2N4410_D75Z Equivalent & Substitute Parts

Part Overview

The 2N4410_D75Z is an NPN bipolar junction transistor (BJT) manufactured by onsemi, rated for 80 V collector-emitter breakdown voltage and 200 mA maximum collector current in a TO-92-3 through-hole package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility within the specified voltage, current, and thermal operating ranges while accommodating the through-hole TO-92-3 package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N4410_D75Z is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute must support a minimum collector-emitter breakdown voltage of 80 V to maintain circuit protection margins. Parts rated below 80 V are not suitable for direct substitution.

Current Rating: The substitute must support a minimum collector current rating of 200 mA. Parts with higher current ratings (such as 500 mA) are acceptable as they provide design margin without compromising performance.

Power Dissipation: The substitute must support a minimum power rating of 625 mW to ensure thermal stability under specified operating conditions.

Package Form Factor: The substitute must utilize the TO-92-3 through-hole package to ensure mechanical compatibility with existing printed circuit board layouts and assembly processes.

Operating Temperature Range: The substitute must support the full operating temperature range of -55°C to 150°C (junction temperature).

Transistor Type: The substitute must be an NPN-type bipolar junction transistor to maintain circuit polarity and biasing requirements.

Parts meeting all six criteria are classified as direct substitutes. Parts that exceed the voltage or current ratings while maintaining the same package and temperature specifications are classified as compatible upgrades.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MPSA06RA (onsemi)

The MPSA06RA is the preferred substitute for the 2N4410_D75Z. This part maintains the 80 V collector-emitter breakdown voltage specification and exceeds the 200 mA current requirement with a 500 mA rating. The MPSA06RA is currently in active product status, ensuring long-term availability and supply chain continuity. The part is ROHS3 compliant and carries REACH unaffected certification. The TO-92-3 package form factor provides direct mechanical compatibility with existing circuit board layouts.

Secondary Substitute: MPSA06-AP (Micro Commercial Co)

The MPSA06-AP provides equivalent electrical specifications to the MPSA06RA, maintaining 80 V breakdown voltage and 500 mA current capability. However, this part is classified as obsolete, limiting its suitability for new designs requiring long-term component availability. The MPSA06-AP is ROHS3 compliant and carries REACH unaffected certification. The TO-92 package is mechanically compatible with TO-92-3 applications.

Not Recommended: 2N3904-AP and 2N4401-AP

The 2N3904-AP and 2N4401-AP are not suitable substitutes for the 2N4410_D75Z. Both parts are rated for 40 V maximum collector-emitter breakdown voltage, which is insufficient for circuits designed for 80 V operation. These parts do not meet the voltage specification requirement and introduce circuit reliability risk.

Frequently Asked Questions (FAQ)

Q: Can the MPSA06RA directly replace the 2N4410_D75Z in existing circuit designs?

A: Yes. The MPSA06RA maintains the 80 V collector-emitter breakdown voltage and exceeds the 200 mA current requirement. The TO-92-3 package provides identical pin configuration and mechanical fit. The part is currently in active production status, supporting long-term design continuity.

Q: What is the difference between MPSA06RA and MPSA06-AP?

A: Both parts provide identical electrical specifications: 80 V breakdown voltage, 500 mA maximum collector current, and 625 mW power dissipation. The primary difference is product status. The MPSA06RA (onsemi) is active, while the MPSA06-AP (Micro Commercial Co) is obsolete. For new designs, the MPSA06RA is preferred due to availability assurance.

Q: Why are 2N3904-AP and 2N4401-AP not suitable substitutes?

A: Both parts are rated for 40 V maximum collector-emitter breakdown voltage, which is 50% below the 80 V requirement of the 2N4410_D75Z. Using these parts in circuits designed for 80 V operation creates unacceptable reliability risk through voltage overstress conditions.

Q: Are there package compatibility considerations between TO-92-3 and TO-92?

A: The TO-92-3 and TO-92 packages are mechanically compatible for through-hole mounting applications. Both utilize three leads in identical pin spacing and hole diameter specifications. Circuit board layout modifications are not required for package substitution.

Q: What compliance certifications apply to substitute parts?

A: The MPSA06RA carries ROHS3 compliance and REACH unaffected certification. The MPSA06-AP, 2N3904-AP, and 2N4401-AP are all ROHS3 compliant with REACH unaffected status. All parts support -55°C to 150°C operating temperature range requirements.

Q: Does the higher current rating of MPSA06 parts affect circuit performance?

A: No. The 500 mA current rating of MPSA06 parts provides design margin without degrading circuit performance. The transistor will operate within its specified electrical characteristics at the 200 mA operating point of the original 2N4410_D75Z design.
