MF72-016D15 Equivalent & Substitute Parts

Part Overview

The MF72-016D15 is an Inrush Current Limiter (ICL) manufactured by Cantherm, rated at 16 Ohms with ±20% tolerance and a maximum steady-state current of 4 A. The component features a 0.689" (17.50mm) diameter with 0.394" (10.00mm) lead spacing. This product is Active in status and RoHS3 compliant. Alternative models may be required due to lead spacing constraints, board layout requirements, or supplier availability while maintaining equivalent electrical performance.

Key Parameters

Substitute Part Grouping Explanation

The SL22 16004 manufactured by Ametherm qualifies as a substitute for the MF72-016D15 based on matching electrical parameters. Both components share the following critical substitution criteria:

• Resistance @ 25°C: 16 Ohms (identical)
• Tolerance: ±20% (identical)
• Current - Steady State Max: 4 A (identical)
• RoHS3 Compliance (both compliant)
• REACH Status: REACH Unaffected (both unaffected)
• ECCN Classification: EAR99 (identical)
• HTSUS Code: 8533.40.8070 (identical)

The SL22 16004 differs in physical dimensions (0.866" / 22.00mm diameter and 0.307" / 7.80mm lead spacing) and includes CSA approval. These differences require mechanical and layout validation during component selection.

Parameter Comparison

Engineering Selection Recommendations

Both the MF72-016D15 and SL22 16004 are Active status products with RoHS3 compliance and REACH Unaffected designation, making them suitable for applications requiring environmental compliance. The MF72-016D15 is available with 701 pieces in stock, while the SL22 16004 offers higher availability at 1200 pieces. The SL22 16004 carries CSA approval, which may be required for specific regulatory jurisdictions. Component selection should account for physical dimensions and board layout constraints, as the SL22 16004 has a larger diameter and different lead spacing than the MF72-016D15.

Frequently Asked Questions (FAQ)

Q: Can the SL22 16004 directly replace the MF72-016D15 in existing assemblies?

A: Electrical compatibility is established through matching resistance, tolerance, and current ratings. However, physical dimensions differ: the SL22 16004 has a larger diameter (0.866" vs 0.689") and tighter lead spacing (0.307" vs 0.394"). Board layout and mounting hole spacing must be evaluated before substitution.

Q: What are the critical parameters for ICL substitution?

A: Resistance at 25°C, tolerance, and maximum steady-state current must match. Both parts meet these criteria at 16 Ohms ±20% and 4 A. Resistance at operating current differs slightly (276 mOhms vs 250 mOhms) and may affect thermal performance.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS3 compliant and REACH unaffected. The SL22 16004 includes CSA approval, which the MF72-016D15 does not list. CSA approval may be mandatory for certain applications or markets.

Q: Does packaging affect component selection?

A: Both parts are supplied in Bulk packaging. Availability differs: 701 pieces for MF72-016D15 versus 1200 pieces for SL22 16004. Lead spacing differences (0.394" vs 0.307") may impact PCB design and soldering processes.

Q: How do the resistance values at operating current affect performance?

A: The MF72-016D15 exhibits 276 mOhms at rated current, while the SL22 16004 exhibits 250 mOhms. This 26 mOhm difference influences heat dissipation and steady-state voltage drop across the component.
