MPC506AUG4 Equivalent & Substitute Parts

Part Overview

The MPC506AUG4 is a 16:1 analog multiplexer/demultiplexer IC manufactured by Texas Instruments, housed in a 28-SOIC surface mount package. This component functions as a single-circuit switch with 1.5kOhm on-state resistance, designed for signal routing applications requiring low on-resistance and fast switching characteristics. The MPC506AUG4 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives with compatible electrical and mechanical specifications are available from Texas Instruments and Renesas Electronics Corporation.

Parameter Comparison

Engineering Selection Recommendations

MPC506AU (Texas Instruments) is the primary recommended substitute for the discontinued MPC506AUG4. This part maintains identical electrical specifications including on-state resistance, supply voltage range, switch timing, and channel capacitance. Both parts are manufactured by Texas Instruments and share the same base product number (MPC506). The MPC506AU is currently in active production status with established inventory availability. Packaging is supplied in tube format. Moisture sensitivity level and RoHS3 compliance are identical to the original part.

HI9P0506-9Z (Renesas Electronics Corporation) is an alternative substitute suitable for applications where improved performance characteristics are acceptable. This part offers superior on-state resistance (400Ohm versus 1.5kOhm), resulting in lower signal attenuation and reduced power dissipation. Leakage current is significantly lower (30pA versus 500pA). The supply voltage specification is limited to ±15V, which may restrict use in applications requiring the full ±5V ~ 22V range of the original part. Moisture sensitivity level is MSL 3 (168 Hours), requiring more stringent handling procedures compared to MSL 2 parts. This substitute is suitable for designs where the narrower voltage range and higher MSL classification are acceptable trade-offs for improved electrical performance.

Frequently Asked Questions (FAQ)

Q: Can MPC506AU be used as a direct replacement for MPC506AUG4?

A: Yes. The MPC506AU is a direct electrical and mechanical equivalent. Both parts feature identical 16:1 multiplexer configuration, 1.5kOhm on-state resistance, ±5V ~ 22V dual supply voltage range, 28-SOIC package, and operating temperature specifications. The primary difference is product status: MPC506AUG4 is discontinued while MPC506AU is in active production.

Q: What are the key differences between MPC506AU and HI9P0506-9Z?

A: The HI9P0506-9Z offers lower on-state resistance (400Ohm versus 1.5kOhm) and significantly lower leakage current (30pA versus 500pA). However, the supply voltage range is limited to ±15V, compared to the ±5V ~ 22V range of MPC506AU. Additionally, HI9P0506-9Z has a higher moisture sensitivity level (MSL 3 versus MSL 2), requiring more careful handling and storage conditions.

Q: Are all substitute parts in the same 28-SOIC package?

A: Yes. MPC506AUG4, MPC506AU, and HI9P0506-9Z are all housed in 28-SOIC (0.295", 7.50mm Width) surface mount packages. PCB layout and footprint compatibility are maintained across all three parts.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. MPC506AUG4, MPC506AU, and HI9P0506-9Z are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute should be selected for new designs?

A: For new designs requiring specifications identical to the original MPC506AUG4, select MPC506AU. For applications where improved on-state resistance and leakage current performance are beneficial and the ±15V supply voltage range is sufficient, HI9P0506-9Z is a viable alternative. Verify that the narrower voltage range and higher moisture sensitivity level of HI9P0506-9Z are compatible with your application requirements.

Q: What is the impact of different moisture sensitivity levels?

A: MPC506AU has MSL 2 (1 Year), allowing one year of floor life after moisture barrier bag opening. HI9P0506-9Z has MSL 3 (168 Hours), limiting floor life to 168 hours after bag opening. MSL 3 components require more stringent moisture control during assembly and storage to prevent moisture absorption that could cause solder joint failures during reflow.
