Parameter Comparison

Engineering Selection Recommendations

All three parts listed—CRCW0805511RFKEBC, CRCW0805511RFKEAC, and CR0805-FX-5110ELF—are Active product status components with full RoHS3 compliance and REACH Unaffected status. They meet identical electrical and mechanical specifications for 511 Ohm ±1% 0.125W 0805 thick film chip resistors.

CRCW0805511RFKEAC is a direct equivalent from Vishay Dale with identical specifications and packaging. CR0805-FX-5110ELF is manufactured by Bourns Inc. and includes moisture-resistant thick film composition as an additional feature while maintaining all core electrical and mechanical parameters.

Selection between these parts should be based on availability, lead time, and procurement requirements, as all three are functionally equivalent for applications requiring 511 Ohm ±1% 0.125W 0805 resistors.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805511RFKEAC be used as a direct replacement for CRCW0805511RFKEBC?

A: Yes. Both parts are manufactured by Vishay Dale and share identical electrical specifications (511 Ohms ±1%, 0.125W), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and mechanical package (0805 / 2012 Metric). Both are RoHS3 compliant with MSL 1 (Unlimited) and REACH Unaffected status.

Q: Is CR0805-FX-5110ELF compatible with CRCW0805511RFKEBC?

A: Yes. CR0805-FX-5110ELF from Bourns Inc. meets all electrical and mechanical requirements: 511 Ohms ±1%, 0.125W, thick film composition, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and 0805 (2012 Metric) package. The additional moisture-resistant feature does not affect compatibility. Both are RoHS3 compliant with MSL 1 (Unlimited) and REACH Unaffected status.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: resistance value (511 Ohms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Compliance certifications (RoHS3, REACH Unaffected, MSL 1) must also align.

Q: Are there packaging differences between these parts?

A: All three parts are supplied in Tape & Reel (TR) packaging format. Physical dimensions and height specifications are identical across all three parts.

Q: What is the difference between CRCW0805511RFKEBC and CRCW0805511RFKEAC?

A: Both are Vishay Dale CRCW-C series 511 Ohm ±1% 0.125W 0805 resistors with identical electrical and mechanical specifications. The difference lies in packaging or manufacturing batch designation indicated by the suffix (RFKEBC vs. RFKEAC), but both are functionally equivalent for circuit applications.

Q: Does CR0805-FX-5110ELF have any performance advantages?

A: CR0805-FX-5110ELF includes moisture-resistant thick film composition as a specified feature. All other electrical parameters, temperature performance, and compliance certifications are equivalent to the Vishay Dale parts. Selection should be based on application requirements and supply availability.
