Engineering Selection Recommendations

RC0402F151CS (Samsung Electro-Mechanics)

Primary selection for applications requiring Samsung-specific supply chain qualification or existing design validation with Samsung components. Active product status with established inventory (1057 Pcs) supports immediate procurement. Full RoHS3 compliance and REACH unaffected status meet regulatory requirements for consumer and industrial applications.

CRCW0100150RFREL (Vishay Dale)

Direct functional equivalent with identical electrical and mechanical specifications. Suitable for applications where Vishay Dale supply chain integration is preferred or when Samsung component availability is constrained. Significantly higher inventory availability (50474 Pcs) supports high-volume production requirements. Active product status with equivalent RoHS3 and REACH compliance ensures regulatory alignment.

Both parts are suitable for direct substitution in circuit designs without modification to PCB layout, schematic, or thermal management strategies.

Frequently Asked Questions (FAQ)

Q: Can CRCW0100150RFREL replace RC0402F151CS in existing designs?

A: Yes. Both components share identical resistance value (150 Ohms), tolerance (±1%), power rating (0.03W), package format (01005), physical dimensions, temperature coefficient (±250ppm/°C), and operating temperature range (-55°C ~ 125°C). No circuit redesign or board layout modification is required.

Q: Are there differences in moisture resistance between these parts?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating equivalent moisture resistance performance. The RC0402F151CS is explicitly specified as moisture resistant; the CRCW0100150RFREL carries the same MSL rating, confirming equivalent moisture handling capability.

Q: What is the significance of the 01005 (0402 Metric) package designation?

A: The 01005 package is the smallest standard chip resistor format (0.40mm x 0.20mm). Both parts use this identical package, ensuring mechanical compatibility with PCB footprints, pick-and-place equipment, and reflow soldering processes without modification.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both RC0402F151CS and CRCW0100150RFREL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. They satisfy equivalent regulatory requirements for consumer, industrial, and commercial applications.

Q: Which part should be selected for high-volume production?

A: CRCW0100150RFREL (Vishay Dale) offers significantly higher inventory availability (50474 Pcs versus 1057 Pcs), supporting high-volume production schedules without supply chain delays. Both parts are functionally equivalent for this application.

Q: Are there performance differences in temperature coefficient or operating range?

A: No. Both parts specify identical temperature coefficient (±250ppm/°C) and operating temperature range (-55°C ~ 125°C), ensuring equivalent performance across thermal operating conditions.
