Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC107D,652 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Flip-flop type: JK Type with 2 elements, 1 bit per element
• Output configuration: Complementary outputs
• Trigger mechanism: Negative edge-triggered
• Function: Reset capability
• Package: 14-SOIC (0.154", 3.90mm Width) surface mount
• Supply voltage range: 2V ~ 6V
• Output current capability: 5.2 mA (high and low)
• Quiescent current: 4 µA
• RoHS3 compliance and MSL Level 1

Acceptable Parameter Variations:

• Clock frequency: Substitute parts may operate at 60 MHz (lower than 85 MHz original)
• Propagation delay: Substitute parts may have up to 29 ns delay (within acceptable logic timing margins)
• Input capacitance: Substitute parts may have up to 10 pF (higher than 4.6 pF original)
• Operating temperature range: Substitute parts may extend to -55°C minimum (broader range acceptable)
• Packaging format: Tube or Tape & Reel (TR) both acceptable for surface mount 14-SOIC

All identified substitutes belong to the 74HC logic family and maintain functional equivalence within the specified parameter tolerances.

Engineering Selection Recommendations

Primary Recommendation: CD74HC107M96

The CD74HC107M96 manufactured by Texas Instruments is the optimal substitute for the 74HC107D,652. This part maintains identical base product number (74HC107), ensuring pin-for-pin compatibility and functional equivalence. The CD74HC107M96 carries an Active product status, providing long-term availability and supply chain stability. All electrical parameters remain within acceptable tolerances: propagation delay of 29 ns versus the original 27 ns represents a 7.4% variance, well within typical logic circuit timing margins. The extended operating temperature range (-55°C to 125°C) provides broader environmental coverage than the original specification. ROHS3 compliance and MSL Level 1 certification match the original part exactly.

Secondary Recommendation: CD74HC107M

The CD74HC107M from Texas Instruments serves as an alternative substitute with identical electrical specifications to the CD74HC107M96. This part is classified as Last Time Buy, indicating limited future availability. The Tube packaging format matches the original 74HC107D,652 configuration. Selection of this part should account for its discontinuation trajectory.

Alternative Consideration: CD74HC73M

The CD74HC73M represents a functional alternative based on equivalent JK flip-flop architecture. However, this part uses the 74HC73 base product number rather than 74HC107, indicating a different device variant. While electrical parameters remain compatible, the different base product number may require circuit board layout verification to confirm pinout alignment. This part is classified as Discontinued at DiGi Electronics and should be considered only when primary recommendations are unavailable.

Packaging Format Selection:

For new production designs, CD74HC107M96 in Tape & Reel format is preferred for automated assembly processes. For manual assembly or low-volume applications, CD74HC107M in Tube format provides equivalent functionality.

Frequently Asked Questions (FAQ)

Q: Can CD74HC107M96 be used as a direct replacement for 74HC107D,652 without circuit modifications?

A: Yes. Both parts share the 74HC107 base product number, confirming identical pinout and functional behavior. The 14-SOIC package dimensions are identical (0.154", 3.90mm width). Electrical parameters remain within acceptable tolerances for logic circuit operation.

Q: What is the significance of the different base product numbers (74HC107 vs. 74HC73)?

A: The base product number identifies the specific device variant within the 74HC logic family. 74HC107 and 74HC73 are distinct devices with different internal architectures. While both are dual JK-type flip-flops with complementary outputs, the 74HC73 should be used only when 74HC107 substitutes are unavailable, and pinout compatibility must be verified against the original circuit design.

Q: Why does the CD74HC107M96 have a lower clock frequency (60 MHz) than the original 74HC107D,652 (85 MHz)?

A: The 60 MHz specification for Texas Instruments parts reflects conservative guaranteed performance across the full operating temperature and voltage range. The original 85 MHz specification may represent typical performance under nominal conditions. For most logic applications, 60 MHz provides sufficient timing margin. Applications requiring the full 85 MHz specification should be evaluated against actual circuit timing requirements.

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

A: Tube packaging contains loose components suitable for manual assembly or low-volume production. Tape & Reel packaging presents components in continuous tape format optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging selection depends on assembly methodology. The 14-SOIC package dimensions remain identical regardless of format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant certification, matching the original 74HC107D,652. All parts also maintain MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control requirements during storage or handling.

Q: What is the impact of the extended operating temperature range (-55°C to 125°C) in substitute parts?

A: The extended lower temperature limit (-55°C versus -40°C) provides broader environmental coverage without affecting performance within the original specification range. This represents an enhancement rather than a limitation. Applications operating within the original -40°C to 125°C range experience no functional change.

Q: Can CD74HC73M be used interchangeably with CD74HC107M?

A: No. While both are dual JK-type flip-flops with similar electrical characteristics, the different base product numbers (74HC73 vs. 74HC107) indicate distinct device variants. Pinout compatibility must be verified against the original circuit schematic before substitution. Use CD74HC73M only when 74HC107-based substitutes are unavailable.
