Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 40P4.6-JMCS-G-TF(N) is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 40 positions, 2-row arrangement, plug type with outer shroud contacts
• Electrical Interface: 0.020" (0.50mm) pitch contact spacing
• Physical Form Factor: Surface mount package with 4.6mm mated stacking height
• Material Specification: Gold contact finish for signal integrity and corrosion resistance
• Environmental Compliance: RoHS compliance and MSL rating of 1

The identified substitute part 145046040635868+ from KYOCERA AVX meets all these criteria, providing functional and mechanical interchangeability for the obsolete JST component.
