• Voltage Rating (AC): 305V
• Voltage Rating (DC): 630V
• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Type: Through Hole (Radial)
• Operating Temperature Range: -40°C ~ 110°C
• Termination: PC Pins
• Package / Case: Radial
• Lead Spacing: 0.886" (22.50mm)
• Physical Dimensions: 1.024" L x 0.394" W (26.00mm x 10.00mm)
• Height - Seated (Max): 0.768" (19.50mm)

Identified Substitutes:

• MXH105K305G20 (Cornell Dubilier Electronics - CDE)
• MXT105K305G20 (Cornell Dubilier Electronics - CDE)

Both substitute parts meet the electrical and mechanical parameter requirements for direct substitution in safety/EMI suppression applications.

Frequently Asked Questions (FAQ)

Q: Can MXH105K305G20 and MXT105K305G20 be used interchangeably with R46KN4100JEN1K?

A: Both CDE parts meet the electrical and mechanical parameters specified for the R46KN4100JEN1K. They share identical capacitance (1 µF), tolerance (±10%), voltage ratings (305V AC / 630V DC), dielectric material (Polypropylene metallized), operating temperature range (-40°C ~ 110°C), mounting type (Through Hole Radial), physical dimensions, and termination specifications. Both are active products with REACH unaffected status and EAR99 export classification.

Q: What are the key differences between MXH105K305G20 and MXT105K305G20?

A: Both parts share identical electrical specifications and physical dimensions. The primary differences are: MXH105K305G20 is rated for automotive applications with AEC-Q200 compliance, while MXT105K305G20 carries an X2 safety rating. MXH105K305G20 has confirmed ROHS3 compliance in the provided data, while MXT105K305G20 does not specify this in the input parameters. MXT105K305G20 has higher inventory availability (4101 units vs. 2196 units).

Q: Are there any packaging differences between the main part and substitutes?

A: Yes. The R46KN4100JEN1K is supplied in Box packaging, while both MXH105K305G20 and MXT105K305G20 are supplied in Bulk packaging. The physical component dimensions and radial configuration remain identical across all three parts.

Q: Do all three parts comply with environmental regulations?

A: All three parts are REACH unaffected and carry EAR99 export classification. The R46KN4100JEN1K and MXH105K305G20 are confirmed ROHS3 compliant. MXT105K305G20 does not specify ROHS3 status in the provided input data.

Q: What is the lead spacing for these radial capacitors?

A: The lead spacing for both CDE substitute parts is 0.886" (22.50mm). This specification is not provided in the input data for the R46KN4100JEN1K, but the radial configuration and physical dimensions are consistent across all three parts.

Q: Which substitute part has the best inventory availability?

A: MXT105K305G20 has the highest inventory availability with 4101 units in stock, followed by MXH105K305G20 with 2196 units. The original R46KN4100JEN1K has 1156 units available.
