Substitute Part Grouping Explanation

Substitution of MF-PSML200-2 with MF-PSML200/6-2 is valid based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Voltage Rating: Both rated 6V maximum
• Current Hold (Ih): Both rated 2A
• Package Type: Both 0805 (2012 Metric), Concave
• Physical Dimensions: Identical length and width (0.085" L x 0.053" W / 2.15mm x 1.35mm)
• Operating Temperature Range: Both -40°C ~ 85°C
• Polymeric Type: Both utilize polymeric PTC technology
• Compliance: Both ROHS3 Compliant with cURus and TUV approval

The substitute part MF-PSML200/6-2 maintains Active product status, ensuring long-term availability and supply chain reliability compared to the Obsolete MF-PSML200-2.

Parameter Comparison

Engineering Selection Recommendations

MF-PSML200/6-2 is the direct equivalent for MF-PSML200-2 applications. Selection of the substitute part is justified by:

• Product Status Transition: MF-PSML200/6-2 maintains Active status, eliminating obsolescence risk and ensuring continued procurement availability.
• Electrical Equivalence: Identical voltage rating (6V), current hold rating (2A), and operating temperature range (-40°C ~ 85°C) ensure functional compatibility in existing circuit designs.
• Mechanical Compatibility: Identical package type (0805 / 2012 Metric, Concave) and footprint dimensions (0.085" L x 0.053" W) permit direct PCB layout reuse without redesign.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and carry cURus and TUV approvals, satisfying industrial and consumer application requirements.
• Packaging Availability: MF-PSML200/6-2 is supplied in Tape & Reel format with current inventory, supporting production workflows.

Note: MF-PSML200/6-2 exhibits increased thickness (0.055" vs. 0.024" maximum), which must be verified against PCB assembly clearance specifications and component placement constraints.

Frequently Asked Questions (FAQ)

Q: Can MF-PSML200/6-2 directly replace MF-PSML200-2 in existing designs?

A: Yes. Both parts share identical voltage rating (6V), current hold rating (2A), package type (0805 / 2012 Metric, Concave), and physical footprint dimensions. PCB layout and schematic integration require no modification.

Q: What is the significance of the thickness difference between these parts?

A: MF-PSML200-2 specifies maximum thickness of 0.024" (0.60mm), while MF-PSML200/6-2 specifies 0.055" (1.40mm). This difference must be evaluated against PCB assembly clearance, component stacking height, and enclosure constraints. Verify that increased thickness does not conflict with mechanical design requirements.

Q: Why is MF-PSML200-2 classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. MF-PSML200/6-2 provides functional equivalence with Active status, ensuring long-term supply chain reliability and technical support.

Q: Are the regulatory certifications identical between these parts?

A: Yes. Both parts carry cURus and TUV approvals and maintain ROHS3 compliance. Moisture Sensitivity Level (MSL) is identical at 2A (4 Weeks) for both parts.

Q: What additional electrical parameters are specified for MF-PSML200/6-2?

A: MF-PSML200/6-2 provides complete electrical characterization including Current Trip (It) of 4A, maximum current of 50A, time to trip of 2 seconds, initial resistance (Ri) minimum of 5 mOhms, and post-trip resistance (R1) maximum of 50 mOhms. These parameters were not specified for the obsolete MF-PSML200-2.

Q: What packaging format is available for MF-PSML200/6-2?

A: MF-PSML200/6-2 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Current inventory availability is 8992 pieces.
