ZTX968STOA Equivalent & Substitute Parts

Part Overview

The ZTX968STOA is a Bipolar (BJT) Transistor, PNP type, manufactured by Diodes Incorporated. This component is designed for applications requiring a 12 V collector-emitter breakdown voltage with a maximum collector current of 4.5 A and maximum power dissipation of 1.58 W. The device features an 80 MHz transition frequency and operates across a temperature range of -55°C to 200°C.

The ZTX968STOA is classified as an obsolete product. Identification of equivalent substitute parts is necessary to support ongoing maintenance, repair, and redesign activities where this component is specified in existing designs or where inventory depletion requires alternative sourcing.

Substitute Part Grouping Explanation

Substitution of the ZTX968STOA is determined by electrical and mechanical parameter equivalence. The following criteria establish substitution validity:

Electrical Parameters (Must Match):

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 4.5 A
• Voltage - Collector Emitter Breakdown (Max): 12 V
• Vce Saturation (Max) @ Ib, Ic: 300mV @ 200mA, 5A
• Current - Collector Cutoff (Max): 50nA (ICBO)
• DC Current Gain (hFE) (Min) @ Ic, Vce: 300 @ 500mA, 1V
• Power - Max: 1.58 W
• Frequency - Transition: 80MHz
• Operating Temperature: -55°C to 200°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: E-Line-3, Formed Leads
• Supplier Device Package: E-Line (TO-92 compatible)

Compliance Parameters (Must Match):

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

Substitute parts identified in this reference maintain identical electrical and mechanical specifications. Packaging configuration (Tape & Box versus individual packaging) does not affect electrical or mechanical compatibility and does not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

The ZTX968STZ is a direct electrical and mechanical equivalent to the ZTX968STOA. All critical electrical parameters, including collector current rating, breakdown voltage, saturation characteristics, current gain, power dissipation, and frequency response, are identical. The physical package, mounting type, and lead configuration are identical.

The primary distinction between these parts is product status and packaging configuration. The ZTX968STOA is classified as obsolete, while the ZTX968STZ is an active product. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

For applications currently specified with the ZTX968STOA, the ZTX968STZ provides full functional and physical compatibility. The active product status of the ZTX968STZ ensures continued availability and supply chain support. Packaging configuration differences (Tape & Box versus individual packaging) do not affect component performance or circuit-level compatibility and reflect only distribution and handling methods.

Frequently Asked Questions (FAQ)

Q: Can the ZTX968STZ be used as a direct replacement for the ZTX968STOA in existing designs?

A: Yes. The ZTX968STZ is electrically and mechanically identical to the ZTX968STOA. All electrical parameters, including current rating, voltage rating, gain characteristics, and frequency response, are equivalent. The physical package, lead configuration, and mounting type are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between the ZTX968STOA and ZTX968STZ?

A: The parts are electrically and mechanically identical. The ZTX968STOA is classified as an obsolete product, while the ZTX968STZ is an active product. The ZTX968STZ is supplied in Tape & Box packaging, while the ZTX968STOA was supplied in individual packaging. These differences do not affect electrical performance or circuit compatibility.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the ZTX968STOA and ZTX968STZ maintain identical RoHS3 compliance status and moisture sensitivity ratings (MSL 1, Unlimited). Both parts are REACH Unaffected and carry the same ECCN and HTSUS classifications.

Q: Does the packaging configuration affect substitution?

A: No. Packaging configuration (Tape & Box versus individual packaging) reflects distribution and handling methods only. It does not affect electrical performance, mechanical compatibility, or circuit-level functionality. Both packaging configurations are suitable for through-hole assembly applications.

Q: Why is the ZTX968STOA classified as obsolete?

A: Product status classifications reflect manufacturer production and support decisions. The ZTX968STZ, as an active product from the same manufacturer with identical specifications, provides continued availability for applications requiring this component type and performance level.

Q: Can the ZTX968STZ be used in high-temperature applications?

A: Yes. The ZTX968STZ operates across the full temperature range of -55°C to 200°C (junction temperature), identical to the ZTX968STOA. This operating range supports applications requiring extended temperature performance.
