HCPL-2530#500 Equivalent & Substitute Parts

Part Overview

The HCPL-2530#500 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 support and production requirements. Substitute parts must maintain compatibility across electrical characteristics, channel configuration, and surface mount packaging while accounting for variations in isolation voltage ratings and product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the HCPL-2530#500 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Number of Channels: 2
• Output Type: Transistor
• Mounting Type: Surface Mount
• Package / Case: 8-SMD, Gull Wing
• Current Transfer Ratio Range: 7% to 50% @ 16mA
• Voltage - Output (Max): 20V
• Current - Output / Channel: 8mA
• Operating Temperature Range: -55°C ~ 100°C

Variable Parameters Allowing Substitution:

• Voltage - Isolation: The main part specifies 3750Vrms. Substitute parts with lower isolation voltage (2500Vrms) remain functionally compatible in applications where the lower isolation rating is acceptable.
• Turn On / Turn Off Time: Variations in switching speed (200ns/1.3µs vs. 450ns/500ns) are acceptable provided the application timing requirements are met.
• Voltage - Forward (Vf): Minor variations (1.5V vs. 1.45V) are within acceptable tolerance.
• Product Status and RoHS Compliance: These factors affect procurement and regulatory compliance but do not impact electrical substitutability.

Parameter Comparison

Engineering Selection Recommendations

HCPL-2530-500E (Broadcom Limited): This part is the direct equivalent of HCPL-2530#500, maintaining identical electrical specifications including 3750Vrms isolation voltage and 200ns/1.3µs switching times. The primary advantage is active product status with ROHS3 compliance and higher inventory availability (12590 pcs). Packaging is supplied as Tape & Reel (TR), suitable for automated assembly. This is the preferred substitute for applications requiring the original 3750Vrms isolation specification.

HCPL2530S (onsemi): This part provides functional substitution with reduced isolation voltage (2500Vrms) and slower switching times (450ns/500ns). Product status is obsolete, limiting long-term procurement viability. Selection is appropriate only for applications where 2500Vrms isolation is sufficient and switching speed requirements are not critical. ROHS3 compliance is available.

HCPL2530SD (Fairchild Semiconductor): This part offers functional substitution with 2500Vrms isolation voltage and 450ns/500ns switching times. Product status is active with substantial inventory (50682 pcs) and bulk packaging. RoHS compliance status is not specified. Selection is appropriate for applications tolerating reduced isolation voltage and slower switching response, with the advantage of active availability and high stock levels.

Frequently Asked Questions (FAQ)

Q: Can HCPL2530S or HCPL2530SD be used as direct replacements for HCPL-2530#500?

A: Both parts are functionally compatible in applications where 2500Vrms isolation voltage is acceptable. The primary trade-off is reduced isolation rating and increased switching time (450ns/500ns vs. 200ns/1.3µs). Applications requiring the full 3750Vrms isolation specification must use HCPL-2530-500E.

Q: What is the impact of switching time differences between substitute parts?

A: The HCPL-2530#500 and HCPL-2530-500E feature faster turn-on (200ns) and turn-off (1.3µs) times compared to HCPL2530S and HCPL2530SD (450ns/500ns). Applications with timing-critical signal processing may require the faster switching characteristics. Slower switching parts are suitable for general-purpose isolation applications with relaxed timing requirements.

Q: Are there packaging differences between substitute parts?

A: HCPL-2530-500E is supplied in Tape & Reel (TR) format for automated assembly. HCPL2530S packaging is not specified. HCPL2530SD is supplied in bulk packaging. All parts use identical 8-SMD, Gull Wing surface mount packages and are compatible with standard PCB assembly processes.

Q: What is the significance of RoHS compliance differences?

A: HCPL-2530#500 is RoHS non-compliant. HCPL-2530-500E and HCPL2530S are ROHS3 compliant. HCPL2530SD RoHS status is not specified. For applications subject to RoHS regulatory requirements, HCPL-2530-500E or HCPL2530S are required.

Q: Which substitute part has the best long-term availability?

A: HCPL-2530-500E (Broadcom Limited, active status, 12590 pcs inventory) and HCPL2530SD (Fairchild Semiconductor, active status, 50682 pcs inventory) both have active product status. HCPL2530S is obsolete and not recommended for new designs. HCPL-2530-500E is preferred for maintaining design continuity with the original part specification.
