• Manufacturer variation (Diodes Incorporated, Nexperia USA Inc.) permitted when all electrical and mechanical parameters align

Parameter Comparison

Engineering Selection Recommendations

74HCT125T14-13 (Diodes Incorporated): This part maintains identical electrical specifications and package configuration to the 74HCT126T14-13. Both devices share the same supply voltage range, operating temperature range, and 3-state output architecture. RoHS3 compliance and MSL rating are equivalent. This substitution is valid for applications requiring parametric equivalence.

74HCT126PW,118 (Nexperia USA Inc.): This part provides the same logic function, element count, and package footprint as the primary part. The output current specification is increased to 6mA per output (versus 4mA), which represents enhanced drive capability within the same voltage and temperature operating envelope. RoHS3 compliance and MSL rating match the primary part. This substitution is valid where increased output current capacity is acceptable or beneficial.

All substitute parts maintain active product status and full regulatory compliance (RoHS3, REACH unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can 74HCT125T14-13 replace 74HCT126T14-13 in all applications?

A: Yes, when parametric equivalence is the selection criterion. Both parts share identical logic type, element configuration, supply voltage range, operating temperature range, and package specifications. The parts are electrically and mechanically interchangeable.

Q: What is the difference between 74HCT126PW,118 and 74HCT126T14-13?

A: The primary difference is output current specification. The 74HCT126PW,118 provides 6mA output current versus 4mA for the 74HCT126T14-13. Both parts are manufactured to the same logic specifications and 14-TSSOP package standard. The higher output current of the Nexperia part may provide improved drive capability for certain load conditions.

Q: Are all substitute parts in the same package?

A: Yes. All listed parts use the 14-TSSOP surface mount package with 0.173" width (4.40mm). PCB footprint compatibility is maintained across all substitutes.

Q: Do substitute parts have the same compliance certifications?

A: Yes. All parts listed are RoHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.

Q: Can I use 74HCT126PW,118 where higher output current is not required?

A: Yes. The 74HCT126PW,118 is a valid substitute even when the increased output current specification is not utilized. The part meets all minimum electrical and mechanical requirements for the application.
