KSD882YSTSTU Equivalent & Substitute Parts

Part Overview

The KSD882YSTSTU is an NPN bipolar junction transistor manufactured by onsemi, rated for 30V collector-emitter breakdown voltage and 3A maximum collector current. This component is packaged in TO-126-3 through-hole configuration and is currently classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and system maintenance applications.

Substitute Part Grouping Explanation

Substitution of the KSD882YSTSTU is determined by electrical and mechanical parameter compatibility within the NPN bipolar transistor category. The critical parameters governing substitution are:

Electrical Parameters:

Collector current rating (3A maximum)
Collector-emitter breakdown voltage (30V maximum)
Power dissipation capability (1W minimum)
DC current gain characteristics
Saturation voltage performance

Mechanical Parameters:

Through-hole mounting compatibility
TO-126-3 package footprint compatibility

Substitute parts are grouped into two categories based on parameter alignment:

Direct Equivalents: Parts with identical electrical specifications and package compatibility, differing only in packaging format (bulk, tube) or product status.

Similar Equivalents: Parts with compatible electrical ratings and through-hole mounting but with variations in secondary parameters such as power dissipation, transition frequency, or saturation voltage characteristics.

Engineering Selection Recommendations

KSD882YS (Direct Equivalent - Last Time Buy): This part is a direct electrical equivalent to the KSD882YSTSTU with identical specifications across all critical parameters. The primary difference is packaging format (bulk versus tube). This part carries Last Time Buy status, indicating limited future availability. Selection of this part is appropriate for applications requiring exact parameter matching with near-term procurement windows.

KSD882YSTU (Direct Equivalent - Active): This part is a direct electrical equivalent to the KSD882YSTSTU with identical specifications across all critical parameters. The primary difference is packaging format (tube versus the original packaging). This part maintains Active product status with ROHS3 compliance certification. This is the recommended selection for new designs and ongoing production requiring direct parameter equivalence with assured long-term availability.

2SD882 (Similar Equivalent - Active): This STMicroelectronics part maintains compatibility with the primary electrical ratings (3A collector current, 30V breakdown voltage) and through-hole mounting configuration. Differences exist in secondary parameters: maximum power dissipation (12.5W versus 1W), transition frequency (100MHz versus 90MHz), DC current gain (100 versus 160 @ different test conditions), and saturation voltage (1.1V versus 500mV). This part is suitable for applications where the higher power rating and improved thermal characteristics provide design margin, provided the saturation voltage and gain characteristics are compatible with circuit requirements. Active product status and ROHS3 compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can KSD882YSTU be used as a direct replacement for KSD882YSTSTU?

A: Yes. KSD882YSTU is a direct electrical equivalent with identical collector current (3A), collector-emitter breakdown voltage (30V), power rating (1W), transition frequency (90MHz), DC current gain (160 @ 1A, 2V), and saturation voltage (500mV @ 200mA, 2A) specifications. The difference is packaging format (tube). Both use TO-126-3 through-hole package with identical pinout and footprint compatibility.

Q: What is the difference between KSD882YS and KSD882YSTU?

A: Both parts are direct electrical equivalents with identical specifications. The difference is packaging format: KSD882YS is supplied in bulk packaging, while KSD882YSTU is supplied in tube packaging. KSD882YSTU maintains Active product status, while KSD882YS is Last Time Buy.

Q: Can 2SD882 replace KSD882YSTSTU in all applications?

A: 2SD882 is compatible for applications where the primary requirements are 3A collector current and 30V breakdown voltage with through-hole mounting. However, differences in secondary parameters must be evaluated: 2SD882 has higher power dissipation (12.5W), higher transition frequency (100MHz), lower DC current gain (100 @ 100mA, 2V versus 160 @ 1A, 2V), and higher saturation voltage (1.1V @ 150mA, 3A versus 500mV @ 200mA, 2A). Circuit designs dependent on specific gain or saturation voltage characteristics require verification of compatibility.

Q: Are all substitute parts RoHS compliant?

A: KSD882YS, KSD882YSTU, and 2SD882 are all ROHS3 compliant. The original KSD882YSTSTU carries REACH Unaffected status. All parts are REACH compliant.

Q: What is the recommended substitute for new designs?

A: KSD882YSTU is recommended for new designs. It maintains Active product status, ROHS3 compliance, and direct electrical equivalence to the original KSD882YSTSTU specification with assured long-term availability.

Q: Are the packages physically compatible?

A: KSD882YSTSTU, KSD882YS, and KSD882YSTU all use TO-126-3 through-hole package with identical pinout and PCB footprint. 2SD882 uses SOT-32 (TO-126) package, which is mechanically compatible with TO-126-3 footprints in through-hole applications, though pin configuration should be verified for specific circuit layouts.
