DDA114YK-7-F Equivalent & Substitute Parts

Part Overview

The DDA114YK-7-F is a pre-biased dual PNP bipolar transistor manufactured by Diodes Incorporated, designed for surface mount applications in the SOT-26 package. This component integrates two PNP transistors with internal biasing resistors, providing a compact solution for switching and amplification circuits requiring 50V collector-emitter breakdown voltage and 100mA maximum collector current.

The DDA114YK-7-F is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications. Alternative models with equivalent electrical characteristics and compatible packaging are available from both Diodes Incorporated and Toshiba Semiconductor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DDA114YK-7-F is determined by equivalence in the following critical parameters:

Electrical Equivalence Criteria:

• Transistor configuration: 2 PNP - Pre-Biased (Dual)
• Maximum collector current: 100mA
• Collector-emitter breakdown voltage: 50V
• Internal base resistor (R1): 10kOhms
• Internal emitter-base resistor (R2): 47kOhms
• Saturation voltage: 300mV @ 250µA, 5mA
• Transition frequency: 200MHz or higher

Mechanical Compatibility:

• Surface mount technology
• Compatible package footprints for PCB assembly

Compliance Requirements:

• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts are grouped into two categories based on package type and power dissipation characteristics. The DDA114YU-7-F maintains identical electrical specifications with a different package form (SOT-363). The Toshiba RN2602 and RN2607 series provide electrical equivalence with variations in internal resistor values and transition frequency, accommodating design flexibility within the specified parameter ranges.

Engineering Selection Recommendations

DDA114YU-7-F (Diodes Incorporated)

The DDA114YU-7-F is the primary substitute for the obsolete DDA114YK-7-F. This part maintains identical electrical specifications including collector current, breakdown voltage, internal resistor values, and DC current gain. The component is in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. The package form differs (SOT-363 versus SOT-26), requiring PCB layout modification. This substitute is recommended for new designs and production continuity where package footprint changes are acceptable.

RN2607(TE85L,F) (Toshiba Semiconductor)

The RN2607(TE85L,F) provides electrical equivalence with the DDA114YK-7-F across all critical parameters including the 47kOhms emitter-base resistor configuration. This Toshiba component is in active production with RoHS compliance and unlimited moisture sensitivity. The transition frequency is 200MHz compared to 250MHz in the original part. The SC-74/SOT-457 package requires PCB layout modification. This substitute is suitable for applications where the lower transition frequency is acceptable and Toshiba component sourcing is preferred.

RN2602(TE85L,F) (Toshiba Semiconductor)

The RN2602(TE85L,F) offers electrical compatibility with a variation in the emitter-base resistor value (10kOhms versus 47kOhms). This configuration results in different biasing characteristics and a minimum DC current gain of 50 versus 68 in the original part. The component is in active production with RoHS compliance and unlimited moisture sensitivity. The transition frequency is 200MHz. This substitute is applicable only when the modified internal resistor network and lower current gain are compatible with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the DDA114YU-7-F directly replace the DDA114YK-7-F without circuit modification?

A: The DDA114YU-7-F provides identical electrical specifications and internal resistor values. However, the package changes from SOT-26 to SOT-363, requiring PCB footprint modification. No circuit redesign is necessary if the new package footprint is accommodated in the layout.

Q: What is the primary difference between the DDA114YU-7-F and the Toshiba RN2607(TE85L,F)?

A: Both parts maintain the 47kOhms emitter-base resistor configuration and equivalent saturation voltage. The DDA114YU-7-F operates at 250MHz transition frequency with 200mW maximum power, while the RN2607 operates at 200MHz with 300mW maximum power. Package types differ: SOT-363 versus SC-74/SOT-457.

Q: Why does the RN2602(TE85L,F) have a different emitter-base resistor value?

A: The RN2602 incorporates a 10kOhms emitter-base resistor instead of 47kOhms, resulting in different biasing characteristics and a minimum DC current gain of 50 versus 68. This configuration is suitable only for applications where these parameter variations are acceptable.

Q: Are all substitute parts RoHS compliant?

A: Yes. The DDA114YU-7-F is ROHS3 compliant. The RN2602 and RN2607 are RoHS compliant. All parts meet environmental compliance requirements for lead-free manufacturing.

Q: What is the moisture sensitivity level for these components?

A: All listed parts, including the original DDA114YK-7-F and all substitutes, have a moisture sensitivity level of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Can the RN2607(TE85L,F) be used in high-frequency applications requiring 250MHz operation?

A: The RN2607 operates at 200MHz transition frequency, which is lower than the original 250MHz specification. Use of this part in applications requiring 250MHz operation requires verification that the reduced transition frequency does not impact circuit performance.

Q: What package considerations apply when switching from DDA114YK-7-F to substitute parts?

A: The DDA114YK-7-F uses SOT-26 packaging. The DDA114YU-7-F uses SOT-363 (6-TSSOP/SC-88). The Toshiba parts use SC-74/SOT-457. Each package change requires corresponding PCB footprint modification and assembly process adjustment.
