DTA114TUBTL Equivalent & Substitute Parts Reference

Part Overview

DTA114TUBTL from Rohm Semiconductor is a pre-biased PNP bipolar junction transistor rated for 50V collector-emitter breakdown voltage, 100mA collector current, and 200mW maximum power dissipation, housed in a surface-mount UMT3 (SC-70, SOT-323) package. Its product status is “Not For New Designs.” Alternative models are necessary for ongoing production, design-in, and long-term support when the primary part is unavailable or not recommended for new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is strictly based on matching the following key parameters: transistor type (PNP - Pre-Biased), collector current rating (100 mA), collector-emitter breakdown voltage (50 V), base resistor value (10 kOhms), package type (SC-70, SOT-323), mounting type (Surface Mount), power dissipation (200 mW), RoHS compliance, and MSL. Only parts matching these criteria are included.

Parameter Comparison

Engineering Selection Recommendations

DTA114TUBTL has a product status of "Not For New Designs." Substitute parts such as DDTA114TUA-7-F (Diodes Incorporated) and PDTA114TU,115 (Nexperia USA Inc.) have product status "Active" and match RoHS3 compliance and MSL 1 (Unlimited). Selecting substitutes which maintain the same compliance and qualification parameters is appropriate within the provided criteria.

Frequently Asked Questions (FAQ)

Q: What factors determine whether a substitute PNP pre-biased SOT-323 transistor is suitable?
A: Only transistor type, collector current rating, collector-emitter breakdown voltage, base resistor value, package and mounting type, and power dissipation are considered. Substitute parts must match these parameters.

Q: Are there package differences among DTA114TUBTL and its substitutes?
A: All parts listed use a compatible surface-mount SC-70 (SOT-323) package. Supplier device package designations may differ (UMT3, SOT-323), but they refer to mechanically compatible form factors.

Q: Do RoHS and MSL status affect substitution?
A: Substitute parts listed maintain ROHS3 compliant status and MSL 1 (Unlimited), aligning with lead-free and moisture resistance standards required for automated manufacturing.

Q: Is the base resistor value critical for substitution?
A: Yes. Only parts with a 10 kOhm base resistor, matching the original DTA114TUBTL, are listed as substitutes.

Q: Are other brands or series allowed in this equivalence list?
A: Only manufacturer part numbers provided and whose parameters match the required specifications are included. No additional models or brands are shown.
