MUX509IPWR Equivalent & Substitute Parts

Part Overview

The MUX509IPWR is a 2-circuit IC switch with 4:1 multiplexer/demultiplexer functionality manufactured by Texas Instruments. This surface-mount component operates across single supply voltages of 10V to 36V or dual supply voltages of ±5V to ±18V, with an on-state resistance of 170Ohm maximum. The device is classified as Active product status with ROHS3 compliance and Moisture Sensitivity Level 2 (1 Year). Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters including multiplexer circuit configuration, supply voltage ranges, operating temperature, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MUX509IPWR is determined by strict alignment of the following critical parameters:

• Multiplexer/Demultiplexer circuit configuration: 4:1
• Number of circuits: 2
• Package form factor: 16-TSSOP with identical physical dimensions (0.173", 4.40mm Width)
• Supply voltage ranges: Single supply 10V ~ 36V and dual supply ±5V ~ 18V
• Operating temperature range: -40°C ~ 125°C (TA)
• Mounting type: Surface Mount
• Product status: Active
• Regulatory compliance: ROHS3 Compliant

The PS509LEX from Diodes Incorporated satisfies all mandatory substitution criteria. Variations in on-state resistance, switching time, charge injection, and channel capacitance are within acceptable tolerance ranges for this component category and do not preclude functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MUX509IPWR and PS509LEX maintain Active product status with ROHS3 compliance and REACH Unaffected regulatory standing. Selection between these components is based on application-specific requirements and inventory availability. The MUX509IPWR offers lower on-state resistance (170Ohm vs. 200Ohm) and faster switching characteristics (136ns/75ns vs. 210ns/191ns). The PS509LEX provides equivalent functional performance with acceptable parameter variations for standard multiplexing applications. Both devices are suitable for direct substitution in 16-TSSOP surface-mount implementations requiring 4:1 dual-circuit switching across the specified supply and temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can PS509LEX replace MUX509IPWR in existing designs?

A: Yes. Both components share identical 4:1 multiplexer/demultiplexer circuit configuration, dual-circuit topology, 16-TSSOP package dimensions, supply voltage ranges (10V ~ 36V single, ±5V ~ 18V dual), and operating temperature range (-40°C ~ 125°C). Pin-to-pin compatibility and functional equivalence are maintained.

Q: What are the key differences between these parts?

A: The MUX509IPWR has lower on-state resistance (170Ohm vs. 200Ohm), faster switching times (136ns/75ns vs. 210ns/191ns), and lower charge injection (0.3pC vs. 2pC). The PS509LEX exhibits higher channel capacitance values. These differences do not affect functional substitution in standard applications.

Q: Are both parts available in the same packaging?

A: Yes. Both the MUX509IPWR and PS509LEX are packaged in 16-TSSOP (0.173", 4.40mm Width) surface-mount form factor with identical physical dimensions and pin configuration.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Both maintain Active product status.

Q: Which part should be selected for new designs?

A: Selection depends on application performance requirements and supply chain considerations. The MUX509IPWR is preferred for applications requiring lower on-state resistance and faster switching response. The PS509LEX is suitable for standard multiplexing applications where the parameter variations are acceptable.
