Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F360CS are classified based on strict electrical and mechanical parameter alignment:

Substitution Criteria:

• Resistance value must equal 36 Ohms
• Tolerance must be ±1% or tighter
• Package must be 1210 (3225 Metric)
• Power rating must be equal to or greater than 0.333W
• Composition must be thick film
• Temperature coefficient must be ±100ppm/°C or better
• Operating temperature range must encompass -55°C ~ 155°C
• RoHS3 compliance required
• MSL rating must be 1 (Unlimited)

Upgrade Substitute: RC1210FR-0736RL (YAGEO) qualifies as an upgrade substitute with identical electrical specifications and increased power rating (0.5W vs. 0.333W), providing enhanced thermal margin while maintaining all other parameters.

Similar Substitute: ERJ-14NF36R0U (Panasonic Electronic Components) meets all electrical and mechanical criteria with additional automotive AEC-Q200 qualification. Product status is listed as "Not For New Designs," limiting its application to legacy or maintenance scenarios.

Parameter Comparison

Engineering Selection Recommendations

RC1210FR-0736RL (YAGEO) - Recommended Upgrade Substitute:

The RC1210FR-0736RL is the primary substitute for new designs and production applications. This part maintains identical electrical specifications (36 Ohms ±1%, thick film, ±100ppm/°C, -55°C ~ 155°C) while providing increased power dissipation capability (0.5W vs. 0.333W). The upgrade in power rating provides additional thermal margin without altering circuit behavior. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance and MSL 1 rating match the original specification. Tape & Reel packaging supports automated assembly processes. Inventory availability (9356 pieces) supports volume production requirements.

ERJ-14NF36R0U (Panasonic) - Legacy/Automotive Applications Only:

The ERJ-14NF36R0U meets all electrical and mechanical substitution criteria and includes automotive AEC-Q200 qualification. However, "Not For New Designs" product status restricts this part to maintenance, repair, and legacy system applications where automotive-grade components are specified. The AEC-Q200 rating provides additional reliability assurance for automotive environments. This part should not be selected for new product development.

Original Part Retention:

The RC3225F360CS remains suitable for applications where Samsung Electro-Mechanics sourcing is specified or preferred. Active product status and adequate inventory (891 pieces) support continued use in existing designs.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-0736RL replace RC3225F360CS in existing designs?

A: Yes. The RC1210FR-0736RL is electrically and mechanically compatible. Both parts share identical resistance (36 Ohms), tolerance (±1%), package (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The increased power rating (0.5W vs. 0.333W) does not affect circuit function and provides additional thermal margin.

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

A: RC1210FR-0736RL (YAGEO) is an upgrade substitute with Active product status suitable for new designs. ERJ-14NF36R0U (Panasonic) includes automotive AEC-Q200 qualification but carries "Not For New Designs" status, limiting use to legacy and maintenance applications.

Q: Are all three parts physically identical?

A: All three parts use the 1210 (3225 Metric) package with identical footprint. Dimensional variations are minor: RC3225F360CS measures 3.20mm x 2.55mm x 0.66mm (max height); RC1210FR-0736RL measures 3.10mm x 2.60mm x 0.60mm (max height); ERJ-14NF36R0U measures 3.20mm x 2.50mm x 0.70mm (max height). These variations fall within standard PCB design tolerances and do not affect placement or soldering.

Q: Do all parts meet RoHS and REACH requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is MSL 1 (Unlimited) and why does it matter?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special dry-pack storage or baking procedures before soldering, simplifying inventory management and assembly processes.

Q: Which part should be selected for new product development?

A: RC1210FR-0736RL (YAGEO) is the recommended choice for new designs. Active product status ensures long-term availability, and the increased power rating provides design margin. RC3225F360CS (Samsung) remains acceptable if Samsung sourcing is specified.

Q: Can ERJ-14NF36R0U be used in new automotive designs?

A: No. The "Not For New Designs" status prohibits use in new product development, including automotive applications. For new automotive designs requiring AEC-Q200 qualification, alternative qualified parts must be sourced.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: This specification defines resistance drift over the operating temperature range (-55°C ~ 155°C). All three parts maintain identical temperature stability, ensuring consistent circuit performance across the full environmental range.
