MPSA92RLRPG Equivalent & Substitute Parts

Part Overview

The MPSA92RLRPG 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 Through Hole TO-92 (TO-226-3) configuration with a maximum power dissipation of 625 mW and transition frequency of 50 MHz. The MPSA92RLRPG is classified as obsolete product status. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPSA92RLRPG is determined by electrical and mechanical parameter equivalence. All substitute parts must satisfy the following criteria:

Electrical Parameters (Critical for Substitution):

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

Mechanical Parameters (Determines Physical Compatibility):

• Mounting Type: Through Hole or Surface Mount
• Package / Case: TO-92-3 (Through Hole) or SOT-23-3 (Surface Mount)

Substitute parts are grouped into two categories: direct through-hole equivalents and surface-mount alternatives. Direct equivalents maintain identical electrical specifications and through-hole packaging. Surface-mount alternatives provide electrical equivalence with reduced power dissipation capability and different package form factor.

Parameter Comparison

Engineering Selection Recommendations

Direct Through-Hole Equivalents:

KSP92TA and MPSA92 PBFREE are direct electrical and mechanical equivalents to the MPSA92RLRPG. Both parts maintain identical electrical specifications across all critical parameters including voltage rating, current capacity, gain characteristics, and frequency response. Both substitute parts are classified as active product status, ensuring long-term availability. KSP92TA is manufactured by onsemi and carries ROHS3 compliance certification. MPSA92 PBFREE is manufactured by Central Semiconductor Corp and also carries ROHS3 compliance certification with an extended lower operating temperature limit of -65°C compared to the original -55°C specification.

Surface-Mount Alternative:

MMBTA92LT1G provides electrical equivalence with different mechanical packaging. This part is manufactured by onsemi in an active product status and carries ROHS3 compliance certification. The primary distinction is the SOT-23-3 surface-mount package and reduced maximum power dissipation of 300 mW compared to 625 mW for through-hole variants. This part is suitable for applications where surface-mount technology is employed and power dissipation requirements do not exceed 300 mW.

Selection between through-hole and surface-mount alternatives depends on circuit board assembly technology and thermal design requirements. All substitute parts maintain compliance with REACH regulations and carry appropriate RoHS certifications.

Frequently Asked Questions (FAQ)

Q: Can KSP92TA be used as a direct replacement for MPSA92RLRPG in existing designs?

A: Yes. KSP92TA is a direct electrical and mechanical equivalent. Both parts share identical electrical specifications including voltage rating (300 V), current capacity (500 mA), power dissipation (625 mW), and gain characteristics. Both use through-hole TO-92-3 packaging. KSP92TA is manufactured by onsemi and carries active product status with ROHS3 compliance.

Q: What is the primary difference between MPSA92 PBFREE and the original MPSA92RLRPG?

A: MPSA92 PBFREE is manufactured by Central Semiconductor Corp rather than onsemi, and carries an extended lower operating temperature limit of -65°C compared to -55°C for the original part. All electrical specifications and through-hole TO-92-3 packaging remain identical. MPSA92 PBFREE carries active product status and ROHS3 compliance.

Q: When should MMBTA92LT1G be selected instead of through-hole alternatives?

A: MMBTA92LT1G should be selected when the circuit board design employs surface-mount assembly technology and the application power dissipation requirement does not exceed 300 mW. This part maintains all electrical specifications of the original MPSA92RLRPG except for reduced maximum power dissipation. The SOT-23-3 package is not compatible with through-hole PCB layouts.

Q: Are all substitute parts RoHS compliant?

A: Yes. KSP92TA, MMBTA92LT1G, and MPSA92 PBFREE all carry ROHS3 compliance certification. All parts are also REACH unaffected.

Q: What is the impact of the reduced power rating on MMBTA92LT1G?

A: MMBTA92LT1G has a maximum power dissipation of 300 mW compared to 625 mW for through-hole variants. This reduced rating reflects the smaller physical size of the SOT-23-3 package. Applications requiring continuous power dissipation above 300 mW must use through-hole alternatives (KSP92TA or MPSA92 PBFREE).

Q: Can MMBTA92LT1G be used in a through-hole PCB design?

A: No. MMBTA92LT1G uses SOT-23-3 surface-mount packaging and cannot be directly installed in through-hole PCB layouts. Through-hole designs require KSP92TA or MPSA92 PBFREE.

Q: Are there any temperature range limitations when substituting parts?

A: KSP92TA specifies an upper operating temperature limit of 150°C without a stated lower limit. MPSA92 PBFREE extends the lower operating temperature to -65°C compared to -55°C for the original MPSA92RLRPG. MMBTA92LT1G maintains the original -55 to 150°C range. Verify application temperature requirements before selection.
