DLR1P15K-F Equivalent & Substitute Parts

Part Overview

The DLR1P15K-F is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 100V DC voltage rating and ±10% tolerance. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing applications. The DLR series represents an earlier generation of radial film capacitors. Active equivalent models from CDE and other manufacturers provide improved performance characteristics, including extended operating temperature ranges and metallized dielectric construction, while maintaining electrical compatibility with the original specification.

Mounting Type: Through Hole
Package Type: Radial
Lead Spacing: 0.295" (7.50mm)
Dielectric Material: Polyester or polyester-based composition

Acceptable Variation Parameters:

Voltage Rating: Substitute must equal or exceed 100V DC and 63V AC
Tolerance: Substitute may be equal (±10%) or tighter (±5%)
Operating Temperature: Substitute must cover the -40°C ~ 85°C range; extended ranges are acceptable
Dielectric Construction: Metallized polyester construction is acceptable and represents an upgrade from standard polyester

Regulatory Compliance:

Engineering Selection Recommendations

Direct Replacement (100V DC Rating, Matching Tolerance):

For applications requiring exact tolerance matching with the original DLR1P15K-F (±10%), the CDE 167154K100B-F and 184154K100RBA-F / 184154K100RBB-F are direct electrical equivalents. These parts maintain the ±10% tolerance specification while providing metallized polyester construction and extended operating temperature range (-55°C ~ 125°C). The 167 series is available in bulk packaging, while the 184 series is supplied in tape & reel format. All three parts are active products with full RoHS3 compliance.

Upgraded Tolerance (100V DC Rating, Tighter Tolerance):

The CDE 167154J100B-F and 184154J100RBA-F / 184154J100RBB-F offer ±5% tolerance, representing an improvement over the original ±10% specification. These parts are electrically and mechanically compatible with the DLR1P15K-F while providing superior capacitance accuracy. Both bulk and tape & reel packaging options are available.

Higher Voltage Rating (250V DC):

The CDE DME2P15K-F and EPCOS B32520C3154J000 provide 250V DC rating with the same 0.15 µF capacitance. These parts are suitable for applications where higher voltage margin is required. The DME2P15K-F is a CDE product maintaining manufacturer consistency, while the B32520C3154J000 represents a cross-manufacturer equivalent from EPCOS with AEC-Q200 automotive rating.

Cross-Manufacturer Equivalent (100V DC):

The EPCOS B32520C1154J000 provides 100V DC rating with ±5% tolerance and metallized polyester-stacked construction. This part carries AEC-Q200 automotive qualification and is available in bulk packaging with extended inventory (16,865 units). The Vishay BFC237121154 (MKT371 series) offers ±10% tolerance matching the original specification with -55°C ~ 105°C operating range. Lead spacing is 0.300" (7.62mm), which differs slightly from the 0.295" (7.50mm) standard but remains within typical PCB tolerance for radial component placement.

Product Status Consideration:

All substitute parts listed are active products with current manufacturing status, ensuring long-term availability and supply chain stability. The original DLR1P15K-F obsolete status necessitates transition to one of these active alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original DLR1P15K-F?

A: Yes. The DLR1P15K-F is rated for 100V DC. Substitute parts with 250V DC rating (DME2P15K-F, B32520C3154J000) are electrically compatible and provide additional voltage margin. Higher voltage rating does not negatively affect circuit performance in applications designed for 100V operation.

Q: What is the difference between the CDE 167 and 184 series substitutes?

A: Both series provide identical electrical specifications (0.15 µF, 100V DC, polyester metallized construction, -55°C ~ 125°C operating range). The primary difference is packaging: the 167 series is supplied in bulk format, while the 184 series is supplied in tape & reel format. Selection depends on assembly process requirements.

Q: Are the CDE 167154J100B-F and 167154K100B-F interchangeable?

A: These parts are mechanically and electrically compatible with identical voltage ratings and operating temperature ranges. The difference is tolerance: 167154J100B-F has ±5% tolerance while 167154K100B-F has ±10% tolerance. Either part can replace the DLR1P15K-F; the ±5% version provides superior capacitance accuracy.

Q: Why do some substitutes have metallized polyester construction while the original has standard polyester?

A: Metallized polyester construction is an industry upgrade that provides improved performance characteristics including self-healing properties and reduced ESR. This construction is fully compatible with applications designed for standard polyester film capacitors and represents an enhancement rather than a deviation from the original specification.

Q: Can I use the EPCOS B32520C3154J000 (250V) in place of the DLR1P15K-F (100V)?

A: Yes. The B32520C3154J000 maintains the same 0.15 µF capacitance and lead spacing while providing 250V DC rating. This part is suitable for any application originally designed for the 100V DLR1P15K-F. The higher voltage rating provides additional safety margin without affecting circuit operation.

Q: What is the significance of the lead spacing difference in the Vishay BFC237121154?

A: The BFC237121154 has 0.300" (7.62mm) lead spacing compared to the standard 0.295" (7.50mm) of the DLR1P15K-F. This 0.005" difference falls within typical PCB manufacturing tolerances for radial component hole patterns. Mechanical fit compatibility should be verified for the specific PCB design before implementation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference are RoHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Which substitute offers the best long-term availability?

A: The EPCOS B32520C1154J000 has the highest current inventory (16,865 units) and is an active product from a major manufacturer. The CDE 167 and 184 series are also active products with substantial inventory levels (1,094 to 1,148 units). All listed substitutes are active products with ongoing manufacturing support.

Q: Can I mix different substitute parts in the same circuit board assembly?

A: Yes. All substitute parts meet the same electrical specifications for the DLR1P15K-F application. Mixing different manufacturers or series is acceptable from an electrical standpoint. However, assembly process considerations (bulk vs. tape & reel packaging) may influence production efficiency.
