MPSA92RA Equivalent & Substitute Parts

Part Overview

The MPSA92RA is a PNP bipolar junction transistor manufactured by onsemi, rated for 300 V collector-emitter breakdown voltage and 500 mA maximum collector current. This device is packaged in a TO-92-3 through-hole configuration and is designed for general-purpose switching and amplification applications. The MPSA92RA carries an obsolete product status, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the MPSA92RA is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

Electrical Parameters (Must Match):

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 500 mA
• Voltage - Collector Emitter Breakdown (Max): 300 V
• Vce Saturation (Max) @ Ib, Ic: 500mV @ 2mA, 20mA
• Current - Collector Cutoff (Max): 250nA (ICBO)
• DC Current Gain (hFE) (Min) @ Ic, Vce: 25 @ 30mA, 10V
• Power - Max: 625 mW
• Frequency - Transition: 50MHz

Mechanical Parameters (Must Match):

• Package / Case: TO-92-3 (TO-226AA) Formed Leads
• Mounting Type: Through Hole

The KSP92TA meets all electrical and mechanical substitution criteria and is manufactured by onsemi with active product status.

Parameter Comparison

Engineering Selection Recommendations

The KSP92TA is a direct electrical and mechanical equivalent to the MPSA92RA. Both devices are manufactured by onsemi and share identical electrical specifications across all critical parameters including collector current, breakdown voltage, saturation characteristics, current gain, power dissipation, and transition frequency. Both devices utilize the same TO-92-3 through-hole package configuration.

The primary distinction between these parts is product status: the MPSA92RA is obsolete, while the KSP92TA maintains active product status. The KSP92TA is ROHS3 compliant and carries REACH Unaffected certification, consistent with current regulatory requirements. Both parts share identical ECCN and HTSUS classifications.

For applications currently using the MPSA92RA, the KSP92TA provides full functional and mechanical compatibility without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the KSP92TA be used as a direct replacement for the MPSA92RA in existing designs?

A: Yes. The KSP92TA is electrically and mechanically identical to the MPSA92RA. All electrical parameters, including collector current rating, breakdown voltage, saturation voltage, current gain, power dissipation, and transition frequency are equivalent. The TO-92-3 through-hole package is identical, allowing direct board-level substitution without circuit modification.

Q: What is the primary reason to transition from MPSA92RA to KSP92TA?

A: The MPSA92RA is classified as obsolete. The KSP92TA is an active product from the same manufacturer with identical specifications, ensuring long-term availability and supply chain continuity.

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

A: The KSP92TA is ROHS3 compliant. Both parts are REACH Unaffected and share identical ECCN and HTSUS classifications. The KSP92TA meets current regulatory standards for electronic components.

Q: Does the packaging format differ between MPSA92RA and KSP92TA?

A: Both parts are supplied in TO-92-3 through-hole packages with formed leads. The MPSA92RA is available in standard packaging, while the KSP92TA is supplied in cut tape (CT) format. The physical component and pin configuration are identical; packaging format refers to the supply method only.

Q: Are the operating temperature ranges identical?

A: The MPSA92RA specifies an operating temperature range of -55°C to 150°C (TJ). The KSP92TA specifies a maximum operating temperature of 150°C (TJ). Both parts support the same upper temperature limit. For applications requiring the full -55°C lower limit, both parts are suitable.
