Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0215010.MXF46P is determined by strict equivalence across the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial Bend Cylinder (exact match required)
• Size / Dimension: 0.205" Dia x 0.787" L (5.20mm x 20.00mm) (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Melting I²t: 334.665 (exact match required)
• DC Cold Resistance: 0.0066 Ohms (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All four substitute parts listed below meet these criteria and are therefore direct parametric equivalents suitable for interchangeable use in applications requiring the 0215010.MXF46P.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P, 0215010.MXF56P) are direct parametric equivalents to the 0215010.MXF46P and maintain identical electrical and mechanical specifications. Selection among these parts may be based on the following factors:

Approval Agency Coverage: The 0215010.MXF46P carries approvals from BSI, CE, CQC, KC, PSE, SEMKO, UR, and VDE. The 0215010.MXF11P includes CE, CSA, KC, PSE, SEMKO, UL, and VDE. The 0215010.MXF20P and 0215010.MXF34P both include BSI, CE, CSA, KC, METI, SEMKO, UL, and VDE. The 0215010.MXF56P matches the original with BSI, CE, CQC, KC, PSE, SEMKO, UR, and VDE. Selection should align with regional regulatory requirements and end-application certifications.

Inventory Availability: The 0215010.MXF11P offers the highest inventory level at 6300 units, followed by 0215010.MXF20P (1998 units), 0215010.MXF56P (2268 units), and 0215010.MXF34P (1588 units). The original 0215010.MXF46P maintains 726 units in stock.

Regional Compliance: Parts with UL certification (0215010.MXF11P, 0215010.MXF20P, 0215010.MXF34P) are suitable for North American applications. Parts with UR certification (0215010.MXF46P, 0215010.MXF56P) support additional regional requirements.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts truly interchangeable with the 0215010.MXF46P?

A: Yes. All substitute parts meet identical specifications across current rating, voltage rating, response time, fuse type, mounting configuration, physical dimensions, breaking capacity, melting I²t, DC cold resistance, operating temperature range, and RoHS compliance status. They are direct parametric equivalents suitable for interchangeable use.

Q: What determines whether a part can substitute for the 0215010.MXF46P?

A: Substitution requires exact equivalence across all critical parameters: 10 A current rating, 250 V AC voltage rating, slow-blow response, ceramic cartridge type, through-hole mounting, radial bend cylinder package, 5.20mm x 20.00mm dimensions, 1.5 kA breaking capacity, 334.665 melting I²t, 0.0066 Ohms DC cold resistance, -55°C to 125°C operating range, and ROHS3 compliance.

Q: Do the substitute parts have different approval certifications?

A: Yes. While all parts are ROHS3 compliant and carry multiple regional approvals, the specific certification agencies vary. The 0215010.MXF46P and 0215010.MXF56P include CQC, PSE, and UR certifications. The 0215010.MXF11P, 0215010.MXF20P, and 0215010.MXF34P include CSA and UL certifications. Selection should match the regulatory requirements of the target application and region.

Q: Can I use a substitute part if my application requires a specific certification?

A: Verify that the substitute part carries the required certification for your application. Consult the approval agency list for each part number to confirm compliance with regional standards and end-product certification requirements.

Q: Are there inventory differences among the substitute parts?

A: Yes. Inventory levels vary: 0215010.MXF11P (6300 units), 0215010.MXF20P (1998 units), 0215010.MXF56P (2268 units), 0215010.MXF34P (1588 units), and 0215010.MXF46P (726 units). Higher inventory availability may support shorter lead times for procurement.

Q: What is the physical package compatibility for these fuses?

A: All parts use identical radial bend cylinder packaging with 0.205" diameter and 0.787" length (5.20mm x 20.00mm). They are mechanically compatible with through-hole PCB footprints designed for the 0215010.MXF46P.
