Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HRB1131X is determined by the following critical parameters:

• Resistance value: 1.13 kOhms
• Tolerance: ±0.1%
• Power rating: 0.063W (1/16W) minimum
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• RoHS compliance: ROHS3 Compliant

The ERA-2ARB1131X qualifies as a direct substitute based on matching all electrical specifications and package requirements. The primary distinction is product status and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARB1131X is the qualified substitute for the obsolete ERA-2HRB1131X. Both parts are manufactured by Panasonic Electronic Components and share identical electrical and mechanical specifications: 1.13 kOhms resistance, ±0.1% tolerance, 0.063W power rating, thin film composition, and 0402 package format.

The ERA-2ARB1131X offers extended operating temperature capability (-55°C to 155°C versus -55°C to 125°C) and carries active product status, ensuring continued availability. The substitute includes AEC-Q200 automotive qualification, providing additional reliability assurance. Both parts maintain ROHS3 compliance and MSL 1 rating.

Selection of the ERA-2ARB1131X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARB1131X be used as a direct replacement for ERA-2HRB1131X?

A: Yes. Both parts share identical resistance (1.13 kOhms), tolerance (±0.1%), power rating (0.063W), package (0402), and temperature coefficient (±10ppm/°C). The ERA-2ARB1131X is electrically and mechanically interchangeable.

Q: What is the primary difference between these parts?

A: The ERA-2HRB1131X is obsolete, while the ERA-2ARB1131X is active. The substitute offers extended operating temperature range (-55°C to 155°C) and includes AEC-Q200 automotive qualification.

Q: Are there packaging differences?

A: Both parts use 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: Do both parts meet RoHS requirements?

A: Yes. Both ERA-2HRB1131X and ERA-2ARB1131X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Is the higher temperature rating of ERA-2ARB1131X a concern for standard applications?

A: No. The extended temperature range of the substitute (-55°C to 155°C) is a superset of the original specification (-55°C to 125°C), ensuring compatibility across all original operating conditions.
