EL3H7(C)(EA)-VG Equivalent & Substitute Parts

Part Overview

The EL3H7(C)(EA)-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. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for optoisolator components is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Isolation voltage rating (3750Vrms)
• Current transfer ratio range (200% to 400% @ 5mA)
• Output transistor characteristics (Vce saturation, maximum output voltage, maximum output current)
• Rise and fall time specifications (5µs / 3µs)
• Input type (DC) and output type (Transistor)
• Operating temperature range (-55°C to 110°C)

Mechanical Equivalence Criteria:

• Package type (4-SOIC, 0.173" width, 4.40mm)
• Surface mount configuration
• Pin count and pinout compatibility

Compliance Equivalence Criteria:

• RoHS3 compliance status
• Moisture sensitivity level (MSL 1)
• ECCN and HTSUS classifications

The substitute part EL3H7(C)(TA)-VG meets all specified electrical, mechanical, and compliance parameters and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations

Primary Part Selection: EL3H7(C)(EA)-VG

The EL3H7(C)(EA)-VG is the specified component for this application. Current inventory status shows 725 pieces in stock. This part maintains Active product status with full RoHS3 compliance and MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions.

Substitute Part Selection: EL3H7(C)(TA)-VG

The EL3H7(C)(TA)-VG is a parametric equivalent substitute with identical electrical, mechanical, and compliance specifications. This part is available with higher inventory (2100 pieces in stock) and carries identical Active product status, RoHS3 compliance, and MSL Level 1 rating. The substitute part includes REACH Unaffected status documentation.

Selection Criteria:

Both parts are suitable for direct substitution in applications requiring 3750Vrms isolation, single-channel transistor output optoisolators in 4-SSOP surface mount packages. Selection between the two should be based on:

• Inventory availability and lead time requirements
• Supply chain logistics and regional sourcing preferences
• Packaging quantity requirements (Tape & Reel format for both)
• Compliance documentation requirements (REACH status if applicable)

No electrical or mechanical redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can EL3H7(C)(TA)-VG be used as a direct replacement for EL3H7(C)(EA)-VG?

A: Yes. Both parts are parametric equivalents with identical isolation voltage (3750Vrms), current transfer ratio (200-400% @ 5mA), output characteristics (80V max, 50mA max per channel), timing specifications (5µs/3µs rise/fall), and operating temperature range (-55°C to 110°C). Package type, mounting configuration, and compliance ratings are identical.

Q: Are there any differences in the 4-SSOP package between these parts?

A: No. Both parts use identical 4-SOIC (0.173", 4.40mm Width) package specifications with 4-SSOP supplier device package designation. Pin count, pinout, and PCB footprint are identical.

Q: What is the significance of the (EA) and (TA) designations in the part numbers?

A: These designations indicate different packaging or tape reel configurations within the same base product (EL3H7). Both variants meet identical electrical and mechanical specifications and are interchangeable at the component level.

Q: Do both parts have the same RoHS and MSL compliance?

A: Yes. Both EL3H7(C)(EA)-VG and EL3H7(C)(TA)-VG are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. The substitute part additionally documents REACH Unaffected status.

Q: What inventory considerations should guide part selection?

A: EL3H7(C)(EA)-VG has 725 pieces in stock, while EL3H7(C)(TA)-VG has 2100 pieces available. For applications with extended lead time requirements or high-volume procurement, the substitute part offers greater inventory availability without compromising electrical or mechanical performance.

Q: Are there any temperature or isolation voltage limitations when using the substitute part?

A: No. Both parts operate identically across the full temperature range (-55°C to 110°C) and maintain 3750Vrms isolation voltage specifications. No derating or operational limitations apply to the substitute part.
