Engineering Selection Recommendations

Both the MKS2D021501A00KSSD and B32529C1153K000 are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on:

Inventory availability: MKS2D021501A00KSSD has 4189 units in stock; B32529C1153K000 has 2914 units in stock
Manufacturer preference: WIMA versus EPCOS - TDK Electronics
Supply chain considerations and lead times
Cost and volume pricing structures

Both components carry AEC-Q200 automotive qualification and ROHS3 compliance, making them suitable for automotive circuit applications without additional qualification requirements. The stacked radial construction noted for the EPCOS part does not alter electrical performance or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can B32529C1153K000 be used as a direct replacement for MKS2D021501A00KSSD?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.015 µF), tolerance (±10%), voltage ratings (100V DC / 63V AC), dielectric material (polyester metallized), operating temperature range (-55°C ~ 125°C), physical dimensions, lead spacing, and termination type. Both carry AEC-Q200 and ROHS3 compliance.

Q: Are there any physical differences between these parts?

A: Both components share identical external dimensions (0.283" L x 0.098" W, 0.256" height, 0.197" lead spacing) and radial through-hole mounting configuration. The internal construction difference (stacked radial for EPCOS) does not affect PCB layout or mechanical fit.

Q: What compliance certifications apply to both parts?

A: Both the MKS2D021501A00KSSD and B32529C1153K000 meet AEC-Q200 automotive qualification standards and are ROHS3 compliant. Both are REACH unaffected and classified under ECCN EAR99.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. Both components are rated for automotive applications with AEC-Q200 qualification. Electrical and mechanical specifications are identical, supporting direct substitution in automotive circuit designs.

Q: What is the lead spacing requirement for PCB layout?

A: Both parts require 0.197" (5.00mm) lead spacing for through-hole mounting. PCB footprints designed for either component are compatible with both.
