HCNR201#550 Equivalent & Substitute Parts

Part Overview

The HCNR201#550 is an optoisolator with photovoltaic linearized output manufactured by Broadcom Limited. This component provides 5000Vrms isolation in a single-channel configuration with DC input and photovoltaic output. The part is currently active in production status. Substitute parts are identified when equivalent electrical performance and isolation characteristics are required but alternative packaging or compliance specifications are necessary for specific applications or inventory availability.

Substitute Part Grouping Explanation

Substitution of the HCNR201#550 is based on maintaining electrical equivalence across the following critical parameters: isolation voltage (5000Vrms), number of channels (1), input type (DC), output type (photovoltaic linearized), current transfer ratio range (0.36% to 0.72% @ 10mA), forward voltage (1.6V typical), maximum forward current (25 mA), and operating temperature range (-55°C to 100°C). The substitute part HCNR201-550E shares all these electrical specifications and is derived from the same base product number (HCNR201). Packaging and compliance differences do not affect functional substitution when circuit board layout and regulatory requirements permit.

Engineering Selection Recommendations

The HCNR201#550 and HCNR201-550E are electrically equivalent optoisolators with identical isolation voltage, channel count, transfer ratio specifications, and operating temperature range. Selection between these parts is determined by packaging requirements and regulatory compliance. The HCNR201#550 is supplied in Tape & Reel packaging and carries RoHS non-compliant status. The HCNR201-550E is supplied in Cut Tape and Digi-Reel® packaging with ROHS3 compliance. Both parts maintain the same 8-SMD Gull Wing package configuration and surface mount mounting type. Applications requiring RoHS3 compliance should specify HCNR201-550E. Applications with no RoHS requirement and preference for Tape & Reel packaging may use HCNR201#550. Both parts share identical electrical performance and are suitable for direct substitution in circuit designs where packaging format and compliance certifications are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can HCNR201-550E replace HCNR201#550 in existing designs?

A: Yes. Both parts are electrically identical with matching isolation voltage (5000Vrms), current transfer ratio (0.36% to 0.72% @ 10mA), forward voltage (1.6V), and operating temperature range (-55°C to 100°C). The primary differences are packaging format (Tape & Reel versus Cut Tape/Digi-Reel®) and RoHS compliance status. Circuit-level substitution is valid when packaging and compliance requirements are satisfied.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: isolation voltage (5000Vrms), number of channels (1), input type (DC), output type (photovoltaic linearized), current transfer ratio range (0.36% to 0.72% @ 10mA), forward voltage (1.6V typical), maximum forward current (25 mA), and operating temperature range (-55°C to 100°C). All these parameters are identical between HCNR201#550 and HCNR201-550E.

Q: Does the packaging difference affect electrical performance?

A: No. The packaging difference (Tape & Reel versus Cut Tape/Digi-Reel®) is a supply format distinction and does not affect electrical characteristics, isolation performance, or circuit functionality. Both packaging formats contain the same 8-SMD Gull Wing component.

Q: What is the significance of RoHS compliance difference?

A: HCNR201#550 is RoHS non-compliant, while HCNR201-550E is ROHS3 compliant. Applications subject to RoHS regulations or customer requirements for RoHS3 compliance must use HCNR201-550E. Applications without RoHS requirements may use either part.

Q: Are both parts currently in production?

A: Yes. Both HCNR201#550 and HCNR201-550E carry Active product status from Broadcom Limited, indicating current production availability.
