Parameter Comparison

Engineering Selection Recommendations

EL827S1(TA) as Direct Substitute:

The EL827S1(TA) is a parametric equivalent to the EL827S(TA). All electrical parameters, mechanical specifications, and compliance certifications are identical. The primary distinction is packaging format: EL827S(TA) is supplied in standard packaging, while EL827S1(TA) is supplied in Tape & Reel (TR) format. Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating.

Selection between these parts depends on procurement requirements and assembly processes. EL827S1(TA) with Tape & Reel packaging is suitable for high-volume automated assembly operations. EL827S(TA) standard packaging is suitable for lower-volume or manual assembly applications.

Both parts are Active status products from Everlight Electronics Co Ltd and are suitable for direct substitution in circuit designs requiring 5000Vrms isolation, 2-channel transistor output optoisolators in 8-SMD surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can EL827S1(TA) replace EL827S(TA) in production?

A: Yes. EL827S1(TA) is a parametric equivalent with identical electrical and mechanical specifications. The only difference is packaging format (Tape & Reel vs. standard packaging). Functional performance in the circuit is equivalent.

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