Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3225F36R5CS are qualified based on the following critical parameters:

Primary Matching Criteria:

• Resistance value: 36.5 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Terminations: 2
• RoHS and REACH compliance status

Secondary Consideration: Power rating may vary between 0.333W and 0.5W. Higher power-rated substitutes (0.5W) are functionally compatible in applications designed for the 0.333W specification, as they provide equivalent or superior thermal performance within the same package footprint.

All identified substitutes maintain identical electrical specifications for resistance and tolerance, ensuring direct replacement capability in circuit designs without performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The CRCW121036R5FKEA from Vishay Dale is the recommended substitute for new designs. This part maintains Active product status, ensuring long-term availability and supply chain stability. It provides 0.5W power rating within the same 1210 package, offering improved thermal margin compared to the original 0.333W specification. The part carries AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating, making it suitable for both commercial and automotive applications.

Alternative Selection (Legacy Status): The ERJ-14NF36R5U from Panasonic Electronic Components is functionally equivalent but carries Not For New Designs product status. This part should be used only for replacement or repair of existing assemblies where supply continuity is required. It provides identical electrical specifications and AEC-Q200 automotive qualification but is not recommended for new circuit development due to its legacy classification.

Compliance Basis: All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Selection between active and legacy parts should prioritize long-term design sustainability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CRCW121036R5FKEA replace RC3225F36R5CS directly? A: Yes. Both parts have identical resistance (36.5 Ohms), tolerance (±1%), package format (1210), composition (thick film), and operating temperature range (-55°C ~ 155°C). The CRCW121036R5FKEA has higher power rating (0.5W vs 0.333W), which provides additional thermal capability without affecting electrical performance in the circuit.

Q: What is the difference between 0.333W and 0.5W power ratings? A: Power rating indicates the maximum continuous power dissipation the resistor can handle. A 0.5W part can safely dissipate more heat than a 0.333W part. In substitution, using a higher-rated part (0.5W) in place of a lower-rated part (0.333W) is acceptable and provides improved thermal margin. The reverse substitution is not recommended.

Q: Are there dimensional compatibility concerns? A: All three parts use the 1210 (3225 Metric) package with nearly identical length (0.126" / 3.20mm). Width varies slightly (0.100" to 0.098"), and height ranges from 0.024" to 0.028". These minor variations are within standard PCB pad tolerances and do not affect mechanical compatibility or soldering.

Q: Why is ERJ-14NF36R5U marked "Not For New Designs"? A: This designation indicates the part is in legacy or end-of-life status. While functionally equivalent and currently in stock, Panasonic does not recommend its use in new product development. For new designs, CRCW121036R5FKEA (Active status) is the preferred choice to ensure long-term supply availability.

Q: Are all parts AEC-Q200 qualified? A: The RC3225F36R5CS does not list AEC-Q200 qualification. Both CRCW121036R5FKEA and ERJ-14NF36R5U carry AEC-Q200 automotive qualification, making them suitable for automotive applications requiring this standard.

Q: What is the significance of MSL 1 (Unlimited) rating? A: Moisture Sensitivity Level 1 means the component has unlimited shelf life and requires no special moisture control during storage or handling. All three parts carry this rating, eliminating moisture-related storage or processing constraints.
