HCPL-2530#300 Equivalent & Substitute Parts

Part Overview

The HCPL-2530#300 is a 2-channel optoisolator with transistor output manufactured by Broadcom Limited, rated for 3750Vrms isolation voltage. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production needs. Substitute parts must maintain compatibility across electrical performance, package configuration, and thermal operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-2530#300 is determined by the following critical parameters:

• Number of Channels: Must be 2
• Output Type: Must be Transistor
• Mounting Type: Must be Surface Mount
• Package / Case: Must be 8-SMD, Gull Wing
• Operating Temperature Range: Must support -55°C ~ 100°C
• Voltage - Isolation: Minimum 3750Vrms (equal or greater)
• Current Transfer Ratio: Must support 7% minimum @ 16mA
• Current - Output / Channel: Must support 8mA minimum
• Voltage - Output (Max): Must support 20V minimum

Substitute parts are grouped based on isolation voltage rating and manufacturer compliance status. Parts meeting all electrical and mechanical parameters are considered direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

HCPL-2530-300E is the primary direct equivalent. This Broadcom Limited part maintains identical electrical specifications including 3750Vrms isolation voltage, 200ns/1.3µs switching times, and all output characteristics. The part is currently active in production and ROHS3 compliant, addressing regulatory requirements where applicable.

HCPL2530S and HCPL2530SD are functional alternatives with reduced isolation voltage (2500Vrms). These parts meet all other electrical and mechanical requirements but operate at lower isolation ratings. Selection of these alternatives is appropriate only when circuit design permits operation at 2500Vrms isolation. HCPL2530SD is currently active; HCPL2530S is obsolete.

For applications requiring maintained isolation voltage specification of 3750Vrms, HCPL-2530-300E is the recommended selection. For applications where 2500Vrms isolation is acceptable, HCPL2530SD provides active production status and higher inventory availability.

Frequently Asked Questions (FAQ)

Q: Can HCPL2530S or HCPL2530SD be used as direct replacements for HCPL-2530#300?

A: These parts are functionally compatible in applications where 2500Vrms isolation voltage is acceptable. The reduced isolation rating is the only electrical difference. All other parameters including channel count, output type, switching times, and package configuration are equivalent. Circuit design must accommodate the lower isolation specification.

Q: What is the primary difference between HCPL-2530-300E and the original HCPL-2530#300?

A: HCPL-2530-300E is electrically and mechanically identical to HCPL-2530#300. The primary difference is product status: HCPL-2530-300E is active in production while HCPL-2530#300 is discontinued. HCPL-2530-300E also carries ROHS3 compliance certification.

Q: Are all substitute parts available in the same 8-SMD, Gull Wing package?

A: Yes. All listed substitute parts use identical 8-SMD, Gull Wing surface mount packaging, ensuring PCB layout and assembly compatibility without modification.

Q: Do switching time differences between HCPL-2530-300E and HCPL2530S/HCPL2530SD affect circuit performance?

A: HCPL-2530-300E specifies 200ns turn-on and 1.3µs turn-off times. HCPL2530S and HCPL2530SD specify 450ns turn-on and 500ns turn-off times. Circuit designs dependent on faster switching characteristics must use HCPL-2530-300E. Applications with relaxed timing requirements can accommodate the slower switching alternatives.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across -55°C to 100°C, matching the original HCPL-2530#300 specification.
