NL7SZ18DFT2G-L22348 Equivalent & Substitute Parts

Part Overview

The NL7SZ18DFT2G-L22348 is a 1 x 1:2 demultiplexer logic integrated circuit manufactured by onsemi in a 6-TSSOP (SC-88/SOT-363) surface mount package. This component is classified as obsolete, indicating that the original part number with Cut Tape packaging is no longer in active production. Finding equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and system maintenance.

Substitute Part Grouping Explanation

Substitution of the NL7SZ18DFT2G-L22348 is based on strict electrical and mechanical compatibility criteria. The primary substitute is NL7SZ18DFT2G, which maintains identical functional specifications while differing only in packaging format (Tape & Reel versus Cut Tape). Both parts share the same base product number (NL7SZ18), circuit configuration (1 x 1:2 demultiplexer), package type (6-TSSOP/SC-88/SOT-363), electrical ratings, and compliance certifications.

Secondary substitutes from alternative manufacturers (74LVC1G18 series) are functionally equivalent demultiplexers with matching circuit topology, package specifications, voltage supply ranges, output current ratings, and operating temperature ranges. These parts maintain compatibility across all critical electrical and mechanical parameters that define substitutability for this component category.

Key Parameters Determining Substitutability:

• Circuit type and configuration (1 x 1:2 demultiplexer)
• Package type (6-TSSOP/SC-88/SOT-363)
• Voltage supply range (1.65V ~ 5.5V)
• Output current specifications (32mA minimum)
• Operating temperature range (-55°C ~ 125°C)
• RoHS3 compliance status

Engineering Selection Recommendations

Primary Recommendation: NL7SZ18DFT2G

The NL7SZ18DFT2G is the direct functional equivalent of the NL7SZ18DFT2G-L22348. Both parts are manufactured by onsemi and share identical electrical specifications, circuit configuration, and package type. The primary distinction is packaging format: the substitute is supplied in Tape & Reel format rather than Cut Tape. The NL7SZ18DFT2G maintains Active product status, ensuring long-term availability and supply chain continuity. This part is the preferred choice for direct replacement in production environments.

Secondary Recommendations: 74LVC1G18 Series (NXP and Texas Instruments)

The 74LVC1G18 series demultiplexers from NXP (74LVC1G18GV,125; 74LVC1G18GW,125; 74LVC1G18GW-Q100H) and Texas Instruments (SN74LVC1G18DBVR; SN74LVC1G18DCKR) provide functional equivalence across all critical electrical and mechanical parameters. These parts maintain identical circuit topology, package specifications, voltage supply ranges, output current ratings, and operating temperature ranges. All substitute parts carry ROHS3 compliance and MSL 1 ratings, matching the original part's regulatory status. Selection among these alternatives depends on supply chain availability, lead time requirements, and established vendor relationships.

Frequently Asked Questions (FAQ)

Q: Can NL7SZ18DFT2G directly replace NL7SZ18DFT2G-L22348 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape). No circuit modifications or design changes are required for substitution.

Q: What is the significance of the packaging format difference between Cut Tape and Tape & Reel?

A: Cut Tape packaging is used for small-quantity orders and manual assembly processes. Tape & Reel packaging is standard for automated pick-and-place assembly and high-volume production. The component itself is identical; only the delivery format differs. Tape & Reel format typically offers better availability and lower per-unit cost in production quantities.

Q: Are the 74LVC1G18 series parts from NXP and Texas Instruments fully compatible with the NL7SZ18DFT2G-L22348?

A: Yes. All 74LVC1G18 variants maintain identical circuit configuration (1 x 1:2 demultiplexer), package type (6-TSSOP/SC-88/SOT-363), voltage supply range (1.65V ~ 5.5V), output current specifications (32mA), and operating temperature range (-55°C ~ 125°C). These parts are functionally equivalent and can be used as direct substitutes.

Q: Does the obsolete status of NL7SZ18DFT2G-L22348 affect its use in new designs?

A: The obsolete status indicates that the specific Cut Tape variant is no longer manufactured. However, the equivalent NL7SZ18DFT2G (Active status) and alternative 74LVC1G18 series parts are in active production. For new designs, use an active part number to ensure long-term supply availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance status, matching the original part's regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.

Q: Can I use 74LVC1G18GW-Q100H in automotive or high-reliability applications?

A: The 74LVC1G18GW-Q100H designation indicates qualification for automotive temperature ranges. Verify specific application requirements against the detailed datasheet for your intended use case.
