RCS3216F155CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F155CS is a 1.5 MOhms ±1% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with anti-sulfur and moisture-resistant characteristics. The part operates across -55°C to 155°C temperature range and complies with ROHS3 standards.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or when design requirements mandate alternative certifications such as automotive AEC-Q200 qualification. The substitute parts listed maintain electrical and mechanical compatibility while offering equivalent functional performance.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters (Must Match Exactly):

• Resistance value: 1.5 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All four substitute parts listed meet these criteria. Variations in physical dimensions (length, width, height) and packaging format (Tape & Reel versus Cut Tape) do not affect electrical or functional compatibility. Additional certifications such as AEC-Q200 automotive qualification represent enhanced specifications that do not preclude substitution.

Engineering Selection Recommendations

Primary Selection (Preferred): RCS3216F155CS remains the primary choice when Samsung Electro-Mechanics supply is available. This part carries Active product status with established manufacturing continuity.

Secondary Selection (Recommended Alternatives):

AC1206FR-071M5L (YAGEO) and RC1206FR-071M5L (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status and are available in high inventory quantities (9,456 and 12,000 units respectively). AC1206FR-071M5L includes automotive AEC-Q200 certification, suitable for applications requiring enhanced reliability qualification. RC1206FR-071M5L provides equivalent performance without automotive certification.

CRCW12061M50FKEA (Vishay Dale) is a qualified substitute with the highest inventory availability (27,628 units) and Active product status. This part includes AEC-Q200 automotive qualification and is suitable for automotive and industrial applications.

Tertiary Selection (Limited Use): ERJ-8ENF1504V (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" product status. This part is suitable only for legacy system maintenance or replacement applications where design freeze conditions apply. New design implementations should avoid this part number.

Frequently Asked Questions (FAQ)

Q: Can RCS3216F155CS be directly replaced with AC1206FR-071M5L?

A: Yes. Both parts share identical electrical specifications (1.5 MOhms ±1%, 0.25W, ±100ppm/°C) and mechanical form factor (1206 package). AC1206FR-071M5L includes additional AEC-Q200 automotive certification, which does not create incompatibility. Direct substitution is electrically and mechanically valid.

Q: What is the difference between AC1206FR-071M5L and RC1206FR-071M5L?

A: Both are YAGEO 1206 resistors with identical electrical parameters. AC1206FR-071M5L includes AEC-Q200 automotive qualification; RC1206FR-071M5L does not. For non-automotive applications, RC1206FR-071M5L is functionally equivalent. For automotive applications, AC1206FR-071M5L is the appropriate selection.

Q: Why is ERJ-8ENF1504V marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued active development and recommends alternative parts for new product designs. The part remains electrically and mechanically compatible but should not be selected for new circuit designs. Use only for legacy system support.

Q: Are packaging format differences (Tape & Reel versus Cut Tape) significant?

A: No. Packaging format affects only procurement and assembly logistics, not electrical or mechanical compatibility. Tape & Reel (TR) packaging is standard for high-volume automated assembly; Cut Tape (CT) is suitable for lower-volume or manual assembly. Both formats contain identical components.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts are pin-compatible with identical 1206 package footprints. PCB layout modifications are not required. Component placement and soldering procedures remain unchanged.

Q: What inventory considerations apply to substitute selection?

A: CRCW12061M50FKEA (Vishay Dale) offers the highest inventory availability at 27,628 units. AC1206FR-071M5L and RC1206FR-071M5L (YAGEO) provide 9,456 and 12,000 units respectively. Supply chain strategy should prioritize parts with highest inventory levels to minimize lead time risk.
