Key Parameters

Substitute Part Grouping Explanation

Substitution of inrush current limiters is determined by the following critical parameters:

• Steady-State Current Rating: Both the main part and substitute must support the same maximum continuous current (10 A in this case)
• Tolerance: Both parts maintain ±20% tolerance specification
• RoHS Compliance: Both parts are ROHS3 compliant
• Product Status: Both parts are Active status, ensuring ongoing availability and support
• Regulatory Compliance: Both parts are REACH Unaffected

The MF72-001.5D25 from Cantherm qualifies as a substitute based on matching steady-state current rating (10 A), tolerance (±20%), RoHS compliance (ROHS3), and active product status. Differences in resistance value (1.5 Ohms vs. 7 Ohms) and physical dimensions reflect design variations within the inrush current limiter category and must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the SL22 7R010 and MF72-001.5D25 are Active products with ROHS3 compliance and REACH Unaffected status, making them suitable for applications requiring regulatory compliance. The SL22 7R010 carries CSA and UR approvals. Selection between these parts should be based on circuit-specific resistance requirements, available board space for the different form factors (22mm vs. 27.5mm diameter), and lead spacing compatibility (7.80mm vs. 10.00mm).

Frequently Asked Questions (FAQ)

Q: What determines if MF72-001.5D25 can substitute for SL22 7R010?

A: Both parts share the same steady-state current rating (10 A), tolerance specification (±20%), RoHS compliance level (ROHS3), and active product status. These are the primary substitution criteria for inrush current limiters.

Q: How do the resistance values differ between these parts?

A: The SL22 7R010 has 7 Ohms resistance at 25°C, while the MF72-001.5D25 has 1.5 Ohms. This difference affects circuit behavior and must be evaluated against application requirements.

Q: Are there physical compatibility concerns?

A: Yes. The SL22 7R010 has a 22mm diameter with 7.80mm lead spacing, while the MF72-001.5D25 has a 27.5mm diameter with 10.00mm lead spacing. Board layout and footprint compatibility must be confirmed before substitution.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH Unaffected. The SL22 7R010 carries CSA and UR approvals, while the MF72-001.5D25 does not list specific approval agencies.

Q: What is the difference in resistance at operating current?

A: The SL22 7R010 exhibits 80 mOhms at operating current, while the MF72-001.5D25 exhibits 27 mOhms. This affects power dissipation and thermal characteristics in the circuit.
