Substitute Part Grouping Explanation

Substitution eligibility for the 74HCT107N,652 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Base product number must be 74HCT107 (ensures identical logic function and pin configuration)
• Type must be JK Type flip-flop with 2 elements, 1 bit per element
• Output type must be complementary
• Trigger type must be negative edge
• Package must be 14-DIP (0.300", 7.62mm) for mechanical and electrical compatibility

Electrical Compatibility Criteria:

• Voltage supply range: 4.5V ~ 5.5V
• Mounting type: Through Hole
• Pin count and pinout must be identical

The CD74HCT107E manufactured by Harris Corporation meets all functional and electrical equivalence criteria, confirming its status as a direct substitute for the 74HCT107N,652.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CD74HCT107E

The CD74HCT107E is a direct functional equivalent of the 74HCT107N,652. Both components share identical logic function, pin configuration, package form factor, and core electrical specifications. The CD74HCT107E is suitable for replacement in applications where the 74HCT107N,652 is no longer available.

Compliance Considerations:

The 74HCT107N,652 carries ROHS3 compliance certification, while the CD74HCT107E is RoHS non-compliant. In applications subject to RoHS regulatory requirements, component selection must account for this compliance difference. Both parts are classified as obsolete products, reflecting their legacy status in the semiconductor market.

Performance Variance:

The CD74HCT107E exhibits slightly reduced clock frequency (56 MHz versus 66 MHz) and marginally increased propagation delay (43ns versus 36ns). These differences are within typical design margins for most digital logic applications. The CD74HCT107E provides an extended operating temperature range (-55°C to 125°C versus -40°C to 125°C), offering broader environmental tolerance.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT107E be used as a direct replacement for the 74HCT107N,652?

A: Yes. Both components are 74HCT107 base products with identical logic function, pin configuration, and 14-DIP package. Electrical specifications for supply voltage, output current, and quiescent current are identical. The CD74HCT107E is a direct functional substitute.

Q: What are the differences between these two parts?

A: The primary differences are clock frequency (56 MHz versus 66 MHz), propagation delay (43ns versus 36ns at 4.5V, 50pF), input capacitance (10 pF versus 3.5 pF), and operating temperature range (-55°C to 125°C versus -40°C to 125°C). The 74HCT107N,652 is RoHS3 compliant; the CD74HCT107E is not.

Q: Are there any package compatibility issues?

A: No. Both components use identical 14-DIP (0.300", 7.62mm) through-hole packaging. Pin count, pinout, and mechanical dimensions are identical, ensuring direct board-level compatibility.

Q: Which part should I select for new designs?

A: Both parts are classified as obsolete. For new designs, consult current logic device datasheets and availability. If legacy system repair or maintenance requires one of these specific parts, the CD74HCT107E provides functional equivalence with extended temperature range capability.

Q: Does the reduced clock frequency of the CD74HCT107E affect compatibility?

A: The CD74HCT107E's 56 MHz clock frequency is lower than the 74HCT107N,652's 66 MHz specification. In applications operating below 56 MHz, this difference is not a limiting factor. Applications requiring operation above 56 MHz should retain the original 74HCT107N,652 specification.

Q: What is the significance of RoHS compliance differences?

A: The 74HCT107N,652 is RoHS3 compliant; the CD74HCT107E is not. In applications or markets subject to RoHS regulatory requirements, component selection must account for this compliance status. Verify regulatory requirements for your specific application before substitution.
