Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 85863-902 is determined by the following critical parameters:

• Connector Type & Configuration: Receptacle with female sockets, 30 positions, 5-row arrangement
• Pitch Specification: 0.079" (2.00mm) center-to-center spacing
• Mounting & Termination: Board edge mounting with right-angle through-hole solder termination
• Electrical Ratings: Voltage and current handling capacity
• Environmental Compliance: Flammability rating and operating temperature range
• Physical Features: Board guide and spacer provisions

The TE Connectivity AMP Connectors part number 223004-1 meets the core mechanical and electrical substitution criteria for the 85863-902, sharing identical position count, pitch, mounting configuration, and termination method.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 223004-1 serves as a functional substitute for the obsolete Amphenol ICC 85863-902 based on mechanical and physical compatibility. Both connectors share identical position count, pitch, mounting configuration, and solder termination method, enabling direct board-level replacement.

The 223004-1 offers the advantage of active product status, ensuring ongoing availability and manufacturer support. The extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) provides additional thermal margin for applications requiring higher temperature operation.

Voltage rating differences exist between the two parts: the 85863-902 is rated for 1000V while the 223004-1 is rated for 30V. Application voltage requirements must be evaluated to determine suitability. The 223004-1 includes gold contact finish, which may provide improved contact reliability compared to unspecified contact finish on the original part.

Both connectors maintain UL94 V-0 flammability compliance. The 223004-1 is subject to REACH regulations, whereas the 85863-902 is REACH unaffected. RoHS non-compliance applies to both parts.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 223004-1 directly replace the Amphenol ICC 85863-902 on existing PCBs?

A: Yes, mechanical and electrical compatibility is established through matching position count (30), pitch (0.079"), mounting type (board edge, right angle), and termination method (solder). PCB footprints designed for the 85863-902 will accommodate the 223004-1 without modification.

Q: What is the significance of the voltage rating difference between these connectors?

A: The 85863-902 is rated for 1000V operation, while the 223004-1 is rated for 30V. Selection must be based on the actual voltage requirements of the application. If the system operates above 30V, the 223004-1 may not be suitable.

Q: Why does the 223004-1 have a higher maximum operating temperature?

A: The 223004-1 supports operation to 125°C compared to 105°C for the 85863-902. This extended range reflects the design specifications of the TE Connectivity Z-PACK series and may provide additional thermal margin for applications in elevated-temperature environments.

Q: What is the difference between the contact finishes?

A: The 85863-902 contact finish is not specified in the available documentation. The 223004-1 features gold-plated contacts, which typically provide enhanced corrosion resistance and contact reliability compared to unspecified finishes.

Q: Are there any compliance differences between these parts?

A: Both connectors are RoHS non-compliant and maintain UL94 V-0 flammability ratings. The 223004-1 is subject to REACH regulations, while the 85863-902 is REACH unaffected. Applications subject to REACH compliance requirements should account for this distinction.

Q: What packaging is available for the substitute part?

A: The TE Connectivity 223004-1 is supplied in tube packaging, whereas packaging information for the 85863-902 was not specified.
