Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3404CS is determined by the following critical parameters:

Electrical Specifications: Resistance value (3.4 MOhms), tolerance (±1%), and power rating (0.25W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package type (1206 / 3216 Metric), physical dimensions (0.126" L x 0.063" W), and number of terminations (2) ensure physical fit and solderability.

Compliance & Environmental: RoHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status confirm regulatory alignment and handling requirements.

The CRCW12063M40FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F3404CS and CRCW12063M40FKEA are Active status components with identical electrical and mechanical specifications. Selection between these parts is based on availability, supply chain requirements, and application-specific certifications.

The CRCW12063M40FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring this certification. The RCS3216F3404CS features anti-sulfur and moisture-resistant construction, providing enhanced environmental protection in corrosive or high-humidity environments.

Both components are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. Seated height difference (0.026" vs 0.024") is negligible for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW12063M40FKEA directly replace RCS3216F3404CS in existing designs?

A: Yes. Both components share identical resistance (3.4 MOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Physical dimensions and termination count are equivalent.

Q: What is the difference in seated height between these parts?

A: RCS3216F3404CS has maximum seated height of 0.026" (0.66mm), while CRCW12063M40FKEA is 0.024" (0.60mm). This 0.002" difference does not affect standard PCB assembly or component placement.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, meeting identical thermal specifications.

Q: What packaging formats are available?

A: RCS3216F3404CS is supplied in standard packaging. CRCW12063M40FKEA is available in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Do both parts meet automotive standards?

A: CRCW12063M40FKEA carries AEC-Q200 automotive qualification. RCS3216F3404CS does not list automotive certification but meets general industrial compliance requirements.

Q: Are moisture sensitivity considerations different between these parts?

A: No. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture precautions are required during storage or handling.
