Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6LS681KCECC are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Capacitance: 680 pF (exact match)
• Tolerance: ±10% (exact match)
• Voltage Rating: 2000V (2kV) minimum (exact match)
• Temperature Coefficient: Y5P (B) (exact match)
• Package Type: Radial, Disc (exact match)
• Mounting Type: Through Hole (exact match)

Mechanical Considerations:

• Lead configuration and spacing may vary within the radial disc package category
• Physical dimensions (diameter, height, lead spacing) are secondary to electrical parameters but must accommodate board layout constraints

The identified substitutes from Vishay Beyschlag/Draloric/BC Components maintain all critical electrical parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both Vishay substitute parts (S681K29Y5PP63K5R and S681K29Y5PP6BK7R) provide active product status with ROHS3 compliance, addressing the obsolescence of the original 6LS681KCECC component. All three parts maintain identical electrical specifications: 680 pF capacitance, ±10% tolerance, 2000V rating, and Y5P temperature coefficient.

The primary differentiation between substitute options is lead spacing: S681K29Y5PP63K5R features 5.00mm spacing, while S681K29Y5PP6BK7R features 7.50mm spacing. Selection between these options depends on existing board layout and hole pattern compatibility. Both substitutes employ formed, kinked leads rather than straight leads, which may require board layout verification for proper component seating and solder joint formation.

The operating temperature range of the Vishay substitutes (-30°C ~ 125°C) is narrower than the original part (-40°C ~ 125°C) at the lower temperature extreme. Applications requiring operation below -30°C must evaluate this specification change against system requirements.

Frequently Asked Questions (FAQ)

Q: Can S681K29Y5PP63K5R and S681K29Y5PP6BK7R be used interchangeably with 6LS681KCECC?

A: Both Vishay parts are electrically equivalent to the 6LS681KCECC, matching all critical electrical parameters. However, they differ in lead spacing (5.00mm and 7.50mm respectively versus the original 10.00mm) and employ formed leads instead of straight leads. Board layout compatibility must be verified before substitution.

Q: What is the difference between S681K29Y5PP63K5R and S681K29Y5PP6BK7R?

A: Both parts are identical in electrical specifications and physical diameter. The primary difference is lead spacing: S681K29Y5PP63K5R has 5.00mm spacing, while S681K29Y5PP6BK7R has 7.50mm spacing. Selection depends on the hole pattern of the target PCB.

Q: Does the change in operating temperature range affect compatibility?

A: The Vishay substitutes operate from -30°C to 125°C, compared to the original -40°C to 125°C. If the application requires operation below -30°C, the substitute parts may not be suitable. Verify system temperature requirements before selection.

Q: Are the substitute parts RoHS compliant?

A: Yes, both Vishay substitute parts (S681K29Y5PP63K5R and S681K29Y5PP6BK7R) are ROHS3 compliant. The original 6LS681KCECC RoHS status was not specified.

Q: What is the significance of formed leads versus straight leads?

A: The original 6LS681KCECC features straight leads, while the Vishay substitutes feature formed, kinked leads. This affects component insertion and seating on the PCB. Formed leads may require different insertion techniques and tooling compared to straight leads.
