What This Poke-In Receptacle Does in the Assembly
The Molex 0521510510 is a 5-position, single-row receptacle from the Series 52151 family, designed for poke-in termination of 26 AWG solid wire. The 2.00 mm cable pitch matches the board-side pitch, so the wire-to-board routing stays aligned. Its closed-end housing stops the stripped wire from pushing through the back of the connector during insertion — a practical detail when you are seating wire by hand on a harness board.
Press-Fit, Right-Angle, No Solder
Press-fit assembly avoids the thermal cycle of reflow or wave solder, so the board sees no heat stress at this connector location.
Poke-In Termination — No Crimp Terminal Needed
Cable termination is poke-in: strip the 26 AWG solid wire to the specified length, push it into the contact cavity, and the internal spring grips the conductor. There is no separate crimp terminal to source and no crimp tool to qualify — just the wire and the connector.
This part is listed as Active on the lifecycle record. There is no last-time-buy notice, no phase-out date, and no official successor order code. The 0521510510 can be specified into a BOM without planning for an end-of-life migration. Sourcing is through independent distribution; availability is confirmed at quote time against the RFQ quantity.
