3M 3626-7624 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 3626-7624 is a 24-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector operates as a free-hanging, in-line component with gold-plated female socket contacts rated for 26-28 AWG wire gauges. The part is active in production and RoHS compliant, making it suitable for applications requiring reliable ribbon cable interconnection in industrial and commercial environments. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement requirements necessitate alternative manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the 3M 3626-7624 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

  • Connector Type & Position Count: Receptacle configuration with 24 positions
  • Pitch & Row Configuration: 0.100" (2.54mm) pitch with 2-row layout and 0.100" row spacing
  • Cable Termination Method: IDC termination for ribbon cable
  • Wire Gauge Compatibility: 26-28 AWG support
  • Contact Finish: Gold plating for corrosion resistance and electrical performance
  • Mounting Configuration: Free hanging, in-line orientation
  • Compliance Standards: RoHS compliance and MSL rating

The TE Connectivity AMP Connectors part 1658621-5 meets all critical substitution criteria. While minor variations exist in contact type (forked vs. female socket), contact finish thickness, and packaging format, these differences do not affect the core electrical and mechanical interface requirements for ribbon cable IDC applications.

Engineering Selection Recommendations

Both the 3M 3626-7624 and TE Connectivity 1658621-5 are active production parts with equivalent compliance certifications. The 3M part carries standard RoHS compliance, while the TE Connectivity substitute meets ROHS3 compliance, representing an enhanced regulatory standard. Both parts maintain MSL rating 1 (unlimited moisture sensitivity level) and share identical ECCN and HTSUS classifications, confirming their equivalence for export and tariff purposes.

Selection between these parts should be based on availability, lead time, packaging requirements (bulk vs. tube), and procurement preferences. The TE Connectivity part offers higher inventory availability (1700 pcs vs. 1185 pcs) and tube packaging, which may provide advantages for automated assembly processes. The 3M part is available in bulk packaging, suitable for manual assembly or custom kit configurations.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1658621-5 directly replace the 3M 3626-7624 in existing designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (24), row configuration (2 rows with 0.100" spacing), cable termination method (IDC), and wire gauge support (26-28 AWG). The mechanical and electrical interfaces are fully compatible for ribbon cable applications.

Q: What is the difference between female socket and forked contact types?

A: Both contact types are designed for IDC termination and provide equivalent electrical performance in this application. The contact type variation does not affect compatibility with standard ribbon cable connectors or mating components.

Q: Does the difference in contact finish thickness affect performance?

A: The 3M part specifies 30.0µin (0.76µm) gold plating, while the TE Connectivity part specifies 15.0µin (0.38µm). Both thicknesses meet industry standards for gold-plated contacts in IDC applications and provide adequate corrosion resistance and electrical conductivity for this connector category.

Q: What is the significance of the packaging difference (bulk vs. tube)?

A: Bulk packaging is suitable for manual assembly and custom configurations. Tube packaging is optimized for automated pick-and-place assembly systems. The choice depends on manufacturing process requirements and assembly methodology, not on connector functionality.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are active production components with RoHS compliance and MSL rating 1. The TE Connectivity part carries enhanced ROHS3 compliance. Both are suitable for industrial and commercial applications requiring reliable ribbon cable interconnection. Application-specific reliability requirements should be evaluated against detailed electrical and environmental specifications.

Q: Can these connectors be used interchangeably with other 24-position IDC connectors?

A: Compatibility depends on matching all critical parameters: pitch (0.100"), row configuration (2 rows with 0.100" spacing), cable termination method (IDC), and wire gauge support (26-28 AWG). Connectors from different manufacturers with identical specifications are mechanically and electrically interchangeable.
