Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC4020P is determined by strict equivalence across the following critical parameters:

• Resistance value: 402 Ohms
• 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-2AEC4020X qualifies as a direct substitute based on matching all electrical specifications and package dimensions. The primary distinction is product status and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC4020X serves as the direct substitute for the obsolete ERA-2HEC4020P. Both components share identical electrical specifications, package dimensions, and RoHS3 compliance status. The ERA-2AEC4020X is currently in active production status, ensuring long-term availability and supply chain continuity.

The ERA-2AEC4020X incorporates AEC-Q200 automotive qualification and extends the operating temperature range to -55°C ~ 155°C, providing enhanced thermal performance compared to the original part's -55°C ~ 125°C range. This extended temperature capability presents no compatibility concerns for applications originally designed for the ERA-2HEC4020P, as the substitute maintains all baseline electrical and mechanical parameters.

Selection of the ERA-2AEC4020X is appropriate for new designs, production restarts, and component replenishment where the ERA-2HEC4020P is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC4020X be used as a direct replacement for ERA-2HEC4020P in existing designs?

A: Yes. Both components share identical resistance (402 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC4020X is electrically and mechanically compatible with designs originally specified for the ERA-2HEC4020P.

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

A: The ERA-2A series incorporates AEC-Q200 automotive qualification and operates across an extended temperature range (-55°C ~ 155°C) compared to the ERA-2H series (-55°C ~ 125°C). Both series maintain identical thin film composition and tolerance specifications.

Q: Are there any package or footprint differences between these parts?

A: No. Both the ERA-2HEC4020P and ERA-2AEC4020X 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 (0.016" / 0.40mm). PCB footprints are interchangeable.

Q: Is the ERA-2AEC4020X RoHS compliant?

A: Yes. The ERA-2AEC4020X is ROHS3 compliant, matching the compliance status of the ERA-2HEC4020P.

Q: What is the moisture sensitivity level for these components?

A: Both components have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life under normal storage conditions.
