Littelfuse 0263002.MAT1L Board Mount Fuse - Equivalent & Substitute Parts

Part Overview

The Littelfuse 0263002.MAT1L is a 2A 250VAC board mount fuse in axial package configuration, designed for through-hole PCB mounting applications. This PICO® II 263 series fuse operates with fast-blow response characteristics and is rated for breaking capacity of 50A at rated voltage. The part maintains active product status with full compliance to CSA, PSE, and UR approval agencies. Substitute parts are identified when identical electrical ratings, mechanical dimensions, and approval certifications are maintained across alternative part numbers within the same manufacturer product line.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 0263002.HAT1L qualifies as a parametric equivalent based on the following critical substitution criteria:

• Current Rating: Identical at 2 A
• Voltage Rating (AC): Identical at 250 V
• Response Time: Identical fast-blow characteristic
• Mounting Type: Identical through-hole configuration
• Package / Case: Identical axial package
• Breaking Capacity: Identical at 50 A
• Melting I²t: Identical at 0.74
• Operating Temperature Range: Identical -55°C to 125°C
• Physical Dimensions: Identical 0.155" Dia x 0.280" L (3.94mm x 7.11mm)
• Approval Agencies: Identical CSA, PSE, UR certifications
• RoHS Compliance: Identical ROHS3 Compliant status

Both parts belong to the PICO® II 263 series and maintain identical electrical and mechanical specifications. The substitution is valid for direct replacement in circuit applications where the main part number is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the 0263002.MAT1L and 0263002.HAT1L maintain active product status within the Littelfuse PICO® II 263 series. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical performance differences. Both parts carry identical regulatory approvals (CSA, PSE, UR) and maintain ROHS3 compliance with REACH unaffected status, ensuring equivalent compliance posture for end-use applications. The 0263002.MAT1L currently maintains higher inventory levels (1636 Pcs) compared to the substitute (1189 Pcs), which may influence procurement decisions based on lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can 0263002.HAT1L be used as a direct replacement for 0263002.MAT1L?

A: Yes. Both parts are parametric equivalents with identical current rating (2A), voltage rating (250VAC), response time (fast-blow), breaking capacity (50A), physical dimensions (0.155" Dia x 0.280" L), and all regulatory approvals. Direct substitution is valid for through-hole PCB mounting applications.

Q: Are there any differences in electrical performance between these two part numbers?

A: No. Both parts share identical electrical specifications including current rating, voltage rating, melting I²t value (0.74), and breaking capacity. The DC cold resistance specification is provided for the substitute part but does not affect substitution validity.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both 0263002.MAT1L and 0263002.HAT1L carry identical approvals from CSA, PSE, and UR agencies. Both are ROHS3 compliant and REACH unaffected, ensuring equivalent compliance for regulated applications.

Q: What is the difference between the MAT1L and HAT1L designations?

A: The designations reflect different packaging tape configurations (Cut Tape) within the same electrical and mechanical specification set. Both maintain identical performance characteristics for circuit protection applications.

Q: Can these parts be used in applications requiring -55°C to 125°C operation?

A: Yes. Both parts are rated for the full -55°C to 125°C operating temperature range and maintain their specified electrical characteristics across this temperature span.
