NC7SP08FHX AND Gate IC Equivalent & Substitute Parts

Part Overview

The NC7SP08FHX is a 1-channel, 2-input AND gate logic IC manufactured by onsemi in a 6-MicroPak2™ package. This part is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The NC7SP08FHX operates across a supply voltage range of 0.9V to 3.6V with minimal quiescent current consumption of 900 nA maximum, suitable for low-power logic applications.

Substitute Part Grouping Explanation

Substitution for the NC7SP08FHX is determined by the following critical parameters: logic function (AND gate), circuit count (1 channel), input count (2 inputs), supply voltage range compatibility, output drive capability, propagation delay performance, and operating temperature range. Package compatibility and surface mount capability are also required for direct board-level substitution.

The NC7SP08L6X represents a parametric equivalent from the same manufacturer series with identical electrical specifications but active product status. The 74AUP1G08GS and SN74AUP1G08DRY2 are similar logic devices from alternative manufacturers (Nexperia and Texas Instruments respectively) that meet the core functional requirements with comparable or superior electrical performance characteristics.

Engineering Selection Recommendations

The NC7SP08L6X is the primary substitute for the NC7SP08FHX. Both parts are from the onsemi 7SP series with identical electrical specifications and the same 6-UFDFN package footprint. The NC7SP08L6X maintains active product status and ROHS3 compliance, providing direct compatibility for board-level replacement without design modification.

The 74AUP1G08GS (Nexperia) and SN74AUP1G08DRY2 (Texas Instruments) are alternative substitutes from the 74AUP logic family. These parts offer superior electrical performance with lower quiescent current (500 nA vs. 900 nA), higher output drive capability (4mA vs. 2.6mA), and faster propagation delay (6.2ns vs. 9.2ns). Both maintain ROHS3 compliance and active product status. The 74AUP1G08GS supports extended operating temperature to 125°C. Package footprints differ slightly (6-XFDFN for Nexperia, 6-UFDFN for Texas Instruments), requiring PCB layout verification before implementation.

Frequently Asked Questions (FAQ)

Q: Can the NC7SP08L6X directly replace the NC7SP08FHX without PCB modifications?

A: Yes. The NC7SP08L6X is a parametric equivalent with identical electrical specifications and the same 6-UFDFN package footprint. No design changes are required for direct substitution.

Q: What are the key differences between the onsemi 7SP series and the 74AUP series substitutes?

A: The 74AUP series (Nexperia and Texas Instruments) offers improved performance characteristics: lower quiescent current consumption (500 nA vs. 900 nA), higher output drive capability (4mA vs. 2.6mA), and faster propagation delay (6.2ns vs. 9.2ns). All parts maintain the same logic function and input/output specifications.

Q: Are package footprints compatible between all substitute options?

A: The NC7SP08FHX and NC7SP08L6X use the 6-UFDFN package. The 74AUP1G08GS uses 6-XFDFN, and the SN74AUP1G08DRY2 uses 6-UFDFN. PCB layout verification is required when switching between different package types.

Q: Do all substitute parts meet RoHS and REACH compliance requirements?

A: Yes. All listed substitute parts (NC7SP08L6X, 74AUP1G08GS, and SN74AUP1G08DRY2) are ROHS3 compliant and REACH unaffected, matching the compliance status of the NC7SP08FHX.

Q: What is the operating temperature range difference between substitutes?

A: The NC7SP08FHX, NC7SP08L6X, and SN74AUP1G08DRY2 operate from -40°C to 85°C. The 74AUP1G08GS extends the upper limit to 125°C, providing broader thermal operating capability for high-temperature applications.

Q: Which substitute offers the best performance improvement?

A: The 74AUP1G08GS and SN74AUP1G08DRY2 both provide measurable performance gains: 33% reduction in quiescent current, 54% increase in output drive capability, and 33% faster propagation delay compared to the NC7SP08FHX.
