Substitute Part Grouping Explanation

Substitute parts for the SFH615A-2G are identified based on exact matching of the following critical parameters:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 1
• Output Type: Transistor
• Current Transfer Ratio range: 63% to 125% @ 10mA
• Voltage - Output (Max): 70V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 400mV
• Operating Temperature range: -30°C ~ 100°C
• Package / Case: 4-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole

The SFH615A-2XG meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications and mechanical packaging, enabling direct substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can SFH615A-2XG be used as a direct replacement for SFH615A-2G?

A: Yes. The SFH615A-2XG is a parametric equivalent with identical isolation voltage, channel count, output type, current transfer ratio, output voltage, output current, saturation voltage, operating temperature range, and 4-DIP package configuration. Direct substitution is supported without circuit modification.

Q: Are there any differences in package dimensions between these parts?

A: No. Both parts use the same 4-DIP package with dimensions of 0.400" (10.16mm). Through-hole mounting compatibility is identical.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: isolation voltage (5300Vrms), number of channels (1), output type (transistor), current transfer ratio range (63-125% @ 10mA), maximum output voltage (70V), maximum output current (50mA), maximum saturation voltage (400mV), operating temperature range (-30°C to 100°C), and package type (4-DIP through-hole).

Q: Do both parts meet the same compliance standards?

A: Yes. Both SFH615A-2G and SFH615A-2XG are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status.

Q: Which part should be selected based on availability?

A: Selection may be based on inventory requirements. SFH615A-2G has higher current stock (1092 units) compared to SFH615A-2XG (895 units). Both are active products with equivalent performance characteristics.
