HCPL-7520-300 Current Sense Amplifier Equivalent & Substitute Parts

Part Overview

The HCPL-7520-300 is an active current sense amplifier manufactured by Broadcom Limited, designed for precision current measurement applications. This linear amplifier integrates one sensing circuit in an 8-DIP Gull Wing surface mount package. The device operates across a 4.5V to 5.5V supply range with a -3dB bandwidth of 100 kHz, making it suitable for real-time current monitoring in industrial and consumer electronics applications.

The HCPL-7520-300 maintains Active product status. Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and address specific compliance requirements such as RoHS certification for end-product applications.

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-7520-300 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: Current Sense
• Number of Circuits: 1
• -3dB Bandwidth: 100 kHz
• Current - Input Bias: 600 nA
• Voltage - Input Offset: 600 µV
• Current - Supply: 11.7 mA
• Current - Output / Channel: 16 mA
• Voltage - Supply Span: 4.5V to 5.5V
• Operating Temperature Range: -40°C to 85°C

Mechanical Equivalence Criteria:

• Package / Case: 8-SMD, Gull Wing
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts must match these parameters exactly. Variations in any electrical or mechanical specification disqualify a part from direct substitution.

Engineering Selection Recommendations

HCPL-7520-300E as Primary Substitute:

The HCPL-7520-300E is electrically and mechanically identical to the HCPL-7520-300 across all functional parameters. Both devices are manufactured by Broadcom Limited and maintain Active product status.

The primary distinction between these parts is regulatory compliance. The HCPL-7520-300E carries ROHS3 Compliant certification, while the HCPL-7520-300 is RoHS non-compliant. This difference is significant for applications subject to RoHS Directive requirements in the European Union and equivalent regulations in other jurisdictions.

Selection Criteria:

• Use HCPL-7520-300E when RoHS compliance is required for the end product or when supply chain policies mandate RoHS-compliant components.
• Use HCPL-7520-300 when RoHS compliance is not a requirement and the non-compliant variant is available.

Both parts are suitable for identical circuit implementations without design modification. Inventory availability should be considered as a secondary factor: HCPL-7520-300E currently has 5587 units in stock, while HCPL-7520-300 has 942 units in stock.

Frequently Asked Questions (FAQ)

Q: Can HCPL-7520-300E replace HCPL-7520-300 in an existing design?

A: Yes. The HCPL-7520-300E is electrically and mechanically equivalent to the HCPL-7520-300. All electrical parameters, package specifications, and operating characteristics are identical. No circuit redesign or PCB modification is required.

Q: What is the difference between HCPL-7520-300 and HCPL-7520-300E?

A: The HCPL-7520-300E is ROHS3 Compliant, while the HCPL-7520-300 is RoHS non-compliant. All other specifications are identical.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance refers to the materials and manufacturing process used to produce the component, not its electrical performance. Both variants deliver identical functional characteristics.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both HCPL-7520-300 and HCPL-7520-300E operate across -40°C to 85°C (TA).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use identical 8-SMD Gull Wing surface mount packaging. No footprint or assembly process changes are required.

Q: Which part should I select for a new design?

A: If RoHS compliance is required for your end product or supply chain, select HCPL-7520-300E. If RoHS compliance is not a requirement, either part is acceptable based on availability and cost considerations.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
