RCS3216F3831CS Equivalent & Substitute Parts

Part Overview

The RCS3216F3831CS is a 3.83 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 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 environmental ratings align with the original component, enabling direct replacement in circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3831CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

Resistance value: 3.83 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C

Critical Mechanical Parameters:

Package type: 1206 (3216 Metric)
Number of terminations: 2
Physical dimensions compatible with 1206 footprint

Compliance & Environmental Parameters:

RoHS3 compliance
Moisture Sensitivity Level: 1 (Unlimited)
REACH unaffected status

All identified substitute parts meet these criteria. Variations in height-seated maximum and exact length/width dimensions within the 1206 package specification do not preclude substitution, as these fall within standard 1206 tolerances.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-3831ELF (Bourns Inc.), CRCW12063K83FKEA (Vishay Dale), RC1206FR-073K83L (YAGEO), and RMCF1206FT3K83 (Stackpole Electronics Inc) are all suitable direct replacements. All four maintain active production status, ROHS3 compliance, and identical electrical specifications. Selection among these options may be based on availability, packaging format (Tape & Reel), or supply chain preference.

Secondary Substitute (Legacy Status):

ERJ-8ENF3831V (Panasonic Electronic Components) meets all electrical and mechanical substitution criteria and maintains ROHS3 compliance with MSL 1 rating. However, this part carries a "Not For New Designs" product status designation. Use of this substitute is limited to replacement applications in existing designs or where supply constraints necessitate legacy component selection.

Compliance Alignment:

All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030, matching the original RCS3216F3831CS regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can I substitute CR1206-FX-3831ELF for RCS3216F3831CS in my circuit?

A: Yes. CR1206-FX-3831ELF meets all critical electrical parameters (3.83 kΩ ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (1206 package, 2 terminations). Both components are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the substitute parts listed?

A: All substitute parts share identical electrical specifications and package type. Differences exist only in manufacturer, height-seated maximum dimension (ranging 0.60mm to 0.75mm within 1206 tolerance), and product status. CR1206-FX-3831ELF, CRCW12063K83FKEA, RC1206FR-073K83L, and RMCF1206FT3K83 are active products. ERJ-8ENF3831V is designated "Not For New Designs."

Q: Why is ERJ-8ENF3831V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development for new applications. The part remains functionally equivalent and available in inventory but should not be selected for new circuit designs. Use only for replacement or legacy system maintenance.

Q: Are there any height or dimensional concerns when substituting?

A: All substitute parts conform to the 1206 (3216 Metric) package specification. Height-seated maximum values range from 0.60mm to 0.75mm, all within standard 1206 tolerances. PCB footprint compatibility is maintained across all substitutes.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All substitute parts, including the original RCS3216F3831CS, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute offers the best availability?

A: CRCW12063K83FKEA (Vishay Dale) shows the highest inventory level at 28,036 pieces, followed by ERJ-8ENF3831V (Panasonic) at 68,980 pieces. CR1206-FX-3831ELF (Bourns) maintains 25,563 pieces in stock.
