Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 02153.15MXF151SPP are qualified based on the following critical parameters that must match exactly:

• Current Rating: 3.15 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Slow Blow
• Mounting Type: Through Hole
• Package / Case: Radial Bend Cylinder
• Size / Dimension: 0.205" Dia x 0.787" L (5.20mm x 20.00mm)
• Breaking Capacity @ Rated Voltage: 1.5 kA
• Melting I²t: 43.255
• DC Cold Resistance: 0.0283 Ohms
• Operating Temperature Range: -55°C ~ 125°C

All identified substitute parts maintain identical electrical performance characteristics and mechanical compatibility. Variations in series designation (215 vs. 215SP) and approval agency certifications do not affect functional equivalence for circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All five parts listed—02153.15MXF151SPP, 02153.15MXF11P, 02153.15MXF163SPP, 02153.15MXF34P, and 02153.15MXF51P—are functionally equivalent for circuit protection applications requiring 3.15 A, 250 V AC/DC ceramic cartridge fuses with slow-blow response characteristics.

Selection between these parts may be based on:

• Approval agency certifications: 02153.15MXF51P carries the broadest certification scope (BSI, CCC, CE, CSA, KC, PSE, SEMKO, UR, VDE), while 02153.15MXF151SPP and 02153.15MXF163SPP include CQC and UR certifications. 02153.15MXF11P and 02153.15MXF34P include CCC, SEMKO, and UL certifications.
• Inventory availability: 02153.15MXF11P offers the highest stock level at 6200 units, followed by 02153.15MXF163SPP at 2818 units.
• Series designation: 215SP series (02153.15MXF151SPP, 02153.15MXF163SPP) versus 215 series (02153.15MXF11P, 02153.15MXF34P, 02153.15MXF51P).

All parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics.

Frequently Asked Questions (FAQ)

Q: Can 02153.15MXF11P be used as a direct replacement for 02153.15MXF151SPP?

A: Yes. Both parts share identical current rating (3.15 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), mounting configuration (through hole), physical dimensions (0.205" Dia x 0.787" L), breaking capacity (1.5 kA), melting I²t (43.255), and operating temperature range (-55°C ~ 125°C). The series designation difference (215 vs. 215SP) does not affect functional equivalence.

Q: What is the difference between 02153.15MXF163SPP and 02153.15MXF151SPP?

A: These parts are electrically and mechanically identical. Both belong to the 215SP series and carry the same electrical specifications. The primary difference is inventory availability (2818 units for 02153.15MXF163SPP versus 806 units for 02153.15MXF151SPP) and approval agency certifications, which do not affect circuit protection performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All five parts listed—02153.15MXF151SPP, 02153.15MXF11P, 02153.15MXF163SPP, 02153.15MXF34P, and 02153.15MXF51P—are ROHS3 compliant and maintain identical environmental compliance status.

Q: Which substitute part has the best availability?

A: 02153.15MXF11P offers the highest inventory level at 6200 units in stock, making it the most readily available equivalent for immediate procurement.

Q: Do approval agency certifications affect substitution compatibility?

A: Approval agency certifications do not affect electrical or mechanical compatibility between these parts. Certification differences reflect regional regulatory requirements and manufacturing process variations but do not impact circuit protection performance. Selection based on certifications should align with end-application regulatory requirements.

Q: Can these fuses be used interchangeably in the same circuit board layout?

A: Yes. All substitute parts maintain identical physical dimensions (0.205" Dia x 0.787" L / 5.20mm x 20.00mm) and radial bend cylinder package configuration, ensuring mechanical compatibility with existing through-hole mounting footprints.
