ERA-2HEC1371P Equivalent & Substitute Parts

Part Overview

The ERA-2HEC1371P is a 1.37 kOhms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W). Manufactured by Panasonic Electronic Components, this part operates across -55°C to 125°C with a temperature coefficient of ±25ppm/°C and is ROHS3 compliant with MSL 1 rating.

The ERA-2HEC1371P is currently obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this specific resistance value and tolerance class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC1371P is determined by the following critical parameters:

• Resistance Value: Must be 1.37 kOhms
• Tolerance: Must be ±0.25% or tighter
• Power Rating: Must be 0.063W (1/16W) or higher
• Package: Must be 0402 (1005 Metric)
• Composition: Must be thin film
• Temperature Coefficient: Must be ±25ppm/°C or better
• Operating Temperature Range: Must cover at least -55°C ~ 125°C
• RoHS Compliance: Must be ROHS3 compliant

The ERA-2AEC1371X meets all substitution criteria and is classified as a direct equivalent with enhanced automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1371X is the direct substitute for the obsolete ERA-2HEC1371P. Both parts share identical electrical specifications: 1.37 kOhms resistance, ±0.25% tolerance, 0.063W power rating, and ±25ppm/°C temperature coefficient in the same 0402 package.

The ERA-2AEC1371X offers two advantages over the main part:

• Active Product Status: Currently in production and available in inventory (1094 Pcs), ensuring long-term supply availability
• Extended Operating Temperature Range: Rated to 155°C versus 125°C, providing additional thermal margin
• Automotive AEC-Q200 Qualification: Meets automotive reliability standards, suitable for automotive and high-reliability applications

Both parts are ROHS3 compliant with MSL 1 rating and identical physical dimensions. The ERA-2AEC1371X is suitable for direct replacement in all applications where the ERA-2HEC1371P was specified.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC1371X replace the ERA-2HEC1371P in all applications?

A: Yes. The ERA-2AEC1371X meets or exceeds all electrical and mechanical specifications of the ERA-2HEC1371P. The extended operating temperature range (-55°C ~ 155°C) and automotive qualification provide additional capability without compromising compatibility.

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

A: The ERA-2A series includes AEC-Q200 automotive qualification and an extended upper operating temperature limit of 155°C compared to 125°C for the ERA-2H series. Both series use identical thin film composition and tolerance specifications.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0402 (1005 Metric) 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-2AEC1371X available in stock?

A: Yes. The ERA-2AEC1371X is an active product with 1094 Pcs in stock, providing immediate availability for production requirements.

Q: Do both parts have the same RoHS and moisture sensitivity ratings?

A: Yes. Both the ERA-2HEC1371P and ERA-2AEC1371X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.
