Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0469006.WR is determined by strict equivalence across the following critical parameters:

• Current Rating: 6 A (exact match required)
• Voltage Rating (DC): 24 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)

The substitute part 0407006.WR meets all these critical parameters and is therefore electrically and mechanically interchangeable with the 0469006.WR.

Parameter Comparison

Engineering Selection Recommendations

The 0407006.WR is the direct substitute for the obsolete 0469006.WR. Both parts are manufactured by Littelfuse Inc. and share identical electrical and mechanical specifications across all critical parameters. The 0407006.WR carries Active product status, ensuring long-term availability and supply chain continuity.

The 0407006.WR holds cURus certification (Canadian and UL approval), while the original part holds CSA and UL certification. Both certifications are recognized for North American applications. The substitute part is available in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 0407006.WR be used as a direct replacement for the 0469006.WR?

A: Yes. Both parts are identical in current rating (6 A), voltage rating (24 V DC), response time (Slow Blow), package format (1206 / 3216 Metric), and mounting type (Surface Mount). They are electrically and mechanically interchangeable.

Q: What is the difference between the two parts?

A: The primary differences are product status (0469006.WR is Obsolete; 0407006.WR is Active) and packaging format (0469006.WR is standard packaging; 0407006.WR is Tape & Reel). The substitute part also has different DC cold resistance (0.012 Ohms vs. 0.028 Ohms) and melting I²t values (15.56 vs. 9.41), but these variations remain within acceptable substitution parameters for this fuse category.

Q: Are there any certification differences?

A: The original part carries CSA and UL approvals. The substitute part carries cURus certification (which includes both Canadian and UL approval). Both certifications are valid for North American industrial and commercial applications.

Q: What packaging options are available for the substitute part?

A: The 0407006.WR is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. This format is compatible with pick-and-place equipment used in modern PCB manufacturing.

Q: Is the 0407006.WR RoHS compliant?

A: Yes. The 0407006.WR is ROHS3 compliant, matching the compliance status of the original 0469006.WR.
