HCPL-260L Equivalent & Substitute Parts

Part Overview

The HCPL-260L is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 8-DIP through-hole component provides 3750Vrms isolation with open collector Schottky clamped output, supporting data rates up to 15MBd and common mode transient immunity of 10kV/µs. The part is currently active in production. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-260L is determined by the following critical parameters:

• Package compatibility: 8-DIP (0.300", 7.62mm) through-hole mounting
• Channel configuration: Single channel (1/0 input/output)
• Output architecture: Open collector with Schottky clamping
• Input type: DC
• Output current capability: 50 mA per channel minimum
• Operating temperature range: -40°C ~ 85°C
• Supply voltage compatibility: Overlap with 4.5V ~ 5.5V range

Substitute parts must maintain these core electrical and mechanical characteristics. Variations in isolation voltage, CMTI rating, data rate, and propagation delay are permitted within the scope of application requirements, provided the substitute meets or exceeds the minimum performance thresholds of the primary application.

Parameter Comparison

Engineering Selection Recommendations

FOD260L (Fairchild Semiconductor): This substitute offers enhanced isolation voltage (5000Vrms) and superior common mode transient immunity (25kV/µs) compared to the HCPL-260L. The FOD260L maintains identical output current capability and package form factor. Data rate is reduced to 10Mbps, which may impact applications requiring the full 15MBd bandwidth of the primary part. The FOD260L is suitable for applications where higher isolation margins and faster transient response are beneficial.

HCPL2601 (onsemi): This part is obsolete and carries ROHS3 compliance certification. Isolation voltage is reduced to 2500Vrms with common mode transient immunity of 5kV/µs. Propagation delay and rise/fall times are comparable to the primary part. The HCPL2601 is electrically compatible for applications with lower isolation requirements but should be selected only when inventory of active parts is unavailable.

HCPL2611 (onsemi): This part is obsolete and ROHS3 compliant. It provides 2500Vrms isolation with 10kV/µs common mode transient immunity, matching the CMTI specification of the HCPL-260L. Data rate and propagation delay are equivalent to the primary part. The HCPL2611 is suitable as a substitute when isolation voltage requirements permit operation at 2500Vrms and active inventory is constrained.

Frequently Asked Questions (FAQ)

Q: Can FOD260L replace HCPL-260L in all applications?

A: FOD260L is mechanically and functionally compatible in 8-DIP through-hole applications. The reduced data rate (10Mbps vs. 15MBd) must be evaluated against application bandwidth requirements. The enhanced isolation voltage and CMTI rating provide additional performance margin in high-noise environments.

Q: Why are HCPL2601 and HCPL2611 marked as obsolete?

A: Product status reflects manufacturer lifecycle designation. Obsolete parts may have limited availability but remain functionally valid for applications within their electrical specifications. Inventory levels should be verified before design selection.

Q: What is the key difference between HCPL2601 and HCPL2611?

A: Both parts are identical except for common mode transient immunity: HCPL2601 provides 5kV/µs while HCPL2611 provides 10kV/µs. Selection depends on application transient immunity requirements.

Q: Are the onsemi parts RoHS compliant?

A: HCPL2601 and HCPL2611 are ROHS3 compliant. The HCPL-260L is RoHS non-compliant. This distinction may affect procurement and regulatory requirements.

Q: Can these parts be used interchangeably in PCB designs?

A: All substitute parts share identical 8-DIP package dimensions and through-hole pin configuration. PCB layouts are directly compatible. Electrical parameter differences must be validated against circuit design specifications.

Q: What supply voltage range is common to all parts?

A: The 4.5V ~ 5.5V range is supported by all four parts. The HCPL-260L additionally supports 2.7V ~ 3.6V operation, which is not available in the substitute options.
