Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PFSM.100.2 is determined by strict equivalence across the following critical parameters:

Voltage rating must equal 30V maximum. Current hold (Ih) must equal 1.1A maximum. Current trip (It) must equal 2.2A. Time to trip must equal 500ms. Resistance initial (Ri) minimum must equal 120mOhms. Resistance post-trip (R1) maximum must equal 480mOhms. Operating temperature range must span -40°C to 85°C. Mounting type must be Surface Mount. Package must be 2-SMD. Regulatory compliance must include AEC-Q200 rating and cURus/TUV approval. RoHS status must be ROHS3 Compliant.

The MF-SM100-2 manufactured by Bourns Inc. meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the PFSM.100.2 and MF-SM100-2 are Active product status components with identical electrical and mechanical specifications. Both carry AEC-Q200 automotive qualification and are approved by cURus and TUV. Both are ROHS3 Compliant. The primary distinction is packaging format: PFSM.100.2 is supplied in Tape & Reel (TR), while MF-SM100-2 is available in Cut Tape (CT) & Digi-Reel® format. Selection between these parts should be based on procurement requirements, inventory availability, and packaging compatibility with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MF-SM100-2 be used as a direct replacement for PFSM.100.2?

A: Yes. Both parts share identical electrical characteristics including 30V maximum voltage, 1.1A hold current, 2.2A trip current, and 500ms trip time. Both are qualified to AEC-Q200 and approved by cURus and TUV. Mechanical compatibility is confirmed through matching 2-SMD package, surface mount mounting type, and equivalent dimensions within tolerance.

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

A: PFSM.100.2 is supplied in Tape & Reel (TR) format. MF-SM100-2 is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging options are suitable for automated assembly processes; selection depends on production line compatibility and inventory management requirements.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical regulatory compliance: AEC-Q200 rating, cURus and TUV approval, ROHS3 compliance, and REACH Unaffected status. ECCN and HTSUS classifications are identical.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in voltage rating (30V), current hold (1.1A), current trip (2.2A), time to trip (500ms), initial resistance (120mOhms minimum), post-trip resistance (480mOhms maximum), operating temperature range (-40°C to 85°C), mounting type (Surface Mount), package type (2-SMD), and regulatory certifications (AEC-Q200, cURus, TUV, ROHS3).

Q: Can these parts be used in non-automotive applications?

A: Yes. While both parts carry AEC-Q200 automotive qualification, they are suitable for any application requiring polymeric PTC resettable fuse protection within the specified electrical and thermal parameters.
