All substitute parts are manufactured by Everlight Electronics Co Ltd and share the base product number EL815. Substitution is valid across all identified part variants without electrical or mechanical derating.

Parameter Comparison

Engineering Selection Recommendations

The EL815(S)(TA)-V is discontinued at DiGi Electronics. All identified substitute parts are active products manufactured by Everlight Electronics Co Ltd with identical electrical and mechanical specifications. Selection among substitute parts should be based on:

Product Availability: All substitute parts maintain active product status with current inventory levels ranging from 734 to 1145 pieces.

Compliance Certification: All substitute parts carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental qualifications.

Thermal Performance: All substitute parts operate across the identical temperature range of -55°C to 110°C, supporting equivalent thermal design requirements.

Electrical Performance: All substitute parts deliver identical isolation voltage (5000Vrms), current transfer ratio (600% to 7500% @ 1mA), output current capability (80mA), and switching characteristics (60µs rise time, 53µs fall time).

Package Compatibility: All substitute parts utilize the 4-SMD Gull Wing surface mount package, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can EL815(S)(TD) directly replace EL815(S)(TA)-V in existing designs?

A: Yes. Both parts share identical electrical specifications including 5000Vrms isolation, 600-7500% current transfer ratio, 80mA output current, and 4-SMD Gull Wing package. No circuit modifications are required.

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

A: Both parts maintain identical electrical and mechanical parameters. The designation difference reflects Everlight's internal product coding. Electrical performance, isolation voltage, output current, and package configuration are equivalent.

Q: Are the "-V" suffix variants (such as EL815(S)(TD)-V) functionally equivalent to non-"-V" variants?

A: Yes. All "-V" and non-"-V" variants within the EL815 family maintain identical electrical specifications, isolation ratings, output characteristics, and package dimensions. The suffix designation does not affect electrical performance or compatibility.

Q: Which substitute part has the highest current inventory?

A: EL815(S)(TD) maintains the highest inventory at 1145 pieces, followed by EL815(S1)(TU) at 1139 pieces.

Q: Do all substitute parts meet the same RoHS and moisture sensitivity requirements?

A: Yes. All substitute parts are ROHS3 compliant with MSL Level 1 (Unlimited) rating, matching the original EL815(S)(TA)-V specifications.

Q: Is PCB layout modification required when substituting to an alternative part number?

A: No. All substitute parts use the 4-SMD Gull Wing package with identical pin configuration and footprint. Direct PCB substitution is supported without layout changes.
