CRCW040239K2FKTD Equivalent & Substitute Parts

Part Overview

The CRCW040239K2FKTD is a 39.2 kOhms ±1% thick film chip resistor in 0402 (1005 Metric) package rated for 1/16W (0.063W) power dissipation. Manufactured by Vishay Dale, this component meets AEC-Q200 automotive qualification standards and operates across -55°C to 155°C. The part is currently active in production. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and automotive ratings are maintained across alternative manufacturers or packaging variants.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CRCW040239K2FKTD are qualified based on the following criteria:

• Identical resistance value: 39.2 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 0.063W (1/16W)
• Same package: 0402 (1005 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Same operating temperature range: -55°C ~ 155°C
• AEC-Q200 automotive qualification maintained
• Identical physical dimensions and termination count

Two substitute parts meet these criteria: CRCW040239K2FKED (Vishay Dale, alternative packaging variant) and RMCF0402FT39K2 (Stackpole Electronics Inc, alternative manufacturer).

Parameter Comparison

Engineering Selection Recommendations

CRCW040239K2FKED serves as a direct substitute within the Vishay Dale product line, offering ROHS3 compliance and REACH unaffected status, compared to the original part's RoHS non-compliant designation. This variant maintains identical electrical and mechanical specifications while providing improved environmental compliance for applications subject to regulatory requirements.

RMCF0402FT39K2 from Stackpole Electronics Inc provides cross-manufacturer substitution with equivalent performance characteristics. This part also carries ROHS3 compliance and REACH unaffected status. Selection between Vishay Dale and Stackpole variants depends on supply chain requirements, inventory availability, and established qualification protocols for the target application.

All three parts maintain active product status and are suitable for automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can CRCW040239K2FKED replace CRCW040239K2FKTD in existing designs?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (39.2 kOhms ±1%, 0.063W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and physical dimensions (0402 package). The primary difference is packaging variant designation and improved RoHS/REACH compliance status of the FKED variant.

Q: Is RMCF0402FT39K2 compatible with applications designed for CRCW040239K2FKTD?

A: Yes. RMCF0402FT39K2 maintains all critical electrical parameters, mechanical dimensions, and AEC-Q200 automotive qualification. Cross-manufacturer substitution is valid when supply constraints or procurement requirements necessitate Stackpole Electronics components.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: resistance value (39.2 kOhms), tolerance (±1%), power rating (0.063W), package type (0402), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 qualification. Deviation in any parameter disqualifies a part as a direct substitute.

Q: Are there compliance differences between the three parts?

A: CRCW040239K2FKTD is RoHS non-compliant and REACH affected. CRCW040239K2FKED and RMCF0402FT39K2 are both ROHS3 compliant and REACH unaffected. Applications requiring regulatory compliance should specify the FKED or RMCF variant.

Q: Does package designation (FKTD vs FKED) affect circuit performance?

A: No. Package designation indicates tape and reel configuration and compliance variant only. Electrical performance and physical footprint remain identical.
