Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF4643U is determined by strict alignment of the following parameters:

• Resistance value: 464 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive certification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The CRCW2512464KFKEG from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF4643U and CRCW2512464KFKEG are active production components with identical electrical specifications and automotive certifications. Selection between these parts may be based on availability, supply chain considerations, or procurement preferences. Both components satisfy ROHS3 compliance and AEC-Q200 automotive qualification requirements. Physical dimensions show minor variations within the 2512 package specification, with both components maintaining identical height and termination count. Both parts carry MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512464KFKEG replace ERJ-S1TF4643U in automotive applications?

A: Yes. Both components carry AEC-Q200 certification, identical electrical specifications (464 kOhms ±1%, 1W, ±100ppm/°C), and operate across the same temperature range (-55°C ~ 155°C). Both are ROHS3 compliant and carry MSL 1 rating.

Q: Are there physical compatibility concerns between these parts?

A: Both components use the 2512 (6432 Metric) package with identical height (0.028" / 0.70mm maximum). Physical dimensions show minor variations (ERJ-S1TF4643U: 6.40mm x 3.20mm; CRCW2512464KFKEG: 6.30mm x 3.15mm), which remain within standard 2512 package tolerances and do not affect PCB layout compatibility.

Q: What determines substitution eligibility for this resistor?

A: Substitution requires matching resistance value (464 kOhms), tolerance (±1%), power rating (1W), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive certification (AEC-Q200).

Q: Are both parts suitable for high-reliability applications?

A: Both components meet AEC-Q200 automotive qualification standards and carry ROHS3 compliance. Both maintain MSL 1 rating, indicating no moisture sensitivity limitations.
