15-24-4441 Connector: Specs, Failure Rates & Sourcing Tips
Introduction: Distributor listings and datasheets consistently describe the 15-24-4441 connector as a 4-position, 5.08 mm (0.200") pitch right-angle through‑hole power header commonly found on disk-drive power interfaces and industrial PCBs. Catalog frequency and cross-reference entries signal steady demand and broad availability; procurement records often show it as a stocked, cross‑referenced power header.
Purpose & Promise: This guide delivers a concise specifications breakdown, evidence‑based failure and reliability guidance, and practical sourcing tips so engineers and buyers can evaluate, design with, and procure this part reliably.
Background: Identification & Usage
Engineers need a compact checklist to identify the part in inventory lists or on PCBs. Typical datasheets and distributor pages list pitch, row count, orientation, and tail type as primary identifiers.
Physical Identification Checklist
- ● 4 positions, single row, 5.08 mm (0.200") pitch
- ● Right‑angle orientation with through‑hole solder tails
- ● PCB footprint: 5.08 mm center‑to‑center tail spacing
- ● Mounting peg locations and row offset for seating

Reliability & Failure Mode Analysis
Field returns frequently report issues linked to mechanical stress and environmental exposure. Understanding these helps in proactive mitigation.
-
!
Contact Fatigue: Plating loss from repeated mating cycles.
-
!
Solder Joint Stress: Vibration or mechanical leverage on right-angle tails.
-
!
Corrosion: Resistance increases in humid or salty environments.

PCB & Design Best Practices
- Use reinforced pads and follow recommended annular ring sizes.
- Include mounting pegs to carry shear loads.
- Provide strain relief for mating cables to prevent solder stress.
- Ensure adequate solder fillet access during layout.
Inspection & Test Procedures
- Continuity and contact resistance checks on every lot.
- Visual inspection against the manufacturer drawing.
- Thermal cycle profiles for harsh environment deployments.
- Mechanical push/pull sampling to verify retention.
Sourcing & Procurement Strategy
Validate authenticity by requiring full lot traceability and RoHS/REACH declarations. For long lead-time seasons, employ a stocking strategy and qualify equivalents early.
