Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MF-SMHT160-2-6 are identified based on electrical and mechanical parameter equivalence. The critical parameters that determine substitutability are:

• Voltage rating (16V maximum)
• Current hold specification (1.6 A maximum)
• Current trip specification (3.2 A)
• Resistance characteristics (initial and post-trip)
• Operating temperature range (-40°C ~ 125°C)
• Physical dimensions and mounting type (2-SMD surface mount)
• Compliance certifications (AEC-Q200, ROHS3)

The MF-SMHT160-2 is a parametric equivalent that maintains all electrical and mechanical specifications identical to the MF-SMHT160-2-6. The difference between these parts is limited to packaging configuration, with the substitute available in Tape & Reel (TR) format versus the standard packaging of the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both the MF-SMHT160-2-6 and MF-SMHT160-2 are active production parts from Bourns Inc. with identical electrical performance and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional differences.

The MF-SMHT160-2-6 is suitable for applications requiring standard packaging configurations. The MF-SMHT160-2 in Tape & Reel format is appropriate for high-volume automated assembly processes where reel packaging provides handling and placement efficiency.

Both parts maintain full AEC-Q200 automotive qualification and ROHS3 compliance, ensuring suitability for regulated applications. The polymeric PTC technology provides automatic reset functionality without component replacement after overcurrent events, with consistent performance across the specified operating temperature range of -40°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Are MF-SMHT160-2-6 and MF-SMHT160-2 electrically identical?

A: Yes. Both parts have identical electrical specifications including 16V maximum voltage, 1.6 A hold current, 3.2 A trip current, and 50 mOhms initial resistance. They perform identically in circuit applications.

Q: What is the difference between these part numbers?

A: The primary difference is packaging format. MF-SMHT160-2-6 uses standard packaging, while MF-SMHT160-2 is supplied in Tape & Reel (TR) configuration for automated assembly operations.

Q: Can I use MF-SMHT160-2 as a direct replacement for MF-SMHT160-2-6?

A: Yes, from an electrical and mechanical standpoint. The component footprint, dimensions, and performance are identical. Packaging format differences do not affect circuit compatibility.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both MF-SMHT160-2-6 and MF-SMHT160-2 carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What is the operating temperature range for these parts?

A: Both parts operate across -40°C to 125°C, suitable for automotive and industrial applications.

Q: Do these parts require replacement after a trip event?

A: No. These are polymeric PTC resettable fuses that automatically reset after the overcurrent condition is removed. They do not require component replacement.
