1. Dimensional Variance: The XLC-60-H-MA measures 136.0 mm in length, while the XLC-60-H-MAS is 176.0 mm—a 40 mm reduction in the MA variant. This shorter form factor offers greater spatial flexibility, making it more suitable for compact designs. However, the reduced housing length may decrease internal heat dissipation area. Although both parts share the same rated operating temperature range, the thermal stability of the MA version under continuous full-load conditions should be validated in actual application environments. 2. Cost Difference: The unit price of the XLC-60-H-MA is higher, likely reflecting the use of more compact component layouts or newer device technologies to achieve miniaturization, which in turn raises manufacturing costs. In volume applications, this cost differential should be taken into consideration.
