Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XF3M19151B is determined by strict parametric equivalence across all critical dimensions and electrical characteristics. The following parameters must match identically for a part to function as a direct substitute:

• 19-position connector configuration
• 0.5mm (0.020") pitch spacing
• Surface mount, right-angle orientation
• Top and bottom contact arrangement
• Solder termination method
• 0.30mm FFC/FCB thickness tolerance
• 2.00mm height above board
• Rotary lock and backlock mechanisms
• Tapered cable end type
• Copper alloy contacts with gold flash finish
• Halogen-free LCP housing and actuator materials
• 50V voltage rating
• 0.5A current rating
• -30°C to 85°C operating temperature range
• UL94 V-0 flammability classification
• 20 mating cycle rating
• MSL 1 moisture sensitivity level

Parameter Comparison

Engineering Selection Recommendations

The XF3M-1915-1B is a direct parametric equivalent to the XF3M19151B across all critical electrical, mechanical, and material specifications. All 20 core functional parameters match identically, confirming functional interchangeability.

The primary distinction is product status: XF3M19151B is obsolete while XF3M-1915-1B is active. The substitute part is RoHS compliant and available in Tape & Reel packaging, providing improved supply chain continuity and compliance with current environmental regulations. The substitute part maintains identical performance characteristics, ratings, and material composition.

Selection of XF3M-1915-1B is appropriate for new designs, production continuity, and replacement applications where the obsolete XF3M19151B is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Are XF3M19151B and XF3M-1915-1B mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 19-position configuration, 0.5mm pitch, surface mount right-angle orientation, 2.00mm height above board, and tapered cable end type. PCB footprints and mating interfaces are identical.

Q: Are the electrical ratings identical?
