TPS2384PAPG4 Equivalent & Substitute Parts

Part Overview

The TPS2384PAPG4 is a Power Over Ethernet (PoE) Controller for 4-channel 802.3af applications, manufactured by Texas Instruments in a 64-HTQFP (10x10) surface mount package. This component is classified as a PSE (Power Sourcing Equipment) controller and is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2384PAPG4 is determined by strict equivalence across the following critical parameters:

• Functional Type: PSE Controller for 802.3af PoE applications
• Channel Configuration: 4-channel architecture
• Power Delivery Capability: 15.4 W maximum per channel
• Internal Switching: Integrated switch functionality required
• Package Specification: 64-PowerTQFP (10x10) surface mount
• Electrical Specifications: 44V–57V supply voltage, 10mA supply current
• Temperature Range: -40°C to 125°C operating window
• Compliance: ROHS3 and REACH requirements

The TPS2384PAP meets all these criteria and is the manufacturer-recommended substitute, differing only in packaging format (Tray vs. standard packaging) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The TPS2384PAP is the direct functional equivalent and manufacturer-recommended substitute for the TPS2384PAPG4. Both components share identical electrical specifications, package geometry, and compliance certifications (ROHS3, REACH Unaffected). The primary distinction is product status: TPS2384PAP is currently in active production, whereas TPS2384PAPG4 is discontinued.

For new designs or ongoing procurement, TPS2384PAP is the appropriate selection. The packaging format difference (Tray) does not affect electrical or mechanical compatibility and is a supply chain consideration only. Both parts maintain equivalent MSL ratings and temperature operating ranges suitable for industrial and commercial PoE applications.

Frequently Asked Questions (FAQ)

Q: Can TPS2384PAP directly replace TPS2384PAPG4 in existing designs?

A: Yes. Both components are electrically and mechanically identical across all functional parameters. The 64-PowerTQFP package geometry, pin configuration, and electrical characteristics are equivalent. Substitution requires no circuit modifications.

Q: What is the difference between TPS2384PAPG4 and TPS2384PAP?

A: The components are functionally identical. TPS2384PAPG4 is discontinued; TPS2384PAP is the active production equivalent. The packaging format differs (standard vs. Tray), which is a procurement and handling specification without impact on component performance.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance, REACH Unaffected status, and MSL ratings. Certifications and regulatory classifications are equivalent.

Q: Is the 64-PowerTQFP package compatible with existing PCB layouts?

A: Yes. Both parts use the identical 64-PowerTQFP (10x10) surface mount package. PCB footprints, solder pad layouts, and thermal characteristics are equivalent. No layout modifications are required.

Q: What is the inventory status for these parts?

A: TPS2384PAPG4 has 776 pieces in stock (discontinued status). TPS2384PAP has 2200 pieces in stock (active production). For new procurement, TPS2384PAP is the recommended source.
