DDA114TU-7 Equivalent & Substitute Parts

Part Overview

The DDA114TU-7 is a pre-biased dual PNP bipolar junction transistor (BJT) manufactured by Diodes Incorporated in SOT-363 surface mount packaging. This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The DDA114TU-7 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats with 4300 units in current inventory stock.

Equivalent and substitute parts are identified based on matching electrical characteristics, mechanical compatibility, and regulatory compliance. Substitute components must maintain functional equivalence within the specified parameter tolerances for direct circuit board replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DDA114TU-7 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Transistor configuration: 2 PNP - Pre-Biased (Dual)
• Maximum collector current: 100mA
• Maximum collector-emitter breakdown voltage: 50V
• Base resistor value: 10kOhms
• Maximum power dissipation: 200mW or greater

Mechanical Compatibility Requirements:

• Surface mount mounting type
• Package compatibility: SOT-363, SC-88, SC-70-6, 6-TSSOP, or UMT6 (all equivalent 6-pin surface mount packages)

Regulatory Compliance Requirements:

• ROHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• Active product status

Substitute parts are grouped into two categories: direct equivalents (identical packaging format) and functional equivalents (alternative packaging with compatible pinout and electrical performance).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with ROHS3 compliance and MSL 1 rating, confirming regulatory equivalence to the DDA114TU-7. Selection among substitute options is based on the following criteria:

Direct Packaging Equivalence: DDA114TU-7-F is the direct equivalent, supplied in Tape & Reel (TR) format instead of Cut Tape (CT). This part maintains identical electrical specifications and SOT-363 packaging, suitable for automated assembly processes requiring reel-format components.

Electrical Performance Margin: MUN5111DW1T1G, PUMB11,115, and PUMB11,135 provide increased power dissipation ratings (250mW and 300mW respectively) compared to the 200mW specification of DDA114TU-7. These parts are suitable for applications requiring thermal margin or higher power handling capability.

Alternative Package Formats: RN2911,LF (US6 package), SMUN5115DW1T1G (SC-88/SOT-363), and UMB11NTN (UMT6 package) provide functional equivalence with alternative surface mount package configurations. These options accommodate design layouts requiring specific package footprints while maintaining electrical compatibility.

Inventory Availability: UMB11NTN (22,189 units), PUMB11,135 (8,777 units), and PUMB11,115 (12,578 units) demonstrate highest current stock levels, supporting supply chain continuity and lead-time reduction.

Frequently Asked Questions (FAQ)

Q: Can DDA114TU-7-F be used as a direct replacement for DDA114TU-7?

A: Yes. DDA114TU-7-F is electrically and mechanically identical to DDA114TU-7, with the only difference being the packaging format (Tape & Reel versus Cut Tape). Both components use SOT-363 packaging and maintain identical electrical specifications. The substitution is valid for both manual and automated assembly processes.

Q: What is the difference between SOT-363, SC-88, and 6-TSSOP packages?

A: SOT-363, SC-88, and 6-TSSOP are equivalent designations for the same 6-pin surface mount package with identical pinout and footprint dimensions. These terms are used interchangeably by different manufacturers. UMT6 is a functionally equivalent package with the same pinout but different physical dimensions; PCB layout verification is required before substitution.

Q: Are PUMB11,115 and PUMB11,135 interchangeable?

A: Yes. Both parts are manufactured by Nexperia USA Inc. with identical electrical specifications, 6-TSSOP packaging, and 300mW power rating. The difference in part number designation reflects manufacturing lot or date code variations. Both are suitable for direct substitution with DDA114TU-7.

Q: Can I use UMB11NTN if my PCB is designed for SOT-363 footprint?

A: No. UMB11NTN uses UMT6 packaging, which has different physical dimensions than SOT-363. Although the electrical specifications and pinout are compatible, the PCB footprint must be verified and potentially modified. Consult the manufacturer datasheets for precise dimensional specifications before layout changes.

Q: What is the significance of the power rating difference between DDA114TU-7 (200mW) and PUMB11,115 (300mW)?

A: The 300mW rating of PUMB11,115 indicates higher thermal capability and power dissipation margin. This part is suitable for applications operating at higher current levels or ambient temperatures. The DDA114TU-7 specification of 200mW is the minimum requirement; substitution with higher-rated parts does not create compatibility issues.

Q: Are all listed substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, confirming regulatory equivalence to DDA114TU-7 for use in restricted substance environments.

Q: What packaging format should I select for automated assembly?

A: Tape & Reel (TR) format is standard for automated pick-and-place assembly. DDA114TU-7-F, MUN5111DW1T1G, SMUN5115DW1T1G, PUMB11,115, PUMB11,135, and UMB11NTN are all supplied in Tape & Reel format. Cut Tape (CT) format is suitable for manual assembly or low-volume production.
