Substitute Part Grouping Explanation

Substitution eligibility for the RC0402F123CS is determined by strict equivalence across the following critical parameters:

• Resistance Value: 12 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.03W / 1/32W (exact match required)
• Package Format: 01005 (0402 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±250ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The CRCW010012K0FREL manufactured by Vishay Dale meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0402F123CS and CRCW010012K0FREL are active production components with identical electrical specifications, mechanical dimensions, and regulatory compliance profiles. Selection between these parts is based on procurement availability, supply chain logistics, and inventory status rather than technical performance differences.

The RC0402F123CS (Samsung Electro-Mechanics) carries 1,038 pieces in current inventory. The CRCW010012K0FREL (Vishay Dale) carries 31,234 pieces in current inventory. Both components satisfy ROHS3 compliance requirements and REACH unaffected status, making either suitable for applications requiring regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can CRCW010012K0FREL be used as a direct replacement for RC0402F123CS in PCB assembly?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. They share the same 01005 (0402 Metric) package format, identical physical dimensions (0.40mm x 0.20mm), and matching termination specifications. No circuit redesign or PCB layout modification is required.

Q: Are there differences in moisture sensitivity or storage requirements between these parts?

A: No. Both components carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and storage requirements. No special handling or baking procedures are required prior to assembly.

Q: Do these parts have different temperature coefficients?

A: No. Both the RC0402F123CS and CRCW010012K0FREL specify ±250ppm/°C temperature coefficient and operate across the identical temperature range of -55°C to 125°C.

Q: What is the significance of the 01005 package designation?

A: The 01005 package is the metric equivalent of the 0402 imperial designation. This ultra-miniature package measures 0.40mm x 0.20mm and is used in high-density PCB applications. Both substitute parts use this identical package format.

Q: Are there any regulatory or compliance differences between these manufacturers?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030. No compliance-related restrictions apply to either part.

Q: Can these parts be mixed within the same production batch?

A: Yes. Since both parts are electrically and mechanically equivalent with identical compliance certifications, they can be used interchangeably within the same assembly without functional or reliability impact.
