Weidmüller 1007720000 BL 3.50/10/90 SN SW BX PRT PCB Plug Technical Guide

The Weidmüller 1007720000 BL 3.50/10/90 SN SW BX PRT PCB plug connector belongs to the same compact pluggable PCB connection family used for modular wiring in industrial electronics. This part number is particularly relevant in documentation, maintenance, and replacement analysis because it combines a mature board connector format with a clearly stated lifecycle note. For engineers searching legacy BOMs or trying to understand equipment already in the field, that is often just as important as current electrical data.

This item is listed as a female PCB plug with 3.50 mm pitch, 10 poles, 90° orientation, and clamping yoke connection, with conductor acceptance up to 1.5 mm². The available product information also shows that this product is discontinued. That lifecycle detail should shape how it is evaluated in new versus existing designs.

What the Part Does

The Weidmüller 1007720000 PCB female plug is designed for board-to-wire connections where removability, compactness, and organized wiring are valuable. In industrial control products, a connector like this allows wiring to be terminated into a pluggable interface rather than being permanently fixed directly to the board. That can simplify both manufacturing and repair.

When a device has multiple signal paths or low-power circuits that need to be grouped into one connector position, a 10-pole PCB plug is a logical format. It supports cleaner interconnection design and faster service compared with one-wire-at-a-time re-termination on the board itself.

Technical Construction and Ratings

The mechanical format follows a compact 3.50 mm pitch, which is often selected when PCB space is limited but the connection still needs to remain practical for assembly. The 90-degree cable exit supports enclosure-friendly routing and can help reduce overall device depth or improve strain path planning.

The published series data for this family includes IEC current values up to 12 A depending on pole count and ambient condition, plus rated voltages up to 320 V based on surge voltage class and pollution degree. Material details include PBT insulation, black housing color, UL 94 V-0, and tinned Cu-alloy contacts, which are all meaningful indicators for practical industrial use.

Why the Discontinued Status Matters

The most important planning issue around the Weidmüller 1007720000 BL 3.50/10/90 connector is its lifecycle status. Because it is explicitly marked as discontinued, engineering teams should not treat it like a standard active-choice part for new development without further supply chain verification. Instead, it is better understood as a part number that remains highly useful for service, documentation, maintenance planning, and exact replacement analysis in existing equipment.

In many industrial organizations, that is a real need. Machines often remain in service for years beyond initial production. During that time, discontinued connector references still matter for spare part mapping, repair documentation, and modernization roadmaps.

Best Context for This Part Number

The Weidmüller 1007720000 female PCB plug is best suited to legacy equipment support, engineering documentation, retrofit planning, and controlled replacement work where the exact mechanical family matters. It also remains a useful reference point for finding compatible or successor connector solutions in the wider Weidmüller PCB portfolio.

FAQ

What is the Weidmüller 1007720000?

It is a female PCB plug connector with 3.50 mm pitch, 10 poles, and a 90° orientation, intended for pluggable board-level wiring.

Is the Weidmüller 1007720000 still available as an active product?

The available product information marks this part as discontinued. That means it should be reviewed carefully before being specified into any new design.

What type of connection technology does it use?

It uses a clamping yoke connection, which is a familiar and serviceable wire termination approach in PCB connector families.

What is the maximum conductor size?

The product description lists a maximum clamping range of 1.5 mm².

Why would this part still matter if it is discontinued?

Discontinued parts remain important in maintenance, spare part planning, retrofit projects, and legacy BOM validation. In many industrial environments, accurate replacement knowledge is essential.

How should engineers handle this part in a new design?

They should first verify lifecycle strategy, available stock, and possible successor products. In most new projects, an active equivalent is generally the safer long-term choice.
