Key Parameters

Substitute Part Grouping Explanation

The MF-PSML150/6-2 qualifies as a direct substitute based on the following critical parameters:

• Identical voltage rating: 6V maximum
• Identical initial resistance: 15 mOhms minimum
• Identical operating temperature range: -40°C ~ 85°C
• Identical mounting type and package: Surface Mount, 0805 (2012 Metric), Concave
• Identical physical dimensions: 0.085" L x 0.053" W (2.15mm x 1.35mm)
• Identical compliance certifications: cURus, TUV, ROHS3 Compliant, REACH Unaffected
• Identical moisture sensitivity level: 2A (4 Weeks)

The substitute part maintains all functional and mechanical compatibility parameters required for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The MF-PSML150/6-2 is the appropriate selection for applications currently specified with MF-PSML150-2. The substitute part maintains full electrical and mechanical compatibility across all critical parameters while offering the advantage of active product status and current manufacturing availability.

Both parts carry identical regulatory certifications (cURus, TUV) and compliance designations (ROHS3 Compliant, REACH Unaffected), ensuring equivalent performance in regulated applications. The thickness differential of 0.004" (0.10mm) between the two parts remains within typical PCB assembly tolerances and does not impact functional performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can MF-PSML150/6-2 be used as a direct replacement for MF-PSML150-2?

A: Yes. The MF-PSML150/6-2 is a direct substitute. All critical electrical parameters (voltage, resistance, temperature range), mechanical dimensions, package type, and regulatory certifications are identical or compatible.

Q: What is the difference in thickness between these parts?

A: MF-PSML150-2 has a maximum thickness of 0.024" (0.60mm), while MF-PSML150/6-2 has a maximum thickness of 0.028" (0.70mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not affect circuit performance or board layout.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both MF-PSML150-2 and MF-PSML150/6-2 are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements.

Q: What is the packaging difference between these parts?

A: MF-PSML150-2 is supplied in standard packaging, while MF-PSML150/6-2 is available in Tape & Reel (TR) format. Both use identical 0805 (2012 Metric) surface mount packages with concave geometry.

Q: Why is MF-PSML150-2 listed as Obsolete?

A: MF-PSML150-2 has reached end-of-life status. MF-PSML150/6-2 is the active equivalent part from Bourns Inc. and is recommended for new designs and ongoing procurement.

Q: Are the moisture sensitivity levels the same?

A: Yes. Both parts have identical Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks), requiring the same handling and storage protocols.
