EL3H7(B)(EB)-VG Equivalent & Substitute Parts

Part Overview

The EL3H7(B)(EB)-VG is an optoisolator with transistor output manufactured by Everlight Electronics Co Ltd. This component provides galvanic isolation up to 3750Vrms with a single channel configuration in a 4-SSOP surface mount package. The part is classified as Active product status with full RoHS3 compliance and MSL Level 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when electrical parameters, isolation voltage, output characteristics, and mechanical packaging remain identical across different packaging or tape configurations. This ensures direct functional equivalence in circuit applications without design modification.

Substitute Part Grouping Explanation

Substitute parts for the EL3H7(B)(EB)-VG are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Isolation voltage: 3750Vrms
• Number of channels: 1
• Current transfer ratio range: 130% to 260% @ 5mA
• Output type: Transistor
• Maximum output voltage: 80V
• Output current per channel: 50mA
• Forward voltage: 1.2V typical
• Maximum forward current: 50mA
• Vce saturation: 200mV maximum
• Rise/fall time: 5µs, 3µs typical

Mechanical Parameters (Must Match Exactly):

• Package type: 4-SOIC (0.173", 4.40mm Width)
• Mounting type: Surface Mount
• Supplier device package: 4-SSOP

Compliance & Status (Must Match Exactly):

• Product status: Active
• RoHS3 compliance: Required
• MSL rating: Level 1

The EL3H7(B)(EB)-VG differs from its substitute only in packaging configuration (tape reel type), which does not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The EL3H7(B)(EB)-VG and EL3H7(B)(TA)-VG are electrically and mechanically equivalent optoisolators. Both parts maintain identical electrical specifications, isolation ratings, and thermal operating ranges. Both are Active status products with full RoHS3 compliance and MSL Level 1 certification.

Selection between these parts is determined by procurement and assembly requirements:

EL3H7(B)(EB)-VG is supplied in standard packaging configuration with 794 units currently in stock inventory.

EL3H7(B)(TA)-VG is supplied in Cut Tape (CT) and Digi-Reel® packaging with 1506 units currently in stock inventory, offering higher availability and alternative tape reel options for automated assembly processes.

Both parts are suitable for direct substitution in circuit designs without modification to PCB layout, schematic connections, or component footprints. The choice between them depends on inventory availability, tape reel compatibility with pick-and-place equipment, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can EL3H7(B)(TA)-VG replace EL3H7(B)(EB)-VG in an existing design?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters, isolation voltage, output characteristics, operating temperature range, and package dimensions are equivalent. No circuit design changes are required.

Q: What is the difference between these two part numbers?

A: The only difference is the packaging configuration. EL3H7(B)(EB)-VG uses standard packaging, while EL3H7(B)(TA)-VG is supplied in Cut Tape (CT) and Digi-Reel® format. This affects how components are delivered and handled during assembly but does not affect electrical performance.

Q: Are the PCB footprints identical?

A: Yes. Both parts use the 4-SOIC package with 0.173" width and 4.40mm dimensions. PCB footprints, land patterns, and mounting requirements are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EL3H7(B)(EB)-VG and EL3H7(B)(TA)-VG are RoHS3 compliant with MSL Level 1 rating. Both carry ECCN EAR99 and HTSUS 8541.49.8000 classifications.

Q: Which part should I select for high-volume production?

A: Selection depends on your assembly equipment and supply chain. EL3H7(B)(TA)-VG in Cut Tape and Digi-Reel® format is typically preferred for automated pick-and-place assembly. EL3H7(B)(EB)-VG may be selected based on current inventory availability or specific procurement agreements.

Q: Are the current transfer ratios identical?

A: Yes. Both parts specify 130% minimum and 260% maximum current transfer ratio at 5mA input current. Rise and fall times are also identical at 5µs and 3µs respectively.

Q: Can I use these parts interchangeably in my supply chain?

A: Yes, provided your assembly process can accommodate the packaging format. If your equipment is configured for Cut Tape and Digi-Reel® formats, EL3H7(B)(TA)-VG is the direct substitute. If your process uses standard packaging, EL3H7(B)(EB)-VG is appropriate. Both deliver identical circuit performance.
