HCPL-2411#300 Equivalent & Substitute Parts

Part Overview

The HCPL-2411#300 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications requiring 2500Vrms isolation voltage. This component integrates a single-channel optoisolator with tri-state output capability, supporting data rates up to 40MBd and common mode transient immunity of 1kV/µs. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-2411#300 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 2500Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Tri-State (mandatory match)
• Data Rate: 40MBd (mandatory match)
• Common Mode Transient Immunity: 1kV/µs minimum (mandatory match)
• Current - Output / Channel: 25 mA (mandatory match)
• Input Type: DC (mandatory match)
• Voltage - Supply: 4.75V ~ 5.25V (mandatory match)
• Operating Temperature Range: 0°C ~ 70°C (mandatory match)

The HCPL-2411-000E qualifies as a direct substitute based on identical electrical and functional specifications. Differences in packaging format (Surface Mount Gull Wing versus Through Hole DIP) and product status do not affect functional equivalence in isolation performance or signal integrity.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2411-000E is the direct functional equivalent for the discontinued HCPL-2411#300. Selection between these parts depends on design constraints:

HCPL-2411-000E is the preferred choice for new designs and ongoing production due to its active product status and ROHS3 compliance. This part maintains identical electrical performance and isolation specifications while offering improved environmental and regulatory compliance.

HCPL-2411#300 remains suitable for legacy system maintenance only where existing surface-mount gull-wing packaging is required and RoHS non-compliance is acceptable. Given its discontinued status, sourcing is limited to remaining inventory.

The packaging difference (surface-mount gull wing versus through-hole DIP) represents the primary design consideration. PCB layout and assembly process compatibility must be evaluated based on specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2411-000E directly replace HCPL-2411#300 in existing designs?

A: Electrical and functional replacement is complete. The HCPL-2411-000E provides identical isolation voltage, data rate, output type, and timing specifications. PCB layout modification is required due to packaging format differences (through-hole DIP versus surface-mount gull wing).

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

A: The HCPL-2411#300 uses surface-mount gull-wing packaging, while the HCPL-2411-000E uses through-hole 8-DIP packaging. Both parts are manufactured by Broadcom Limited and share identical electrical specifications.

Q: Why is HCPL-2411#300 discontinued?

A: The part is discontinued at DiGi Electronics. The HCPL-2411-000E remains in active production as the current offering from Broadcom Limited.

Q: Does RoHS compliance affect functional performance?

A: RoHS compliance status does not affect electrical performance or isolation capability. The HCPL-2411-000E's ROHS3 compliance reflects manufacturing process improvements and environmental standards adherence, with no impact on signal integrity or isolation specifications.

Q: Are there any timing or performance differences between these parts?

A: No. Propagation delay, rise time, fall time, and all other timing parameters are identical between HCPL-2411#300 and HCPL-2411-000E.

Q: What inventory status should be considered for procurement?

A: HCPL-2411#300 has 1185 pieces available as new original stock. HCPL-2411-000E has 857 pieces available as new original stock. Given the discontinued status of HCPL-2411#300, HCPL-2411-000E is recommended for new procurement.
