Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW0805931RFKEBC is determined by strict equivalence across the following parameters: resistance value (931 Ohms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH Unaffected). All identified substitute parts meet these criteria without exception.

The substitute parts are categorized as follows:

Direct Equivalent: MCR10ERTF9310 (Rohm Semiconductor) — functionally identical across all electrical and mechanical parameters. Product status is discontinued at DiGi Electronics.

Upgrade Equivalent: CR0805-FX-9310ELF (Bourns Inc.) — meets all electrical specifications with the addition of moisture-resistant thick film composition. Product status is active.

Parameter Comparison

Engineering Selection Recommendations

CRCW0805931RFKEBC (Primary Selection): Active product status with 1,039 units in stock. Recommended for new designs and ongoing production where supply continuity is prioritized.

CR0805-FX-9310ELF (Preferred Substitute): Active product status with moisture-resistant thick film composition. Recommended when the primary part is unavailable. The moisture-resistant feature provides enhanced environmental protection without altering electrical performance or package compatibility.

MCR10ERTF9310 (Secondary Substitute): Discontinued at DiGi Electronics with 9,100 units in stock. Suitable for applications where existing inventory must be utilized, provided supply chain verification confirms availability through alternative distribution channels. Height specification (0.026" seated maximum) is marginally higher than the primary part (0.024") but remains within standard PCB assembly tolerances for 0805 packages.

Frequently Asked Questions (FAQ)

Q: Can MCR10ERTF9310 be used as a direct replacement for CRCW0805931RFKEBC?

A: Yes. All electrical parameters (931 Ohms, ±1% tolerance, 0.125W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical specifications (0805 package, 2.00mm x 1.25mm dimensions) are identical. The seated height difference (0.026" vs. 0.024") is within standard PCB assembly tolerances and does not affect functionality or compatibility.

Q: What is the advantage of CR0805-FX-9310ELF over the primary part?

A: CR0805-FX-9310ELF incorporates moisture-resistant thick film composition, providing enhanced environmental protection in humid or corrosive conditions. All electrical specifications remain identical, and the part is currently active in production.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CRCW0805931RFKEBC, MCR10ERTF9310, and CR0805-FX-9310ELF are all ROHS3 compliant and REACH unaffected.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts share identical 0805 (2012 Metric) package specifications and footprints. No PCB layout modifications are required for substitution.

Q: What is the moisture sensitivity level for all parts?

A: All parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
