Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HRB93R1P is determined by the following critical parameters:

• Resistance Value: Must be 93.1 Ohms
• Tolerance: Must be ±0.1% 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 ±10ppm/°C or better
• RoHS Compliance: Must maintain ROHS3 Compliant status

The ERA-2ARB93R1X qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering enhanced product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARB93R1X is the qualified substitute for the obsolete ERA-2HRB93R1P. Both parts are manufactured by Panasonic Electronic Components and maintain identical electrical specifications: 93.1 Ohms resistance, ±0.1% tolerance, 0.063W power rating, and ±10ppm/°C temperature coefficient in 0402 package format.

The ERA-2ARB93R1X offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides broader thermal performance envelope
• AEC-Q200 automotive qualification adds reliability certification for demanding applications
• Identical RoHS3 compliance and MSL rating maintain regulatory and environmental requirements

Pin-to-pin and footprint compatibility is guaranteed due to identical 0402 package specifications and two-termination configuration.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARB93R1X be used as a direct replacement for ERA-2HRB93R1P?

A: Yes. Both parts share identical resistance value (93.1 Ohms), tolerance (±0.1%), power rating (0.063W), package format (0402), composition (thin film), and temperature coefficient (±10ppm/°C). Footprint and electrical performance are fully compatible.

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

A: The ERA-2A series (represented by ERA-2ARB93R1X) is the active production line with AEC-Q200 automotive qualification and extended temperature range (-55°C ~ 155°C). The ERA-2H series (ERA-2HRB93R1P) is obsolete. Both series maintain identical core electrical specifications for the 93.1 Ohm value.

Q: Does the extended temperature range of ERA-2ARB93R1X affect circuit design?

A: No. The extended upper temperature limit (155°C versus 125°C) is a performance enhancement that does not require design changes. Circuits designed for ERA-2HRB93R1P operate within the ERA-2ARB93R1X temperature specification.

Q: Are there any package or footprint differences?

A: No. Both parts use identical 0402 (1005 Metric) package with 0.039" L x 0.020" W dimensions and 0.016" maximum seated height. PCB footprints are interchangeable.

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

A: AEC-Q200 certification is a value-added feature of ERA-2ARB93R1X. If your application requires automotive-grade reliability qualification, ERA-2ARB93R1X meets this requirement. For non-automotive applications, both parts satisfy identical electrical and environmental specifications.
