HCPL2630SV Equivalent & Substitute Parts

Part Overview

The HCPL2630SV is a logic output optoisolator manufactured by onsemi, designed for high-speed digital isolation applications. This 2-channel device provides 2500Vrms isolation with 10Mbps data rate capability and open collector outputs. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement planning. Active alternatives with compatible electrical and mechanical specifications are available to maintain system functionality and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL2630SV is determined by strict equivalence across the following critical parameters:

• Channel Configuration: 2 channels with 2 inputs on Side 1, 0 inputs on Side 2
• Isolation Voltage: 2500Vrms minimum
• Common Mode Transient Immunity: 10kV/µs (Typ)
• Output Architecture: Open Collector topology
• Output Current: 50 mA per channel
• Data Rate: 10Mbps
• Propagation Delay: 75ns maximum (both tpLH and tpHL)
• Supply Voltage Range: 4.5V to 5.5V
• Temperature Range: -40°C to 85°C
• Package: 8-SMD, Gull Wing surface mount

The HCPL2630SVM qualifies as a direct substitute based on matching all electrical specifications and package requirements. The primary distinction is enhanced output stage design (Schottky Clamped output) and active product status, which provides improved long-term availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The HCPL2630SVM is the recommended substitute for the obsolete HCPL2630SV. Both components maintain identical electrical performance across all critical isolation, timing, and output specifications. The HCPL2630SVM offers the following advantages:

• Active Product Status: Ensures ongoing manufacturing support and long-term availability
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status
• Enhanced Output Design: Schottky Clamped output stage provides improved switching characteristics and reduced parasitic effects
• Identical Package: 8-SMD Gull Wing surface mount configuration allows direct PCB layout compatibility
• Supply Chain Continuity: Higher inventory levels (12,880 Pcs vs. 5,900 Pcs) support production requirements

No design modifications are required for substitution. Pin configuration, electrical interface, and thermal characteristics remain unchanged between the two parts.

Frequently Asked Questions (FAQ)

Q: Can HCPL2630SVM be used as a direct replacement for HCPL2630SV in existing designs?

A: Yes. The HCPL2630SVM is electrically and mechanically equivalent to the HCPL2630SV. All critical parameters including isolation voltage, data rate, propagation delay, output current, and supply voltage specifications are identical. The 8-SMD Gull Wing package is unchanged, allowing direct PCB substitution without layout modifications.

Q: What is the difference between standard open collector and Schottky Clamped output?

A: The HCPL2630SVM features a Schottky Clamped output stage, which provides faster switching transitions and reduced voltage overshoot compared to standard open collector designs. Both output types maintain the same 50 mA output current rating and 75ns propagation delay specifications required for this application.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the HCPL2630SV and HCPL2630SVM maintain identical regulatory status: ROHS3 compliant, REACH unaffected, and MSL 1 (Unlimited). Both parts carry the same ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Q: Why is the HCPL2630SV listed as obsolete?

A: The HCPL2630SV has been superseded by the HCPL2630SVM, which offers improved output stage design and active manufacturing status. onsemi continues to support the HCPL2630 base product line through the active HCPL2630SVM variant.

Q: What is the impact of the Schottky Clamped output on circuit design?

A: The Schottky Clamped output maintains full compatibility with existing circuit designs. No pull-up resistor values, load impedance calculations, or signal conditioning changes are required. The output voltage and current characteristics remain within the same specifications as the standard open collector version.

Q: Are there any temperature or environmental considerations for substitution?

A: Both parts operate across the identical temperature range of -40°C to 85°C and maintain MSL 1 (Unlimited) moisture sensitivity rating. No environmental or thermal management changes are necessary when substituting the HCPL2630SVM for the HCPL2630SV.
