Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC125APW-P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

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: 1.65V ~ 3.6V
Operating Temperature: -40°C ~ 125°C (TA)
Package / Case: 14-TSSOP (0.173", 4.40mm Width)

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the SN74LVC125APW-P based on electrical and mechanical parameter matching. Selection among these alternatives should be based on the following engineering criteria:

Compliance and Certification: Parts designated CLVC125AQPWRG4Q1, CLVC126AQPWRG4Q1, and SN74LVC125AQPWRQ1 carry AEC-Q100 automotive qualification. These variants are suitable for applications requiring automotive-grade component certification. The SN74LVC126APWT and 74LVC125APW/C5J do not specify AEC-Q100 qualification.

Packaging Format: The SN74LVC125APW-P is supplied in prototype packaging. Substitute parts are available in Tape & Reel (TR), Cut Tape & Digi-Reel (CT), and Bulk formats. Selection depends on production volume and assembly process requirements.

Manufacturer Source: Texas Instruments manufactures SN74LVC125APW-P, CLVC125AQPWRG4Q1, CLVC126AQPWRG4Q1, SN74LVC125AQPWRQ1, and SN74LVC126APWT. Nexperia USA Inc. manufactures 74LVC125APW/C5J. Both manufacturers produce ROHS3 compliant devices with identical electrical specifications.

Inventory Availability: The 74LVC125APW/C5J offers the highest inventory level (115,688 pcs), followed by SN74LVC125AQPWRQ1 (6,300 pcs). Selection based on supply chain requirements and lead time considerations is appropriate.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC125APW-P be directly replaced with CLVC125AQPWRG4Q1?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications: 4-element non-inverting buffer, 3-state output, 24mA output current, 1.65V to 3.6V supply voltage, -40°C to 125°C operating temperature, and 14-TSSOP package. The primary difference is packaging format and AEC-Q100 automotive qualification of the CLVC125AQPWRG4Q1.

Q: What is the difference between 74LVC125 and 74LVC126 base product numbers?

A: Both base product numbers (74LVC125 and 74LVC126) are listed as substitute options. The provided data indicates both maintain identical electrical parameters and package specifications. Selection between these variants should be confirmed against specific application requirements and design documentation.

Q: Is the 74LVC125APW/C5J from Nexperia USA Inc. compatible with the Texas Instruments SN74LVC125APW-P?

A: Yes. The 74LVC125APW/C5J meets all mandatory electrical and mechanical parameters: non-inverting buffer logic, 4 elements, 1 bit per element, 3-state output, 24mA output current, 1.65V to 3.6V supply voltage, -40°C to 125°C operating temperature, 14-TSSOP package, and ROHS3 compliance. Cross-manufacturer substitution is valid based on parameter equivalence.

Q: Do automotive-qualified variants (AEC-Q100) provide functional advantages over non-qualified variants?

A: AEC-Q100 qualification indicates the part has undergone automotive-specific reliability testing and quality assurance processes. Functionally, AEC-Q100 qualified parts (CLVC125AQPWRG4Q1, CLVC126AQPWRG4Q1, SN74LVC125AQPWRQ1) deliver identical electrical performance to non-qualified variants. Selection should be based on application requirements and industry standards compliance.

Q: What packaging formats are available for these substitute parts?

A: Substitute parts are available in three packaging formats: Tape & Reel (TR) for high-volume production, Cut Tape & Digi-Reel (CT) for moderate volumes, and Bulk for prototype or low-volume applications. The original SN74LVC125APW-P is supplied in prototype packaging. Format selection depends on manufacturing process and volume requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the SN74LVC125APW-P specification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all variants, indicating no moisture-related handling restrictions.
