Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F184CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 180 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) are acceptable as this represents a higher power capability within the same package footprint, providing equal or superior performance in the same thermal and spatial constraints.

The identified substitute parts CRCW2010180KFKEF (Vishay Dale) and RMCF2010FT180K (Stackpole Electronics Inc) meet all critical parameters with an increased power rating of 0.75W, maintaining identical package dimensions, resistance value, tolerance, and temperature characteristics.

Parameter Comparison

Engineering Selection Recommendations

RC5025F184CS (Samsung Electro-Mechanics): Primary selection for moisture-resistant applications. Active product status with established supply chain. RoHS3 compliant and REACH unaffected. Suitable for general industrial and consumer electronics applications requiring standard thick film resistor performance.

CRCW2010180KFKEF (Vishay Dale): Qualified substitute with automotive AEC-Q200 certification. Higher power rating (0.75W) provides thermal margin in the same package footprint. Active product status with robust inventory availability (8891 Pcs). Recommended for applications requiring automotive-grade reliability or where thermal headroom is beneficial.

RMCF2010FT180K (Stackpole Electronics Inc): Qualified substitute with automotive AEC-Q200 certification. Identical electrical and thermal specifications to CRCW2010180KFKEF. Active product status. Recommended as secondary alternative when primary substitute availability is constrained.

All three parts maintain identical compliance certifications (RoHS3, REACH unaffected, EAR99 ECCN classification) and are suitable for direct substitution in circuit designs where the 2010 package footprint and 180 kOhms ±1% specification are required.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010180KFKEF or RMCF2010FT180K be used as direct replacements for RC5025F184CS?

A: Yes. Both substitute parts are electrically and mechanically compatible. They share identical resistance value (180 kOhms), tolerance (±1%), package (2010 / 5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute parts feature a higher power rating (0.75W vs. 0.667W), which represents improved thermal capability within the same package dimensions.

Q: What is the difference in physical dimensions between the main part and substitutes?

A: Length and width are identical at 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height differs slightly: RC5025F184CS is 0.026" (0.66mm), while CRCW2010180KFKEF and RMCF2010FT180K are 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Are the substitute parts suitable for automotive applications?

A: CRCW2010180KFKEF and RMCF2010FT180K both carry AEC-Q200 automotive qualification. RC5025F184CS does not list automotive certification. If automotive-grade components are required, CRCW2010180KFKEF or RMCF2010FT180K are the appropriate selections.

Q: What is the moisture sensitivity level for all three parts?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. RC5025F184CS, CRCW2010180KFKEF, and RMCF2010FT180K are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronics manufacturing.

Q: What is the temperature coefficient specification and does it differ between parts?

A: All three parts specify ±100ppm/°C temperature coefficient across the operating range of -55°C ~ 155°C. This parameter is identical and does not differentiate the parts.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes. The 2010 package footprint is standardized across all three parts. The maximum seated height variation (0.002") is negligible for standard PCB assembly processes. No design or layout changes are required for substitution.
