254mm PITCH DIL EXTENDED PCB TAIL PIN HEADER

Category: Connectors, Electronics, HARWIN

Harwin’s datasheet provides detailed information on their MZQ-960xxxX series of pin headers designed for PCB mounting. The datasheet covers specifications, material and finish details, electrical characteristics, mechanical durability, environmental parameters, recommended PCB mounting practices, and ordering information.

Specifications

The pin headers are made from high-temperature Nylon 6T, compliant with UL94V0 standards, and are available in black. The pins are constructed from brass, with two finish options available: 45 Gold and 46 100% Tin over nickel.

Electrical Characteristics

Current Rating: Contact resistance is specified at a maximum of 25 milliohms (Gold) and 30 milliohms (Tin).
Insulation Resistance: A minimum of 1000 megohms is maintained.
Dielectric Strength: 750V AC minimum.

Mechanical Durability

The connectors are rated for 300 operations with the Gold finish and 50 operations with the Tin finish.

Environmental Parameters

The temperature range for the components is given as -40°C to +105°C.

Mechanical Characteristics

The drawing outlines the pin headers’ 2.54mm pitch with different numbers of contacts per row, ranging from 02 to 40. A recommended PCB mounting hole size is specified at 1.0mm ±0.2mm, and all dimensions are provided in millimeters. A typical row distance is 2.54mm, with a square 0.64mm contact size and 5.08mm typical distance between rows.

Packaging

The pin headers are packaged in bags for delivery.

Ordering Information

For specific ordering, the datasheet provides the order code format M20-960XXXX, which includes the number of contacts per row.

Assembly Drawing and Confidentiality Notice

The assembly is shown in drawing number M20-960xxXX. Harwin asserts its confidentiality and copyright ownership of the drawing and any descriptive material contained within, prohibiting unauthorized use.

Contact Information

The datasheet concludes with contact information for Harwin’s offices in the USA, UK, and Asia, including telephone and fax numbers and email addresses for further support and inquiries.

The datasheet is the second page of a two-page document, as notated by “SHEET 2 OF 2”. It is important to note that the drawing is not to scale and is a third-angle projection with all dimensions given in millimeters. Specific tolerances for material, finish, angles, and surface areas are outlined apart from the other specifications. Furthermore, the notes advise checking the latest issue of the component specification for complete information.
