Substitute Part Grouping Explanation

Substitution of the 74HC107N,652 is determined by strict equivalence across the following critical parameters:

Functional Equivalence Requirements:

• Base product number: 74HC107
• Logic type: JK-type flip-flop
• Number of elements: 2
• Number of bits per element: 1
• Output type: Complementary
• Trigger type: Negative edge
• Package type: 14-DIP (0.300", 7.62mm)
• Mounting type: Through hole

Electrical Compatibility Parameters:

• Supply voltage range: 2V ~ 6V
• Output current capability: 5.2mA (high and low)
• Quiescent current: 4 µA

The CD74HC107E manufactured by Harris Corporation meets all functional and electrical equivalence criteria. Both parts share the identical base product number (74HC107), package configuration, and core electrical specifications, establishing direct substitutability within the 74HC logic family.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The CD74HC107E serves as a direct functional substitute for the 74HC107N,652 based on identical logic architecture, package configuration, and core electrical specifications. Both components are classified as obsolete products within the 74HC logic family.

Compliance Considerations:

The 74HC107N,652 maintains ROHS3 compliance, while the CD74HC107E is RoHS non-compliant. Selection between these parts depends on regulatory requirements applicable to the end application. For systems requiring RoHS compliance, the 74HC107N,652 is the appropriate choice. For legacy systems or applications without RoHS mandates, the CD74HC107E remains functionally equivalent.

Performance Characteristics:

The 74HC107N,652 exhibits superior performance specifications with a maximum clock frequency of 85 MHz compared to 60 MHz for the CD74HC107E, and faster propagation delay of 27ns versus 29ns. The 74HC107N,652 also features lower input capacitance at 4.6 pF versus 10 pF. These differences are marginal within typical logic circuit applications.

The CD74HC107E provides an extended operating temperature range of -55°C to 125°C compared to -40°C to 125°C for the 74HC107N,652, offering broader environmental tolerance.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC107E directly replace the 74HC107N,652 in existing designs?

A: Yes. Both parts share identical functional specifications, logic type, package configuration, and electrical characteristics. Pin-for-pin substitution is possible without circuit modification.

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

A: The primary differences are: (1) RoHS compliance status—74HC107N,652 is ROHS3 compliant while CD74HC107E is non-compliant; (2) clock frequency—74HC107N,652 supports 85 MHz versus 60 MHz; (3) propagation delay—74HC107N,652 has 27ns versus 29ns; (4) input capacitance—74HC107N,652 has 4.6 pF versus 10 pF; (5) operating temperature range—CD74HC107E extends to -55°C versus -40°C minimum.

Q: Are both parts available in the same package?

A: Yes. Both the 74HC107N,652 and CD74HC107E are packaged in 14-DIP (0.300", 7.62mm) through-hole configuration with identical pin assignments.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and environmental requirements. For RoHS-compliant applications, the 74HC107N,652 is required. For applications requiring extended low-temperature operation below -40°C, the CD74HC107E is suitable. Both parts are obsolete; availability should be confirmed with component suppliers before design commitment.

Q: Do these parts have identical electrical performance?

A: Core electrical specifications are equivalent. The 74HC107N,652 offers marginally faster performance (27ns propagation delay, 85 MHz clock frequency, 4.6 pF input capacitance) compared to the CD74HC107E (29ns, 60 MHz, 10 pF). These differences are negligible in most logic applications.

Q: What is the significance of the obsolete product status?

A: Both parts are classified as obsolete, indicating they are no longer in active production. Component availability is limited to existing inventory. Long-term sourcing should consider alternative modern logic families if production volumes or extended supply requirements are anticipated.
