Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74LVC126AD-Q100J are identified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Equivalence Criteria:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 4
• Number of Bits per Element: 1
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 1.2V ~ 3.6V
• Operating Temperature: -40°C ~ 125°C (TA)

Mechanical Compatibility Criteria:

• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 14-SO

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts match these parameters exactly. Variations in base product number (74LVC125 vs. 74LVC126) and packaging code suffix (,118 vs. -Q100J) do not affect electrical or mechanical compatibility when all specified parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full compliance with ROHS3 and REACH requirements. Selection between substitute options depends on application-specific requirements:

For Automotive Applications: Parts carrying AEC-Q100 qualification (74LVC126AD-Q100J and 74LVC125AD-Q100J) are suitable for automotive-grade implementations. These parts meet automotive reliability and qualification standards.

For General Industrial Applications: All four parts are suitable, as they share identical electrical specifications and package compatibility. Parts without explicit automotive qualification (74LVC125AD,118 and 74LVC126AD,118) are appropriate for non-automotive applications.

Inventory Availability: Selection may be influenced by stock levels. The 74LVC125AD,118 variant maintains the highest inventory (98,042 pcs), while 74LVC125AD-Q100J and 74LVC126AD,118 maintain moderate stock levels (3,222 pcs and 5,426 pcs respectively).

Frequently Asked Questions (FAQ)

Q: Can 74LVC125AD substitute for 74LVC126AD? A: Yes. Both parts are non-inverting buffers with 4 elements, 1 bit per element, 3-state output, identical electrical ratings (24mA output current, 1.2V–3.6V supply), and the same 14-SOIC package. The functional difference between 74LVC125 and 74LVC126 series does not affect substitution eligibility when all specified parameters match.

Q: What is the difference between packaging codes ,118 and -Q100J? A: The packaging code suffix indicates the tape and reel configuration and qualification level. The -Q100J suffix denotes AEC-Q100 automotive qualification, while ,118 indicates standard commercial packaging. Both are 14-SO surface mount packages with identical physical dimensions (0.154", 3.90mm width) and are mechanically interchangeable.

Q: Are these parts suitable for automotive applications? A: Parts designated with -Q100J (74LVC126AD-Q100J and 74LVC125AD-Q100J) carry AEC-Q100 automotive qualification and are suitable for automotive applications. Parts with ,118 suffix do not carry explicit automotive qualification and should be evaluated against specific automotive requirements.

Q: Do all substitute parts have the same moisture sensitivity? A: Yes. All parts listed carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Are these parts RoHS compliant? A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
