Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HRC1101X is determined by the following critical parameters:

• Resistance value: 1.1 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W) minimum
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Termination count: 2

The ERA-2ARC1101X qualifies as a direct substitute, meeting all electrical and mechanical specifications while offering extended operating temperature range (-55°C to 155°C) and automotive AEC-Q200 qualification. Both parts are manufactured by Panasonic Electronic Components and share identical resistance, tolerance, power rating, package configuration, and thin film composition.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC1101X is the qualified substitute for the obsolete ERA-2HRC1101X. Both components share identical electrical specifications (1.1 kOhms ±0.25%, 0.063W, ±10ppm/°C) and mechanical packaging (0402, 1.00mm x 0.50mm). The substitute maintains ROHS3 compliance and MSL 1 rating.

The ERA-2ARC1101X offers additional advantages: active product status ensures ongoing availability, extended operating temperature range to 155°C provides margin beyond the original -55°C to 125°C specification, and AEC-Q200 automotive qualification certifies reliability for demanding applications. These enhancements do not compromise compatibility with designs originally specified for the ERA-2HRC1101X.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC1101X directly replace ERA-2HRC1101X in existing designs?

A: Yes. Both parts are 1.1 kOhms ±0.25% thin film resistors in 0402 package with identical power ratings (0.063W), temperature coefficients (±10ppm/°C), and physical dimensions. Electrical and mechanical compatibility is complete.

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

A: The ERA-2A series incorporates AEC-Q200 automotive qualification and extends the operating temperature range to 155°C compared to the ERA-2H series maximum of 125°C. Both series use identical thin film technology and meet ROHS3 requirements.

Q: Does the extended temperature range of ERA-2ARC1101X affect circuit performance?

A: No. The extended range (-55°C to 155°C versus -55°C to 125°C) represents additional operational margin. The temperature coefficient remains ±10ppm/°C for both parts, ensuring equivalent frequency stability and thermal performance within the original design specification.

Q: Are there any package or footprint differences?

A: No. Both ERA-2HRC1101X and ERA-2ARC1101X use identical 0402 (1005 Metric) packaging 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: What is the moisture sensitivity level for the substitute part?

A: ERA-2ARC1101X carries MSL 1 (Unlimited), identical to the original ERA-2HRC1101X. No special moisture control measures are required during storage or handling.

Q: Is AEC-Q200 qualification required for my application?

A: AEC-Q200 qualification is mandatory for automotive applications. For non-automotive applications, the ERA-2ARC1101X remains fully compatible and offers the same electrical performance as the original part.
