Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF-USML200-2 is determined by the following critical parameters:

• Voltage rating must equal or exceed 6V maximum
• Current hold (Ih) rating must equal 2A
• Current trip (It) rating must equal 4A
• Package format must be 1210 (3225 Metric), Concave
• Mounting type must be Surface Mount
• Operating temperature range must encompass -40°C ~ 85°C
• Regulatory compliance (RoHS3, cURus, TUV) must be maintained

The substitute part MF-USML200/6-2 meets all critical substitution criteria. This part is manufactured by the same supplier (Bourns Inc.) within the same Multifuse® series and maintains identical electrical ratings for voltage, hold current, and trip current. The part is currently Active in product status, making it suitable for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

The MF-USML200/6-2 is the direct equivalent for the obsolete MF-USML200-2. Both parts share identical electrical specifications, thermal operating range, and regulatory certifications (ROHS3 Compliant, cURus, TUV approved). The primary distinction is product status: MF-USML200/6-2 is Active and available for procurement, while MF-USML200-2 is Obsolete.

For new designs or component replacement in existing applications, MF-USML200/6-2 is the appropriate selection. The packaging format differs (Tape & Reel versus bulk), which may affect procurement and assembly processes but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MF-USML200/6-2 be used as a direct replacement for MF-USML200-2?

A: Yes. Both parts have identical voltage ratings (6V), hold current (2A), trip current (4A), operating temperature range (-40°C ~ 85°C), and package format (1210 Concave). Electrical and mechanical compatibility is confirmed.

Q: What is the difference between MF-USML200-2 and MF-USML200/6-2?

A: The primary difference is product status. MF-USML200-2 is Obsolete, while MF-USML200/6-2 is Active. Secondary differences include packaging format (bulk versus Tape & Reel) and minor variations in post-trip resistance (30 mOhms maximum versus 40 mOhms maximum) and time to trip (3 seconds versus 5 seconds).

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance and are approved by cURus and TUV. Regulatory requirements are identical.

Q: Does the Tape & Reel packaging affect compatibility?

A: No. Tape & Reel packaging is a procurement and assembly format consideration only. It does not affect the electrical or mechanical performance of the component when installed on a PCB.

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

A: Both parts operate across -40°C to 85°C, suitable for industrial and commercial applications.
