ERA-2HRC7151X Equivalent & Substitute Parts

Part Overview

The ERA-2HRC7151X is a 7.15 kOhms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W). Manufactured by Panasonic Electronic Components, this part operates across -55°C to 125°C with a temperature coefficient of ±10ppm/°C. The product is currently obsolete, necessitating identification of equivalent substitute components to maintain design continuity and ensure procurement availability for new production runs or field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ERA-2HRC7151X is determined by strict equivalence across the following parameters:

• Resistance value: 7.15 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum (1/16W)
• Composition: Thin film construction
• Package: 0402 (1005 Metric) form factor
• Temperature coefficient: ±10ppm/°C (exact match required)
• Termination count: 2-pin configuration
• RoHS compliance: ROHS3 Compliant minimum

The ERA-2ARC7151X meets all substitution criteria while offering enhanced operating temperature range (-55°C to 155°C) and automotive-grade qualification (AEC-Q200), making it a direct functional equivalent with extended environmental performance.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC7151X is the direct substitute for the obsolete ERA-2HRC7151X. Both components share identical electrical specifications (7.15 kOhms, ±0.25% tolerance, ±10ppm/°C temperature coefficient) and mechanical form factor (0402 package). The ERA-2ARC7151X maintains active product status with full ROHS3 compliance and MSL 1 rating, ensuring long-term availability and supply chain continuity.

The ERA-2ARC7151X incorporates AEC-Q200 automotive qualification and extends the maximum operating temperature to 155°C compared to the original 125°C specification. This enhanced thermal capability provides additional design margin for applications requiring extended temperature performance. The substitute is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC7151X be used as a direct replacement for ERA-2HRC7151X?

A: Yes. Both components have identical resistance (7.15 kOhms), tolerance (±0.25%), power rating (0.063W), composition (thin film), package (0402), and temperature coefficient (±10ppm/°C). The ERA-2ARC7151X is electrically and mechanically equivalent.

Q: What is the difference between ERA-2HRC7151X and ERA-2ARC7151X?

A: The primary differences are product status and operating temperature range. ERA-2HRC7151X is obsolete with -55°C to 125°C operation, while ERA-2ARC7151X is active with -55°C to 155°C operation and AEC-Q200 automotive qualification. Electrical performance is identical.

Q: Are there packaging differences between these parts?

A: The ERA-2HRC7151X uses standard packaging, while ERA-2ARC7151X is supplied in Tape & Reel (TR) format. Both use the same 0402 (1005 Metric) form factor and are compatible with standard SMD assembly equipment.

Q: Does the AEC-Q200 rating on ERA-2ARC7151X affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates enhanced reliability testing and quality assurance. It does not affect electrical or mechanical compatibility. The part functions identically in non-automotive applications.

Q: What is the MSL rating and why does it matter?

A: Both parts have MSL 1 (Unlimited) rating, meaning they have unlimited shelf life and require no special moisture control during storage or handling. This simplifies inventory management and reduces procurement constraints.
