PMP4201V,115 Equivalent & Substitute Parts

Part Overview

The PMP4201V,115 is a dual NPN matched pair bipolar junction transistor (BJT) array manufactured by Nexperia USA Inc. in SOT-666 surface mount packaging. This component is designed for applications requiring matched transistor pairs with 45V collector-emitter breakdown voltage and 100mA maximum collector current. The part is classified as "Not For New Designs," indicating that Nexperia has discontinued active development and marketing of this product line. Identification of equivalent and substitute parts is necessary for design continuity, inventory management, and long-term product support in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PMP4201V,115 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor configuration: Dual NPN matched pair topology
• Maximum collector current: 100mA minimum requirement
• Collector-emitter breakdown voltage: 45V minimum requirement
• Saturation voltage characteristics: 400mV maximum at specified bias conditions
• Transition frequency: 250MHz minimum for high-frequency applications
• Power dissipation capability: 300mW minimum

Mechanical Compatibility Criteria:

• Surface mount packaging format
• SOT-666 or SOT-563 package compatibility
• Identical pin configuration and footprint alignment

Compliance and Certification:

• RoHS3 compliance mandatory
• Moisture sensitivity level MSL 1 (unlimited shelf life)
• REACH unaffected status

The EMX2DXV6T5G manufactured by onsemi meets these substitution criteria with the following considerations: it provides higher collector-emitter breakdown voltage (50V), increased power dissipation (500mW), and is available in SOT-563 packaging, which is mechanically compatible with SOT-666 footprints in most applications. However, the EMX2DXV6T5G is classified as obsolete, requiring evaluation of long-term availability.

Parameter Comparison

Engineering Selection Recommendations

PMP4201V,115 (Main Part): The PMP4201V,115 remains suitable for existing production runs and field replacements where inventory is available. The part maintains RoHS3 compliance and unlimited moisture sensitivity rating, supporting long-term storage without degradation. The "Not For New Designs" status indicates that Nexperia has transitioned this product to mature lifecycle management, but the part continues to meet all specified electrical and mechanical requirements for applications within its rated parameters.

EMX2DXV6T5G (Substitute): The EMX2DXV6T5G provides electrical and mechanical substitution capability with the following considerations:

• Voltage Rating: The 50V collector-emitter breakdown voltage exceeds the 45V requirement, providing additional design margin.
• Power Dissipation: The 500mW maximum power rating provides 67% additional headroom compared to the 300mW PMP4201V,115, supporting higher current or thermal stress applications.
• Transition Frequency: The 180MHz transition frequency is lower than the 250MHz specification of the PMP4201V,115. Applications requiring frequencies above 180MHz must verify performance through circuit simulation or prototype testing.
• DC Current Gain: The minimum hFE of 120 is lower than the PMP4201V,115 specification of 200, requiring bias network recalculation for constant-current or gain-dependent circuits.
• Collector Cutoff Current: The 500nA ICBO specification is significantly higher than the 15nA PMP4201V,115, affecting leakage current performance in precision analog applications.
• Product Status: The obsolete classification indicates limited future availability. Procurement planning must account for potential supply discontinuation.
• Compliance: RoHS3 compliance and MSL 1 rating match the main part requirements.

Substitution Feasibility: The EMX2DXV6T5G is electrically and mechanically compatible for applications where the lower transition frequency, reduced current gain, and higher leakage current do not compromise circuit performance. SOT-563 and SOT-666 packages are mechanically interchangeable in most PCB layouts. Both parts meet environmental and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the EMX2DXV6T5G directly replace the PMP4201V,115 without circuit modification?

A: Direct replacement is possible only if the application operates within the EMX2DXV6T5G electrical specifications. The lower transition frequency (180MHz vs. 250MHz) and reduced DC current gain (120 vs. 200) may require bias network adjustment. Applications sensitive to leakage current (15nA vs. 500nA ICBO) require circuit evaluation.

Q: Are SOT-563 and SOT-666 packages mechanically compatible?

A: Both packages are surface mount formats with identical pin configurations and footprint compatibility. PCB layouts designed for SOT-666 accept SOT-563 components without modification.

Q: What is the significance of the "Not For New Designs" and "Obsolete" product status classifications?

A: "Not For New Designs" indicates that Nexperia has discontinued active marketing and development of the PMP4201V,115 but continues to support existing applications. "Obsolete" indicates that onsemi has completely discontinued the EMX2DXV6T5G with no further production planned. Both statuses require long-term supply chain planning and inventory management.

Q: How does the higher collector-emitter breakdown voltage (50V vs. 45V) of the EMX2DXV6T5G affect circuit design?

A: The higher voltage rating provides additional design margin and protection against transient overvoltage conditions. No circuit modification is required; the part operates safely within the 45V design specification.

Q: What applications are affected by the transition frequency difference (250MHz vs. 180MHz)?

A: Applications operating above 180MHz, including RF amplifiers, high-speed switching circuits, and precision timing applications, require verification that the EMX2DXV6T5G meets performance requirements. Lower-frequency applications (below 180MHz) are unaffected.

Q: Does the higher leakage current (500nA vs. 15nA) of the EMX2DXV6T5G impact precision analog circuits?

A: Precision analog applications, including logarithmic amplifiers, transimpedance amplifiers, and low-level signal conditioning circuits, may experience performance degradation due to increased leakage current. Circuit simulation or prototype evaluation is necessary for these applications.

Q: Are both parts RoHS3 compliant and suitable for regulated industries?

A: Yes, both the PMP4201V,115 and EMX2DXV6T5G are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for most industrial and commercial applications.

Q: What is the recommended approach for long-term supply chain management?

A: Given the "Not For New Designs" status of the PMP4201V,115 and the "Obsolete" status of the EMX2DXV6T5G, procurement planning should identify alternative dual NPN matched pair transistor arrays from active product lines. Current inventory levels (8236 pcs for PMP4201V,115 and 1116 pcs for EMX2DXV6T5G) support near-term requirements but do not guarantee long-term availability.
