RCS3216F3832CS Equivalent & Substitute Parts

Part Overview

The RCS3216F3832CS is a 38.3 kOhms ±1% 0.25W Chip Resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This component is actively produced and widely available in inventory. Identifying equivalent and substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design continuity when the primary manufacturer's stock becomes constrained or when alternative sourcing strategies are required.

Substitute Part Grouping Explanation

Substitution of the RCS3216F3832CS is determined by strict adherence to the following critical parameters:

Mandatory Equivalence Parameters:

Resistance value: 38.3 kOhms (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 ~ 155°C (exact match required)
RoHS compliance: ROHS3 Compliant (minimum requirement)
Moisture sensitivity: MSL 1 (acceptable)

All four identified substitute parts meet these mandatory parameters and are therefore electrically and mechanically interchangeable with the primary component.

Engineering Selection Recommendations

Primary Substitutes (Active Products):

CR1206-FX-3832ELF (Bourns Inc.): Recommended for general applications. Active product status ensures long-term availability. Height specification is within acceptable mechanical tolerance for 1206 packages.
CRCW120638K3FKEA (Vishay Dale): Recommended for automotive applications. AEC-Q200 qualification provides additional reliability assurance. Lowest seated height (0.60mm) suitable for space-constrained layouts.
RC1206FR-0738K3L (YAGEO): Recommended for cost-optimized designs. Active product status with established supply chain presence. Dimensions closely match the primary component.

Secondary Substitute (Not For New Designs):

ERJ-8ENF3832V (Panasonic Electronic Components): Electrically equivalent and AEC-Q200 qualified. Product status "Not For New Designs" indicates the manufacturer is discontinuing this part line. Suitable only for legacy design updates or existing inventory consumption.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically identical to the RCS3216F3832CS? A: Yes. All four substitute parts maintain the same resistance value (38.3 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). They are electrically interchangeable.

Q: Why do seated heights vary among substitutes? A: Seated height variation (0.024" to 0.030") is within manufacturing tolerances for 1206 package components and does not affect electrical performance. Height differences are mechanical only and relevant only for applications with strict vertical clearance constraints.

Q: Can ERJ-8ENF3832V be used in new designs? A: The product status "Not For New Designs" indicates Panasonic recommends against using this part in new designs. It is acceptable only for legacy systems or in applications where existing inventory must be consumed. Use CR1206-FX-3832ELF, CRCW120638K3FKEA, or RC1206FR-0738K3L for new designs.

Q: What is the significance of AEC-Q200 qualification on CRCW120638K3FKEA? A: AEC-Q200 qualification indicates automotive-grade reliability and is applicable to automotive, industrial, and high-reliability applications. This qualification is not required for commercial applications but provides additional quality assurance when needed.

Q: Are all parts RoHS3 compliant? A: Yes. All five parts (primary and substitutes) are ROHS3 compliant, ensuring compliance with environmental and hazardous substance restrictions.

Q: Which substitute offers the best inventory availability? A: CR1206-FX-3832ELF (Bourns) has the highest reported inventory (19,705 pcs), followed by ERJ-8ENF3832V (Panasonic) with 60,432 pcs. However, Panasonic's "Not For New Designs" status suggests inventory is being wound down.
