Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 684MABA01KHS are identified based on the following critical parameters that determine functional equivalence:

Primary Equivalence Criteria:

• Capacitance value: 0.68 µF (exact match required)
• Tolerance: ±10% (matching specification)
• Dielectric type: Polypropylene (PP), Metallized (material compatibility)
• Mounting configuration: Through Hole, Radial package
• Termination style: PC Pins
• Lead spacing: 27.50 mm (PCB layout compatibility)

Secondary Compatibility Factors:

• Voltage rating: Equal to or greater than 800V DC
• Operating temperature range: Minimum -40°C to 100°C coverage
• RoHS compliance status

Two substitute parts meet these criteria with varying voltage ratings and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

MABA013680KHL (Nichicon) - Parametric Equivalent

The Nichicon MABA013680KHL provides direct parametric equivalence to the 684MABA01KHS. Both components share identical capacitance, tolerance, voltage ratings, dielectric material, operating temperature range, and physical dimensions. The MABA013680KHL is currently in active production status, ensuring supply chain availability. This part maintains the same 20.00 mm seated height and 11.00 mm width, confirming PCB layout compatibility without modification. Both components are ROHS3 compliant and REACH unaffected.

R474R368050A1K (KEMET) - Higher Voltage Rated Substitute

The KEMET R474R368050A1K functions as a substitute with elevated voltage specifications. This part maintains the 0.68 µF capacitance, ±10% tolerance, and polypropylene metallized dielectric. The 1000V DC rating exceeds the original 800V specification, providing additional voltage margin. The operating temperature range extends to 110°C, compared to 100°C for the original part. However, the R474R368050A1K exhibits increased physical dimensions: 14.00 mm width and 28.10 mm seated height versus 11.00 mm and 20.00 mm respectively. This dimensional difference requires PCB layout verification before implementation. The part carries AEC-Q200 and X1 ratings, indicating automotive qualification. Lead spacing remains compatible at 27.50 mm.

Selection Basis:

• For direct replacement without PCB modification: MABA013680KHL (Nichicon)
• For applications requiring higher voltage margin and automotive compliance: R474R368050A1K (KEMET), contingent on PCB layout accommodation

Both substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can the R474R368050A1K be used in place of the 684MABA01KHS without PCB modification?

A: The R474R368050A1K has identical lead spacing (27.50 mm) but differs in physical dimensions. The width increases from 11.00 mm to 14.00 mm, and seated height increases from 20.00 mm to 28.10 mm. PCB layout verification is required to confirm clearance around the component footprint before implementation.

Q: What is the primary difference between the two substitute parts?

A: The Nichicon MABA013680KHL provides parametric equivalence with matching voltage ratings (800V DC) and identical physical dimensions. The KEMET R474R368050A1K offers higher voltage rating (1000V DC) and extended temperature range (to 110°C) but requires larger PCB space allocation.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the MABA013680KHL and R474R368050A1K are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 684MABA01KHS.

Q: Why is the 684MABA01KHS listed as obsolete?

A: The original part is no longer in active production. The Nichicon MABA013680KHL and KEMET R474R368050A1K are active production alternatives that fulfill the same functional requirements.

Q: Can capacitance or tolerance values differ between the main part and substitutes?

A: No. All substitute parts must maintain the exact 0.68 µF capacitance and ±10% tolerance specification. Deviations in these parameters disqualify a part from substitution.

Q: What determines lead spacing compatibility?

A: Lead spacing of 27.50 mm is maintained across all three parts, ensuring PCB hole pattern compatibility. This parameter is fixed and non-negotiable for through-hole radial capacitor substitution.

Q: Is the polypropylene metallized dielectric material consistent across all parts?

A: Yes. All three components—684MABA01KHS, MABA013680KHL, and R474R368050A1K—utilize polypropylene (PP) metallized dielectric, ensuring electrical performance consistency in motor run applications.
