IRS2573DSPBF Equivalent & Substitute Parts
Part Overview
The IRS2573DSPBF is an HID lamp controller manufactured by Infineon Technologies, designed to operate at frequencies between 160Hz and 240Hz. This integrated circuit manages high-intensity discharge lamp ignition and operation within the specified frequency range. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation
Substitution of the IRS2573DSPBF is constrained by the following critical parameters:
Functional Requirements:
- HID lamp control capability within 160Hz ~ 240Hz frequency band
- Supply voltage compatibility: 9.5V ~ 16.6V input range
- Surface mount packaging suitable for existing PCB layouts
Electrical Compatibility:
- Supply current specifications must accommodate system power budgets
- Operating temperature range must support -40°C ~ 125°C environments
- Regulatory compliance (REACH Unaffected, EAR99 classification)
The IRS2453DSTRPBF is identified as a manufacturer-recommended substitute. However, this device functions as a full-bridge gate driver rather than a dedicated HID lamp controller. Substitution requires verification that gate driver functionality can fulfill the lamp control requirements within the specified frequency and voltage parameters of the original application.

Engineering Selection Recommendations
Selection between the IRS2573DSPBF and IRS2453DSTRPBF must account for the following factors:
Product Status Consideration: The IRS2573DSPBF is obsolete. The IRS2453DSTRPBF maintains active product status with Infineon Technologies, ensuring ongoing availability and manufacturing support.
Voltage Compatibility: The IRS2453DSTRPBF supply voltage range (10V ~ 15.6V) overlaps substantially with the IRS2573DSPBF range (9.5V ~ 16.6V). Applications operating below 10V or above 15.6V require alternative solutions.
Temperature Range: The IRS2573DSPBF supports operation to -40°C; the IRS2453DSTRPBF minimum is -25°C. Systems requiring -40°C operation cannot use the substitute without thermal management modifications.
Package Footprint: The IRS2453DSTRPBF uses a smaller 14-SOIC package versus the 28-SOIC of the original. PCB layout redesign is required for physical integration.
Regulatory Compliance: Both devices maintain REACH Unaffected status and EAR99 classification, satisfying export and environmental compliance requirements.
Frequently Asked Questions (FAQ)
Q: Can the IRS2453DSTRPBF directly replace the IRS2573DSPBF on existing PCBs?
A: No. The IRS2453DSTRPBF uses a 14-SOIC package compared to the 28-SOIC of the original. Pin count and footprint differ, requiring PCB redesign and re-layout.
Q: What is the functional difference between these devices?
A: The IRS2573DSPBF is a dedicated HID lamp controller. The IRS2453DSTRPBF is a full-bridge gate driver. Functional equivalence depends on whether gate driver operation can satisfy the lamp control requirements of the original application.
Q: Are there voltage compatibility issues?
A: The IRS2453DSTRPBF operates from 10V ~ 15.6V, while the IRS2573DSPBF operates from 9.5V ~ 16.6V. Applications with supply voltages below 10V or above 15.6V cannot use the substitute.
Q: Does the temperature range differ?
A: Yes. The IRS2573DSPBF operates to -40°C minimum; the IRS2453DSTRPBF operates to -25°C minimum. Systems requiring -40°C operation require alternative solutions or thermal management.
Q: What packaging formats are available?
A: The IRS2573DSPBF is supplied in standard packaging. The IRS2453DSTRPBF is available in Tape & Reel (TR) format, suitable for automated assembly processes.
Q: Are both devices compliant with environmental regulations?
A: Yes. Both devices maintain REACH Unaffected status and EAR99 export classification.
