Parameter Comparison

Engineering Selection Recommendations

CRCW0805931RFKEAC (Primary): Active product status with current inventory availability. Recommended for new designs and ongoing production requirements.

CR0805-FX-9310ELF (Bourns Inc.): Active product with moisture-resistant composition feature. Suitable as a direct substitute with equivalent electrical and mechanical specifications. Height specification matches the primary part at 0.024" (0.60mm).

MCR10ERTF9310 (Rohm Semiconductor): Meets all electrical and mechanical requirements with equivalent specifications. Product status is discontinued at DiGi Electronics; verify availability through alternative distribution channels before selection. Height specification is 0.026" (0.65mm), which remains within acceptable PCB assembly tolerances for 0805 packages.

All three parts are ROHS3 compliant, REACH unaffected, and carry identical compliance certifications (ECCN: EAR99, HTSUS: 8533.21.0030).

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF9310 be used as a direct replacement for CRCW0805931RFKEAC?

A: Yes. Both parts share identical electrical parameters (931 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), mechanical package (0805), and compliance certifications. The height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances for this package class.

Q: What is the difference between CR0805-FX-9310ELF and the primary part?

A: CR0805-FX-9310ELF includes moisture-resistant composition as an additional feature. All electrical specifications, tolerance, power rating, temperature range, and package dimensions are identical. Height specification matches at 0.024" (0.60mm).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CRCW0805931RFKEAC, MCR10ERTF9310, and CR0805-FX-9310ELF are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the PCB design accommodates the maximum height specification of 0.026" (0.65mm) for MCR10ERTF9310. Both CRCW0805931RFKEAC and CR0805-FX-9310ELF have identical height at 0.024" (0.60mm).

Q: What should be considered when selecting between these parts?

A: Selection should be based on product availability, supply chain status, and application-specific requirements. CRCW0805931RFKEAC and CR0805-FX-9310ELF are both active products. MCR10ERTF9310 is discontinued at DiGi Electronics and requires verification of alternative supplier availability.
