Substitute Part Grouping Explanation

Substitute parts for the EL3H7(EB)-VG are identified through parametric equivalence. All substitute parts maintain identical electrical specifications across the critical isolation voltage (3750Vrms), current transfer ratio range (50% to 600% @ 5mA), output voltage rating (80V maximum), and output current capacity (50mA per channel). The substitutes differ only in packaging format and inventory availability, not in functional performance or electrical characteristics.

The substitution logic is based on the following key parameters:

• Isolation voltage: 3750Vrms
• Output type: Transistor
• Current transfer ratio: 50% minimum, 600% maximum @ 5mA
• Maximum output voltage: 80V
• Output current: 50mA
• Vce saturation: 200mV maximum
• Operating temperature: -55°C to 110°C
• Surface mount configuration
• 4-pin SOIC package footprint

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are parametrically equivalent to the EL3H7(EB)-VG and are suitable for direct replacement in applications requiring 3750Vrms isolation with single-channel transistor output. Selection among the substitutes should be based on packaging requirements and supply availability.

EL3H7(EA)-VG (Everlight Electronics): Identical electrical specifications to the main part. Supplied in Tape & Reel format with 3852 units in stock. Suitable for automated assembly processes requiring reel packaging.

EL3H7(TA)-VG (Everlight Electronics): Identical electrical specifications to the main part. Supplied in Cut Tape and Digi-Reel format with 29910 units in stock. Highest inventory availability among Everlight variants. Suitable for both manual and automated assembly.

IS3H7 (Isocom Components): Parametrically equivalent with rise and fall times of 6µs and 6µs respectively, compared to 5µs and 3µs for Everlight variants. All other electrical parameters are identical. Supplied in Tape & Reel format with 45400 units in stock. Highest overall inventory availability.

All parts are ROHS3 compliant, carry MSL 1 rating, and operate across the -55°C to 110°C temperature range. Selection should prioritize packaging format compatibility with assembly equipment and supply chain lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can EL3H7(EA)-VG replace EL3H7(EB)-VG in my circuit?

A: Yes. Both parts are parametrically equivalent with identical isolation voltage (3750Vrms), current transfer ratio (50% to 600% @ 5mA), output voltage rating (80V), and output current capacity (50mA). The only difference is packaging format: EL3H7(EB)-VG is supplied in bulk, while EL3H7(EA)-VG is supplied in Tape & Reel. Electrical performance is identical.

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

A: Both parts have identical electrical specifications. The difference is in packaging format: EL3H7(EA)-VG is supplied in Tape & Reel (TR), while EL3H7(TA)-VG is supplied in Cut Tape (CT) and Digi-Reel format. EL3H7(TA)-VG has significantly higher inventory availability (29910 units vs. 3852 units).

Q: Is IS3H7 a direct substitute for EL3H7(EB)-VG?

A: IS3H7 is parametrically equivalent with one timing difference: rise and fall times are 6µs and 6µs respectively, compared to 5µs and 3µs for the EL3H7 variants. All other electrical parameters are identical, including isolation voltage, current transfer ratio, output voltage, and output current. The timing difference is within acceptable tolerance for most applications. IS3H7 has the highest inventory availability at 45400 units.

Q: Do all substitute parts have the same package footprint?

A: Yes. All parts use the 4-SOIC package with 0.173" width and 4.40mm width specification. They are mechanically compatible and can be used interchangeably on the same PCB layout.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting the same environmental and regulatory standards.

Q: Which substitute should I choose for high-volume production?

A: For high-volume automated assembly, EL3H7(TA)-VG is recommended due to highest inventory availability (29910 units) and Cut Tape/Digi-Reel packaging compatibility with standard pick-and-place equipment. IS3H7 offers the highest overall inventory (45400 units) if cross-manufacturer sourcing is acceptable.
