Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S1DF4643U is determined by strict equivalence across the following parameters:

• Resistance value: 464 kOhms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The CRCW2010464KFKEF manufactured by Vishay Dale meets all these criteria and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can CRCW2010464KFKEF be used as a direct replacement for ERJ-S1DF4643U?

A: Yes. Both parts share identical electrical specifications (464 kOhms ±1%, 0.75W), mechanical dimensions (2010 package), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and automotive qualification (AEC-Q200). No circuit modifications are required.

Q: Are there differences in the anti-sulfur coating between these parts?

A: The ERJ-S1DF4643U is specified with anti-sulfur coating. The CRCW2010464KFKEF specification provided does not explicitly list anti-sulfur coating. This difference should be evaluated based on application requirements in corrosive environments.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the tape and reel packaging specifications identical?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging with identical physical dimensions and termination count (2 terminations).

Q: What is the REACH and RoHS compliance status for both parts?

A: Both components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.
