MM74C107N Equivalent & Substitute Parts

Part Overview

The MM74C107N is a dual JK-type flip-flop logic integrated circuit manufactured by onsemi, housed in a 14-DIP (0.300", 7.62mm) through-hole package. This device belongs to the 74C logic series and is classified as obsolete. Due to its obsolete status and limited availability from original sources, identifying functionally equivalent substitute components is essential for system redesign, board revision, and long-term supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MM74C107N is determined by the following critical parameters:

• Functional Type: JK-type flip-flop with 2 elements
• Package Compatibility: 14-DIP (0.300", 7.62mm) through-hole form factor
• Logic Family: Modern equivalent logic families (74HCT series) that maintain pin-compatible footprints and functional behavior
• Electrical Interface: Supply voltage and output characteristics suitable for the target application

The CD74HCT73E from Texas Instruments qualifies as a substitute based on matching functional architecture (dual JK-type flip-flop), identical package geometry, and through-hole mounting compatibility. The 74HCT series provides active product status and improved compliance characteristics compared to the obsolete 74C series.

Parameter Comparison

Engineering Selection Recommendations

The CD74HCT73E is the designated substitute for the MM74C107N based on the following engineering criteria:

Product Status & Availability: The MM74C107N is obsolete with no active manufacturing. The CD74HCT73E maintains active product status with confirmed inventory availability (2200 pcs), ensuring long-term supply chain viability.

Compliance & Regulatory: The CD74HCT73E is ROHS3 compliant, addressing modern regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Package & Mechanical Compatibility: Both devices utilize identical 14-DIP (0.300", 7.62mm) through-hole packaging, enabling direct footprint substitution on existing printed circuit boards without layout modification.

Functional Equivalence: Both parts implement dual JK-type flip-flop architecture with 2 elements, maintaining functional compatibility for logic circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT73E be used as a direct replacement for the MM74C107N?

A: Yes, the CD74HCT73E is functionally and mechanically compatible. Both devices share identical 14-DIP package geometry and dual JK-type flip-flop architecture. Verify that your application's supply voltage range (4.5V ~ 5.5V for the CD74HCT73E) matches your system requirements.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and specified electrical parameters. The CD74HCT73E provides documented operating temperature range (-55°C ~ 125°C), supply voltage specifications (4.5V ~ 5.5V), and trigger characteristics (negative edge), whereas the MM74C107N does not include these specifications in available documentation.

Q: Are there any pin-out differences between the MM74C107N and CD74HCT73E?

A: Both devices use 14-DIP through-hole packaging with identical pin counts and footprints. Pin compatibility is maintained for direct board-level substitution.

Q: Does the CD74HCT73E require any circuit modifications?

A: No circuit modifications are required if your application operates within the CD74HCT73E's specified supply voltage range (4.5V ~ 5.5V). Verify that your existing power supply and signal levels are compatible with these specifications.

Q: What is the inventory status of the CD74HCT73E?

A: The CD74HCT73E is actively manufactured by Texas Instruments with 2200 pcs confirmed in stock, providing reliable supply availability for new designs and board revisions.
