HCPL-2530#320 Equivalent & Substitute Parts

Part Overview

The HCPL-2530#320 is a 2-channel optoisolator with transistor output manufactured by Broadcom Limited, rated for 5000Vrms isolation voltage. This component is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production requirements. The part operates across a temperature range of -55°C to 100°C and is packaged in 8-SMD, Gull Wing configuration suitable for surface mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-2530#320 is determined by the following critical parameters: number of channels (2), output type (transistor), mounting configuration (8-SMD, Gull Wing surface mount), input type (DC), maximum output voltage (20V), output current per channel (8mA), operating temperature range (-55°C to 100°C), and forward voltage characteristics.

The substitute parts are grouped into two categories based on isolation voltage rating:

Direct Equivalent (5000Vrms Isolation): HCPL-2530-320E maintains identical electrical specifications and isolation voltage, differing only in product status and RoHS compliance.

Functional Substitutes (2500Vrms Isolation): HCPL2530S and HCPL2530SD provide equivalent channel count, output type, and package configuration but operate at reduced isolation voltage (2500Vrms). These parts are suitable for applications where 2500Vrms isolation meets design requirements.

Parameter Comparison

Engineering Selection Recommendations

HCPL-2530-320E is the primary direct equivalent for HCPL-2530#320. It maintains all electrical specifications including 5000Vrms isolation voltage and identical switching characteristics. This part is currently active in production and ROHS3 compliant, addressing both availability and regulatory compliance concerns of the discontinued original part.

HCPL2530SD (Fairchild Semiconductor) is the recommended substitute when isolation voltage requirements permit 2500Vrms operation. This part is active in production with the highest inventory availability (50,682 pcs) and provides identical channel count, output type, and package configuration. The reduced isolation voltage and increased switching time (450ns/500ns versus 200ns/1.3µs) must be evaluated against specific application requirements.

HCPL2530S (onsemi) is an alternative 2500Vrms substitute with identical electrical characteristics to HCPL2530SD but carries obsolete product status, making it unsuitable for new designs requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2530-320E be used as a direct replacement for HCPL-2530#320?

A: Yes. HCPL-2530-320E is electrically and mechanically identical to HCPL-2530#320, with matching 5000Vrms isolation voltage, 2-channel configuration, 8-SMD Gull Wing package, and all switching characteristics. The primary differences are product status (active versus discontinued) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What is the key difference between HCPL-2530-320E and HCPL2530SD?

A: The primary difference is isolation voltage rating. HCPL-2530-320E maintains 5000Vrms isolation identical to the original part, while HCPL2530SD operates at 2500Vrms. Additionally, HCPL2530SD has slower switching times (450ns/500ns turn-on/turn-off versus 200ns/1.3µs). Both share identical channel count, output type, package, and operating temperature range.

Q: Can I substitute a 2500Vrms part for a 5000Vrms requirement?

A: Substitution of 2500Vrms parts (HCPL2530S or HCPL2530SD) for 5000Vrms applications is not permissible. Isolation voltage is a critical safety and functional parameter. Use only if your application design specifies 2500Vrms isolation as acceptable.

Q: Are all substitute parts available in the same package?

A: Yes. All listed parts use 8-SMD, Gull Wing surface mount packaging, ensuring mechanical compatibility on PCB layouts designed for HCPL-2530#320.

Q: Which substitute part has the best availability?

A: HCPL2530SD (Fairchild Semiconductor) has the highest inventory availability at 50,682 pcs. However, availability should be verified with your component supplier, as inventory levels change continuously.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is a regulatory requirement in many markets and for certain customer specifications. HCPL-2530-320E is ROHS3 compliant, while the original HCPL-2530#320 is non-compliant. Verify your application's regulatory requirements before component selection.
