GM103K Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The GM103K is a 10000 pF ceramic capacitor rated for 500V operation with Y5P temperature coefficient, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing procurement and design requirements. The radial, disc-style through-hole package serves general-purpose applications requiring stable capacitance across the specified temperature range of -30°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GM103K is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 10000 pF
• Tolerance: ±10%
• Voltage rating: 500V minimum
• Temperature coefficient: Y5P (B)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole
• Package configuration: Radial, Disc
• Lead style: Compatible with PCB hole spacing and assembly processes

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status
• ECCN and HTSUS classifications maintained

The substitute part D103K69Y5PL63J7R meets all electrical equivalence criteria and maintains mechanical compatibility through radial disc configuration with through-hole mounting. Physical dimensions and lead spacing differ within acceptable tolerances for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The D103K69Y5PL63J7R from Vishay Beyschlag/Draloric/BC Components is a direct electrical equivalent to the obsolete GM103K. Both components maintain identical capacitance, tolerance, voltage rating, and temperature coefficient specifications required for general-purpose applications.

Compliance Status: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Product Availability: The substitute part maintains active manufacturing status with 817 units in current inventory, ensuring long-term procurement viability compared to the obsolete GM103K.

Physical Considerations: The substitute exhibits dimensional and lead configuration differences that require PCB-level verification. The kinked lead style and modified lead spacing (7.50mm versus 9.50mm) necessitate confirmation of compatibility with existing PCB hole patterns and assembly tooling. The increased body diameter (17.50mm versus 16.30mm) requires clearance verification in confined mounting areas.

Frequently Asked Questions (FAQ)

Q: Can the D103K69Y5PL63J7R directly replace the GM103K without PCB modification?

A: Electrical substitution is direct. However, physical lead spacing differs (7.50mm versus 9.50mm), and lead style differs (kinked versus straight). PCB hole pattern compatibility must be verified before implementation.

Q: What is the significance of the Y5P temperature coefficient designation?

A: Y5P (B) indicates a ceramic capacitor with ±10% capacitance change across the -30°C to 85°C operating range. Both the main part and substitute maintain this specification, ensuring equivalent performance in temperature-variable environments.

Q: Does the substitute's extended operating temperature range (-30°C to 125°C) affect compatibility?

A: The extended range represents enhanced capability beyond the original specification. For applications limited to -30°C to 85°C operation, both parts perform identically within the required envelope.

Q: Are there lead-forming considerations for the substitute part?

A: The D103K69Y5PL63J7R features kinked formed leads, differing from the straight leads of the GM103K. Lead-forming compatibility depends on PCB hole spacing and assembly equipment specifications.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component use in regulated markets.

Q: How do dimensional differences affect PCB layout?

A: The substitute exhibits a 0.689" diameter (versus 0.642") and modified lead spacing. PCB designs must accommodate the larger body envelope and verify hole pattern alignment with the 7.50mm lead spacing.
