Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0402F512CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 5.1 kOhms
• Tolerance: ±1%
• Power rating: 0.03W (1/32W)
• Temperature coefficient: ±250ppm/°C
• Operating temperature range: -55°C ~ 125°C

Mechanical Specifications:

• Package type: 01005 (0402 Metric)
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Maximum seated height: 0.006" (0.15mm)
• Number of terminations: 2

Compliance & Environmental:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all electrical and mechanical parameters without deviation. Composition type (Thick Film) and product status (Active) are additional alignment criteria.

Parameter Comparison

Engineering Selection Recommendations

The CRCW01005K10FREL (Vishay Dale) is a direct equivalent substitute for the RC0402F512CS (Samsung Electro-Mechanics). Both components satisfy identical electrical and mechanical specifications, including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Both are packaged in 01005 (0402 Metric) format with matching physical dimensions and termination configuration.

Compliance alignment is complete: both components are ROHS3 Compliant, REACH Unaffected, and classified with Moisture Sensitivity Level 1 (Unlimited). Both maintain Active product status, ensuring long-term availability and supply chain stability.

Selection between these two parts may be determined by inventory availability, supplier lead times, or established procurement preferences, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can the CRCW01005K10FREL replace the RC0402F512CS in existing designs?

A: Yes. The CRCW01005K10FREL is a direct substitute. All electrical parameters (5.1 kOhms ±1%, 0.03W, ±250ppm/°C, -55°C ~ 125°C) and mechanical specifications (01005 package, 0.40mm x 0.20mm dimensions) are identical. No circuit redesign or board layout modification is required.

Q: Are there any compliance or environmental differences between these parts?

A: No. Both components are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Regulatory and environmental certifications are equivalent.

Q: What determines substitution eligibility for 01005 chip resistors?

A: Substitution requires exact matching of resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package type, and physical dimensions. Composition type (Thick Film) and compliance certifications must also align. Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Is the moisture-resistant feature of the RC0402F512CS present in the CRCW01005K10FREL?

A: Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating unlimited shelf life without moisture sensitivity constraints. The RC0402F512CS explicitly lists "Moisture Resistant" as a feature; the CRCW01005K10FREL achieves equivalent moisture performance through its MSL classification.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. Both components are Active products from established manufacturers with identical electrical specifications, temperature performance, and compliance certifications. Interchangeability is supported for applications requiring precision resistors in ultra-compact form factors.
