15C02MH-TL-E Equivalent & Substitute Parts

Part Overview

The 15C02MH-TL-E is an NPN bipolar junction transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. This device operates at a maximum collector current of 1 A with a collector-emitter breakdown voltage of 15 V and a maximum power dissipation of 600 mW. The transistor features a transition frequency of 440 MHz and is housed in a 3-MCPH surface mount package.

The 15C02MH-TL-E is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 15C02MH-TL-E is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor type must be NPN
• Collector-emitter breakdown voltage must be equal to or greater than 15 V
• Maximum collector current must be equal to or greater than 1 A
• DC current gain (hFE) must support the intended bias conditions
• Vce saturation characteristics must be compatible with switching applications

Mechanical Compatibility Criteria:

• Mounting type must be surface mount
• Package footprint must be compatible with existing PCB designs or acceptable for redesign

Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required

The 2SD1048-7-TB-E qualifies as a substitute part. While it exhibits reduced maximum collector current (700 mA versus 1 A), reduced power dissipation (200 mW versus 600 mW), and lower transition frequency (250 MHz versus 440 MHz), it maintains the required 15 V collector-emitter breakdown voltage, NPN configuration, surface mount technology, and full compliance certifications. The 2SD1048-7-TB-E is classified as active, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The 2SD1048-7-TB-E is the designated manufacturer-recommended substitute for the 15C02MH-TL-E. Selection of this substitute part is supported by the following factors:

Product Status: The 2SD1048-7-TB-E maintains active product status with onsemi, ensuring long-term availability and supply chain continuity. The 15C02MH-TL-E is obsolete, making substitution necessary for ongoing production support.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement and deployment.

Electrical Compatibility: The 2SD1048-7-TB-E maintains the 15 V collector-emitter breakdown voltage specification, ensuring compatibility with voltage-constrained circuit designs. The NPN configuration and surface mount technology are identical.

Performance Trade-offs: Applications requiring the full 1 A collector current or 600 mW power dissipation of the original part must be evaluated against the 700 mA and 200 mW ratings of the substitute. Similarly, designs dependent on the 440 MHz transition frequency must assess compatibility with the 250 MHz specification of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the 2SD1048-7-TB-E directly replace the 15C02MH-TL-E in all applications?

A: Direct replacement is possible only in applications where the collector current does not exceed 700 mA, power dissipation does not exceed 200 mW, and the transition frequency requirement does not exceed 250 MHz. Circuit designs operating at the maximum specifications of the 15C02MH-TL-E require evaluation and potential redesign.

Q: What are the package differences between these parts?

A: The 15C02MH-TL-E uses a 3-MCPH surface mount package with flat leads. The 2SD1048-7-TB-E uses a 3-CP package, which corresponds to the TO-236-3, SC-59, or SOT-23-3 standard. PCB footprint compatibility must be verified before substitution.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No regulatory barriers exist to substitution from a compliance perspective.

Q: What is the impact of the reduced DC current gain in the 2SD1048-7-TB-E?

A: The 2SD1048-7-TB-E specifies a minimum DC current gain (hFE) of 200 at 50 mA and 2 V, compared to 300 for the 15C02MH-TL-E. Bias network calculations and base current requirements must be re-evaluated to ensure proper circuit operation.

Q: How does the lower maximum operating temperature of the 2SD1048-7-TB-E affect suitability?

A: The 2SD1048-7-TB-E operates to a maximum junction temperature of 125°C, compared to 150°C for the 15C02MH-TL-E. Applications operating in high-temperature environments must verify that thermal management remains adequate with the reduced temperature rating.

Q: Is the 2SD1048-7-TB-E the only available substitute?

A: The 2SD1048-7-TB-E is the manufacturer-recommended substitute provided by onsemi. Additional equivalent parts may exist from other manufacturers; however, only the 2SD1048-7-TB-E is specified in the manufacturer's substitution guidance for this component.
