SL5511300 Equivalent & Substitute Parts

Part Overview

The SL5511300 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 25% minimum current transfer ratio at 2mA input.

The SL5511300 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this isolation voltage and package configuration are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL5511300 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Single-channel optoisolator configuration
• Transistor output with base connection
• 6-DIP through-hole package (0.300", 7.62mm)
• DC input type
• Operating temperature range compatibility

Secondary Compatibility Criteria:

• Isolation voltage rating (minimum 4170Vrms acceptable for applications not requiring the full 5300Vrms specification)
• Output voltage rating (minimum 30V required)
• Vce saturation characteristics (400mV maximum)
• Current transfer ratio performance at specified input current levels

The H11AV1VM from Fairchild Semiconductor meets the primary package and functional requirements. However, the isolation voltage rating is lower (4170Vrms versus 5300Vrms), and the maximum output voltage is higher (70V versus 30V). These differences must be evaluated against specific application requirements.

Engineering Selection Recommendations

SL5511300 (onsemi) — Obsolete Status: The SL5511300 is no longer in active production. Component sourcing is limited to existing inventory. This part should be considered end-of-life for new designs.

H11AV1VM (Fairchild Semiconductor) — Active Status: The H11AV1VM is an active product with substantial inventory availability (12,300 pcs). This part is suitable for applications where the 4170Vrms isolation rating meets system requirements. The higher maximum output voltage (70V) and improved current transfer ratio performance provide additional design margin in many applications.

Compliance and Certifications: Both parts carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, indicating equivalent regulatory treatment for export and tariff purposes.

Selection Basis: Choose the H11AV1VM for new designs and production where isolation voltage requirements do not exceed 4170Vrms. The active product status ensures long-term availability and supply chain stability. Retain the SL5511300 only for legacy system maintenance where the higher 5300Vrms isolation specification is mandatory.

Frequently Asked Questions (FAQ)

Q: Can the H11AV1VM directly replace the SL5511300 in existing designs?

A: Direct replacement is possible only if the application isolation voltage requirement does not exceed 4170Vrms. The H11AV1VM provides lower isolation voltage but higher maximum output voltage and superior current transfer ratio. PCB layout and component footprint are identical (6-DIP package). Verify isolation voltage requirements in your system specification before substitution.

Q: What is the significance of the different current transfer ratio specifications?

A: The SL5511300 specifies 25% minimum CTR at 2mA input current, while the H11AV1VM specifies 100% minimum CTR at 10mA input current. These are measured at different input current levels. The H11AV1VM demonstrates higher CTR performance at its specified test point, which may reduce input current requirements in your circuit design.

Q: Are there temperature range differences that affect compatibility?

A: The SL5511300 operates from -55°C to 100°C, while the H11AV1VM operates from -40°C to 100°C. If your application requires operation below -40°C, the SL5511300 specification is necessary. For standard industrial temperature ranges (-40°C to 85°C), both parts are compatible.

Q: What does the 6-DIP package specification mean for PCB design?

A: Both parts use the 6-DIP (Dual In-line Package) with 0.300-inch (7.62mm) body width. Pin spacing and footprint are identical, allowing direct PCB substitution without layout modifications. Through-hole mounting is required for both components.

Q: How do the isolation voltage ratings affect circuit design?

A: Isolation voltage rating determines the maximum voltage differential that can be safely applied across the optoisolator's isolation barrier. The SL5511300 supports 5300Vrms isolation, while the H11AV1VM supports 4170Vrms. Select based on your system's maximum isolation voltage requirement. Exceeding the rated isolation voltage risks component failure and safety hazards.

Q: Is the H11AV1VM suitable for high-voltage switching applications?

A: The H11AV1VM maximum output voltage rating is 70V, compared to 30V for the SL5511300. This higher rating provides greater flexibility for high-voltage switching circuits. However, verify that your circuit design does not exceed the 4170Vrms isolation specification, which is the primary limiting factor for high-voltage applications.
