TPS2383BPM Equivalent & Substitute Parts

Part Overview

The TPS2383BPM is a Power Over Ethernet (PoE) Controller designed for 8-channel 802.3af applications in a 64-LQFP surface mount package. This component manages power delivery and protection in PoE systems operating within the 44V to 57V supply range. The TPS2383BPM is classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS2383BPM is determined by the following critical parameters:

Primary Compatibility Criteria:

• PoE Standard Compliance: 802.3af (PoE)
• Supply Voltage Range: 44V ~ 57V
• Maximum Power Output: 15.4 W
• Mounting Type: Surface Mount
• RoHS3 Compliance

Channel Configuration Consideration: The TPS2383BPM operates as an 8-channel controller. Substitute parts may differ in channel count while maintaining functional equivalence for systems where channel reduction is acceptable or where multiple controllers can be deployed in parallel configurations.

Package Compatibility: The 64-LQFP package footprint is the primary mechanical constraint. Substitutes in alternative 64-pin packages (such as 64-HTQFP) require PCB redesign and are classified as design-level substitutes rather than direct drop-in replacements.

Parameter Comparison

Engineering Selection Recommendations

TPS2383APM (Direct Functional Equivalent)

The TPS2383APM maintains identical electrical specifications and package footprint to the TPS2383BPM, providing direct substitution capability. Both devices feature 8-channel configuration, matching supply voltage and current parameters, and identical operating temperature range. The TPS2383APM is classified as "Not For New Designs," indicating limited long-term availability. This part is suitable for legacy system maintenance and repair applications where existing PCB designs must be preserved.

TPS2384PAP (Design-Level Substitute)

The TPS2384PAP is an Active product offering extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) and integrated internal switching functionality. The primary trade-off is reduced channel count (4 channels versus 8 channels) and different package designation (64-HTQFP versus 64-LQFP), requiring PCB redesign. The TPS2384PAP is suitable for new designs requiring enhanced thermal performance and integrated switching capabilities, provided system architecture accommodates 4-channel operation or parallel controller deployment.

Frequently Asked Questions (FAQ)

Q: Can TPS2383APM be used as a direct replacement for TPS2383BPM without PCB modification?

A: Yes. The TPS2383APM shares identical electrical specifications, pin configuration, and 64-LQFP package footprint with the TPS2383BPM. No PCB redesign is required for direct substitution.

Q: What is the primary limitation of using TPS2384PAP as a substitute?

A: The TPS2384PAP uses a 64-HTQFP package instead of 64-LQFP, requiring PCB redesign. Additionally, it provides 4 channels instead of 8, necessitating system architecture evaluation for compatibility.

Q: Are all three parts compliant with current environmental and regulatory standards?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Which substitute part is recommended for new product designs?

A: The TPS2384PAP is the only Active product among the three options. It is suitable for new designs requiring PoE controller functionality, provided the 4-channel configuration and extended temperature range align with system requirements.

Q: What is the supply current difference between TPS2383BPM and TPS2384PAP?

A: The TPS2383BPM draws 5mA supply current, while the TPS2384PAP draws 10mA. This difference should be evaluated in power budget calculations for systems with strict supply current constraints.
