Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-7611#300 is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 3750Vrms
• Single channel configuration
• Open collector Schottky clamped output topology
• Data rate capability: 10MBd minimum
• Common mode transient immunity: 10kV/µs minimum
• Output current capability: 50 mA per channel
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-SMD, Gull Wing

The HCPL-2601#300 meets all specified electrical and mechanical parameters and qualifies as a direct substitute. The primary distinction is product status: HCPL-2601#300 maintains active production status, whereas HCPL-7611#300 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2601#300 is the direct substitute for the obsolete HCPL-7611#300. Both components share identical electrical specifications, isolation ratings, output characteristics, and package configurations. The HCPL-2601#300 is currently in active production status, ensuring long-term availability and supply chain continuity.

Both components carry identical RoHS non-compliance status, REACH unaffected designation, and EAR99 export classification. Moisture sensitivity level and handling requirements are equivalent between the two parts.

Selection of the HCPL-2601#300 eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs utilizing the HCPL-7611#300.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-2601#300 be used as a direct replacement for the HCPL-7611#300 in existing designs?

A: Yes. The HCPL-2601#300 meets all electrical and mechanical specifications of the HCPL-7611#300, including isolation voltage, data rate, output current, supply voltage range, operating temperature, and package type. No design modifications are required.

Q: What is the primary difference between these two parts?

A: The HCPL-7611#300 is obsolete, while the HCPL-2601#300 maintains active production status. All functional and electrical parameters are identical.

Q: Are there any timing differences between the HCPL-7611#300 and HCPL-2601#300?

A: Propagation delay specifications differ slightly. The HCPL-7611#300 specifies maximum propagation delays of 75ns for both tpLH and tpHL, while the HCPL-2601#300 specifies 100ns for both parameters. Rise and fall times remain identical at 24ns and 10ns respectively. These differences fall within acceptable margins for most applications operating at 10MBd data rates.

Q: Are both parts available in the same packaging?

A: Yes. Both the HCPL-7611#300 and HCPL-2601#300 are supplied in 8-SMD, Gull Wing surface mount packages with identical pin configurations and mechanical dimensions.

Q: Do compliance and certification requirements differ between these parts?

A: No. Both components share identical RoHS non-compliance status, REACH unaffected designation, EAR99 export classification, and MSL 1 moisture sensitivity level.
