EL827S(TB)-V Optoisolator Equivalent & Substitute Parts

Part Overview

The EL827S(TB)-V is a 2-channel optoisolator with transistor output manufactured by Everlight Electronics Co Ltd. This component provides 5000Vrms isolation voltage and is designed for applications requiring galvanic isolation between input and output circuits. The part is currently in active production status with 935 units available in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to packaging availability, inventory constraints, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the EL827S(TB)-V is determined by strict equivalence across all critical electrical parameters. The substitute part EL827S1(TA) maintains identical specifications for isolation voltage, channel count, current transfer ratio range, output voltage rating, output current per channel, saturation voltage, and operating temperature range. Both parts share the same base product number (EL827), identical package type (8-SMD, Gull Wing), and equivalent mounting technology (Surface Mount).

The primary difference between these parts is packaging format: EL827S(TB)-V is supplied in tube packaging, while EL827S1(TA) is supplied in Tape & Reel (TR) format. This distinction affects inventory management and automated assembly processes but does not alter electrical or mechanical compatibility. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating identical moisture handling requirements.

Substitution is valid when the following parameters are maintained:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 2
• Output Type: Transistor
• Current Transfer Ratio: 50% to 600% @ 5mA
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Package / Case: 8-SMD, Gull Wing
• Operating Temperature: -55°C ~ 110°C

Parameter Comparison

Engineering Selection Recommendations

Both EL827S(TB)-V and EL827S1(TA) are active production components manufactured by Everlight Electronics Co Ltd and are fully ROHS3 compliant. Selection between these parts should be based on packaging and supply requirements rather than electrical performance, as all functional parameters are identical.

The EL827S(TB)-V in tube packaging is suitable for manual assembly, prototyping, and low-volume production environments. The EL827S1(TA) in Tape & Reel format is optimized for automated pick-and-place assembly and high-volume manufacturing operations. Both parts carry identical moisture sensitivity ratings (MSL 1 - Unlimited) and require equivalent handling procedures.

Component selection should account for assembly process requirements, inventory availability, and supply chain lead times. The higher inventory level of EL827S1(TA) (24620 units) compared to EL827S(TB)-V (935 units) may influence procurement decisions for applications with extended production schedules.

Frequently Asked Questions (FAQ)

Q: Are EL827S(TB)-V and EL827S1(TA) electrically interchangeable?

A: Yes. Both parts are manufactured by Everlight Electronics Co Ltd and share identical electrical specifications including isolation voltage (5000Vrms), channel count (2), current transfer ratio (50% to 600% @ 5mA), output voltage rating (80V max), output current (50mA per channel), and operating temperature range (-55°C to 110°C).

Q: What is the difference between tube and Tape & Reel packaging?

A: Tube packaging (TB) is used for manual handling and lower-volume applications. Tape & Reel (TR) packaging is designed for automated assembly equipment and high-volume production. The components themselves are identical; only the delivery format differs.

Q: Can I use EL827S1(TA) in place of EL827S(TB)-V in my PCB assembly?

A: Yes, provided your assembly process supports Tape & Reel format. The 8-SMD, Gull Wing package is identical for both parts, and all electrical parameters match exactly. Verify that your pick-and-place equipment is compatible with TR packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both EL827S(TB)-V and EL827S1(TA) are ROHS3 compliant and carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Which part should I select for new designs?

A: Selection depends on your manufacturing process. For automated assembly, EL827S1(TA) in Tape & Reel format is standard. For manual assembly or prototyping, EL827S(TB)-V in tube packaging is appropriate. Both are active production parts with equivalent performance.

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited), meaning they have no moisture sensitivity restrictions and do not require special dry-pack storage or baking procedures prior to assembly.
