Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MF72-016D13 is determined by the following critical parameters: resistance value (16 Ohms ±20%), maximum steady-state current rating (3 A), resistance at operating current (measured in milliohms), physical diameter, and lead spacing. The substitute part B57211P0160M301 is functionally equivalent based on matching these core electrical and mechanical specifications. Both parts maintain identical resistance values, tolerance ranges, and current ratings. The primary distinction is the physical diameter: the MF72-016D13 measures 0.610" (15.50 mm) while the B57211P0160M301 measures 0.512" (13.00 mm). Both share identical lead spacing of 0.295" (7.50 mm), allowing accommodation in similarly designed circuit layouts. Compliance certifications (RoHS3, REACH, EAR99 ECCN classification) are identical across both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the MF72-016D13 and B57211P0160M301 are Active-status components carrying identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification). Selection between these parts depends on physical space constraints within the target application. The MF72-016D13, with its larger 15.50 mm diameter, may be preferred in applications where component size is less restrictive. The B57211P0160M301, featuring a smaller 13.00 mm diameter, accommodates space-limited designs while maintaining equivalent electrical performance. The resistance variance at operating current (338 mOhms versus 346 mOhms) falls within acceptable engineering tolerance for inrush current limiting applications. Both parts support identical lead spacing (7.50 mm), enabling direct PCB footprint compatibility in most designs.

Frequently Asked Questions (FAQ)

Q: Can B57211P0160M301 be used as a direct replacement for MF72-016D13? A: Electrical substitution is valid. The parts share identical resistance (16 Ohms ±20%), current rating (3 A), and compliance certifications. Mechanical compatibility depends on available PCB space, as the B57211P0160M301 diameter is 0.512" versus the MF72-016D13 at 0.610". Lead spacing is identical at 0.295" (7.50 mm).

Q: What is the significance of resistance @ current (338 mOhms vs 346 mOhms)? A: Resistance at operating current represents the measured resistance under load conditions. The 8 mOhms difference between parts is within acceptable engineering tolerance for inrush current limiting applications and does not prevent electrical substitution.

Q: Are there packaging or supply chain considerations? A: Both parts are available in Bulk packaging and carry Active product status. Inventory availability differs: MF72-016D13 (780 Pcs) versus B57211P0160M301 (1093 Pcs). Selection based on supply chain requirements or delivery lead times is valid.

Q: Do these parts meet current regulatory requirements? A: Both components are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 under export control regulations. Regulatory compliance is equivalent across both parts.

Q: What is the primary design consideration for choosing between these substitutes? A: Physical package diameter is the primary design differentiator. Select based on available PCB space constraints and thermal dissipation requirements within the target application. Electrical performance and compliance certifications are equivalent.
