Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-260L-020E is determined by the following critical parameters:

Isolation Voltage: Minimum 5000Vrms required
Output Configuration: Open collector with Schottky clamping
Package Type: 8-DIP (0.300", 7.62mm) through-hole mounting
Number of Channels: Single channel (1)
Input Type: DC
Output Current: 50 mA per channel
Operating Temperature Range: -40°C to 85°C
Supply Voltage Compatibility: Overlap with 4.5V ~ 5.5V range

The FOD260L meets all critical substitution criteria with enhanced CMTI performance. The HCPL2601 and HCPL2611 share package and channel configuration but operate at reduced isolation voltage (2500Vrms) and lower data rates (10Mbps), making them suitable only for applications with lower isolation requirements.

Engineering Selection Recommendations

Primary Substitute: FOD260L

The FOD260L from Fairchild Semiconductor is the direct functional equivalent for the HCPL-260L-020E. Both devices maintain 5000Vrms isolation voltage, open collector Schottky clamped output, 50 mA output current, and identical 8-DIP package configuration. The FOD260L provides superior common mode transient immunity at 25kV/µs compared to the HCPL-260L-020E at 10kV/µs. Both parts operate across the -40°C to 85°C temperature range. The FOD260L is actively produced and available in bulk packaging.

Secondary Substitutes: HCPL2601 and HCPL2611

The HCPL2601 and HCPL2611 from onsemi are functionally compatible in package and channel configuration but operate at reduced isolation voltage (2500Vrms versus 5000Vrms). These parts are classified as obsolete products. Selection of these alternatives is appropriate only for applications where 2500Vrms isolation meets system requirements. The HCPL2611 matches the HCPL-260L-020E CMTI specification at 10kV/µs, while the HCPL2601 operates at 5kV/µs CMTI.

Frequently Asked Questions (FAQ)

Q: Can FOD260L directly replace HCPL-260L-020E in existing designs?

A: Yes. Both devices share identical isolation voltage (5000Vrms), output configuration (open collector with Schottky clamping), output current rating (50 mA), and 8-DIP package footprint. The FOD260L provides enhanced CMTI performance at 25kV/µs. Pin-for-pin compatibility exists for standard optoisolator applications.

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

A: Both parts operate at 2500Vrms isolation voltage and 10Mbps data rate in 8-DIP packages. The primary difference is common mode transient immunity: HCPL2611 specifies 10kV/µs CMTI while HCPL2601 specifies 5kV/µs CMTI. Both are obsolete products from onsemi.

Q: Why are HCPL2601 and HCPL2611 listed as obsolete?

A: Product status reflects manufacturer lifecycle classification. Obsolete parts may have limited availability and no guaranteed future supply. These parts remain functionally suitable for applications with 2500Vrms isolation requirements but should not be selected for new designs requiring long-term component availability.

Q: Is the HCPL-260L-020E compatible with 3.3V supply systems?

A: Yes. The HCPL-260L-020E supports dual supply voltage ranges: 2.7V ~ 3.6V and 4.5V ~ 5.5V. The FOD260L supports 3V ~ 5.5V, providing compatibility with 3.3V systems. The HCPL2601 and HCPL2611 support only 4.5V ~ 5.5V supply range.

Q: What packaging options are available for these optoisolators?

A: All four parts are available in 8-DIP (0.300", 7.62mm) through-hole package configuration. The HCPL-260L-020E is supplied in tube packaging, FOD260L in bulk packaging, and HCPL2601/HCPL2611 in tube packaging.
