Frequently Asked Questions (FAQ)

Q: Can CRCW25124K75FKEG replace ERJ-S1TF4751U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across the same temperature range (-55°C ~ 155°C), and share identical electrical specifications (4.75 kOhms ±1%, 1W, ±100ppm/°C). Both are ROHS3 compliant with MSL 1 rating.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. ERJ-S1TF4751U is 6.40mm x 3.20mm; CRCW25124K75FKEG is 6.30mm x 3.15mm. Both fit the 2512 (6432 Metric) package specification and share identical maximum seated height (0.70mm). These variations are within standard PCB layout tolerances.

Q: What determines substitution eligibility for 2512 chip resistors?

A: Substitution requires matching resistance value, tolerance, power rating, package type, composition, temperature coefficient, operating temperature range, and automotive/compliance certifications. All these parameters must be identical between the primary and substitute part.

Q: Are both parts suitable for high-temperature automotive environments?

A: Yes. Both parts are rated for -55°C ~ 155°C operation and carry AEC-Q200 qualification, confirming suitability for automotive thermal cycling and environmental stress conditions.

Q: What is the significance of the anti-sulfur feature on the ERJ-S1TF4751U?

A: The anti-sulfur coating on the ERJ-S1TF4751U provides enhanced corrosion resistance in harsh environments. The CRCW25124K75FKEG does not list this specific feature in the provided specifications.
