RC3225F3650CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F3650CS is a 365 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation with a moisture-resistant design and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and resistance value, allowing direct replacement in circuit designs without layout modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F3650CS is determined by the following mandatory parameters:

Electrical Equivalence Requirements:

• Resistance value: 365 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)

Mechanical Compatibility Requirements:

• Package / Case: 1210 (3225 Metric) footprint (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Requirements:

• RoHS3 Compliant status
• MSL 1 rating

Power Rating Consideration: Substitute parts may have equal or higher power ratings (0.333W or greater) while maintaining identical footprint dimensions. Higher power ratings do not affect substitutability in applications designed for the RC3225F3650CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW1210365RFKEA (Vishay Dale)

The CRCW1210365RFKEA maintains Active product status with full electrical and mechanical equivalence to the RC3225F3650CS. This part provides identical resistance, tolerance, temperature coefficient, and operating temperature specifications within the 1210 package footprint. The higher power rating (0.5W versus 0.333W) presents no compatibility issues for applications designed around the RC3225F3650CS. AEC-Q200 automotive qualification provides additional reliability assurance. Tape & Reel packaging supports high-volume production workflows.

Secondary Substitute: ERJ-14NF3650U (Panasonic Electronic Components)

The ERJ-14NF3650U meets all electrical and mechanical substitution criteria with identical core specifications. However, this part carries a "Not For New Designs" product status designation, indicating Panasonic has discontinued active development and support. This classification restricts use to legacy system maintenance and repair applications only. New circuit designs should prioritize the CRCW1210365RFKEA alternative.

Both substitute parts maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and full compatibility with the RC3225F3650CS footprint and electrical performance envelope.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210365RFKEA replace RC3225F3650CS in existing designs?

A: Yes. Both parts share identical resistance (365 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 1210 package footprint. The higher power rating of CRCW1210365RFKEA (0.5W) does not affect compatibility in circuits designed for 0.333W operation.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF3650U?

A: This designation indicates Panasonic has transitioned this part to end-of-life status and no longer recommends it for new product development. While the part remains electrically and mechanically equivalent, it should be reserved for repair and maintenance of existing systems only. New designs should specify CRCW1210365RFKEA or RC3225F3650CS.

Q: Are there package format differences between these substitutes?

A: RC3225F3650CS is supplied in bulk packaging, while CRCW1210365RFKEA and ERJ-14NF3650U are supplied in Tape & Reel format. Both packaging formats contain identical components; the difference reflects manufacturing and distribution methods. Tape & Reel format supports automated assembly processes.

Q: Do all three parts meet the same compliance standards?

A: Yes. RC3225F3650CS, CRCW1210365RFKEA, and ERJ-14NF3650U all maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and REACH unaffected status. CRCW1210365RFKEA and ERJ-14NF3650U additionally carry AEC-Q200 automotive qualification.

Q: What determines whether a part can substitute for RC3225F3650CS?

A: Substitution requires exact matching of resistance value (365 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), package footprint (1210 / 3225 Metric), composition (thick film), and compliance certifications (ROHS3, MSL 1). Power rating may be equal or higher without affecting substitutability.
