M24308/24-3F D-Sub 25 Position Plug Connector Equivalent & Substitute Parts
Part Overview
The M24308/24-3F is a 25 position D-Sub plug connector manufactured by ITT Cannon, LLC, designed for panel mount, through-hole solder termination applications. This connector features male pins in a 2-row configuration with shell size 3 (DB, B) layout. The part is currently active in production with 699 units in stock.
Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, including position count, shell size, termination method, and current rating compatibility. Alternative sources provide equivalent functionality while accommodating different mounting configurations, flange designs, and compliance certifications.

Engineering Selection Recommendations
Current Rating Alignment: Parts 09663216701 and 09663216702 maintain the 7.5A current rating of the M24308/24-3F, providing direct electrical equivalence. All other HARTING substitutes operate at 6.5A, which is acceptable for signal-level D-Sub applications but represents a 13% reduction in current capacity.
Temperature Operating Range: The M24308/24-3F operates to 150°C. All HARTING substitutes are rated to 125°C maximum, representing a 25°C reduction in upper temperature limit. Applications requiring operation above 125°C require the original ITT Cannon part.
Compliance Considerations: The M24308/24-3F is RoHS non-compliant. All HARTING substitutes are ROHS3 compliant, meeting current environmental regulations. Selection depends on system-level compliance requirements.
Flange Configuration: M3 flange variants (09653216701, 09653217701, 09653616711, 09653696711, 09663216701) and 4-40 flange variants (09653216702, 09653217702, 09653616712, 09653617712, 09663216702) accommodate different PCB mounting hole patterns. Unthreaded housing of the M24308/24-3F requires panel-mount installation without threaded fastening.
Contact Finish: Part 09653696711 provides gold contact finish matching the M24308/24-3F specification. Remaining HARTING parts do not specify contact finish, which may affect corrosion resistance in high-humidity or marine environments.
Frequently Asked Questions (FAQ)
Q: Can HARTING parts with 6.5A rating replace the 7.5A M24308/24-3F? A: Yes, for signal-level applications. The 6.5A rating is acceptable for D-Sub connectors carrying signal rather than power. If the application requires the full 7.5A capacity, use 09663216701 or 09663216702.
Q: What is the difference between M3 and 4-40 flange variants? A: Flange feature refers to the mounting hole pattern on the connector shell. M3 variants use metric M3 threaded holes; 4-40 variants use imperial 4-40 threaded holes. Selection depends on PCB design and available mounting hardware.
Q: Are HARTING substitutes compatible with existing M24308/24-3F sockets? A: Yes. All substitute parts maintain the 25 position, shell size 3 (DB, B) configuration, ensuring mechanical and electrical compatibility with mating D-Sub receptacles designed for the M24308/24-3F.
Q: Does the 25°C reduction in maximum operating temperature affect my application? A: Applications operating continuously above 125°C require the M24308/24-3F. For applications with maximum operating temperature at or below 125°C, HARTING substitutes are suitable.
Q: What packaging options are available? A: The M24308/24-3F is supplied in bulk packaging. HARTING substitutes are available in bulk (most variants) or tray packaging (09653616712). Packaging selection affects handling and storage but does not affect electrical or mechanical performance.
Q: Why would I choose a non-compliant part over ROHS3 compliant alternatives? A: Legacy system designs or applications with existing non-compliant component inventories may require the M24308/24-3F for consistency. New designs should prioritize ROHS3 compliant HARTING alternatives.
