RC5025F3650CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F3650CS is a 365 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers while meeting the same functional requirements in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following criteria:

Mandatory Matching Parameters:

• Resistance value: 365 Ohms (exact match required)
• Tolerance: ±1% (equal or tighter tolerance acceptable)
• Package / Case: 2010 (5025 Metric) (identical footprint required)
• Composition: Thick Film (same technology class)
• Temperature Coefficient: ±100ppm/°C (equal or better stability)
• Operating Temperature Range: -55°C to 155°C (minimum coverage required)
• RoHS3 Compliance: Required for regulatory equivalence

Acceptable Variation Parameters:

• Power Rating: Minimum 0.667W; higher ratings (0.75W, 1W) are acceptable as they provide thermal margin
• Packaging Format: Tape & Reel (TR) acceptable for production environments; loose form acceptable for prototyping
• Product Status: Active preferred; Not For New Designs acceptable for legacy system support only
• Moisture Sensitivity Level: MSL 1 maintained across all substitutes

The identified substitute parts meet all mandatory parameters while offering equal or superior electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW2010365RFKEF (Vishay Dale)

The CRCW2010365RFKEF maintains Active product status with full RoHS3 compliance and AEC-Q200 automotive qualification. The 0.75W power rating provides thermal margin above the 0.667W requirement of the RC5025F3650CS. Physical dimensions and electrical parameters are equivalent. This part is suitable for new designs and production environments requiring automotive-grade reliability.

Secondary Substitute: ERJ-12SF3650U (Panasonic Electronic Components)

The ERJ-12SF3650U meets all electrical and mechanical compatibility requirements with identical resistance, tolerance, temperature coefficient, and operating range. The 0.75W power rating and AEC-Q200 qualification provide equivalent thermal performance. However, this part carries "Not For New Designs" status, restricting its use to legacy system support, field replacements, and maintenance applications where the original specification must be preserved.

Selection Criteria:

• For new product development: Select CRCW2010365RFKEF (Active status, automotive qualification)
• For legacy system maintenance: ERJ-12SF3650U acceptable where original performance must be maintained
• For applications requiring automotive-grade reliability: Both CRCW2010365RFKEF and ERJ-12SF3650U carry AEC-Q200 certification
• For standard industrial applications: CRCW2010365RFKEF recommended due to Active product status

Frequently Asked Questions (FAQ)

Q: Can the CRCW2010365RFKEF replace the RC5025F3650CS in existing designs?

A: Yes. Both parts share identical resistance (365 Ohms), tolerance (±1%), package (2010/5025 Metric), composition (Thick Film), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The CRCW2010365RFKEF provides higher power rating (0.75W vs. 0.667W), which is acceptable for direct substitution. Physical dimensions are equivalent with maximum seated height difference of 0.002" (0.04mm), which does not affect PCB assembly compatibility.

Q: What is the difference between the Samsung RC5025F3650CS and Vishay CRCW2010365RFKEF?

A: The primary differences are manufacturer, power rating (0.667W vs. 0.75W), and packaging format. The Vishay part includes AEC-Q200 automotive qualification and maintains Active product status. Electrical performance, tolerance, temperature stability, and environmental operating range are identical. The higher power rating of the Vishay part provides additional thermal margin without affecting circuit function.

Q: Why is the Panasonic ERJ-12SF3650U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active development and promotion of this part number. While the part remains functionally equivalent and available in inventory, it is restricted to legacy applications, field replacements, and maintenance of existing systems. New product development should specify the CRCW2010365RFKEF or equivalent Active-status alternatives.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RC5025F3650CS, CRCW2010365RFKEF, and ERJ-12SF3650U all carry ROHS3 Compliant status, meeting EU Directive 2011/65/EU requirements for restricted substances. All parts are suitable for markets requiring RoHS compliance.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level with unlimited shelf life under standard storage conditions (typically 30°C / 60% relative humidity). No special moisture-barrier packaging, desiccant storage, or bake-out procedures are required before assembly. All three parts share this classification, eliminating moisture-related handling constraints.

Q: Can the substitute parts be used in automotive applications?

A: The CRCW2010365RFKEF and ERJ-12SF3650U both carry AEC-Q200 automotive qualification, meeting automotive industry reliability and qualification standards. The RC5025F3650CS does not specify AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, the Vishay CRCW2010365RFKEF is the recommended choice.

Q: What is the maximum height difference between these parts?

A: The RC5025F3650CS has a maximum seated height of 0.026" (0.66mm), while both substitute parts have maximum seated heights of 0.028" (0.70mm). The difference of 0.002" (0.04mm) is within typical PCB assembly tolerances and does not affect component placement, solder joint formation, or clearance to adjacent components in standard 2010 package designs.

Q: Are there any REACH or ECCN restrictions on these parts?

A: All three parts carry identical REACH Status (REACH Unaffected) and ECCN classification (EAR99), indicating no additional export control or chemical substance restrictions beyond standard RoHS3 compliance. These parts are suitable for unrestricted commercial distribution in compliant markets.
