Littelfuse 0460005.ER Surface Mount Board Mount Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0460005.ER is a 5A 125VAC/VDC surface mount board mount fuse in the PICO® 460 series. This slow blow fuse is designed for circuit protection in applications requiring reliable overcurrent protection with a 50A breaking capacity at rated voltage. The part is actively manufactured and widely stocked, with 1108 units available in inventory. Substitute parts are identified to provide alternative sourcing options while maintaining identical electrical and mechanical specifications for direct board-level replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0460005.ER are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria include:

• Current Rating: 5 A (exact match required)
• Voltage Rating: 125 V AC / 125 V DC (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 2-SMD, J-Lead (exact match required)
• Breaking Capacity @ Rated Voltage: 50 A (exact match required)
• Melting I²t: 54.8 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• DC Cold Resistance: 0.0133 Ohms (exact match required)
• Approval Agencies: CSA, PSE, UL (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part 0460005.UR meets all these criteria and is therefore a direct parametric equivalent suitable for board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

Both the 0460005.ER and 0460005.UR are active products manufactured by Littelfuse Inc. and carry identical certifications from CSA, PSE, and UL. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

The 0460005.UR offers higher inventory availability with 3809 units in stock compared to 1108 units for the 0460005.ER. Both parts are supplied in Tape & Reel packaging and are suitable for automated assembly processes.

Selection between these parts should be based on supply chain availability and lead time requirements, as they are parametrically identical and interchangeable at the board level.

Frequently Asked Questions (FAQ)

Q: Can the 0460005.UR be used as a direct replacement for the 0460005.ER?

A: Yes. The 0460005.UR is a parametric equivalent with identical electrical ratings (5A, 125VAC/VDC), response time (Slow Blow), breaking capacity (50A), melting I²t (54.8), operating temperature range (-55°C ~ 125°C), DC cold resistance (0.0133 Ohms), and package configuration (2-SMD, J-Lead). Both parts meet the same regulatory certifications and are suitable for direct board-level substitution.

Q: Are there any differences in the physical package between these parts?

A: No. Both parts share identical dimensions of 0.285" L x 0.170" W x 0.120" H (7.24mm x 4.32mm x 3.05mm) and use the same 2-SMD, J-Lead package configuration. They are mechanically interchangeable on PCB layouts designed for either part number.

Q: What is the difference between the .ER and .UR suffix designations?

A: The suffix designations indicate different packaging or distribution channels from Littelfuse Inc. Both parts are from the PICO® 460 series and meet identical electrical and mechanical specifications. The difference is not reflected in the technical parameters provided.

Q: Are both parts suitable for automated assembly?

A: Yes. Both the 0460005.ER and 0460005.UR are supplied in Tape & Reel (TR) packaging, which is standard for surface mount automated assembly processes.

Q: What certifications do these fuses carry?

A: Both parts carry certifications from CSA, PSE, and UL, meeting international safety and performance standards for circuit protection devices.

Q: Are these parts RoHS compliant?

A: Yes. Both the 0460005.ER and 0460005.UR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
