RCS3216F435CS Equivalent & Substitute Parts

Part Overview

The RCS3216F435CS is a 4.3 MOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F435CS are qualified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Electrical Parameters (Must Match):

• Resistance value: 4.3 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in physical dimensions (length/width within 0.004" tolerance, height within 0.01" tolerance) and packaging format (Tape & Reel vs. bulk) do not affect electrical substitutability.

Parameter Comparison

Engineering Selection Recommendations

RCS3216F435CS (Samsung Electro-Mechanics) - Primary specification. Anti-sulfur and moisture-resistant thick film construction. Active product status with ROHS3 compliance. Suitable for general industrial and consumer applications requiring high-value resistive elements.

KTR18EZPF4304 (Rohm Semiconductor) - Automotive-qualified substitute with AEC-Q200 certification and high-voltage capability. Identical electrical specifications and mechanical compatibility. Recommended for automotive and high-reliability applications where AEC-Q200 qualification is required or preferred. Available in Tape & Reel packaging.

RC1206FR-074M3L (YAGEO) - Moisture-resistant thick film construction with identical electrical parameters. Highest inventory availability (15,734 pcs). Suitable for cost-sensitive applications and high-volume production runs. Available in Tape & Reel packaging. Dimensions within acceptable tolerance (3.10mm length vs. 3.20mm nominal).

All three parts are ROHS3 compliant, MSL 1 rated, and functionally interchangeable in circuit applications requiring 4.3 MOhms ±1% 0.25W resistive elements in 1206 package format.

Frequently Asked Questions (FAQ)

Q: Can KTR18EZPF4304 replace RCS3216F435CS in non-automotive applications?

A: Yes. The KTR18EZPF4304 meets all electrical and mechanical specifications of the RCS3216F435CS. AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits. The part is functionally equivalent.

Q: What is the difference between the packaging formats listed?

A: RCS3216F435CS is available in standard packaging (not specified). KTR18EZPF4304 and RC1206FR-074M3L are supplied in Tape & Reel (TR) format for automated assembly. Both formats contain identical components; packaging format affects handling and assembly process only, not electrical performance.

Q: Are there dimensional differences that affect PCB layout?

A: Dimensional variations are minimal. RCS3216F435CS: 3.20mm L × 1.60mm W. RC1206FR-074M3L: 3.10mm L × 1.60mm W. Height differences (0.66mm vs. 0.65mm) are within standard PCB assembly tolerances. All parts fit standard 1206 footprints without layout modification.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-074M3L (YAGEO) has the highest stock level at 15,734 pcs. KTR18EZPF4304 (Rohm) has 1,910 pcs. RCS3216F435CS (Samsung) has 970 pcs. Availability should be verified with your supplier for current stock status.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Storage and handling requirements are identical across all substitutes.

Q: Is the ±100ppm/°C temperature coefficient critical for substitution?

A: Yes. Temperature coefficient is a key parameter determining substitutability. All qualified substitutes match this specification exactly, ensuring equivalent thermal performance across the -55°C to 155°C operating range.
