DRA5114T0L Equivalent & Substitute Parts

Part Overview

The DRA5114T0L is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Panasonic Electronic Components. This surface mount device is designed for general-purpose switching and amplification applications requiring a 50 V collector-emitter breakdown voltage rating and 100 mA maximum collector current. The device is packaged in the SMini3-F2-B surface mount configuration (SC-85 case).

The DRA5114T0L has been discontinued at DiGi Electronics, necessitating identification of functionally equivalent substitute components. Suitable alternatives must maintain electrical compatibility across critical parameters including voltage ratings, current specifications, base resistor values, and saturation characteristics while accommodating different surface mount package formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRA5114T0L is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor type: PNP - Pre-Biased configuration
• Maximum collector current: 100 mA
• Maximum collector-emitter breakdown voltage: 50 V
• Base resistor value: 10 kOhms
• Maximum collector cutoff current: 500 nA
• Moisture sensitivity level: 1 (Unlimited)

Mechanical Compatibility:

• Surface mount mounting type
• Compatible package footprints (SC-85, SC-70, SOT-323 formats are mechanically interchangeable in most applications)

Compliance Requirements:

• RoHS compliance status

The substitute parts DTA114TU3HZGT106 and DTA114TU3T106 (both manufactured by Rohm Semiconductor) satisfy all electrical equivalence criteria. Both devices are manufactured under the DTA114 base product number and maintain identical collector current, breakdown voltage, base resistor, and cutoff current specifications. Both are active products with enhanced power ratings (200 mW versus 150 mW) and transition frequency specifications (250 MHz), providing additional performance margin. Package format differences (UMT3 / SC-70, SOT-323 versus SMini3-F2-B / SC-85) require PCB layout verification but do not affect electrical functionality.

Parameter Comparison

Engineering Selection Recommendations

DTA114TU3HZGT106 (Rohm Semiconductor): This substitute part is qualified to AEC-Q101 automotive standards and carries ROHS3 compliance certification. The device is currently in active production with 2685 units in stock. The automotive qualification provides additional assurance of manufacturing consistency and reliability. The UMT3 package (SC-70, SOT-323) requires PCB layout modification from the original SC-85 footprint but maintains electrical equivalence across all specified parameters.

DTA114TU3T106 (Rohm Semiconductor): This substitute part is functionally identical to DTA114TU3HZGT106 with ROHS3 compliance and active product status. Inventory availability is higher at 3801 units in stock. This variant does not carry automotive qualification but meets all electrical and environmental specifications required for general-purpose applications. The UMT3 package format applies the same PCB layout considerations as the AEC-Q101 qualified variant.

Both Rohm devices provide enhanced power dissipation capability (200 mW versus 150 mW) and transition frequency specification (250 MHz), offering performance margin beyond the original DRA5114T0L specification. Selection between the two Rohm alternatives depends on automotive qualification requirements and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can DTA114TU3HZGT106 or DTA114TU3T106 be used as direct replacements for DRA5114T0L without circuit modification?

A: Electrical substitution is direct. Both Rohm devices maintain identical collector current (100 mA), breakdown voltage (50 V), base resistor (10 kOhms), and cutoff current (500 nA) specifications. However, package format differs (UMT3 / SC-70, SOT-323 versus SMini3-F2-B / SC-85), requiring PCB footprint modification and layout verification.

Q: What is the difference between DTA114TU3HZGT106 and DTA114TU3T106?

A: Both devices are electrically identical with matching electrical specifications. DTA114TU3HZGT106 carries AEC-Q101 automotive qualification; DTA114TU3T106 does not. Inventory levels differ (2685 units versus 3801 units). Selection depends on automotive qualification requirements for the application.

Q: Are the Rohm substitutes compatible with the original RoHS compliance requirement?

A: Yes. The DRA5114T0L is RoHS Compliant; both Rohm substitutes are ROHS3 Compliant, which represents an enhanced compliance standard. ROHS3 compliance satisfies all RoHS requirements.

Q: What is the significance of the 250 MHz transition frequency specification on the Rohm devices?

A: The DRA5114T0L does not specify transition frequency; the Rohm devices specify 250 MHz. This parameter indicates switching speed capability and represents additional performance specification not present in the original part. For applications not requiring high-frequency operation, this specification does not affect substitution validity.

Q: Do the Rohm substitutes have the same power dissipation rating as the original?

A: No. The DRA5114T0L is rated at 150 mW maximum power dissipation; both Rohm substitutes are rated at 200 mW. The higher rating provides additional thermal margin and does not restrict substitution in applications designed for the original 150 mW specification.

Q: Is moisture sensitivity level identical across all three devices?

A: Yes. All three devices (DRA5114T0L, DTA114TU3HZGT106, and DTA114TU3T106) carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: What PCB layout considerations apply when substituting the package format?

A: The original DRA5114T0L uses SC-85 package; Rohm substitutes use SC-70 or SOT-323 packages. These are different physical footprints requiring PCB redesign. Pad spacing, trace routing, and component placement must be verified against the specific package datasheet for the selected substitute.
