EL3H7(EB)-G Optoisolator Equivalent & Substitute Parts

Part Overview

The EL3H7(EB)-G 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 protection.

Substitute parts are necessary when the primary part number becomes unavailable, when specific packaging formats are required for manufacturing processes, or when inventory constraints necessitate alternative sourcing from qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

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

Electrical Equivalence Criteria:

• Voltage - Isolation: 3750Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Current Transfer Ratio range: 50% to 600% @ 5mA (mandatory match)
• Output Type: Transistor (mandatory match)
• Voltage - Output (Max): 80V (mandatory match)
• Current - Output / Channel: 50mA (mandatory match)
• Vce Saturation (Max): 200mV (mandatory match)
• Operating Temperature Range: -55°C ~ 110°C (mandatory match)

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount (mandatory match)
• Package / Case: 4-SOIC (0.173", 4.40mm Width) (mandatory match)

Compliance Criteria:

• RoHS3 Compliant status
• MSL Level 1 rating

All substitute parts listed maintain identical electrical performance and mechanical compatibility. Differences exist only in packaging format (Tape & Reel, Cut Tape & Digi-Reel®) and manufacturer identity, which do not affect circuit-level functionality or board assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the EL3H7(EB)-G. Selection between alternatives is determined by packaging and sourcing requirements rather than performance characteristics.

EL3H7(EA)-VG (Everlight Electronics Co Ltd, Tape & Reel format) is suitable for high-volume automated assembly processes requiring continuous reel feeding. This variant provides 3852 units in current inventory.

EL3H7(TA)-VG (Everlight Electronics Co Ltd, Cut Tape & Digi-Reel® format) accommodates both manual and semi-automated pick-and-place operations. This variant provides the highest current inventory at 29910 units, supporting extended lead time requirements.

IS3H7 (Isocom Components 2004 LTD, Tape & Reel format) represents a cross-manufacturer equivalent from an alternative qualified supplier. Rise and fall times are specified at 6µs and 6µs respectively, compared to 5µs and 3µs for Everlight variants. This part maintains all critical electrical parameters and RoHS3 compliance. Current inventory is 45400 units.

All substitute parts carry Active product status and full RoHS3 compliance certification, confirming ongoing manufacturer support and environmental regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can EL3H7(EA)-VG replace EL3H7(EB)-G in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, isolation voltage, output current ratings, and operating temperature range. The difference is packaging format: EL3H7(EA)-VG uses Tape & Reel format while EL3H7(EB)-G uses bulk packaging. Circuit-level performance is identical.

Q: What is the difference between EL3H7(TA)-VG and EL3H7(EA)-VG?

A: Both are Everlight Electronics Co Ltd products with identical electrical specifications. The difference is packaging: EL3H7(TA)-VG uses Cut Tape & Digi-Reel® format suitable for mixed manual and automated assembly, while EL3H7(EA)-VG uses standard Tape & Reel format for continuous automated feeding. Electrical performance is identical.

Q: Is IS3H7 from Isocom a direct substitute?

A: Yes. IS3H7 meets all critical electrical parameters: 3750Vrms isolation, 50-600% current transfer ratio, 80V maximum output voltage, 50mA output current, and 200mV maximum Vce saturation. Operating temperature range and package dimensions are identical. The rise and fall times are specified at 6µs and 6µs respectively, compared to 5µs and 3µs for Everlight variants, but this does not affect functional equivalence. IS3H7 carries RoHS3 compliance and MSL Level 1 rating.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts use identical 4-SOIC (0.173", 4.40mm Width) package dimensions and surface mount configuration. PCB footprints, solder pad layouts, and assembly processes are compatible across all listed parts.

Q: What inventory considerations apply to substitute selection?

A: EL3H7(TA)-VG offers the highest current inventory at 29910 units, supporting extended production runs. IS3H7 provides 45400 units from an alternative manufacturer. EL3H7(EA)-VG offers 3852 units. EL3H7(EB)-G (bulk format) has 813 units in stock. Inventory levels should be evaluated against production volume and lead time requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts carry RoHS3 Compliant certification and MSL Level 1 (Unlimited) moisture sensitivity rating, confirming compliance with environmental regulations and suitability for standard storage and handling conditions.
