Substitute Part Grouping Explanation

Substitution eligibility for the MF-R090-1-009 is determined by strict equivalence across the following critical parameters:

• Voltage rating: 60V maximum
• Current hold specification: 900 mA maximum
• Current trip specification: 1.8 A
• Polymeric PTC type classification
• Through-hole radial disc mounting configuration
• Lead spacing: 0.201" (5.10mm)
• Operating temperature range: -40°C ~ 85°C
• Regulatory compliance: cURus, TUV approval

The MF-R090 base part number represents the parametric equivalent within the Multifuse® MF-R series. Substitution is valid when all electrical characteristics and mechanical dimensions remain identical, regardless of packaging format or inventory source.

Parameter Comparison

Engineering Selection Recommendations

Both MF-R090-1-009 and MF-R090 are Active status components from Bourns Inc. with identical electrical and mechanical specifications.

Both parts maintain ROHS3 compliance and carry cURus and TUV regulatory approvals, confirming suitability for applications requiring certified circuit protection. The MF-R090 base part number offers higher inventory availability (3032 Pcs) compared to the MF-R090-1-009 variant (928 Pcs), making it a practical alternative when supply considerations are relevant.

Frequently Asked Questions (FAQ)

Q: Can MF-R090 replace MF-R090-1-009 in existing designs?

A: Yes. Both parts are parametrically identical across all electrical characteristics (voltage, current hold, current trip, resistance values, and time to trip) and mechanical specifications (lead spacing, mounting type, package configuration). Direct substitution is valid without circuit redesign.

Q: What is the difference between MF-R090-1-009 and MF-R090?

A: The primary difference is packaging format. MF-R090-1-009 is supplied in tape and reel packaging, while MF-R090 is supplied in bulk packaging. Electrical and mechanical performance are identical.

Q: Are both parts certified for the same applications?

A: Yes. Both parts carry identical regulatory approvals (cURus, TUV) and maintain ROHS3 compliance and REACH unaffected status, confirming equivalence for certified applications.

Q: What parameters must remain constant for substitution validity?

A: Voltage rating (60V), current hold (900 mA), current trip (1.8 A), polymeric type, through-hole radial disc configuration, and lead spacing (5.10mm) must all remain identical. All these parameters are matched between MF-R090-1-009 and MF-R090.

Q: Can I use these parts interchangeably in PCB assembly?

A: Yes. Both parts feature identical through-hole radial disc configuration with 0.201" (5.10mm) lead spacing, confirming mechanical and electrical interchangeability in PCB designs.
