Substitute Part Grouping Explanation

Substitution of the ERA-2HRB2371P is based on electrical and mechanical parameter equivalence within the thin film chip resistor category. The following parameters must remain constant for direct substitution:

• Resistance value: 2.37 kOhms
• Tolerance: ±0.1%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Number of terminations: 2

The ERA-2ARB2371X qualifies as a direct substitute because it maintains all critical electrical specifications and mechanical compatibility while offering enhanced product status and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARB2371X is the qualified substitute for the obsolete ERA-2HRB2371P. Both components share identical electrical specifications and mechanical compatibility. The ERA-2ARB2371X offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• AEC-Q200 automotive qualification provides additional reliability assurance for applications requiring automotive-grade components
• Extended operating temperature range (-55°C ~ 155°C) compared to the main part (-55°C ~ 125°C) provides broader thermal performance capability
• ROHS3 compliance and unlimited moisture sensitivity level maintained across both parts

Selection of the ERA-2ARB2371X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for the ERA-2HRB2371P.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARB2371X be used as a direct replacement for ERA-2HRB2371P?

A: Yes. Both components have identical resistance (2.37 kOhms), tolerance (±0.1%), power rating (0.063W), package (0402), and temperature coefficient (±10ppm/°C). Physical dimensions and termination count are identical, ensuring PCB compatibility without design modification.

Q: What is the difference between ERA-2HRB2371P and ERA-2ARB2371X?

A: The ERA-2ARB2371X is an active product with AEC-Q200 automotive qualification and an extended operating temperature range to 155°C, compared to the obsolete ERA-2HRB2371P with a 125°C maximum. All electrical and mechanical specifications remain equivalent.

Q: Are there packaging differences between these parts?

A: The ERA-2HRB2371P is available in standard packaging, while the ERA-2ARB2371X is supplied in Tape & Reel (TR) format. Both use the 0402 (1005 Metric) package with identical physical dimensions and height specifications.

Q: Is the ERA-2ARB2371X suitable for automotive applications?

A: The ERA-2ARB2371X carries AEC-Q200 qualification, making it suitable for automotive applications. The ERA-2HRB2371P does not have automotive qualification.

Q: Will substituting ERA-2ARB2371X require PCB layout changes?

A: No. Both components have identical dimensions (0.039" L x 0.020" W) and height (0.016" maximum), ensuring footprint compatibility without PCB redesign.
