Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECK-AHD681KB is determined by strict equivalence across the following critical parameters:

• Capacitance value: 680 pF
• Tolerance: ±10%
• Voltage rating: 2000V (2kV) minimum
• Temperature coefficient: Y5P (B)
• Mounting configuration: Through-hole radial, disc package
• Lead configuration: Formed leads (kinked leads acceptable for mechanical compatibility)

Both substitute parts meet these core electrical and mechanical requirements. Physical dimensions may vary within acceptable assembly tolerances for through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both Vishay substitute parts (S681K29Y5PP63K5R and S681K29Y5PP6BK7R) provide direct electrical equivalence to the obsolete ECK-AHD681KB. The Vishay components carry active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

The primary distinction between the two Vishay substitutes is lead spacing: S681K29Y5PP63K5R features 5.00mm lead spacing, while S681K29Y5PP6BK7R maintains 7.50mm lead spacing matching the original Panasonic part. Selection should be based on PCB layout requirements and existing hole patterns.

Both substitutes operate across an extended low-temperature range (-30°C versus -25°C), providing improved performance margin in cold environments.

Frequently Asked Questions (FAQ)

Q: Can S681K29Y5PP63K5R and S681K29Y5PP6BK7R be used interchangeably with ECK-AHD681KB?

A: Both parts are electrically equivalent. Physical interchangeability depends on PCB hole spacing. S681K29Y5PP6BK7R matches the original 7.50mm lead spacing; S681K29Y5PP63K5R requires 5.00mm spacing.

Q: What is the difference between the two Vishay substitutes?

A: The primary difference is lead spacing. S681K29Y5PP63K5R has 5.00mm spacing and smaller body diameter (7.50mm). S681K29Y5PP6BK7R has 7.50mm spacing and matching body diameter to the original part.

Q: Are the substitute parts RoHS compliant?

A: Yes, both Vishay substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements.

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

A: The substitutes maintain identical Y5P temperature coefficient characteristics. The extended low-temperature range (-30°C) provides additional operational margin without affecting nominal performance.

Q: Can these parts be used in new designs?

A: Yes. Both substitute parts carry active product status with established supply chains, making them suitable for new designs requiring 680 pF, 2kV, Y5P ceramic capacitors in radial through-hole configuration.
