CD74HC107M Equivalent & Substitute Parts

Part Overview

The CD74HC107M is a dual JK-type flip-flop logic integrated circuit manufactured by Texas Instruments in 14-SOIC surface mount packaging. This device functions as a reset-capable flip-flop with complementary outputs, operating across a 2V to 6V supply voltage range. The part is currently in Last Time Buy status, indicating production discontinuation. Alternative equivalent and substitute parts are necessary for ongoing design support, inventory replenishment, and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC107M is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Logic family and base product number (74HC series)
• Flip-flop type (JK Type, Dual 1-Bit configuration)
• Function (Reset capability)
• Output type (Complementary)
• Trigger mechanism (Negative Edge)
• Package type (14-SOIC surface mount)
• Supply voltage range (2V – 6V minimum compatibility)
• Operating temperature range (must support –55°C to +125°C or equivalent industrial range)
• RoHS and REACH compliance status

Substitute Categories:

1. Manufacturer Recommended Direct Substitutes – Parts with identical or superior electrical performance, same packaging, and active product status
2. Parametric Equivalents – Parts meeting all functional requirements with minor variations in performance metrics or discontinued status

All substitute parts listed maintain the 14-SOIC package footprint, JK-type flip-flop architecture, and negative-edge trigger configuration required for direct circuit board replacement.

Parameter Comparison

Engineering Selection Recommendations

CD74HC107M96 (Texas Instruments) Primary substitute with identical electrical specifications and active product status. Differs only in packaging format (Tape & Reel vs. Tube). Recommended for new production orders and long-term availability assurance.

74HC107D,653 (Nexperia USA Inc.) Active substitute with superior propagation delay performance (27 ns vs. 29 ns) and higher clock frequency rating (85 MHz vs. 60 MHz). Operating temperature range limited to –40°C to +125°C; suitable for applications not requiring full –55°C lower temperature specification. Lower input capacitance (4.6 pF) may provide marginal timing advantages in specific circuit topologies.

MC74HC73ADR2G (onsemi) Active substitute with highest inventory availability (10,200 pcs). Meets all functional requirements with lower propagation delay (21 ns) and lower clock frequency rating (35 MHz). Tape & Reel packaging suitable for automated assembly. Recommended for high-volume production requiring extended lead-time protection.

MC74HC73ADG (onsemi) Active substitute functionally equivalent to MC74HC73ADR2G with identical electrical performance. Tube packaging format. Lower clock frequency rating (35 MHz) and propagation delay (21 ns) indicate different silicon process generation. Suitable for applications with relaxed timing requirements.

CD74HC73M (Texas Instruments) Parametric equivalent with discontinued status at DiGi Electronics. Maintains Texas Instruments manufacturing lineage with 60 MHz clock frequency and 28 ns propagation delay. Limited inventory (2,100 pcs). Not recommended for new designs due to discontinuation status; suitable only for legacy system maintenance where existing supply chain relationships exist.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and EAR99 export classification consistent with the original CD74HC107M specification.

Frequently Asked Questions (FAQ)

Q: Can CD74HC107M be replaced with MC74HC73ADR2G in existing designs? A: Yes. Both devices are dual JK-type flip-flops with negative-edge triggering, complementary outputs, and 14-SOIC packaging. Electrical parameters (supply voltage, output current, quiescent current) are identical. The MC74HC73ADR2G exhibits faster propagation delay (21 ns vs. 29 ns), which is compatible with CD74HC107M timing requirements. Pin-for-pin compatibility is maintained.

Q: What is the difference between CD74HC107M and CD74HC107M96? A: These parts are electrically identical. The primary difference is packaging format: CD74HC107M is supplied in Tube packaging, while CD74HC107M96 is supplied in Tape & Reel format. CD74HC107M96 is recommended for new production due to active product status versus Last Time Buy status of the original part.

Q: Why do some substitutes have lower clock frequency ratings? A: MC74HC73ADG and MC74HC73ADR2G are rated at 35 MHz versus 60 MHz for the CD74HC107M. This reflects different silicon process generations and manufacturing specifications. Lower frequency ratings do not prevent operation at higher frequencies in practical applications; they represent conservative manufacturer specifications. These parts are suitable for applications operating at or below their rated frequency.

Q: Is the 74HC107D,653 from Nexperia suitable for –55°C applications? A: The 74HC107D,653 is rated for –40°C to +125°C operating temperature. Applications requiring full –55°C to +125°C range should use CD74HC107M96, MC74HC73ADR2G, MC74HC73ADG, or CD74HC73M, which all support the extended lower temperature specification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, consistent with the original CD74HC107M specification.

Q: What is the recommended substitute for high-volume production? A: MC74HC73ADR2G is recommended for high-volume production. It offers the highest inventory availability (10,200 pcs), active product status, Tape & Reel packaging suitable for automated assembly, and superior propagation delay performance (21 ns). This combination provides lead-time protection and manufacturing efficiency.

Q: Can CD74HC73M be used as a substitute despite discontinued status? A: CD74HC73M is functionally equivalent with 60 MHz clock frequency and 28 ns propagation delay. However, discontinued status at DiGi Electronics limits availability (2,100 pcs remaining). Use only for legacy system maintenance or repair applications where existing supply relationships are established. New designs should use active alternatives.
