Parameter Comparison

Engineering Selection Recommendations

All three components—ERJ-S14F4702U, CRCW121047K0FKEA, and RC1210FR-0747KL—are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on availability, supply chain considerations, and specific application requirements.

The ERJ-S14F4702U includes AEC-Q200 automotive qualification and anti-sulfur features. The CRCW121047K0FKEA also carries AEC-Q200 qualification. The RC1210FR-0747KL features moisture-resistant construction without explicit AEC-Q200 designation.

For automotive applications requiring AEC-Q200 certification, either the ERJ-S14F4702U or CRCW121047K0FKEA is appropriate. For general industrial applications, all three parts are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can CRCW121047K0FKEA directly replace ERJ-S14F4702U?

A: Yes. Both components share identical electrical specifications (47 kOhms ±1%, 0.5W), operate across -55°C to 155°C, and meet ROHS3 compliance. Both carry AEC-Q200 automotive qualification. The primary difference is seated height: ERJ-S14F4702U measures 0.028" (0.70mm) while CRCW121047K0FKEA measures 0.024" (0.60mm). Verify PCB layout clearance before substitution.

Q: Is RC1210FR-0747KL suitable for automotive applications?

A: RC1210FR-0747KL meets all electrical and mechanical specifications equivalent to ERJ-S14F4702U and carries ROHS3 compliance. However, it does not list AEC-Q200 qualification. Use this part only in non-automotive applications or where AEC-Q200 is not a design requirement.

Q: What determines substitution compatibility?

A: Substitution compatibility is determined by matching resistance value, tolerance, power rating, package type, composition, temperature coefficient, operating temperature range, and compliance certifications. All three parts listed meet these criteria for general substitution purposes.

Q: Are there dimensional concerns when substituting?

A: The seated height varies slightly between parts. ERJ-S14F4702U has maximum seated height of 0.028" (0.70mm), while CRCW121047K0FKEA and RC1210FR-0747KL both measure 0.024" (0.60mm) maximum. Verify PCB design clearances and component placement constraints before substitution.

Q: Do all substitute parts have unlimited moisture sensitivity?

A: Yes. All three components carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling or storage requirements during assembly and deployment.
