KSD882OS Equivalent & Substitute Parts

Part Overview

The KSD882OS is an NPN bipolar junction transistor manufactured by onsemi, rated for 30V collector-emitter breakdown voltage and 3A maximum collector current. This component is designed for through-hole mounting in the TO-126-3 package and operates across a temperature range of -55°C to 150°C. The KSD882OS is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSD882OS is determined by the following critical parameters:

1. Transistor Type: Must be NPN configuration
2. Voltage Rating: Collector-emitter breakdown voltage must be 30V or greater
3. Current Rating: Maximum collector current must be 3A or greater
4. Package Compatibility: Must support through-hole mounting in TO-126-3 or equivalent package footprint
5. Operating Temperature Range: Must encompass or exceed -55°C to 150°C
6. Power Dissipation: Must support minimum 1W power rating

The substitute parts KSD882YS and 2SD882 meet these electrical and mechanical requirements, enabling direct functional replacement in circuit applications designed for the KSD882OS.

Parameter Comparison

Engineering Selection Recommendations

KSD882YS is the primary substitute for KSD882OS. Both components are manufactured by onsemi with identical electrical specifications including 30V breakdown voltage, 3A collector current, and 1W power rating. The KSD882YS maintains the same TO-126-3 package configuration and operating temperature range. The KSD882YS is classified as Last Time Buy, indicating continued availability with defined procurement windows. The KSD882YS achieves ROHS3 compliance, providing regulatory advantage over the obsolete KSD882OS.

2SD882 is an alternative substitute manufactured by STMicroelectronics. This component meets all critical electrical parameters: 30V breakdown voltage, 3A collector current, and TO-126-3 package compatibility. The 2SD882 offers enhanced power dissipation capability at 12.5W compared to 1W for the KSD882OS, providing thermal margin in power-limited applications. The 2SD882 is classified as Active product status with high inventory availability (30,200 pieces), ensuring long-term supply continuity. The 2SD882 is ROHS3 compliant. The 2SD882 exhibits higher saturation voltage (1.1V versus 500mV) and higher collector cutoff current (100µA versus 1µA), which may require circuit verification in applications with stringent saturation or leakage specifications.

Frequently Asked Questions (FAQ)

Q: Can KSD882YS directly replace KSD882OS without circuit modification?

A: Yes. The KSD882YS maintains identical electrical specifications and package configuration as the KSD882OS. Both components share the same 30V breakdown voltage, 3A collector current, 1W power rating, 90MHz transition frequency, and TO-126-3 package. Direct substitution is supported without circuit redesign.

Q: What are the differences between KSD882YS and 2SD882?

A: Both components meet the core electrical requirements of 30V breakdown voltage and 3A collector current. The primary differences are: (1) Power dissipation: 2SD882 rated at 12.5W versus 1W for KSD882YS; (2) Saturation voltage: 2SD882 exhibits 1.1V at 3A versus 500mV at 2A for KSD882YS; (3) Collector cutoff current: 2SD882 at 100µA versus 1µA for KSD882YS; (4) Manufacturer: STMicroelectronics (2SD882) versus onsemi (KSD882YS); (5) Product status: 2SD882 is Active versus Last Time Buy for KSD882YS.

Q: Are there package compatibility concerns when substituting these parts?

A: All three components utilize the TO-126-3 package with identical through-hole mounting configuration. Package footprints are compatible, and no PCB layout modifications are required for substitution.

Q: Which substitute should be selected for new designs?

A: The 2SD882 is recommended for new designs due to Active product status, ensuring long-term availability and supply chain stability. The 2SD882 provides superior power dissipation capability and higher inventory levels (30,200 pieces). The KSD882YS is suitable for legacy system maintenance and repair applications where onsemi sourcing is preferred.

Q: Does the higher power rating of 2SD882 affect circuit operation?

A: The 2SD882 power rating of 12.5W exceeds the 1W requirement of the KSD882OS. Higher power rating does not negatively affect circuit operation; it provides additional thermal margin. However, the 2SD882 exhibits different saturation characteristics (1.1V at 3A versus 500mV at 2A), which may impact circuits with tight saturation voltage specifications. Circuit verification is necessary in applications where saturation voltage is a critical design parameter.

Q: What is the significance of the Last Time Buy status for KSD882YS?

A: Last Time Buy status indicates that onsemi has announced end-of-life for the KSD882YS with a defined final purchase date. Inventory is available but will not be replenished after the Last Time Buy window closes. For applications requiring long-term supply continuity, transition to the 2SD882 is recommended.

Q: Are there compliance differences between the substitute parts?

A: The KSD882OS is REACH Unaffected. Both KSD882YS and 2SD882 are ROHS3 Compliant, providing enhanced regulatory compliance for applications subject to RoHS directives. All three components are classified as EAR99 for export control purposes.
