Key Parameters

Substitute Part Grouping Explanation

Substitution for the MF-PSML110-2 is determined by the following critical parameters:

• Voltage rating: 6V maximum
• Package / Case: 0805 (2012 Metric), Concave
• Mounting Type: Surface Mount
• Operating Temperature: -40°C ~ 85°C
• Approval certifications: cURus and TUV
• RoHS compliance: ROHS3 Compliant

The substitute part MF-PSML110/6-2 maintains identical voltage, package, mounting type, operating temperature range, and regulatory compliance. While the substitute exhibits different electrical characteristics (higher hold current, trip current, and post-trip resistance), these parameters fall within the allowed substitution criteria for the Multifuse® MF-PSML series in the 0805 form factor.

Parameter Comparison

Engineering Selection Recommendations

The MF-PSML110/6-2 is the direct substitute for the obsolete MF-PSML110-2. Both components share identical voltage ratings, package specifications, mounting configurations, and regulatory certifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Selection of the MF-PSML110/6-2 is supported by:

• Identical 6V voltage rating and 0805 surface mount package
• Matching operating temperature range of -40°C to 85°C
• Equivalent ROHS3 compliance and regulatory approvals (cURus, TUV)
• Same moisture sensitivity level (2A, 4 Weeks)
• Active product status providing long-term supply continuity

The substitute exhibits increased initial resistance (30 mOhms versus 17.5 mOhms) and includes specified hold current (1.1 A), trip current (2.2 A), and post-trip resistance (210 mOhms) parameters. These electrical characteristics are within the allowed substitution parameters for the Multifuse® MF-PSML series.

Frequently Asked Questions (FAQ)

Q: Can MF-PSML110/6-2 be used as a direct replacement for MF-PSML110-2?

A: Yes. Both components share identical voltage ratings (6V), package specifications (0805 Concave), mounting type (Surface Mount), operating temperature range (-40°C to 85°C), and regulatory certifications (cURus, TUV, ROHS3). The substitute is the designated replacement for the obsolete part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Obsolete versus Active) and electrical characteristics. The substitute MF-PSML110/6-2 specifies hold current (1.1 A), trip current (2.2 A), and post-trip resistance (210 mOhms), while the original part lists only minimum initial resistance. The substitute also has a slightly increased maximum thickness (0.028" versus 0.024").

Q: Are there any package or footprint compatibility concerns?

A: No. Both parts use the identical 0805 (2012 Metric) Concave package with matching dimensions (0.085" L x 0.053" W). PCB footprints and assembly processes remain unchanged.

Q: Does the substitute maintain the same regulatory compliance?

A: Yes. The MF-PSML110/6-2 carries identical approvals: cURus, TUV, ROHS3 Compliant, and REACH Unaffected status. Moisture sensitivity level is also equivalent (2A, 4 Weeks).

Q: Why is the original part obsolete?

A: The MF-PSML110-2 has been discontinued by Bourns Inc. The MF-PSML110/6-2 is the active replacement within the Multifuse® MF-PSML series, providing equivalent functionality with continued manufacturing support.
