TE Connectivity AMP Connectors 535651-1 PCMCIA Card Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 535651-1 is a 68-position PCMCIA card connector designed for surface mount, right-angle applications. This connector features a push-in, pull-out insertion method with gold-plated contacts and board guide functionality. The part is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing circuit board layouts and connector interfaces.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 535651-1 PCMCIA connector are identified based on strict equivalence of the following critical parameters:

• Card Type: PCMCIA (68-position standard)
• Number of Positions: 68
• Mounting Type: Surface Mount, Right Angle
• Insertion, Removal Method: Push In, Pull Out
• Height Above Board: 0.275" (6.99mm)
• Contact Finish: Gold at 30.0µin (0.76µm) thickness
• Mounting Feature: Normal, Standard - Top

The substitute part 5535651-1 maintains all electrical and mechanical parameters identical to the main part. The primary distinction is product status: the substitute is active and RoHS3 compliant, whereas the main part is obsolete and RoHS non-compliant. Both parts share the same base connector architecture and are functionally interchangeable in PCMCIA card slot applications.

Parameter Comparison

Engineering Selection Recommendations

The 535651-1 is classified as obsolete and is RoHS non-compliant. For new designs and production applications, the 5535651-1 substitute part is the appropriate selection. This substitute maintains full electrical and mechanical compatibility while offering the following advantages:

• Active Product Status: The 5535651-1 is an active product with ongoing manufacturer support and availability.
• RoHS3 Compliance: The substitute meets RoHS3 regulatory requirements, eliminating compliance barriers for applications subject to environmental regulations.
• Enhanced Features: The substitute includes both board guide and card guide features, compared to board guide only in the main part. This enhancement provides improved mechanical stability during card insertion and removal cycles.
• Identical Electrical Performance: All critical electrical parameters, including contact finish, contact finish thickness, and insertion method, remain unchanged.
• Packaging Availability: The substitute is available in bulk packaging with confirmed inventory.

For legacy systems currently using the 535651-1, the 5535651-1 provides direct substitution without circuit board redesign or connector interface modification.

Frequently Asked Questions (FAQ)

Q: Can the 5535651-1 substitute directly replace the 535651-1 in existing designs?

A: Yes. The 5535651-1 maintains identical electrical and mechanical specifications for all critical parameters: 68-position PCMCIA configuration, surface mount right-angle mounting, 0.275" (6.99mm) height above board, gold contact finish at 30.0µin thickness, and push-in/pull-out insertion method. Direct substitution is possible without circuit board layout modification.

Q: What is the difference between the board guide and card guide features?

A: The main part 535651-1 includes board guide functionality. The substitute 5535651-1 includes both board guide and card guide features. The card guide provides additional mechanical support for the PCMCIA card during insertion and removal operations. This enhancement does not affect electrical compatibility or physical mounting dimensions.

Q: Why is the 535651-1 classified as obsolete?

A: The 535651-1 is obsolete due to its RoHS non-compliant status and the availability of the active equivalent 5535651-1. Manufacturers typically transition obsolete parts to active alternatives that meet current regulatory requirements.

Q: Are there any packaging differences between the main part and substitute?

A: The main part 535651-1 packaging information is not specified in the available data. The substitute 5535651-1 is supplied in bulk packaging. Confirm packaging requirements with the component supplier for specific application needs.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the 535651-1 and 5535651-1 have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or soldering processes.

Q: Are both parts subject to export control regulations?

A: Both parts are classified under ECCN EAR99, which is the standard export control classification for most commercial electronic components. Verify current export regulations with appropriate authorities for specific jurisdictions.
