HCPL-0201-000E Equivalent & Substitute Parts

Part Overview

The HCPL-0201-000E is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 3.75kVrms push-pull optoisolator operates at 5MBd data rate with 8-SO Tall packaging and is currently in active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, particularly when addressing packaging preferences, supply voltage ranges, or common mode transient immunity specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-0201-000E are grouped based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Voltage isolation rating (3750Vrms minimum)
• Output configuration (Push-Pull, Totem Pole)
• Data rate (5MBd)
• Single channel configuration
• Surface mount technology
• Input type (DC)

Secondary Variation Parameters:

• Common Mode Transient Immunity (CMTI): Ranges from 1kV/µs to 25kV/µs across substitute options
• Output current capability: 10 mA to 25 mA
• Supply voltage range: 2.7V ~ 5.5V or 4.5V ~ 20V
• Operating temperature range: -40°C ~ 85°C or -40°C ~ 105°C
• Package format: 8-SO Tall or 5-SO
• RoHS compliance status: ROHS3 Compliant or non-compliant

Substitutes maintain core isolation and switching characteristics while offering variations in performance envelope and packaging options.

Parameter Comparison

Engineering Selection Recommendations

ACPL-021L-000E is suitable for applications requiring enhanced common mode transient immunity (25kV/µs) and extended operating temperature range (-40°C ~ 105°C). This part maintains 3750Vrms isolation and 5MBd data rate. The reduced output current (10 mA versus 25 mA) and narrower supply voltage range (2.7V ~ 5.5V) must be evaluated against circuit requirements. ROHS3 compliance is maintained.

ACPL-M21L-000E provides identical electrical performance to ACPL-021L-000E with alternative 5-SO packaging (6-SOIC, 4.40mm width, 5 leads). This package variant is applicable when board layout or connector constraints require reduced package footprint. ROHS3 compliance is maintained.

HCPL-0201 is electrically equivalent to HCPL-0201-000E with identical 8-SO Tall packaging and electrical specifications. This part differs in RoHS compliance status (non-compliant) and reduced common mode transient immunity (1kV/µs). Selection is appropriate only when RoHS non-compliance is acceptable and lower CMTI performance is sufficient.

HCPL-0201#500 is functionally identical to HCPL-0201 with Tape & Reel packaging instead of Tube. This variant is suitable for high-volume automated assembly processes. RoHS non-compliance and 1kV/µs CMTI apply identically to HCPL-0201.

Frequently Asked Questions (FAQ)

Q: Can ACPL-021L-000E directly replace HCPL-0201-000E in existing designs?

A: Direct replacement requires verification of output current requirements. ACPL-021L-000E provides 10 mA output current versus 25 mA in HCPL-0201-000E. If the circuit requires the full 25 mA output capability, ACPL-021L-000E is not suitable. Supply voltage range differs (2.7V ~ 5.5V versus 4.5V ~ 20V), requiring circuit validation.

Q: What is the primary difference between ACPL-021L-000E and ACPL-M21L-000E?

A: Both parts are electrically identical with 25kV/µs CMTI, 10 mA output current, and -40°C ~ 105°C operating range. The difference is packaging: ACPL-021L-000E uses 8-SO Tall (0.154" width), while ACPL-M21L-000E uses 5-SO (0.173" width, 5 leads). Package selection depends on PCB layout constraints and connector compatibility.

Q: Is HCPL-0201 a suitable substitute for HCPL-0201-000E?

A: HCPL-0201 maintains identical electrical performance and 8-SO Tall packaging. However, it is RoHS non-compliant and provides only 1kV/µs CMTI compared to 5kV/µs and 10kV/µs in HCPL-0201-000E. Selection is appropriate only when RoHS compliance is not required and lower CMTI performance is acceptable.

Q: When should HCPL-0201#500 be selected over HCPL-0201?

A: HCPL-0201#500 is functionally identical to HCPL-0201 with Tape & Reel packaging. Selection depends on assembly process requirements. Tape & Reel format is standard for automated pick-and-place assembly, while Tube packaging is typical for manual or lower-volume assembly.

Q: Do all substitute parts maintain the same isolation voltage rating?

A: Yes. All substitute parts listed maintain 3750Vrms isolation voltage, which is the core isolation specification for this product category.

Q: What is the impact of different CMTI ratings on circuit performance?

A: Common Mode Transient Immunity (CMTI) specifies the maximum rate of voltage change the optoisolator can tolerate without false triggering. Higher CMTI (25kV/µs in ACPL series) provides better noise immunity in high-speed switching environments. Lower CMTI (1kV/µs in HCPL-0201) is suitable for lower-speed or less noisy applications.
