Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HRC1800X is determined by the following critical parameters:

• Resistance value: 180 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Package: 0402 (1005 Metric) (exact match required for PCB compatibility)
• Composition: Thin Film (maintains electrical performance characteristics)
• Temperature coefficient: ±10ppm/°C (exact match required for stability)
• RoHS compliance: ROHS3 minimum (regulatory requirement)

The ERA-2ARC1800X meets all substitution criteria as an active product with identical electrical specifications and enhanced operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC1800X is the direct functional equivalent for ERA-2HRC1800X applications. Both components share identical electrical specifications, physical dimensions, and regulatory compliance. The ERA-2ARC1800X offers the advantage of active product status with extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and automotive AEC-Q200 qualification. For applications requiring standard industrial-grade components, the ERA-2ARC1800X provides superior long-term availability and supply chain continuity. The automotive qualification does not restrict use in non-automotive applications and represents an enhancement in component reliability and testing rigor.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC1800X directly replace ERA-2HRC1800X in existing designs?

A: Yes. Both components are 180 Ohm ±0.25% thin film resistors in 0402 package with identical electrical performance, physical dimensions, and thermal characteristics. No circuit redesign or PCB modification is required.

Q: What is the significance of the AEC-Q200 automotive qualification on the ERA-2ARC1800X?

A: AEC-Q200 certification indicates the component meets automotive industry reliability and testing standards. This qualification does not restrict the part to automotive applications and reflects enhanced manufacturing controls and quality assurance applicable to all end-use categories.

Q: Are there any temperature range limitations when substituting ERA-2ARC1800X for ERA-2HRC1800X?

A: No. The ERA-2ARC1800X operates across -55°C to 155°C, which encompasses the original -55°C to 125°C range. Applications operating within the original temperature window experience no functional change.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both ERA-2HRC1800X and ERA-2ARC1800X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory standards.

Q: Is the 0402 package dimension identical between both parts?

A: Yes. Both components measure 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm), ensuring mechanical and electrical compatibility on existing PCBs without layout modifications.
