Substitute Part Grouping Explanation

Substitution eligibility for the EL3H7(C)(TB)-VG is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part EL3H7(C)(TA)-VG qualifies as a parametric equivalent based on the following criteria:

Isolation Voltage: Both parts maintain 3750Vrms isolation rating, meeting identical safety and regulatory requirements.

Channel Configuration: Single channel architecture is preserved across both parts.

Current Transfer Ratio: Minimum 200% and maximum 400% specifications at 5mA input current are identical.

Output Characteristics: Maximum output voltage of 80V and per-channel output current of 50mA are matched. Vce saturation maximum of 200mV is equivalent.

Switching Performance: Rise and fall times of 5µs and 3µs respectively are identical.

Temperature Range: Operating temperature specification of -55°C to 110°C is maintained.

Package Specification: Both parts use 4-SOIC (0.173", 4.40mm Width) surface mount package with 4-SSOP supplier device package designation.

Compliance: Both parts carry ROHS3 compliance and MSL Level 1 rating.

The only differentiating factor is packaging format designation (TB versus TA), which represents different tape and reel configurations from the same manufacturer without affecting electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both EL3H7(C)(TB)-VG and EL3H7(C)(TA)-VG are Active status products from Everlight Electronics Co Ltd with full ROHS3 compliance and MSL Level 1 rating. Selection between these parts is based on packaging format requirements and supply availability rather than electrical or mechanical performance differences.

The EL3H7(C)(TB)-VG designation indicates TB tape and reel configuration with current inventory of 794 pieces. The EL3H7(C)(TA)-VG designation indicates TA tape and reel configuration with current inventory of 2100 pieces. Both parts are identical in all electrical specifications, thermal performance, and mechanical dimensions.

Component selection should prioritize availability and lead time requirements. The TA variant offers higher current inventory levels. Both parts meet identical regulatory and compliance requirements for applications requiring 3750Vrms isolation, single-channel transistor output optoisolation, and surface mount 4-SOIC packaging.

Frequently Asked Questions (FAQ)

Q: Can EL3H7(C)(TA)-VG be used as a direct replacement for EL3H7(C)(TB)-VG?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output characteristics, isolation voltage, current transfer ratios, switching times, temperature range, and package dimensions. The only difference is the tape and reel configuration (TA versus TB), which does not affect circuit performance or PCB assembly compatibility.

Q: What does the TB and TA designation represent?

A: TB and TA represent different tape and reel packaging formats from Everlight Electronics Co Ltd. Both formats contain the same component in 4-SOIC surface mount package. The designation affects only the physical reel configuration and does not impact electrical performance or mechanical fit on PCB assemblies.

Q: Are both parts suitable for high-voltage isolation applications?

A: Yes. Both EL3H7(C)(TB)-VG and EL3H7(C)(TA)-VG provide 3750Vrms isolation rating, meeting identical safety and regulatory requirements for galvanic isolation in industrial and power management applications.

Q: Do both parts have the same temperature operating range?

A: Yes. Both parts operate across -55°C to 110°C temperature range with identical thermal specifications and performance characteristics.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry ROHS3 compliance, MSL Level 1 rating, EAR99 ECCN classification, and identical HTSUS coding. Regulatory and compliance status is equivalent.

Q: What is the significance of the 4-SSOP supplier device package designation?

A: The 4-SSOP designation indicates the physical component package format used by Everlight Electronics. Both parts use this same package format, ensuring identical PCB footprint, lead spacing, and assembly compatibility regardless of tape and reel configuration.

Q: Can these parts be used interchangeably in production?

A: Yes. From an engineering perspective, EL3H7(C)(TB)-VG and EL3H7(C)(TA)-VG are fully interchangeable. Selection between them should be based on supply chain availability, lead time, and tape and reel format requirements for your specific manufacturing process.
