Key Parameters

Substitute Part Grouping Explanation

The HCPL2630SDM qualifies as a direct substitute for the HCPL2630SD based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Number of channels: 2
• Input type: DC
• Output type: Open Collector
• Data rate: 10Mbps
• Common mode transient immunity: 10kV/µs (Typ)
• Supply voltage range: 4.5V ~ 5.5V
• Package type: 8-SMD, Gull Wing
• Mounting type: Surface Mount
• Base product number: HCPL2630
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters (Within Acceptable Substitution Scope):

• Isolation voltage: 5000Vrms (vs. 2500Vrms in main part)
• Output current per channel: 25 mA (vs. 50 mA in main part)
• Operating temperature range: -40°C ~ 110°C (vs. -40°C ~ 85°C in main part)
• Product status: Active (vs. Obsolete in main part)
• Packaging format: Tape & Reel (vs. Cut Tape in main part)

The HCPL2630SDM provides enhanced isolation voltage and extended temperature range, making it suitable for applications where the HCPL2630SD is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The HCPL2630SDM is the manufacturer-recommended substitute for the obsolete HCPL2630SD. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory consistency in component selection.

The HCPL2630SDM offers superior isolation voltage (5000Vrms versus 2500Vrms), providing enhanced safety margins in high-voltage isolation applications. The extended operating temperature range (-40°C to 110°C versus -40°C to 85°C) accommodates broader environmental conditions.

The reduction in maximum output current per channel (25 mA versus 50 mA) requires circuit-level evaluation to confirm compatibility with existing load requirements. Applications drawing less than 25 mA per channel output will experience no functional impact.

The active product status of the HCPL2630SDM ensures ongoing availability and manufacturing support, eliminating supply chain risk associated with obsolete components.

Frequently Asked Questions (FAQ)

Q: Can the HCPL2630SDM directly replace the HCPL2630SD in existing designs?

A: The HCPL2630SDM is electrically compatible for applications where output current requirements do not exceed 25 mA per channel. The identical pin configuration, package type (8-SMD, Gull Wing), and supply voltage range (4.5V ~ 5.5V) enable direct PCB-level substitution. The enhanced isolation voltage and extended temperature range present no compatibility issues.

Q: What is the impact of the reduced output current specification?

A: The HCPL2630SDM specifies 25 mA maximum output current per channel, compared to 50 mA for the HCPL2630SD. Designs operating within the 25 mA limit experience no functional change. Applications requiring higher output current must implement external buffering or alternative component selection.

Q: Are there packaging differences between these parts?

A: The HCPL2630SD is supplied in Cut Tape (CT) packaging, while the HCPL2630SDM is supplied in Tape & Reel (TR) format. Both use identical 8-SMD, Gull Wing physical packages suitable for surface mount assembly. Tape & Reel packaging is standard for high-volume production environments.

Q: Do both parts meet the same compliance standards?

A: Both the HCPL2630SD and HCPL2630SDM are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory compliance is maintained across the substitution.

Q: Why is the HCPL2630SD classified as obsolete?

A: The HCPL2630SD has reached end-of-life status within onsemi's product portfolio. The HCPL2630SDM represents the active continuation of this product line with enhanced specifications and ongoing manufacturing support.
