Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC1180P is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 118 Ohms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Package: 0402 (1005 Metric)
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2AEC1180X meets all these criteria and is identified as a direct substitute. The primary distinction is product status and operating temperature range extension, with the substitute offering active availability and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1180X is the direct equivalent for ERA-2HEC1180P replacement. Both parts share identical electrical specifications, package geometry, and environmental ratings. The substitute 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 operation, the ERA-2AEC1180X provides enhanced compliance and availability. For standard industrial applications within the -55°C to 125°C range, both parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC1180X be used as a direct replacement for ERA-2HEC1180P?

A: Yes. Both parts are 118 Ohms ±0.25% thin film resistors in 0402 package with identical power ratings, temperature coefficients, and environmental specifications. They are electrically and mechanically interchangeable.

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

A: The ERA-2AEC series includes AEC-Q200 automotive qualification and extends the maximum operating temperature to 155°C, compared to 125°C for the ERA-2HEC series. Both maintain the same electrical characteristics and package specifications.

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).

Q: Is the ERA-2AEC1180X suitable for automotive applications?

A: Yes. The ERA-2AEC1180X carries AEC-Q200 qualification, making it suitable for automotive-grade applications. The ERA-2HEC1180P does not have automotive qualification.

Q: What is the tolerance specification for both parts?

A: Both parts maintain ±0.25% tolerance on the 118 Ohm resistance value, meeting precision thin film resistor specifications.
