PEMH16,115 Equivalent & Substitute Parts

Part Overview

The PEMH16,115 is a pre-biased dual NPN bipolar junction transistor (BJT) manufactured by Nexperia USA Inc. in SOT-666 surface mount packaging. This component integrates two NPN transistors with internal biasing resistors, designed for 50V operation with a maximum collector current of 100mA and 300mW power dissipation. The part is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Identifying equivalent and substitute parts is necessary for legacy system support, design continuity, and procurement flexibility when the original part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PEMH16,115 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Transistor configuration: 2 NPN - Pre-Biased (Dual)
• Voltage rating: 50V Collector-Emitter breakdown minimum
• Current rating: 100mA maximum collector current
• Internal biasing resistors: R1 = 22kOhms, R2 = 47kOhms
• DC current gain: hFE minimum of 80
• Mounting type: Surface Mount
• RoHS3 compliance and MSL 1 rating

Package Compatibility: The PEMH16,115 is supplied in SOT-666 packaging. Substitute parts may be available in SOT-563 or SOT-666 packages, both of which are acceptable for the dual pre-biased NPN configuration. Package selection depends on PCB layout constraints and design requirements.

Product Status Consideration: The PEMH16,115 is marked "Not For New Designs." Substitute parts with "Active" product status provide continued manufacturer support and availability assurance.

Engineering Selection Recommendations

NSBC124XDXV6T1G (onsemi) - Primary Substitute

The NSBC124XDXV6T1G is the preferred direct substitute for the PEMH16,115. This part maintains all critical electrical parameters including 50V breakdown voltage, 100mA collector current, and identical internal biasing resistor values (22kOhms and 47kOhms). The onsemi part offers enhanced power dissipation capability (500mW versus 300mW), providing additional thermal margin in applications. The part carries "Active" product status, ensuring ongoing manufacturer support and supply chain availability. ROHS3 compliance and MSL 1 rating match the original specification. The SOT-563 package is a compact alternative to SOT-666, suitable for space-constrained designs.

RN1908FE(TE85L,F) (Toshiba Semiconductor and Storage) - Secondary Substitute

The RN1908FE(TE85L,F) provides functional equivalence with all core electrical parameters matching the PEMH16,115. This Toshiba part maintains the 50V voltage rating, 100mA current capability, and identical biasing resistor configuration. The part includes specified transition frequency of 250MHz, enabling use in higher-frequency applications. The RN1908FE operates at reduced power dissipation (100mW), making it suitable for thermally constrained environments. Active product status and RoHS compliance ensure long-term availability. The ES6 package differs from SOT-666 and SOT-563, requiring PCB layout verification before implementation.

Compliance and Certification Alignment

Both substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols. All three parts carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory equivalence for procurement and logistics purposes.

Frequently Asked Questions (FAQ)

Q: Can the NSBC124XDXV6T1G replace the PEMH16,115 in existing designs?

A: Yes. The NSBC124XDXV6T1G maintains electrical equivalence across all critical parameters: 50V breakdown voltage, 100mA maximum collector current, 22kOhms base resistor, and 47kOhms emitter-base resistor. The primary difference is packaging (SOT-563 versus SOT-666). PCB layout compatibility must be verified before implementation. The higher power rating (500mW) provides additional thermal margin.

Q: What is the difference between SOT-666 and SOT-563 packaging?

A: SOT-666 and SOT-563 are both surface mount packages for dual pre-biased NPN transistors. SOT-563 is a more compact package footprint. Both packages are electrically equivalent for this application. PCB design files and assembly equipment compatibility must be confirmed before switching packages.

Q: Is the RN1908FE(TE85L,F) suitable for high-frequency applications?

A: The RN1908FE(TE85L,F) specifies a transition frequency of 250MHz, enabling operation in higher-frequency circuits compared to the PEMH16,115 and NSBC124XDXV6T1G, which do not specify transition frequency. However, the RN1908FE operates at reduced maximum power dissipation (100mW), which may limit use in high-current applications.

Q: Are all three parts RoHS compliant?

A: Yes. The PEMH16,115 is ROHS3 compliant. The NSBC124XDXV6T1G is ROHS3 compliant. The RN1908FE(TE85L,F) is RoHS compliant. All three parts meet environmental and regulatory requirements for standard manufacturing and deployment.

Q: What is the significance of "Not For New Designs" status on the PEMH16,115?

A: "Not For New Designs" indicates that Nexperia has discontinued active development and marketing of this part. The part remains available from existing inventory but will not receive design updates or long-term support. For new designs or legacy system replacements, the NSBC124XDXV6T1G (Active status) or RN1908FE(TE85L,F) (Active status) are recommended to ensure sustained availability and manufacturer support.

Q: Do the substitute parts have identical DC current gain specifications?

A: All three parts specify a minimum DC current gain (hFE) of 80. However, the test conditions differ: PEMH16,115 at 5mA/5V, NSBC124XDXV6T1G at 5mA/10V, and RN1908FE(TE85L,F) at 10mA/5V. These variations reflect different manufacturer characterization methodologies but do not affect functional equivalence in typical applications.

Q: What is the moisture sensitivity level (MSL) rating, and why does it matter?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These components can be stored and handled under standard industrial conditions without special desiccant packaging or shelf-life limitations. This simplifies procurement, inventory management, and assembly processes.

Q: Can I use the RN1908FE in place of the NSBC124XDXV6T1G?

A: Electrical substitution is possible due to matching core parameters. However, the RN1908FE operates at significantly lower maximum power dissipation (100mW versus 500mW). Applications requiring sustained power dissipation above 100mW must use the NSBC124XDXV6T1G or PEMH16,115. Additionally, the ES6 package differs from SOT-563, requiring PCB layout verification.
