Substitute Part Grouping Explanation

Substitution of the EL3H7(B)(TB)-VG is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Isolation: 3750Vrms
• Number of Channels: 1
• Current Transfer Ratio range: 130% to 260% @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Operating Temperature range: -55°C ~ 110°C
• Input Type: DC

Mechanical Equivalence Criteria:

• Package / Case: 4-SOIC (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 4-SSOP

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part EL3H7(B)(TA)-VG maintains identical electrical and mechanical specifications. The substitution difference is limited to packaging format: the main part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) & Digi-Reel® packaging. Both formats contain the same component in the same physical package configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the EL3H7(B)(TB)-VG and EL3H7(B)(TA)-VG are Active status components manufactured by Everlight Electronics Co Ltd with ROHS3 compliance and MSL Level 1 rating. Selection between these parts is based on packaging format requirements:

EL3H7(B)(TB)-VG is specified when Tape & Reel (TR) packaging is required for automated assembly processes or high-volume production environments.

EL3H7(B)(TA)-VG is specified when Cut Tape (CT) & Digi-Reel® packaging is required for lower-volume applications, manual assembly, or when component-level flexibility is prioritized.

Both parts are electrically and mechanically interchangeable. The selection criterion is packaging format only. No electrical re-qualification or design modification is necessary when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are EL3H7(B)(TB)-VG and EL3H7(B)(TA)-VG electrically identical?

A: Yes. Both parts have identical electrical specifications including isolation voltage (3750Vrms), current transfer ratio (130%-260% @ 5mA), output voltage (80V max), output current (50mA), and operating temperature range (-55°C ~ 110°C).

Q: What is the difference between these two part numbers?

A: The only difference is packaging format. EL3H7(B)(TB)-VG uses Tape & Reel (TR) packaging, while EL3H7(B)(TA)-VG uses Cut Tape (CT) & Digi-Reel® packaging. The physical component and pin configuration are identical.

Q: Can I substitute EL3H7(B)(TA)-VG for EL3H7(B)(TB)-VG in my design?

A: Yes, provided your assembly process can accommodate Cut Tape (CT) & Digi-Reel® packaging format. No circuit design changes are required.

Q: Are both parts ROHS3 compliant?

A: Yes. Both EL3H7(B)(TB)-VG and EL3H7(B)(TA)-VG are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which packaging format should I specify for high-volume production?

A: Tape & Reel (TR) format, represented by EL3H7(B)(TB)-VG, is standard for automated pick-and-place assembly in high-volume manufacturing.

Q: Which packaging format is suitable for lower-volume or prototype applications?

A: Cut Tape (CT) & Digi-Reel® format, represented by EL3H7(B)(TA)-VG, provides component-level flexibility for lower-volume builds and prototyping.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts have identical MSL Level 1 rating, requiring the same moisture control and storage conditions.

Q: Is the 4-SSOP package footprint identical for both parts?

A: Yes. Both parts use the 4-SOIC (0.173", 4.40mm Width) package with identical pin configuration and PCB footprint.
