Parameter Comparison

Engineering Selection Recommendations

All three components—ERJ-S1TF3013U, CRCW2512301KFKEG, and RMCF2512FT301K—are active production parts with full AEC-Q200 automotive certification and ROHS3 compliance. Selection among these equivalents may be based on availability, supply chain considerations, or procurement preferences, as all meet identical electrical and mechanical specifications. The RMCF2512FT301K offers the highest inventory availability at 9048 units, followed by CRCW2512301KFKEG at 4653 units, while ERJ-S1TF3013U maintains 877 units in stock.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512301KFKEG replace ERJ-S1TF3013U directly?

A: Yes. Both components share identical resistance, tolerance, power rating, package, temperature coefficient, operating temperature range, and AEC-Q200 certification. Physical dimensions are within acceptable tolerance for PCB footprints designed for the 2512 package.

Q: Are there differences in the physical dimensions between these parts?

A: Minor dimensional variations exist. ERJ-S1TF3013U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while CRCW2512301KFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm), and RMCF2512FT301K measures 0.248" L x 0.126" W (6.30mm x 3.20mm). All three maintain the same maximum seated height of 0.028" (0.70mm) and are compatible with standard 2512 PCB footprints.

Q: Do all substitutes meet automotive requirements?

A: Yes. All three parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and identical moisture sensitivity levels, making them suitable for automotive and industrial applications.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: This parameter defines the resistor's stability across the operating temperature range of -55°C to 155°C. All three parts share this specification, ensuring consistent performance in thermal cycling environments.

Q: Are there any anti-sulfur or special feature differences?

A: The ERJ-S1TF3013U is specifically noted as anti-sulfur construction. The CRCW2512301KFKEG and RMCF2512FT301K specifications do not explicitly list anti-sulfur features, though both maintain AEC-Q200 automotive qualification.
