ECH8102-TL-H Equivalent & Substitute Parts

Part Overview

The ECH8102-TL-H is a PNP bipolar junction transistor manufactured by onsemi, rated for 30V collector-emitter breakdown voltage and 12A maximum collector current. This component is classified as obsolete, necessitating identification of active substitute parts for new designs and ongoing production requirements. The part is housed in an 8-SMD flat lead surface mount package and complies with RoHS3 and REACH regulations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH8102-TL-H is determined by the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor type must be PNP
• Voltage - Collector Emitter Breakdown must be ≥ 30V
• Current - Collector (Ic) must be ≥ 12A
• DC Current Gain (hFE) must be ≥ 200 @ 500mA, 2V
• Operating temperature must support ≥ 150°C (TJ)

Mechanical Compatibility Criteria:

• Mounting type must be Surface Mount
• Package must accommodate 8-SMD or equivalent footprint

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status required

The CPH6122-TL-E does not meet the electrical substitution criteria due to maximum collector current rating of 3A, which is below the 12A requirement of the ECH8102-TL-H. This part cannot function as a direct substitute in applications requiring the full 12A current capacity.

Parameter Comparison

Engineering Selection Recommendations

The ECH8102-TL-H is classified as obsolete. For applications currently using this component, alternative sourcing strategies must be evaluated based on circuit requirements.

The CPH6122-TL-E is an active product from onsemi with identical voltage and gain specifications. However, this part is rated for maximum collector current of 3A, compared to the 12A rating of the ECH8102-TL-H. Selection of the CPH6122-TL-E is appropriate only for applications where the required collector current does not exceed 3A.

Both parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs. The CPH6122-TL-E offers higher transition frequency (400MHz versus 140MHz), which may provide performance advantages in high-frequency applications within the 3A current limit.

For applications requiring the full 12A current capacity of the ECH8102-TL-H, alternative PNP transistors with equivalent or superior current ratings must be evaluated against the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the CPH6122-TL-E directly replace the ECH8102-TL-H in all applications?

A: No. The CPH6122-TL-E is rated for 3A maximum collector current, while the ECH8102-TL-H is rated for 12A. Direct substitution is limited to applications where collector current does not exceed 3A.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by transistor type (PNP), collector-emitter breakdown voltage (≥30V), maximum collector current (≥12A), DC current gain (≥200 @ 500mA, 2V), and operating temperature (≥150°C TJ).

Q: Are there package differences between these parts?

A: Yes. The ECH8102-TL-H uses an 8-SMD flat lead package, while the CPH6122-TL-E uses a SOT-23-6 thin package (6-CPH). These packages have different footprints and pin configurations, requiring PCB layout modifications.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the ECH8102-TL-H and CPH6122-TL-E are RoHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: Why is the ECH8102-TL-H classified as obsolete?

A: Product status is determined by the manufacturer. Obsolete classification indicates the part is no longer in active production, necessitating alternative component identification for ongoing supply and new designs.

Q: What is the significance of the higher transition frequency in the CPH6122-TL-E?

A: The CPH6122-TL-E operates at 400MHz transition frequency compared to 140MHz for the ECH8102-TL-H. This higher frequency capability may provide performance advantages in high-frequency switching applications, provided the 3A current limit is acceptable.
