HCPL-2232#500 Equivalent & Substitute Parts

Part Overview

The HCPL-2232#500 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 2-channel device provides 3750Vrms isolation with push-pull totem pole output configuration, supporting data rates up to 5MBd. The component is currently active in production and widely used in industrial control, power management, and communication interface circuits where galvanic isolation is required. Substitute parts are identified to address packaging format availability and compliance requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-2232#500 is determined by strict equivalence across the following critical parameters:

• Number of channels: 2
• Isolation voltage: 3750Vrms
• Common mode transient immunity: 10kV/µs minimum
• Output configuration: Push-pull, totem pole
• Output current per channel: 25 mA
• Data rate: 5MBd
• Propagation delay: 300ns maximum (both rising and falling edges)
• Supply voltage range: 4.5V to 20V
• Operating temperature range: -40°C to 85°C
• Package type: 8-SMD, Gull Wing
• Mounting type: Surface mount

The identified substitute part maintains identical electrical performance and mechanical compatibility. Differences are limited to packaging format (tape & reel versus cut tape with Digi-Reel) and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the HCPL-2232#500 and HCPL-2232-500E are active production components from Broadcom Limited with identical electrical specifications and mechanical compatibility. Selection between these parts is determined by regulatory and procurement requirements:

The HCPL-2232-500E is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring RoHS compliance. The HCPL-2232#500 is RoHS non-compliant and suitable for applications without such regulatory constraints.

Packaging format differs between the two parts. The HCPL-2232#500 is supplied in Tape & Reel format, while the HCPL-2232-500E is supplied in Cut Tape with Digi-Reel format. This distinction affects procurement volume requirements and handling procedures but does not impact electrical or mechanical performance.

Both parts maintain identical isolation voltage, CMTI rating, output current capability, data rate, propagation delay, supply voltage range, and operating temperature specifications. Direct substitution is electrically and mechanically valid in either direction, provided packaging format and compliance requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2232-500E be used as a direct replacement for HCPL-2232#500 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The HCPL-2232-500E provides the additional benefit of ROHS3 compliance. Substitution is valid provided the application does not have specific packaging format requirements that mandate Tape & Reel delivery.

Q: What is the difference between Tape & Reel and Cut Tape with Digi-Reel packaging?

A: Tape & Reel (TR) and Cut Tape (CT) with Digi-Reel represent different packaging and delivery formats. Tape & Reel is supplied as a continuous reel suitable for high-volume automated assembly. Cut Tape with Digi-Reel is supplied in smaller tape segments on a reel, accommodating lower-volume or mixed-component orders. Both formats contain identical components with no electrical or mechanical differences.

Q: Are there any performance differences between HCPL-2232#500 and HCPL-2232-500E?

A: No. Both parts have identical electrical performance specifications including isolation voltage, CMTI rating, output current, data rate, propagation delay, and operating temperature range. The only differences are packaging format and RoHS compliance status.

Q: What does ROHS3 compliance mean for the HCPL-2232-500E?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. This is required for applications subject to EU RoHS regulations or customer specifications mandating RoHS compliance.

Q: Can both parts be used interchangeably in the same PCB assembly process?

A: Yes, provided the assembly process accommodates the packaging format supplied. Both parts use identical 8-SMD Gull Wing packages and surface mount configuration. Tape & Reel and Cut Tape formats require different handling in automated pick-and-place equipment, but the components themselves are mechanically identical.

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

A: Both HCPL-2232#500 and HCPL-2232-500E have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage or handling.
