• Resistor - Base (R1): 10 kΩ
• Resistor - Emitter Base (R2): 47 kΩ
• Mounting Type: Surface Mount
• Package compatibility: SC-101/SOT-883 or equivalent surface mount packages

Secondary Compatibility Factors:

• Current - Collector (Ic) (Max): 80 mA or greater
• Power - Max: 100 mW or greater
• DC Current Gain (hFE): Minimum 80 @ specified conditions
• RoHS and regulatory compliance status

Substitutes identified include the RN1107,LF(CT), PDTC114TM,315, and PDTC114YM,315. Each maintains the core pre-biased NPN architecture with matching resistor networks and voltage ratings. Variations in maximum collector current, power dissipation, and saturation voltage are noted where they exceed the original specification, indicating enhanced or equivalent performance capability.

Engineering Selection Recommendations

RN1107,LF(CT) - Toshiba Semiconductor and Storage

This substitute maintains identical base and emitter-base resistor values (10 kΩ and 47 kΩ) and collector-emitter breakdown voltage (50 V). The maximum collector current is increased to 100 mA, providing enhanced current handling capability. The part is ROHS3 Compliant with MSL 1 rating. Package configuration differs (SC-75/SOT-416 versus SC-101/SOT-883), requiring mechanical verification for PCB layout compatibility. Transition frequency specification of 250 MHz is provided for this variant.

PDTC114TM,315 - Philips

This pre-biased NPN transistor maintains the 10 kΩ and 47 kΩ resistor network and 50 V voltage rating. Limited detailed electrical specifications are provided in the available data. The part is Active status with REACH Unaffected designation. Bulk packaging is specified, differing from the cut tape and tape & reel options of other substitutes.

PDTC114YM,315 - Nexperia USA Inc.

This substitute provides identical package configuration (SC-101/SOT-883) to the main part, ensuring direct mechanical compatibility. The 50 V voltage rating and 10 kΩ/47 kΩ resistor network are maintained. Maximum collector current is 100 mA with enhanced power dissipation capability (250 mW versus 100 mW). DC current gain is specified at 100 @ 5mA, 5V. Vce saturation is reduced to 100 mV, indicating improved switching performance. ROHS3 Compliant with MSL 1 rating and REACH Unaffected status.

All identified substitutes maintain Active product status and comply with RoHS and moisture sensitivity requirements. Selection between substitutes depends on specific package requirements, current handling needs, and switching performance specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the RN1107,LF(CT) directly replace the RN1107ACT(TPL3) on the PCB?

A: The RN1107,LF(CT) uses package SC-75/SOT-416, while the RN1107ACT(TPL3) uses SC-101/SOT-883. These packages have different pin configurations and footprints. Direct PCB replacement is not possible without layout modification. Verify footprint compatibility before substitution.

Q: What are the key electrical differences between the RN1107ACT(TPL3) and PDTC114YM,315?

A: Both parts share the same 50 V voltage rating, 10 kΩ base resistor, and 47 kΩ emitter-base resistor. The PDTC114YM,315 offers higher maximum collector current (100 mA versus 80 mA), greater power dissipation (250 mW versus 100 mW), lower saturation voltage (100 mV versus 150 mV), and higher DC current gain (100 versus 80). The PDTC114YM,315 uses the same SC-101/SOT-883 package, enabling direct mechanical compatibility.

Q: Are all substitutes RoHS compliant?

A: The RN1107ACT(TPL3) is RoHS Compliant. The RN1107,LF(CT) and PDTC114YM,315 are ROHS3 Compliant. The PDTC114TM,315 does not specify RoHS status in the provided data. Verify RoHS compliance requirements for your application before final selection.

Q: What is the significance of the pre-biased configuration in these transistors?

A: The pre-biased configuration integrates base and emitter-base resistors directly into the transistor package. The 10 kΩ base resistor and 47 kΩ emitter-base resistor network are internal to all identified substitutes. This configuration simplifies circuit design by eliminating the need for external biasing resistors while maintaining consistent bias conditions across all qualified parts.

Q: Can the PDTC114TM,315 be used as a substitute if detailed specifications are not fully provided?

A: The PDTC114TM,315 is listed as a pre-biased NPN transistor with Active product status. However, critical electrical parameters such as maximum collector current, voltage rating, and resistor values are not specified in the available data. Substitution decisions require complete electrical specification verification from the manufacturer datasheet before implementation.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) packaging provides individual components cut from a continuous tape, suitable for smaller volume orders and manual assembly. Tape & Reel (TR) packaging maintains components on a continuous reel for automated pick-and-place assembly equipment. Both packaging types contain the same component; the difference is in supply format and handling method. Bulk packaging (as specified for PDTC114TM,315) provides loose components in larger quantities.

Q: Is the PDTC114YM,315 a direct replacement for the RN1107ACT(TPL3)?

A: The PDTC114YM,315 maintains identical package configuration (SC-101/SOT-883), voltage rating (50 V), and resistor network (10 kΩ/47 kΩ). Electrical performance is enhanced with higher current capacity (100 mA versus 80 mA) and improved saturation characteristics (100 mV versus 150 mV). Both parts are ROHS3 Compliant with MSL 1 rating. Direct PCB replacement is mechanically feasible; circuit performance will be equivalent or improved.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with this rating have unlimited shelf life and do not require special moisture control during storage or handling. All identified substitutes carry MSL 1 rating, ensuring consistent moisture management requirements across the product family.
