HCPL0452V Equivalent & Substitute Parts

Part Overview

The HCPL0452V is a single-channel optoisolator with transistor output manufactured by onsemi, designed for galvanic isolation applications requiring 2500Vrms isolation voltage. The device features DC input, transistor output configuration, and is housed in an 8-SOIC surface mount package. The HCPL0452V is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL0452V is determined by the following critical parameters:

• Single-channel configuration: Substitute must provide exactly 1 isolated channel
• Transistor output topology: Output stage must be transistor-based, not TRIAC or other types
• DC input type: Input must accept DC signaling
• Package compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Isolation voltage: Minimum 2500Vrms isolation rating
• Output current capability: Minimum 8mA per channel
• Maximum output voltage: 20V rating
• Forward voltage and current: Input LED specifications (Vf ≤ 1.5V, If ≤ 25mA)
• Operating temperature range: Must support -40°C to 85°C minimum

The HCPL-0452-000E by Broadcom Limited meets all substitution criteria while offering enhanced isolation voltage (3750Vrms) and extended operating temperature range (-55°C to 100°C).

Parameter Comparison

Engineering Selection Recommendations

The HCPL-0452-000E is the direct substitute for the obsolete HCPL0452V. Both devices share identical package geometry, channel count, output topology, and primary electrical specifications. The Broadcom part offers superior isolation voltage (3750Vrms versus 2500Vrms) and extended operating temperature range (-55°C to 100°C versus -40°C to 85°C), providing enhanced design margin without functional compromise.

The HCPL-0452-000E carries Active product status and RoHS3 compliance, ensuring long-term availability and regulatory alignment. Both parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification. The substitute part is suitable for direct replacement in existing HCPL0452V designs without PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-0452-000E replace the HCPL0452V in existing designs?

A: Yes. Both devices are housed in identical 8-SOIC packages with matching pinouts, isolation voltage ratings meeting or exceeding 2500Vrms, and equivalent output current specifications (8mA per channel). Direct PCB substitution is possible without layout changes.

Q: What are the key differences between these parts?

A: The HCPL-0452-000E provides higher isolation voltage (3750Vrms versus 2500Vrms), extended operating temperature range (-55°C to 100°C versus -40°C to 85°C), and Active product status versus Obsolete. Turn-on/turn-off timing is slightly slower on the Broadcom part (1µs maximum versus 450ns/300ns typical on onsemi).

Q: Are there any compliance or regulatory differences?

A: Both parts are REACH Unaffected and maintain MSL 1 (Unlimited) classification. The HCPL-0452-000E additionally carries RoHS3 compliance certification, supporting modern regulatory requirements.

Q: Does the package remain the same?

A: Yes. Both parts use 8-SOIC surface mount packaging with 0.154" (3.90mm) width. Pin spacing and footprint are identical, enabling direct substitution on existing PCBs.

Q: What is the minimum current transfer ratio for the substitute?

A: The HCPL-0452-000E specifies 15% minimum current transfer ratio at 16mA input, compared to 19% for the HCPL0452V. Both values support standard optoisolator circuit designs with appropriate input current levels.
