92140-505LF PCMCIA Card Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 92140-505LF is a 68-position PCMCIA card connector featuring push-pull insertion and right-angle through-hole mounting with gold-plated contacts. This connector is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and component procurement. The part is designed for memory card applications requiring reliable push-in/pull-out engagement with card guide features.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 92140-505LF are qualified based on the following critical parameters that must remain constant:

• Card Type: PCMCIA (68-position standard)
• Number of Positions: 68
• Insertion/Removal Method: Push In, Pull Out
• Mounting Type: Through Hole, Right Angle
• Contact Finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in height above board, mounting feature orientation, contact finish thickness, and compliance certifications are documented in the parameter comparison table to support design validation and procurement decisions.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain the core PCMCIA 68-position connector specification with push-pull engagement and through-hole right-angle mounting. Selection among substitutes should account for the following factors:

5178431-1: Active status with RoHS compliance. Height of 0.280" (7.10mm) represents a moderate increase from the original 0.228" (5.80mm). No card guides. Suitable for designs requiring modern compliance certifications.

5535653-1: Active status with ROHS3 compliance. Height of 0.275" (6.99mm) with increased contact finish thickness of 30.0µin. No card guides. Higher inventory availability (2608 pcs). Suitable for applications where enhanced contact durability is beneficial.

5535653-2: Active status with ROHS3 compliance. Identical height and contact finish to 5535653-1 at 0.275" (6.99mm) and 30.0µin respectively. Includes card guides matching the original design feature. Recommended for direct replacement where card guide functionality is required.

5535655-1: Active status with ROHS3 compliance. Height of 0.378" (9.60mm) represents the largest vertical profile. No card guides. Suitable only where increased board clearance is available and card guide functionality is not required.

All substitute parts are classified as active products with unlimited moisture sensitivity rating, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts directly replace the 92140-505LF without PCB modification?

A: 5535653-2 provides the closest functional match, maintaining card guide features and similar height profile (0.275" vs. 0.228"). However, the mounting feature differs (Normal, Standard - Top vs. Reverse - Bottom), requiring PCB layout verification. Other substitutes require height clearance validation due to increased board standoff distances.

Q: What is the significance of the mounting feature difference (Reverse - Bottom vs. Normal, Standard - Top)?

A: The original 92140-505LF uses reverse-bottom mounting, while all substitutes use normal-top mounting. This indicates different PCB footprint orientations and connector approach angles. Design validation is required to confirm compatibility with existing PCB layouts.

Q: Why do substitute parts have thicker gold contact finishes?

A: The substitute parts feature contact finish thicknesses of 11.8µin to 30.0µin compared to the original 3.00µin. Thicker finishes provide enhanced wear resistance and contact durability over extended insertion/removal cycles, representing an improvement in connector longevity.

Q: Are all substitute parts RoHS compliant?

A: Yes. 5178431-1 is RoHS Compliant, while 5535653-1, 5535653-2, and 5535655-1 are ROHS3 Compliant. The original 92140-505LF does not specify RoHS status. All substitutes meet current environmental compliance requirements.

Q: Which substitute part has the best inventory availability?

A: 5535653-1 has the highest inventory level at 2608 pcs new original stock, followed by 5535653-2 at 1054 pcs. Both are suitable for volume procurement requirements.

Q: Does the absence of card guides in some substitutes affect functionality?

A: Card guides provide mechanical alignment assistance during card insertion. 5535653-2 retains this feature. For applications where card guides are not critical to assembly or operation, 5178431-1, 5535653-1, and 5535655-1 are functionally equivalent. Design requirements should determine necessity.
