Engineering Selection Recommendations

All three parts—MF-SM150-2-006, MF-SM150-2, and PFSM.150.2—are active production components with identical electrical specifications and mechanical form factors. Selection between these parts is based on packaging and availability:

MF-SM150-2-006 and MF-SM150-2 are both Bourns Inc. products with identical performance characteristics. The primary difference is packaging configuration.
PFSM.150.2 is manufactured by SCHURTER Inc. and provides an alternative source with equivalent electrical and mechanical parameters.
All three parts carry AEC-Q200 automotive qualification, cURus and TUV approvals, and ROHS3 compliance, making them suitable for regulated applications.
Component selection should be based on supply chain availability, packaging requirements (tape and reel versus alternative formats), and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can MF-SM150-2 be used as a direct replacement for MF-SM150-2-006?

A: Yes. Both parts are manufactured by Bourns Inc. with identical electrical parameters (15V, 1.5A hold current, 3A trip current), identical physical dimensions (0.344" L x 0.264" W, 0.118" thickness), and identical regulatory certifications (AEC-Q200, cURus, TUV, ROHS3). The parts are functionally equivalent for circuit applications.

Q: Is PFSM.150.2 from SCHURTER compatible with the original MF-SM150-2-006?

A: Yes. PFSM.150.2 meets all electrical and mechanical specifications of MF-SM150-2-006. Both components operate at 15V with 1.5A hold current and 3A trip current, share identical physical dimensions and 2-SMD package form factor, and carry equivalent regulatory approvals (AEC-Q200, cURus, TUV, ROHS3). The component is a parametric equivalent from an alternative manufacturer.

Q: What is the difference between MF-SM150-2-006 and MF-SM150-2?

A: The primary difference is packaging. MF-SM150-2-006 is supplied in individual packaging format, while MF-SM150-2 is supplied in tape and reel (TR) format for automated assembly. Electrical performance and physical dimensions are identical.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification, which certifies suitability for automotive-grade applications. Each part also holds cURus and TUV approvals and maintains ROHS3 compliance.

Q: Can these parts be used interchangeably in high-temperature environments?

A: Yes. All three parts operate across the identical temperature range of -40°C to 85°C. Operating temperature specifications are equivalent across MF-SM150-2-006, MF-SM150-2, and PFSM.150.2.

Q: What is the significance of the 5-second time-to-trip specification?

A: The 5-second time-to-trip parameter defines the maximum duration the fuse will conduct current above its 3A trip threshold before entering the high-resistance protection state. This specification is identical across all three substitute parts.
