RC5025F1150CS Equivalent & Substitute Parts

Part Overview

The RC5025F1150CS is a 115 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and features moisture-resistant construction with unlimited moisture sensitivity level (MSL 1). The part is ROHS3 compliant and REACH unaffected, making it suitable for industrial and commercial applications requiring stable resistance values across extended temperature ranges.

Equivalent and substitute parts are identified when components share identical electrical specifications (resistance value, tolerance, temperature coefficient, operating temperature range) and mechanical compatibility (package type, footprint, termination count) while potentially offering different power ratings, packaging formats, or product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1150CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 115 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to 155°C
• Package type: 2010 (5025 Metric)
• Footprint: 5.00mm × 2.50mm
• Termination count: 2
• Composition: Thick Film
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Variable Parameters (Allowable Differences):

• Power rating: Substitute parts may have equal or higher power ratings (0.75W acceptable for 0.667W requirement)
• Packaging format: Original part uses standard packaging; substitutes may use Tape & Reel (TR) format
• Product status: Active or Not For New Designs status acceptable
• Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters align
• Automotive qualification: AEC-Q200 certification is an additional feature, not a requirement for substitution

Two substitute parts meet these criteria: CRCW2010115RFKEF (Vishay Dale) and ERJ-12SF1150U (Panasonic Electronic Components).

Engineering Selection Recommendations

CRCW2010115RFKEF (Vishay Dale) – Primary Substitute

The CRCW2010115RFKEF is the preferred substitute for the RC5025F1150CS. Both components maintain identical electrical specifications (115 Ohms ±1%, ±100 ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (2010 package, 5.00 × 2.50 mm footprint, 2 terminations). The CRCW2010115RFKEF offers a higher power rating (0.75W versus 0.667W), providing additional thermal margin in applications. Both parts are ROHS3 compliant with MSL 1 rating and Active product status. The Vishay Dale part includes AEC-Q200 automotive qualification, which is beneficial for applications requiring automotive-grade reliability. The maximum seated height difference (0.70 mm versus 0.66 mm) is negligible for standard PCB assembly processes.

ERJ-12SF1150U (Panasonic Electronic Components) – Secondary Substitute

The ERJ-12SF1150U is an acceptable substitute with identical electrical and mechanical specifications to the CRCW2010115RFKEF. This Panasonic component shares the same 115 Ohm resistance, ±1% tolerance, ±100 ppm/°C temperature coefficient, and 2010 package configuration. The ERJ-12SF1150U carries AEC-Q200 automotive qualification and ROHS3 compliance. However, this part is designated as "Not For New Designs," indicating that Panasonic has discontinued active development and support for this product line. Selection of ERJ-12SF1150U is appropriate only for legacy system maintenance, repair, or applications where existing inventory must be maintained. For new designs, CRCW2010115RFKEF or the original RC5025F1150CS are preferred.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010115RFKEF be used as a direct replacement for RC5025F1150CS in existing designs?

A: Yes. Both components share identical resistance (115 Ohms), tolerance (±1%), temperature coefficient (±100 ppm/°C), operating temperature range (-55°C to 155°C), and 2010 package footprint (5.00 × 2.50 mm). The CRCW2010115RFKEF has a higher power rating (0.75W versus 0.667W), which is compatible with applications designed for the lower-rated Samsung part. The maximum seated height difference (0.04 mm) does not affect PCB assembly or component clearance in standard designs.

Q: What is the significance of the power rating difference between RC5025F1150CS (0.667W) and the substitute parts (0.75W)?

A: The substitute parts have higher power ratings, meaning they can dissipate more heat without exceeding maximum junction temperature. A component rated for 0.75W can safely operate in applications requiring 0.667W or less. This provides additional thermal margin and does not create compatibility issues. The higher rating does not affect electrical performance or circuit behavior.

Q: Are the substitute parts suitable for automotive applications?

A: Both CRCW2010115RFKEF and ERJ-12SF1150U carry AEC-Q200 automotive qualification, making them suitable for automotive-grade applications. The original RC5025F1150CS does not list automotive qualification. If automotive compliance is required, CRCW2010115RFKEF is the recommended choice due to its Active product status.

Q: Why is ERJ-12SF1150U marked as "Not For New Designs"?

A: "Not For New Designs" indicates that Panasonic has transitioned this product to end-of-life status and is no longer actively supporting new applications. While the part remains functionally equivalent and is available in inventory, it is not recommended for new product development. CRCW2010115RFKEF or RC5025F1150CS should be selected for new designs to ensure long-term supply chain stability and manufacturer support.

Q: Do all three parts have identical moisture sensitivity levels?

A: Yes. RC5025F1150CS, CRCW2010115RFKEF, and ERJ-12SF1150U all have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. All three parts can be stored and handled without special moisture control measures and do not require baking before reflow soldering.

Q: Are there any differences in RoHS or REACH compliance between these parts?

A: No. All three parts are ROHS3 compliant and REACH unaffected, meeting the same environmental and regulatory requirements. They are suitable for applications in regions with strict RoHS and REACH regulations.

Q: What is the maximum height difference between these components, and does it affect PCB design?

A: The RC5025F1150CS has a maximum seated height of 0.66 mm, while both substitute parts have 0.70 mm maximum seated height. The 0.04 mm difference is negligible for standard PCB assembly and does not require design modifications. This height variation is within typical manufacturing tolerances and does not affect component clearance or board-level performance.
