Engineering Selection Recommendations

The MAX1759EUB+ is the direct equivalent substitute for the obsolete SIP1759DH-T1-E3. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The MAX1759EUB+ maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring long-term availability and supply chain continuity.

All electrical parameters, thermal specifications, and package dimensions are identical between the two parts. The supplier device package designation differs (10-MSOP versus 10-uMAX/uSOP), but both represent equivalent 10-pin surface mount packages with identical 0.118" (3.00mm) width specifications and compatible PCB footprints.

For applications currently using the SIP1759DH-T1-E3, direct substitution with the MAX1759EUB+ is supported without circuit modification or re-qualification, provided the application operates within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can the MAX1759EUB+ directly replace the SIP1759DH-T1-E3 without PCB modifications?

A: Yes. Both parts share identical electrical specifications, operating temperature ranges, and package footprints (10-TFSOP/10-MSOP, 0.118" width). The pin configuration and functional behavior are equivalent, allowing direct substitution on existing PCB designs.

Q: What is the difference between 10-MSOP and 10-uMAX/uSOP packaging?

A: Both designations refer to 10-pin surface mount packages with 0.118" (3.00mm) width. The different naming conventions reflect manufacturer terminology; the physical dimensions and PCB footprints are compatible.

Q: Why is the SIP1759DH-T1-E3 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Vishay Siliconix. The MAX1759EUB+ provides equivalent functionality and is actively produced by Analog Devices Inc./Maxim Integrated.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory compliance is maintained with the substitute part.

Q: What output voltage configurations are available with the MAX1759EUB+?

A: The MAX1759EUB+ supports adjustable output voltage or fixed configurations at 2.5V or 3.3V, with maximum output voltage capability to 5.5V. Input voltage range is 1.6V to 5.5V, matching the original SIP1759DH-T1-E3 specifications.

Q: Is the 100mA output current rating the same for both parts?

A: Yes. Both the SIP1759DH-T1-E3 and MAX1759EUB+ are rated for 100mA maximum output current across the specified input and output voltage ranges.
