Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF4640U are qualified based on the following criteria:

• Identical resistance value: 464 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 1W
• Same package footprint: 2512 (6432 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Equivalent RoHS compliance: ROHS3 Compliant
• Equivalent moisture sensitivity: MSL 1 (Unlimited)

All identified substitutes meet these electrical and mechanical parameters, enabling direct replacement in automotive and industrial applications without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S1TF4640U, CRCW2512464RFKEG, and RMCF2512FT464R—are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection among these substitutes is determined by availability and supply chain requirements rather than electrical or mechanical performance differences.

The RMCF2512FT464R from Stackpole Electronics Inc currently has the highest inventory level at 8,652 units, followed by the ERJ-S1TF4640U at 1,090 units, and the CRCW2512464RFKEG at 885 units. Physical dimensions are within acceptable tolerances across all three parts for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512464RFKEG or RMCF2512FT464R be used as direct replacements for ERJ-S1TF4640U?

A: Yes. All three parts share identical electrical specifications (464 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C), the same 2512 package footprint, and equivalent automotive certifications. Physical dimension variations are within standard PCB assembly tolerances.

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

A: The ERJ-S1TF4640U explicitly includes anti-sulfur protection in its specification. The CRCW2512464RFKEG and RMCF2512FT464R specifications do not list this feature. For applications requiring anti-sulfur protection, verify with the manufacturer or retain the ERJ-S1TF4640U.

Q: Do all three parts meet automotive standards?

A: Yes. All parts carry AEC-Q200 qualification and ROHS3 compliance, suitable for automotive and industrial applications within the specified temperature range.

Q: What are the physical dimension differences?

A: The ERJ-S1TF4640U measures 0.252" L x 0.126" W (6.40mm x 3.20mm). The CRCW2512464RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). The RMCF2512FT464R measures 0.248" L x 0.126" W (6.30mm x 3.20mm). All maintain the same 0.028" (0.70mm) maximum seated height and are compatible with standard 2512 footprints.

Q: Which part should be selected for new designs?

A: Selection is based on supply availability and lead time. All three parts are functionally equivalent for this application. Verify anti-sulfur requirements with your design specifications before final selection.
