Substitute parts are grouped into three categories based on their relationship to the main part:

MFR Recommended Substitutes maintain identical or superior electrical specifications while differing only in packaging format (Tape & Reel vs. Tube) or product status (Active vs. Last Time Buy). These include CD74HC107M96 and CD74HC107M from Texas Instruments, and 74HC107D,653 from Nexperia USA Inc.

Direct Manufacturer Alternatives are sourced from different manufacturers but maintain full electrical and mechanical compatibility. The 74HC107D-Q100J from Nexperia USA Inc. qualifies as a direct alternative with automotive-grade qualification (AEC-Q100).

Parametric Equivalents include the MC74HC73ADG and MC74HC73ADR2G from onsemi, and CD74HC73M from Texas Instruments. These devices share the same functional architecture (dual JK-type flip-flops with complementary outputs) and identical package geometry, though they operate under the 74HC73 base product designation rather than 74HC107.

Frequently Asked Questions (FAQ)

Q: Can I use MC74HC73ADR2G or MC74HC73ADG as a direct replacement for CD74HC107MG4?

A: Yes, with full electrical and mechanical compatibility. Both parts are parametric equivalents sharing identical JK-type flip-flop architecture, complementary output configuration, negative edge trigger mechanism, 14-SOIC package geometry, and supply voltage range. The primary difference is the base product designation (74HC73 vs. 74HC107), which does not affect functional operation. Clock frequency and propagation delay specifications differ slightly but remain within compatible operating parameters.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for lower-volume applications and manual assembly processes. Tape & Reel packaging is optimized for high-volume automated manufacturing and pick-and-place assembly equipment. Both formats contain identical die and electrical specifications. Selection depends on production volume and assembly methodology rather than electrical performance.

Q: Why is the 74HC107D-Q100J listed as a substitute if it has a different operating temperature range?

A: The 74HC107D-Q100J operates from -40°C to 125°C, compared to the CD74HC107MG4 range of -55°C to 125°C. This represents a narrower low-temperature specification. The part is listed as a direct alternative because it maintains all critical electrical parameters, identical package geometry, and adds automotive-grade qualification (AEC-Q100). Selection of this part is appropriate for applications operating within the -40°C to 125°C range or for designs requiring automotive qualification.

Q: What does "Last Time Buy" status mean for the CD74HC107MG4?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this specific part number. New orders may be accepted for a limited period, but production will cease. This status makes identification of active substitutes essential for long-term design support. CD74HC107M96 and 74HC107D,653 are recommended alternatives with Active product status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental compliance profile of the CD74HC107MG4. This ensures compatibility with regulatory requirements across all listed alternatives.

Q: How do clock frequency differences affect substitution?

A: Clock frequency specifications (35 MHz, 60 MHz, 85 MHz) represent maximum operating frequencies. A substitute part with equal or higher clock frequency is electrically compatible. For example, the 74HC107D-Q100J at 85 MHz can replace the CD74HC107MG4 at 60 MHz. Conversely, the MC74HC73ADR2G at 35 MHz is also compatible because it meets or exceeds the timing requirements of typical 74HC107 applications. Actual circuit performance depends on design-specific timing margins.

Q: What inventory considerations should guide my selection?

A: MC74HC73ADR2G offers the highest inventory availability at 10,200 pieces in Tape & Reel format. CD74HC107M96 provides 3,136 pieces in Tape & Reel format with identical electrical specifications to the original part. 74HC107D,653 offers 6,286 pieces in Tape & Reel format with improved timing performance. Selection should balance immediate availability requirements against long-term supply chain stability and product status (Active vs. Last Time Buy).
