HCPL2630S Equivalent & Substitute Parts

Part Overview

The HCPL2630S is a logic output optoisolator manufactured by onsemi, designed for high-speed digital isolation applications. This 2-channel device provides 2500Vrms isolation with open collector outputs, operating at 10Mbps data rate. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL2630S is determined by the following critical parameters:

• Channel Configuration: 2 channels with 2 inputs on Side 1, 0 inputs on Side 2
• Output Architecture: Open collector topology
• Data Rate: 10Mbps maximum
• Package Type: 8-SMD, Gull Wing surface mount
• Supply Voltage Range: 4.5V to 5.5V
• Input Type: DC
• Common Mode Transient Immunity: 10kV/µs (Typ)

The HCPL2630SM qualifies as a direct substitute based on matching channel configuration, output type, data rate, package format, and supply voltage specifications. Both devices share the same base product number (HCPL2630) and are manufactured by onsemi using compatible 8-SMD packaging.

Parameter Comparison

Engineering Selection Recommendations

The HCPL2630SM is the manufacturer-recommended substitute for the obsolete HCPL2630S. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system replacements.

The HCPL2630SM provides enhanced isolation voltage (5000Vrms versus 2500Vrms), supporting applications requiring higher isolation margins. The extended operating temperature range (-40°C to 110°C versus -40°C to 85°C) accommodates broader environmental conditions.

Output current per channel is reduced from 50 mA to 25 mA on the substitute. Circuit designs must verify that load requirements do not exceed 25 mA per channel. The identical propagation delay specifications (75ns maximum for both tpLH and tpHL) and matching data rate (10Mbps) ensure timing compatibility in digital isolation applications.

Both devices use identical 8-SMD, Gull Wing packaging, permitting direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can HCPL2630SM directly replace HCPL2630S in existing designs?

A: Yes, for applications where output current requirements do not exceed 25 mA per channel. The identical package format (8-SMD, Gull Wing), matching data rate (10Mbps), and equivalent propagation delay specifications support direct substitution. Verify that your circuit design does not require the higher 50 mA output current of the original device.

Q: What is the primary difference between these two parts?

A: The HCPL2630SM provides doubled isolation voltage (5000Vrms versus 2500Vrms) and reduced output current capability (25 mA versus 50 mA per channel). The substitute also extends the operating temperature range to 110°C maximum.

Q: Are there any compliance or regulatory differences?

A: No. Both the HCPL2630S and HCPL2630SM maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited), ensuring equivalent regulatory standing.

Q: Will the HCPL2630SM work with the same PCB layout?

A: Yes. Both devices use the 8-SMD, Gull Wing package format with identical pinout and footprint, requiring no PCB modifications for component substitution.

Q: What should I verify before implementing the HCPL2630SM?

A: Confirm that your circuit design operates within the 25 mA maximum output current per channel specification. Verify that the extended operating temperature range of the substitute (-40°C to 110°C) meets or exceeds your application requirements. Confirm that the higher isolation voltage (5000Vrms) does not introduce any design conflicts.
