Engineering Selection Recommendations

All three parts—MF-R075-2-17, MF-R075-2, and MF-R075-AP—are active production components manufactured by Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements:

MF-R075-2-17 (Tape & Reel): Suitable for high-volume automated assembly operations requiring continuous reel feeding. Includes AEC-Q200 automotive qualification and comprehensive approval agency certifications (cUL, cURus, TUV, UL).

MF-R075-2 (Cut Tape): Appropriate for lower-volume production or manual assembly processes. Carries cURus and TUV certifications.

MF-R075-AP (Cut Tape): Appropriate for lower-volume production or manual assembly processes. Carries cURus and TUV certifications. Highest inventory availability (12,880 pcs).

All parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical thermal and electrical performance across the specified operating temperature range of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can MF-R075-2 or MF-R075-AP be used as direct replacements for MF-R075-2-17 in circuit applications?

A: Yes. All three parts share identical electrical specifications (60V maximum voltage, 750 mA hold current, 1.5 A trip current, 6.3 s trip time) and mechanical dimensions (0.409" diameter, 0.201" lead spacing). Substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous reels for automated pick-and-place assembly. Cut Tape packaging provides components in tape strips cut to specific lengths, suitable for manual handling or lower-volume assembly. Both formats contain identical components with no electrical or performance differences.

Q: Are there approval agency differences between these parts?

A: MF-R075-2-17 includes AEC-Q200 automotive qualification and certifications from cUL, cURus, TUV, and UL. MF-R075-2 and MF-R075-AP carry cURus and TUV certifications. Selection depends on application-specific compliance requirements.

Q: Do these parts have the same initial and post-trip resistance values?

A: Yes. All three parts specify 180 mOhms minimum initial resistance (Ri) and 600 mOhms maximum post-trip resistance (R1), ensuring identical circuit behavior during normal operation and fault conditions.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -40°C to 85°C, providing consistent thermal performance across the full specified range.

Q: Are all parts RoHS3 compliant?

A: Yes. MF-R075-2-17, MF-R075-2, and MF-R075-AP are all ROHS3 compliant with REACH unaffected status.
