Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PICOASMDCH010F-2 are qualified based on matching the following critical electrical and mechanical parameters:

• Voltage rating: 16V maximum
• Hold current: 100 mA maximum
• Trip current: 600 mA
• Time to trip: 1.5 seconds
• Package: 0805 (2012 Metric), Concave
• Mounting: Surface Mount
• Operating temperature range: -40°C to 125°C
• RoHS3 compliance
• AEC-Q200 qualification

Two substitute parts meet these criteria: 0ZTK0010FF2G (Bel Fuse Inc.) and PTSAHT080516V010 (Eaton - Electronics Division).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and meet AEC-Q200 automotive qualification requirements. The PICOASMDCH010F-2 and PTSAHT080516V010 share identical post-trip resistance specifications (10 Ohms maximum), while the 0ZTK0010FF2G specifies 12 Ohms maximum post-trip resistance. The PTSAHT080516V010 offers superior moisture handling with MSL 1 (Unlimited) compared to MSL 2A (4 Weeks) for the other two parts. All substitute parts are ROHS3 compliant and carry REACH Unaffected status where specified.

Frequently Asked Questions (FAQ)

Q: Can 0ZTK0010FF2G be used as a direct replacement for PICOASMDCH010F-2?

A: Yes. Both parts share identical electrical ratings (16V, 100 mA hold current, 600 mA trip current, 1.5 s trip time), package geometry (0805 Concave), and operating temperature range (-40°C to 125°C). The post-trip resistance differs by 2 Ohms maximum (10 Ohms vs. 12 Ohms), which remains within acceptable tolerance for PTC resettable fuse applications.

Q: What is the difference between PTSAHT080516V010 and the other substitutes?

A: PTSAHT080516V010 provides improved moisture handling with MSL 1 (Unlimited) versus MSL 2A (4 Weeks) for the other parts. All electrical parameters and package specifications remain equivalent across the three parts.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification, meeting automotive industry reliability and quality standards.

Q: Do dimensional variations between parts affect PCB assembly?

A: Dimensional variations are minimal. The 0805 (2012 Metric) Concave package specification is consistent across all three parts. Length ranges from 2.10mm to 2.25mm, width from 1.35mm to 1.50mm, and thickness from 0.78mm to 0.80mm. These variations fall within standard PCB pad tolerances for 0805 components.
