ZY1115G-T3 Equivalent & Substitute Parts

Part Overview

The ZY1115G-T3 is a non-isolated Point-of-Load (PoL) module digital DC-DC converter manufactured by Bel Power Solutions. This single-output converter operates with an input voltage range of 3V to 14V and delivers adjustable output voltage from 0.5V to 5.5V at a maximum current of 15A. The device is designed for commercial Information Technology Equipment (ITE) applications and operates across an extended temperature range of -40°C to 85°C.

The ZY1115G-T3 is classified as an obsolete product. Locating equivalent or substitute components becomes necessary when the original part is no longer available through standard distribution channels or when design requirements necessitate components with active product status and ongoing manufacturer support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZY1115G-T3 is evaluated based on the following critical parameters that define functional compatibility:

Input Voltage Compatibility: The substitute part must accept the same input voltage range or a subset thereof. The ZY1115G-T3 accepts 3V to 14V input.

Output Voltage Range: The substitute must provide the required output voltage adjustment range. The ZY1115G-T3 delivers 0.5V to 5.5V.

Output Current Capacity: The substitute must deliver the same maximum output current of 15A.

Thermal Operating Range: The substitute must maintain operation across -40°C to 85°C.

Form Factor and Mounting: The substitute must be compatible with surface mount applications and module-based packaging.

Regulatory Compliance: The substitute must maintain ROHS3 compliance and equivalent moisture sensitivity ratings.

The DP7115G-R100 qualifies as a substitute part based on these criteria, with the following considerations: the input voltage minimum is raised from 3V to 8V, and the output voltage minimum is raised from 0.5V to 0.7V. These differences represent a narrower operating envelope within the original specification range.

Parameter Comparison

Engineering Selection Recommendations

The DP7115G-R100 is the designated substitute for the obsolete ZY1115G-T3. Both components are manufactured by Bel Power Solutions and share identical output current capacity (15A), thermal operating range (-40°C to 85°C), and regulatory compliance status (ROHS3 Compliant, MSL 3).

The primary distinction between these parts is product status: the ZY1115G-T3 is obsolete, while the DP7115G-R100 maintains active product status with ongoing manufacturer support and availability. The DP7115G-R100 is available in Cut Tape and Digi-Reel packaging formats, supporting production and procurement workflows.

The DP7115G-R100 operates with a narrower input voltage range (8V to 14V versus 3V to 14V) and a higher minimum output voltage (0.7V versus 0.5V). These parameter differences must be evaluated against specific application requirements. If the design requires input voltages below 8V or output voltages below 0.7V, the DP7115G-R100 is not suitable for direct substitution.

For applications operating within the DP7115G-R100 parameter envelope, this substitute provides equivalent functionality with the advantage of active product status and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the DP7115G-R100 directly replace the ZY1115G-T3 in all applications?

A: Direct substitution is valid only when the application operates within the DP7115G-R100 parameter range. The substitute requires minimum input voltage of 8V (versus 3V for the original) and minimum output voltage of 0.7V (versus 0.5V for the original). Applications requiring lower input or output voltages require alternative solutions.

Q: What is the significance of the ZY1115G-T3 being classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support for this component. New inventory may be limited or unavailable through standard distribution. The DP7115G-R100 maintains active status with ongoing availability and manufacturer technical support.

Q: Are the physical dimensions compatible between these two parts?

A: The parts have different physical dimensions. The ZY1115G-T3 measures 1.26" L x 0.39" W x 0.55" H, while the DP7115G-R100 measures 1.26" L x 0.55" W x 0.31" H. Length is identical, but width and height differ. PCB layout and mechanical clearances must be verified before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the ZY1115G-T3 and DP7115G-R100 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8504.40.9580. Both maintain Moisture Sensitivity Level 3 (168 Hours).

Q: What packaging options are available for the DP7115G-R100?

A: The DP7115G-R100 is supplied in Cut Tape (CT) and Digi-Reel packaging formats, supporting both manual assembly and automated production environments.

Q: How do the output current capabilities compare?

A: Both parts deliver identical maximum output current of 15A, ensuring equivalent power delivery capacity in applications where this parameter is critical.
