H11G2S Optoisolator Equivalent & Substitute Parts

Part Overview

The H11G2S is an optoisolator with Darlington output and base connection, manufactured by onsemi. This component provides 5300Vrms isolation in a 6-SMD surface mount package. The H11G2S is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the H11G2S is determined by the following critical parameters:

• Output Type: Darlington with Base (all substitutes maintain this configuration)
• Number of Channels: Single channel (1)
• Voltage - Output (Max): 80V maximum (all substitutes comply)
• Current Transfer Ratio (Min): 1000% @ 10mA (maintained across active substitutes)
• Vce Saturation (Max): 1V or lower (all substitutes meet or exceed this specification)
• Input Type: DC (consistent across all parts)
• Mounting Type and Package: Surface mount 6-SMD, Gull Wing preferred for direct replacement

The H11G2S has two primary substitute categories:

Direct Functional Substitutes (Same Base Product Number H11G2):

• H11G2SM: Active status, surface mount 6-SMD package, lower isolation voltage (4170Vrms)
• H11G2SMT&R: Active status, surface mount 6-SMD package, alternative manufacturer (Isocom Components 2004 LTD)

Alternative Package Substitute (Same Base Product Number H11G2):

• H11G2M: Active status, through-hole 6-DIP package, lower isolation voltage (4170Vrms)

Parameter Comparison

Engineering Selection Recommendations

For Surface Mount Applications (Preferred Direct Replacement):

H11G2SM is the primary substitute for the H11G2S. Both parts share the same 6-SMD, Gull Wing surface mount package and base product number (H11G2). H11G2SM is active status with ROHS3 compliance. The isolation voltage is lower (4170Vrms versus 5300Vrms), which must be evaluated against circuit requirements. All other electrical parameters remain equivalent.

For Alternative Manufacturer Requirement:

H11G2SMT&R, manufactured by Isocom Components 2004 LTD, maintains the same 6-SMD surface mount package and Darlington output configuration. This part is active status with ROHS3 compliance. Note that isolation voltage specification differs (7.5Vpk versus 5300Vrms), and current transfer ratio is not specified. This part is suitable only when isolation voltage requirements are confirmed compatible.

For Through-Hole Applications:

H11G2M provides an alternative for designs requiring through-hole mounting. This part uses a 6-DIP package instead of surface mount. H11G2M is active status with ROHS3 compliance. The isolation voltage is lower (4170Vrms), and operating temperature range is narrower (-40°C to 100°C versus -55°C to 100°C). All substitute parts are REACH Unaffected and classified as EAR99.

Frequently Asked Questions (FAQ)

Q: Can H11G2SM directly replace H11G2S in existing designs?

A: H11G2SM shares the same 6-SMD surface mount package and electrical output characteristics (Darlington with Base, 80V max output, 1V Vce saturation). The primary difference is isolation voltage: H11G2SM provides 4170Vrms versus H11G2S at 5300Vrms. Direct replacement is possible only if circuit isolation requirements are satisfied by 4170Vrms.

Q: What is the difference between H11G2SM and H11G2SMT&R?

A: Both parts use 6-SMD surface mount packages. H11G2SM is manufactured by onsemi with 4170Vrms isolation. H11G2SMT&R is manufactured by Isocom Components 2004 LTD with 7.5Vpk isolation specification. The isolation voltage specifications are not directly comparable due to different measurement units (Vrms versus Vpk). Verify isolation requirements before selection.

Q: Is H11G2M suitable as a substitute?

A: H11G2M is functionally equivalent but uses a 6-DIP through-hole package instead of surface mount. This requires PCB redesign. H11G2M provides 4170Vrms isolation and operates from -40°C to 100°C. Use H11G2M only when through-hole mounting is required and isolation voltage of 4170Vrms is acceptable.

Q: Are all substitute parts RoHS compliant?

A: H11G2SM, H11G2SMT&R, and H11G2M are all ROHS3 compliant. The original H11G2S RoHS status is not specified in available data.

Q: What is the operating temperature range difference?

A: H11G2S operates from -55°C to 100°C. H11G2SM and H11G2M operate from -40°C to 100°C. H11G2SMT&R operates from -25°C to 100°C. Applications requiring operation below -40°C must use H11G2S or confirm compatibility with alternative temperature ranges.
