Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC1802X is the appropriate substitute for the obsolete ERA-2HRC1802P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical and mechanical specifications. The substitute part maintains ROHS3 compliance and unlimited MSL rating, ensuring compatibility with standard PCB assembly processes.

The ERA-2ARC1802X carries active product status, ensuring long-term availability and supply chain continuity. The extended operating temperature range (-55°C ~ 155°C) and automotive AEC-Q200 qualification provide additional performance margin for applications requiring enhanced reliability. Pin-to-pin and footprint compatibility is guaranteed, enabling direct substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC1802X be used as a direct replacement for ERA-2HRC1802P?

A: Yes. Both parts share identical resistance (18 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), temperature coefficient (±10ppm/°C), physical dimensions, and termination count. Footprint and electrical performance are fully compatible.

Q: What is the difference between these two parts?

A: The ERA-2ARC1802X operates across an extended temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and includes automotive AEC-Q200 qualification. The ERA-2HRC1802P is obsolete, while the ERA-2ARC1802X maintains active product status.

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 layout modifications are not required.

Q: Do both parts meet RoHS requirements?

A: Yes. Both ERA-2HRC1802P and ERA-2ARC1802X are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: Is the substitute part suitable for automotive applications?

A: The ERA-2ARC1802X carries automotive AEC-Q200 qualification, making it suitable for automotive-grade applications. The ERA-2HRC1802P does not include this certification.
