Equivalent & Substitute Parts for 155MABA01KHS

Part Overview

The 155MABA01KHS is a 1.5 µF film capacitor manufactured by Cornell Dubilier / Illinois Capacitor, rated for 800V DC with ±10% tolerance and polypropylene metallized dielectric construction. This radial through-hole component is designed for motor run applications with an operating temperature range of -40°C to 100°C.

The product status is listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements. Substitute parts must maintain electrical compatibility while accommodating mechanical and packaging variations.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the 155MABA01KHS:

Direct Parametric Equivalents: Parts that maintain identical or near-identical electrical specifications and physical dimensions. These parts share the same capacitance (1.5 µF), tolerance (±10%), voltage rating (800V DC), dielectric material (polypropylene metallized), and lead spacing (27.50mm). Parametric equivalents include MABA014150KHL and MABA014150KHS from Nichicon, both manufactured in the same MAB series with matching dimensional and thermal characteristics.

Functional Substitutes: Parts that satisfy the core electrical requirements (1.5 µF capacitance, 800V DC or higher voltage rating, polypropylene metallized dielectric) but may differ in tolerance, voltage rating, operating temperature range, or physical dimensions. These substitutes are selected based on the following allowed parameters:

Capacitance: 1.5 µF (exact match required)
Voltage Rating (DC): 800V minimum (higher ratings acceptable)
Dielectric: Polypropylene (PP), Metallized (required)
Mounting: Through Hole, Radial (required)
Termination: PC Pins (required)
RoHS Status: ROHS3 Compliant (required)

Functional substitutes in this list include parts from EPCOS/TDK, Vishay, WIMA, and KEMET. These parts accommodate variations in tolerance (±10% to ±20%), voltage rating (800V to 1000V DC), operating temperature (-40°C to 110°C), and lead spacing (27.50mm to 37.50mm).

Engineering Selection Recommendations

Direct Replacement (No Design Modification Required):

MABA014150KHL and MABA014150KHS from Nichicon are parametric equivalents with identical electrical and mechanical specifications to the 155MABA01KHS. Both parts are active products with ROHS3 compliance and sufficient inventory. These parts maintain the same capacitance, tolerance, voltage rating, operating temperature range, and lead spacing. Selection between these two Nichicon variants depends on specific packaging or termination requirements not differentiated in the provided specifications.

Functional Substitutes (Design Verification Recommended):

F340X151548MKP2T0 (Vishay) maintains the same lead spacing (27.50mm) and voltage rating (800V DC) as the original part but features ±20% tolerance and extended operating temperature to 105°C. This part is suitable for applications where tighter tolerance is not critical.

B32914A5155M000 (EPCOS/TDK) provides higher voltage rating (1000V DC) with ±20% tolerance and extended temperature range (-40°C to 110°C). The same lead spacing (27.50mm) ensures PCB compatibility. This part is appropriate for designs requiring voltage derating margin.

R474R41505001K (KEMET) offers ±10% tolerance matching the original specification, 1000V DC rating, and maintains the 27.50mm lead spacing. This part includes AEC-Q200 automotive qualification and X2 rating, suitable for automotive and EMI/RFI suppression applications.

MKP1O141507H00KSSD (WIMA) and PHE844RR7150MR30L2 (KEMET) feature increased lead spacing (37.50mm) and higher voltage ratings (1000V DC). These parts require PCB footprint modification and are suitable only when physical space permits the larger dimensions.

All substitute parts maintain ROHS3 compliance and polypropylene metallized dielectric construction. Product status is active for all substitutes, ensuring long-term availability.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 155MABA01KHS?

A: Yes. A higher voltage rating (such as 1000V DC) is electrically compatible and provides additional safety margin. The circuit will function correctly as the capacitor will operate below its rated voltage. However, physical dimensions may differ, requiring verification of PCB footprint compatibility.

Q: What is the difference between parametric equivalents and functional substitutes?

A: Parametric equivalents (MABA014150KHL and MABA014150KHS) match all electrical and mechanical specifications of the original part, including tolerance, voltage rating, operating temperature, and lead spacing. Functional substitutes satisfy core requirements (capacitance, voltage, dielectric material, mounting type) but may differ in tolerance, temperature range, or physical dimensions. Parametric equivalents require no design verification; functional substitutes may require circuit analysis depending on application sensitivity.

Q: Does tolerance affect my circuit design?

A: Tolerance affects capacitance accuracy. The original part specifies ±10%, meaning actual capacitance ranges from 1.35 µF to 1.65 µF. Substitutes with ±20% tolerance range from 1.2 µF to 1.8 µF. If your circuit requires precise capacitance (such as in timing or filtering applications), verify that the wider tolerance remains acceptable. For motor run applications, ±20% tolerance is typically acceptable.

Q: Can I use a part with different lead spacing?

A: Lead spacing determines PCB hole positioning. The original part uses 27.50mm spacing. Substitutes with 37.50mm spacing (WIMA MKP1O141507H00KSSD and KEMET PHE844RR7150MR30L2) require PCB modification or manual lead bending. If your PCB is already manufactured with 27.50mm hole spacing, use only substitutes with matching lead spacing.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: Which substitute offers the best availability?

A: B32914A5155M000 from EPCOS/TDK offers the highest inventory (10,487 pcs), followed by MKP1O141507H00KSSD from WIMA (4,124 pcs). Both are active products with strong supply chain presence.

Q: Can I substitute the original part in a motor run application?

A: Yes. All listed substitutes are suitable for motor run applications. The original part and parametric equivalents (Nichicon MABA series) are specifically rated for motor run use. Functional substitutes maintain the required polypropylene metallized dielectric and voltage ratings necessary for motor run capacitor performance.
