Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF4641U are qualified based on the following critical parameters:

• Resistance value: 4.64 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The CRCW25124K64FKEG from Vishay Dale meets all critical electrical and mechanical parameters, differing only in minor dimensional tolerances within acceptable manufacturing ranges for the 2512 package footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF4641U and CRCW25124K64FKEG are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

• Supply availability and lead time requirements
• Procurement cost and volume pricing
• Existing qualification documentation for your specific application
• PCB layout constraints, as dimensional variations between manufacturers are within standard 2512 package tolerances

The dimensional differences (length and width) are within normal manufacturing tolerances for the 2512 package and do not affect PCB footprint compatibility or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW25124K64FKEG be used as a direct replacement for ERJ-S1TF4641U?

A: Yes. Both parts share identical electrical specifications (4.64 kOhms, ±1%, 1W), identical package designation (2512), identical temperature coefficient (±100ppm/°C), identical operating range (-55°C ~ 155°C), and identical automotive qualification (AEC-Q200). Dimensional variations are within standard 2512 package tolerances.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under the same HTSUS code (8533.21.0030). Both carry MSL rating of 1 (Unlimited).

Q: What is the significance of the anti-sulfur feature on the ERJ-S1TF4641U?

A: The anti-sulfur coating on the Panasonic part provides additional protection in high-sulfur environments. The Vishay Dale substitute does not list this feature in the provided specifications. If anti-sulfur protection is a design requirement, the ERJ-S1TF4641U should be specified.

Q: Are these parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification, which certifies them for automotive-grade reliability and performance standards.

Q: What is the difference in package dimensions?

A: The ERJ-S1TF4641U measures 0.252" L × 0.126" W (6.40mm × 3.20mm), while the CRCW25124K64FKEG measures 0.248" L × 0.124" W (6.30mm × 3.15mm). Both fit the standard 2512 (6432 Metric) footprint. These variations are within normal manufacturing tolerances and do not affect PCB layout compatibility.
