Substitute Part Grouping Explanation

Substitute parts for the CRCW040256R0FKTD are qualified based on the following criteria:

• Identical resistance value: 56 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.063W (1/16W)
• Same package format: 0402 (1005 Metric)
• Identical physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm), height 0.016" (0.40mm) maximum
• Matching composition: Thick Film
• Equivalent temperature coefficient: ±100ppm/°C
• Same operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity: MSL 1 (Unlimited)

Substitutes differ only in packaging format (Tape & Reel versus Cut Tape) and manufacturer identity, with no impact on electrical or mechanical performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain identical electrical and mechanical specifications. Selection between CRCW040256R0FKTD and its substitutes depends on regulatory compliance requirements and packaging logistics:

CRCW040256R0FKTD (Vishay Dale, Tape & Reel) is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status is permissible.

CRCW040256R0FKED (Vishay Dale, Cut Tape & Digi-Reel) provides ROHS3 compliance and REACH-unaffected status while maintaining Vishay Dale manufacturer continuity. Cut Tape packaging accommodates lower-volume or mixed-component assembly requirements.

RMCF0402FT56R0 (Stackpole Electronics, Tape & Reel) provides ROHS3 compliance and REACH-unaffected status with alternative manufacturer sourcing. Tape & Reel packaging supports high-volume automated assembly.

Frequently Asked Questions (FAQ)

Q: Can CRCW040256R0FKED replace CRCW040256R0FKTD in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications (56 Ohms ±1%, 0.063W, ±100ppm/°C, -55°C to 155°C). The difference is packaging format (Cut Tape versus Tape & Reel) and regulatory compliance status. Electrical and thermal performance in circuit are equivalent.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape supplies individual tape segments, suitable for lower-volume production or mixed-component kits. Both formats contain identical components.

Q: Can RMCF0402FT56R0 be used as a direct substitute for CRCW040256R0FKTD?

A: Yes. RMCF0402FT56R0 meets all electrical and mechanical requirements: 56 Ohms ±1%, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. The manufacturer differs (Stackpole Electronics versus Vishay Dale), but performance characteristics are equivalent.

Q: Are there compliance differences between these parts?

A: Yes. CRCW040256R0FKTD is RoHS non-compliant and REACH-affected. CRCW040256R0FKED and RMCF0402FT56R0 are both ROHS3 compliant and REACH-unaffected. Select based on your application's regulatory requirements.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What determines substitutability for this 0402 resistor?

A: Substitutability is determined by matching resistance value (56 Ohms), tolerance (±1%), power rating (0.063W), package dimensions (0402 / 1.00mm x 0.50mm), composition (Thick Film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and automotive qualification (AEC-Q200). Packaging format and manufacturer are secondary considerations that do not affect circuit performance.
