Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-7601#300 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms
• Common mode transient immunity: 1kV/µs minimum
• Output configuration: Open Collector, Schottky Clamped
• Number of channels: 1
• Input type: DC
• Data rate: 10MBd
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-SMD, Gull Wing

The HCPL-261A#300 meets all these criteria and is classified as an active product, making it the direct functional equivalent for the obsolete HCPL-7601#300.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-261A#300 is the direct substitute for the obsolete HCPL-7601#300. Both components share identical electrical specifications for isolation voltage, CMTI, output configuration, data rate, and supply voltage requirements. The HCPL-261A#300 is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts carry identical compliance certifications: RoHS non-compliant, REACH Unaffected, and ECCN EAR99 classification. Moisture sensitivity level is equivalent at MSL 1 (Unlimited).

Minor timing parameter variations exist between the two parts. The HCPL-261A#300 exhibits slightly higher propagation delay (100ns maximum versus 75ns) and slower rise/fall times (42ns/12ns typical versus 24ns/10ns). Forward voltage is lower (1.3V typical versus 1.5V) and maximum forward current is reduced (10mA versus 20mA). These differences remain within the functional envelope for standard digital isolation applications operating at 10MBd.

Frequently Asked Questions (FAQ)

Q: Can HCPL-261A#300 directly replace HCPL-7601#300 in existing designs?

A: Yes. Both components meet identical isolation voltage (3750Vrms), CMTI (1kV/µs), output type (Open Collector, Schottky Clamped), and data rate (10MBd) specifications. Package configuration and pinout are identical (8-SMD, Gull Wing). No circuit modifications are required.

Q: What are the timing differences between these parts?

A: The HCPL-261A#300 has maximum propagation delay of 100ns compared to 75ns for the HCPL-7601#300. Rise and fall times are also slightly slower. These differences do not affect functionality in applications operating at 10MBd data rates.

Q: Are there supply chain advantages to using HCPL-261A#300?

A: Yes. The HCPL-261A#300 is classified as an active product with current manufacturing support, whereas the HCPL-7601#300 is obsolete. This ensures consistent availability and eliminates end-of-life supply risks.

Q: Do both parts have the same compliance certifications?

A: Yes. Both components are RoHS non-compliant, REACH Unaffected, and classified as ECCN EAR99. Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: Are there any electrical parameter differences that affect circuit design?

A: Forward voltage is slightly lower on the HCPL-261A#300 (1.3V typical versus 1.5V), and maximum forward current is reduced (10mA versus 20mA). These differences are within normal component tolerance ranges and do not require design changes for standard applications.
