Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5146029-1 is determined by the following critical parameters that must remain constant across equivalent parts:

Core Functional Parameters:

• Card Type: PCMCIA (68-position standard)
• Number of Positions: 68
• Connector Type: Connector and Ejector assembly
• Insertion/Removal Method: Push In, Push Out mechanism
• Ejector Side: Left
• Mounting Type: Through Hole, Right Angle configuration
• Contact Finish: Gold plating
• Mounting Feature: Normal, Standard - Top

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4040

The substitute part 74443-100CA satisfies all core functional requirements and environmental classifications. Variations in height above board and contact finish thickness do not preclude substitution when mechanical envelope constraints permit the alternative dimension.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC (FCI) 74443-100CA

The 74443-100CA is the qualified equivalent for the obsolete 5146029-1. This substitute maintains functional parity across all critical PCMCIA connector parameters including 68-position configuration, push-in/push-out ejection, right-angle through-hole mounting, and gold contact finish.

Product Status Consideration: The 74443-100CA carries active product status, ensuring ongoing availability and manufacturing support. The 5146029-1 is classified as obsolete, making transition to an active equivalent necessary for new production and long-term supply chain continuity.

Compliance Status: The 5146029-1 is RoHS3 compliant. The 74443-100CA is RoHS non-compliant. Design teams must evaluate regulatory requirements for their specific application before selecting this substitute. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Mechanical Envelope: The 74443-100CA has a reduced height above board of 0.228" (5.80mm) compared to the 5146029-1 at 0.550" (13.97mm). This dimensional difference must be verified against PCB layout and mechanical clearance requirements before implementation.

Contact Enhancement: The 74443-100CA features GXT™ contact finish technology, which provides enhanced contact performance characteristics beyond standard gold plating. This enhancement does not compromise compatibility with standard PCMCIA card interfaces.

Frequently Asked Questions (FAQ)

Q: Can the 74443-100CA directly replace the 5146029-1 in existing designs?

A: The 74443-100CA is functionally equivalent for PCMCIA card connector applications. However, the reduced height above board (0.228" versus 0.550") requires verification of mechanical clearance in the existing PCB layout. RoHS compliance status differs between the two parts and must be evaluated against application requirements.

Q: What is the significance of the GXT™ contact finish on the 74443-100CA?

A: GXT™ is an enhanced gold plating technology that improves contact durability and performance. It is compatible with standard PCMCIA card interfaces and does not introduce incompatibility with existing card designs.

Q: Are there any electrical performance differences between these connectors?

A: Both connectors are 68-position PCMCIA card connectors with identical electrical specifications for contact count, insertion/removal method, and signal integrity requirements. Electrical performance is equivalent for standard PCMCIA applications.

Q: Why is the RoHS compliance status different between the two parts?

A: The 5146029-1 was manufactured to RoHS3 specifications, while the 74443-100CA is RoHS non-compliant. This reflects different manufacturing timelines and regulatory requirements at the time of production. Applications subject to RoHS regulations must confirm compliance requirements before substitution.

Q: What is the packaging difference between these parts?

A: The 5146029-1 packaging specification is not provided in the technical data. The 74443-100CA is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both connectors rated for the same moisture sensitivity level?

A: Yes. Both the 5146029-1 and 74443-100CA are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly.

Q: What inventory status should be considered for procurement planning?

A: The 5146029-1 has 751 pieces in stock as new original inventory. The 74443-100CA has 731 pieces in stock as new original inventory. Both parts are currently available, though the 5146029-1 is obsolete and future availability is not guaranteed.
