RCS3216F7870CS Equivalent & Substitute Parts

Part Overview

The RCS3216F7870CS is a 787 Ohm ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component is classified as Active product status with anti-sulfur and moisture-resistant properties. The part is ROHS3 compliant and suitable for general industrial and consumer applications requiring precision resistive elements in compact surface-mount form factors.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified suppliers is needed while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F7870CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 787 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Allowable Variations:

• Physical dimensions may vary within standard 1206 package tolerances (length 0.122" to 0.126", width 0.063", height 0.024" to 0.028")
• Manufacturer-specific features (anti-sulfur, moisture resistant, automotive AEC-Q200 certification) do not disqualify substitution but represent additional capabilities
• Packaging format (Tape & Reel vs. bulk) does not affect electrical equivalence
• Product status variations (Active vs. Not For New Designs) affect long-term availability but not immediate substitution validity

All five substitute parts listed meet these mandatory matching criteria and are therefore direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, General Applications): RC1206FR-07787RL (YAGEO) or RMCS1206FT787R (Stackpole) are recommended for new designs and ongoing production. Both parts maintain Active product status, ensuring long-term availability and manufacturer support. RC1206FR-07787RL offers moisture-resistant properties matching the original specification. RMCS1206FT787R provides anti-sulfur characteristics equivalent to the RCS3216F7870CS primary part.

Automotive Applications: AC1206FR-07787RL (YAGEO) or CRCW1206787RFKEA (Vishay Dale) are suitable when AEC-Q200 automotive qualification is required. Both parts carry this certification and maintain Active status. CRCW1206787RFKEA offers the lowest maximum height (0.024"), which may be advantageous in space-constrained automotive PCB designs.

Legacy or Existing Inventory Utilization: ERJ-8ENF7870V (Panasonic) is electrically and mechanically equivalent but carries Not For New Designs status. This part is suitable for replacement in existing equipment or when existing inventory must be consumed. The higher maximum height (0.028") should be verified against PCB clearance requirements.

Compliance Verification: All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. MSL rating of 1 (Unlimited) applies uniformly across all options, eliminating moisture sensitivity as a selection differentiator.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F7870CS with any of these parts without circuit redesign?

A: Yes. All listed substitute parts are direct electrical and mechanical equivalents. They share identical resistance value (787 Ohms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No circuit redesign is required.

Q: What is the difference between "Active" and "Not For New Designs" product status?

A: Active status indicates the manufacturer continues production and supports the part for new designs. Not For New Designs (ERJ-8ENF7870V) indicates the manufacturer has discontinued new production but may still supply existing inventory. For new product development, select parts with Active status. For replacement or repair of existing equipment, Not For New Designs parts are acceptable if inventory is available.

Q: Do the physical dimension variations matter for PCB compatibility?

A: Physical dimensions vary within standard 1206 package tolerances. Length ranges from 0.122" to 0.126", and height ranges from 0.024" to 0.028". These variations are within standard 1206 specifications and do not affect PCB footprint compatibility. However, verify maximum height clearance if the PCB has space constraints above the resistor location.

Q: What is the significance of "Anti-Sulfur" and "Moisture Resistant" features?

A: Anti-sulfur protection prevents corrosion from sulfur-containing environmental contaminants, extending component life in industrial or harsh environments. Moisture resistance reduces performance degradation in high-humidity conditions. These are additional protective features that do not affect basic electrical equivalence. Select based on environmental requirements of the application.

Q: Are automotive-qualified parts (AEC-Q200) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts (AC1206FR-07787RL, CRCW1206787RFKEA, ERJ-8ENF7870V) meet or exceed general industrial specifications. They can be used in non-automotive applications without restriction. AEC-Q200 certification indicates enhanced reliability testing and is not a limitation for other applications.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity level restriction. These parts do not require special dry-pack storage, desiccant handling, or bake-out procedures before soldering. Standard warehouse storage conditions are acceptable.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different manufacturers in the same batch does not affect circuit performance. However, for traceability and quality control purposes, many manufacturers prefer single-source parts per production lot.

Q: Which substitute offers the best long-term availability?

A: RC1206FR-07787RL (YAGEO) and RMCS1206FT787R (Stackpole) both carry Active status with substantial inventory levels (59,826 and 1,078 units respectively). YAGEO's RC1206FR-07787RL offers the highest inventory position, supporting extended production runs without supply interruption.
