Substitute Part Grouping Explanation

Substitute parts for the ERA-2HRC73R2P must maintain electrical and mechanical compatibility based on the following critical parameters:

• Resistance value: 73.2 Ohms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power rating: 0.063W minimum (1/16W)
• Package: 0402 (1005 Metric) form factor
• Composition: Thin film construction
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: minimum -55°C ~ 125°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 or better

The ERA-2ARC73R2X qualifies as a direct substitute. It matches all electrical specifications and package requirements while offering an extended operating temperature range (-55°C ~ 155°C) and automotive AEC-Q200 qualification. The ERA-2ARC73R2X maintains active product status, ensuring ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2ARC73R2X is the qualified substitute for the obsolete ERA-2HRC73R2P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications (73.2 Ohms ±0.25%, 0.063W, ±10ppm/°C) and mechanical form factor (0402 package).

The ERA-2ARC73R2X offers two advantages: active product status ensures continued supply chain availability, and extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides broader application flexibility. The ERA-2ARC73R2X includes AEC-Q200 automotive qualification, which does not restrict use in non-automotive applications.

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERA-2ARC73R2X replace ERA-2HRC73R2P in all applications?

A: Yes. The ERA-2ARC73R2X matches all critical electrical parameters (resistance, tolerance, power rating, temperature coefficient) and mechanical specifications (0402 package, dimensions, terminations). The extended temperature range of the substitute provides equal or greater capability for the specified operating range of the original part.

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

A: The ERA-2H series (obsolete) and ERA-2A series (active) are both Panasonic thin film chip resistor lines. The ERA-2A series includes automotive AEC-Q200 qualification and extended temperature range. Electrical performance and package form factor remain equivalent.

Q: Are there any PCB layout or assembly considerations when substituting ERA-2ARC73R2X for ERA-2HRC73R2P?

A: No. Both parts use identical 0402 (1005 Metric) package dimensions (0.039" L x 0.020" W, 0.016" max height) and 2-termination configuration. PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Does AEC-Q200 qualification on ERA-2ARC73R2X affect non-automotive applications?

A: No. AEC-Q200 qualification indicates the part meets automotive reliability standards. This certification does not restrict use in non-automotive applications and does not alter electrical or mechanical performance.

Q: What is the inventory status for these parts?

A: ERA-2HRC73R2P (obsolete): 850 Pcs in stock. ERA-2ARC73R2X (active): 796 Pcs in stock. For long-term supply assurance, the active ERA-2ARC73R2X is the recommended selection.
