Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF-R090-AP-9 is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and its substitute is packaging configuration. The MF-R090-AP-9 is supplied in Tape & Box (TB) packaging, while the MF-R090-AP substitute is supplied in Cut Tape (CT) packaging. Both parts share identical specifications across voltage rating, current ratings, resistance characteristics, temperature range, physical dimensions, lead spacing, and regulatory compliance. Substitution is valid when packaging format does not constrain the application requirement, as the electrical and mechanical performance remains unchanged.

Parameter Comparison

Engineering Selection Recommendations

Both MF-R090-AP-9 and MF-R090-AP are Active status components from Bourns Inc. with identical electrical performance and regulatory compliance. Selection between these parts should be based on packaging requirements and supply chain logistics. The MF-R090-AP-9 in Tape & Box packaging is suitable for applications requiring bulk quantities with protective packaging. The MF-R090-AP in Cut Tape packaging is suitable for automated assembly processes and applications with moderate volume requirements. Both parts maintain ROHS3 compliance and carry cURus and TUV approvals, ensuring equivalent regulatory standing for circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can MF-R090-AP be used as a direct replacement for MF-R090-AP-9?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: MF-R090-AP-9 uses Tape & Box (TB) while MF-R090-AP uses Cut Tape (CT). Substitution is valid when packaging does not constrain the application.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box packaging provides components on tape with protective box containment, suitable for bulk storage and manual handling. Cut Tape packaging provides components on tape without box containment, optimized for automated pick-and-place assembly equipment.

Q: Are the electrical specifications identical between MF-R090-AP-9 and MF-R090-AP?

A: Yes. Both parts share identical voltage rating (60V), current ratings (900 mA hold, 1.8 A trip, 40 A maximum), resistance characteristics (140 mOhms initial, 470 mOhms post-trip), time to trip (7.2 s), and operating temperature range (-40°C ~ 85°C).

Q: Do both parts have the same physical dimensions?

A: Yes. Both parts have identical through-hole radial disc configuration with dimensions of 0.461" L x 0.122" W (11.70mm x 3.10mm), seated height of 0.657" (16.70mm), and lead spacing of 0.201" (5.10mm).

Q: Are both parts RoHS compliant?

A: Yes. Both MF-R090-AP-9 and MF-R090-AP are ROHS3 compliant and carry cURus and TUV approvals.
