74HC237PWJ Equivalent & Substitute Parts

Part Overview

The 74HC237PWJ is a decoder/demultiplexer logic integrated circuit manufactured by Nexperia USA Inc. in a 16-TSSOP surface mount package. This component functions as a 1 x 3:8 decoder/demultiplexer, converting a 3-bit binary input into one of eight active outputs. The device operates from a single supply voltage between 2V and 6V with an operating temperature range of -40°C to 125°C.

The 74HC237PWJ maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are necessary when the primary part number is unavailable, when alternative manufacturers are preferred, or when specific automotive qualifications (AEC-Q100) are required for particular applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC237PWJ is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Decoder/Demultiplexer circuit configuration: 1 x 3:8
• Output current specifications: 5.2mA high and low
• Supply voltage range: 2V to 6V
• Operating temperature range: -40°C to 125°C
• Package type: 16-TSSOP with 0.173" width and 4.40mm dimensions
• Surface mount mounting type
• RoHS3 compliance status

Substitute parts are grouped into two categories based on these parameters:

Standard Industrial Grade: Parts meeting all core electrical and mechanical parameters without automotive qualification.

Automotive Grade (AEC-Q100): Parts meeting all core parameters with additional automotive qualification certification, suitable for applications requiring automotive-level reliability.

All substitute parts listed maintain identical functional specifications, package dimensions, and compliance certifications as the primary 74HC237PWJ device.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications:

The 74HC138PW,118 (Nexperia) and 74HC138T16-13 (Diodes Incorporated) are direct industrial-grade substitutes with identical electrical and mechanical specifications. The 74HC138T16-13 offers the highest inventory availability at 20,400 pieces. The 74HC238PW,118 (Nexperia) is functionally equivalent and maintains the same parametric specifications with higher inventory (7,077 pieces).

For Automotive Applications Requiring AEC-Q100 Qualification:

The 74HC138PW-Q100,118 (Nexperia), 74HC238PW-Q100J (Nexperia), SN74HC138QPWRG4Q1 (Texas Instruments), and SN74HC138QPWRQ1 (Texas Instruments) are qualified automotive-grade alternatives. All maintain identical electrical performance and package specifications while meeting automotive reliability standards.

The SN74HC138QPWRQ1 provides the highest inventory availability among automotive-qualified options at 8,100 pieces. The SN74HC138QPWRG4Q1 offers 2,441 pieces with equivalent automotive qualification.

Moisture Sensitivity Consideration:

The SN74HC138QPWRQ1 specifies MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for other parts. This difference affects storage and handling requirements but does not impact electrical performance or functional compatibility.

All listed substitutes maintain RoHS3 compliance and REACH unaffected status consistent with the primary 74HC237PWJ device.

Frequently Asked Questions (FAQ)

Q: Can the 74HC138 series parts substitute for the 74HC237PWJ?

A: Yes. The 74HC138 and 74HC238 series parts are parametrically equivalent to the 74HC237PWJ across all critical specifications: 1 x 3:8 decoder/demultiplexer configuration, 5.2mA output current, 2V to 6V supply voltage, -40°C to 125°C operating temperature, and 16-TSSOP package. All are RoHS3 compliant with identical moisture sensitivity ratings.

Q: What is the difference between industrial and automotive-grade parts?

A: Automotive-grade parts carry AEC-Q100 qualification, indicating compliance with automotive reliability and quality standards. Electrical and mechanical specifications remain identical to industrial-grade equivalents. Automotive-grade parts are required for applications subject to automotive industry standards or customer specifications.

Q: Are there packaging differences between substitute parts?

A: All listed substitutes use the 16-TSSOP package with identical dimensions (0.173" width, 4.40mm). Packaging format differs between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® options, which affects handling and storage but not component functionality or compatibility.

Q: Does the MSL 3 rating on the SN74HC138QPWRQ1 affect compatibility?

A: No. MSL 3 (168 Hours) affects moisture exposure handling and storage requirements but does not impact electrical performance or functional compatibility. The component operates identically to MSL 1 parts once properly handled and soldered.

Q: Which substitute offers the best inventory availability?

A: The 74HC138T16-13 (Diodes Incorporated) provides the highest inventory at 20,400 pieces for industrial applications. For automotive-qualified parts, the SN74HC138QPWRQ1 (Texas Instruments) offers 8,100 pieces.

Q: Are all substitutes from the same manufacturer?

A: No. Substitutes are available from Nexperia USA Inc., Diodes Incorporated, and Texas Instruments. All maintain identical parametric specifications and compliance certifications despite different manufacturers.
