BD882-O-TP Equivalent & Substitute Parts

Part Overview

The BD882-O-TP is an NPN bipolar junction transistor manufactured by Micro Commercial Co, designed for interface applications requiring moderate current switching and amplification. This surface mount device operates at 30 V maximum collector-emitter breakdown voltage with a 3 A maximum collector current rating and 500 mW power dissipation capability. The part is currently active in production with 1085 units in stock.

Substitute parts are identified to provide design flexibility when the primary part is unavailable, when alternative packaging formats are preferred, or when enhanced performance characteristics within the same electrical envelope are beneficial for system optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the BD882-O-TP is determined by strict equivalence across the following critical electrical parameters:

Primary Substitution Criteria:

Transistor type: NPN configuration
Maximum collector current: 3 A or greater
Maximum collector-emitter breakdown voltage: 30 V or greater
Maximum power dissipation: 500 mW or greater
Mounting type: Surface mount
Package compatibility: TO-243AA or equivalent footprint

Secondary Compatibility Factors:

Operating temperature range must encompass or exceed -55°C to 150°C
Transition frequency and DC current gain characteristics may vary without affecting basic substitution validity, provided primary electrical ratings are met

The 2SCR552P5T100 from Rohm Semiconductor meets all primary substitution criteria and is therefore classified as a direct electrical equivalent.

Engineering Selection Recommendations

Both the BD882-O-TP and 2SCR552P5T100 are active production parts with equivalent electrical ratings for the primary switching and amplification parameters. Selection between these parts is based on the following factors:

BD882-O-TP Selection Criteria:

Bulk packaging format is preferred for high-volume manufacturing environments
Lower transition frequency (50 MHz) is sufficient for lower-speed interface applications
Micro Commercial Co supply chain availability is prioritized

2SCR552P5T100 Selection Criteria:

Cut Tape and Digi-Reel packaging formats support automated pick-and-place assembly
Higher transition frequency (280 MHz) provides performance margin for higher-speed switching applications
RoHS3 compliance and MSL Level 1 rating provide enhanced environmental and moisture handling specifications
Rohm Semiconductor supply chain availability is prioritized
Superior DC current gain (200 vs. 60) and lower collector cutoff current (1 µA vs. 10 µA) indicate tighter device characteristics

Both parts carry REACH Unaffected and EAR99 ECCN classifications, confirming equivalent regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 2SCR552P5T100 directly replace the BD882-O-TP in existing designs?

A: Yes. Both devices share identical maximum electrical ratings for collector current (3 A), collector-emitter breakdown voltage (30 V), and power dissipation (500 mW). The TO-243AA package footprint is identical. The 2SCR552P5T100 exhibits superior performance characteristics including higher transition frequency and improved DC current gain, making it a direct electrical substitute.

Q: What are the packaging differences between these parts?

A: The BD882-O-TP is supplied in Bulk packaging, while the 2SCR552P5T100 is available in Cut Tape (CT) and Digi-Reel formats. Both use the same TO-243AA physical package (SOT-89 and MPT3 are equivalent designations). Packaging format selection depends on assembly process requirements rather than electrical compatibility.

Q: Are there performance differences that affect circuit operation?

A: The 2SCR552P5T100 provides enhanced performance margins. Transition frequency is 280 MHz versus 50 MHz, and DC current gain is 200 versus 60 at specified test conditions. Collector cutoff current is lower (1 µA vs. 10 µA). These differences indicate tighter device characteristics and improved high-frequency performance, but do not prevent substitution in applications designed for the BD882-O-TP.

Q: What is the operating temperature range for both parts?

A: Both devices operate from -55°C to 150°C junction temperature, providing identical thermal operating envelopes for system design.

Q: Are there compliance or certification differences?

A: The 2SCR552P5T100 carries RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, providing additional environmental specifications. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: Which part should be selected for new designs?

A: Selection is based on supply chain availability, packaging format requirements, and performance margin preferences. The 2SCR552P5T100 offers higher transition frequency and improved device characteristics suitable for designs requiring performance headroom. The BD882-O-TP remains valid for applications where the specified 50 MHz transition frequency is adequate.
