Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ERA-2HRB1370P is based on strict equivalence of the following critical parameters:

• Resistance value: 137 Ohms
• Tolerance: ±0.1%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2ARB1370X meets all substitution criteria while offering extended operating temperature range (-55°C to 155°C) and automotive-grade qualification (AEC-Q200), making it a direct functional replacement with enhanced environmental performance.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARB1370X is the direct substitute for the obsolete ERA-2HRB1370P. Both components share identical electrical specifications (137 Ohms ±0.1%, 0.063W, ±10ppm/°C) and mechanical dimensions (0402 package). The ERA-2ARB1370X maintains active product status with full ROHS3 compliance and MSL 1 rating, ensuring supply chain continuity.

The ERA-2ARB1370X provides an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and carries AEC-Q200 automotive qualification. These enhancements do not compromise compatibility with applications designed for the original part and provide additional performance margin for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARB1370X be used as a direct replacement for ERA-2HRB1370P?

A: Yes. Both parts are 137 Ohms ±0.1% thin film resistors in 0402 package with identical power ratings (0.063W), temperature coefficients (±10ppm/°C), and physical dimensions. The ERA-2ARB1370X is electrically and mechanically compatible.

Q: What is the difference between ERA-2HRB and ERA-2ARB series?

A: The ERA-2ARB series includes automotive-grade AEC-Q200 qualification and extended temperature range (-55°C to 155°C) compared to the standard ERA-2HRB series (-55°C to 125°C). Both use identical thin film technology and tolerance specifications.

Q: Are there any PCB layout or assembly considerations when substituting ERA-2ARB1370X for ERA-2HRB1370P?

A: No. Both components use the same 0402 (1005 Metric) package with identical footprint dimensions (1.00mm x 0.50mm length and width, 0.40mm maximum seated height). No PCB redesign or assembly process changes are required.

Q: Is ERA-2ARB1370X RoHS compliant?

A: Yes. The ERA-2ARB1370X is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original ERA-2HRB1370P.

Q: Why should I use ERA-2ARB1370X instead of ERA-2HRB1370P?

A: The ERA-2HRB1370P is obsolete. The ERA-2ARB1370X is an active product from the same manufacturer with superior environmental specifications and automotive qualification, ensuring long-term availability and performance reliability.
