RCS3216J435CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216J435CS is a 4.3 MOhms ±5% 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 is RoHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package format, resistance value, and power rating. Alternative sources provide equivalent functionality for applications requiring component availability, supply chain flexibility, or specific certification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

• Resistance value: 4.3 MOhms (exact match required)
• Package format: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: RoHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (Unlimited) (exact match required)

Secondary Compatibility Consideration:

• Tolerance: ±5% (main part specification) or ±1% (tighter tolerance acceptable for direct substitution)

All identified substitute parts maintain identical electrical performance within the specified operating conditions and mechanical compatibility with the original 1206 package footprint.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Identical Tolerance):

RC1206JR-074M3L (YAGEO) provides direct substitution with matching ±5% tolerance specification. This part maintains all electrical and mechanical parameters identical to the RCS3216J435CS. Both components are Active status with RoHS3 compliance and MSL 1 rating. Selection of this substitute is appropriate when component availability or supply chain requirements necessitate alternative sourcing.

Upgraded Substitution (Tighter Tolerance):

KTR18EZPF4304 (Rohm Semiconductor) and RC1206FR-074M3L (YAGEO) both feature ±1% tolerance, representing improved accuracy compared to the ±5% specification of the main part. These components maintain all other electrical parameters and mechanical compatibility. The tighter tolerance does not introduce incompatibility; circuits designed for ±5% tolerance operate within specification with ±1% components. Both parts are Active status with RoHS3 compliance and MSL 1 rating.

KTR18EZPF4304 carries AEC-Q200 automotive qualification, applicable for applications requiring automotive-grade component certification.

Compliance Verification:

All substitute parts maintain RoHS3 compliance, REACH unaffected status, and identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications as the original component.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-074M3L replace RCS3216J435CS in my circuit?

A: Yes. RC1206FR-074M3L is a direct substitute. Both components share identical resistance (4.3 MOhms), power rating (0.25W), package (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance ratings (RoHS3, MSL 1). The ±1% tolerance of RC1206FR-074M3L is tighter than the ±5% specification of RCS3216J435CS, which does not create incompatibility.

Q: What is the difference between RC1206JR-074M3L and RC1206FR-074M3L?

A: Both are YAGEO 1206 package 4.3 MOhms thick film resistors with identical electrical specifications and operating parameters. The primary difference is tolerance: RC1206JR-074M3L carries ±5% tolerance (matching the main part), while RC1206FR-074M3L carries ±1% tolerance. Both are suitable substitutes for RCS3216J435CS.

Q: Is KTR18EZPF4304 suitable for non-automotive applications?

A: Yes. KTR18EZPF4304 meets all electrical and mechanical requirements for direct substitution. The AEC-Q200 automotive qualification is an additional certification that does not restrict use in non-automotive applications. All electrical parameters, package dimensions, and compliance ratings are identical to RCS3216J435CS.

Q: Do all substitute parts have the same physical dimensions?

A: All substitute parts use the 1206 (3216 Metric) package with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). Height specifications are equivalent: RCS3216J435CS maximum 0.026" (0.66mm), KTR18EZPF4304 maximum 0.026" (0.65mm), and YAGEO parts maximum 0.026" (0.65mm). These dimensional tolerances are within standard PCB assembly specifications.

Q: Are all parts RoHS3 compliant?

A: Yes. RCS3216J435CS, KTR18EZPF4304, RC1206FR-074M3L, and RC1206JR-074M3L are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Can I use a ±1% tolerance part where ±5% is specified?

A: Yes. Tighter tolerance components (±1%) are compatible with circuits designed for ±5% tolerance. The ±1% specification represents improved accuracy and does not introduce circuit incompatibility. KTR18EZPF4304 and RC1206FR-074M3L both provide this upgraded tolerance specification.
