Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC0402J202CS are identified based on the following critical parameters that determine functional interchangeability:

Mandatory Matching Parameters:

• Resistance value: 2 kOhms
• Package / Case: 01005 (0402 Metric)
• Power rating: 0.03W (1/32W)
• Composition: Thick Film
• Temperature coefficient: ±250ppm/°C
• Operating temperature range: -55°C ~ 125°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: MSL 1

Allowable Variation:

• Tolerance: The main part specifies ±5%. Substitute parts with tighter tolerance (±1%) are acceptable as they meet or exceed the original specification requirement.

The CRCW01002K00FREL from Vishay Dale meets all mandatory parameters and provides improved tolerance specification, making it a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The CRCW01002K00FREL is a direct substitute for the RC0402J202CS. Both components are Active product status with identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification). The substitute part provides equivalent or superior performance across all specified parameters. The tighter tolerance specification (±1% versus ±5%) of the substitute part represents an improvement in precision without introducing any compatibility issues. Both components share identical package dimensions, thermal characteristics, and environmental ratings. Selection between these parts may be based on availability, lead time, or cost considerations, as all technical and compliance requirements are satisfied by either option.

Frequently Asked Questions (FAQ)

Q: Can CRCW01002K00FREL replace RC0402J202CS in existing designs?

A: Yes. The CRCW01002K00FREL is a direct substitute. Both parts share identical resistance value, power rating, package dimensions (01005 / 0402 Metric), operating temperature range, and compliance certifications. The substitute part's tighter tolerance (±1%) is compatible with applications designed for ±5% tolerance.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the RC0402J202CS and CRCW01002K00FREL use the 01005 (0402 Metric) package with dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum seated height of 0.006" (0.15mm). They are mechanically interchangeable.

Q: What is the significance of the tolerance difference?

A: The RC0402J202CS specifies ±5% tolerance, while the CRCW01002K00FREL specifies ±1% tolerance. The substitute part provides tighter tolerance, meaning its actual resistance value will be closer to the nominal 2 kOhm specification. This is an improvement and does not create compatibility issues.

Q: Do both parts have the same environmental ratings?

A: Yes. Both components operate across -55°C to 125°C, have MSL 1 (Unlimited) moisture sensitivity level, and are ROHS3 compliant. Environmental performance is identical.

Q: Are there any packaging differences?

A: Both parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. No packaging conversion is required.

Q: What compliance certifications apply to both parts?

A: Both the RC0402J202CS and CRCW01002K00FREL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. They meet identical regulatory requirements.
