DMT1S15K Equivalent & Substitute Parts Reference

Part Overview

The DMT1S15K is a 0.015 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 100V DC operation with a ±10% tolerance. This part is classified as obsolete, necessitating identification of active equivalent alternatives for continued circuit implementation. Equivalent parts maintain identical electrical and mechanical specifications while substitute parts provide functional alternatives with differing voltage ratings or physical dimensions within acceptable application parameters.

Engineering Selection Recommendations

Primary Recommendation: DMT1S15K-F

The DMT1S15K-F is the direct equivalent for the obsolete DMT1S15K. This part maintains identical electrical and mechanical specifications while advancing to active product status. The transition from RoHS Non-Compliant to RoHS3 Compliant status addresses regulatory requirements for new designs and procurement cycles. Lead spacing and footprint compatibility are preserved, enabling direct substitution without PCB redesign.

Secondary Recommendation: DME6S15K-F

The DME6S15K-F provides functional substitution with enhanced voltage handling capability (630V DC vs. 100V DC). This part is appropriate for applications where elevated voltage margins are beneficial. Physical dimensions are reduced (0.335" seated height vs. 0.464"), resulting in a more compact package suitable for space-constrained layouts. RoHS3 Compliance and Active product status provide long-term supply assurance. Lead spacing remains at 0.394" (10.00mm), maintaining footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can DMT1S15K-F directly replace DMT1S15K without PCB modification?

A: Yes. The DMT1S15K-F maintains identical lead spacing (0.394" / 10.00mm), size dimensions (0.512" L x 0.220" W), and maximum seated height (0.464"). Through-hole radial mounting and PC pin termination are identical. Direct PCB substitution is possible without layout changes.

Q: What is the primary advantage of DMT1S15K-F over the original DMT1S15K?

A: The DMT1S15K-F is an active product with RoHS3 compliance, addressing supply continuity and regulatory requirements. Electrical specifications (0.015 µF, ±10%, 100V DC) and operating temperature range (-55°C to 125°C) remain unchanged.

Q: When should DME6S15K-F be selected instead of DMT1S15K-F?

A: DME6S15K-F is selected for applications requiring elevated voltage ratings. The 630V DC rating provides six times the voltage margin of the 100V-rated alternatives. The more compact package (0.335" seated height) offers space advantages. Circuit voltage requirements and PCB layout constraints determine the appropriate selection.

Q: Are there physical dimension differences between the substitute parts?

A: DMT1S15K and DMT1S15K-F are physically identical (13.00mm x 5.60mm, 11.78mm seated height). DME6S15K-F is slightly smaller (12.50mm x 5.50mm, 8.50mm seated height). Lead spacing remains constant at 10.00mm for all three parts, preserving footprint compatibility.

Q: Do all substitute parts share the same operating temperature range?

A: Yes. DMT1S15K, DMT1S15K-F, and DME6S15K-F all operate across -55°C to 125°C, maintaining thermal specification compatibility across the product family.

Q: What is the impact of RoHS3 Compliance status?

A: RoHS3 compliance (DMT1S15K-F and DME6S15K-F) indicates conformance with European Union restriction of hazardous substances regulations. The obsolete DMT1S15K carries RoHS Non-Compliant status. For new production and long-term supply assurance, RoHS3-compliant alternatives are preferred.
