FOD060LR1 Equivalent & Substitute Parts

Part Overview

The FOD060LR1 is a logic output optoisolator manufactured by onsemi, featuring 3750Vrms isolation voltage, open collector Schottky clamped output, and 10Mbps data rate in an 8-SOIC package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The FOD060LR1 provides single-channel galvanic isolation suitable for industrial control, power management, and digital signal transmission applications requiring high common mode transient immunity.

Substitute Part Grouping Explanation

Substitute parts for the FOD060LR1 are selected based on strict electrical and mechanical compatibility criteria. The following parameters must match or exceed the original specification:

Isolation voltage: 3750Vrms (exact match required)
Number of channels: 1 (exact match required)
Output configuration: Open collector, Schottky clamped (exact match required)
Data rate: 10MBd minimum (exact match required)
Output current capability: 50 mA minimum (exact match required)
Package type: 8-SOIC form factor (exact match required)
Operating temperature range: -40°C ~ 85°C minimum (exact match required)

The Broadcom Limited HCPL-0600 and HCPL-0601 series meet these core electrical requirements. The primary differentiator among substitute options is common mode transient immunity (CMTI), which varies between 5kV/µs and 10kV/µs depending on the specific part number variant. Secondary considerations include packaging format (tube, cut tape, or tape & reel) and RoHS compliance status.

Engineering Selection Recommendations

For applications requiring direct replacement of the FOD060LR1, the HCPL-0601 series is the primary substitute option. All HCPL-0601 variants (HCPL-0601, HCPL-0601-000E, HCPL-0601-060E, HCPL-0601-500E, HCPL-0601-560E) provide 10kV/µs common mode transient immunity, which approaches the original specification of 25kV/µs more closely than the HCPL-0600 series at 5kV/µs.

For applications with relaxed common mode transient immunity requirements, the HCPL-0600 series offers a lower-cost alternative while maintaining all other core electrical parameters.

Packaging format selection depends on procurement and assembly requirements:

Tube packaging: HCPL-0600, HCPL-0600-000E, HCPL-0601, HCPL-0601-000E, HCPL-0601-060E
Cut Tape & Digi-Reel: HCPL-0600-500E, HCPL-0601-500E
Tape & Reel: HCPL-0600-560E, HCPL-0601-560E

RoHS3 compliance is available in HCPL-0600-000E, HCPL-0600-060E, HCPL-0600-500E, HCPL-0600-560E, HCPL-0601-000E, HCPL-0601-060E, HCPL-0601-500E, and HCPL-0601-560E variants. Non-compliant versions are HCPL-0600 and HCPL-0601 base part numbers.

Frequently Asked Questions (FAQ)

Q: Can HCPL-0600 series parts directly replace FOD060LR1 in all applications?

A: HCPL-0600 series parts meet the core electrical requirements (isolation voltage, output type, data rate, output current, package) but provide 5kV/µs common mode transient immunity compared to the FOD060LR1's 25kV/µs specification. Applications sensitive to high-speed common mode voltage transitions may require HCPL-0601 series instead.

Q: What is the difference between HCPL-0601 and HCPL-0600 series?

A: The primary difference is common mode transient immunity: HCPL-0601 provides 10kV/µs while HCPL-0600 provides 5kV/µs. All other electrical parameters are identical. HCPL-0601 is the closer substitute for FOD060LR1.

Q: Are all HCPL-0600 and HCPL-0601 variants pin-compatible with FOD060LR1?

A: Yes. All variants share the 8-SOIC package with identical pinout and mechanical dimensions (0.154" width, 3.90mm).

Q: What is the difference between packaging options (Tube, Cut Tape, Tape & Reel)?

A: Packaging format affects procurement and assembly handling only. Electrical specifications remain identical. Tube is suitable for manual assembly or small quantities. Cut Tape & Digi-Reel and Tape & Reel formats are optimized for automated pick-and-place assembly.

Q: Which variant should I select for new designs?

A: For new designs, select HCPL-0601-500E or HCPL-0601-560E (both RoHS3 compliant, 10kV/µs CMTI). Choose -500E for cut tape format or -560E for tape & reel format based on assembly requirements.

Q: Is the supply voltage range difference significant?

A: FOD060LR1 supports 3V ~ 5.5V while HCPL-0600/0601 series support 4.5V ~ 5.5V. Applications requiring 3V operation cannot use Broadcom substitutes without additional voltage regulation.
