CRCW08053K40FKEAC Equivalent & Substitute Parts

Part Overview

The CRCW08053K40FKEAC is a 3.4 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Vishay Dale. This component is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific manufacturer certifications such as automotive AEC-Q200 qualification or enhanced moisture resistance features.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CRCW08053K40FKEAC are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Resistance value: 3.4 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Packaging format: Tape & Reel (TR)

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The three substitute parts listed below meet all core electrical, mechanical, and compliance requirements. Differences in manufacturer-specific features (such as automotive AEC-Q200 certification or moisture-resistant composition) do not disqualify substitution but may provide additional design benefits for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the CRCW08053K40FKEAC and maintain Active product status with full RoHS3 compliance. Selection among these alternatives should be based on the following factors:

CR0805-FX-3401ELF (Bourns Inc.): This substitute includes moisture-resistant composition as an additional feature. It maintains identical electrical specifications and package dimensions to the primary part, with seated height of 0.024" (0.60mm).

KTR10EZPF3401 (Rohm Semiconductor): This substitute carries AEC-Q200 automotive qualification and high voltage features. It is suitable for automotive and high-reliability applications. Seated height is 0.026" (0.65mm), which remains within typical PCB assembly tolerances.

RMCF0805FT3K40 (Stackpole Electronics Inc.): This substitute carries AEC-Q200 automotive qualification. It is suitable for automotive and high-reliability applications. Seated height is 0.026" (0.65mm), which remains within typical PCB assembly tolerances.

All parts are available in Tape & Reel packaging and maintain MSL Level 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can I use KTR10EZPF3401 or RMCF0805FT3K40 in place of CRCW08053K40FKEAC?

A: Yes. Both parts meet all core electrical parameters (3.4 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), mechanical specifications (0805 package, thick film composition), and compliance requirements (RoHS3, MSL Level 1). The seated height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances.

Q: What is the difference between CR0805-FX-3401ELF and the other substitutes?

A: CR0805-FX-3401ELF features moisture-resistant composition, whereas KTR10EZPF3401 and RMCF0805FT3K40 feature automotive AEC-Q200 qualification. All three maintain identical electrical specifications and core mechanical parameters.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the primary part specification.

Q: Does the 0.002" (0.05mm) seated height difference affect PCB assembly?

A: No. The maximum seated height variation between parts (0.024" to 0.026") falls within standard PCB assembly and reflow process tolerances for 0805 components.

Q: Are all parts RoHS3 compliant?

A: Yes. The primary part and all three substitutes are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity classification.

Q: Which substitute should I select for automotive applications?

A: KTR10EZPF3401 and RMCF0805FT3K40 both carry AEC-Q200 automotive qualification and are suitable for automotive applications. CR0805-FX-3401ELF does not carry automotive certification.
