Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC71R5P is determined by strict equivalence across the following parameters:

• Resistance value: 71.5 Ohms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2AEC71R5X meets all these criteria and is manufactured by the same supplier, Panasonic Electronic Components. This part is functionally equivalent with enhanced operating temperature range and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC71R5X is the direct substitute for the obsolete ERA-2HEC71R5P. Both parts share identical electrical specifications, package dimensions, and environmental ratings. The ERA-2AEC71R5X offers the advantage of active product status with extended operating temperature capability to 155°C and AEC-Q200 automotive qualification. For applications requiring automotive-grade components or extended temperature performance, the ERA-2AEC71R5X is the appropriate selection. For standard industrial applications within the -55°C to 125°C range, both parts are electrically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC71R5X replace ERA-2HEC71R5P in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 71.5 Ohms ±0.25%, 0.063W power rating, 0402 package, thin film composition, and ±25ppm/°C temperature coefficient. The ERA-2AEC71R5X is a direct substitute with extended temperature range and automotive qualification.

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

A: The ERA-2A series includes AEC-Q200 automotive qualification and extended operating temperature to 155°C. The ERA-2H series is the standard industrial version. Electrical performance and package specifications are identical.

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-2AEC71R5X suitable for high-temperature applications?

A: The ERA-2AEC71R5X operates to 155°C maximum, compared to 125°C for the ERA-2HEC71R5P. For applications requiring operation above 125°C, the ERA-2AEC71R5X provides additional thermal margin.

Q: What is the inventory status for these parts?

A: ERA-2HEC71R5P: 1027 Pcs (Obsolete status). ERA-2AEC71R5X: 1051 Pcs (Active product). For new designs and long-term availability, the ERA-2AEC71R5X is recommended.
