EL3H7(A)(EB)-VG Optoisolator Equivalent & Substitute Parts

Part Overview

The EL3H7(A)(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 unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across isolation voltage, current transfer ratio, output specifications, and package form factor. Alternative models may be required due to inventory availability, packaging format preferences, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL3H7(A)(EB)-VG is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Isolation voltage: 3750Vrms (exact match required)
• Number of channels: 1 (single channel configuration)
• Current transfer ratio range: 80% to 160% @ 5mA (identical specification)
• Output type: Transistor (same output topology)
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Vce saturation: 200mV maximum
• Rise and fall time: 5µs and 3µs respectively
• Forward voltage: 1.2V typical
• Maximum forward current: 50mA

Mechanical Equivalence Criteria:

• Package type: 4-SOIC (0.173", 4.40mm Width)
• Mounting type: Surface Mount
• Input type: DC

Compliance Equivalence Criteria:

• Product status: Active
• RoHS3 compliance required
• Moisture sensitivity level: MSL 1

The substitute part EL3H7(A)(EA)-G meets all electrical, mechanical, and compliance requirements. The primary difference is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the main part's standard packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the EL3H7(A)(EB)-VG and EL3H7(A)(EA)-G are Active status products with full ROHS3 compliance and MSL 1 rating. Selection between these parts is based on packaging and supply requirements rather than electrical performance.

EL3H7(A)(EB)-VG is appropriate for applications requiring standard packaging format with current inventory of 900 pieces available.

EL3H7(A)(EA)-G is appropriate for high-volume production environments or automated assembly processes requiring Tape & Reel packaging format, with higher inventory availability of 2845 pieces.

Both parts are electrically and mechanically interchangeable within the same PCB design and assembly process. No circuit modifications or design changes are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can EL3H7(A)(EA)-G be used as a direct replacement for EL3H7(A)(EB)-VG?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus standard packaging). PCB footprint, electrical performance, and thermal characteristics are identical.

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

A: The part numbers differ in their packaging designation suffix. EL3H7(A)(EB)-VG uses standard packaging, while EL3H7(A)(EA)-G uses Tape & Reel (TR) format. All electrical specifications, isolation voltage, current transfer ratio, output characteristics, and operating temperature range are identical.

Q: Are there any compatibility issues when switching between these parts?

A: No compatibility issues exist. Both parts use the same 4-SOIC (0.173", 4.40mm Width) package with identical pin configuration and spacing. Assembly equipment compatibility depends on whether your process handles Tape & Reel or standard packaging formats.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EL3H7(A)(EB)-VG and EL3H7(A)(EA)-G are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry the same ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Q: Which part should be selected for high-volume production?

A: EL3H7(A)(EA)-G with Tape & Reel packaging is optimized for high-volume automated assembly. It offers higher inventory availability (2845 pieces) and is compatible with standard pick-and-place equipment.

Q: What is the isolation voltage specification for both parts?

A: Both parts provide 3750Vrms isolation voltage with a single channel configuration. This specification is identical across both part numbers.

Q: Are the current transfer ratio specifications identical?

A: Yes. Both parts specify a current transfer ratio range of 80% to 160% at 5mA input current. This parameter is identical and determines the optical coupling efficiency between input and output stages.
