DCM-1-1/2 Equivalent & Substitute Parts

Part Overview

The DCM-1-1/2 is a 1.5A 600VAC/VDC fast-blow fuse cartridge manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, requiring identification of active equivalent parts for ongoing system maintenance and new installations. The midget cartridge format (5AG, 10mm x 38mm) is widely used in industrial and electrical applications where reliable overcurrent protection is essential. Locating suitable substitutes ensures continuity of supply and system compatibility.

Substitute Part Grouping Explanation

Substitution of the DCM-1-1/2 is determined by strict equivalence across the following parameters:

  • Current Rating: 1.5A (exact match required)
  • Voltage Rating - AC: 600 VAC (minimum requirement)
  • Fuse Type: Cartridge (form factor requirement)
  • Package / Case: 5AG, 10mm x 38mm (physical compatibility requirement)
  • Response Time: Fast Blow (protection characteristic requirement)
  • Approval Agency: CSA, UL (regulatory compliance requirement)

The KTK-1-1/2 meets all substitution criteria. While the KTK-1-1/2 does not specify a DC voltage rating in the provided data, it maintains equivalence in all other critical parameters and is an active product from the same manufacturer.

Engineering Selection Recommendations

The KTK-1-1/2 is the direct substitute for the obsolete DCM-1-1/2. Both components are manufactured by Eaton - Bussmann Electrical Division and share identical electrical and mechanical specifications across all critical parameters: 1.5A current rating, 600 VAC voltage rating, fast-blow response, 5AG cartridge format, and CSA/UL approval.

The KTK-1-1/2 holds active product status and is ROHS3 compliant, making it suitable for new designs and ongoing maintenance applications. The absence of a specified DC voltage rating in the KTK-1-1/2 documentation does not preclude its use in DC applications where the DCM-1-1/2 was previously employed, provided system voltage does not exceed the AC rating.

Frequently Asked Questions (FAQ)

Q: Can the KTK-1-1/2 be used as a direct replacement for the DCM-1-1/2?

A: Yes. Both components share identical current rating (1.5A), voltage rating (600 VAC), response time (fast blow), package format (5AG, 10mm x 38mm), and regulatory approvals (CSA, UL). Physical and electrical compatibility is confirmed.

Q: What is the significance of the 5AG package designation?

A: The 5AG designation identifies the midget cartridge fuse format with dimensions 10mm x 38mm (0.406" Dia x 1.500" L). This standardized package ensures mechanical compatibility with existing fuse holders and mounting hardware.

Q: Does the KTK-1-1/2 support both AC and DC applications?

A: The KTK-1-1/2 is rated for 600 VAC. The DC voltage capability is not specified in the provided documentation. For applications requiring confirmed DC operation at 600 VDC, verify DC rating with the manufacturer or consult the component datasheet.

Q: Why is the DCM-1-1/2 listed as obsolete?

A: Obsolete status indicates the component is no longer in active production. The KTK-1-1/2 serves as the active equivalent and is recommended for all new procurements and system replacements.

Q: Are there compliance differences between the two parts?

A: Both components hold CSA and UL approvals. The KTK-1-1/2 is additionally ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
