HCPL0500R1 Equivalent & Substitute Parts

Part Overview

The HCPL0500R1 is a single-channel optoisolator with transistor output and base connection, manufactured by onsemi. This component provides 2500Vrms isolation and operates across the industrial temperature range of -40°C to 85°C in an 8-SOIC surface mount package. The part is currently listed as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the HCPL0500R1 is determined by the following critical parameters: single-channel configuration, isolation voltage rating, current transfer ratio range, switching speed characteristics, transistor output with base connection, maximum output voltage and current ratings, forward voltage specifications, operating temperature range, and 8-SOIC package compatibility.

The substitute parts are grouped into two categories:

Parametric Equivalents (HCPL0500R2, HCPL0500R2V): These parts maintain identical electrical specifications across all key parameters including 2500Vrms isolation, 7-50% current transfer ratio, 450ns/500ns switching times, and -40°C to 85°C operating range. Both are manufactured by Fairchild Semiconductor and are in active product status.

Direct Manufacturer Equivalent (HCPL-0500-000E): This Broadcom Limited part shares the same functional architecture and package but operates at an elevated isolation voltage of 3750Vrms with modified switching characteristics (200ns/1.3µs) and an extended temperature range of -55°C to 100°C. This part is functionally compatible for applications where the HCPL0500R1 specifications are met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete HCPL0500R1, the HCPL0500R2 and HCPL0500R2V are the primary candidates. Both parts are manufactured by Fairchild Semiconductor and maintain active product status with identical electrical and thermal specifications. These parts are suitable for applications requiring exact parameter matching and are available in higher inventory quantities.

The HCPL-0500-000E from Broadcom Limited is a functional equivalent suitable for applications where enhanced isolation voltage (3750Vrms versus 2500Vrms) and extended operating temperature range (-55°C to 100°C versus -40°C to 85°C) provide design margin or are required by system specifications. This part carries RoHS3 compliance certification. The HCPL-0500-000E exhibits different switching characteristics with faster turn-on time (200ns versus 450ns) and slower turn-off time (1.3µs versus 500ns), which may require circuit timing evaluation in speed-critical applications.

All substitute parts maintain the same 8-SOIC package footprint, single-channel architecture, transistor output configuration with base connection, and maximum output ratings, ensuring mechanical and functional compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can HCPL0500R2 and HCPL0500R2V be used interchangeably with HCPL0500R1?

A: Yes. Both parts are parametric equivalents with identical isolation voltage (2500Vrms), current transfer ratio range (7-50% @ 16mA), switching times (450ns/500ns), output voltage and current ratings, and operating temperature range (-40°C to 85°C). The 8-SOIC package dimensions are identical, enabling direct PCB substitution.

Q: What are the key differences between HCPL0500R2/R2V and HCPL-0500-000E?

A: The HCPL-0500-000E provides higher isolation voltage (3750Vrms versus 2500Vrms) and extended temperature range (-55°C to 100°C versus -40°C to 85°C). However, switching characteristics differ: turn-on time is faster (200ns versus 450ns) while turn-off time is slower (1.3µs versus 500ns). The minimum current transfer ratio is lower (5% versus 7%). These differences require circuit timing analysis for applications sensitive to switching speed.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts are supplied in 8-SOIC surface mount packages with identical footprint dimensions (0.154", 3.90mm width). Packaging formats differ by supplier: HCPL0500R2 and HCPL0500R2V are supplied in bulk, while HCPL-0500-000E is supplied in tube format.

Q: Which substitute part should be selected for new designs?

A: For new designs, HCPL0500R2V is recommended due to active product status, high inventory availability (3235 pcs), and identical electrical specifications to the original HCPL0500R1. The HCPL-0500-000E is suitable when enhanced isolation voltage or extended temperature range provides system-level benefits.

Q: Are there compliance or certification differences between substitute parts?

A: The HCPL-0500-000E carries RoHS3 compliance certification. All parts are REACH unaffected and classified under ECCN EAR99 with HTSUS code 8541.49.8000. Moisture sensitivity level is 1 (unlimited) for HCPL0500R1 and HCPL-0500-000E; MSL status is not specified for Fairchild parts.
