DCM-1/10 Equivalent & Substitute Parts

Part Overview

The DCM-1/10 is a 100mA fast-blow fuse cartridge rated for 600 VAC and 600 VDC operation, manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, though 873 pieces remain in stock. The DCM-1/10 is designed for electrical and industrial applications requiring cartridge-style fuse protection in a 5AG, 10mm x 38mm (Midget) package format. Due to its obsolete status, equivalent substitute parts with active product status are available to ensure supply chain continuity and long-term component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DCM-1/10 are qualified based on the following critical parameters that must remain constant:

• Current Rating: 100mA (exact match required)
• Fuse Type: Cartridge (exact match required)
• Package / Case: 5AG, 10mm x 38mm (Midget) (exact match required)
• Size / Dimension: 0.406" Dia x 1.500" L (exact match required)
• Response Time: Fast Blow (exact match required)
• Voltage Rating - AC: 600 VAC (exact match required)
• Mounting Type: Requires Holder (exact match required)

The substitute parts identified below meet all critical electrical and mechanical parameters. Variations in DC voltage rating and compliance certifications are noted where applicable, as these represent enhancements or regional compliance differences rather than functional incompatibilities.

Engineering Selection Recommendations

KTK-1/10 (Eaton - Bussmann Electrical Division)

The KTK-1/10 is the primary substitute for the DCM-1/10. Both components are manufactured by Eaton - Bussmann Electrical Division and share identical electrical and mechanical specifications. The KTK-1/10 maintains active product status with 811 pieces in stock, ensuring supply chain availability. This part carries CSA and UL approvals matching the original specification. Selection of the KTK-1/10 eliminates obsolescence risk while maintaining full functional equivalence.

0KLK.100T (Littelfuse Inc. POWR-GARD® KLK Series)

The 0KLK.100T is a secondary substitute manufactured by Littelfuse Inc. This component meets all critical electrical and mechanical parameters with identical current rating, AC voltage rating, fuse type, response time, and package dimensions. The DC voltage rating is specified at 500 VDC compared to the original 600 VDC specification. The 0KLK.100T carries expanded regulatory approvals including CE, CSA, QPL, and UL certifications. This part is suitable for applications where the 500 VDC rating is acceptable and where Littelfuse component qualification is required. Active product status with 751 pieces in stock ensures availability.

Frequently Asked Questions (FAQ)

Q: Can the KTK-1/10 be used as a direct replacement for the DCM-1/10?

A: Yes. The KTK-1/10 is a direct functional equivalent. Both parts share identical current rating (100mA), AC voltage rating (600 VAC), fuse type (Cartridge), response time (Fast Blow), package format (5AG, 10mm x 38mm Midget), and physical dimensions. Both carry CSA and UL approvals. The KTK-1/10 is manufactured by the same company (Eaton - Bussmann Electrical Division) and maintains active product status.

Q: What is the difference between the DCM-1/10 and the 0KLK.100T?

A: The primary difference is the DC voltage rating. The DCM-1/10 is rated for 600 VDC, while the 0KLK.100T is rated for 500 VDC. All other electrical parameters (100mA current, 600 VAC AC rating, Fast Blow response) and mechanical parameters (5AG package, 10mm x 38mm dimensions) are identical. The 0KLK.100T is manufactured by Littelfuse Inc. and carries additional CE and QPL certifications.

Q: Is the 0KLK.100T suitable for applications requiring 600 VDC operation?

A: The 0KLK.100T is rated for 500 VDC maximum. Applications requiring 600 VDC operation should use the DCM-1/10 or KTK-1/10. The 0KLK.100T is suitable only for applications where the operating DC voltage does not exceed 500 VDC.

Q: Are all substitute parts compatible with the same fuse holder?

A: Yes. All substitute parts use the 5AG, 10mm x 38mm (Midget) package format and require a holder. Physical dimensions are identical or equivalent (0.406" Dia x 1.500" L), ensuring compatibility with existing fuse holders designed for the DCM-1/10.

Q: What is the difference in product status between these parts?

A: The DCM-1/10 is classified as obsolete, indicating it is no longer in active production. The KTK-1/10 and 0KLK.100T both maintain active product status, meaning they are currently manufactured and supported by their respective suppliers. Active status ensures long-term availability and supply chain continuity.

Q: Which substitute should be selected for new designs?

A: For new designs, either the KTK-1/10 or 0KLK.100T is appropriate. The KTK-1/10 is recommended if 600 VDC operation is required or if component continuity with Eaton - Bussmann Electrical Division is preferred. The 0KLK.100T is suitable if 500 VDC operation meets application requirements and if Littelfuse component qualification is specified.
