Amphenol ICC 92856-540 PCMCIA Card Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 92856-540 is a 68-position PCMCIA card connector designed for Type I, II, and III applications with through-hole, right-angle mounting and push-pull insertion/removal mechanism. This connector features card guides and gold-plated contacts for reliable signal transmission in memory card applications.

The 92856-540 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for legacy systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 92856-540 are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Number of Positions: 68 (exact match required)
• Card Type: PCMCIA (standard compliance required)
• Insertion/Removal Method: Push In, Pull Out (mechanical interface requirement)
• Mounting Type: Through Hole, Right Angle (PCB integration requirement)
• Contact Finish: Gold (electrical performance and corrosion resistance)
• Features: Card Guides (mechanical alignment requirement)

The TE Connectivity AMP Connectors 5178431-1 meets all critical substitution criteria. It maintains the same 68-position configuration, PCMCIA card compatibility, push-pull mechanism, through-hole right-angle mounting, gold contact finish, and card guide features. Variations in height above board and contact finish thickness do not prevent functional substitution within standard PCMCIA applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5178431-1 is the primary substitute for the obsolete Amphenol ICC 92856-540. Both connectors share identical critical functional parameters: 68-position configuration, PCMCIA card type support, push-pull insertion mechanism, through-hole right-angle mounting, gold contact finish, and card guide features.

The TE Connectivity part offers the advantage of active product status, ensuring ongoing availability and supply chain support. Additionally, the 5178431-1 is RoHS compliant, meeting current environmental and regulatory requirements, whereas the 92856-540 is RoHS non-compliant.

The TE Connectivity part features increased contact finish thickness (11.8µin versus 3.94µin), which provides enhanced durability and contact reliability. The height above board difference (0.280" versus 0.307") is within typical PCB design tolerances for right-angle connectors and does not prevent functional substitution in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5178431-1 directly replace the Amphenol ICC 92856-540 in existing designs?

A: Yes. Both connectors maintain identical 68-position PCMCIA card compatibility, push-pull insertion/removal mechanism, through-hole right-angle mounting, gold contact finish, and card guide features. The minor height difference (0.280" versus 0.307") falls within standard PCB design tolerances for this connector class.

Q: What is the significance of the contact finish thickness difference?

A: The TE Connectivity part features 11.8µin (0.30µm) contact finish thickness compared to 3.94µin (0.10µm) on the Amphenol part. Increased thickness provides enhanced durability, improved contact reliability, and extended connector lifespan under repeated insertion/removal cycles.

Q: Why is RoHS compliance important for this substitution?

A: The TE Connectivity 5178431-1 is RoHS compliant, meeting current environmental regulations and industry standards. The Amphenol 92856-540 is RoHS non-compliant. For new designs or systems requiring regulatory compliance, the TE Connectivity part is the appropriate choice.

Q: Are there any mounting or PCB layout considerations when substituting these connectors?

A: Both connectors use through-hole, right-angle mounting. The 0.027" (0.70mm) height difference may require minor PCB layout verification to ensure adequate clearance in confined spaces. Standard PCMCIA connector footprints accommodate both parts without modification.

Q: What is the current availability status of these parts?

A: The Amphenol ICC 92856-540 is obsolete with limited inventory. The TE Connectivity 5178431-1 is active with established supply chain availability, making it the recommended long-term solution for component procurement.
