• Number of positions: 40
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Latch Lock/Eject Hooks, Short
• Contact shape: Square
• Contact finish thickness - mating: 30.0µin (0.76µm)
• Material flammability rating: UL94 V-0
• Product status: Active
• Moisture sensitivity level: 1 (Unlimited)

These parameters define the mechanical and electrical interface compatibility required for direct substitution in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 65863-203 and TE Connectivity 5499374-9 maintain active product status and share identical mechanical interface specifications. The TE Connectivity 5499374-9 offers RoHS compliance, whereas the Amphenol ICC 65863-203 is RoHS non-compliant. Both connectors carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating suitability for standard storage and handling conditions without special precautions.

The TE Connectivity 5499374-9 provides documented operating temperature range (-65°C ~ 105°C), current rating (1A per contact), and voltage rating (250VAC), whereas these electrical parameters are not specified for the Amphenol ICC 65863-203. The TE Connectivity part includes a mounting flange feature not present in the Amphenol ICC design.

Selection between these parts should be based on regulatory compliance requirements, supply chain availability, and specific application electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5499374-9 directly replace the Amphenol ICC 65863-203 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"/2.54mm), position count (40), row configuration (2 rows), shrouding type (4-wall), and fastening mechanism (latch lock/eject hooks, short). The mechanical interface is fully compatible for board-to-cable/wire applications.

Q: What are the differences in contact dimensions between these parts?

A: The TE Connectivity 5499374-9 has a mating contact length of 0.240" (6.10mm) compared to 0.230" (5.84mm) for the Amphenol ICC 65863-203. Post contact length differs by 0.005" (0.13mm). The TE Connectivity part has a lower insulation height of 0.549" (13.94mm) versus 0.640" (16.26mm) for the Amphenol ICC part.

Q: What is the significance of the RoHS compliance difference?

A: The TE Connectivity 5499374-9 is RoHS compliant, while the Amphenol ICC 65863-203 is RoHS non-compliant. RoHS compliance is mandatory for products sold into European Union markets and many other regulated regions. Selection depends on end-market regulatory requirements.

Q: Are the contact finish specifications equivalent?

A: Both parts specify 30.0µin (0.76µm) contact finish thickness on the mating surface. The Amphenol ICC 65863-203 uses gold or gold GXT™ finish, while the TE Connectivity 5499374-9 uses gold or gold-palladium finish. Both finishes provide equivalent corrosion resistance and electrical performance for standard applications.

Q: What packaging format is used for both parts?

A: Both the Amphenol ICC 65863-203 and TE Connectivity 5499374-9 are supplied in tray packaging, suitable for automated assembly and manual handling in production environments.

Q: Does the TE Connectivity part include additional features?

A: The TE Connectivity 5499374-9 includes a mounting flange feature not present in the Amphenol ICC 65863-203. This flange provides additional mechanical support and positioning capability in board-mounted applications.
