HCPL-260L-020 Equivalent & Substitute Parts

Part Overview

The HCPL-260L-020 is a logic output optoisolator manufactured by Broadcom Limited, featuring 5000Vrms isolation voltage, open collector Schottky clamped output, and 15MBd data rate in an 8-DIP through-hole package. This part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. Substitute parts must maintain compatibility across isolation voltage, output type, channel configuration, and package form factor while accommodating variations in data rate, common mode transient immunity, and supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Single channel configuration (1 input, 0 side 2 inputs)
• Open collector output type with Schottky clamping
• 8-DIP through-hole package (0.300", 7.62mm)
• 50 mA output current per channel
• DC input type

Secondary Compatibility Criteria:

• Isolation voltage: 5000Vrms (primary) or 2500Vrms (acceptable with application review)
• Common mode transient immunity: 10kV/µs or higher
• Data rate: 10MBd or higher
• Supply voltage: 4.5V ~ 5.5V (core requirement) or extended range including 2.7V ~ 3.6V
• Operating temperature: -40°C ~ 85°C or 0°C ~ 70°C

Direct Equivalent (Identical Specifications):

• HCPL-260L-020E: Active product, Broadcom Limited, identical electrical and mechanical specifications, RoHS3 compliant, tube packaging

Functional Equivalents (Reduced Isolation Voltage):

• FOD260L: Fairchild Semiconductor, 5000Vrms isolation, 25kV/µs CMTI, 10Mbps data rate, active status
• 6N137F: Toshiba Semiconductor, 2500Vrms isolation, 200V/µs CMTI, 10MBd data rate, active status
• HCPL2611: onsemi, 2500Vrms isolation, 10kV/µs CMTI, 10Mbps data rate, obsolete status
• HCPL2601: onsemi, 2500Vrms isolation, 5kV/µs CMTI, 10Mbps data rate, obsolete status
• TLP2601(F): Toshiba Semiconductor, 2500Vrms isolation, 1kV/µs CMTI, 10MBd data rate, 25 mA output, active status

Package Variants (Surface Mount):

• TLP2601(LF1,F): Toshiba Semiconductor, 8-SMD gull wing, 2500Vrms isolation, 1kV/µs CMTI, 25 mA output, active status
• TLP2601(TP1,F): Toshiba Semiconductor, 8-SMD gull wing, 2500Vrms isolation, 1kV/µs CMTI, 25 mA output, active status

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Recommended): HCPL-260L-020E is the primary substitute, offering identical electrical and mechanical specifications with active product status and RoHS3 compliance. This part maintains full compatibility with existing designs without modification.

Tier 2 - High-Performance Equivalent: FOD260L provides 5000Vrms isolation matching the original part, with superior common mode transient immunity (25kV/µs) and active product status. This part is suitable for applications requiring maximum noise immunity and is RoHS compliant.

Tier 3 - Functional Equivalents (Reduced Isolation): For applications where 2500Vrms isolation is acceptable, TLP2601(F) offers active status and RoHS compliance. Note the reduced output current (25 mA versus 50 mA) and lower common mode transient immunity (1kV/µs). 6N137F provides active status but operates within a narrower temperature range (0°C ~ 70°C). HCPL2611 and HCPL2601 are obsolete and should be avoided for new designs.

Tier 4 - Surface Mount Variants: TLP2601(LF1,F) and TLP2601(TP1,F) provide surface mount alternatives with identical electrical specifications to TLP2601(F), suitable for PCB redesigns requiring SMD assembly.

Frequently Asked Questions (FAQ)

Q: Can HCPL-260L-020E be used as a direct drop-in replacement for HCPL-260L-020? A: Yes. HCPL-260L-020E maintains identical electrical specifications, channel configuration, output type, and 8-DIP package form factor. The primary difference is active product status and RoHS3 compliance versus the discontinued original part.

Q: What is the key difference between FOD260L and the original HCPL-260L-020? A: Both maintain 5000Vrms isolation and 50 mA output current. FOD260L provides superior common mode transient immunity (25kV/µs versus 10kV/µs) and operates across a wider supply voltage range (3V ~ 5.5V). Data rate is reduced from 15MBd to 10Mbps.

Q: Can I use TLP2601(F) as a substitute if my application requires 5000Vrms isolation? A: No. TLP2601(F) provides only 2500Vrms isolation. Use FOD260L or HCPL-260L-020E for applications requiring 5000Vrms isolation.

Q: What is the impact of using a substitute with lower common mode transient immunity? A: Lower CMTI specifications indicate reduced immunity to high-speed voltage transients on the isolation barrier. Applications with high dV/dt switching events may experience increased propagation delay variation or logic errors. Verify application requirements before substitution.

Q: Are HCPL2611 and HCPL2601 suitable for new designs? A: No. Both parts are obsolete. Use active alternatives: HCPL-260L-020E for 5000Vrms isolation, or TLP2601(F) for 2500Vrms isolation applications.

Q: Can I use surface mount variants TLP2601(LF1,F) or TLP2601(TP1,F) in a through-hole design? A: No. These parts require surface mount assembly on 8-SMD gull wing footprints. They are not compatible with through-hole DIP sockets. Retain through-hole package variants for existing designs.

Q: What is the significance of the reduced output current in TLP2601(F) (25 mA versus 50 mA)? A: Lower output current limits the maximum load current that can be driven by the optoisolator output. Verify that downstream logic or load circuits can operate within the 25 mA specification before substitution.

Q: Does HCPL-260L-020E require any design modifications compared to the original part? A: No design modifications are required. HCPL-260L-020E is a direct equivalent with identical pinout, electrical characteristics, and package dimensions.
