DCM-5 Equivalent & Substitute Parts

Part Overview

The DCM-5 is a 5A cartridge fuse rated for 600 VAC/VDC operation, manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, though 863 pieces remain available in new original stock. The DCM-5 is designed for electrical and industrial applications requiring fast-blow fuse protection in holder-mounted configurations. Due to its obsolete status, identifying active equivalent parts ensures continued availability and supply chain reliability for new designs and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DCM-5 is based on strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 5A (exact match required)
• Voltage Rating: 600 VAC and 600 VDC (both must be met)
• Fuse Type: Cartridge with fast-blow response
• Package / Case: 5AG, 10mm x 38mm (Midget) form factor
• Size / Dimension: 0.406" Dia x 1.500" L (10.30mm x 38.10mm)
• Breaking Capacity: 100kA AC, 50kA DC minimum
• Mounting: Holder-mounted configuration

The KLM-5 meets all these criteria and is manufactured by the same supplier (Eaton - Bussmann Electrical Division), ensuring mechanical and electrical compatibility with existing DCM-5 installations.

Parameter Comparison

Engineering Selection Recommendations

The KLM-5 is the direct functional equivalent to the DCM-5. Both components share identical electrical ratings (5A, 600 VAC/VDC), mechanical dimensions (5AG, 10mm x 38mm), and breaking capacity specifications (100kA AC, 50kA DC). The primary distinction is product status: the DCM-5 is obsolete while the KLM-5 is active.

For new designs and ongoing maintenance applications, the KLM-5 is the appropriate selection. It carries expanded regulatory approval (CE, CSA, UL versus CSA, UL for the DCM-5) and maintains RoHS3 compliance. Both components are REACH unaffected and share the same ECCN and HTSUS classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the KLM-5 be used as a direct replacement for the DCM-5?

A: Yes. The KLM-5 meets all electrical and mechanical specifications of the DCM-5, including current rating (5A), voltage rating (600 VAC/VDC), fuse type (cartridge, fast-blow), package designation (5AG), and physical dimensions (0.406" Dia x 1.500" L). Both require holder-mounted installation and deliver identical breaking capacity (100kA AC, 50kA DC).

Q: What is the difference between the DCM-5 and KLM-5?

A: The DCM-5 is obsolete; the KLM-5 is active. The KLM-5 carries additional CE certification and RoHS3 compliance. Functionally and mechanically, they are equivalent.

Q: Are there any compatibility concerns when substituting the KLM-5 for the DCM-5?

A: No. Both components use the same 5AG cartridge form factor and 10mm x 38mm (Midget) package dimensions. They are mechanically and electrically interchangeable in any holder-mounted fuse application rated for 5A, 600 VAC/VDC operation.

Q: Does the KLM-5 meet the same regulatory approvals as the DCM-5?

A: The KLM-5 exceeds the DCM-5 in regulatory coverage. The DCM-5 carries CSA and UL approval; the KLM-5 carries CE, CSA, and UL approval. Both are REACH unaffected and share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications.

Q: What is the inventory status of these parts?

A: The DCM-5 has 863 pieces in new original stock (obsolete status). The KLM-5 has 1011 pieces in new original stock (active status). For long-term supply assurance, the KLM-5 is the recommended choice.
