Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08053K92FKEC is determined by strict equivalence across the following parameters: resistance value (3.92 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 identified substitute parts meet these electrical and mechanical specifications. Compliance certifications (RoHS3, REACH Unaffected, AEC-Q200 where applicable) and moisture sensitivity level (MSL 1) are maintained across substitutes. Physical dimensions remain within specification across all alternatives, with seated height variations noted but within acceptable tolerances for 0805 package class.

Parameter Comparison

Engineering Selection Recommendations

For active production designs, CRCW08053K92FKEA (Vishay Dale) is the primary equivalent with highest inventory availability (36,241 units) and identical specifications to the main part. RMCF0805FT3K92 (Stackpole Electronics Inc) offers the largest inventory reserve (131,297 units) with full AEC-Q200 automotive qualification and active product status. ERJ-6ENF3921V (Panasonic Electronic Components) provides an alternative from a major manufacturer with 63,073 units in stock and AEC-Q200 certification.

For designs requiring automotive AEC-Q200 compliance, select from: CRCW08053K92FKEA, CRCW08053K92FKEB, ERJ-6ENF3921V, RMCF0805FT3K92, or KTR10EZPF3921. The KTR10EZPF3921 variant includes high voltage thick film construction as an upgrade option where enhanced voltage performance is required.

CRCW08053K92FKEAC and CR0805-FX-3921ELF are manufacturer-recommended alternatives without AEC-Q200 rating; CR0805-FX-3921ELF includes moisture-resistant construction. Avoid CRCW08053K92FKEB and MCR10ERTF3921 for new designs due to discontinued status, though existing inventory remains available.

All substitutes maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. Physical height variations (0.50mm to 0.70mm seated maximum) fall within standard 0805 package tolerances and do not affect PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW08053K92FKEA be used as a direct replacement for CRCW08053K92FKEC?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (3.92 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), package type (0805), composition (thick film), and automotive AEC-Q200 rating. Seated height is identical at 0.50mm maximum.

Q: What is the difference between CRCW08053K92FKEC and CRCW08053K92FKEAC?

A: CRCW08053K92FKEAC is from the CRCW-C series and lacks AEC-Q200 automotive certification. Seated height is 0.60mm versus 0.50mm for the main part. Electrical parameters remain equivalent. Use CRCW08053K92FKEAC only in non-automotive applications.

Q: Are all substitute parts suitable for automotive applications?

A: No. Only parts with AEC-Q200 rating are qualified for automotive use: CRCW08053K92FKEA, CRCW08053K92FKEB, ERJ-6ENF3921V, RMCF0805FT3K92, and KTR10EZPF3921. CRCW08053K92FKEAC, CR0805-FX-3921ELF, and MCR10ERTF3921 lack this certification.

Q: Does seated height variation affect PCB assembly?

A: No. All substitute parts maintain seated heights within 0.50mm to 0.70mm maximum, which falls within standard 0805 (2012 Metric) package class tolerances. PCB pad design and reflow profiles remain unchanged.

Q: Which substitute offers the best inventory availability?

A: RMCF0805FT3K92 (Stackpole Electronics Inc) has the highest inventory at 131,297 units with full AEC-Q200 automotive qualification and active product status.

Q: Can KTR10EZPF3921 be used as an upgrade?

A: Yes. KTR10EZPF3921 includes high voltage thick film construction while maintaining all core electrical specifications. It is suitable for applications requiring enhanced voltage performance within the same 0805 package footprint.

Q: Should I avoid discontinued parts?

A: CRCW08053K92FKEB and MCR10ERTF3921 are discontinued at DiGi Electronics but retain existing inventory. Use only if supply chain continuity is not a concern. For new designs, select from active status parts.
