RCS3216F8250CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F8250CS is a 825 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This thick film resistor features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part is currently Active in product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications (825 Ohms resistance, ±1% tolerance, 0.25W power rating), mechanical compatibility (1206 package), and environmental performance characteristics. Substitute parts from alternative manufacturers provide functional equivalence for circuit applications requiring this specific resistance value and power rating.

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F8250CS are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence:

Resistance: 825 Ohms (exact match required)
Tolerance: ±1% (exact match required)
Power Rating: 0.25W / 1/4W (exact match required)
Temperature Coefficient: ±100ppm/°C (exact match required)
Operating Temperature: -55°C to 155°C (exact match required)

Mechanical Equivalence:

Package / Case: 1206 (3216 Metric) (exact match required)
Number of Terminations: 2 (exact match required)

Compliance & Environmental:

RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match required)
Composition: Thick Film (exact match required)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and optional automotive certifications (AEC-Q200) do not affect functional substitutability for standard circuit applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

The following parts are recommended as direct substitutes for the RCS3216F8250CS:

CR1206-FX-8250ELF (Bourns Inc.) – Active product status with moisture-resistant construction matching the original specification
RC1206FR-07825RL (YAGEO) – Active product status with highest inventory availability (177,594 pcs) and moisture-resistant features
RMCF1206FT825R (Stackpole Electronics Inc) – Active product status with automotive AEC-Q200 certification for enhanced reliability in demanding applications
CRCW1206825RFKEA (Vishay Dale) – Active product status with automotive AEC-Q200 certification and established supply chain

Secondary Substitute (Legacy Status):

ERJ-8ENF8250V (Panasonic Electronic Components) – Marked as "Not For New Designs" but functionally equivalent. Use only for replacement or maintenance of existing assemblies where original part sourcing is unavailable.

Automotive Applications:

For applications requiring automotive-grade components, select from parts with AEC-Q200 certification: AC1206FR-07825RL, CRCW1206825RFKEA, ERJ-8ENF8250V, or RMCF1206FT825R.

Supply Chain Considerations:

RC1206FR-07825RL offers the largest inventory position (177,594 pcs), providing supply security for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q1: Can I substitute the RCS3216F8250CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the critical electrical parameters (825 Ohms, ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), package format (1206), and compliance requirements (ROHS3, MSL 1). Direct substitution is electrically and mechanically compatible.

Q2: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. Parts with this certification (AC1206FR-07825RL, CRCW1206825RFKEA, ERJ-8ENF8250V, RMCF1206FT825R) are suitable for automotive applications. Parts without this certification (CR1206-FX-8250ELF, RC1206FR-07825RL) are suitable for general industrial and consumer applications.

Q3: Why is ERJ-8ENF8250V marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued active development of this product line. While the part remains functionally equivalent and available in inventory, it should be used only for replacement or maintenance of existing assemblies. For new designs, select from parts with Active status.

Q4: Are there physical dimension differences between substitute parts?

A: Yes. While all parts conform to the 1206 (3216 Metric) package specification, minor variations exist in seated height: ranging from 0.024" (0.60mm) to 0.030" (0.75mm). These variations are within standard 1206 package tolerances and do not affect PCB footprint compatibility or circuit performance.

Q5: What packaging formats are available?

A: Substitute parts are supplied in two formats: Tape & Reel (TR) for automated assembly and high-volume production, or Cut Tape (CT) with Digi-Reel® for lower-volume applications. Packaging format does not affect electrical or mechanical performance.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting regulatory requirements for hazardous substance restrictions in electronic equipment.

Q7: What does MSL 1 (Unlimited) mean for handling?

A: MSL 1 indicates unlimited shelf life and no special moisture-sensitive device (MSD) handling procedures are required. Parts can be stored and handled under standard industrial conditions without baking or desiccant packaging requirements.
