ERA-2HEC3161P Equivalent & Substitute Parts

Part Overview

The ERA-2HEC3161P is a 3.16 kOhms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 1/16W (0.063W). Manufactured by Panasonic Electronic Components, this part operates across -55°C to 125°C with a temperature coefficient of ±25ppm/°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance applications requiring equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ERA-2HEC3161P is based on matching the following critical parameters:

• Resistance value: 3.16 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant

The ERA-2AEC3161X meets all these criteria and qualifies as a direct substitute. The ERA-2AEC series incorporates automotive AEC-Q200 qualification, extending the upper operating temperature to 155°C while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3161X is the direct substitute for the obsolete ERA-2HEC3161P. Both parts share identical electrical specifications (3.16 kOhms ±0.25%, 0.063W, ±25ppm/°C) and mechanical dimensions (0402 package). The ERA-2AEC3161X maintains active product status with full ROHS3 compliance and MSL 1 rating.

The primary distinction is the extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and AEC-Q200 automotive qualification of the ERA-2AEC3161X. For applications operating within the original -55°C to 125°C range, the ERA-2AEC3161X provides equivalent performance with the added benefit of automotive-grade reliability certification and extended temperature capability.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC3161X be used as a direct replacement for ERA-2HEC3161P?

A: Yes. Both parts have identical resistance (3.16 kOhms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC3161X is pin-compatible and footprint-compatible with no circuit modifications required.

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

A: The ERA-2AEC series incorporates AEC-Q200 automotive qualification and extends the upper operating temperature limit to 155°C, compared to 125°C for the ERA-2HEC series. All other electrical and mechanical parameters remain 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 (0.016", 0.40mm). PCB footprints are interchangeable.

Q: Does the ERA-2AEC3161X meet RoHS requirements?

A: Yes. The ERA-2AEC3161X is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the original ERA-2HEC3161P.

Q: Can I use ERA-2AEC3161X in applications limited to 125°C maximum temperature?

A: Yes. The ERA-2AEC3161X operates across -55°C to 155°C, which encompasses the original -55°C to 125°C range. It is suitable for all applications within the original temperature specification.
