Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-7720#500 are qualified based on strict equivalence across the following critical parameters:

• Number of Channels: 1
• Voltage - Isolation: 3750Vrms
• Common Mode Transient Immunity (Min): 10kV/µs
• Input Type: Logic
• Output Type: Push-Pull, Totem Pole
• Current - Output / Channel: 10 mA
• Data Rate: 25MBd
• Propagation Delay tpLH / tpHL (Max): 40ns, 40ns
• Rise / Fall Time (Typ): 9ns, 8ns
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 8-SMD, Gull Wing
• Mounting Type: Surface Mount

The primary difference between the main part and its substitute is the packaging format and RoHS compliance status. Both parts share the same base product number (HCPL-7720) and deliver identical electrical performance and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-7720#500 and HCPL-7720-500E are active production components from Broadcom Limited with identical electrical specifications and thermal operating ranges. Selection between these parts should be based on the following criteria:

HCPL-7720#500 is supplied in Tape & Reel (TR) packaging format and carries RoHS non-compliant status. This part is suitable for applications where RoHS compliance is not a regulatory requirement.

HCPL-7720-500E is supplied in Cut Tape (CT) & Digi-Reel® packaging format and is ROHS3 compliant. This part is required for applications subject to RoHS3 regulations and for customers with mandatory RoHS compliance policies. The alternative packaging format provides flexibility in component procurement and handling workflows.

Both parts maintain identical isolation voltage, CMTI rating, output current, data rate, propagation delay, and thermal specifications, ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can HCPL-7720-500E be used as a direct replacement for HCPL-7720#500 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including isolation voltage (3750Vrms), CMTI (10kV/µs), output current (10 mA), data rate (25MBd), propagation delay (40ns), and operating temperature range (-40°C to 85°C). The only differences are packaging format and RoHS compliance status.

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

A: Tape & Reel (TR) is a continuous reel format for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides flexibility for lower-volume orders and mixed component procurement. Both formats contain the same component in the same 8-SMD, Gull Wing package configuration.

Q: Which part should be selected for RoHS-regulated applications?

A: HCPL-7720-500E is ROHS3 compliant and must be used for applications subject to RoHS3 regulations. HCPL-7720#500 is RoHS non-compliant and is not suitable for RoHS-regulated environments.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance, including propagation delay, rise/fall time, output current, and isolation characteristics. Performance is determined by the base product number (HCPL-7720) and is consistent across both variants.

Q: What is the inventory status for these parts?

A: HCPL-7720#500 has 928 pieces in stock. HCPL-7720-500E has 5200 pieces in stock. Availability may vary based on current demand and supply conditions.
