Key Parameters

Substitute Part Grouping Explanation

Substitution of the 105MABA01KIS is determined by the following critical parameters:

Electrical Parameters:

• Capacitance value must equal 1 µF
• Tolerance must be ±10% or tighter
• Voltage rating (DC) must meet or exceed 800V
• Dielectric material must be polypropylene metallized film

Mechanical Parameters:

• Mounting type must be through-hole radial
• Termination must be PC pins
• Operating temperature range must encompass -40°C to 100°C

Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status required

The substitute part 105PHB850K2J meets all critical electrical and mechanical parameters. The higher DC voltage rating (850V) and AC voltage rating (450V) provide enhanced voltage margin. The radial through-hole configuration with PC pin termination ensures direct mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 105PHB850K2J is a direct electrical and mechanical substitute for the 105MABA01KIS. Both components are manufactured by the same supplier and share identical capacitance, tolerance, dielectric material, and operating temperature specifications. The substitute part maintains full RoHS3 compliance and REACH unaffected status.

The 105PHB850K2J carries active product status, ensuring continued availability and supply chain reliability compared to the obsolete 105MABA01KIS. The elevated voltage ratings (850V DC / 450V AC) provide additional safety margin in motor run applications without introducing incompatibility.

Physical dimensions differ slightly between the two parts. The 105PHB850K2J measures 1.673" L x 0.669" W with 1.102" seated height and 1.476" lead spacing, compared to the 105MABA01KIS dimensions of 1.555" L x 0.866" W with 1.024" seated height and 1.378" lead spacing. PCB layout verification is required to confirm mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can the 105PHB850K2J directly replace the 105MABA01KIS in motor run applications?

A: Yes. Both components share identical capacitance (1 µF), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C to 100°C), and mounting configuration (through-hole radial with PC pins). The substitute part's higher voltage ratings provide enhanced performance margin.

Q: What are the physical differences between these two parts?

A: The 105PHB850K2J is slightly larger in length (1.673" vs 1.555") and narrower in width (0.669" vs 0.866"). Lead spacing increases from 1.378" to 1.476". PCB layout must be verified to confirm the substitute fits within available space constraints.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 105MABA01KIS and 105PHB850K2J are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the 105PHB850K2J rated for higher voltage?

A: The 105PHB850K2J belongs to the PHB series, which features enhanced voltage ratings (850V DC / 450V AC) compared to the MAB series (800V DC / 400V AC). This higher rating does not affect compatibility and provides additional operational safety margin.

Q: What is the availability status of each part?

A: The 105MABA01KIS is classified as obsolete with 772 units in current inventory. The 105PHB850K2J is active product with 1047 units in stock, ensuring long-term supply chain continuity.
