74HC158N,652 Equivalent & Substitute Parts

Part Overview

The 74HC158N,652 is a 4 x 2:1 multiplexer logic integrated circuit manufactured by NXP Semiconductors in a 16-DIP through-hole package. This component functions as a data selector, routing one of four input pairs to a single output based on control signals. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain functional equivalence in multiplexer configuration, electrical performance within specified tolerances, and physical compatibility with existing PCB designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC158N,652 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Multiplexer circuit configuration: 4 x 2:1
• Package format: 16-DIP (0.300", 7.62mm)
• Mounting technology: Through Hole
• Supply voltage range: 2V ~ 6V (minimum overlap required)
• Single supply source requirement

Acceptable Variation Parameters:

• Output current ratings may exceed the main part specification
• Operating temperature range may be narrower or wider
• RoHS compliance status may differ
• Product status (active vs. obsolete) does not disqualify substitution

The identified substitutes CD74HC157E and SN74HC158N meet these mandatory criteria and are therefore valid alternatives for the 74HC158N,652.

Parameter Comparison

Engineering Selection Recommendations

SN74HC158N (Texas Instruments) is the preferred substitute for new designs and production restocking. This part maintains ROHS3 compliance matching the original specification, carries active product status ensuring long-term availability, and provides higher output current capability (7.8mA vs. 5.2mA), which offers improved drive capability for downstream logic circuits. The operating temperature range of -40°C ~ 85°C covers standard industrial applications, though it is narrower than the original part.

CD74HC157E (Harris Corporation) is functionally compatible but presents compliance considerations. This substitute maintains identical electrical specifications and temperature range exceeding the original part (-55°C ~ 125°C), making it suitable for extended temperature applications. However, RoHS non-compliance status restricts its use in regulated markets and new product certifications. This part is appropriate only for legacy system maintenance where RoHS requirements do not apply.

Both substitutes are physically and electrically interchangeable within the specified parameter tolerances and require no PCB modifications for installation.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC157E and SN74HC158N be used interchangeably with the 74HC158N,652?

A: Both parts are functionally equivalent substitutes. Physical installation is identical due to matching 16-DIP package geometry. Electrical performance is compatible across the specified supply voltage range. Selection between them depends on compliance requirements and temperature operating range needs.

Q: What is the significance of the higher output current in the SN74HC158N?

A: The SN74HC158N provides 7.8mA output current compared to 5.2mA in the original part. This increased current capability allows driving more downstream logic gates or lower-impedance loads without exceeding output specifications. Circuits designed for the original 5.2mA specification will operate within safe margins with the higher-current substitute.

Q: Does RoHS compliance affect functional performance?

A: RoHS compliance is a manufacturing and environmental standard, not a functional specification. Both RoHS-compliant and non-compliant parts perform identically in circuit operation. Compliance status affects regulatory approval, supply chain acceptance, and market eligibility, not electrical behavior.

Q: Are there temperature range limitations when substituting?

A: The SN74HC158N operates within -40°C ~ 85°C, which is narrower than the original -40°C ~ 125°C range. Applications requiring operation above 85°C must use the original part or the CD74HC157E (-55°C ~ 125°C). For standard industrial temperature ranges (-40°C ~ 85°C), the SN74HC158N is fully suitable.

Q: Can these parts be soldered into existing PCBs designed for the 74HC158N,652?

A: Yes. All three parts use identical 16-DIP through-hole package geometry with 0.300" (7.62mm) row spacing. No PCB modifications, trace rerouting, or footprint changes are required. Direct component replacement is possible.
