6LS681KCGCC Equivalent & Substitute Parts

Part Overview

The 6LS681KCGCC is a 680 pF ceramic capacitor rated for 2000V (2kV) with Y5P temperature coefficient, manufactured by KYOCERA AVX in a radial disc configuration. This component is classified as obsolete, necessitating identification of active substitute parts that maintain electrical and mechanical compatibility for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 6LS681KCGCC is based on the following critical parameters that must remain constant:

• Capacitance value: 680 pF
• Tolerance: ±10%
• Voltage rating: 2000V (2kV)
• Temperature coefficient: Y5P (B)
• Mounting type: Through Hole
• Package configuration: Radial, Disc

The identified substitute parts S681K29Y5PP63K5R and S681K29Y5PP6BK7R, both manufactured by Vishay Beyschlag/Draloric/BC Components, satisfy all critical electrical parameters. Both substitutes are active products with ROHS3 compliance and maintain the same capacitance, tolerance, voltage rating, and temperature coefficient as the original component. Mechanical variations in lead spacing and lead style (formed leads - kinked versus straight) represent acceptable design accommodations within the through-hole radial disc category.

Parameter Comparison

Engineering Selection Recommendations

Both S681K29Y5PP63K5R and S681K29Y5PP6BK7R are suitable substitutes for the obsolete 6LS681KCGCC based on electrical equivalence and active product status. The Vishay Beyschlag/Draloric/BC Components substitutes provide ROHS3 compliance, addressing modern regulatory requirements not specified for the original component.

Selection between the two Vishay substitutes depends on PCB layout constraints. S681K29Y5PP63K5R features 0.197" (5.00mm) lead spacing, while S681K29Y5PP6BK7R provides 0.295" (7.50mm) lead spacing. Both substitutes exhibit increased height (0.453" versus 0.197") and reduced diameter (0.295" versus 0.394") compared to the original, requiring PCB footprint verification prior to implementation.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts electrically equivalent to the 6LS681KCGCC?

A: Yes. Both S681K29Y5PP63K5R and S681K29Y5PP6BK7R maintain identical capacitance (680 pF), tolerance (±10%), voltage rating (2000V), and temperature coefficient (Y5P) specifications. The operating temperature range for substitutes (-30°C ~ 125°C) is narrower than the original (-40°C ~ 125°C) but covers the upper temperature specification completely.

Q: What are the mechanical differences between the original and substitute parts?

A: The primary mechanical differences are lead spacing and lead configuration. The original 6LS681KCGCC has straight leads with 0.394" spacing. S681K29Y5PP63K5R has kinked leads with 0.197" spacing, while S681K29Y5PP6BK7R has kinked leads with 0.295" spacing. Both substitutes are smaller in diameter (7.50mm versus 10.00mm) but taller (11.50mm versus 5.00mm). PCB footprint compatibility must be confirmed before substitution.

Q: Can I use either substitute interchangeably?

A: Electrical interchangeability is confirmed. Mechanical interchangeability depends on PCB hole spacing and available vertical clearance. Select the substitute based on your PCB layout requirements: S681K29Y5PP63K5R for 5.00mm hole spacing or S681K29Y5PP6BK7R for 7.50mm hole spacing.

Q: What compliance certifications do the substitutes provide?

A: Both S681K29Y5PP63K5R and S681K29Y5PP6BK7R are ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original 6LS681KCGCC RoHS status was not specified.

Q: Why is the original part obsolete?

A: The 6LS681KCGCC is classified as obsolete by KYOCERA AVX. The identified substitutes from Vishay Beyschlag/Draloric/BC Components are active products with current manufacturing support and improved regulatory compliance.
