DTC114YUBTL Equivalent & Substitute Parts Reference

Part Overview

DTC114YUBTL is a pre-biased NPN bipolar junction transistor (BJT) manufactured by Rohm Semiconductor, featuring a collector-emitter breakdown voltage of 50 V, collector current up to 70 mA, and integrated resistors for biasing. It is supplied in a compact surface-mount UMT3F/SC-85 package, designed for applications requiring a pre-biased configuration with optimized switching performance.

This part is classified as "Not For New Designs," indicating it is not recommended for use in future product designs. Engineers sourcing this BJT must evaluate alternative parts with matching parameters for design continuity, form-fit-function compatibility, and ongoing supply.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for DTC114YUBTL are selected strictly according to matching core electrical and mechanical parameters relevant to the Transistors, Bipolar (BJT) category. The key parameters considered for equivalence include:

• Transistor Type (NPN - Pre-Biased)
• Voltage - Collector Emitter Breakdown (Max)
• Current - Collector (Ic) (Max)
• Base and emitter resistor values (R1, R2)
• DC Current Gain (hFE) (Min) @ Ic, Vce
• Vce Saturation (Max)
• Frequency - Transition
• Power - Max
• Surface-mount compatibility and package type
• RoHS and REACH compliance
• Moisture Sensitivity Level (MSL)

Parts meeting these criteria are considered permissible direct substitutes within their defined category and application. Only product information supplied has been used for grouping.

Parameter Comparison

Engineering Selection Recommendations

DTC114YUBTL is listed as "Not For New Designs" and is ROHS3 compliant, REACH unaffected, with MSL 1 (Unlimited). Substitute PDTC114YU,115 is listed as "Active" with identical RoHS and ECCN compliance status, and meets all provided environmental, packaging, and mechanical criteria. Select PDTC114YU,115 as a direct substitute strictly due to the main part’s limited design recommendation and ongoing compliance status.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters are mandatory for substitution in this product category?
A1: Transistor type, collector-emitter breakdown voltage, collector current, base and emitter resistor values, DC current gain, saturation voltage, cutoff current, frequency, and power rating are required for direct substitution in the bipolar BJT category.

Q2: Does changing package type affect substitution?
A2: Substitution is allowed only when the mounting type remains surface mount, and the package is compatible with the application’s footprint. Provided information specifies SC-85 (UMT3F) and SC-70/SOT-323 options.

Q3: Is RoHS and REACH compliance maintained in the substitute part?
A3: Both DTC114YUBTL and PDTC114YU,115 are stated as ROHS3 compliant and REACH unaffected.

Q4: Are the integrated resistors (R1, R2) matched in both parts?
A4: Yes, both parts have R1 = 10 kOhms and R2 = 47 kOhms.

Q5: Can the substitute part be used in new designs?
A5: PDTC114YU,115 is marked as "Active," and is suitable for ongoing and future designs according to the provided status.

Q6: How are differences in maximum collector current addressed?
A6: The substitute part PDTC114YU,115 offers a higher maximum collector current; substitution is permitted as the main parameters are met.
