• Insertion, Removal Method: Push In, Pull Out
• Mounting Type: Surface Mount
• Height Above Board: 0.551" (14.00mm)
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Features: Board Guide
• Mounting Feature: Normal, Standard - Top

The substitute part 5146733-1 maintains full electrical and mechanical compatibility with the original 146733-1 across all specified parameters. Both parts are manufactured by TE Connectivity AMP Connectors and share identical functional specifications for PCMCIA card connector applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 5146733-1

The 5146733-1 is a direct functional equivalent to the 146733-1 across all electrical and mechanical parameters. Both parts are obsolete PCMCIA card connectors with identical 68-position configurations, surface mount mounting, and gold contact specifications.

Compliance Consideration:

The 5146733-1 carries ROHS3 compliance status, whereas the original 146733-1 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 5146733-1 provides compliance alignment while maintaining full electrical and mechanical compatibility.

Packaging Difference:

The 5146733-1 is supplied in tube packaging, whereas the original part number does not specify packaging format. This difference does not affect functional compatibility but may influence procurement, handling, and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can the 5146733-1 be used as a direct replacement for the 146733-1 in existing designs?

A: Yes. The 5146733-1 maintains identical electrical and mechanical specifications across all critical parameters including position count, insertion method, mounting type, height above board, contact finish, and board guide features. Both parts are 68-position PCMCIA surface mount connectors with gold-plated contacts.

Q: What is the difference between the 146733-1 and 5146733-1?

A: The primary differences are RoHS compliance status and packaging format. The 5146733-1 is ROHS3 compliant while the 146733-1 is RoHS non-compliant. The 5146733-1 is supplied in tube packaging. All functional and electrical specifications remain identical.

Q: Are there inventory considerations when selecting between these parts?

A: The 5146733-1 has higher current inventory availability (1427 pieces) compared to the 146733-1 (718 pieces). Both are listed as new original stock.

Q: Does the tube packaging of the 5146733-1 affect its performance?

A: No. Packaging format does not affect connector performance, electrical characteristics, or mechanical compatibility. Packaging differences relate only to handling, storage, and procurement logistics.

Q: Why are both parts classified as obsolete?

A: Both the 146733-1 and 5146733-1 are obsolete PCMCIA card connectors. PCMCIA technology has been superseded by modern memory and interface standards. These parts remain available for legacy system support and repair applications.

Q: Can the 5146733-1 be used in new product designs?

A: The 5146733-1 is functionally equivalent to the 146733-1 and maintains all specified electrical and mechanical parameters. However, both parts are classified as obsolete. Design decisions should account for long-term component availability and the obsolescence status of PCMCIA connector technology.
