DCM-10 Equivalent & Substitute Parts Reference

Part Overview

The DCM-10 is a 10A 600VAC/VDC fast-blow fuse cartridge manufactured by Eaton - Bussmann Electrical Division. This component is classified as obsolete, though 1043 pieces remain in stock as new original inventory. The DCM-10 requires a holder for installation and is designed for electrical and industrial applications. Due to its obsolete status, identifying active equivalent and substitute parts is essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DCM-10 is determined by strict alignment across the following critical parameters:

• Current Rating: 10A (exact match required)
• Voltage Rating: 600 VAC minimum; 600 VDC where applicable
• Response Time: Fast Blow (exact match required)
• Fuse Type: Cartridge (exact match required)
• Package / Case: 5AG, 10mm x 38mm (Midget) (exact match required)
• Physical Dimensions: 0.406" Dia x 1.500" L (exact match required)
• Breaking Capacity: 100kA AC minimum; 50kA DC where applicable
• Mounting Type: Requires Holder (exact match required)

Two substitute parts meet these criteria: KTK-10 (Eaton - Bussmann Electrical Division) and KLKD010.T (Littelfuse Inc.). Both are active products with current manufacturing status and full inventory availability.

Parameter Comparison

Engineering Selection Recommendations

KTK-10 and KLKD010.T are both qualified substitutes for the obsolete DCM-10 based on electrical and mechanical parameter alignment.

KTK-10 is manufactured by the same supplier as the original DCM-10 (Eaton - Bussmann Electrical Division) and maintains identical package specifications and dimensional tolerances. This part carries active product status with CSA and UL approvals. The KTK-10 does not specify a DC voltage rating; applications requiring 600 VDC operation should reference the original DCM-10 specification or consult manufacturer documentation.

KLKD010.T is manufactured by Littelfuse Inc. under the POWR-GARD® KLKD series. This part provides full electrical equivalence with 600 VAC and 600 VDC ratings, matching the DCM-10 specification. Physical dimensions are within tolerance (10.31mm vs. 10.30mm diameter). The KLKD010.T carries expanded regulatory approvals including CE and VDE certification in addition to CSA and UL. This part is suitable for applications requiring broader international compliance.

Both substitutes are currently in active production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can KTK-10 be used in applications requiring 600 VDC operation?

A: The KTK-10 specification does not include a DC voltage rating. Applications requiring 600 VDC operation should use KLKD010.T or consult Eaton - Bussmann Electrical Division for DC capability confirmation.

Q: Are the physical dimensions of KLKD010.T compatible with existing DCM-10 holders?

A: KLKD010.T dimensions are 0.406" Dia x 1.500" L (10.31mm x 38.10mm), compared to DCM-10 dimensions of 0.406" Dia x 1.500" L (10.30mm x 38.10mm). The 0.01mm diameter difference is within standard mechanical tolerance for cartridge fuse holders designed for 5AG midget cartridges.

Q: What is the difference between KTK-10 and KLKD010.T packaging?

A: KTK-10 is supplied in bulk packaging. KLKD010.T is supplied in box packaging. Both are new original inventory. Packaging selection depends on procurement and storage requirements.

Q: Which substitute part should be selected for new designs?

A: Selection between KTK-10 and KLKD010.T depends on application requirements. For AC-only applications, KTK-10 provides same-manufacturer continuity. For applications requiring 600 VDC operation or international compliance certifications, KLKD010.T is the appropriate selection.

Q: Are both substitute parts RoHS compliant?

A: KTK-10 is ROHS3 compliant. KLKD010.T is ROHS3 compliant. Both parts meet current RoHS requirements.
