Engineering Selection Recommendations

All four parts—0215005.MXK7SPP, 0215005.MXF160SPP, 0215005.MXF162SPP, and 0215005.MXF34P—are Active products manufactured by Littelfuse Inc. and are ROHS3 Compliant. They are electrically and mechanically equivalent for 5A 250VAC ceramic radial fuse applications.

Part 0215005.MXF162SPP carries the broadest regulatory approval scope (CE, CQC, CSA, KC, PSE, UR, VDE), making it suitable for applications requiring multiple international certifications. Part 0215005.MXF34P includes UL and SEMKO approvals in addition to CE, CSA, KC, PSE, and VDE, supporting North American and European compliance requirements. Parts 0215005.MXK7SPP and 0215005.MXF160SPP do not specify approval agencies in the provided data.

Selection should be based on specific regulatory requirements for the end application and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 0215005.MXF160SPP, 0215005.MXF162SPP, and 0215005.MXF34P be used interchangeably with 0215005.MXK7SPP?

A: Yes. All parts share identical electrical ratings (5A, 250VAC), response time (Slow Blow), thermal characteristics (Melting I²t: 66.095), mechanical dimensions (0.205" Dia x 0.787" L), and breaking capacity (1.5kA). They are functionally equivalent for through-hole radial ceramic fuse applications.

Q: What is the difference between the 215 and 215SP series designations?

A: The series designation reflects internal Littelfuse product line organization. Both series meet the same electrical and mechanical specifications for this 5A 250VAC application. Series designation does not affect functional compatibility.

Q: Are there differences in regulatory approvals among these parts?

A: Yes. 0215005.MXF162SPP includes CE, CQC, CSA, KC, PSE, UR, and VDE approvals. 0215005.MXF34P includes CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE approvals. Selection should align with the specific regulatory requirements of your application region.

Q: Do all parts meet RoHS compliance?

A: Yes. All four parts are ROHS3 Compliant and REACH Unaffected, meeting environmental and hazardous substance restrictions.

Q: What is the significance of the DC Cold Resistance specification?

A: DC Cold Resistance (0.0153 Ohms) is a measured electrical property of the fuse element at room temperature. Identical values across all substitute parts confirm electrical equivalence and ensure consistent circuit behavior.
