Equivalent & Substitute Parts for MPDTY122S

Part Overview

The Murata Power Solutions MPDTY122S is a DC DC converter designed for non-isolated point-of-load applications, delivering a single output of 1.2V at up to 6A from a regulated 4.5V–5.5V input. The device is classified as obsolete, necessitating the identification of alternative model numbers for ongoing product support, repair, or design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for DC DC converter modules are determined by strict matching of core electrical and mechanical parameters. The allowed substitution logic for MPDTY122S includes:

• Type (Non-Isolated PoL Module)
• Number of Outputs (1)
• Input Voltage Range (4.5V–5.5V)
• Output Voltage (single, adjustable or fixed within required range)
• Maximum Output Current (6A)
• Mounting Type (Surface Mount)
• Package/Case and Size/Dimension
• Operating Temperature Range (-40°C ~ 85°C)
• Compliance and Certifications (REACH Status, ECCN, HTSUS, RoHS if available)
• Product Status (active or obsolete)
• Features (Remote On/Off, protection features)

Only substitute parts meeting all these criteria are considered suitable replacements.

Parameter Comparison

Engineering Selection Recommendations

Select substitute parts based on matching product status, compliance, and certification criteria. For obsolete modules such as MPDTY122S, use active alternatives that provide comparable electrical and mechanical characteristics, verified by REACH status, MSL level, and ECCN/HTSUS codes as specified. Substitute parts listed meet the provided certification and compliance requirements.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters are critical for substituting a non-isolated PoL DC DC converter?
A1: Substitution must be based on the number of outputs, input voltage range, output voltage, and maximum output current.

Q2: Are mounting type and package/case important for compatibility?
A2: Yes, mounting type and physical package/case dimensions must match the original module to ensure PCB and mechanical compatibility.

Q3: What compliance and certification criteria must be matched?
A3: Substitute parts must have equivalent REACH status, ECCN, and HTSUS codes. RoHS compliance should be noted when provided.

Q4: Is operating temperature range essential for substitution?
A4: Yes, the substitute must operate within the same temperature range (–40°C to 85°C) for consistent system performance.

Q5: How is output voltage handled if the substitute offers an adjustable range?
A5: The substitute’s output voltage range must include the specified output voltage of the original part.

Q6: Is it acceptable to select an active part as a substitute for an obsolete component?
A6: Yes, selecting an active substitute that meets all required parameters and certifications is suitable for continued product use.
