MF72-016D25 Equivalent & Substitute Parts

Part Overview

The MF72-016D25 is an inrush current limiter manufactured by Cantherm, rated at 16 Ohms ±20% with a steady-state maximum current of 6 A and a physical diameter of 1.083" (27.50mm). This component is classified as active and ROHS3 compliant. Alternative models become necessary when application requirements exceed the voltage or current specifications of the primary component, when physical space constraints demand smaller form factors, or when procurement requirements necessitate equivalent devices from alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MF72-016D25 is governed by the following core parameters:

• Resistance Range (16 Ohms ±20%): Substitute components must fall within 12.8 to 19.2 Ohms to maintain equivalent inrush limiting behavior
• Steady-State Maximum Current: Substitute components must support at least 6 A to meet or exceed the original specification
• Physical Form Factor: The 1.083" (27.50mm) diameter and 0.394" (10.00mm) lead spacing define mechanical compatibility; substitutes with different dimensions may require circuit board redesign
• Regulatory Compliance: All substitutes must maintain ROHS3 compliance and REACH unaffected status

Three substitute components have been identified. The MS32 20008 and MS32 20010 (both Ametherm MegaSurge™ series) feature 20 Ohms resistance with higher current ratings of 8 A and 10 A respectively, suitable for applications requiring increased current capacity. The SL22 14007 (Ametherm SL22 series) provides 14 Ohms resistance with 7 A capacity in a compact 0.866" (22.00mm) form factor.

Parameter Comparison

Engineering Selection Recommendations

MS32 20008: Suitable for applications where current capacity must increase to 8 A while maintaining active product status and ROHS3 compliance. The 20 Ohms resistance is slightly elevated from the original specification, resulting in different inrush limiting characteristics. Physical dimensions increase to 1.220" (31.00mm) diameter. UL agency approval is present.

MS32 20010: Appropriate for designs requiring maximum steady-state current of 10 A with active product status and ROHS3 compliance. The 20 Ohms resistance and 1.220" (31.00mm) diameter represent the same trade-offs as MS32 20008. This option provides the highest current rating among available substitutes. UL agency approval is present.

SL22 14007: Recommended for applications where physical space is constrained and a smaller 0.866" (22.00mm) form factor is beneficial. The 14 Ohms resistance approximates the original specification more closely than the MegaSurge™ alternatives. Steady-state maximum current of 7 A exceeds the original 6 A requirement. All regulatory and compliance attributes align with the MF72-016D25. CSA agency approval is present.

Frequently Asked Questions (FAQ)

Q: Can MS32 20008 or MS32 20010 be used in place of MF72-016D25? A: Both MS32 models are electrically compatible substitutes with higher current ratings (8 A and 10 A respectively) and similar resistance values (20 Ohms vs. 16 Ohms). However, the larger physical diameter (1.220" vs. 1.083") requires board-level assessment for mechanical fit. Lead spacing differences (0.307" vs. 0.394") may necessitate footprint adjustment.

Q: What are the advantages of selecting SL22 14007? A: The SL22 14007 offers a more compact form factor at 0.866" (22.00mm) diameter and a resistance value (14 Ohms) closer to the original specification. Current rating of 7 A meets or exceeds the 6 A requirement. This option is optimal when space constraints prohibit the use of larger diameter components.

Q: How do resistance tolerances affect component selection? A: The MF72-016D25 specifies ±20% tolerance, while all substitute options specify ±25%. This wider tolerance range in the substitutes must be evaluated within the circuit design margins. At the extreme limits, MF72-016D25 ranges from 12.8 to 19.2 Ohms, while substitutes range from tolerance-adjusted values around their specified nominal ratings.

Q: Are all substitutes ROHS3 compliant? A: Yes. The MF72-016D25 and all three substitute components (MS32 20008, MS32 20010, and SL22 14007) are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment for environmental and hazardous substance restrictions.

Q: Which substitute offers the best inventory availability? A: The SL22 14007 has the highest inventory level at 4672 Pcs New Original In Stock, followed by MS32 20010 at 2787 Pcs, MS32 20008 at 1158 Pcs, and the original MF72-016D25 at 1114 Pcs.
