CD74HC251M96 Equivalent & Substitute Parts

Part Overview

The CD74HC251M96 is a 1 x 8:1 multiplexer logic integrated circuit manufactured by Texas Instruments in a 16-SOIC surface mount package. This device is classified as Active product status with full availability (2208 pcs in stock). The CD74HC251M96 operates across a wide temperature range (-55°C to 125°C) and supports single supply voltage operation from 2V to 6V, making it suitable for general-purpose digital logic applications requiring multiplexing functionality.

Substitute parts are necessary when the primary part becomes unavailable, reaches end-of-life status, or when alternative packaging or sourcing from different manufacturers is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC251M96 is determined by strict equivalence across the following parameters:

• Circuit type and configuration (1 x 8:1 multiplexer)
• Output current specifications (5.2mA high and low)
• Single supply voltage operation (2V ~ 6V)
• Surface mount package compatibility (16-SOIC form factor)
• RoHS3 compliance and MSL rating
• Operating temperature range support

Substitute parts are grouped into the following categories:

Parametric Equivalents: Parts with identical electrical specifications and package form factor but potentially different manufacturers or packaging methods (Tape & Reel vs. Tube).

Direct Manufacturer Alternatives: Parts from alternative manufacturers (onsemi, Nexperia) that meet all electrical and mechanical specifications.

MFR Recommended Substitutes: Manufacturer-recommended alternatives that maintain full compatibility with identical parameter sets.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status)

CD74HC151M96 (Texas Instruments) and MC74HC251ADR2G (onsemi) are the preferred substitutes. Both maintain Active product status with full electrical and mechanical equivalence to the CD74HC251M96. CD74HC151M96 offers the highest inventory availability (3867 pcs) and identical Texas Instruments manufacturing lineage. MC74HC251ADR2G provides cross-manufacturer compatibility from onsemi with equivalent specifications and Tape & Reel packaging.

Secondary Substitutes (Limited Availability)

74HC251D,653 (Nexperia USA Inc.) is an Active product with full parameter equivalence but operates across a narrower temperature range (-40°C to 125°C versus -55°C to 125°C). This part is suitable for applications not requiring the extended low-temperature performance of the primary part. Packaging is provided as Cut Tape & Digi-Reel rather than standard Tape & Reel.

MC74HC251ADG (onsemi) maintains full electrical equivalence but is supplied in Tube packaging rather than Tape & Reel, requiring different handling and assembly processes.

End-of-Life Substitutes (Not Recommended for New Designs)

CD74HC151MT and CD74HC251MT carry Discontinued and Last Time Buy status respectively and should not be selected for new designs. NLV74HC251ADR2G is marked Obsolete and is unsuitable for production use.

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and equivalent RoHS and REACH certifications.

Frequently Asked Questions (FAQ)

Q: Can CD74HC151M96 be used as a direct replacement for CD74HC251M96?

A: Yes. CD74HC151M96 is a parametric equivalent with identical circuit configuration (1 x 8:1), output current (5.2mA), voltage supply range (2V ~ 6V), operating temperature range (-55°C ~ 125°C), and 16-SOIC package. Both are manufactured by Texas Instruments and carry Active product status.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging provides continuous component reels suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel packaging provides components on cut tape segments, typically used for lower-volume applications or manual assembly. Both formats contain identical components; the difference is in handling and assembly compatibility.

Q: Why does 74HC251D,653 have a narrower operating temperature range?

A: The 74HC251D,653 from Nexperia operates from -40°C to 125°C, compared to -55°C to 125°C for the CD74HC251M96. This difference reflects manufacturer process specifications. Selection depends on application temperature requirements. For applications operating above -40°C, this part is fully equivalent.

Q: Can I use MC74HC251ADG (Tube packaging) in automated assembly?

A: MC74HC251ADG is supplied in Tube packaging rather than Tape & Reel. Automated pick-and-place equipment typically requires Tape & Reel format. Tube packaging is suitable for manual assembly or requires reeling equipment for automation. Verify assembly process compatibility before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the compliance profile of the CD74HC251M96.

Q: Should I use parts with Discontinued or Obsolete status?

A: No. CD74HC151MT (Discontinued at DiGi Electronics), CD74HC251MT (Last Time Buy), and NLV74HC251ADR2G (Obsolete) should not be selected for new designs. These statuses indicate limited or no future availability. Use only Active status parts for production applications.
