HCPL0630 Equivalent & Substitute Parts

Part Overview

The HCPL0630 is a logic output optoisolator manufactured by onsemi, featuring 2-channel open collector configuration with Schottky clamping and 3750Vrms isolation voltage. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The part operates at 10Mbps data rate with 50mA output current per channel and is housed in an 8-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL0630 are identified based on the following critical parameters that determine functional compatibility:

• Number of Channels: Must be 2 channels
• Voltage - Isolation: Minimum 3750Vrms (equal or higher acceptable)
• Input Type: DC
• Output Type: Open Collector or Open Drain configuration
• Current - Output / Channel: 50 mA capability
• Data Rate: 10Mbps or higher
• Voltage - Supply: 4.5V ~ 5.5V range
• Package / Case: 8-SOIC form factor
• Mounting Type: Surface Mount

Two substitute parts meet these criteria: HCPL-0630 (Broadcom Limited) and VO0630T (Vishay Semiconductor Opto Division). Both maintain the core electrical specifications and physical package requirements necessary for direct substitution in applications designed for the HCPL0630.

Parameter Comparison

Engineering Selection Recommendations

HCPL-0630 (Broadcom Limited): This part is functionally equivalent to the HCPL0630 with identical isolation voltage, output configuration, and channel count. The Broadcom variant maintains active product status, ensuring long-term availability and supply chain stability. Propagation delay specifications are slightly relaxed (100ns vs. 75ns), which is acceptable for most applications operating at 10Mbps. This part is classified as RoHS non-compliant, which may be a consideration for regulated applications.

VO0630T (Vishay Semiconductor Opto Division): This part provides higher isolation voltage (4000Vrms vs. 3750Vrms) and extended operating temperature range (-40°C to 100°C vs. -40°C to 85°C). The output configuration differs as open drain rather than open collector with Schottky clamping. The VO0630T is RoHS3 compliant, meeting environmental and regulatory requirements for modern applications. This part is actively produced with substantial inventory availability.

Frequently Asked Questions (FAQ)

Q: Can HCPL-0630 directly replace HCPL0630 in existing designs?

A: Yes. The HCPL-0630 from Broadcom maintains identical electrical specifications for isolation voltage, channel count, output current, data rate, and supply voltage. Pin configuration and package dimensions are equivalent. The primary difference is slightly increased propagation delay (100ns vs. 75ns), which does not affect functionality at 10Mbps operation.

Q: What is the key difference between HCPL-0630 and VO0630T?

A: The primary difference is output configuration: HCPL-0630 uses open collector with Schottky clamping, while VO0630T uses open drain. Both support 50mA output current and 10Mbps data rate. VO0630T provides higher isolation voltage (4000Vrms) and extended temperature range. Circuit design must account for the output stage topology difference.

Q: Is the VO0630T suitable for applications requiring Schottky clamping?

A: The VO0630T uses open drain output without integrated Schottky clamping. Applications requiring Schottky clamping characteristics must use HCPL-0630 or HCPL0630. External clamping diodes can be added to VO0630T designs if necessary.

Q: Are all three parts available in the same packaging?

A: Yes. HCPL0630, HCPL-0630, and VO0630T are all housed in 8-SOIC (0.154", 3.90mm Width) surface mount packages with identical pin counts and footprints, enabling direct PCB layout compatibility.

Q: Which substitute part has better long-term availability?

A: Both HCPL-0630 (Broadcom) and VO0630T (Vishay) are active products with established supply chains. The original HCPL0630 is obsolete. For new designs, either substitute is suitable; for legacy system support, either provides continuity.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is a regulatory requirement for products sold in certain markets. HCPL-0630 is RoHS non-compliant, while VO0630T is RoHS3 compliant. Select based on your product's regulatory requirements and target markets.
