RC5025F34R8CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F34R8CS is a 34.8 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with a power rating of 0.667W (2/3W). This component is classified as Active product status and features moisture-resistant construction suitable for general industrial applications. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when alternative manufacturers offer components with matching electrical specifications and compatible mechanical packaging. Substitute parts in this reference maintain identical resistance value, tolerance, package dimensions, and operating temperature range while potentially offering different power ratings, automotive qualifications, or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F34R8CS are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 34.8 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Physical dimensions: 5.00mm L x 2.50mm W
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Power rating (0.667W vs. 0.75W)
• Manufacturer and series designation
• Packaging format (bulk vs. Tape & Reel)
• Product status (Active vs. Not For New Designs)
• Automotive qualification (AEC-Q200)
• Specific features (Moisture Resistant vs. Automotive AEC-Q200)

Substitute parts identified in this reference meet all mandatory matching parameters and are therefore electrically and mechanically compatible with the RC5025F34R8CS in applications where the specified power rating is not exceeded.

Parameter Comparison

Engineering Selection Recommendations

CRCW201034R8FKEF (Vishay Dale) is the primary substitute for new designs. This part maintains Active product status, meets all electrical and mechanical compatibility requirements, and carries AEC-Q200 automotive qualification. The 0.75W power rating provides increased thermal margin compared to the 0.667W RC5025F34R8CS. Packaging is supplied in Tape & Reel format with 6610 units in stock.

ERJ-12SF34R8U (Panasonic Electronic Components) is a secondary substitute option. While electrically and mechanically compatible with identical electrical parameters, this part carries a "Not For New Designs" product status designation. The 0.75W power rating and AEC-Q200 automotive qualification are present. This part should be used only for replacement or legacy system applications where design continuity is required. Inventory availability is 15264 units in Tape & Reel packaging.

For applications requiring Active product status and ongoing manufacturer support, CRCW201034R8FKEF is the recommended selection. For legacy or replacement applications, ERJ-12SF34R8U remains electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can CRCW201034R8FKEF replace RC5025F34R8CS in existing designs?

A: Yes. CRCW201034R8FKEF is electrically and mechanically compatible. Both parts share identical resistance (34.8 Ohms), tolerance (±1%), package (2010/5025 Metric), composition (Thick Film), temperature coefficient (±100 ppm/°C), and operating temperature range (-55°C to 155°C). The substitute has a higher power rating (0.75W vs. 0.667W), which provides additional thermal capability. Physical dimensions are identical (5.00 x 2.50 mm), ensuring PCB layout compatibility.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: The power rating indicates the maximum continuous power dissipation the resistor can handle. CRCW201034R8FKEF (0.75W) has a higher power dissipation capability than RC5025F34R8CS (0.667W). In applications where the RC5025F34R8CS operates below its 0.667W limit, the CRCW201034R8FKEF substitute will operate with additional thermal margin. No circuit redesign is required.

Q: Why is ERJ-12SF34R8U marked "Not For New Designs"?

A: "Not For New Designs" is a product lifecycle designation indicating that Panasonic is not actively promoting this part for new circuit designs. However, the part remains electrically and mechanically compatible and is suitable for replacement applications or legacy system support. For new designs, CRCW201034R8FKEF (Active status) is the preferred selection.

Q: Are the substitute parts AEC-Q200 qualified?

A: Yes. Both CRCW201034R8FKEF and ERJ-12SF34R8U carry AEC-Q200 automotive qualification. The RC5025F34R8CS does not list AEC-Q200 qualification. If automotive-grade components are required, the substitute parts provide this additional qualification.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. All three parts use the 2010 (5025 Metric) package with identical physical dimensions of 5.00 x 2.50 mm. The maximum seated height differs slightly (RC5025F34R8CS: 0.66 mm; CRCW201034R8FKEF and ERJ-12SF34R8U: 0.70 mm), but this 0.04 mm difference is within standard PCB assembly tolerances and does not affect footprint compatibility.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All three parts share this MSL 1 rating, eliminating any moisture management concerns during substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC5025F34R8CS, CRCW201034R8FKEF, and ERJ-12SF34R8U are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
