Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF4642U is determined by strict alignment of the following parameters:

• Resistance value: 46.4 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 level: 1 (Unlimited)

The CRCW251246K4FKEG from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF4642U and CRCW251246K4FKEG are active production components with identical electrical specifications and automotive certifications. Selection between these parts should be based on availability, supply chain requirements, and procurement preferences. Both components carry ROHS3 compliance and AEC-Q200 automotive qualification, making them suitable for equivalent circuit applications. Physical dimensions show minor variations within the 2512 package specification, with both components maintaining the same maximum seated height of 0.028" (0.70mm).

Frequently Asked Questions (FAQ)

Q: Can CRCW251246K4FKEG be used as a direct replacement for ERJ-S1TF4642U?

A: Yes. Both components share identical electrical specifications (46.4 kOhms ±1%, 1W), composition (thick film), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), package type (2512), and automotive certifications (AEC-Q200). Physical dimensions are within acceptable tolerance for the 2512 package footprint.

Q: Are there any compliance differences between these parts?

A: No. Both components are ROHS3 compliant, carry AEC-Q200 automotive qualification, have moisture sensitivity level 1 (unlimited), and share identical REACH and ECCN classifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching resistance value (46.4 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: Do the minor physical dimension differences affect PCB layout?

A: No. Both components conform to the 2512 (6432 Metric) package specification. The dimensional variations (0.252" vs 0.248" length, 0.126" vs 0.124" width) are within standard package tolerances and do not affect footprint compatibility or assembly processes.

Q: What is the inventory status for these parts?

A: ERJ-S1TF4642U has 910 units in stock. CRCW251246K4FKEG has 6225 units in stock.
