Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-7720 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms
• Number of channels: 1
• Output configuration: Push-Pull, Totem Pole
• Data rate: 25MBd
• Common mode transient immunity: 10kV/µs minimum
• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C

The identified substitute part HCPL-7720-000E maintains all electrical and mechanical specifications identical to the base part. Variation exists only in packaging format (tube versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-7720 and HCPL-7720-000E are active production parts from Broadcom Limited with identical electrical and mechanical performance characteristics. Selection between these parts depends on specific project requirements:

HCPL-7720 is suitable for applications where RoHS compliance is not a regulatory requirement and standard packaging is acceptable.

HCPL-7720-000E is the appropriate selection for designs requiring ROHS3 compliance. This variant is supplied in tube packaging and maintains all functional specifications of the base part. The higher inventory availability (5900 pcs versus 2220 pcs) may also support production scheduling requirements.

Both parts share identical isolation voltage, data rate, propagation delay, and thermal operating range, ensuring direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can HCPL-7720-000E be used as a direct replacement for HCPL-7720 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The HCPL-7720-000E differs only in packaging format (tube) and RoHS compliance status. No circuit modifications are required for substitution.

Q: What is the difference between standard packaging and tube packaging?

A: Tube packaging affects component handling and storage but does not alter electrical performance. Tube packaging is typically used for automated assembly processes and higher-volume production runs.

Q: Does RoHS3 compliance affect the component's electrical performance?

A: No. RoHS3 compliance indicates material composition restrictions but does not change the electrical specifications, isolation voltage, data rate, or output characteristics of the HCPL-7720-000E.

Q: Are the propagation delay and rise/fall time specifications identical between both parts?

A: Yes. Both HCPL-7720 and HCPL-7720-000E maintain identical propagation delay (40ns maximum for both tpLH and tpHL) and rise/fall times (9ns and 8ns typical).

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in high-speed digital isolation circuits?

A: Yes. Both parts support the same 25MBd data rate, 10kV/µs common mode transient immunity, and 3750Vrms isolation voltage, making them functionally interchangeable for high-speed isolation applications.
