Key Parameters

Substitute Part Grouping Explanation

The substitute part 0473007.MAT1L is classified as a parametric equivalent based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

• Current rating: 7 A (exact match)
• Voltage rating: 125 V AC and 125 V DC (exact match)
• Response time: Slow Blow (exact match)
• Mounting type: Through Hole (exact match)
• Package type: Axial (exact match)
• Physical dimensions: 0.135" Dia x 0.280" L (exact match)
• Breaking capacity: 50 A (exact match)
• Thermal characteristics: -55°C ~ 125°C operating range (exact match)
• Regulatory compliance: CSA and UR approvals (exact match)
• Environmental compliance: ROHS3 and REACH Unaffected (exact match)

The only difference between the main part and substitute is the packaging format: Tape & Box (TB) versus Cut Tape (CT). Both packaging types contain identical components suitable for automated or manual assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the main part 0473007.MAT1JL and substitute 0473007.MAT1L are active products from Littelfuse with identical electrical performance and regulatory compliance. Selection between these parts should be based on packaging requirements and supply availability:

• 0473007.MAT1JL (Tape & Box): Suitable for mixed-volume production runs and manual assembly processes where component accessibility is prioritized.
• 0473007.MAT1L (Cut Tape): Optimized for high-volume automated assembly operations using tape-fed pick-and-place equipment.

Both parts maintain CSA and UR certifications, ROHS3 compliance, and REACH Unaffected status. No functional or performance differences exist between the two variants.

Frequently Asked Questions (FAQ)

Q: Can 0473007.MAT1L be used as a direct replacement for 0473007.MAT1JL?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Box). Direct substitution is valid for any application using the main part.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging includes a full reel of components in a protective box, suitable for manual assembly and mixed-volume applications. Cut Tape packaging provides components on tape segments, optimized for automated pick-and-place assembly systems. Both contain identical components.

Q: Are both parts certified by the same regulatory agencies?

A: Yes. Both 0473007.MAT1JL and 0473007.MAT1L carry CSA and UR approvals and meet ROHS3 compliance requirements.

Q: What is the melting I²t value, and why is it important?

A: The melting I²t value of 105 indicates the thermal energy required to melt the fuse element. This parameter ensures consistent protection characteristics and is identical between both parts.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. Both parts are rated for 125 V AC and 125 V DC operation, making them suitable for dual-voltage applications.

Q: What is the breaking capacity specification?

A: The breaking capacity of 50 A at rated voltage indicates the maximum fault current the fuse can safely interrupt without damage or hazard.
