Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F2492CS are identified based on the following critical parameters that determine functional interchangeability:

Electrical Matching Criteria:

• Resistance value: 24.9 kOhms (exact match required)
• Tolerance: ±1% (substitute must maintain or exceed precision)
• Temperature coefficient: ±100ppm/°C (thermal stability requirement)
• Operating temperature range: -55°C ~ 155°C (environmental compatibility)

Mechanical Compatibility Criteria:

• Package type: 2010 (5025 Metric) (physical footprint and PCB mounting compatibility)
• Number of terminations: 2 (standard two-terminal resistor configuration)
• Composition: Thick Film (material technology consistency)

Regulatory & Compliance Criteria:

• RoHS3 Compliance (mandatory for regulated applications)
• Moisture Sensitivity Level: MSL 1 (handling compatibility)

Power Rating Consideration: Substitutes with equal or higher power ratings (0.667W or greater) are acceptable, as thermal capability above the minimum requirement does not compromise circuit function and provides design margin.

The CRCW201024K9FKEF from Vishay Dale meets all critical substitution criteria with identical electrical specifications, identical package dimensions, and enhanced power rating (0.75W), making it a direct functional equivalent.

Engineering Selection Recommendations

Primary Substitute: CRCW201024K9FKEF (Vishay Dale)

The CRCW201024K9FKEF is a direct functional equivalent to the RC5025F2492CS. Selection of this substitute is based on the following engineering factors:

1. Electrical Specification Alignment: Identical resistance value (24.9 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) ensure equivalent circuit performance.

2. Mechanical Compatibility: Identical 2010 (5025 Metric) package footprint and dimensions (5.00mm x 2.50mm) provide direct PCB layout compatibility. Maximum seated height difference (0.028" vs 0.026") is within standard assembly tolerances.

3. Thermal Margin: The substitute's 0.75W power rating exceeds the original 0.667W requirement, providing additional thermal design margin without affecting circuit function.

4. Regulatory Compliance: Both components maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent handling, storage, and environmental performance.

5. Product Availability: Both components maintain Active product status with established supply chains.

6. Automotive Qualification: The CRCW201024K9FKEF carries AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can the CRCW201024K9FKEF replace the RC5025F2492CS in any application?

A: Yes. The substitute meets all critical electrical, mechanical, and regulatory parameters. The higher power rating (0.75W vs 0.667W) provides additional thermal capability without compromising circuit function. Both components operate across the identical temperature range (-55°C ~ 155°C) with matching tolerance and temperature coefficient specifications.

Q: Are there any height or footprint differences that affect PCB assembly?

A: The maximum seated heights differ by 0.002" (0.04mm): RC5025F2492CS at 0.026" (0.66mm) and CRCW201024K9FKEF at 0.028" (0.70mm). This difference is within standard PCB assembly tolerances and does not affect component placement or soldering processes. Both components use identical 2010 (5025 Metric) package footprints (5.00mm x 2.50mm).

Q: Do both components have the same moisture sensitivity requirements?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Handling, storage, and reflow processes are identical for both parts.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive industry qualification standard. The CRCW201024K9FKEF's AEC-Q200 rating indicates enhanced reliability testing and documentation. This qualification is beneficial for applications requiring automotive-grade components but does not affect compatibility with non-automotive applications.

Q: Are the tolerance and temperature coefficient specifications identical?

A: Yes. Both components specify ±1% tolerance and ±100ppm/°C temperature coefficient, ensuring equivalent precision and thermal stability across the operating temperature range.

Q: Can the substitute be used in high-temperature applications near 155°C?

A: Yes. Both components are rated for continuous operation up to 155°C. The substitute's higher power rating (0.75W) provides additional thermal margin in high-temperature environments.

Q: Is there any difference in RoHS compliance between the two parts?

A: No. Both components are ROHS3 compliant, meeting identical regulatory requirements for hazardous substance restrictions.
