What This Header Is
Ratings That Drive the Fit Decision
Pitch is the anchor: 0.100" (2.54mm) is the industry-standard 2.54mm grid, so the footprint matches virtually every dual-row header in this pitch class — a 32-circuit board layout can accept any 32-position or breakaway-cut subset of a compatible series. Row spacing matches the mating pitch at 0.100", keeping the two rows aligned to the standard dual-row receptacle footprint. Current rating is 5 A per contact — solid for signal duty and capable for low-power bus or LED driver rails. The voltage rating of 110V covers the vast majority of digital logic and instrumentation bus voltages; confirm the working voltage against your creepage requirements at the specific board spacing, not just the rating headline. The push-pull fastening type relies on the contact friction and header body geometry rather than a latch or locking tab — so the mated pair depends on the receptacle's retention feature for vibration security. Verify the mating half carries a positive-lock or friction-shoulder design if the assembly sees mechanical disturbance.
Environment and Application Fit
The -65°C to 130°C operating range is wide for a commodity header — it handles both cold-end industrial environments and elevated-temperature zones near heat sources or enclosed panels without derating concern at the connector itself. The UL94 V-0 rated thermoplastic housing meets the flammability floor for most industrial and instrumentation enclosures. Black insulation colour is standard for the series and carries no functional implication — the colour code is a production/brand marker, not a selection parameter. The unshrouded header exposes the pins on all four sides; factor pin protection into the enclosure design if the board is field-accessible or subject to handling.
Sourcing
Listed Active. The 75844 base product number maps to the BERGSTIK series family with no official successor or cross-reference identified. No compliance documentation (RoHS, REACH, UL, IEC) is called out in this listing's evidence — only the UL94 V-0 flammability rating is present. For industrial or instrumentation procurement requiring REACH or RoHS declarations, request the manufacturer compliance data sheet directly against the order code before finalising the BOM.
