• Voltage - Isolation: 3750Vrms
• Common Mode Transient Immunity: 10kV/µs
• Output Type: Open Collector, Schottky Clamped
• Current - Output / Channel: 50 mA
• Data Rate: 10MBd
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C

Mechanical Parameters (Must Match):

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Allowed Variations:

All identified substitutes maintain identical electrical performance and physical form factor, differing only in packaging configuration and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

HCPL-0631-500E is the primary substitute for HCPL-0631#500. Both parts are electrically and mechanically identical. HCPL-0631-500E is supplied in Cut Tape & Digi-Reel packaging and carries ROHS3 compliance certification, making it suitable for applications with RoHS requirements. Inventory availability is significantly higher (109,300 units).

HCPL-0631 and HCPL-0631-000E are alternative substitutes supplied in Tube packaging. HCPL-0631-000E provides ROHS3 compliance, while HCPL-0631 maintains the same RoHS non-compliant status as the original part. Both are suitable for applications where tube packaging is acceptable.

Selection between substitutes should be based on packaging requirements, regulatory compliance mandates, and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically identical to HCPL-0631#500?

A: Yes. All substitute parts maintain identical electrical specifications including isolation voltage (3750Vrms), data rate (10MBd), output current (50 mA), and timing characteristics. Differences exist only in packaging format and RoHS compliance status.

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

A: Tape & Reel (TR) and Cut Tape & Digi-Reel (CT) are automated assembly formats suitable for high-volume production. Tube packaging is used for lower-volume applications and manual assembly. All three formats contain the same 8-SOIC component with identical electrical performance.

Q: Can I use HCPL-0631-500E as a direct replacement for HCPL-0631#500?

A: Yes. HCPL-0631-500E is a direct substitute with identical electrical and mechanical specifications. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and ROHS3 compliance certification.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. If your application or region mandates RoHS compliance, select HCPL-0631-500E or HCPL-0631-000E. If RoHS compliance is not required, HCPL-0631#500 or HCPL-0631 are suitable.

Q: Are there any differences in operating temperature range between substitutes?

A: No. All parts operate across the identical temperature range of -40°C to 85°C.

Q: Which substitute has the best inventory availability?

A: HCPL-0631-500E has the highest inventory with 109,300 units in stock, compared to 726 units for HCPL-0631#500, 2,217 units for HCPL-0631, and 3,822 units for HCPL-0631-000E.
