Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS3216F3834CS is based on the following critical parameters that must remain constant across equivalent components:

Electrical Parameters:

• Resistance value: 3.83 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package format: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Compliance & Environmental:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status

The RC1206FR-073M83L from YAGEO meets all electrical and mechanical substitution criteria. While the RCS3216F3834CS includes anti-sulfur protection as an additional feature, both components satisfy the core functional requirements for high-impedance applications in the specified temperature and humidity environments.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS3216F3834CS and RC1206FR-073M83L are active production components with full RoHS3 compliance and REACH unaffected status, making them suitable for applications subject to environmental and regulatory requirements. The components are electrically and mechanically equivalent within standard PCB assembly tolerances.

The RCS3216F3834CS includes anti-sulfur protection as a distinguishing feature. Selection between these components should be based on application environment requirements and supply chain availability. Both components maintain identical electrical performance across the specified operating temperature range and are compatible with standard 1206 footprint designs.

The dimensional variance in length (3.20mm versus 3.10mm) falls within acceptable tolerances for 1206 package specifications and does not affect PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-073M83L be used as a direct replacement for RCS3216F3834CS?

A: Yes. Both components share identical electrical specifications (3.83 MOhms ±1%, 0.25W, ±100ppm/°C), operate across the same temperature range (-55°C to 155°C), and are packaged in the 1206 (3216 Metric) format. Physical dimensions are within standard package tolerances for PCB assembly compatibility.

Q: What is the difference between these two resistors?

A: The primary difference is the anti-sulfur feature included in the RCS3216F3834CS. The RC1206FR-073M83L provides moisture resistance without the anti-sulfur protection. Both components meet MSL 1 requirements and are suitable for standard industrial environments.

Q: Are there packaging differences between these parts?

A: The RCS3216F3834CS is supplied in standard packaging, while the RC1206FR-073M83L is available in Tape & Reel (TR) format. Both are compatible with automated assembly processes. The physical dimensions are within 1206 package specifications.

Q: Do both parts meet compliance requirements?

A: Yes. Both the RCS3216F3834CS and RC1206FR-073M83L are ROHS3 compliant, REACH unaffected, and carry MSL 1 ratings, meeting standard environmental and regulatory requirements for commercial and industrial applications.

Q: What determines substitution eligibility for these resistors?

A: Substitution is determined by matching resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package format, and compliance certifications. Both components satisfy all these criteria.
