Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM74HC4050M is determined by the following critical parameters:

• Logic Type: Buffer, Non-Inverting (6 elements, 1 bit per element)
• Output Type: Push-Pull
• Output Current: 5.2mA (high and low)
• Supply Voltage Range: 2V ~ 6V
• Package / Case: 16-SOIC with 0.154" (3.90mm) width
• Mounting Type: Surface Mount

All substitute parts must maintain identical logic configuration, output characteristics, and supply voltage specifications. Package dimensions and mounting type are critical for PCB compatibility. Parts are categorized as direct substitutes (identical specifications), upgrades (enhanced operating temperature or product status), or similar alternatives (minor package variations).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute - CD74HC4050M (Texas Instruments)

The CD74HC4050M from Texas Instruments provides direct functional equivalence to the MM74HC4050M. Both parts share identical logic configuration, output characteristics, supply voltage range, and 16-SOIC package dimensions. The CD74HC4050M offers an extended operating temperature range (-55°C to 125°C versus -40°C to 85°C) and holds Last Time Buy status, providing a defined procurement window for legacy design support.

Preferred Upgrade - 74HC4050D,653 (Nexperia USA Inc.)

The 74HC4050D,653 is classified as an active product with full ROHS3 compliance, offering superior long-term availability compared to the obsolete MM74HC4050M. This part maintains all critical electrical parameters and package specifications while providing an extended operating temperature range (-40°C to 125°C). The active product status ensures continued manufacturing and supply chain stability.

Alternative Upgrade - CD74HC4050M96 (Texas Instruments)

The CD74HC4050M96 is an active product offering identical electrical specifications and 16-SOIC package dimensions to the MM74HC4050M. This part provides extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. Packaging is supplied as Cut Tape (CT) & Digi-Reel®, suitable for automated assembly processes.

Last Time Buy Option - CD74HC4050MT (Texas Instruments)

The CD74HC4050MT maintains full electrical and package compatibility with the MM74HC4050M while offering extended operating temperature range (-55°C to 125°C) and ROHS3 compliance. This part is available in Tape & Reel (TR) packaging and holds Last Time Buy status.

Package Variant - CD74HC4050NSR (Texas Instruments)

The CD74HC4050NSR provides functional equivalence with identical logic configuration and electrical specifications. This part features a slightly wider 16-SO package (0.209" versus 0.154" width) and is an active product with ROHS3 compliance. PCB layout verification is required to confirm package footprint compatibility before selection.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4050M directly replace the MM74HC4050M on existing PCBs?

A: Yes. The CD74HC4050M shares identical electrical specifications, output characteristics, and 16-SOIC package dimensions (0.154", 3.90mm width) with the MM74HC4050M. No circuit modifications are required for direct substitution.

Q: What is the primary reason for seeking substitutes for the MM74HC4050M?

A: The MM74HC4050M is classified as obsolete. Substitute parts ensure design continuity and production support through active or Last Time Buy alternatives from established manufacturers.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts from Texas Instruments and Nexperia are ROHS3 compliant. The original MM74HC4050M from onsemi does not specify RoHS status.

Q: Does the extended operating temperature range of substitute parts affect circuit design?

A: No. The extended temperature ranges (-55°C to 125°C) of substitute parts are supersets of the original MM74HC4050M specification (-40°C to 85°C). All parts maintain identical electrical performance within the original operating range.

Q: Is the CD74HC4050NSR compatible with the MM74HC4050M footprint?

A: The CD74HC4050NSR uses a 16-SO package with 0.209" width, compared to the MM74HC4050M's 0.154" width. PCB layout verification is required to confirm footprint compatibility before selection, as the wider package may not fit existing board designs.

Q: Which substitute part offers the best long-term availability?

A: The 74HC4050D,653 from Nexperia is classified as an active product, providing the longest procurement window and manufacturing continuity. The CD74HC4050M96 from Texas Instruments is also active and offers equivalent long-term availability.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tube (CD74HC4050M), Tape & Reel (74HC4050D,653 and CD74HC4050MT), and Cut Tape & Digi-Reel® (CD74HC4050M96 and CD74HC4050NSR). Selection depends on production volume and assembly process requirements.
