Product details

50-Position Dual-Row Breakaway Header at 2.54mm Pitch

The 4-103240-0-25: This is a 50-position, dual-row unshrouded header from the AMPMODU Mod II series — a standard TE modular interconnect family. All 50 positions are loaded, so the header delivers the full circuit count for a 50-conductor cable or backplane interface. The unshrouded push-pull fastening means the header mates without a locking latch — suitable for applications where the connector pair is not subject to continuous vibration or where intentional disconnection is frequent. The breakaway design allows snapping the header to shorter lengths if the full 50 positions are not needed, though this part ships as a fixed 50-position piece.

3 A per Contact with 30 µinch Gold Mating Surface

The post finish is tin-lead (100.0 µinch / 2.54 µm), which solders reliably into plated through-holes.

Frequently asked questions

How many positions does 4-103240-0-25 have?

50 positions in a dual-row arrangement, all loaded. The pitch is 0.100" (2.54mm) with the same row spacing.

Can 4-103240-0-25 replace a 50-pin header from another brand?

The 2.54mm pitch and dual-row layout are industry-standard, so it is footprint-compatible with many 50-pin receptacles. However, the unshrouded push-pull design and 3 A rating should be verified against the original part's specifications.

What is the closest pin-compatible alternative to 4-103240-0-25 in the AMPMODU Mod II family?

No official cross-reference or alternative part number is listed. The base product number 103240 identifies the series; other position counts in the same family share the same pitch and contact design but differ in circuit count.
