Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLP627MF(E are identified as parametric equivalents within the TLP627 base product family. All substitute parts maintain identical electrical specifications across the following critical parameters:

• Voltage - Isolation: 5000Vrms
• Current Transfer Ratio (Min): 1000% @ 1mA
• Output Type: Darlington
• Voltage - Output (Max): 300V
• Current - Output / Channel: 150mA
• Turn On / Turn Off Time (Typ): 110µs, 30µs
• Operating Temperature: -55°C ~ 110°C
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitution is valid when all electrical performance parameters and mechanical package specifications match the main part. Variations in part number suffixes (such as LF4, LF5, D4-LF5) indicate different manufacturing process nodes or lead-free designations but do not alter functional equivalence.

Engineering Selection Recommendations

All substitute parts listed are direct parametric equivalents to the TLP627MF(E and are suitable for component selection in applications requiring this optoisolator specification. Selection among equivalent parts may be based on:

• Inventory availability: TLP627MF(E (1208 units), TLP627MF(LF4,E (1121 units), TLP627M(LF5,E (1118 units), TLP627M(D4-LF5,E (1026 units)
• Product status: All parts are in active production
• Compliance certifications: All parts maintain ROHS3 compliance and REACH unaffected status
• Moisture sensitivity: All parts carry MSL Level 1 (unlimited floor life)

No additional testing or qualification is required when substituting between these parts, as all electrical performance and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can TLP627M(LF5,E be used as a direct replacement for TLP627MF(E?

A: Yes. Both parts share identical electrical specifications including 5000Vrms isolation voltage, 1000% current transfer ratio, 300V maximum output voltage, and 150mA output current. The 4-SMD Gull Wing package and operating temperature range are also identical. Substitution is valid for any application using the TLP627MF(E.

Q: What do the suffix designations (LF4, LF5, D4-LF5) indicate?

A: These suffixes represent different manufacturing process nodes and lead-free designations within the TLP627 family. They do not affect electrical performance or functional compatibility. All variants maintain the same parametric specifications.

Q: Are there any compliance or certification differences between the substitute parts?

A: No. All parts listed are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL Level 1). Regulatory compliance is consistent across all substitute options.

Q: Which substitute part should be selected if inventory is a primary concern?

A: TLP627MF(E has the highest inventory level at 1208 units. If this part is unavailable, TLP627MF(LF4,E (1121 units) and TLP627M(LF5,E (1118 units) offer comparable stock levels.

Q: Is the 4-SMD Gull Wing package identical across all substitute parts?

A: Yes. All parts use the same 4-SMD Gull Wing surface mount package with identical mechanical specifications, ensuring compatibility with existing PCB layouts and assembly processes.
