SL5504300 Equivalent & Substitute Parts

Part Overview

The SL5504300 is an optoisolator transistor with base output manufactured by onsemi, designed for high-voltage isolation applications requiring 5300Vrms isolation rating. This component features a single-channel configuration in a 6-DIP package and is rated for 100mA output current with a 1.23V typical forward voltage. The product is currently obsolete, making equivalent substitutes necessary for ongoing system support and new design implementations where this isolation performance is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL5504300 is determined by the following critical parameters:

• Isolation Voltage Rating: The substitute must meet or exceed 5300Vrms isolation specification
• Output Configuration: Transistor with base output is required for pin-compatible replacement
• Package Type: 6-DIP through-hole package ensures mechanical and electrical compatibility
• Single Channel: One-channel configuration must be maintained
• Input Type: DC input requirement must be preserved
• Output Current Capability: Minimum 100mA output current per channel
• Operating Temperature Range: Must support the required thermal operating window

The H11AV1VM from Fairchild Semiconductor is listed as an equivalent substitute. However, this substitute presents a lower isolation voltage rating (4170Vrms versus 5300Vrms), which represents a significant reduction in isolation performance. The substitute maintains identical package configuration, single-channel transistor output with base, and DC input type. Both components share the same 6-DIP through-hole mounting specification and comparable output saturation characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SL5504300 is classified as obsolete, necessitating component replacement for ongoing production and field support. The H11AV1VM substitute maintains mechanical and functional compatibility through identical 6-DIP package configuration and transistor output with base architecture.

Selection between these components must account for the following compliance and performance factors:

• Isolation Voltage Requirement: Applications requiring 5300Vrms isolation cannot use the H11AV1VM substitute, which is rated for 4170Vrms. This represents a 1130Vrms reduction in isolation capability.
• Temperature Operating Range: The SL5504300 supports -55°C to 100°C operation, while the H11AV1VM operates from -40°C to 100°C. Systems requiring sub-zero operation below -40°C cannot use the substitute.
• Output Voltage Rating: The SL5504300 supports 80V maximum output voltage compared to 70V for the substitute. Applications exceeding 70V output voltage require the main part.
• Current Transfer Ratio: The H11AV1VM provides higher minimum current transfer ratio (100% versus 25%), which may improve circuit performance in applications sensitive to gain variation.
• Response Time: The H11AV1VM exhibits faster switching characteristics (15µs versus 50µs turn-on time), beneficial for high-speed isolation applications.
• Regulatory Compliance: Both components carry EAR99 ECCN classification and HTSUS code 8541.49.8000, maintaining equivalent export compliance status.

Frequently Asked Questions (FAQ)

Q: Can the H11AV1VM directly replace the SL5504300 in all applications?

A: No. The H11AV1VM has a lower isolation voltage rating (4170Vrms versus 5300Vrms) and reduced maximum output voltage (70V versus 80V). Direct substitution is only valid for applications where these reduced ratings remain within system requirements.

Q: What is the primary difference between these two optoisolators?

A: The primary difference is isolation voltage rating. The SL5504300 provides 5300Vrms isolation, while the H11AV1VM provides 4170Vrms. Both share identical 6-DIP package configuration and transistor output with base topology.

Q: Are there temperature range limitations when using the H11AV1VM as a substitute?

A: Yes. The H11AV1VM operates from -40°C to 100°C, compared to the SL5504300 range of -55°C to 100°C. Applications requiring operation below -40°C cannot use the H11AV1VM substitute.

Q: Do both components use the same pinout?

A: Both components use 6-DIP through-hole packaging with identical physical dimensions (0.300", 7.62mm). Pin compatibility must be verified against specific application schematics, as transistor output with base configuration may have application-specific pin assignments.

Q: Which component has faster switching performance?

A: The H11AV1VM exhibits faster switching characteristics with 15µs turn-on and turn-off times, compared to 50µs turn-on and 150µs turn-off times for the SL5504300. This makes the H11AV1VM suitable for higher-speed isolation applications.

Q: Are both components subject to the same export regulations?

A: Yes. Both the SL5504300 and H11AV1VM carry EAR99 ECCN classification and HTSUS code 8541.49.8000, indicating equivalent export compliance status.
