ERA-2HEC2741P Equivalent & Substitute Parts

Part Overview

The ERA-2HEC2741P is a 2.74 kOhms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 1/16W (0.063W). This component is manufactured by Panasonic Electronic Components and is currently classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure supply chain availability for new production runs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HEC2741P is determined by the following critical parameters:

• Resistance Value: 2.74 kOhms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power Rating: 0.063W, 1/16W (electrical stress rating)
• Package Type: 0402 (1005 Metric) (physical and footprint compatibility)
• Composition: Thin Film (performance and stability characteristics)
• Temperature Coefficient: ±25ppm/°C (thermal stability)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The ERA-2AEC2741X qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the addition of AEC-Q200 automotive qualification and an extended upper operating temperature limit.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC2741X is a direct functional substitute for the ERA-2HEC2741P. Both components share identical electrical specifications (resistance, tolerance, power rating, temperature coefficient) and physical package dimensions. The ERA-2AEC2741X is currently in active production status, addressing the supply constraint created by the obsolescence of the ERA-2HEC2741P.

The ERA-2AEC2741X provides additional benefits through AEC-Q200 automotive qualification and an extended upper operating temperature limit of 155°C compared to 125°C. These enhancements do not introduce incompatibility; they represent a superset of the original part's capabilities. Both components maintain ROHS3 compliance and MSL 1 rating.

Selection of the ERA-2AEC2741X is appropriate for applications where the original ERA-2HEC2741P is no longer available, provided the design does not explicitly exclude automotive-qualified components.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC2741X be used as a direct replacement for ERA-2HEC2741P in existing designs?

A: Yes. Both parts share identical resistance (2.74 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC2741X is electrically and mechanically compatible with designs specified for the ERA-2HEC2741P.

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

A: The ERA-2A series includes AEC-Q200 automotive qualification and operates to 155°C maximum, compared to the ERA-2H series which operates to 125°C maximum. Both series use identical thin film technology and precision tolerance specifications.

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

A: No. Both components 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 and assembly processes are interchangeable.

Q: Does the AEC-Q200 qualification on the ERA-2AEC2741X affect non-automotive applications?

A: No. AEC-Q200 qualification represents additional testing and quality assurance. It does not restrict use in non-automotive applications and does not introduce any incompatibility with existing designs.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERA-2HEC2741P and ERA-2AEC2741X are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.
