H11B2-X009 Equivalent & Substitute Parts

Part Overview

The H11B2-X009 is an optoisolator with Darlington output and base connection, rated for 5300Vrms isolation voltage. Manufactured by Vishay Semiconductor Opto Division, this component is classified as obsolete. Due to its discontinued status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H11B2-X009 are grouped based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Single channel Darlington output with base connection
• Surface mount 6-SMD, Gull Wing package
• DC input type
• Operating temperature range: -55°C ~ 100°C
• RoHS3 compliance and MSL 1 rating
• Active product status from established manufacturers

Isolation Voltage Grouping:

• 5300Vrms Group: MCA230SM, MCA230SMT&R (exact isolation match)
• 5000Vrms Group: H11B2S1(TA), MCA231SM, MCA231SMT&R (5% reduction acceptable for most applications)
• 7.5Vpk Group: H11B2SM, H11B2SMT&R (lower isolation voltage; application-dependent)

Current Transfer Ratio Consideration:

• H11B2-X009 specifies 200% @ 1mA minimum
• MCA230 series specifies 100% @ 10mA (lower gain, different test condition)
• MCA231 and H11B2S1(TA) specify 200% @ 1mA (direct match)

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Equivalents (5300Vrms Isolation): MCA230SM and MCA230SMT&R maintain the exact 5300Vrms isolation voltage specification of the H11B2-X009. Both are active products from Isocom Components with full RoHS3 compliance and MSL 1 rating. The primary difference is packaging: MCA230SM is supplied in tube format, while MCA230SMT&R is supplied in tape and reel. Selection between these depends on production volume and assembly requirements. Note that MCA230 series specifies 100% current transfer ratio at 10mA test condition, which differs from the original 200% @ 1mA specification.

Tier 2 - High Compatibility (5000Vrms Isolation): H11B2S1(TA) from Everlight Electronics and MCA231SM/MCA231SMT&R from Isocom operate at 5000Vrms isolation, representing a 5.7% reduction from the original specification. H11B2S1(TA) offers the highest maximum output voltage (55V) among all substitutes. MCA231 variants maintain the 200% current transfer ratio specification. All three are active products with full compliance certifications. MCA231SM and MCA231SMT&R differ only in packaging format.

Tier 3 - Application-Dependent (7.5Vpk Isolation): H11B2SM and H11B2SMT&R from Isocom are direct H11B2 base product variants but operate at significantly lower isolation voltage (7.5Vpk). These are suitable only for applications where the reduced isolation voltage meets system requirements. Both maintain 200% current transfer ratio and are available in tube and tape-reel formats respectively.

Compliance and Availability: All substitute parts carry ROHS3 compliance, MSL 1 rating, and EAR99 export classification matching the original component. All are currently in active production status with established inventory levels.

Frequently Asked Questions (FAQ)

Q: Can I directly replace H11B2-X009 with any of these substitutes? A: Direct replacement depends on your isolation voltage requirement. For applications requiring 5300Vrms isolation, use MCA230SM or MCA230SMT&R. For 5000Vrms applications, H11B2S1(TA), MCA231SM, or MCA231SMT&R are suitable. H11B2SM and H11B2SMT&R are only compatible with designs tolerating 7.5Vpk isolation.

Q: What is the difference between tube and tape-reel packaging? A: Tube packaging (SM designation) is suitable for lower-volume production and manual assembly. Tape-reel packaging (SMT&R designation) is designed for automated pick-and-place assembly equipment and higher production volumes. Both contain identical components; packaging format is the only difference.

Q: Why do MCA230 parts specify 100% current transfer ratio while others specify 200%? A: Current transfer ratio is measured at different test conditions. MCA230 is tested at 10mA input current, while H11B2-X009 and other substitutes are tested at 1mA. The lower test current in the original specification results in higher measured gain. For circuit design purposes, use the specified test condition values from the datasheet of your selected substitute.

Q: Are all substitutes RoHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 Compliant certification and MSL 1 (Unlimited) moisture sensitivity rating, matching the original H11B2-X009 specifications.

Q: Which substitute offers the best performance match? A: MCA231SM and MCA231SMT&R provide the closest electrical match, maintaining 5000Vrms isolation, 200% current transfer ratio at 1mA test condition, and identical turn-on/turn-off timing characteristics to the original. For exact 5300Vrms isolation matching, MCA230SM and MCA230SMT&R are required, though with different current transfer ratio test conditions.

Q: Can I mix substitutes from different manufacturers in the same design? A: Yes. All substitutes share identical package geometry (6-SMD, Gull Wing), pinout, and functional specifications within their respective isolation voltage groups. Cross-manufacturer substitution is electrically compatible provided isolation voltage requirements are met.
