CD74HC123M96 Equivalent & Substitute Parts

Part Overview

The CD74HC123M96 is a monostable multivibrator logic integrated circuit manufactured by Texas Instruments. This device features two independent circuits with a 25 ns propagation delay, operating across a 2 V to 6 V supply voltage range. The part is housed in a 16-SOIC surface mount package and maintains active product status with full RoHS3 compliance. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative packaging or qualification requirements are necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74HC123M96 are qualified based on the following criteria:

Core Functional Equivalence: All substitute parts maintain the same base product number (74HC123), logic type (monostable multivibrator), and independent circuit count (2). This ensures functional compatibility at the circuit level.

Electrical Parameter Compatibility: Substitute parts operate within the same supply voltage range (2 V ~ 6 V) and deliver identical output current specifications (5.2 mA, 5.2 mA). While propagation delay may vary (25 ns to 65 ns), this remains within acceptable tolerance for monostable multivibrator applications.

Package and Mounting Compatibility: All substitute parts use the 16-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width), ensuring direct PCB footprint compatibility.

Compliance and Regulatory Alignment: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical ECCN and HTSUS classifications, supporting regulatory and supply chain requirements.

Key Differentiators: Propagation delay (25 ns vs. 65 ns), operating temperature range (-55°C ~ 125°C vs. -40°C ~ 125°C), packaging format (Cut Tape vs. Tape & Reel), and automotive qualification (AEC-Q100) distinguish substitute options for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: The CD74HC123M96 (Texas Instruments) offers the fastest propagation delay (25 ns) and the widest operating temperature range (-55°C ~ 125°C). This part is suitable for applications requiring maximum speed performance and extended low-temperature operation.

For General-Purpose Substitution: The 74HC123D,653 (Nexperia USA Inc.) provides functional equivalence with identical electrical and package specifications. The 65 ns propagation delay remains acceptable for most monostable multivibrator applications. This part is available in Cut Tape and Digi-Reel packaging formats.

For Automotive and High-Reliability Applications: The 74HC123D-Q100,118 (Nexperia USA Inc.) carries AEC-Q100 automotive qualification and is supplied in Tape & Reel format. This part is specified for automotive-grade designs and applications requiring formal qualification documentation. The operating temperature range is -40°C ~ 125°C, suitable for automotive environmental conditions.

Compliance Considerations: All three parts maintain ROHS3 compliance, MSL Level 1 rating, and identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001), supporting unrestricted procurement and deployment across regulated supply chains.

Frequently Asked Questions (FAQ)

Q: Can the 74HC123D,653 directly replace the CD74HC123M96 on an existing PCB?

A: Yes. Both parts use the 16-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width) and pinout. PCB footprints are directly compatible. The 65 ns propagation delay of the 74HC123D,653 is acceptable for applications where the CD74HC123M96's 25 ns delay is not a critical timing requirement.

Q: What is the difference between the 74HC123D,653 and 74HC123D-Q100,118?

A: Both parts share identical electrical specifications and package dimensions. The primary differences are: (1) the 74HC123D-Q100,118 carries AEC-Q100 automotive qualification; (2) the 74HC123D-Q100,118 is supplied in Tape & Reel format, while the 74HC123D,653 is available in Cut Tape and Digi-Reel formats. Select the AEC-Q100 variant for automotive applications requiring formal qualification.

Q: Are there temperature range limitations when substituting the CD74HC123M96?

A: The CD74HC123M96 operates from -55°C ~ 125°C. Both Nexperia substitutes operate from -40°C ~ 125°C. If your application requires operation below -40°C, the CD74HC123M96 is the only option among these three parts.

Q: Do all three parts have the same RoHS and moisture sensitivity ratings?

A: Yes. All three parts are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. They are equivalent in regulatory compliance and handling requirements.

Q: What packaging options are available for each part?

A: The CD74HC123M96 is supplied in Cut Tape (CT) and Digi-Reel® formats. The 74HC123D,653 is supplied in Cut Tape (CT) and Digi-Reel® formats. The 74HC123D-Q100,118 is supplied in Tape & Reel (TR) format. Select based on your procurement and assembly process requirements.
