Product details

Modular Jack, 4p4c, Cat3 — SMT Vertical Mount

The Molex 0955036451 is a 4p4c modular jack from the 95503 series, using the RJ9/RJ10/RJ22 form factor for handset cords and low-speed data links. It is rated Cat3, which limits the signal path to voice and 10BASE-T Ethernet — not suitable for Cat5e or higher data rates. The jack is unshielded and does not contain an LED, keeping the footprint clean for basic connectivity.

SMT Retention and Board Fit

Contacts are gold flash over copper alloy — the flash plating handles the moderate mating cycle count of a handset jack without excessive cost. Single-port, single-row configuration.

Frequently asked questions

Is Molex 0955036451 shielded or unshielded?

The 0955036451 is unshielded — no metal shell or EMI gasket. For applications requiring shielding, look at the shielded variants in the 95503 series.

Is 0955036451 compatible with Cat5e?

No — the jack is rated Cat3, which supports voice and 10BASE-T only. Cat5e or higher data rates require a Cat5e-rated jack with tighter crosstalk and return loss specs.

Does Molex 0955036451 include an LED?

No LED — the jack is a straight pass-through without status indication.
