Substitute Part Grouping Explanation

Substitution of the EL3H7(C)(EB)-VG is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for valid substitution:

• Voltage - Isolation: 3750Vrms
• Number of Channels: 1
• Current Transfer Ratio range: 200% to 400% @ 5mA
• Rise / Fall Time: 5µs, 3µs
• Input Type: DC
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Voltage - Forward (Vf) (Typ): 1.2V
• Current - DC Forward (If) (Max): 50mA
• Vce Saturation (Max): 200mV
• Operating Temperature: -55°C ~ 110°C
• Package / Case: 4-SOIC (0.173", 4.40mm Width)
• Supplier Device Package: 4-SSOP
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed below meet these criteria. Variations in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete) do not affect electrical or mechanical compatibility. The base product number EL3H7 remains constant across all equivalents.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by Everlight Electronics Co Ltd and maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. The primary distinction between the main part EL3H7(C)(EB)-VG and its substitutes is product status classification.

EL3H7(C)(EB)-VG carries Obsolete status. For new designs or ongoing production requiring long-term component availability, selection of an Active status variant is appropriate.

Active Status Alternatives:

• EL3H7(C)(EB)-G: Maintains identical electrical specifications and bulk packaging format. Inventory of 773 units available.
• EL3H7(C)(EA)-G and EL3H7(C)(EA)-VG: Tape & Reel packaging options with 1065 and 725 units respectively.
• EL3H7(C)(TA)-G and EL3H7(C)(TA)-VG: Tape & Reel packaging with highest inventory availability at 185200 and 2100 units respectively.
• EL3H7(C)(TB)-G and EL3H7(C)(TB)-VG: Tape & Reel packaging with 1064 and 794 units available.

Selection between Active variants depends on packaging requirements (bulk versus Tape & Reel) and inventory availability. All Active variants support equivalent circuit functionality and board-level integration without design modification.

Frequently Asked Questions (FAQ)

Q: Can EL3H7(C)(EB)-VG be directly replaced with EL3H7(C)(TA)-G on an existing PCB?

A: Yes. Both parts share identical electrical parameters (3750Vrms isolation, 200-400% CTR @ 5mA, 50mA output current, -55°C to 110°C operating range) and mechanical specifications (4-SSOP package, 4.40mm width). The difference in packaging format (bulk versus Tape & Reel) does not affect PCB assembly compatibility. The component footprint and pinout are identical.

Q: What is the difference between the "-G" and "-VG" suffix variants?

A: The "-G" and "-VG" suffixes represent different packaging formats. "-G" indicates standard packaging, while "-VG" indicates an alternative packaging specification. Both maintain identical electrical and thermal characteristics. Selection between these variants depends on procurement and assembly process requirements rather than circuit performance.

Q: Why is EL3H7(C)(EB)-VG marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production of this specific variant. However, equivalent Active variants within the EL3H7 family remain in production. Substitution with an Active variant ensures access to current manufacturing stock and ongoing supplier support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including the main part EL3H7(C)(EB)-VG, carry ROHS3 compliance certification. This compliance status is consistent across the entire EL3H7 product family.

Q: What is MSL Level 1 (Unlimited) moisture sensitivity?

A: MSL Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part does not require special moisture control during storage, handling, or assembly. Standard warehouse and manufacturing conditions are acceptable.

Q: Which substitute offers the best inventory availability?

A: EL3H7(C)(TA)-G provides the highest inventory level at 185200 units. This variant is suitable for high-volume production requirements or long-term supply chain security.

Q: Can substitute parts be mixed in the same production batch?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different EL3H7 variants in the same assembly does not affect circuit performance or reliability. However, procurement and quality control procedures should document which variant is used in each production lot.
