Product details

The TE Connectivity 1-1658621-0 is the 50-position member of the AMP-Latch series, a dual-row IDC receptacle designed for mass-termination of 26-28 AWG ribbon cable. The polarizing key and feed-through feature prevent mis-mating and allow daisy-chaining through the cable, which is common in parallel bus or signal distribution layouts.

Sizing the Wire and the Tooling

This receptacle accepts 26-28 AWG ribbon cable — the IDC slot geometry is sized for those gauges. Heavier or lighter cable will not terminate reliably; the insulation thickness and conductor diameter have to land within the fork's bite range. The standard tool for AMP-Latch mass termination is a hand press or arbor press with the correct die set (TE part number 58073-1 or equivalent), which drives all 50 contacts simultaneously. No solder, no individual crimp — the termination is mechanical and gas-tight when done with the right tool.

How the 50-Position Receptacle Compares to Other AMP-Latch Options

The 1-1658621-0's 50 positions serve a denser cable assembly — the 17-position part is for narrower bus widths.

Frequently asked questions

Where can I buy the 1-1658621-0 and what is the lead time?

Lead time depends on the quantity and the lot source, but we provide that detail with each quote.

Is the 1-1658621-0 RoHS compliant and lead-free?

Yes, the 1-1658621-0 is ROHS3 compliant, covering all restricted substances including lead, mercury, cadmium, and phthalates — no exemptions apply.

What wire gauge and tooling does the 1-1658621-0 require?

The receptacle accepts 26-28 AWG ribbon cable only. Termination is IDC — use a hand or arbor press with the correct AMP-Latch die set (TE 58073-1 or equivalent) to terminate all 50 contacts in one stroke.

What is the difference between the 1-1658621-0 and the 1-226733-4?

The 1-1658621-0 has 50 positions with forked contacts, while the 1-226733-4 has 17 positions with female socket contacts and a detent lock. Both are 0.100" pitch IDC receptacles for ribbon cable — the choice depends on circuit count and whether the detent lock is needed for vibration resistance.
