Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08053K40FKEC is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.4 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Packaging format (Tape & Reel or Cut Tape) and seated height variations within the 0805 package specification do not affect functional interchangeability in standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the CRCW08053K40FKEC. Selection among these alternatives should be based on:

Product Status and Availability: All parts are active in production. ERJ-6ENF3401V (Panasonic) and RMCF0805FT3K40 (Stackpole) offer the highest inventory levels at 57,802 and 25,178 units respectively, supporting extended supply chain requirements.

Compliance and Certifications: CRCW08053K40FKEA, ERJ-6ENF3401V, RMCF0805FT3K40, and KTR10EZPF3401 carry AEC-Q200 automotive qualification. CR0805-FX-3401ELF from Bourns is specified with moisture-resistant composition. All parts are ROHS3 compliant with MSL 1 rating.

Manufacturer Continuity: Vishay Dale CRCW08053K40FKEA provides direct manufacturer equivalence with higher inventory (5,300 units) than the primary part. Multi-source alternatives from Panasonic, Stackpole, Rohm, and Bourns reduce single-source dependency.

Physical Dimensions: Seated height variations (0.50mm to 0.70mm) remain within 0805 package specification tolerances and do not impact standard PCB assembly or component placement.

Frequently Asked Questions (FAQ)

Q: Can CRCW08053K40FKEA be used as a direct replacement for CRCW08053K40FKEC?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (3.4 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C). The difference in part number suffix reflects packaging or manufacturing date variations that do not affect functional performance.

Q: Are all substitute parts automotive-qualified?

A: CRCW08053K40FKEA, ERJ-6ENF3401V, RMCF0805FT3K40, and KTR10EZPF3401 carry AEC-Q200 certification. CR0805-FX-3401ELF from Bourns is specified with moisture-resistant composition but does not list AEC-Q200 rating in the provided data. Verify automotive qualification requirements for your specific application.

Q: Does the difference in seated height affect PCB assembly?

A: No. All parts are 0805 (2012 Metric) package with seated heights ranging from 0.50mm to 0.70mm, all within standard 0805 package specification. Standard pick-and-place equipment and reflow processes accommodate this variation without adjustment.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both are suitable for automated assembly. Tape & Reel packaging is optimized for high-volume production runs. Cut Tape & Digi-Reel (ERJ-6ENF3401V) provides flexibility for lower-volume or mixed-component orders. Functional performance is identical.

Q: Can KTR10EZPF3401 be used in high-voltage applications?

A: KTR10EZPF3401 is specified with high-voltage thick film composition. However, all parts listed share identical resistance, tolerance, power rating, and temperature specifications. High-voltage designation indicates enhanced dielectric properties but does not change the core electrical parameters for standard 3.4 kΩ ±1% 0.125W applications.

Q: Are all parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
