92140-010LF PCMCIA Card Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 92140-010LF is a 68-position PCMCIA card connector featuring push-pull insertion and right-angle through-hole mounting with gold-plated contacts and integrated card guides. This connector is classified as obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity. TE Connectivity AMP Connectors offers multiple active alternatives that maintain functional compatibility with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for PCMCIA card connectors is determined by the following critical parameters:

• Card Type: Must be PCMCIA (all substitutes meet this requirement)
• Number of Positions: Must be 68 (all substitutes meet this requirement)
• Insertion, Removal Method: Must be Push In, Pull Out (all substitutes meet this requirement)
• Mounting Type: Must be Through Hole, Right Angle (all substitutes meet this requirement)
• Contact Finish: Must be Gold (all substitutes meet this requirement)

All four substitute parts from TE Connectivity AMP Connectors satisfy these core electrical and mechanical compatibility criteria. Variations in height above board and contact finish thickness do not prevent functional substitution but may require PCB layout verification depending on application constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5535653-2

This part maintains the card guide feature present in the original 92140-010LF, ensuring mechanical alignment consistency. It carries active product status with ROHS3 compliance and provides higher contact finish thickness (30.0µin) compared to the original specification, enhancing durability and contact reliability. Height above board of 0.275" (6.99mm) represents a minimal increase from the original 0.228" (5.80mm) and is within typical PCB layout tolerances for PCMCIA applications.

Secondary Substitute: 5178431-1

This part offers the lowest height above board among active alternatives at 0.280" (7.10mm), making it suitable for space-constrained applications. It includes card guides and maintains RoHS compliance with active product status. Contact finish thickness of 11.8µin provides intermediate durability between the original and other alternatives.

Alternative Substitutes: 5535653-1 and 5535655-1

Both parts are active with ROHS3 compliance and higher contact finish thickness. 5535653-1 omits card guides and matches the height of 5535653-2 at 0.275" (6.99mm). 5535655-1 provides the highest profile at 0.378" (9.60mm) and lacks card guides, suitable only for applications where increased clearance is available and card guide functionality is not required.

Frequently Asked Questions (FAQ)

Q: Can 5535655-1 be used as a direct replacement for 92140-010LF?

A: 5535655-1 meets all core electrical and mechanical compatibility criteria (68 positions, PCMCIA type, push-pull insertion, through-hole right-angle mounting, gold contacts). However, its height above board of 0.378" (9.60mm) is significantly greater than the original 0.228" (5.80mm), and it lacks card guides. PCB layout verification is required before selection.

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

A: Contact finish thickness affects contact durability and wear resistance. The original 92140-010LF specifies 3.00µin (0.076µm), while all TE Connectivity substitutes provide 11.8µin to 30.0µin. Higher thickness values extend contact life under repeated insertion cycles and improve corrosion resistance, representing an enhancement over the original specification.

Q: Are all substitutes RoHS compliant?

A: Yes. The original 92140-010LF is RoHS Compliant. All four substitute parts meet RoHS requirements: 5178431-1 is RoHS Compliant, while 5535653-1, 5535653-2, and 5535655-1 are ROHS3 Compliant, indicating compliance with the most current RoHS directive.

Q: Does the absence of card guides in 5535653-1 and 5535655-1 affect compatibility?

A: Card guides provide mechanical alignment assistance during card insertion. The original 92140-010LF includes this feature. Substitutes with card guides (5178431-1 and 5535653-2) maintain this functionality. Substitutes without card guides (5535653-1 and 5535655-1) rely on connector body alignment alone and are suitable only for applications where card guide functionality is not required by design.

Q: What is the MSL rating and why is it relevant?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard conditions without special moisture control measures, simplifying supply chain management and storage requirements.
