Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F3834CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (3.83 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 format (1206 / 3216 Metric) and number of terminations (2) must match to ensure PCB footprint compatibility and soldering process alignment.

Regulatory & Environmental Compliance: RoHS3 compliance, REACH unaffected status, and MSL rating (1 - Unlimited) confirm suitability for equivalent applications without additional qualification.

Material Composition: Thick film construction with moisture-resistant properties maintains functional equivalence in standard operating environments.

The substitute part RC1206FR-073M83L from YAGEO meets all specified criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RC3216F3834CS and RC1206FR-073M83L are Active product status components with identical electrical and mechanical specifications. Selection between these parts is based on availability, packaging format, and supply chain requirements rather than technical performance differentiation.

The RC3216F3834CS is supplied in standard packaging format with 1111 pieces in current inventory. The RC1206FR-073M83L is supplied in Tape & Reel (TR) format with 2583 pieces in current inventory, making it suitable for automated assembly processes.

Both components satisfy ROHS3 compliance and REACH unaffected requirements, confirming regulatory equivalence for applications subject to environmental directives. MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073M83L replace RC3216F3834CS in existing designs?

A: Yes. Both components share identical electrical specifications (3.83 MOhms ±1%, 0.25W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical form factor (1206 / 3216 Metric package). Direct substitution is supported without circuit redesign.

Q: What is the difference in physical dimensions between these parts?

A: RC3216F3834CS dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated height of 0.026" (0.66mm). RC1206FR-073M83L dimensions are 0.122" L x 0.063" W (3.10mm x 1.60mm) with maximum seated height of 0.026" (0.65mm). Both fit the 1206 package footprint with negligible dimensional variance.

Q: Are there packaging format considerations for component selection?

A: RC3216F3834CS is supplied in standard packaging. RC1206FR-073M83L is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly. Selection depends on production methodology and inventory management requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Regulatory and environmental compliance is equivalent across both parts.

Q: What determines substitution eligibility for 1206 chip resistors?

A: Substitution requires matching resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package format, and compliance certifications. Dimensional variance within package specification limits does not affect substitution eligibility.
