LM5070MTC-50 Equivalent & Substitute Parts Reference

Part Overview

The LM5070MTC-50 from Texas Instruments is a Power Management Integrated Circuit (PMIC) operating as a Power Over Ethernet Controller supporting 802.3af (PoE) standards, configured for a single channel and housed in a 16-TSSOP package. With a supply voltage range of 1.8V to 75V and an operating temperature range of -40°C to 125°C, it is suitable for industrial and commercial PoE applications. This specific part is discontinued at major distributors, necessitating the identification of substitute parts with matching key parameters for continued design support or maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute components are selected strictly according to key electrical and mechanical parameters: category, manufacturer, description, number of channels, function type, internal switch configuration, auxiliary sense function, supported standard, supply voltage range, operating temperature, mounting type, package/case, supplier device package, and compliance/certification (RoHS, MSL, REACH). Only devices matching all these specified values are included as equivalents. Variations in other parameters or features are not considered or permitted for substitution.

Parameter Comparison

Engineering Selection Recommendations

The LM5070MTC-50 is discontinued. The LM5070MTC-50/NOPB from Texas Instruments matches all key functional and mechanical parameters and remains active. The LM5070MTC-50/NOPB is ROHS3 compliant, while the original LM5070MTC-50 is RoHS non-compliant. Product selection can be made based on desired RoHS compliance and active lifecycle status.

Frequently Asked Questions (FAQ)

Q: What criteria must be met for a part to be considered a valid substitute for the LM5070MTC-50?
A: All key parameters must match, including manufacturer, category, electrical specifications (channels, supply voltage, standards, function type), mechanical footprint (package, mounting), and certifications (RoHS, REACH, MSL).

Q: Is the LM5070MTC-50/NOPB pin-to-pin compatible with the LM5070MTC-50?
A: Both parts share the 16-TSSOP package and all defined mechanical parameters, permitting direct substitution.

Q: Are there differences in compliance status between the LM5070MTC-50 and LM5070MTC-50/NOPB?
A: The LM5070MTC-50/NOPB is ROHS3 compliant, while the LM5070MTC-50 is RoHS non-compliant. Both are REACH unaffected and MSL 1.

Q: Does the substitute part require any changes to board layout or assembly processes?
A: No changes are required, as all relevant package and mounting parameters are identical according to provided data.

Q: Can both devices operate in the full industrial temperature range?
A: Yes, both parts specify an operating temperature of -40°C to 125°C.
