Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08058K45FKTC is determined by strict equivalence across the following parameters: resistance value (8.45 kOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical specifications. Physical dimensions (length, width, height) and termination count remain consistent across all alternatives. Moisture sensitivity level (MSL 1) is maintained across all substitutes. Packaging format (Tape & Reel or Cut Tape) does not affect electrical or mechanical compatibility. RoHS compliance status and REACH classification may vary between manufacturers but do not impact functional substitution.

Engineering Selection Recommendations

For automotive AEC-Q200 applications requiring full compliance certification, select from CRCW08058K45FKEA, ERJ-6ENF8451V, RMCF0805FT8K45, or KTR10EZPF8451. These parts maintain AEC-Q200 rating and ROHS3 compliance status.

For applications where AEC-Q200 certification is not mandatory, CR0805-FX-8451ELF (Bourns) and MCR10ERTF8451 (Rohm) provide functional equivalence with ROHS3 compliance. MCR10ERTF8451 is discontinued at DiGi Electronics and should be considered only if alternative sourcing is available.

CRCW08058K45FKEAC (Vishay Dale) is manufacturer-recommended and offers the highest inventory availability (40,812 pcs) but does not carry AEC-Q200 rating. This part is suitable for non-automotive applications or designs where automotive certification is not required.

Physical height variations exist across substitutes (0.50mm to 0.70mm maximum seated height). Verify PCB layout clearance requirements before final selection, particularly in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can CRCW08058K45FKTC be replaced with CRCW08058K45FKEAC? A: Yes, electrically and mechanically. Both are Vishay Dale 8.45 kOhms ±1% 0.125W 0805 resistors with identical electrical specifications. CRCW08058K45FKEAC is ROHS3 compliant and has higher inventory availability. However, CRCW08058K45FKTC carries AEC-Q200 automotive certification while CRCW08058K45FKEAC does not. Use CRCW08058K45FKEAC only in non-automotive applications or where automotive qualification is not required.

Q: Are all substitute parts suitable for automotive applications? A: No. Only CRCW08058K45FKEA, ERJ-6ENF8451V, RMCF0805FT8K45, and KTR10EZPF8451 maintain AEC-Q200 automotive qualification. CR0805-FX-8451ELF and MCR10ERTF8451 do not carry AEC-Q200 rating and are suitable only for non-automotive designs.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect compatibility? A: No. Packaging format affects only handling and assembly logistics, not electrical or mechanical compatibility. MCR10ERTF8451 is supplied in Cut Tape & Digi-Reel format while others use Tape & Reel, but all are functionally equivalent in the circuit.

Q: What is the significance of the height variation across substitutes? A: Maximum seated heights range from 0.50mm to 0.70mm. In designs with tight vertical clearance constraints (such as stacked components or low-profile assemblies), verify that the selected substitute fits within available space. ERJ-6ENF8451V has the highest maximum height at 0.70mm.

Q: Is MCR10ERTF8451 still available for new designs? A: MCR10ERTF8451 is discontinued at DiGi Electronics. While 897 pcs remain in inventory, this part should not be selected for new designs requiring long-term supply assurance. Use CRCW08058K45FKEA, ERJ-6ENF8451V, RMCF0805FT8K45, or KTR10EZPF8451 for ongoing production.

Q: What does MSL 1 (Unlimited) mean for these resistors? A: MSL 1 indicates the lowest moisture sensitivity level. These resistors can be stored indefinitely without moisture baking requirements and are suitable for standard warehouse conditions without special handling.

Q: Can I use CR0805-FX-8451ELF in place of CRCW08058K45FKTC in an automotive design? A: No. CR0805-FX-8451ELF does not carry AEC-Q200 automotive certification. It is suitable only for non-automotive applications. For automotive designs, use CRCW08058K45FKEA, ERJ-6ENF8451V, RMCF0805FT8K45, or KTR10EZPF8451.
