Substitute Part Grouping Explanation

The 047301.5YAT1L and 047301.5MAT1L are parametric equivalents within the PICO® II 473 series. Substitution is valid based on the following criteria:

Identical Electrical Parameters:

• Current Rating: 1.5 A
• Voltage Rating: 125 V AC / 125 V DC
• Response Time: Slow Blow
• Breaking Capacity: 50 A @ Rated Voltage
• Melting I²t: 3.94
• DC Cold Resistance: 0.116 Ohms

Identical Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: Axial
• Size / Dimension: 0.135" Dia x 0.280" L (3.43mm x 7.11mm)

Identical Compliance & Certifications:

• Approval Agencies: CSA, PSE, UR
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Operating Temperature: -55°C to 125°C

Difference:

• Packaging format only: Tape & Box (TB) versus Cut Tape (CT)

Both parts are active products from the same manufacturer and series, differing only in supply packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Both 047301.5YAT1L and 047301.5MAT1L are active products from Littelfuse Inc. with identical electrical, mechanical, and compliance specifications. Selection between these parts should be based on packaging requirements and inventory availability:

047301.5YAT1L (Tape & Box): Suitable for applications requiring boxed packaging with tape format. Current inventory: 1175 pieces.

047301.5MAT1L (Cut Tape): Suitable for applications requiring cut tape format. Current inventory: 1929 pieces.

Both parts carry identical certifications (CSA, PSE, UR) and meet ROHS3 compliance requirements. Either part is functionally and mechanically interchangeable in through-hole PCB applications requiring 1.5 A slow blow fuse protection at 125 V AC/DC.

Frequently Asked Questions (FAQ)

Q: Can 047301.5MAT1L replace 047301.5YAT1L in my circuit design?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (1.5 A, 125 V AC/DC), response characteristics (slow blow), mechanical dimensions (0.135" Dia x 0.280" L), and certifications. The only difference is packaging format (Cut Tape versus Tape & Box).

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

A: Tape & Box packaging includes a protective box containing the taped components, suitable for standard component storage and handling. Cut Tape packaging provides individual components on tape without the box, typically used for automated assembly or bulk component distribution. Both formats contain identical parts.

Q: Are the electrical characteristics identical between these substitutes?

A: Yes. Both parts share identical current rating (1.5 A), voltage rating (125 V AC/125 V DC), response time (slow blow), breaking capacity (50 A), melting I²t (3.94), and DC cold resistance (0.116 Ohms).

Q: Do both parts meet the same compliance standards?

A: Yes. Both 047301.5YAT1L and 047301.5MAT1L carry identical approvals from CSA, PSE, and UR, and both are ROHS3 compliant and REACH unaffected.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts have identical through-hole mounting specifications and axial package dimensions (0.135" Dia x 0.280" L / 3.43mm x 7.11mm), making them mechanically and electrically interchangeable in board-level applications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C.
