• Programmable Circuit Breaker: Current limiting and fault isolation capability
• Supply Voltage Range: 3.3V, 5V, and ±12V multi-rail support
• Output Current Ratings: 100mA, 375mA, and 500mA channel specifications
• Thermal Operating Range: -40°C to 85°C
• Package Specification: 80-HTQFP (12x12) form factor with exposed pad
• Regulatory Compliance: ROHS3 and REACH compliance status

Parameter Comparison

Engineering Selection Recommendations

The TPS2340APFPR represents a direct functional equivalent to the TPS2340APFP. Both devices maintain identical electrical specifications, package geometry, and regulatory compliance certifications. The TPS2340APFPR is currently discontinued at DiGi Electronics, while the TPS2340APFP is classified as obsolete. For applications requiring the TPS2340 series hot plug controller functionality, component selection should prioritize availability through authorized Texas Instruments distributors and verified inventory channels. Both parts satisfy ROHS3 and REACH compliance requirements for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the TPS2340APFPR be used as a direct replacement for the TPS2340APFP?

A: Yes. Both devices are electrically and mechanically identical across all specified parameters, including channel count, switching architecture, protection features, supply voltage ranges, output current ratings, operating temperature range, and package specification (80-HTQFP 12x12).

Q: Are there any package or pinout differences between these parts?

A: No. Both the TPS2340APFP and TPS2340APFPR use the 80-TQFP Exposed Pad package with 80-HTQFP (12x12) supplier device package specification. Pinout and mechanical dimensions are identical.

Q: What is the significance of the different product status designations?

A: The TPS2340APFP is classified as obsolete, while the TPS2340APFPR is discontinued at DiGi Electronics. Both statuses indicate limited or no availability through standard distribution channels. Component sourcing should focus on authorized Texas Instruments distributors or verified secondary market inventory.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the TPS2340APFP and TPS2340APFPR are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What are the critical parameters for substitution eligibility?

A: Substitution requires matching across five-channel architecture, dual internal switching capability, PCI/PCI-X application support, latched fault and thermal protection features, programmable circuit breaker functionality, multi-rail supply voltage support (3.3V, 5V, ±12V), specified output current ratings (100mA, 375mA, 500mA), operating temperature range (-40°C to 85°C), and 80-HTQFP (12x12) package specification.
