Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F1471CS are qualified based on the following criteria:

Electrical Equivalence Requirements:

• Identical resistance value: 1.47 kOhms
• Matching tolerance: ±1%
• Equal or higher power rating: minimum 0.667W (2/3W)
• Identical temperature coefficient: ±100ppm/°C
• Matching operating temperature range: -55°C to 155°C

Mechanical Compatibility Requirements:

• Identical package designation: 2010 (5025 Metric)
• Identical composition: Thick Film
• Two terminations (standard for chip resistors)
• Physical dimensions compatible with 2010 footprint

Compliance Requirements:

• RoHS3 compliance maintained
• MSL rating of 1 or equivalent
• Active product status

The CRCW20101K47FKEF from Vishay Dale meets all electrical and mechanical criteria while providing enhanced power rating (0.75W vs. 0.667W) and automotive-grade qualification (AEC-Q200), making it a direct substitute with superior performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F1471CS): Select the Samsung Electro-Mechanics RC5025F1471CS when the original specification is required and inventory is available. This component maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute Selection (CRCW20101K47FKEF): The Vishay Dale CRCW20101K47FKEF is a qualified substitute when the RC5025F1471CS is unavailable. This part provides identical electrical performance with enhanced power rating (0.75W vs. 0.667W) and automotive-grade AEC-Q200 qualification. The marginal height difference (0.028" vs. 0.026") remains within standard PCB assembly tolerances for 2010 package footprints. Both components maintain identical RoHS3 compliance and MSL 1 ratings, ensuring equivalent environmental performance in production and field applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW20101K47FKEF replace RC5025F1471CS in all applications?

A: Yes. The CRCW20101K47FKEF meets all electrical and mechanical requirements for direct substitution. The higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance. Both components share identical resistance value, tolerance, temperature coefficient, operating range, and package footprint.

Q: What is the significance of the power rating difference?

A: The CRCW20101K47FKEF is rated for 0.75W compared to the RC5025F1471CS at 0.667W. This 12.5% higher rating provides additional thermal headroom in power dissipation scenarios. For applications operating at or below 0.667W, both parts perform identically. For applications approaching the 0.667W limit, the substitute offers improved reliability margin.

Q: Are there packaging differences between these parts?

A: Both components use the 2010 (5025 Metric) package with identical footprint dimensions (5.00mm x 2.50mm). The seated height differs marginally (0.028" vs. 0.026"), which is within standard PCB assembly tolerances and does not affect board-level compatibility or reflow processing.

Q: Does the AEC-Q200 rating on the substitute affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates enhanced reliability testing and quality assurance. This certification does not alter electrical or mechanical performance and is fully compatible with non-automotive applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC5025F1471CS and CRCW20101K47FKEF maintain full RoHS3 compliance with identical MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental performance and regulatory compliance.

Q: What is the temperature coefficient significance?

A: Both parts share an identical temperature coefficient of ±100ppm/°C across the -55°C to 155°C operating range. This ensures predictable resistance drift with temperature variations and maintains circuit stability across the full environmental envelope.
