Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HRB1182P is determined by the following critical parameters:

• Resistance value: 11.8 kOhms
• Tolerance: ±0.1%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• RoHS compliance: ROHS3

The ERA-2ARB1182X meets all these electrical and mechanical specifications. This substitute maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics while offering enhanced operating temperature range and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARB1182X is the direct substitute for the obsolete ERA-2HRB1182P. Both parts share identical electrical specifications (11.8 kOhms ±0.1%, 0.063W, ±10ppm/°C) and mechanical compatibility (0402 package, 1.00mm × 0.50mm dimensions).

The ERA-2ARB1182X offers two advantages: active product status ensuring ongoing availability, and AEC-Q200 automotive qualification. The extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) provides additional thermal margin. Both parts maintain ROHS3 compliance and MSL 1 rating.

Selection of ERA-2ARB1182X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for ERA-2HRB1182P.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARB1182X directly replace ERA-2HRB1182P in existing designs?

A: Yes. Both parts are identical in resistance (11.8 kOhms), tolerance (±0.1%), power rating (0.063W), package (0402), and thermal characteristics (±10ppm/°C). Physical dimensions and termination count are identical, enabling direct PCB-level substitution.

Q: What is the difference between ERA-2HRB1182P and ERA-2ARB1182X?

A: The ERA-2ARB1182X is an active product with AEC-Q200 automotive qualification and extended operating temperature range (-55°C to 155°C). The ERA-2HRB1182P is obsolete with a standard operating range of -55°C to 125°C. All electrical parameters are identical.

Q: Are there packaging differences between these parts?

A: The ERA-2HRB1182P is available in standard packaging. The ERA-2ARB1182X is supplied in Tape & Reel (TR) format. Both use identical 0402 (1005 Metric) package specifications with 1.00mm × 0.50mm dimensions and 0.40mm maximum seated height.

Q: Does the extended temperature range of ERA-2ARB1182X affect circuit performance?

A: No. The extended range (-55°C to 155°C versus -55°C to 125°C) represents enhanced capability. Both parts maintain ±10ppm/°C temperature coefficient across their respective operating ranges. Designs operating within -55°C to 125°C experience identical performance characteristics.

Q: Is AEC-Q200 certification required for my application?

A: AEC-Q200 certification is specific to automotive applications. For non-automotive designs, both parts are functionally equivalent. The certification does not affect electrical performance in non-automotive environments.
