CPH3205-M-TL-E Equivalent & Substitute Parts

Part Overview

The CPH3205-M-TL-E is an NPN bipolar junction transistor manufactured by onsemi, rated for 50 V collector-emitter breakdown voltage and 3 A maximum collector current. This device is packaged in a Surface Mount TO-236-3 (SOT-23-3) configuration and operates at a transition frequency of 380 MHz with a maximum power dissipation of 900 mW.

The CPH3205-M-TL-E carries an Obsolete product status. Locating equivalent or substitute components is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPH3205-M-TL-E is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor Type: NPN configuration required
• Voltage - Collector Emitter Breakdown (Max): Must equal or exceed 50 V
• Current - Collector (Ic) (Max): Must equal or exceed 3 A
• Power - Max: Must equal or exceed 900 mW
• Vce Saturation: Lower values indicate improved performance
• DC Current Gain (hFE): Minimum 200 at specified conditions ensures functional equivalence
• Frequency - Transition: Must support 380 MHz operation or higher

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Package / Case: TO-236-3, SC-59, or SOT-23-3 compatible footprints

Compliance Requirements:

• RoHS3 Compliant status
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are classified into two categories: MFR Recommended substitutes (manufacturer-endorsed alternatives) and Similar parts (components meeting electrical and mechanical specifications with active product status).

Parameter Comparison

Engineering Selection Recommendations

NSS60201LT1G (MFR Recommended Substitute):

The NSS60201LT1G is designated as the manufacturer-recommended substitute for the CPH3205-M-TL-E. This part carries Active product status, ensuring long-term availability and supply chain continuity. Both devices are ROHS3 Compliant with MSL 1 (Unlimited) ratings, confirming equivalent environmental and handling requirements.

The NSS60201LT1G provides a higher collector-emitter breakdown voltage (60 V versus 50 V), offering improved voltage margin. However, the maximum collector current is reduced to 2 A compared to the original 3 A specification. The transition frequency is lower at 100 MHz versus 380 MHz. Selection of this substitute is appropriate for applications where the 2 A current rating and 100 MHz frequency are sufficient for the intended circuit function.

CPH3216-TL-EX (Similar Alternative):

The CPH3216-TL-EX is an active onsemi product sharing identical voltage and power specifications with the CPH3205-M-TL-E. This part maintains the 50 V collector-emitter breakdown voltage and 900 mW power dissipation. The transition frequency is slightly higher at 420 MHz. The primary limitation is the reduced maximum collector current of 1 A, making this substitute suitable only for applications requiring lower current levels.

Both substitute parts maintain full compliance with RoHS3 and MSL 1 requirements, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the NSS60201LT1G directly replace the CPH3205-M-TL-E in all applications?

A: The NSS60201LT1G is the manufacturer-recommended substitute and shares the same package footprint (TO-236-3, SOT-23-3). However, the maximum collector current is 2 A versus 3 A on the original part. Direct replacement is valid only if the circuit design operates at or below 2 A collector current. The lower transition frequency (100 MHz versus 380 MHz) must also be evaluated against circuit frequency requirements.

Q: What are the key differences between the NSS60201LT1G and CPH3216-TL-EX?

A: The NSS60201LT1G provides higher voltage rating (60 V versus 50 V) and higher current capability (2 A versus 1 A). The CPH3216-TL-EX offers higher transition frequency (420 MHz versus 100 MHz) and maintains the original 900 mW power rating. Selection depends on whether the application is current-limited or frequency-limited.

Q: Are all substitute parts compatible with the original PCB layout?

A: Yes. All listed substitute parts use the TO-236-3 (SOT-23-3) Surface Mount package, which maintains identical pinout and footprint compatibility with the CPH3205-M-TL-E. No PCB redesign is required for mechanical placement.

Q: What compliance certifications apply to the substitute parts?

A: Both NSS60201LT1G and CPH3216-TL-EX are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). These certifications match the original CPH3205-M-TL-E, ensuring equivalent environmental and handling compliance.

Q: Why is the CPH3205-M-TL-E marked as Obsolete?

A: The CPH3205-M-TL-E carries Obsolete product status, indicating that onsemi has discontinued active manufacturing and support. The manufacturer-recommended substitute NSS60201LT1G is an Active product with ongoing availability and technical support.

Q: How do I determine which substitute is appropriate for my circuit?

A: Evaluate your circuit requirements against the three critical parameters: maximum collector current (Ic), collector-emitter breakdown voltage (Vce), and transition frequency (fT). If your circuit requires 3 A at 50 V and 380 MHz operation, neither substitute fully meets all specifications. If current is limited to 2 A or less, the NSS60201LT1G is the recommended choice. If current is limited to 1 A or less, the CPH3216-TL-EX is suitable.
