GP447 Ceramic Capacitor 47pF 1kV Equivalent & Substitute Parts

Part Overview

The GP447 is a 47 pF ceramic capacitor rated at 1000V (1kV) manufactured by Cornell Dubilier Electronics (CDE) with SL temperature coefficient and radial disc package configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates across a temperature range of -30°C to 85°C and is suitable for general-purpose applications requiring high-voltage ceramic capacitance in through-hole mounting configurations.

Voltage rating: 1000V minimum (equal or higher acceptable)
Mounting type: Through Hole (radial configuration)
Package type: Radial, Disc
Lead spacing: 0.252" (6.40mm) preferred for direct PCB compatibility

Secondary Compatibility Factors:

Temperature coefficient: SL preferred for thermal stability equivalence
Tolerance: ±10% acceptable (±5% represents improved tolerance)
Operating temperature range: Extended ranges (-55°C to 125°C) provide broader operational envelope
RoHS3 compliance: Required for regulatory alignment

Substitutes are grouped into two categories:

Category A - Direct Electrical & Mechanical Equivalents (SL Temperature Coefficient): Parts S470K25SL0N63J5R, S470K25SL0N63K5R, and S470K25SL0N6TJ6R maintain identical electrical specifications (47 pF, ±10%, 1kV, SL) with extended operating temperature ranges and active product status.

Category B - Enhanced Specifications (Alternative Temperature Coefficients): Parts 561R10TCCQ47 and 561R1DF0Q47 provide improved tolerance (±5%) and extended temperature ranges but employ different temperature coefficients (C0G/NP0 and N1500 respectively), suitable for applications requiring superior temperature stability.

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select S470K25SL0N6TJ6R when PCB layout accommodates the 0.197" (5.00mm) lead spacing. This part maintains identical electrical specifications (47 pF, ±10%, 1kV, SL) with extended operating temperature range (-55°C to 125°C) and active product status. Tape & Reel packaging provides high-volume procurement efficiency with 8200 pieces in stock. RoHS3 compliance ensures regulatory alignment.

For Lead Spacing Compatibility: If PCB design requires 0.252" (6.40mm) lead spacing matching the original GP447, select either S470K25SL0N63J5R or S470K25SL0N63K5R. Both maintain SL temperature coefficient and ±10% tolerance with active product status and extended temperature ranges. Lead spacing compatibility eliminates PCB redesign requirements.

For Enhanced Temperature Stability: Select 561R10TCCQ47 (Vishay Cera-Mite 561R series) when applications require superior temperature coefficient performance. This part provides C0G/NP0 temperature coefficient with ±5% tolerance and -55°C to 105°C operating range. Lead spacing remains at 0.252" (6.40mm) for direct PCB compatibility. Low dissipation factor specification supports high-frequency applications.

For Compact Form Factor: Select 561R1DF0Q47 when space constraints require minimum physical dimensions. This part features 0.252" (6.40mm) diameter with N1500 temperature coefficient and ±5% tolerance. Operating temperature range extends to -55°C to 105°C. Note: REACH status is affected for this part number.

Compliance Verification: All substitute parts maintain ROHS3 compliance and EAR99 ECCN classification. Moisture sensitivity level is not applicable for all listed parts. HTSUS codes align with ceramic capacitor classification (8532.23.0060 or 8532.24.0060).

Frequently Asked Questions (FAQ)

Q: Can S470K25SL0N6TJ6R replace GP447 directly on existing PCBs?

A: Direct replacement requires PCB lead hole spacing verification. S470K25SL0N6TJ6R features 0.197" (5.00mm) lead spacing versus GP447's 0.252" (6.40mm). If PCB holes are spaced at 0.252", use S470K25SL0N63J5R or S470K25SL0N63K5R instead. If PCB holes are spaced at 0.197", S470K25SL0N6TJ6R provides direct compatibility.

Q: What is the difference between SL and C0G/NP0 temperature coefficients?

A: SL temperature coefficient (GP447, S470K25SL0N63J5R, S470K25SL0N63K5R, S470K25SL0N6TJ6R) provides standard temperature stability suitable for general-purpose applications. C0G/NP0 temperature coefficient (561R10TCCQ47) provides superior temperature stability with negligible capacitance change across temperature extremes, required for precision circuits. N1500 temperature coefficient (561R1DF0Q47) offers intermediate temperature stability characteristics.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant. However, 561R1DF0Q47 has REACH status listed as affected, requiring verification against specific REACH substance restrictions for your application jurisdiction.

Q: Which substitute offers the highest inventory availability?

A: S470K25SL0N6TJ6R provides the highest inventory with 8200 pieces in stock (Tape & Reel packaging). This part maintains identical electrical specifications to GP447 with extended operating temperature range and active product status.

Q: Can I use ±5% tolerance parts as substitutes for ±10% tolerance applications?

A: Yes, ±5% tolerance parts (561R10TCCQ47 and 561R1DF0Q47) are acceptable substitutes for ±10% tolerance requirements. Tighter tolerance provides improved capacitance accuracy and is backward-compatible with ±10% specifications.

Q: What is the impact of extended operating temperature ranges?

A: Substitute parts with -55°C to 125°C operating ranges (S470K25SL0N63J5R, S470K25SL0N63K5R, S470K25SL0N6TJ6R) provide broader environmental performance compared to GP447's -30°C to 85°C range. Extended ranges support applications in extreme temperature environments without performance degradation.

Q: Does packaging format (Bulk vs. Tape & Reel) affect electrical performance?

A: No, packaging format does not affect electrical performance. Bulk packaging suits low-volume or prototype applications. Tape & Reel packaging (S470K25SL0N6TJ6R) optimizes high-volume automated assembly processes and provides superior inventory availability.

Q: Are there physical dimension constraints I should consider?

A: Yes, physical dimensions vary among substitutes. GP447 features 0.236" diameter with 0.394" seated height. 561R10TCCQ47 is larger at 0.441" diameter with 0.566" seated height. S470K25SL0N63J5R, S470K25SL0N63K5R, and S470K25SL0N6TJ6R feature 0.256" diameter with 0.413" seated height. Verify PCB layout clearances before selection.
