do not affect PCB layout compatibility.

Q: Do automotive applications require the AEC-Q200 rated substitutes?

A: Automotive applications benefit from AEC-Q200 qualification. Both ESR18EZPF3480 and KTR18EZPF3480 carry this certification. The main part CRCW1206348RFKEAC does not specify automotive rating. Selection depends on application requirements and design specifications.

Q: Is the ±100ppm/°C temperature coefficient identical across all parts?

A: Yes. All three parts specify ±100ppm/°C temperature coefficient and -55°C ~ 155°C operating temperature range, ensuring identical thermal performance characteristics.
