TPS2383BPMRG4 Equivalent & Substitute Parts

Part Overview

The TPS2383BPMRG4 is a Power Over Ethernet (PoE) Controller designed for 8-channel 802.3af applications in a 64-LQFP surface mount package. This component is classified as a PSE (Power Sourcing Equipment) controller and is currently discontinued at DiGi Electronics. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for system redesign, production continuity, and long-term component sourcing strategies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2383BPMRG4 is determined by strict alignment of the following critical parameters:

• Channel Configuration: 8-channel PSE controller architecture
• PoE Standard Compliance: 802.3af (PoE) standard
• Maximum Power Output: 15.4 W per channel
• Supply Voltage Range: 44V ~ 57V input
• Package Format: 64-LQFP (10x10) surface mount
• Thermal Operating Range: -40°C ~ 85°C
• Regulatory Compliance: ROHS3, REACH Unaffected, EAR99

The substitute part TPS2383BPMR meets all these critical parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TPS2383BPMR is the direct substitute for the TPS2383BPMRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package geometry, and regulatory compliance certifications. The primary distinction is product lifecycle status: the main part is discontinued at DiGi Electronics, while the substitute is classified as obsolete. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs or production transitions.

Selection of the TPS2383BPMR should be based on current inventory availability and supply chain lead times, as both parts represent the same functional platform within the TPS2383 base product family.

Frequently Asked Questions (FAQ)

Q: Can the TPS2383BPMR be used as a direct replacement for the TPS2383BPMRG4?

A: Yes. Both parts are functionally identical across all critical parameters: 8-channel PSE controller, 802.3af PoE standard, 15.4 W maximum power, 44V–57V supply voltage, 64-LQFP package, and identical thermal and compliance specifications.

Q: What is the difference between the TPS2383BPMRG4 and TPS2383BPMR?

A: The parts are electrically and mechanically identical. The difference is product lifecycle status: TPS2383BPMRG4 is discontinued at DiGi Electronics, while TPS2383BPMR is obsolete. Both are based on the TPS2383 base product number.

Q: Are there any package or pinout differences?

A: No. Both parts use the 64-LQFP (10x10) surface mount package with identical pinout and mechanical dimensions.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with the same HTSUS code (8542.39.0001).

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

A: Both parts have MSL 3 with a 168-hour floor life rating, requiring standard moisture control during storage and handling.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical package, pinout, and electrical specifications allow direct PCB assembly interchange without design modifications.
