Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3654CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (3.65 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) and number of terminations (2) ensure physical fit and solderability in existing PCB layouts.

Environmental & Compliance Requirements: RoHS3 compliance, Moisture Sensitivity Level 1, and REACH Unaffected status confirm regulatory alignment and handling compatibility.

The substitute part RC1206FR-073M65L from YAGEO meets all these criteria, with minor dimensional variations within acceptable tolerances for the 1206 package standard.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F3654CS and RC1206FR-073M65L are Active status components with full RoHS3 compliance and REACH Unaffected designation, confirming regulatory suitability for current and future applications. The dimensional differences (length 3.20mm vs. 3.10mm, height 0.66mm vs. 0.65mm) fall within standard 1206 package tolerances and do not affect PCB layout compatibility or soldering processes. Both parts carry Moisture Sensitivity Level 1, indicating unlimited shelf life without special storage requirements. Selection between these parts may be based on availability, packaging format (Samsung offers standard packaging; YAGEO offers Tape & Reel), or supply chain preferences, as electrical and thermal performance are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073M65L be used as a direct replacement for RCS3216F3654CS?

A: Yes. Both parts share identical electrical specifications (3.65 MOhms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and package type (1206 / 3216 Metric). Dimensional variations are within 1206 package tolerances and do not affect circuit performance or PCB assembly.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Samsung vs. YAGEO), packaging format (standard vs. Tape & Reel), and minor dimensional tolerances. The RCS3216F3654CS includes anti-sulfur protection, while the RC1206FR-073M65L specifies moisture resistance. Both provide equivalent environmental protection at Moisture Sensitivity Level 1.

Q: Are there any compliance or certification concerns when substituting?

A: No. Both parts are RoHS3 compliant, REACH Unaffected, and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.21.0030), ensuring seamless substitution from a compliance perspective.

Q: Does the packaging format affect substitution eligibility?

A: Packaging format (standard vs. Tape & Reel) affects supply chain logistics and handling but does not impact electrical or mechanical compatibility. Component selection should consider manufacturing process requirements and inventory management practices.

Q: What tolerance range should be expected from these resistors?

A: Both parts are rated at ±1% tolerance, meaning the actual resistance value will fall within 3.6135 MOhms to 3.6865 MOhms at 25°C. This tolerance applies consistently across the operating temperature range with the specified ±100ppm/°C temperature coefficient.
