Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC0402J241CS are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Primary Matching Parameters:

• Resistance value: 240 Ohms (exact match required)
• Package / Case: 01005 (0402 Metric) (exact match required)
• Power rating: 0.03W, 1/32W (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Temperature coefficient: ±250ppm/°C (exact match required)

Secondary Compatibility Parameters:

• Tolerance: ±5% or tighter (tighter tolerance is acceptable as a substitute)
• RoHS Status: ROHS3 Compliant (regulatory equivalence)
• Moisture Sensitivity Level: 1 (Unlimited) (equivalent handling requirements)
• Packaging format: Tape & Reel (TR) (standard supply format)

Substitutes must maintain all primary parameters identically. Secondary parameters may vary within acceptable engineering margins, with tighter tolerances representing improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CRCW0100240RFREL from Vishay Dale is a direct substitute for the RC0402J241CS. Both components maintain identical electrical specifications across resistance, power rating, temperature coefficient, and operating temperature range. Both are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent regulatory and handling requirements.

The primary distinction is tolerance specification: the Vishay substitute provides ±1% tolerance compared to the Samsung original's ±5% tolerance. This represents improved accuracy and is functionally compatible with applications designed for the original ±5% specification. Both components are supplied in Tape & Reel packaging format and are classified as Active products with full availability.

Selection between these parts should be based on inventory availability, lead time requirements, and cost considerations, as all electrical and mechanical parameters are equivalent or superior in the substitute part.

Frequently Asked Questions (FAQ)

Q: Can CRCW0100240RFREL replace RC0402J241CS in existing designs?

A: Yes. Both parts share identical resistance value (240 Ohms), power rating (0.03W), package (01005/0402 Metric), operating temperature range (-55°C ~ 125°C), and temperature coefficient (±250ppm/°C). The substitute's ±1% tolerance is tighter than the original's ±5%, providing improved accuracy without compromising compatibility.

Q: Are there physical dimension differences between these parts?

A: No. Both components have identical physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm) with maximum seated height of 0.006" (0.15mm). They are mechanically interchangeable on PCBs designed for the 01005 package footprint.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both RC0402J241CS and CRCW0100240RFREL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (Unlimited) moisture sensitivity level, requiring identical handling and storage protocols.

Q: What is the difference in tolerance specification?

A: The Samsung original specifies ±5% tolerance, while the Vishay substitute specifies ±1% tolerance. The ±1% tolerance is tighter and represents superior accuracy. Applications designed for ±5% tolerance will function correctly with the ±1% substitute part.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both components are supplied in Tape & Reel (TR) format, the standard packaging for automated assembly processes. This ensures compatibility with standard pick-and-place equipment and reflow soldering workflows.

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

A: Yes. Both parts maintain identical operating temperature range of -55°C ~ 125°C and identical temperature coefficient of ±250ppm/°C, ensuring equivalent performance across the full specified temperature envelope.
