6LT151KODCM Equivalent & Substitute Parts

Part Overview

The 6LT151KODCM is a 150 pF ceramic capacitor rated for 3000V (3kV) with Y5P temperature coefficient, manufactured by KYOCERA AVX. This radial, disc-type capacitor is designed for general purpose applications requiring high voltage performance. The part is currently obsolete, making equivalent substitute parts necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitute parts for the 6LT151KODCM are qualified based on matching the following critical electrical and mechanical parameters:

Capacitance: 150 pF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 3000V (3kV) (exact match required)
Temperature Coefficient: Y5P (B) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Disc (exact match required)
Lead Style: Formed Leads - Kinked (exact match required)

All three substitute parts from Vishay Beyschlag/Draloric/BC Components meet these core electrical specifications. Variations exist in physical dimensions (body diameter, height, and lead spacing) and packaging format (Bulk or Tape & Reel), which determine suitability based on PCB layout constraints and procurement requirements.

Engineering Selection Recommendations

All three Vishay substitute parts are active products with ROHS3 compliance and REACH unaffected status, providing regulatory continuity for new designs and production support.

S151K33Y5PR6TK5R is the closest dimensional match to the original 6LT151KODCM, sharing the identical 0.197" (5.00mm) lead spacing. This part is supplied in Tape & Reel format, suitable for automated assembly processes. Select this part when PCB layout constraints require the original lead spacing and high-volume production is planned.

S151K33Y5PR63L6R offers an intermediate lead spacing of 0.252" (6.40mm) in Bulk packaging. This part accommodates moderate PCB layout flexibility while maintaining manual or semi-automated assembly compatibility.

S151K33Y5PR63K7R features the widest lead spacing at 0.295" (7.50mm) in Bulk packaging. This configuration provides maximum PCB layout flexibility for designs with relaxed spacing requirements.

All substitutes operate across -30°C to 125°C, which covers the upper temperature range of the original part. Designs requiring the full -40°C lower temperature limit of the original 6LT151KODCM must account for this specification difference.

Frequently Asked Questions (FAQ)

Q: Can S151K33Y5PR6TK5R be used as a direct replacement for 6LT151KODCM?

A: Yes, electrically and mechanically. The S151K33Y5PR6TK5R matches all critical parameters: 150 pF capacitance, ±10% tolerance, 3000V rating, Y5P temperature coefficient, and identical 0.197" (5.00mm) lead spacing. The primary difference is the increased body size (0.335" diameter vs. 0.276" diameter) and height (0.492" vs. 0.157"), which may require PCB layout verification. Operating temperature range differs: -30°C to 125°C versus -40°C to 125°C.

Q: What is the difference between the three substitute parts?

A: All three parts are electrically identical. Differences are physical dimensions and packaging:

S151K33Y5PR6TK5R: 5.00mm lead spacing, Tape & Reel packaging
S151K33Y5PR63L6R: 6.40mm lead spacing, Bulk packaging
S151K33Y5PR63K7R: 7.50mm lead spacing, Bulk packaging

Q: Which substitute should I select for a new PCB design?

A: Selection depends on PCB layout constraints and assembly method. If the original 5.00mm lead spacing is required, use S151K33Y5PR6TK5R. For designs with flexible spacing, S151K33Y5PR63L6R or S151K33Y5PR63K7R provide additional layout options. Tape & Reel packaging (S151K33Y5PR6TK5R) is preferred for automated assembly; Bulk packaging suits manual or semi-automated processes.

Q: Are all substitutes RoHS compliant?

A: Yes. All three Vishay substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the operating temperature difference between the original and substitutes?

A: The original 6LT151KODCM operates from -40°C to 125°C. All three Vishay substitutes operate from -30°C to 125°C. Designs requiring operation below -30°C must use the original KYOCERA AVX part or identify alternative solutions.
