Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74HCT151D,652 are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Equivalence Criteria:

• Circuit configuration: 1 x 8:1 multiplexer topology
• Output current specifications: 4mA high, 4mA low
• Supply voltage range: 4.5V ~ 5.5V
• Logic series: 74HCT family

Mechanical Compatibility Criteria:

• Package type: 16-SOIC surface mount
• Physical dimensions: 0.154" width, 3.90mm width
• Pin count and arrangement: 16-pin configuration

Environmental Criteria:

• Operating temperature range compatibility
• Moisture sensitivity level classification

Parts meeting all three criteria categories are classified as direct parametric equivalents or upgrades. Variations in product status, RoHS compliance, or manufacturer do not affect electrical or mechanical substitutability when all core parameters align.

Engineering Selection Recommendations

74HCT251D,652 (Parametric Equivalent) This part maintains identical electrical and mechanical specifications to the 74HCT151D,652. Both components are ROHS3 compliant and share equivalent product status classification. Selection of this substitute is appropriate when maintaining consistency with existing RoHS compliance documentation and Nexperia manufacturer sourcing.

CD74HCT151M and CD74HCT151M96 (Upgrade Options) These Harris Corporation manufactured parts provide expanded operating temperature range (-55°C ~ 125°C versus -40°C ~ 125°C), offering enhanced performance in extended temperature environments. Both parts maintain identical electrical output specifications and 16-SOIC package compatibility. These components are RoHS non-compliant; selection requires verification of project compliance requirements. The CD74HCT151M is supplied in tube packaging, while CD74HCT151M96 is supplied in bulk packaging.

Selection between these upgrades depends on temperature operating requirements and RoHS compliance mandates specific to the application and regulatory environment.

Frequently Asked Questions (FAQ)

Q: Can 74HCT251D,652 be used as a direct replacement for 74HCT151D,652? A: Yes. Both parts share identical electrical specifications (4mA output current, 4.5V ~ 5.5V supply voltage), circuit configuration (1 x 8:1 multiplexer), and 16-SOIC package dimensions. The parts are functionally interchangeable.

Q: What is the primary difference between the Nexperia and Harris Corporation options? A: The Harris Corporation parts (CD74HCT151M and CD74HCT151M96) extend the operating temperature range to -55°C ~ 125°C, compared to -40°C ~ 125°C for Nexperia parts. Electrical output specifications remain identical. RoHS compliance status differs: Nexperia parts are ROHS3 compliant; Harris parts are RoHS non-compliant.

Q: Are packaging differences between tube and bulk significant for substitution? A: Packaging format (tube versus bulk) affects handling, storage, and procurement logistics but does not impact electrical or mechanical compatibility. Both CD74HCT151M (tube) and CD74HCT151M96 (bulk) are electrically identical and mechanically compatible with the original 74HCT151D,652.

Q: Should I select a substitute based on RoHS compliance? A: RoHS compliance selection depends on project requirements and regulatory environment. If ROHS3 compliance is mandatory, select 74HCT251D,652. If extended temperature performance is prioritized and RoHS non-compliance is acceptable, CD74HCT151M or CD74HCT151M96 are suitable.

Q: Are all substitute parts available in equivalent quantities? A: Inventory levels vary by part number and supplier. Verify current stock availability with your component supplier before finalizing procurement decisions.
