RC3216F3573CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F3573CS is a 357 kOhms ±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 1106 pieces currently in stock. The RC series resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. Substitute parts become necessary when primary inventory is depleted, when specific certifications are required for application compliance, or when alternative sourcing improves supply chain resilience.

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F3573CS is determined by strict electrical and mechanical parameter matching. All substitute parts must satisfy the following criteria:

Mandatory Matching Parameters:

Resistance value: 357 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Terminations: 2
RoHS compliance: ROHS3 Compliant
MSL rating: 1 (Unlimited)

Allowable Variations: Physical dimensions (length, width, height) may vary within manufacturer specifications while maintaining 1206 package classification. Product status (Active, Not For New Designs, Discontinued) does not disqualify substitution but affects long-term availability. Additional certifications such as AEC-Q200 automotive qualification represent enhanced specifications and do not prevent substitution in non-automotive applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

RC1206FR-07357KL (YAGEO) and RMCF1206FT357K (Stackpole Electronics Inc) are recommended as primary alternatives. Both maintain Active product status, ensuring continued availability and manufacturer support. RMCF1206FT357K includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability standards.

Secondary Substitutes (Active Status with Enhanced Certifications):

CRCW1206357KFKEA (Vishay Dale) and KTR18EZPF3573 (Rohm Semiconductor) are Active products with AEC-Q200 automotive certification. KTR18EZPF3573 additionally features high voltage capability. These components are suitable for automotive and industrial applications requiring enhanced qualification documentation.

Limited Availability Substitutes:

ERJ-8ENF3573V (Panasonic Electronic Components) carries "Not For New Designs" status, indicating manufacturer phase-out. This part remains electrically and mechanically compatible but should be avoided for new product development.

MCR18ERTF3573 (Rohm Semiconductor) is discontinued at DiGi Electronics, limiting procurement channels. Use only when existing inventory is available and alternative sourcing is not feasible.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F3573CS with any of these parts in my existing design?

A: Yes. All listed substitute parts meet the mandatory electrical and mechanical parameters: 357 kOhms ±1%, 0.25W, 1206 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. Physical dimension variations within 1206 package specifications do not affect circuit performance.

Q: What is the difference between parts marked "Active" and "Not For New Designs"?

A: "Active" status indicates the manufacturer continues production and provides full technical support. "Not For New Designs" indicates the manufacturer is phasing out the product; existing inventory may be available but future procurement is uncertain. For new designs, select only Active status parts.

Q: Do AEC-Q200 certified parts work in non-automotive applications?

A: Yes. AEC-Q200 certification represents enhanced reliability testing and qualification beyond standard requirements. Parts with AEC-Q200 certification are fully compatible in non-automotive applications and provide superior reliability margins.

Q: Are there any physical dimension differences I should consider?

A: All parts are classified as 1206 (3216 Metric) package. Seated heights vary between 0.024" (0.60mm) and 0.028" (0.70mm), and length dimensions range from 0.120" to 0.126". These variations are within standard 1206 package tolerances and do not affect PCB layout or assembly processes.

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

A: RC1206FR-07357KL (YAGEO) and RMCF1206FT357K (Stackpole Electronics Inc) both maintain Active status with substantial inventory levels (18,728 and 2,332 pieces respectively). YAGEO typically maintains longer production lifecycles for standard resistor values.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All substitute parts are pin-compatible with identical termination count (2), package footprint classification (1206), and electrical specifications. No circuit modifications or PCB redesign is required for substitution.
