Parameter Comparison

Engineering Selection Recommendations

All three parts—CRCW0805510RFKEBC (Vishay Dale), CR0805-FX-5100ELF (Bourns Inc.), and KTR10EZPF5100 (Rohm Semiconductor)—are Active product status and ROHS3 compliant. Selection among these equivalents is based on availability, supply chain considerations, and application-specific certifications.

CR0805-FX-5100ELF includes moisture-resistant features within the standard thick film composition. KTR10EZPF5100 carries AEC-Q200 automotive qualification and high voltage designation, making it suitable for automotive and high-reliability applications. The CRCW0805510RFKEBC remains the primary reference part. Height variation between CRCW0805510RFKEBC / CR0805-FX-5100ELF (0.024" maximum) and KTR10EZPF5100 (0.026" maximum) is within standard PCB assembly tolerances and does not affect functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can CR0805-FX-5100ELF replace CRCW0805510RFKEBC directly?

A: Yes. Both parts share identical electrical specifications (510 Ohms ±1%, 0.125W), package dimensions (0805), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The CR0805-FX-5100ELF includes moisture-resistant features as an additional characteristic. Physical dimensions are equivalent.

Q: Is KTR10EZPF5100 suitable for non-automotive applications?

A: Yes. KTR10EZPF5100 meets all core electrical and mechanical requirements of CRCW0805510RFKEBC. AEC-Q200 automotive qualification and high voltage designation represent additional certifications that do not restrict use in general industrial or consumer applications. The part is fully compatible with standard 0805 PCB layouts.

Q: What is the significance of the height difference between KTR10EZPF5100 and the other parts?

A: KTR10EZPF5100 has a maximum seated height of 0.026" (0.65mm) compared to 0.024" (0.60mm) for CRCW0805510RFKEBC and CR0805-FX-5100ELF. This 0.002" (0.05mm) difference is within standard PCB assembly and component placement tolerances and does not affect functional interchangeability or board-level compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. CRCW0805510RFKEBC, CR0805-FX-5100ELF, and KTR10EZPF5100 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging format is used for these parts?

A: All three parts are supplied in Tape & Reel (TR) format, standard for high-volume SMD component distribution and automated assembly processes.
