Littelfuse 0230006.DRT2SW Glass Axial Fuse 6A 125VAC Equivalent & Substitute Parts

Part Overview

The Littelfuse 0230006.DRT2SW is a 6 A, 125 V AC DC glass cartridge fuse with axial through-hole mounting. This component is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing design and procurement requirements. The part operates across a temperature range of -55°C to 125°C with a slow-blow response characteristic and 400 A breaking capacity at rated voltage. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0230006.DRT2SW is based on strict electrical and mechanical parameter matching within the Littelfuse 230 series. All identified substitute parts maintain the following critical parameters:

• Current Rating: 6 A
• Voltage Rating (AC): 125 V
• Voltage Rating (DC): 125 V (substitute parts explicitly rated for DC operation)
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Mounting Type: Through Hole
• Package / Case: Cartridge, Non-Standard (Axial)
• Size / Dimension: 0.177" Dia x 0.571" L (4.50mm x 14.50mm)
• Breaking Capacity @ Rated Voltage: 400 A
• Melting I²t: 380
• Operating Temperature Range: -55°C ~ 125°C
• Series: 230

The primary distinction between the main part and substitutes is product status (obsolete versus active) and packaging configuration (bulk versus tape & reel). All substitute parts are active products with enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All seven substitute parts are direct functional equivalents of the 0230006.DRT2SW. Selection among these alternatives is determined by procurement and assembly requirements rather than electrical performance differences.

For applications requiring bulk packaging, no active equivalent exists; however, tape & reel packaged alternatives are available for automated assembly processes. All substitute parts carry active product status and ROHS3 compliance, addressing regulatory requirements that the obsolete main part does not meet. Certification coverage across all substitutes includes CE, CSA, PSE, and UL approvals, providing broader international compliance than the main part's cUL and METI certifications.

DC cold resistance values for all substitute parts are 0.0141 Ohms, representing a marginal increase from the main part's 0.014 Ohms. This difference is within normal manufacturing tolerance and does not affect circuit performance.

Frequently Asked Questions (FAQ)

Q: Can 0230006.DRT2SW be directly replaced with any of the listed substitutes?

A: Yes. All substitute parts maintain identical electrical ratings (6 A, 125 V AC/DC), response characteristics (slow-blow), mechanical dimensions (0.177" Dia x 0.571" L), and breaking capacity (400 A). Physical form factor and mounting method are identical.

Q: What is the difference between the main part and substitutes?

A: The primary differences are product status (obsolete versus active) and packaging format. The main part is supplied in bulk; all substitutes are supplied in tape & reel format. Substitute parts also carry enhanced compliance certifications (ROHS3, CE, CSA, PSE, UL) compared to the main part (cUL, METI).

Q: Are there packaging considerations for assembly?

A: Yes. The main part's bulk packaging is suitable for manual assembly or pick-and-place operations without tape & reel compatibility. All substitute parts are supplied in tape & reel format, which requires compatible automated assembly equipment. Manual assembly of tape & reel packaged parts is possible but requires manual extraction from the carrier tape.

Q: Does the slight increase in DC cold resistance affect circuit operation?

A: No. The increase from 0.014 Ohms to 0.0141 Ohms is negligible and falls within normal manufacturing tolerance for this component category. Circuit performance and thermal characteristics remain unchanged.

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

A: Any of the seven substitute parts is electrically and mechanically equivalent. Selection should be based on packaging requirements (tape & reel format for all substitutes) and internal procurement availability. All parts carry identical electrical specifications and certifications.

Q: Are all substitutes available in the same quantity?

A: Inventory levels vary across the substitute parts, ranging from 703 to 1182 pieces. Procurement should verify current availability with the supplier for the selected part number.
