Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC73R2X be used as a direct replacement for the ERA-2HEC73R2P?

A: Yes. Both parts are identical in resistance value (73.2 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). The ERA-2AEC73R2X is a direct substitute with no circuit modifications required.

Q: What is the difference between the ERA-2H and ERA-2A series?

A: The ERA-2A series includes AEC-Q200 automotive qualification and an extended operating temperature range to 155°C, compared to the ERA-2H series maximum of 125°C. Electrical specifications remain identical.

Q: Are there any package or footprint differences?

A: No. Both parts use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.016", 0.40mm). PCB footprints are interchangeable.

Q: Does the ERA-2AEC73R2X meet RoHS and MSL requirements?

A: Yes. The ERA-2AEC73R2X is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), matching the compliance profile of the ERA-2HEC73R2P.

Q: Why is the ERA-2HEC73R2P obsolete?

A: Product obsolescence is determined by the manufacturer. The ERA-2AEC73R2X provides equivalent functionality with active product status and enhanced specifications, making it the recommended alternative for ongoing designs and production.
