Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC1802P is determined by strict equivalence across the following parameters:

• Resistance value: 18 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2AEC1802X meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and operating temperature range extension, which does not restrict substitution in applications designed for the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1802X is a direct functional equivalent to the ERA-2HEC1802P. Both parts share identical electrical specifications, package geometry, and composition. The ERA-2AEC1802X carries active product status and includes AEC-Q200 automotive qualification, providing enhanced supply chain availability and extended operating temperature range to 155°C. Selection of the ERA-2AEC1802X is appropriate for applications previously designed with the ERA-2HEC1802P, with the additional benefit of automotive-grade reliability certification and broader temperature performance margin.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC1802X replace the ERA-2HEC1802P in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 18 kOhms resistance, ±0.25% tolerance, 0.063W power rating, 0402 package, thin film composition, and ±25ppm/°C temperature coefficient. The ERA-2AEC1802X operates across -55°C to 155°C, which encompasses the original part's -55°C to 125°C range.

Q: What is the difference between ERA-2HEC and ERA-2AEC series?

A: The ERA-2AEC series includes AEC-Q200 automotive qualification and active product status, while the ERA-2HEC series is classified as obsolete. Both series share identical electrical and mechanical specifications for equivalent part numbers.

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 of 0.016" (0.40mm). PCB footprints are interchangeable.

Q: Is the ERA-2AEC1802X RoHS compliant?

A: Yes. The ERA-2AEC1802X is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.
