HCPL-0700#500 Equivalent & Substitute Parts

Part Overview

The HCPL-0700#500 is an optoisolator with Darlington output and base connection, manufactured by Broadcom Limited. This component provides 3750Vrms isolation in a single-channel configuration with 8-SOIC surface mount packaging. The part is currently active in production with 1156 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the allowed parameter range for optoisolator devices in this category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCPL-0700#500 are identified based on the following critical parameters that define functional equivalence:

• Isolation Voltage: Minimum 3750Vrms (equal or higher acceptable)
• Number of Channels: 1 channel required
• Current Transfer Ratio Range: 300% to 2600% @ 1.6mA
• Output Type: Darlington with Base or compatible transistor output with base
• Maximum Output Voltage: 7V or higher
• Maximum Output Current: 60mA or higher per channel
• Package / Case: 8-SOIC form factor
• Mounting Type: Surface Mount
• Input Type: DC

Substitutes are grouped into two categories: parametric equivalents (identical electrical specifications with different packaging or compliance status) and manufacturer-recommended alternatives (functionally compatible with minor parameter variations within acceptable operating ranges).

Parameter Comparison

Engineering Selection Recommendations

HCPL-0700-500E is a parametric equivalent to HCPL-0700#500 with identical electrical specifications and 8-SOIC packaging. The primary distinction is RoHS3 compliance status; HCPL-0700-500E meets ROHS3 requirements while HCPL-0700#500 is RoHS non-compliant. Both parts are manufactured by Broadcom Limited and maintain the same isolation voltage, current transfer ratio range, and output characteristics. Selection between these two should be based on regulatory and procurement requirements for RoHS compliance.

SFH6318T is a manufacturer-recommended alternative produced by Vishay Semiconductor Opto Division. This part meets all critical substitution parameters with the following distinctions: isolation voltage is 4000Vrms (250Vrms higher than the main part), operating temperature range extends to -55°C ~ 100°C (wider than -40°C ~ 85°C), and output type is specified as Transistor with Base rather than Darlington with Base. SFH6318T is ROHS3 compliant and provides higher isolation voltage margin. Turn-on and turn-off times are 2µs each, compared to 1.6µs and 10µs for the main part.

All three parts share identical package form factor (8-SOIC), mounting type (Surface Mount), and core electrical parameters (current transfer ratio, output voltage, output current, forward voltage, and forward current). Selection among these parts should account for compliance requirements, temperature operating range needs, and specific timing characteristics required by the application circuit.

Frequently Asked Questions (FAQ)

Q: Can HCPL-0700-500E be used as a direct replacement for HCPL-0700#500?

A: Yes. HCPL-0700-500E is a parametric equivalent with identical electrical specifications, isolation voltage, current transfer ratio, output characteristics, and 8-SOIC package. The difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and RoHS compliance status. Electrical performance and PCB footprint compatibility are identical.

Q: What are the key differences between HCPL-0700#500 and SFH6318T?

A: Both parts meet the critical substitution parameters: 1-channel configuration, 3750Vrms minimum isolation (SFH6318T provides 4000Vrms), identical current transfer ratio range, 7V maximum output voltage, and 60mA output current. Differences include: SFH6318T has wider operating temperature range (-55°C to 100°C versus -40°C to 85°C), faster and more symmetric turn-on/turn-off times (2µs each versus 1.6µs/10µs), and output type specified as Transistor with Base rather than Darlington with Base. Both are ROHS3 compliant and use 8-SOIC packaging.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use 8-SOIC (0.154", 3.90mm Width) package with identical pin configuration for single-channel optoisolator with base output. PCB footprint and pinout are compatible across HCPL-0700#500, HCPL-0700-500E, and SFH6318T.

Q: Which part should be selected for new designs?

A: For new designs, HCPL-0700-500E or SFH6318T are preferred due to ROHS3 compliance. HCPL-0700-500E maintains identical specifications to the original part with improved compliance status. SFH6318T offers higher isolation voltage margin and extended temperature range, suitable for applications requiring wider operating conditions.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) affects supply chain logistics and handling but does not alter electrical specifications, performance characteristics, or PCB compatibility. Component electrical behavior remains identical regardless of packaging option.

Q: What is the significance of the higher isolation voltage in SFH6318T?

A: SFH6318T provides 4000Vrms isolation compared to 3750Vrms in HCPL-0700#500. This 250Vrms margin provides additional safety headroom in high-voltage isolation applications. If the circuit design requires exactly 3750Vrms isolation, both parts are functionally equivalent. If higher isolation voltage provides system-level benefits, SFH6318T offers this advantage.
