GE101K Equivalent & Substitute Parts Reference

Part Overview

The GE101K is a 100 pF ceramic capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 50V rated voltage and Y5P temperature coefficient. This radial, disc-style through-hole component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part operates across a temperature range of -30°C to 85°C and maintains ±10% capacitance tolerance. ROHS3 compliance and REACH unaffected status confirm environmental regulatory alignment.

Substitute Part Grouping Explanation

Substitution logic for the GE101K is based on strict electrical and mechanical parameter matching. All substitute parts must maintain the following criteria:

Electrical Requirements:

Capacitance value: 100 pF (exact match)
Voltage rating: minimum 50V (equal or higher acceptable)
Tolerance: ±10% or tighter (±5% or ±2% acceptable)
Temperature coefficient: Y5P (B) for direct equivalents; C0G/NP0 or SL for functional alternatives with different thermal characteristics
Operating temperature range: must encompass -30°C to 85°C minimum

Mechanical Requirements:

Mounting type: Through Hole only
Package style: Radial, Disc configuration
Lead spacing: 0.098" (2.50mm) standard; 0.197" (5.00mm) acceptable with circuit board redesign consideration
Lead style: Straight or formed leads acceptable

Regulatory Requirements:

RoHS3 compliance mandatory
REACH unaffected status required

Substitute parts are grouped into two categories: Direct Equivalents (matching temperature coefficient Y5P) and Functional Alternatives (different temperature coefficients with superior or equivalent performance characteristics).

Engineering Selection Recommendations

Direct Equivalents (Y5P Temperature Coefficient):

D101K20Y5PH63L2R and D101K20Y5PH65L2R are the primary substitutes for GE101K. Both parts maintain the Y5P (B) temperature coefficient, matching the thermal stability characteristics of the original component. These Vishay parts carry Active product status, ensuring long-term availability and supply chain reliability. The 100V voltage rating exceeds the 50V requirement, providing additional design margin. Lead spacing of 0.098" (2.50mm) matches the original PCB footprint exactly, requiring no layout modifications. Both parts are ROHS3 compliant and suitable for new designs.

D101K20Y5PF6TJ5R offers identical electrical specifications with Y5P (B) coefficient and 50V rating. However, the 0.197" (5.00mm) lead spacing differs from the original, requiring PCB redesign. This part is supplied in Tape & Reel packaging, suitable for high-volume automated assembly.

Functional Alternatives (Enhanced Temperature Stability):

K101J15C0GF5TL2 (Vishay Mono-Kap™ K series) and FK18C0G1H101JN020 (TDK) provide C0G/NP0 temperature coefficient with superior thermal stability across -55°C to 125°C. These parts feature ±5% tolerance, tighter than the original ±10%. Both maintain 50V voltage rating and 0.098" (2.50mm) lead spacing. K101J15C0GF5TL2 carries Active status; FK18C0G1H101JN020 is Not For New Designs. C0G/NP0 coefficient provides near-zero temperature drift, beneficial for precision applications where the original Y5P ±10% temperature variation is unacceptable.

D101J20SL0F63L2R (Vishay) offers SL temperature coefficient with ±5% tolerance and 50V rating. Operating temperature range extends to -55°C to 125°C. Lead spacing matches at 0.098" (2.50mm). Active product status confirms availability.

D101G29U2JH63L2R and D101G29U2JH65L2R (Vishay) provide U2J temperature coefficient with ±2% tolerance and 100V rating. These parts deliver the tightest tolerance available and highest voltage margin. Operating temperature range is -55°C to 125°C. Lead spacing matches at 0.098" (2.50mm). Both carry Active status. U2J coefficient provides stable performance across extended temperature ranges.

Selection Criteria:

For direct replacement without PCB modification: Select D101K20Y5PH63L2R or D101K20Y5PH65L2R.

For applications requiring enhanced temperature stability: Select K101J15C0GF5TL2 or D101J20SL0F63L2R.

For applications requiring maximum tolerance precision: Select D101G29U2JH63L2R or D101G29U2JH65L2R.

All recommended substitutes maintain ROHS3 compliance and through-hole radial disc package configuration.

Frequently Asked Questions (FAQ)

Q: Can D101K20Y5PH63L2R directly replace GE101K without PCB modification?

A: Yes. Both parts share identical lead spacing of 0.098" (2.50mm), matching radial disc package style, and through-hole mounting type. The 100V voltage rating of the substitute exceeds the 50V requirement. Y5P (B) temperature coefficient matches exactly. No PCB layout changes are required.

Q: What is the difference between Y5P and C0G temperature coefficients?

A: Y5P (B) exhibits ±10% capacitance change across the operating temperature range, typical for general-purpose applications. C0G/NP0 provides near-zero temperature coefficient, maintaining stable capacitance across temperature extremes. Selection depends on circuit sensitivity to capacitance variation.

Q: Why does D101K20Y5PF6TJ5R have different lead spacing?

A: D101K20Y5PF6TJ5R features 0.197" (5.00mm) lead spacing compared to the standard 0.098" (2.50mm). This wider spacing accommodates different PCB hole patterns. Use this part only if your circuit board layout supports 5.00mm spacing, or if PCB redesign is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original GE101K.

Q: What is the inventory status of substitute parts?

A: D101K20Y5PH63L2R: 979 Pcs. D101K20Y5PH65L2R: 679 Pcs. D101J20SL0F63L2R: 994 Pcs. D101G29U2JH63L2R: 1086 Pcs. D101G29U2JH65L2R: 853 Pcs. K101J15C0GF5TL2: 3780 Pcs. FK18C0G1H101JN020: 7702 Pcs. All parts are new original stock.

Q: Can I use a 100V rated capacitor in a 50V circuit?

A: Yes. Voltage rating indicates the maximum safe operating voltage. Using a capacitor with higher voltage rating than required is acceptable and provides design margin. No circuit modification is necessary.

Q: What does "Active" product status mean?

A: Active status indicates the manufacturer continues production and supports the part for new designs. Obsolete status (GE101K) indicates discontinued production. Active parts ensure long-term supply chain availability.

Q: Which substitute offers the tightest capacitance tolerance?

A: D101G29U2JH63L2R and D101G29U2JH65L2R offer ±2% tolerance, the tightest available. Original GE101K and most alternatives provide ±10% or ±5% tolerance. Tighter tolerance is beneficial for precision circuits but not required for general-purpose applications.

Q: Is packaging type (Bulk vs. Tape & Reel) important for substitution?

A: Packaging affects handling and assembly processes but does not impact electrical or mechanical compatibility. Bulk packaging suits manual assembly; Tape & Reel suits automated pick-and-place equipment. Select based on assembly method, not circuit performance.
