Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HRC1800P is determined by strict equivalence across the following parameters:

• Resistance value: 180 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• Composition: Thin Film (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

The ERA-2ARC1800X meets all substitution criteria. This part maintains identical electrical specifications and physical dimensions while offering an extended operating temperature range and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC1800X is a direct functional substitute for the obsolete ERA-2HRC1800P. Both components share identical electrical and mechanical specifications, ensuring drop-in compatibility in existing circuit designs.

The ERA-2ARC1800X offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin
• AEC-Q200 automotive qualification enables use in automotive and high-reliability applications
• ROHS3 compliance maintained across both parts
• Identical package footprint (0402) and termination count (2) for PCB layout compatibility

Selection between these parts depends on application requirements. For applications requiring automotive qualification or extended temperature operation, the ERA-2ARC1800X is the appropriate choice. For general-purpose applications where the original operating temperature range is sufficient, the ERA-2ARC1800X remains compatible and offers the advantage of active product status.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC1800X replace ERA-2HRC1800P in existing designs?

A: Yes. The ERA-2ARC1800X is electrically and mechanically equivalent. Resistance, tolerance, power rating, composition, package, temperature coefficient, and moisture sensitivity are identical. PCB layout and circuit design require no modification.

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

A: The ERA-2A series includes automotive-grade qualification (AEC-Q200) and extended operating temperature range. The ERA-2H series is the standard industrial grade. Both series use identical thin film technology and meet ROHS3 compliance.

Q: Are there any thermal performance differences?

A: Both parts have identical power ratings (0.063W) and thermal characteristics at their respective operating temperature limits. The ERA-2ARC1800X extends the upper operating temperature to 155°C compared to 125°C for the ERA-2HRC1800P.

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

A: Yes. 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 of 0.016" (0.40mm).

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HRC1800P and ERA-2ARC1800X are ROHS3 compliant.
