HCPL-2631#500 Equivalent & Substitute Parts

Part Overview

The HCPL-2631#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 open collector, Schottky clamped outputs and supports data rates up to 10MBd. 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, compliance requirements, and inventory considerations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The HCPL-2631#500 and its identified substitute HCPL-2631-500E are direct equivalents from the same manufacturer base product line (HCPL-2631). Substitution is valid based on the following criteria:

Electrical Parameters (Identical):

• Isolation voltage: 3750Vrms
• Number of channels: 2
• Common mode transient immunity: 10kV/µs minimum
• Data rate: 10MBd
• Output configuration: Open collector, Schottky clamped
• Output current per channel: 50 mA
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Propagation delay: 100ns maximum (both tpLH and tpHL)
• Rise/fall time: 24ns typical rise, 10ns typical fall

Mechanical Parameters (Identical):

• Package type: 8-SMD, Gull Wing
• Mounting type: Surface Mount
• Input configuration: 2 inputs on Side 1, 0 inputs on Side 2

Differentiating Factor: The primary difference between these parts is packaging format: HCPL-2631#500 is supplied in Tape & Reel (TR) format, while HCPL-2631-500E is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats contain identical die and lead configurations suitable for automated assembly.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-2631#500 and HCPL-2631-500E are functionally equivalent and interchangeable at the circuit level. Selection between these parts should be based on the following factors:

HCPL-2631#500 (Tape & Reel):

• Suitable for high-volume production runs with automated pick-and-place equipment
• RoHS non-compliant status requires verification against end-product regulatory requirements
• Current inventory: 731 pieces

HCPL-2631-500E (Cut Tape & Digi-Reel®):

• Suitable for mixed-volume production or applications requiring flexible packaging formats
• ROHS3 compliant, meeting RoHS Directive 2011/65/EU requirements
• Significantly higher inventory availability: 18,440 pieces
• Recommended for new designs or applications with RoHS compliance mandates

Both parts maintain identical electrical performance, isolation ratings, and thermal operating ranges. The choice between packaging formats does not affect circuit functionality or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2631-500E be used as a direct replacement for HCPL-2631#500 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). No circuit modifications are required.

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

A: Tape & Reel (TR) format supplies components on a continuous reel suitable for high-speed automated assembly. Cut Tape (CT) & Digi-Reel® format provides components in cut tape segments on a reel, offering flexibility for lower-volume or mixed-component production runs. Both formats contain identical components with identical lead configurations.

Q: Are there compliance differences between these parts?

A: Yes. HCPL-2631#500 is RoHS non-compliant, while HCPL-2631-500E is ROHS3 compliant. Both are REACH Unaffected. For applications requiring RoHS compliance, HCPL-2631-500E is the appropriate selection.

Q: Do these parts have identical isolation voltage ratings?

A: Yes. Both HCPL-2631#500 and HCPL-2631-500E provide 3750Vrms isolation voltage with 10kV/µs common mode transient immunity.

Q: What is the maximum data rate for these optoisolators?

A: Both parts support a maximum data rate of 10MBd with propagation delays of 100ns maximum for both rising and falling edges.

Q: Are these parts suitable for -40°C to 85°C operating temperature applications?

A: Yes. Both HCPL-2631#500 and HCPL-2631-500E are rated for -40°C to 85°C operating temperature range.

Q: What is the output current capability per channel?

A: Both parts provide 50 mA maximum output current per channel with open collector, Schottky clamped output configuration.
