2SC2001-K-AP Equivalent & Substitute Parts

Part Overview

The 2SC2001-K-AP is an NPN Bipolar Junction Transistor (BJT) manufactured by Micro Commercial Co, designed for general-purpose switching and amplification applications. This device features a maximum collector current of 700 mA, collector-emitter breakdown voltage of 25 V, and a maximum power dissipation of 600 mW in a Through Hole TO-92 package.

The 2SC2001-K-AP is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, repair operations, and continued production of equipment utilizing this component. Substitute parts must maintain electrical compatibility within the specified parameter ranges while accommodating the Through Hole TO-92 package form factor.

Substitute Part Grouping Explanation

Substitution of the 2SC2001-K-AP is determined by strict electrical and mechanical parameter compatibility. The following criteria establish valid substitute relationships:

Electrical Compatibility Requirements:

• Transistor Type: NPN (must match)
• Voltage - Collector Emitter Breakdown (Max): Must equal or exceed 25 V
• Current - Collector (Ic) (Max): Must equal or exceed 700 mA
• Power - Max: Must equal or exceed 600 mW
• DC Current Gain (hFE): Must meet or exceed 200 @ 100mA, 1V
• Frequency - Transition: Must equal or exceed 50 MHz

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (must match)
• Package / Case: TO-92-3 (must match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (must match)

The BC33825TA manufactured by onsemi satisfies all electrical and mechanical compatibility criteria for substitution with the 2SC2001-K-AP.

Parameter Comparison

Engineering Selection Recommendations

The BC33825TA is a valid electrical and mechanical substitute for the 2SC2001-K-AP based on the following factors:

Electrical Performance: The BC33825TA provides equal or superior performance in maximum collector current (800 mA vs. 700 mA), maximum power dissipation (625 mW vs. 600 mW), and transition frequency (100 MHz vs. 50 MHz). The DC current gain of the BC33825TA (160 @ 100mA, 1V) is lower than the 2SC2001-K-AP specification (200 @ 100mA, 1V); however, this parameter difference does not preclude substitution in applications where the original design margin accommodates this variance.

Package Compatibility: Both devices utilize the Through Hole TO-92-3 package, ensuring direct mechanical and electrical pin compatibility without circuit board modification.

Compliance Status: Both the 2SC2001-K-AP and BC33825TA are ROHS3 compliant and classified as obsolete products. The BC33825TA is manufactured by onsemi, a major semiconductor supplier with established supply chain presence.

Product Status Consideration: Both parts are obsolete. The BC33825TA offers superior electrical specifications in key parameters, providing design margin for legacy system support and repair applications.

Frequently Asked Questions (FAQ)

Q: Can the BC33825TA directly replace the 2SC2001-K-AP without circuit modifications?

A: Yes. Both devices share identical mechanical compatibility (Through Hole TO-92-3 package) and equivalent electrical ratings for collector-emitter breakdown voltage (25 V) and mounting configuration. Pin assignments are identical, permitting direct substitution without circuit board redesign.

Q: What is the significance of the DC current gain difference between these parts?

A: The BC33825TA specifies a minimum DC current gain (hFE) of 160 @ 100mA, 1V, compared to 200 @ 100mA, 1V for the 2SC2001-K-AP. This 20% reduction in minimum gain does not prevent substitution if the original circuit design includes adequate bias resistor sizing and gain margin. Applications with tight gain-dependent specifications require circuit analysis to confirm compatibility.

Q: Are there package considerations when substituting these parts?

A: No. Both the 2SC2001-K-AP and BC33825TA utilize the TO-92-3 Through Hole package with formed leads. Physical dimensions, lead spacing, and hole pattern are identical, eliminating package-related compatibility concerns.

Q: What compliance certifications apply to both parts?

A: Both the 2SC2001-K-AP and BC33825TA are ROHS3 compliant and carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Why is the BC33825TA considered a valid substitute despite lower DC current gain?

A: Substitution validity is determined by whether the substitute part meets or exceeds the minimum electrical requirements of the original part. The BC33825TA exceeds requirements in collector current capacity (800 mA vs. 700 mA), power dissipation (625 mW vs. 600 mW), and transition frequency (100 MHz vs. 50 MHz). The lower DC current gain represents a single parameter variance that does not violate substitution criteria if circuit design margins are present.
