RC3216F5230CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F5230CS is a 523 Ohms ±1% 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 611 pieces currently in stock. The part is designed for general-purpose applications requiring moisture-resistant thick film construction 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 without functional degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F5230CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (523 Ohms), tolerance (±1%), and power rating (0.25W) must be identical across all substitute parts.

Package Compatibility: All substitute parts must use the 1206 (3216 Metric) package with 2 terminations to ensure PCB footprint compatibility.

Environmental Ratings: Operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C) must match the original specification.

Compliance Standards: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to satisfy regulatory and manufacturing requirements.

Composition: Thick film construction is maintained across all substitute options.

The substitute parts identified—ERJ-8ENF5230V, RC1206FR-07523RL, RMCF1206FT523R, and CRCW1206523RFKEA—satisfy all these criteria and are therefore electrically and mechanically interchangeable with the RC3216F5230CS.

Engineering Selection Recommendations

Primary Selection: RC1206FR-07523RL (YAGEO) and RMCF1206FT523R (Stackpole Electronics Inc) are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and continued manufacturer support. YAGEO offers the highest inventory level among active alternatives at 15,226 pieces.

Secondary Selection: CRCW1206523RFKEA (Vishay Dale) is an active alternative with 5,841 pieces in stock, suitable for applications requiring established supply chain relationships with Vishay.

Legacy Consideration: ERJ-8ENF5230V (Panasonic Electronic Components) carries "Not For New Designs" status despite high inventory availability (152,575 pieces). This designation indicates the manufacturer is phasing out this product line. Use only when existing designs require continuity or when new design qualification is not applicable.

All substitute parts maintain identical electrical specifications, package dimensions, operating temperature ranges, and compliance certifications (ROHS3, MSL 1) as the original RC3216F5230CS.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF5230V replace RC3216F5230CS in new designs?

A: ERJ-8ENF5230V carries "Not For New Designs" status from Panasonic. While electrically and mechanically equivalent, this designation indicates the manufacturer is discontinuing the product line. For new designs, select from active alternatives: RC1206FR-07523RL, RMCF1206FT523R, or CRCW1206523RFKEA.

Q: Are there dimensional differences between substitute parts?

A: All substitute parts use the 1206 (3216 Metric) package. Minor variations exist in maximum seated height: RC3216F5230CS and RC1206FR-07523RL specify 0.026" (0.65mm), while ERJ-8ENF5230V, RMCF1206FT523R, and CRCW1206523RFKEA specify 0.028", 0.028", and 0.024" respectively. These variations remain within standard PCB assembly tolerances and do not affect interchangeability.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RC3216F5230CS specification.

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: "Direct" substitutes (ERJ-8ENF5230V, RC1206FR-07523RL, RMCF1206FT523R) are electrically and mechanically identical to the original part. "Similar" substitutes (CRCW1206523RFKEA) meet all critical electrical and mechanical parameters but may originate from different manufacturer design families. All are functionally interchangeable.

Q: Which substitute offers the best long-term availability?

A: RC1206FR-07523RL (YAGEO) with Active status and 15,226 pieces in inventory provides the strongest availability position. RMCF1206FT523R (Stackpole) and CRCW1206523RFKEA (Vishay) also maintain Active status with adequate stock levels (2,754 and 5,841 pieces respectively).
