RC5025F1873CS Equivalent & Substitute Parts

Part Overview

The RC5025F1873CS is a 187 kOhms ±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 currently in active production status and features moisture-resistant construction suitable for general industrial applications.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit the use of alternative manufacturers' components that meet or exceed the electrical and mechanical specifications of the original part.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC5025F1873CS is permissible when an alternative component maintains the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 187 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• Composition: Thick Film

Allowable Variation Parameters:

• Power Rating: Substitute components may have equal or higher power ratings (0.667W or greater)
• Physical dimensions: Minor variations within package specification tolerances are acceptable
• Moisture Sensitivity Level: MSL 1 rating or equivalent
• Compliance certifications: May differ based on application requirements

The ERJ-12SF1873U from Panasonic Electronic Components qualifies as a direct substitute based on these criteria, with the exception of product status and compliance differences noted in the engineering selection section.

Engineering Selection Recommendations

RC5025F1873CS (Samsung Electro-Mechanics) - Primary Selection:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliant, meeting current environmental and regulatory requirements
• Suitable for new design implementations and long-term production applications
• Moisture-resistant construction with MSL 1 rating provides reliability in standard industrial environments

ERJ-12SF1873U (Panasonic Electronic Components) - Substitute Selection:

• Electrical parameters match the primary component across all critical specifications
• Higher power rating (0.75W vs. 0.667W) provides additional thermal margin in applications
• AEC-Q200 automotive qualification indicates enhanced reliability testing and quality assurance
• Product status listed as "Not For New Designs" restricts use to legacy system maintenance or replacement applications only
• RoHS non-compliant status may conflict with regulatory requirements in certain markets or end-use applications
• Slightly elevated seated height (0.028" vs. 0.026") requires verification of PCB layout clearance in space-constrained designs

For new design implementations, the RC5025F1873CS is the recommended selection. The ERJ-12SF1873U is suitable only for replacement or repair of existing systems where the original component is unavailable and regulatory compliance permits non-RoHS components.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF1873U be used as a direct replacement for the RC5025F1873CS in new product designs?

A: No. The ERJ-12SF1873U carries a "Not For New Designs" product status designation. While electrical parameters are compatible, this component is restricted to legacy system maintenance and repair applications only. New designs must use the RC5025F1873CS or equivalent active-status components.

Q: What is the significance of the power rating difference (0.667W vs. 0.75W)?

A: The substitute component has a higher power rating, which is acceptable for substitution purposes. A higher power rating indicates greater thermal capacity and does not create incompatibility. The component will operate safely in applications designed for the lower-rated original part.

Q: Does the 0.002" (0.04mm) difference in seated height affect PCB compatibility?

A: The height difference is minimal and falls within standard PCB assembly tolerances for 2010 package components. However, verification is required in designs with tight vertical clearance constraints, such as applications with low-profile enclosures or stacked component arrangements.

Q: Why is RoHS compliance status different between these components?

A: The RC5025F1873CS meets ROHS3 compliance standards, reflecting current environmental regulations. The ERJ-12SF1873U is RoHS non-compliant, indicating it was manufactured under earlier standards. RoHS compliance is mandatory for products sold in the European Union and many other markets. Substitution with a non-compliant component may violate regulatory requirements depending on the end-use application and target market.

Q: What does the AEC-Q200 qualification on the ERJ-12SF1873U indicate?

A: AEC-Q200 is an automotive industry standard qualification that certifies the component has undergone enhanced reliability testing and quality assurance procedures specific to automotive applications. This certification does not affect general industrial use but indicates higher quality assurance standards were applied during manufacturing.

Q: Are there any other substitute parts available for the RC5025F1873CS?

A: The ERJ-12SF1873U is the primary substitute listed for this component. Additional substitutes may exist from other manufacturers; however, only components explicitly listed in the manufacturer's substitution documentation should be considered for direct replacement without additional qualification testing.

Q: What packaging format is the ERJ-12SF1873U supplied in?

A: The ERJ-12SF1873U is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The RC5025F1873CS packaging format is not specified in the provided data. Packaging format differences do not affect electrical or mechanical compatibility but may impact procurement and assembly logistics.
