MP2736DQG-LF-P Equivalent & Substitute Parts

Part Overview

The MP2736DQG-LF-P is a 2-circuit SPDT (Single Pole Double Throw) analog switch IC manufactured by Monolithic Power Systems Inc. This interface component operates as a 2:1 multiplexer/demultiplexer with 450mOhm on-state resistance and is housed in a 10-QFN surface mount package. The device is currently in active production status and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product family, enabling component interchangeability for procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

The MP2736DQG-LF-Z is classified as a parametric equivalent to the MP2736DQG-LF-P. Substitution eligibility is determined by strict equivalence across the following critical parameters:

Switch circuit topology (SPDT configuration with 2:1 multiplexing)
Electrical performance specifications (450mOhm on-state resistance, 10mOhm channel matching, 50MHz bandwidth)
Signal integrity characteristics (crosstalk, leakage current, channel capacitance)
Operating conditions (supply voltage range 1.65V ~ 5.5V, temperature range -40°C ~ 85°C)
Physical form factor (10-QFN package, 1.4x1.8mm dimensions, surface mount)
Regulatory compliance (RoHS3, REACH unaffected, MSL 1)

Both parts share identical base product number MP2736 and maintain full electrical and mechanical compatibility. The difference in part number suffix (-LF-P versus -LF-Z) reflects packaging reel configuration or manufacturing date code variations that do not affect functional performance or circuit-level compatibility.

Engineering Selection Recommendations

Both MP2736DQG-LF-P and MP2736DQG-LF-Z are active production components with identical electrical specifications and full regulatory compliance. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences. Both parts maintain RoHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The MP2736DQG-LF-Z currently maintains higher inventory availability (1091 pcs) compared to MP2736DQG-LF-P (760 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can MP2736DQG-LF-Z be used as a direct replacement for MP2736DQG-LF-P in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical performance, package dimensions, and pin configurations. No circuit modifications or re-qualification are required for substitution.

Q: What is the difference between the -LF-P and -LF-Z suffix designations?

A: The suffix variation reflects packaging reel configuration or manufacturing date code differences. Both parts are functionally and electrically identical and share the same base product number MP2736.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, MSL 1 rating, and EAR99 export classification.

Q: What are the critical parameters that define substitution eligibility for MP2736 series switches?

A: Substitution is valid when the following parameters remain constant: SPDT switch topology, 2:1 multiplexing configuration, 450mOhm on-state resistance, 10mOhm channel matching, 50MHz bandwidth, 10-QFN package form factor, and operating temperature range of -40°C to 85°C.

Q: Can these parts be used in applications requiring supply voltages outside the 1.65V ~ 5.5V range?

A: No. Both parts are specified for operation within the 1.65V ~ 5.5V supply voltage range. Operation outside this range is not supported.

Q: What is the significance of the 55pF channel capacitance specification?

A: Channel capacitance affects signal integrity and bandwidth performance in high-frequency applications. The 55pF specification is consistent across both parts and supports the 50MHz -3dB bandwidth rating.
