2SA1162-O-AP Equivalent & Substitute Parts

Part Overview

The 2SA1162-O-AP is a PNP bipolar junction transistor manufactured by Micro Commercial Co, designed for surface mount applications in the SOT-23 package. This component operates at a maximum collector current of 150 mA with a 50 V collector-emitter breakdown voltage and 150 mW power dissipation capability. The device is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SA1162-O-AP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 150 mA
• Voltage - Collector Emitter Breakdown (Max): 50 V
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variations:

• Power dissipation may exceed 150 mW
• Transition frequency may exceed 80 MHz
• DC Current Gain (hFE) may exceed minimum specifications
• Operating temperature maximum may exceed 150°C
• Product status may transition from obsolete to active

The substitute parts 2SA1037AKT146Q, 2SA1037AKT146R, and 2SA1162S-Y,LF meet all critical matching parameters and are therefore qualified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

2SA1037AKT146Q (Rohm Semiconductor)

This substitute is an active product with ROHS3 compliance and unlimited moisture sensitivity rating. It provides enhanced power dissipation (200 mW versus 150 mW) and higher transition frequency (140 MHz versus 80 MHz). The higher DC current gain (120 @ 1mA, 6V) and increased Vce saturation voltage (500mV @ 5mA, 50mA) are within acceptable tolerance for applications designed for the 2SA1162-O-AP. Inventory availability is 181,400 units.

2SA1037AKT146R (Rohm Semiconductor)

This substitute is an active product with ROHS3 compliance and unlimited moisture sensitivity rating. It provides the same electrical enhancements as the 2SA1037AKT146Q with superior DC current gain (180 @ 1mA, 6V). This part offers the highest inventory availability at 702,200 units, supporting long-term procurement requirements. The SMT3 package designation is mechanically compatible with SOT-23-3 specifications.

2SA1162S-Y,LF (Toshiba Semiconductor and Storage)

This substitute is an active product with RoHS compliance and unlimited moisture sensitivity rating. It maintains identical electrical characteristics to the 2SA1162-O-AP, including 150 mW power dissipation and 80 MHz transition frequency. The S-Mini package is mechanically compatible with SOT-23-3 specifications. Operating temperature maximum is 125°C, which is lower than the original part's 150°C specification. Inventory availability is 889 units.

Frequently Asked Questions (FAQ)

Q: Can the 2SA1037AKT146Q or 2SA1037AKT146R be used as direct replacements for the 2SA1162-O-AP?

A: Yes. Both parts meet all critical electrical and mechanical parameters: 150 mA maximum collector current, 50 V collector-emitter breakdown voltage, SOT-23-3 package compatibility, surface mount mounting type, and ROHS3 compliance. The higher power dissipation and transition frequency represent performance enhancements rather than incompatibilities.

Q: What is the difference between the 2SA1037AKT146Q and 2SA1037AKT146R?

A: Both parts are manufactured by Rohm Semiconductor with identical electrical ratings except for DC current gain. The 2SA1037AKT146R has a minimum DC current gain of 180 @ 1mA, 6V, compared to 120 @ 1mA, 6V for the 2SA1037AKT146Q. Both are qualified substitutes for the 2SA1162-O-AP.

Q: Is the 2SA1162S-Y,LF suitable for applications requiring the full -55°C to 150°C operating temperature range?

A: The 2SA1162S-Y,LF has a maximum operating temperature of 125°C, which is lower than the 2SA1162-O-AP specification of 150°C. Applications requiring operation above 125°C must use the 2SA1037AKT146Q or 2SA1037AKT146R, which support 150°C operation.

Q: Are the SMT3 and S-Mini package designations compatible with SOT-23-3 footprints?

A: Yes. All substitute parts are specified with TO-236-3, SC-59, SOT-23-3 package compatibility. The SMT3 and S-Mini designations are supplier-specific package identifiers for the same physical form factor.

Q: What is the inventory status of these substitute parts?

A: The 2SA1037AKT146R has the highest availability at 702,200 units. The 2SA1037AKT146Q has 181,400 units available. The 2SA1162S-Y,LF has 889 units available. All three parts are active products with ongoing supply.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 2SA1037AKT146Q and 2SA1037AKT146R are ROHS3 compliant. The 2SA1162S-Y,LF is RoHS compliant. All parts meet environmental compliance requirements for restricted substance use.
