RCS3216F3652CS Equivalent & Substitute Parts

Part Overview

The RCS3216F3652CS is a 36.5 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is RoHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

Substitute components are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and form factor), and environmental performance characteristics. Alternative parts enable procurement flexibility, extended supply availability, and design optimization across different manufacturing requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following criteria:

Electrical Parameters: Resistance value (36.5 kOhms), tolerance (±1%), and power dissipation rating (0.25W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package designation (1206 / 3216 Metric) and number of terminations (2) ensure physical and electrical compatibility with PCB layouts and assembly processes.

Environmental & Compliance: RoHS3 compliance, MSL Level 1 rating, and REACH unaffected status confirm regulatory alignment. Composition (thick film) defines manufacturing technology consistency.

All four substitute parts meet these core criteria. Variations in height-seated maximum, specific feature sets (anti-sulfur vs. moisture resistant vs. automotive AEC-Q200), and product status are secondary differentiators for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status):

CR1206-FX-3652ELF (Bourns Inc.) and RC1206FR-0736K5L (YAGEO) are recommended for new designs. Both maintain Active product status with full manufacturer support and long-term availability. CRCW120636K5FKEA (Vishay Dale) is also Active and includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability.

Secondary Selection (Legacy Status):

ERJ-8ENF3652V (Panasonic Electronic Components) carries "Not For New Designs" status. This part remains electrically and mechanically equivalent but should be reserved for legacy system maintenance, repair, or applications where existing qualification data is established.

Compliance Alignment:

All five parts (main and substitutes) are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity. Selection between Active alternatives depends on supply chain requirements, packaging preferences (all available in Tape & Reel), and application-specific certifications (automotive AEC-Q200 available from Vishay Dale and Panasonic).

Frequently Asked Questions (FAQ)

Q: Can I substitute RCS3216F3652CS with any of the listed alternatives without circuit redesign?

A: Yes. All substitute parts match the core electrical parameters (36.5 kOhms ±1%, 0.25W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), and mechanical form factor (1206 package, 2 terminations). Direct PCB footprint compatibility is confirmed.

Q: What is the difference between the anti-sulfur feature on RCS3216F3652CS and moisture-resistant features on other substitutes?

A: Anti-sulfur and moisture-resistant are both environmental protection mechanisms for thick film resistors. The RCS3216F3652CS specifies both anti-sulfur and moisture-resistant properties. Bourns CR1206-FX-3652ELF and YAGEO RC1206FR-0736K5L specify moisture-resistant. All parts maintain MSL Level 1 (Unlimited) rating, indicating equivalent moisture handling capability for standard PCB assembly and storage conditions.

Q: Why is ERJ-8ENF3652V marked "Not For New Designs"?

A: "Not For New Designs" indicates Panasonic has transitioned this part to legacy status. The part remains electrically and mechanically equivalent and is suitable for existing product support and repairs. New product development should prioritize Active-status alternatives: Bourns CR1206-FX-3652ELF, Vishay Dale CRCW120636K5FKEA, or YAGEO RC1206FR-0736K5L.

Q: Does height variation (0.024" to 0.030" seated maximum) affect substitution?

A: Height variation within this range (0.60mm to 0.75mm) is within standard 1206 package tolerance and does not affect PCB assembly compatibility. Verify clearance in high-density layouts or applications with tight vertical constraints.

Q: Which substitute is best for automotive applications?

A: CRCW120636K5FKEA (Vishay Dale) and ERJ-8ENF3652V (Panasonic) both carry AEC-Q200 automotive qualification. CRCW120636K5FKEA is recommended as it maintains Active product status with ongoing manufacturer support.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. All four substitute parts are supplied in Tape & Reel (TR) packaging, standard for automated PCB assembly processes. Inventory availability varies: RC1206FR-0736K5L (YAGEO) has the highest stock level at 156,303 pieces.
