Key Parameters

Substitute Part Grouping Explanation

Substitution between ERA-2HRC9100X and ERA-2ARC9100X is permissible based on the following matched electrical and mechanical parameters:

• Resistance value: 910 Ohms (identical)
• Tolerance: ±0.25% (identical)
• Power rating: 0.063W, 1/16W (identical)
• Package: 0402 (1005 Metric) (identical)
• Composition: Thin Film (identical)
• Temperature coefficient: ±10ppm/°C (identical)
• Physical dimensions: 0.039" L x 0.020" W, 0.016" max height (identical)
• Terminations: 2 (identical)
• RoHS compliance: ROHS3 (identical)
• MSL rating: 1 (Unlimited) (identical)

The ERA-2ARC9100X extends the upper operating temperature limit to 155°C and includes AEC-Q200 automotive qualification, making it suitable for applications requiring enhanced temperature performance or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC9100X is the appropriate substitute for the obsolete ERA-2HRC9100X. Both components share identical electrical specifications (910 Ohms ±0.25%, 0.063W) and mechanical form factor (0402 package). The ERA-2ARC9100X maintains active product status with current manufacturing availability, eliminating supply chain risk associated with the obsolete ERA-2HRC9100X.

For applications operating within the -55°C to 125°C range, either part satisfies the thermal requirement. For applications requiring operation up to 155°C, the ERA-2ARC9100X provides the extended temperature capability. The AEC-Q200 automotive qualification of the ERA-2ARC9100X does not restrict its use in non-automotive applications and represents an additional quality assurance level.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC9100X replace ERA-2HRC9100X in all applications?

A: Yes, provided the application does not require the specific series designation of the ERA-2H line. The ERA-2ARC9100X matches all critical electrical and mechanical parameters: 910 Ohm resistance, ±0.25% tolerance, 0.063W power rating, 0402 package, and ±10ppm/°C temperature coefficient.

Q: What is the difference between ERA-2HRC9100X and ERA-2ARC9100X?

A: The ERA-2ARC9100X extends the maximum operating temperature from 125°C to 155°C and includes AEC-Q200 automotive qualification. The ERA-2HRC9100X is obsolete; the ERA-2ARC9100X is in active production.

Q: Are the physical dimensions identical?

A: Yes. Both components are 0402 (1005 Metric) package with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints are interchangeable.

Q: Does AEC-Q200 qualification affect non-automotive use?

A: No. AEC-Q200 qualification indicates enhanced reliability testing and quality standards. Components with automotive qualification are suitable for general industrial and commercial applications without restriction.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HRC9100X and ERA-2ARC9100X are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).
