RC5025J124CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025J124CS is a 120 kOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) package. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is suitable for general-purpose applications requiring moisture-resistant thick film construction across the operating temperature range of -55°C to 155°C.

Equivalent and substitute parts are identified when design requirements permit tolerance relaxation, power rating increases, or when alternative manufacturers provide the same electrical and mechanical specifications within allowable parameters for 2010 package chip resistors.

Substitute Part Grouping Explanation

Substitute parts for the RC5025J124CS are classified based on strict adherence to the following substitution criteria:

Mandatory Matching Parameters:

• Resistance value: 120 kOhms (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power Rating: 0.667W or higher (0.75W acceptable as upgrade)
• Manufacturer: Different manufacturers permitted if all mandatory parameters match
• Packaging Format: Tape & Reel acceptable as alternative to standard packaging

Two substitute parts meet these criteria with documented equivalence or upgrade characteristics.

Engineering Selection Recommendations

RC2010JK-07120KL (YAGEO) - Upgrade Substitute:

This part qualifies as a direct upgrade substitute for the RC5025J124CS. The YAGEO RC2010JK-07120KL maintains identical resistance value (120 kOhms), tolerance (±5%), and all mandatory environmental and compliance specifications. The power rating increases from 0.667W to 0.75W, providing enhanced thermal margin without any electrical or mechanical incompatibility. Physical dimensions remain within acceptable tolerance (height 0.65mm vs. 0.66mm). Both parts carry Active product status, ROHS3 compliance, and MSL 1 rating. This substitute is suitable for direct replacement in applications where the original part is specified.

RMCF2010FT120K (Stackpole Electronics Inc) - Similar Substitute:

This part qualifies as a similar substitute with enhanced specifications. The Stackpole RMCF2010FT120K maintains identical resistance value (120 kOhms), package (2010), and all mandatory environmental specifications. The tolerance improves to ±1% (tighter than the ±5% requirement), and power rating increases to 0.75W. The component carries Automotive AEC-Q200 qualification, indicating suitability for automotive-grade applications. Physical height is 0.70mm (within acceptable variation). Both parts carry Active product status, ROHS3 compliance, and MSL 1 rating. This substitute is suitable for applications requiring enhanced tolerance performance or automotive-grade reliability.

Both substitute parts are Active products with full regulatory compliance and equivalent or superior electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can RC2010JK-07120KL replace RC5025J124CS in all applications?

A: Yes. The RC2010JK-07120KL maintains all mandatory electrical and mechanical parameters. The increased power rating (0.75W vs. 0.667W) provides additional thermal capacity without introducing incompatibility. Both parts are ROHS3 compliant, MSL 1, and operate across -55°C to 155°C.

Q: What is the difference between the two substitute parts?

A: RC2010JK-07120KL (YAGEO) maintains ±5% tolerance matching the original part with increased power rating. RMCF2010FT120K (Stackpole) offers tighter ±1% tolerance and includes Automotive AEC-Q200 qualification. Both are functionally equivalent to the main part.

Q: Are there physical compatibility concerns with the substitute parts?

A: No. All three parts use the 2010 (5025 Metric) package with identical length and width (5.00mm x 2.50mm). Height variations (0.65mm to 0.70mm) are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: Do the substitute parts require different handling or storage procedures?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity and handling requirements. Storage and transport procedures are equivalent.

Q: Can RMCF2010FT120K be used in non-automotive applications?

A: Yes. Automotive AEC-Q200 qualification indicates enhanced reliability and stricter manufacturing controls. This part exceeds the requirements for general-purpose applications and is suitable for any application accepting the RC5025J124CS.

Q: What is the impact of tolerance differences on circuit performance?

A: The RC5025J124CS specifies ±5% tolerance. RMCF2010FT120K provides ±1% tolerance, reducing resistance variation from ±6 kOhms to ±1.2 kOhms. This tighter tolerance improves circuit accuracy in applications sensitive to resistance value drift.

Q: Are all substitute parts available in equivalent packaging formats?

A: RC2010JK-07120KL and RMCF2010FT120K are supplied in Tape & Reel (TR) format. The original RC5025J124CS is supplied in standard packaging. Both formats are compatible with automated assembly equipment.
