DLR1S15K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DLR1S15K-F is a 0.015 µF polyester film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 100V DC operation with ±10% tolerance. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and maintenance applications. The radial through-hole configuration and general-purpose design make this capacitor suitable for legacy circuit boards requiring direct replacement or functional equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLR1S15K-F is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.015 µF (exact match required)
• Tolerance: ±10% (matching tolerance band)
• Voltage rating: Minimum 100V DC (equal or higher acceptable)
• Dielectric material: Polyester (functional equivalence)

Mechanical Equivalence Criteria:

• Mounting type: Through hole radial configuration
• Termination style: PC pins for PCB insertion
• Physical form factor: Radial lead spacing compatible with 0.177" (4.50mm) or 0.200" (5.08mm) hole patterns

Compliance Criteria:

• RoHS3 compliance required for modern production environments
• REACH unaffected status for unrestricted use

The substitute part BFC237021153 meets all electrical and mechanical equivalence requirements while offering active product status and extended operating temperature range.

Engineering Selection Recommendations

Primary Substitute: BFC237021153

The BFC237021153 from Vishay Beyschlag/Draloric/BC Components provides full electrical equivalence to the DLR1S15K-F across all critical parameters: capacitance, tolerance, voltage rating, and dielectric material. The substitute maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with modern manufacturing and supply chain requirements.

The extended operating temperature range (-55°C to +105°C) of the BFC237021153 exceeds the original specification (-40°C to +85°C), providing enhanced thermal performance for applications subject to wider environmental conditions.

Lead Spacing Consideration:

The lead spacing differs between the main part (0.177" / 4.50mm) and substitute (0.200" / 5.08mm). PCB hole pattern compatibility must be verified before implementation. If the original PCB layout cannot accommodate the 0.200" spacing, mechanical adaptation or PCB rework may be required.

Product Status:

The DLR1S15K-F is obsolete with limited inventory (706 pcs). The BFC237021153 maintains active product status with significantly higher availability (2131 pcs), supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the BFC237021153 be used as a direct drop-in replacement for the DLR1S15K-F?

A: Electrical substitution is valid. Mechanical compatibility depends on PCB hole spacing. The original design uses 0.177" (4.50mm) lead spacing, while the substitute uses 0.200" (5.08mm). Verify PCB layout before installation.

Q: What is the difference between polyester and metallized polyester dielectric materials?

A: Both are polyester-based dielectrics. Metallized polyester incorporates a thin metal layer, which is the case for the BFC237021153. This does not affect functional equivalence for the specified electrical parameters.

Q: Does the extended temperature range of the BFC237021153 affect circuit performance?

A: The substitute's operating range (-55°C to +105°C) encompasses the original specification (-40°C to +85°C). Extended range capability does not degrade performance within the original operating window.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the DLR1S15K-F and BFC237021153 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the lead spacing tolerance for radial film capacitors?

A: Lead spacing is a fixed mechanical dimension. The DLR1S15K-F specifies 0.177" (4.50mm), while the BFC237021153 specifies 0.200" (5.08mm). These are not interchangeable without PCB modification.

Q: Can the BFC237021153 be used in automotive applications?

A: Yes. The BFC237021153 carries AEC-Q200 automotive qualification and is rated for automotive applications, providing enhanced reliability for automotive circuit designs.
