Substitute Part Grouping Explanation

Substitution of the TLP627MF(LF2,E is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 5000Vrms (mandatory match)
Number of Channels: 1 channel (mandatory match)
Output Configuration: Darlington output (mandatory match)
Package Type: 4-DIP (0.400", 10.16mm) (mandatory match)
Mounting Technology: Through Hole (mandatory match)
Current Transfer Ratio: 1000% @ 1mA minimum (mandatory match)
Maximum Output Voltage: 300V (mandatory match)
Maximum Output Current: 150mA per channel (mandatory match)
Operating Temperature Range: -55°C ~ 110°C (mandatory match)

The identified substitute parts TLP627MF(D4,E and TLP627MF(D4-F4,E meet all electrical and mechanical parameters identically. Differences exist only in packaging format (Tube vs. standard packaging) and supplier device package designation, which do not affect functional compatibility or circuit performance.

Engineering Selection Recommendations

All three part numbers—TLP627MF(LF2,E, TLP627MF(D4,E, and TLP627MF(D4-F4,E—are manufactured by Toshiba Semiconductor and Storage and maintain active product status. The substitute parts TLP627MF(D4,E and TLP627MF(D4-F4,E carry ROHS3 compliance and REACH Unaffected status certifications, providing additional regulatory assurance for applications requiring environmental compliance documentation.

Selection between these equivalent parts should be based on:

Packaging Format: TLP627MF(D4,E and TLP627MF(D4-F4,E are supplied in Tube packaging, while TLP627MF(LF2,E uses standard packaging
Inventory Availability: TLP627MF(D4,E (1119 units), TLP627MF(D4-F4,E (972 units), and TLP627MF(LF2,E (1011 units) are all in stock
Regulatory Requirements: Applications requiring explicit ROHS3 and REACH documentation should specify TLP627MF(D4,E or TLP627MF(D4-F4,E

All parts are functionally interchangeable in circuit applications without modification to PCB layout, component footprint, or electrical design parameters.

Frequently Asked Questions (FAQ)

Q: Can TLP627MF(D4,E be used as a direct replacement for TLP627MF(LF2,E in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tube vs. standard). No circuit modifications, PCB changes, or design alterations are required.

Q: What is the difference between TLP627MF(D4,E and TLP627MF(D4-F4,E?

A: Both parts are parametrically equivalent with identical electrical specifications and 4-DIP package dimensions. The designation difference reflects supplier device package coding only and does not affect functional performance or compatibility.
