Engineering Selection Recommendations

Active Product Alternatives (Recommended for New Designs):

The 74LVC1G07GW,125 and 74LVC1G07GW-Q100H from Nexperia USA Inc. provide direct functional equivalence with matching 32mA output current and identical supply voltage range. Both maintain ROHS3 compliance and MSL-1 moisture sensitivity rating. The 74LVC1G07GW-Q100H variant includes AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade reliability. The 74LVC1G07SE-7 from Diodes Incorporated offers equivalent electrical performance with SOT-353 package designation and active product status.

The NL17SZ07DFT2G from onsemi provides functional substitution with reduced output current (24mA versus 32mA) and maintains the full -55°C to 125°C operating temperature range. This part is suitable for applications where the lower output current specification is acceptable.

The TC7SZ07FU,LJ(CT from Toshiba Semiconductor and Storage delivers matching 32mA output current and supply voltage specifications with active product status, though operating temperature is limited to -40°C to 125°C.

Obsolete Part References:

The NL17SZ07DFT2G-F22038 and NLV17SZ07DFT2G are listed as obsolete and should not be selected for new designs. These parts are included for reference only in legacy system support scenarios.

Compliance and Certification:

All active substitute parts maintain ROHS3 compliance and MSL-1 moisture sensitivity rating, matching the original SN74LVC1G07MDCKREP specification. The 74LVC1G07GW-Q100H includes AEC-Q100 qualification for automotive applications. All parts are REACH Unaffected and carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the NL17SZ07DFT2G be used as a direct replacement for the SN74LVC1G07MDCKREP?

A: The NL17SZ07DFT2G is functionally equivalent with one electrical difference: output current is specified at 24mA versus the original 32mA. This part is suitable for applications where the lower output current meets design requirements. Both parts maintain identical supply voltage range (1.65V ~ 5.5V) and operating temperature range (-55°C ~ 125°C).

Q: What is the difference between the 74LVC1G07GW,125 and 74LVC1G07GW-Q100H?

A: Both parts are manufactured by Nexperia USA Inc. with identical electrical specifications (32mA output current, 1.65V ~ 5.5V supply voltage). The primary difference is that 74LVC1G07GW-Q100H includes AEC-Q100 automotive qualification and is supplied in Tape & Reel packaging, while 74LVC1G07GW,125 is supplied in Cut Tape & Digi-Reel packaging. Operating temperature for both is -40°C ~ 125°C.

Q: Are package designations SC-70-5, SC-88A, SC-74A, 5-TSSOP, and SOT-353 interchangeable?

A: These designations refer to equivalent 5-pin surface mount packages with identical pin configurations and footprints. SC-70-5, SC-88A, 5-TSSOP, and SOT-353 are functionally interchangeable package types. SC-74A is a similar package variant. Verify PCB footprint compatibility with your design before selection.

Q: Why are NL17SZ07DFT2G-F22038 and NLV17SZ07DFT2G listed as obsolete?

A: These parts are marked as obsolete by their manufacturer (onsemi) and are no longer in active production. They are included in this reference for legacy system support only. For new designs, select from the active product alternatives listed in the Engineering Selection Recommendations section.

Q: Which substitute part has the widest operating temperature range?

A: The SN74LVC1G07MDCKREP, NL17SZ07DFT2G, NL17SZ07DFT2G-F22038, and NLV17SZ07DFT2G all operate across -55°C ~ 125°C. All other active alternatives operate across -40°C ~ 125°C. Select the -55°C variant if your application requires extended low-temperature operation.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and MSL-1 moisture sensitivity rating, matching the original SN74LVC1G07MDCKREP specification.
