ERA-2HEC47R5X Equivalent & Substitute Parts

Part Overview

The ERA-2HEC47R5X is a 47.5 Ohm ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W). Manufactured by Panasonic Electronic Components, this component is classified as obsolete. Finding equivalent and substitute parts is necessary due to the discontinued status of the ERA-2H series, ensuring continued availability for maintenance, repair, and new design implementations where this specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC47R5X is determined by the following critical parameters:

• Resistance Value: 47.5 Ohms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power Rating: 0.063W, 1/16W (electrical stress limit)
• Package: 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-2AEC47R5X qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering an active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC47R5X is the qualified substitute for the obsolete ERA-2HEC47R5X. Both components share identical electrical specifications (47.5 Ohms, ±0.25% tolerance, 0.063W power rating) and physical packaging (0402 1005 Metric). The substitute maintains the same temperature coefficient (±25ppm/°C) and RoHS3 compliance status.

The ERA-2AEC47R5X offers two distinct advantages: active product status ensuring long-term availability, and extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C). The substitute carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

Selection of the ERA-2AEC47R5X is appropriate for all applications where the ERA-2HEC47R5X was originally specified, with the extended temperature range providing additional operational margin in high-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC47R5X be used as a direct replacement for the ERA-2HEC47R5X?

A: Yes. Both components have identical resistance (47.5 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The substitute is electrically and mechanically compatible.

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

A: The ERA-2A series includes AEC-Q200 automotive qualification and extends the operating temperature range to 155°C, compared to 125°C for the ERA-2H series. Both series use identical thin film composition and maintain the same precision tolerance.

Q: Does the extended temperature range of the ERA-2AEC47R5X affect compatibility?

A: No. The extended range (-55°C ~ 155°C) is a superset of the original specification (-55°C ~ 125°C). The substitute operates safely within the original temperature limits and provides additional margin for higher-temperature applications.

Q: Are there any RoHS or compliance differences?

A: Both components are ROHS3 compliant with MSL 1 (Unlimited). The ERA-2AEC47R5X adds AEC-Q200 automotive certification, which does not restrict use in non-automotive applications.

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

A: Yes. 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 (0.016", 0.40mm). PCB footprints are interchangeable.
