Key Parameters

Substitute Part Grouping Explanation

The KLKD006.T from Littelfuse qualifies as a direct substitute for the KLM-6 based on the following critical parameters:

• Current Rating: 6A (identical)
• Voltage Rating: 600 VAC / 600 VDC (identical)
• Response Time: Fast Blow (identical)
• Fuse Type: Cartridge (identical)
• Mounting Type: Requires Holder (identical)
• Breaking Capacity: 100kA AC / 50kA DC (identical)
• Physical Dimensions: 0.406" Dia x 1.500" L (identical)
• Approval Agencies: CE, CSA, UL (all required certifications present; KLKD006.T includes additional VDE certification)
• RoHS Compliance: ROHS3 Compliant (identical)

All electrical and mechanical parameters align within the specifications required for direct substitution in holder-mounted applications.

Parameter Comparison

Engineering Selection Recommendations

Both the KLM-6 and KLKD006.T maintain active product status and carry identical core electrical and mechanical specifications. Selection between these parts should be based on:

• Availability: KLM-6 has 844 units in stock; KLKD006.T has 1121 units in stock
• Certification Requirements: KLKD006.T includes VDE certification in addition to CE, CSA, and UL
• Supply Chain Considerations: Either part is suitable for direct substitution in holder-mounted 6A 600VAC/VDC fast-blow fuse applications

Both parts comply with ROHS3 and REACH requirements and carry identical breaking capacity ratings.

Frequently Asked Questions (FAQ)

Q: Can KLKD006.T be used as a direct replacement for KLM-6?

A: Yes. Both parts share identical current rating (6A), voltage rating (600 VAC/VDC), response time (fast blow), breaking capacity (100kA AC / 50kA DC), and physical dimensions (0.406" Dia x 1.500" L). Both require holder mounting and carry CE, CSA, and UL certifications.

Q: Are there physical compatibility concerns when substituting between these parts?

A: No. Both parts use the same 5AG cartridge form factor with dimensions of 0.406" Dia x 1.500" L (10.30mm x 38.10mm and 10.31mm x 38.10mm respectively). They are mechanically compatible with the same holder assemblies.

Q: What is the difference in approval certifications?

A: KLM-6 carries CE, CSA, and UL certifications. KLKD006.T carries CE, CSA, UL, and VDE certifications. The additional VDE certification on KLKD006.T does not restrict its use in applications requiring only CE, CSA, and UL.

Q: Do these parts have different electrical characteristics?

A: Both parts are rated for identical voltage (600 VAC/600 VDC), current (6A), and breaking capacity (100kA AC / 50kA DC). KLKD006.T provides additional electrical data including melting I²t (62.951) and DC cold resistance (0.0261 Ohms), but these do not affect substitution compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both KLM-6 and KLKD006.T are ROHS3 compliant and REACH unaffected.
