2SA1013-R-AP Equivalent & Substitute Parts

Part Overview

The 2SA1013-R-AP is a PNP bipolar junction transistor manufactured by Micro Commercial Co, rated for 160 V collector-emitter breakdown voltage and 1 A maximum collector current. This device is packaged in a TO-92MOD through-hole configuration and is rated for 900 mW maximum power dissipation with a transition frequency of 15 MHz. The 2SA1013-R-AP is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, power dissipation, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SA1013-R-AP is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor type must be PNP
• Maximum collector current (Ic) must be ≥ 1 A
• Maximum collector-emitter breakdown voltage (Vceo) must be ≥ 160 V
• Maximum power dissipation must be ≥ 900 mW
• DC current gain (hFE) minimum must be ≥ 60 @ 200mA, 5V
• Vce saturation characteristics must be ≤ 1.5V @ 50mA, 500mA

Mechanical Equivalence Criteria:

• Package must be TO-92-3 or TO-226-3 (through-hole compatible)
• Mounting type must be through-hole

Compliance Criteria:

• RoHS3 compliance required
• ECCN and HTSUS classifications must align

The KSA1013YBU meets all substitution criteria and is classified as an active product, providing long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The KSA1013YBU is a direct functional substitute for the 2SA1013-R-AP. Both devices share identical electrical ratings across all critical parameters: 1 A maximum collector current, 160 V breakdown voltage, 900 mW power dissipation, and 60 minimum DC current gain. Both are packaged in TO-92-3 through-hole configuration and maintain RoHS3 compliance.

The primary advantage of selecting the KSA1013YBU is its active product status. The 2SA1013-R-AP is classified as obsolete, which creates supply chain risk and limits long-term availability. The KSA1013YBU, manufactured by onsemi, is an active product with 28,100 units in stock, ensuring production continuity and supply reliability.

The KSA1013YBU exhibits superior performance characteristics in two areas: transition frequency (50 MHz versus 15 MHz) and collector cutoff current (1 µA versus 10 µA). These improvements do not create compatibility issues and represent enhanced device performance. Both devices operate across the same temperature range (-55°C to 150°C junction temperature for the main part; 150°C maximum for the substitute).

Selection of the KSA1013YBU is appropriate for all applications currently using the 2SA1013-R-AP without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the KSA1013YBU be used as a direct replacement for the 2SA1013-R-AP without circuit modification?

A: Yes. The KSA1013YBU meets all electrical and mechanical specifications of the 2SA1013-R-AP. Identical ratings for collector current, breakdown voltage, power dissipation, saturation voltage, and current gain ensure functional equivalence. Both devices use the same TO-92-3 through-hole package with identical pin configuration.

Q: What is the significance of the higher transition frequency in the KSA1013YBU?

A: The KSA1013YBU operates at 50 MHz transition frequency compared to 15 MHz for the 2SA1013-R-AP. This represents improved high-frequency performance and does not create compatibility issues. Applications operating below 15 MHz experience no change in behavior. Applications requiring higher frequency response benefit from the enhanced specification.

Q: Why is the collector cutoff current lower in the KSA1013YBU?

A: The KSA1013YBU specifies 1 µA maximum collector cutoff current (ICBO) versus 10 µA for the 2SA1013-R-AP. Lower leakage current represents improved device quality and does not affect circuit operation. This specification is superior and does not create compatibility concerns.

Q: Are both devices RoHS compliant?

A: Yes. Both the 2SA1013-R-AP and KSA1013YBU are ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing and restricted substance limitations.

Q: What is the difference between TO-92MOD and TO-92-3 packaging?

A: Both designations refer to the same three-lead through-hole package configuration. TO-92MOD is the supplier device package designation for the 2SA1013-R-AP, while TO-92-3 is the standard package classification. The physical form factor, lead spacing, and mounting characteristics are identical, ensuring mechanical compatibility.

Q: Why should I select the KSA1013YBU over the 2SA1013-R-AP?

A: The 2SA1013-R-AP is classified as obsolete, creating supply chain risk and limiting future availability. The KSA1013YBU is an active product with substantial inventory (28,100 units), ensuring reliable supply for current and future production. The KSA1013YBU also provides superior performance characteristics without requiring circuit changes.

Q: Are there any temperature operating range differences?

A: The 2SA1013-R-AP operates from -55°C to 150°C junction temperature. The KSA1013YBU specifies 150°C maximum junction temperature. For applications operating above -55°C, both devices are equivalent. Applications requiring operation below -55°C must retain the 2SA1013-R-AP or identify alternative solutions.

Q: Can I use the KSA1013YBU in legacy designs currently using the 2SA1013-R-AP?

A: Yes. The KSA1013YBU is a direct substitute for legacy designs. No circuit modifications, PCB changes, or design re-qualification are required. The identical electrical specifications and package form factor ensure drop-in compatibility.
