MPC506APG4 Equivalent & Substitute Parts Reference

Part Overview

The MPC506APG4 is a 16:1 analog multiplexer/demultiplexer IC manufactured by Texas Instruments, housed in a 28-DIP package with 1.5kOhm on-state resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part operates across a dual supply voltage range of ±5V to ±22V and features 200ns/250ns switching characteristics suitable for general-purpose signal routing applications.

Substitute Part Grouping Explanation

Substitution of the MPC506APG4 is determined by strict adherence to the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Multiplexer configuration must be 16:1
• Single circuit topology required
• Package must be 28-DIP through-hole format
• Dual supply voltage operation capability
• On-state resistance compatibility within application tolerance

Substitute Parts Identified:

1. DG506ACJ+ (Analog Devices Inc./Maxim Integrated) — Active product status. Meets 16:1 multiplexer configuration and 28-DIP package requirement. On-state resistance of 450Ohm is lower than MPC506APG4, reducing signal path impedance. Dual supply voltage range ±4.5V to ±18V is narrower than the original part but covers standard industrial operating points. Switch time specifications differ (1µs/400ns vs. 200ns/250ns). Leakage current is significantly lower at 5nA. Operating temperature range 0°C to 70°C is narrower than the original.

2. HI3-0506A-5Z (Renesas Electronics Corporation) — Obsolete product status. Meets 16:1 multiplexer configuration and 28-DIP package requirement. On-state resistance of 1.8kOhm is marginally higher than MPC506APG4. Dual supply voltage fixed at ±15V, which falls within the MPC506APG4 operating range. Switch time 300ns/300ns is comparable to the original. Leakage current 30pA is lower than the original. Operating temperature range 0°C to 75°C is narrower than the original.

Parameter Comparison

Engineering Selection Recommendations

DG506ACJ+ Selection Criteria: The DG506ACJ+ is the only active product among the identified substitutes, ensuring long-term availability and manufacturing support. This part is suitable for applications where lower on-state resistance (450Ohm vs. 1.5kOhm) provides signal integrity advantages and reduced power dissipation. The narrower supply voltage range (±4.5V to ±18V) requires verification against system power supply specifications. The slower turn-on time (1µs vs. 200ns) may impact applications with stringent switching speed requirements. Operating temperature range limitation (0°C to 70°C) excludes extended-temperature applications. ROHS3 compliance and unlimited moisture sensitivity level (MSL-1) support modern manufacturing and storage requirements.

HI3-0506A-5Z Selection Criteria: The HI3-0506A-5Z maintains closer electrical parity to the MPC506APG4, with on-state resistance within 20% tolerance and comparable switching characteristics. Fixed dual supply voltage at ±15V is suitable for standard industrial systems operating within this specification. The narrower operating temperature range (0°C to 75°C) excludes extended-temperature applications. Obsolete product status limits future availability; this part is appropriate only for legacy system maintenance or where existing inventory is available. ROHS3 compliance and unlimited MSL-1 rating support standard manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can DG506ACJ+ directly replace MPC506APG4 in all applications? A: Direct replacement requires verification of three parameters: (1) system supply voltage must fall within ±4.5V to ±18V range, (2) application switching speed tolerance must accommodate 1µs turn-on time, and (3) operating temperature must remain within 0°C to 70°C. If any parameter falls outside these bounds, substitution is not recommended.

Q: What is the significance of on-state resistance differences between these parts? A: On-state resistance directly affects signal path impedance and power dissipation. DG506ACJ+ at 450Ohm provides lower impedance than MPC506APG4 at 1.5kOhm, reducing signal attenuation and heat generation. HI3-0506A-5Z at 1.8kOhm is marginally higher, introducing slightly greater impedance. Selection depends on application signal levels and thermal constraints.

Q: Are all three parts pin-compatible? A: All three parts use 28-DIP package format with identical physical dimensions (0.600", 15.24mm). Pin compatibility for 16:1 multiplexer function is maintained across all three devices. PCB layout modifications are not required for package substitution.

Q: Why is DG506ACJ+ recommended despite slower switching speed? A: DG506ACJ+ is the only active product with guaranteed long-term availability and manufacturing support. For applications where 1µs switching time is acceptable, this part eliminates obsolescence risk. For applications requiring faster switching, HI3-0506A-5Z at 300ns provides closer performance match, though with obsolete product status.

Q: What compliance certifications apply to all substitute parts? A: All three parts carry ROHS3 compliance and EAR99 export classification. DG506ACJ+ provides unlimited moisture sensitivity level (MSL-1), while MPC506APG4 and HI3-0506A-5Z specify MSL-1 with 1-year shelf life. All parts are REACH Unaffected.

Q: Can HI3-0506A-5Z be used in applications requiring extended temperature operation? A: No. HI3-0506A-5Z operating range is 0°C to 75°C, which excludes the lower temperature extreme of MPC506APG4 (-40°C). Applications requiring -40°C operation must retain the original MPC506APG4 or identify alternative sources.
