Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP627-2(LF1,F) is determined by the following critical parameters:

• Base Product Series: All substitutes must belong to the TLP627 family to ensure functional equivalence
• Number of Channels: Single-channel configuration required
• Isolation Voltage: Minimum 5000Vrms isolation rating
• Output Type: Darlington output configuration for compatible switching characteristics
• Mounting Type: Surface mount compatibility
• Package Type: 4-SMD form factor with gull wing leads
• Product Status: Active status ensures ongoing availability and support
• Compliance: ECCN EAR99 and HTSUS 8541.49.8000 classification maintained

The TLP627M(LF1,E) variant meets all substitution criteria as an active product within the same base series with identical electrical isolation specifications and mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

The TLP627M(LF1,E) is the direct substitute for the obsolete TLP627-2(LF1,F). Both components share identical electrical specifications including 5000Vrms isolation voltage, 150mA output current capability, and Darlington output configuration. The primary distinction is product status: TLP627M(LF1,E) maintains active production status with confirmed inventory availability of 1086 pieces, whereas TLP627-2(LF1,F) is obsolete with limited remaining stock of 696 pieces.

Both parts maintain identical compliance classifications (ECCN EAR99, HTSUS 8541.49.8000) and moisture sensitivity ratings (MSL 1). The 4-SMD gull wing package and surface mount configuration are identical, ensuring direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can TLP627M(LF1,E) be used as a direct replacement for TLP627-2(LF1,F)?

A: Yes. Both components share identical electrical specifications (5000Vrms isolation, 150mA output current, Darlington output), operating temperature range (-55°C to 110°C), and 4-SMD gull wing package configuration. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The TLP627-2(LF1,F) is obsolete. TLP627M(LF1,E) is an active product with ongoing manufacturing and supply availability.

Q: Are there packaging differences between these parts?

A: No. Both use identical 4-SMD gull wing surface mount packaging. PCB footprints and soldering procedures remain unchanged.

Q: Do compliance and regulatory classifications differ?

A: No. Both parts maintain identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, and both have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What are the key electrical parameters that define substitution eligibility?

A: Isolation voltage (5000Vrms), number of channels (1), output type (Darlington), maximum output voltage (300V), and output current per channel (150mA) must remain constant for functional equivalence.
