2N5772 Equivalent & Substitute Parts

Part Overview

The 2N5772 is an obsolete NPN bipolar junction transistor manufactured by onsemi, designed for through-hole applications in the TO-92-3 package. This device operates at a maximum collector voltage of 15 V with a collector current rating of 300 mA and maximum power dissipation of 350 mW. Due to its obsolete product status, identifying equivalent or substitute components is necessary for ongoing production support, maintenance, and design continuity in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

The provided substitute part SBH21-NBPN-D05-ST-BK is a rectangular connector header manufactured by Sullins Connector Solutions. This component belongs to a fundamentally different product category (Rectangular Connectors) compared to the 2N5772 (Transistors, Bipolar BJT).

A valid substitute for the 2N5772 must satisfy the following electrical and mechanical criteria:

• Transistor Type: NPN configuration
• Maximum Collector Current: 300 mA or greater
• Maximum Collector-Emitter Breakdown Voltage: 15 V or greater
• Maximum Power Dissipation: 350 mW or greater
• DC Current Gain (hFE): Minimum 30 at specified operating conditions
• Package Type: Through-hole compatible form factor (TO-92-3 or equivalent)
• Operating Temperature Range: Support for -55°C to 150°C or compatible subset

The SBH21-NBPN-D05-ST-BK does not meet these criteria and cannot function as an electrical substitute for the 2N5772 due to its classification as a connector component rather than a semiconductor transistor.

Parameter Comparison

Engineering Selection Recommendations

The SBH21-NBPN-D05-ST-BK listed as a substitute for the 2N5772 is not a valid electrical equivalent. The two components serve entirely different functions within electronic systems: the 2N5772 is a semiconductor transistor for signal amplification and switching, while the SBH21-NBPN-D05-ST-BK is a connector header for board-to-board or cable interconnection.

For applications requiring the 2N5772, component selection must be based on:

• Electrical Performance: Matching or exceeding the specified collector current (300 mA), breakdown voltage (15 V), power dissipation (350 mW), and current gain (hFE ≥ 30)
• Package Compatibility: Through-hole mounting in TO-92-3 or mechanically equivalent package
• Compliance Status: REACH and RoHS compliance for new designs; REACH Unaffected status acceptable for legacy support
• Temperature Range: Operating range of -55°C to 150°C or compatible subset

Given the obsolete status of the 2N5772, direct replacements should be sourced from active product lines offering equivalent NPN transistor specifications in compatible through-hole packages.

Frequently Asked Questions (FAQ)

Q: Can the SBH21-NBPN-D05-ST-BK replace the 2N5772 in my circuit?

A: No. The SBH21-NBPN-D05-ST-BK is a connector header and cannot function as a transistor. It is not electrically compatible with the 2N5772 and cannot perform signal amplification or switching functions.

Q: What makes a part a valid substitute for the 2N5772?

A: A valid substitute must be an NPN bipolar junction transistor with electrical ratings meeting or exceeding: 300 mA collector current, 15 V collector-emitter breakdown voltage, 350 mW power dissipation, and minimum hFE of 30. The package must support through-hole mounting compatible with TO-92-3 form factor.

Q: Why is the 2N5772 listed as obsolete?

A: The 2N5772 is no longer in active production by onsemi. Obsolete status indicates the manufacturer has discontinued this product line. Existing inventory may be available from authorized distributors, but long-term availability is not guaranteed.

Q: What is the operating temperature range for the 2N5772?

A: The 2N5772 operates from -55°C to 150°C (junction temperature). This range supports both industrial and extended-temperature applications.

Q: Are there compliance considerations when selecting a substitute?

A: Yes. The 2N5772 carries REACH Unaffected status and EAR99 export classification. Substitute components should maintain equivalent or superior compliance certifications. New designs should prioritize RoHS3 compliant alternatives where available.

Q: What is the package type for the 2N5772?

A: The 2N5772 uses the TO-92-3 (also designated TO-226AA) through-hole package, a three-lead configuration standard for discrete transistors. Substitutes must support equivalent mechanical and electrical pin compatibility.
