Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0230.600DRT2W are selected based on strict electrical and mechanical parameter matching within the Littelfuse 230 series. The primary substitution criteria are:

Core Matching Parameters:

• Current Rating: 600 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.177" Dia x 0.571" L (4.50mm x 14.50mm) (exact match required)
• Melting I²t: 1.75 (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Secondary Considerations:

• Voltage Rating (DC): The main part has no DC rating specified; substitute parts with 125 V DC rating provide enhanced capability without compromising AC performance
• Breaking Capacity: Substitute parts rated at 35A AC and 10kA DC exceed the main part's 35A specification, providing improved fault protection
• DC Cold Resistance: Substitute parts at 0.4805 Ohms are within acceptable tolerance of the main part's 0.477 Ohms
• RoHS Compliance: Substitute parts are ROHS3 compliant, addressing modern environmental standards
• Approval Agencies: Substitute parts carry CE, CSA, and UL certifications, expanding regulatory coverage

All substitute parts maintain identical form factor, electrical performance under rated AC conditions, and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components from Littelfuse Inc. within the 230 series, providing direct electrical and mechanical equivalence to the obsolete 0230.600DRT2W.

For AC-only applications: Any substitute part maintains identical AC performance at 250 V and 600 mA with slow-blow response characteristics. The 0230.600DRT2P, 0230.600DRT1P, 0230.600DRT1SP, 0230.600DRT2SP, 0230.600DRT3P, 0230.600DRT3SP, and 0230.600MRT1SSP are functionally equivalent for circuits operating exclusively on AC power.

For applications requiring DC capability: All substitute parts include 125 V DC rating, providing enhanced circuit protection in mixed AC/DC environments without affecting AC performance.

For regulatory compliance: Substitute parts carry CE certification in addition to CSA and UL approvals, meeting expanded international standards. All substitute parts are ROHS3 compliant, addressing environmental and material restriction requirements.

For high-volume procurement: Substitute parts are available in Tape & Reel packaging, supporting automated assembly processes. Inventory levels range from 666 to 1117 pieces, ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the 0230.600DRT2W be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts maintain identical current rating (600 mA), AC voltage rating (250 V), fuse type (cartridge, glass), response time (slow blow), physical dimensions (0.177" Dia x 0.571" L), and thermal operating range (-55°C ~ 125°C). Direct substitution is supported for through-hole axial mounting applications.

Q: What is the difference between the main part and substitute parts?

A: The primary differences are product status and compliance. The 0230.600DRT2W is obsolete and RoHS non-compliant. All substitute parts are active production items with ROHS3 compliance and CE certification. Substitute parts also include 125 V DC rating and 10kA DC breaking capacity, providing enhanced protection without affecting AC operation.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The main part packaging is not specified. All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly. For manual assembly or through-hole insertion applications, TR packaging can be manually dispensed.

Q: Do all substitute parts have identical electrical characteristics?

A: Yes, for AC operation at rated conditions. All substitute parts share the same 600 mA current rating, 250 V AC voltage rating, 1.75 melting I²t, and -55°C ~ 125°C operating temperature range. DC cold resistance values are within acceptable tolerance (0.4805 Ohms vs. 0.477 Ohms).

Q: Which substitute part should be selected for new designs?

A: All substitute parts are functionally equivalent. Selection may be based on inventory availability, packaging preference, or specific procurement requirements. The 0230.600DRT3P and 0230.600DRT3SP offer the highest inventory levels (1117 and 994 pieces respectively).

Q: Are the substitute parts certified for the same applications?

A: Substitute parts carry CSA and UL certifications matching the main part, with the addition of CE certification. All substitute parts meet the same approval standards for electrical safety and performance.
