H11G2W Equivalent & Substitute Parts

Part Overview

The H11G2W is an optoisolator with Darlington output manufactured by onsemi, featuring 5300Vrms isolation voltage in a 6-DIP through-hole package. This component provides galvanic isolation for DC input signals with Darlington output configuration including base connection. The H11G2W is classified as obsolete, making equivalent or substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H11G2W are identified based on the following critical parameters that determine functional compatibility:

• Package / Case: 6-DIP (0.400", 10.16mm) — mechanical and pin compatibility requirement
• Mounting Type: Through Hole — PCB assembly compatibility
• Output Type: Darlington with Base — functional output configuration
• Number of Channels: 1 — single-channel isolation
• Input Type: DC — signal type compatibility
• Voltage - Output (Max): 80V — maximum output voltage rating
• Vce Saturation (Max): 1V or lower — saturation performance
• Voltage - Forward (Vf) (Typ): 1.2V–1.3V — input LED forward voltage range

The H11G2W lists two substitute parts: H11G2TVM (direct manufacturer substitute from onsemi) and H11G2G (similar part from Isocom Components 2004 LTD). Both maintain the same package, mounting type, output configuration, and core electrical characteristics within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

H11G2TVM (onsemi) — Direct manufacturer substitute with active product status. Maintains identical current transfer ratio (1000% @ 10mA), output voltage (80V), saturation voltage (1V), and switching times (5µs, 100µs). Isolation voltage is reduced to 4170Vrms compared to the H11G2W's 5300Vrms. Operating temperature range is -40°C to 100°C versus -55°C to 100°C. RoHS3 compliant. Suitable for applications where the lower isolation voltage and reduced low-temperature operating range are acceptable.

H11G2G (Isocom Components 2004 LTD) — Similar part with active product status and RoHS3 compliance. Maintains 80V maximum output voltage and Darlington with base configuration. Isolation voltage specification differs (7.5Vpk). Current transfer ratio, switching times, and rise/fall time specifications are not provided. Operating temperature range is -25°C to 100°C. Forward voltage is 1.2V (versus 1.3V), and maximum forward current is 50 mA (versus 60 mA). Vce saturation is 1.2V (versus 1V). Suitable for applications with relaxed low-temperature requirements and where the specified electrical parameters align with design needs.

Frequently Asked Questions (FAQ)

Q: Can H11G2TVM directly replace H11G2W in all applications?

A: H11G2TVM maintains the same package (6-DIP), output configuration (Darlington with base), and key electrical parameters (current transfer ratio, output voltage, saturation voltage, switching times). The primary differences are lower isolation voltage (4170Vrms versus 5300Vrms) and reduced low-temperature operating range (-40°C versus -55°C). Substitution is valid only if your application does not require the higher isolation voltage or extended low-temperature operation.

Q: What are the key differences between H11G2TVM and H11G2G?

A: Both are active products in 6-DIP packages with Darlington output. H11G2TVM is from onsemi with specified current transfer ratio and switching times matching the H11G2W. H11G2G is from Isocom Components with different isolation voltage specification (7.5Vpk), unspecified current transfer ratio and switching times, lower forward voltage (1.2V), lower maximum forward current (50 mA), and higher saturation voltage (1.2V). H11G2TVM provides closer electrical alignment to the H11G2W.

Q: Are both substitute parts RoHS compliant?

A: Yes. H11G2TVM is RoHS3 compliant. H11G2G is RoHS3 compliant. The H11G2W status is not specified in the provided data.

Q: What is the impact of isolation voltage differences?

A: H11G2W specifies 5300Vrms isolation. H11G2TVM specifies 4170Vrms. H11G2G specifies 7.5Vpk. Isolation voltage determines the maximum voltage differential that can be safely applied across the optoisolator's isolation barrier. Applications requiring 5300Vrms isolation cannot use H11G2TVM. Applications with lower isolation requirements can use either substitute.

Q: Are the operating temperature ranges compatible?

A: H11G2W operates from -55°C to 100°C. H11G2TVM operates from -40°C to 100°C. H11G2G operates from -25°C to 100°C. If your application requires operation below -40°C, only the H11G2W meets the specification. For applications operating above -40°C, both substitutes are suitable.

Q: Do all three parts use the same package and pinout?

A: Yes. All three parts use 6-DIP (0.400", 10.16mm) through-hole packages with identical mechanical dimensions and pin spacing, ensuring direct PCB compatibility without layout modifications.
