GP310 Equivalent & Substitute Parts Reference

Part Overview

The GP310 is a 100 pF ceramic capacitor rated at 1000V (1kV) with Y5P temperature coefficient, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The GP310 features radial, disc-type construction with through-hole mounting, suitable for general-purpose applications requiring high-voltage ceramic capacitance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GP310 is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters:

• Capacitance value: 100 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 1000V (1kV) minimum (equal or higher acceptable)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package type: Radial, Disc (exact match required)
• Lead spacing: 0.252" (6.40mm) (exact match required)
• Lead style: Straight (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required for regulatory compatibility)

Temperature Coefficient Consideration: Temperature coefficient specifications differ among substitute parts (Y5P, N2000, X5F, S3N). Each coefficient defines the capacitance change over temperature. Substitution is valid when the substitute's operating temperature range meets or exceeds the application requirements, and the coefficient specification is documented for the target circuit design.

All four substitute parts meet the core electrical, mechanical, and compliance requirements for GP310 replacement.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compatibility):

All four substitute parts are classified as active products with ROHS3 compliance, making them suitable for GP310 replacement in new designs and legacy system support.

561R1DF0T10 (Vishay Cera-Mite 561R Series): This substitute features N2000 temperature coefficient with extended operating range (-55°C ~ 105°C) and documented low dissipation factor. Selection is appropriate for applications requiring the GP310's electrical specifications with enhanced temperature performance.

562R10TST10 and 562R10TST10BA (Vishay Cera-Mite 562R Series): Both parts are functionally identical, differing only in packaging designation (BA variant). X5F temperature coefficient with -55°C ~ 105°C operating range provides broader thermal coverage than the GP310. These parts offer the highest inventory availability (3607 and 2977 units respectively), supporting procurement continuity.

S101K29S3NN63L6R (Vishay Beyschlag/Draloric/BC Components S Series): This substitute provides the widest operating temperature range (-55°C ~ 125°C) with S3N temperature coefficient. Largest physical diameter (0.295" vs. 0.236" for GP310) requires PCB layout verification. Highest inventory level (26912 units) ensures long-term availability.

Selection Criteria:

• For direct form-factor replacement with minimal PCB modification: 561R1DF0T10, 562R10TST10, or 562R10TST10BA
• For maximum thermal operating range: S101K29S3NN63L6R (verify PCB space for 0.295" diameter)
• For highest inventory availability: S101K29S3NN63L6R

Frequently Asked Questions (FAQ)

Q: Can I substitute the GP310 with any of these parts without circuit redesign?

A: Yes, all four substitute parts maintain identical capacitance (100 pF), tolerance (±10%), voltage rating (1000V), lead spacing (0.252"), and mounting type (through-hole radial). Direct PCB footprint compatibility is confirmed for 561R1DF0T10, 562R10TST10, and 562R10TST10BA. The S101K29S3NN63L6R has a larger diameter (0.295" vs. 0.236") and requires verification of available PCB space.

Q: What is the difference between temperature coefficients Y5P, N2000, X5F, and S3N?

A: Temperature coefficient designations specify how capacitance changes across the operating temperature range. Each coefficient follows a defined standard for capacitance variation. The GP310 uses Y5P (B), while substitutes use N2000, X5F, or S3N. All substitutes operate across wider temperature ranges (-55°C ~ 105°C or -55°C ~ 125°C) compared to the GP310 (-30°C ~ 85°C). Selection should confirm the substitute's temperature coefficient meets circuit performance requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all four substitute parts are ROHS3 compliant, matching the GP310's regulatory status. This ensures compatibility with modern manufacturing and environmental standards.

Q: Which substitute has the best availability?

A: The S101K29S3NN63L6R offers the highest inventory level at 26912 units in stock, followed by 562R10TST10 (3607 units) and 562R10TST10BA (2977 units). The 561R1DF0T10 has 660 units available.

Q: Can I use these substitutes interchangeably in the same design?

A: All four parts are electrically equivalent for the core specifications (100 pF, ±10%, 1000V, through-hole radial). However, physical dimensions vary slightly. The 561R1DF0T10, 562R10TST10, and 562R10TST10BA share identical 0.252" diameter and 0.252" lead spacing. The S101K29S3NN63L6R has a 0.295" diameter, requiring PCB layout verification before substitution.

Q: What REACH and ECCN classifications apply to these parts?

A: The GP310 and S101K29S3NN63L6R are REACH Unaffected. The 561R1DF0T10 is REACH Affected. All parts are classified as EAR99 for export control purposes. Verify REACH status compliance with your supply chain requirements.
