K680J10C0GF53L2 Equivalent & Substitute Parts

Part Overview

The K680J10C0GF53L2 is a 68 pF ±5% 50V ceramic capacitor with C0G/NP0 temperature coefficient manufactured by Vishay Beyschlag/Draloric/BC Components in the Mono-Kap™ K series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently active in production. Equivalent and substitute parts are identified based on matching electrical specifications and compatible mechanical parameters for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the K680J10C0GF53L2 is determined by the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 68 pF
• Tolerance: ±5%
• Voltage Rating: 50V
• Temperature Coefficient: C0G/NP0
• Operating Temperature Range: -55°C ~ 125°C

Mechanical Parameters (Must Be Compatible):

• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.098" (2.50mm) or 0.197" (5.00mm) acceptable for board layout flexibility
• Lead Style: Straight or Formed Leads - Kinked acceptable

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected

Substitute parts are grouped by manufacturer and lead spacing configuration. All identified substitutes maintain identical electrical performance while offering variations in physical dimensions and lead geometry suitable for different PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): K680J15C0GF53L2 from Vishay Beyschlag/Draloric/BC Components is the primary substitute. It maintains identical electrical specifications and lead spacing as the original part while offering higher inventory availability (17123 units). Both parts are Active status products with ROHS3 compliance.

For Alternative Sourcing: RDE5C1H680J0P1H03B from Murata Electronics provides an active-status alternative with matching lead spacing (0.098" / 2.50mm) and identical electrical parameters. This part is suitable for applications where Murata components are preferred or required.

RDE5C1H680J0K1H03B from Murata Electronics offers the same electrical specifications with 0.197" (5.00mm) lead spacing, accommodating PCB layouts with wider pad spacing.

For Legacy System Maintenance: FK18C0G1H680JN020 and FK28C0G1H680JN000 from TDK Corporation are classified as "Not For New Designs" but remain available for maintenance and repair of existing systems. These parts maintain full electrical compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can K680J15C0GF53L2 be used as a direct replacement for K680J10C0GF53L2? A: Yes. Both parts share identical electrical specifications (68 pF, ±5%, 50V, C0G/NP0) and lead spacing (0.098" / 2.50mm). The difference in part number reflects a variation in physical dimensions. Verify PCB layout clearance for the slightly larger body size (0.157" L x 0.102" W versus 0.142" L x 0.091" W).

Q: What is the difference between 0.098" and 0.197" lead spacing? A: Lead spacing refers to the distance between the two radial leads. The 0.098" (2.50mm) spacing is standard for compact layouts, while 0.197" (5.00mm) spacing accommodates PCB designs with wider pad separation. Selection depends on your circuit board hole pattern.

Q: Are TDK FK series parts suitable for new designs? A: FK18C0G1H680JN020 and FK28C0G1H680JN000 are marked "Not For New Designs." These parts are available for existing system support and repair but should not be specified for new product development. Use active-status alternatives such as Vishay K680J15C0GF53L2 or Murata RDE5C1H series for new designs.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original K680J10C0GF53L2 compliance profile.

Q: What is the significance of C0G versus NP0 temperature coefficient designation? A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic. Both terms describe capacitors with minimal capacitance change across the -55°C to 125°C operating range. All substitute parts listed use this same temperature coefficient.

Q: Can I use parts with different lead styles (Straight versus Formed Leads - Kinked)? A: Lead style differences affect insertion and soldering characteristics but do not impact electrical performance. Straight leads (K680J10C0GF53L2, K680J15C0GF53L2, RDE5C1H680J0P1H03B) are standard for automated insertion. Formed leads (FK18C0G1H680JN020, FK28C0G1H680JN000, RDE5C1H680J0K1H03B) are pre-bent for manual insertion. Selection depends on your assembly process.
