Frequently Asked Questions (FAQ)

Q: Why is the TLP9148J(PSD-TL,F) being phased out?

A: The TLP9148J(PSD-TL,F) is classified as obsolete by the manufacturer. Toshiba Semiconductor and Storage has designated this component as end-of-life, making the TLX9175J(TPL,F) the active alternative for new designs and ongoing production requirements.

Q: What are the key differences between the TLP9148J(PSD-TL,F) and TLX9175J(TPL,F)?

A: The primary differences are product status (obsolete versus active), output type (unspecified versus MOSFET), isolation voltage (unspecified versus 3750Vrms), and qualification level (unspecified versus AEC-Q101 automotive grade). The substitute provides fully documented electrical and environmental specifications.

Q: Are the packages compatible between these two parts?

A: The TLP9148J(PSD-TL,F) package specifications are not provided in available documentation. The TLX9175J(TPL,F) uses a 6-SOIC (0.173", 4.40mm Width) surface mount package with 4 leads in 6-SOP supplier configuration. Physical compatibility must be verified against the original part's actual package dimensions and pinout.

Q: Can the TLX9175J(TPL,F) be used in all applications where the TLP9148J(PSD-TL,F) was used?

A: Substitution suitability depends on specific application requirements including isolation voltage, output type, temperature range, and package compatibility. The TLX9175J(TPL,F) provides enhanced specifications (3750Vrms isolation, MOSFET output, -55°C to 105°C operation) that support a broad range of applications. Application-specific validation is required to confirm functional equivalence.

Q: What is the inventory status for these components?

A: The TLP9148J(PSD-TL,F) has 736 pieces of new original stock available. The TLX9175J(TPL,F) has 2942 pieces of new original stock available in tape and reel packaging.

Q: Are both components subject to the same export controls?

A: Yes. Both the TLP9148J(PSD-TL,F) and TLX9175J(TPL,F) are classified under ECCN EAR99 and HTSUS code 8541.49.8000, indicating identical export control and tariff treatment.

Q: What certifications does the substitute part carry?

A: The TLX9175J(TPL,F) carries AEC-Q101 automotive qualification and is classified as REACH Unaffected, confirming compliance with automotive reliability standards and European chemical substance regulations.
