Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TLP570(TP1,F) is determined by alignment across the following critical parameters:

• Manufacturer & Category: Both main and substitute parts must be optoisolators from Toshiba Semiconductor and Storage to ensure design compatibility and supply chain consistency.
• Functional Classification: The substitute must provide optoisolator functionality with compatible output channel configuration.
• Regulatory Compliance: ECCN and HTSUS classifications must match to maintain export and import compliance.
• Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures handling and storage compatibility without additional environmental controls.

The TLP627M(TP1,E) series qualifies as a direct substitute based on these parameters, with enhanced specifications in isolation voltage and output configuration.

Engineering Selection Recommendations

The TLP627M(TP1,E) is the qualified substitute for the obsolete TLP570(TP1,F) based on the following criteria:

• Product Status Alignment: The TLP627M(TP1,E) maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete TLP570.
• Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, maintaining compliance requirements without modification.
• Moisture Sensitivity Compatibility: Both parts carry MSL 1 (Unlimited) rating, requiring no changes to handling, storage, or assembly processes.
• Functional Equivalence: Both are single-channel optoisolators from Toshiba, providing the required galvanic isolation function.

Selection of the TLP627M(TP1,E) eliminates obsolescence risk while maintaining regulatory and environmental compliance.

Frequently Asked Questions (FAQ)

Q: Why is the TLP570(TP1,F) being replaced? A: The TLP570(TP1,F) is classified as obsolete. The TLP627M(TP1,E) is an active production substitute that maintains functional equivalence and regulatory compliance.

Q: Are the isolation voltage specifications compatible between TLP570 and TLP627M? A: The TLP627M(TP1,E) specifies 5000Vrms isolation voltage. The TLP570(TP1,F) isolation voltage is not provided in the available technical data. Verification against original TLP570 datasheets is required for applications with specific isolation voltage requirements.

Q: What is the difference in packaging between these parts? A: The TLP627M(TP1,E) is specified as Surface Mount in 4-SMD, Gull Wing package with Tape & Reel (TR) packaging. The TLP570(TP1,F) packaging format is not specified in available data.

Q: Are there additional substitute options within the TLP627 series? A: The TLP627M(TP1,E) has documented secondary substitutes: TLP627MF(TP4,E) and TLP627M(D4-TP5,E). These represent alternative package or tape configurations of the same base product number TLP627.

Q: Do both parts share the same regulatory classifications? A: Yes. Both the TLP570(TP1,F) and TLP627M(TP1,E) carry ECCN EAR99 and HTSUS 8541.49.8000 classifications, ensuring no change to export/import compliance requirements.

Q: What is the moisture sensitivity requirement for storage? A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage conditions apply without special environmental controls.
