Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL852S(TA)(D)-V is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Current Transfer Ratio Range: 1000% to 15000% @ 1mA (mandatory match)
• Output Type: Darlington (mandatory match)
• Maximum Output Voltage: 350V (mandatory match)
• Maximum Output Current: 150mA per channel (mandatory match)
• Vce Saturation: 1.2V maximum (mandatory match)
• Operating Temperature Range: -55°C to 100°C (mandatory match)
• Package Configuration: 4-SMD, Gull Wing (mandatory match)
• Input Type: DC (mandatory match)
• RoHS Compliance: ROHS3 Compliant (mandatory match)

All identified substitute parts meet these criteria without exception. Substitution is based on parametric equivalence within the EL852 series from Everlight Electronics Co Ltd.

Engineering Selection Recommendations

Primary Recommendation: EL852S1(TA)

The EL852S1(TA) is the preferred substitute for the discontinued EL852S(TA)(D)-V. This part maintains complete parametric equivalence across all critical electrical and mechanical specifications. The EL852S1(TA) is currently active in production with the highest inventory availability (22,700 pieces), ensuring supply chain continuity. Packaging is Tape & Reel (TR), suitable for automated assembly processes. ROHS3 compliance and MSL 1 rating are maintained.

Secondary Recommendation: EL852S(TA)

The EL852S(TA) provides identical parametric performance and is also in active production status with substantial inventory (16,900 pieces). This variant is also supplied in Tape & Reel packaging and maintains all compliance certifications.

Tertiary Recommendation: EL852(S)(TU)(D)-V

The EL852(S)(TU)(D)-V meets all parametric requirements and is active in production. Inventory availability is lower (923 pieces) compared to the primary and secondary recommendations. This variant maintains the same electrical specifications and compliance status.

All three substitute parts are direct functional replacements with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can EL852S1(TA) be used as a direct replacement for EL852S(TA)(D)-V in existing designs?

A: Yes. The EL852S1(TA) is parametrically equivalent across all critical specifications including isolation voltage (5000Vrms), current transfer ratio (1000% to 15000% @ 1mA), output type (Darlington), maximum output voltage (350V), maximum output current (150mA), and operating temperature range (-55°C to 100°C). The 4-SMD, Gull Wing package is identical. No circuit modifications are required.

Q: What is the difference between EL852S(TA) and EL852S1(TA)?

A: Both parts are parametrically identical in electrical performance and package configuration. The primary difference is the part number designation within the EL852 series. Both are active in production and ROHS3 compliant. Selection between these two can be based on inventory availability and supplier preference.

Q: Why is the original EL852S(TA)(D)-V discontinued?

A: The EL852S(TA)(D)-V is discontinued at DiGi Electronics. However, parametrically equivalent active alternatives from the same manufacturer (Everlight Electronics Co Ltd) are available. The substitute parts maintain identical specifications and are suitable for direct replacement.

Q: Are there packaging differences between the substitute parts?

A: The EL852S(TA)(D)-V original packaging is not specified in the provided data. The substitute parts EL852S(TA) and EL852S1(TA) are supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly. The EL852(S)(TU)(D)-V packaging is also not specified but maintains the same 4-SMD, Gull Wing case configuration.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All identified substitute parts (EL852(S)(TU)(D)-V, EL852S(TA), and EL852S1(TA)) are ROHS3 compliant. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Q: What is the current transfer ratio specification, and how does it affect substitution?

A: The current transfer ratio range is 1000% to 15000% @ 1mA for all parts. This specification defines the ratio of output current to input current and is critical for circuit design. All substitute parts maintain this identical range, ensuring equivalent performance in isolation and switching applications.

Q: Can EL852(S)(TU)(D)-V be used interchangeably with EL852S1(TA)?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The primary consideration is inventory availability and packaging format. EL852S1(TA) has higher inventory (22,700 pieces) compared to EL852(S)(TU)(D)-V (923 pieces).
