RN1908(T5L,F,T) Equivalent & Substitute Parts
Part Overview
The RN1908(T5L,F,T) is an active pre-biased dual NPN bipolar transistor manufactured by Toshiba Semiconductor and Storage. This surface mount component integrates two NPN transistors with internal biasing resistors in a 6-TSSOP package, designed for applications requiring compact switching and amplification circuits. The device operates at 50V maximum collector-emitter breakdown voltage with 100mA maximum collector current and 200mW power dissipation. Finding equivalent and substitute parts is necessary to address supply chain continuity, inventory optimization, and design flexibility across manufacturing batches and procurement cycles.

Substitute Part Grouping Explanation
Substitution of the RN1908(T5L,F,T) is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Transistor configuration: 2 NPN - Pre-Biased (Dual)
- Maximum collector current: 100mA
- Maximum collector-emitter breakdown voltage: 50V
- Internal base resistor (R1): 22kOhms
- Internal emitter-base resistor (R2): 47kOhms
- Minimum DC current gain (hFE): 80
- Package type: 6-TSSOP, SC-88, SOT-363 (surface mount)
- Mounting type: Surface Mount
The PUMH16,115 manufactured by Nexperia USA Inc. satisfies all mandatory matching parameters. Both devices feature identical transistor configuration, current ratings, voltage ratings, internal resistor values, and minimum current gain specifications. Both are housed in compatible 6-TSSOP surface mount packages and maintain RoHS compliance. The substitute part is qualified to AEC-Q100 automotive standards, providing additional qualification coverage beyond the base requirement.

Engineering Selection Recommendations
Primary Selection: RN1908(T5L,F,T)
The RN1908(T5L,F,T) remains the primary component choice for applications where Toshiba supply chain continuity is established and inventory is available. The device carries active product status and RoHS compliance certification. Current inventory of 3919 pieces supports immediate procurement requirements.
Substitute Selection: PUMH16,115
The PUMH16,115 serves as a direct functional substitute when RN1908(T5L,F,T) availability is constrained. This Nexperia device maintains all critical electrical parameters and package compatibility. The substitute carries active product status, ROHS3 compliance, and AEC-Q100 automotive qualification. The higher maximum power rating (300mW versus 200mW) and improved saturation voltage characteristics (150mV versus 300mV) provide enhanced performance margins. Current inventory of 5809 pieces ensures supply availability. Both devices share identical moisture sensitivity classification (MSL 1) and ECCN/HTSUS coding, simplifying regulatory and logistics documentation.
Frequently Asked Questions (FAQ)
Q: Can PUMH16,115 be used as a direct replacement for RN1908(T5L,F,T) in existing designs?
A: Yes. Both devices feature identical transistor configuration (2 NPN pre-biased), matching maximum collector current (100mA), collector-emitter breakdown voltage (50V), internal resistor values (R1=22kOhms, R2=47kOhms), and minimum DC current gain (80). Package compatibility is confirmed across 6-TSSOP, SC-88, and SOT-363 designations. Pin-to-pin functionality is equivalent for all switching and amplification applications.
Q: What are the differences between these two parts?
A: The primary differences are manufacturer origin and performance enhancements. PUMH16,115 provides higher maximum power dissipation (300mW versus 200mW), lower saturation voltage (150mV versus 300mV), and AEC-Q100 automotive qualification. Collector cutoff current differs (1µA versus 100nA), with the substitute showing slightly higher leakage. These differences do not affect functional substitution in standard applications.
Q: Are both parts available in the same packaging options?
A: Yes. Both RN1908(T5L,F,T) and PUMH16,115 are supplied in 6-TSSOP surface mount packages. The RN1908 is available in Cut Tape (CT) packaging, while PUMH16,115 is supplied in Tape & Reel (TR) format. Both formats are compatible with standard surface mount assembly processes.
Q: Do these parts have the same moisture sensitivity requirements?
A: Yes. Both devices carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Storage and handling procedures are identical for both components.
Q: Which part should be selected for automotive applications?
A: PUMH16,115 is qualified to AEC-Q100 automotive standards, making it the specified choice for automotive designs. RN1908(T5L,F,T) carries no automotive qualification designation. For non-automotive applications, either part is acceptable based on availability and supply chain preference.
Q: Are there any regulatory or compliance differences?
A: Both parts are RoHS compliant (RN1908 carries RoHS standard compliance; PUMH16,115 carries ROHS3 compliance). PUMH16,115 includes REACH Unaffected status. Both share identical ECCN (EAR99) and HTSUS (8541.21.0095) classifications, simplifying export and import documentation.
