Substitute Part Grouping Explanation

Substitution of the 74HC32D/AUJ is determined by strict equivalence across the following critical parameters:

• Logic function: 4-channel OR gate with 2 inputs per channel
• Electrical specifications: Supply voltage range 2V ~ 6V, quiescent current 2 µA maximum, output current 5.2mA for both high and low states
• Input logic thresholds: Low 0.5V ~ 1.8V, High 1.5V ~ 4.2V
• Timing performance: Maximum propagation delay of 15ns at 6V with 50pF load
• Temperature range: -40°C to 125°C operation
• Package format: 14-SOIC surface mount configuration with 0.154" width (3.90mm)
• Compliance: RoHS3 certification and MSL Level 1 rating

The 74HC32D,653 from Nexperia USA Inc. meets all specified parameters identically and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 74HC32D/AUJ and 74HC32D,653 maintain active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is based on availability and packaging format preference. The 74HC32D/AUJ is supplied in standard packaging, while the 74HC32D,653 is available in Cut Tape (CT) and Digi-Reel® formats. Inventory levels should be evaluated based on project requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 74HC32D,653 directly replace the 74HC32D/AUJ in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including supply voltage, logic thresholds, propagation delay, operating temperature range, and 14-SOIC package dimensions.

Q: Are there differences in packaging that affect PCB assembly?

A: Both parts use identical 14-SOIC (0.154", 3.90mm Width) surface mount packages. The 74HC32D,653 is available in Cut Tape and Digi-Reel® formats, which are standard tape-and-reel configurations for automated assembly. Package footprint and pin configuration are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 74HC32D/AUJ and 74HC32D,653 are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching logic function (4-channel 2-input OR gate), supply voltage range (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), input logic thresholds, propagation delay (15ns @ 6V, 50pF), operating temperature (-40°C ~ 125°C), and package format (14-SOIC).

Q: Are there any restrictions on using these parts interchangeably?

A: No restrictions exist based on the provided electrical and mechanical parameters. Both parts are functionally and physically equivalent for direct substitution in 14-SO surface mount applications.
