WTB90PR9SY

Headers, Male Pins Overview

The WTB90PR9SY is a rectangular MIL-DTL-55302 series connector plug manufactured by AirBorn, a Molex company. It features a 2-row configuration with 9 positions and utilizes gold-plated copper alloy pins for reliable signal transmission. Designed for board mount applications, this component employs a through-hole termination style and includes a right-angle installation orientation to facilitate compact circuit board layouts. The housing is constructed from Polyphenylene Sulfide (PPS), providing durability in demanding environments. Rated for 1 kV voltage and 5 A current, it operates within a temperature range of -65°C to +125°C, ensuring stability across extreme conditions.

Headers, Male Pins Procurement Notes

Verify the specific manufacturer part number against official AirBorn or Molex documentation to confirm compatibility with existing MIL-DTL-55302 designs. Ensure that the right-angle orientation and through-hole termination match the target PCB layout requirements. Cross-reference the RoHS compliance status if environmental regulations apply to the final assembly. Confirm that the 9-position count aligns with the intended circuit interface needs before procurement.

Headers, Male Pins Selection Notes

Select this component when a rigid, high-density connection is required for military-grade applications. The right-angle form factor is suitable for boards where vertical clearance is limited but horizontal routing is preferred. Consider the 2.54 mm pitch for standard spacing requirements. Evaluate the thermal rating of +125°C against the operational environment to ensure long-term reliability under heat stress without degrading the PPS housing integrity.

Headers, Male Pins Part Context

This connector belongs to the AirBorn W Series, a line of rectangular MIL-Spec connectors designed for harsh environments. The series is known for its robust construction and compliance with stringent military standards. As a product of AirBorn, now part of Molex, it benefits from advanced manufacturing capabilities while maintaining the heritage of high-performance interconnect solutions used in critical defense and aerospace sectors.

Headers, Male Pins Replacement Considerations

The part number alias M55302/57B30X indicates a cross-reference to the MIL-DTL-55302 specification. When substituting, verify that any alternative meets the same MIL-DTL-55302 type requirements. Ensure the replacement maintains the 9-position count, 2-row arrangement, and right-angle mounting style. Gold plating and PPS housing materials should be matched to preserve electrical and environmental performance characteristics.
