Substitute Part Grouping Explanation

Substitute parts for the EL827S(TA)-V are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criterion is the EL827S1(TA), which shares the same base product number (EL827) and maintains identical specifications across all critical parameters that define functional interchangeability.

The substitution logic is based on the following key parameters:

• Isolation Voltage: 5000Vrms (identical)
• Number of Channels: 2 (identical)
• Output Type: Transistor (identical)
• Current Transfer Ratio Range: 50% to 600% @ 5mA (identical)
• Maximum Output Voltage: 80V (identical)
• Output Current per Channel: 50mA (identical)
• Vce Saturation: 200mV maximum (identical)
• Operating Temperature Range: -55°C ~ 110°C (identical)
• Package Configuration: 8-SMD, Gull Wing (identical)
• Mounting Type: Surface Mount (identical)
• RoHS Compliance: ROHS3 Compliant (identical)

The EL827S1(TA) differs from the main part only in packaging format (Tape & Reel versus standard packaging) and inventory availability, with no electrical or mechanical parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The EL827S1(TA) is a direct functional equivalent to the EL827S(TA)-V for all circuit design and application purposes. Both parts maintain Active product status and are ROHS3 compliant with identical electrical performance specifications.

Selection between these parts should be based on the following factors:

Packaging Requirements: The EL827S(TA)-V is supplied in standard packaging, while the EL827S1(TA) is supplied in Tape & Reel format. Tape & Reel packaging is standard for automated assembly processes and high-volume production environments.

Inventory Availability: The EL827S1(TA) maintains significantly higher inventory levels (24620 units) compared to the EL827S(TA)-V (866 units), making it the preferred choice for applications with extended lead time requirements or high-volume procurement needs.

Compliance and Certification: Both parts carry identical RoHS3 compliance status and MSL rating of 1 (Unlimited), indicating equivalent environmental and moisture handling requirements.

Electrical Performance: No electrical parameter differences exist between the two parts. Both deliver 5000Vrms isolation, 2-channel transistor output configuration, and identical current transfer ratio specifications across the full operating temperature range of -55°C to 110°C.

Frequently Asked Questions (FAQ)

Q: Can EL827S1(TA) be used as a direct replacement for EL827S(TA)-V in existing designs?

A: Yes. The EL827S1(TA) is electrically and mechanically identical to the EL827S(TA)-V. All electrical parameters, isolation voltage, channel configuration, output characteristics, and operating temperature range are equivalent. The only difference is the packaging format (Tape & Reel versus standard packaging).

Q: What is the difference between the EL827S(TA)-V and EL827S1(TA)?

A: The parts are identical in all electrical and mechanical specifications. The primary difference is packaging format: EL827S(TA)-V uses standard packaging while EL827S1(TA) uses Tape & Reel format. Tape & Reel packaging is optimized for automated assembly processes.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the EL827S(TA)-V and EL827S1(TA) operate across the identical temperature range of -55°C to 110°C, making them suitable for the same thermal environments.

Q: Which part should be selected for new designs?

A: For new designs, the EL827S1(TA) is recommended due to higher inventory availability and standard Tape & Reel packaging format, which is compatible with modern automated assembly equipment. However, either part delivers identical electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EL827S(TA)-V and EL827S1(TA) are ROHS3 compliant with MSL rating of 1 (Unlimited), indicating identical environmental compliance and moisture sensitivity characteristics.

Q: What is the isolation voltage specification for these parts?

A: Both parts provide 5000Vrms isolation voltage, suitable for applications requiring high-voltage galvanic isolation between input and output circuits.

Q: Can these parts be used interchangeably in automated assembly?

A: The EL827S1(TA) in Tape & Reel format is optimized for automated assembly processes. The EL827S(TA)-V in standard packaging may require manual handling or custom feeder setup depending on assembly equipment configuration. Both deliver identical electrical performance once assembled.
