Substitute Part Grouping Explanation

Substitution of the 74LVC2G38GD,125 is determined by strict equivalence across the following critical parameters: logic type (NAND Gate), circuit count (2 channels), input count (2 per channel), open drain feature, supply voltage range (1.65V ~ 5.5V), quiescent current (4 µA maximum), output current capability (32mA), input logic thresholds, propagation delay (3.3ns @ 5V, 50pF), operating temperature range (-40°C ~ 125°C), and surface mount configuration.

Substitute parts are grouped into two categories:

Direct Package Substitutes: Parts maintaining identical or compatible package footprints (8-XSON variants) with all electrical parameters matching the main part.

Functional Equivalents with Package Variation: Parts with identical electrical specifications but different package types (8-VSSOP), suitable for applications where package footprint flexibility exists.

All substitute parts listed maintain the 74LVC base product number designation and are certified to the same compliance standards (ROHS3, REACH Unaffected, EAR99).

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the 74LVC2G38GD,125, the following selection criteria apply based on product status and compliance:

Active Product Alternatives: The 74LVC2G38DC,125, 74LVC2G38GN,115, 74LVC2G38GS,115, and 74LVC2G38GT,115 are all classified as active products, ensuring long-term availability and supply chain continuity. These parts are preferred for new designs and ongoing production requirements.

Package Considerations: The 74LVC2G38DC,125 offers a functional equivalent with an 8-VFSOP package footprint, suitable for applications where the original 8-XFDFN footprint cannot be accommodated. The 74LVC2G38GS,115 and 74LVC2G38GF,115 maintain the 8-XFDFN package in different physical dimensions (1.35x1 versus 2x3), allowing flexibility in PCB layout constraints.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and REACH unaffected status where specified, ensuring regulatory alignment with the original component.

Inventory Availability: Active products demonstrate higher inventory levels, with 74LVC2G38GT,115 offering 60,400 pieces and 74LVC2G38GN,115 offering 5,911 pieces in stock, compared to the obsolete 74LVC2G38GD,125 with 1,066 pieces remaining.

Frequently Asked Questions (FAQ)

Q: Can the 74LVC2G38DC,125 be used as a direct replacement for the 74LVC2G38GD,125?

A: The 74LVC2G38DC,125 is electrically equivalent across all specified parameters. However, it uses an 8-VSSOP package instead of the 8-XFDFN package. PCB layout modifications are required to accommodate the different footprint. Electrical functionality and performance are identical.

Q: What is the difference between the 74LVC2G38GS,115 and 74LVC2G38GF,115?

A: Both parts are electrically identical NAND gate ICs with 2 channels and 2 inputs per channel in 8-XSON packages. The primary difference is packaging format: 74LVC2G38GS,115 is supplied in Tape & Reel (TR) format with 5,730 pieces in stock, while 74LVC2G38GF,115 is supplied in Cut Tape (CT) & Digi-Reel format with 1,206 pieces in stock. The physical package dimensions differ slightly (1.35x1 for both versus 2x3 for the original).

Q: Are all substitute parts ROHS3 compliant?

A: ROHS3 compliance is explicitly specified for 74LVC2G38GD,125, 74LVC2G38GF,115, and 74LVC2G38GS,115. Compliance information is not provided in the available data for 74LVC2G38DC,125, 74LVC2G38GN,115, and 74LVC2G38GT,115. Verify compliance requirements with the component supplier for these parts.

Q: Which substitute part offers the best long-term availability?

A: The 74LVC2G38GT,115 is classified as an active product with the highest inventory level at 60,400 pieces, providing the strongest supply chain assurance for ongoing production requirements.

Q: Can I use 74LVC2G38GN,115 or 74LVC2G38GT,115 as substitutes if package specifications are not critical?

A: Both parts are electrically equivalent to the main part and classified as active products. However, complete package and detailed specification information is not provided in the available data for these parts. Obtain full datasheets from the manufacturer before finalizing design decisions.

Q: What is the moisture sensitivity level for all substitute parts?

A: Moisture Sensitivity Level 1 (Unlimited) is specified for 74LVC2G38GD,125, 74LVC2G38GF,115, 74LVC2G38GS,115, 74LVC2G38GN,115, and 74LVC2G38GT,115. This classification indicates no moisture sensitivity restrictions during storage and handling. MSL information is not provided for 74LVC2G38DC,125.
