Electrical Equivalence Criteria:

• Voltage isolation rating: 5000Vrms
• Current transfer ratio range: 600% to 7500% @ 1mA
• Output type: Darlington configuration
• Maximum output voltage: 35V
• Maximum output current per channel: 80mA
• Vce saturation: 1V maximum
• Input type: DC
• Rise/Fall time: 60µs, 53µs

Mechanical Equivalence Criteria:

• Package type: 4-SMD, Gull Wing
• Mounting: Surface Mount
• Operating temperature range: -55°C ~ 110°C
• Moisture sensitivity: MSL 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All substitute parts listed are manufactured by Everlight Electronics Co Ltd and share the base product number EL815, differing only in suffix designations that do not alter functional performance within the specified parameter ranges.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can EL815(S)(TD) be used as a direct replacement for EL815(S)(TB)-V?

A: Yes. The EL815(S)(TD) is a parametric equivalent with identical electrical specifications (5000Vrms isolation, 600-7500% current transfer ratio, 35V maximum output, 80mA output current, 1V Vce saturation) and mechanical configuration (4-SMD Gull Wing surface mount package). The suffix designation change does not alter functional performance within the specified parameter ranges.

Q: What is the difference between the EL815(S) and EL815(S1) variants?

A: Both EL815(S) and EL815(S1) variants maintain identical electrical and mechanical parameters as specified in this reference. The suffix designation reflects internal manufacturing or qualification differences that do not affect circuit performance or compatibility.

Q: Are the "-V" suffix variants interchangeable with non "-V" variants?

A: Yes. Parts with and without the "-V" suffix designation maintain identical electrical specifications and mechanical packaging. The "-V" designation does not represent a functional parameter difference affecting substitution compatibility.

Q: What package configuration applies to all substitute parts?

A: All substitute parts use 4-SMD (Small Outline Dual In-line Package) with Gull Wing lead configuration for surface mount assembly. This package type is consistent across all listed alternatives and the original EL815(S)(TB)-V part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory compliance of the original EL815(S)(TB)-V.

Q: What is the operating temperature range for substitute parts?

A: All substitute parts operate across the temperature range of -55°C to 110°C, identical to the original EL815(S)(TB)-V specification.

Q: Can I mix different substitute part numbers in the same circuit board assembly?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications, allowing interchangeable use within the same design without circuit modification or performance variation.
