Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1103308-6 is determined by the following critical parameters:

Functional Compatibility Parameters:

• Connector Type: Hood configuration
• Style: Top Entry
• Size: 7-cavity
• Lock Mechanism: Dual locking clips on hood

Mechanical Compatibility Parameters:

• Housing Material: Aluminum die-cast construction
• Housing Color: Gray
• Dimensional envelope: Approximately 82.00mm L x 56.00mm W x 75-77mm H
• Thread Interface: PG21 or equivalent metric thread (M32)

Regulatory & Environmental Parameters:

• RoHS Compliance: ROHS3 or equivalent RoHS standard
• MSL Rating: 1 (Unlimited moisture sensitivity)
• ECCN Classification: EAR99

The Weidmüller 1788010000 qualifies as a substitute based on matching connector type, style, size, locking mechanism, housing material, color, and regulatory compliance. The thread size difference (M32 versus PG21) represents a mechanical interface variation that must be evaluated within the specific application context, as both are standard industrial thread specifications for heavy duty connectors in this size class.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1788010000 is an active substitute for the obsolete TE Connectivity 1-1103308-6. Both parts share identical connector architecture, cavity size, locking mechanism, and housing material specifications. The primary distinction is the thread interface: the TE Connectivity part uses PG21 thread, while the Weidmüller part uses M32 thread. Both are standard industrial thread specifications for this connector class.

Selection of the Weidmüller 1788010000 is supported by:

• Active product status, ensuring ongoing availability and manufacturer support
• RoHS compliance certification, meeting current regulatory requirements
• Identical MSL rating, confirming equivalent moisture handling characteristics
• Matching ECCN classification, maintaining export control consistency
• IP65 ingress protection rating, providing enhanced environmental sealing compared to the original part

The height dimension difference of 2mm (77mm versus 75mm) falls within typical manufacturing tolerances for die-cast aluminum connectors and does not affect functional compatibility in standard mounting applications.

Frequently Asked Questions (FAQ)

Q: What makes the Weidmüller 1788010000 a suitable substitute for the TE Connectivity 1-1103308-6?

A: Both connectors share the same functional architecture: hood-style top entry configuration, 7-cavity size, dual locking clips on the hood, and aluminum die-cast gray housing. Both meet RoHS compliance and carry identical MSL ratings. The primary interface difference is the thread specification (M32 versus PG21), which are equivalent metric and ISO thread standards for this connector class.

Q: Does the thread size difference between PG21 and M32 affect compatibility?

A: PG21 and M32 are both standard industrial thread specifications used in heavy duty connector applications. The choice between them depends on the specific panel or enclosure mounting interface. M32 is the metric equivalent specification. Compatibility is determined by the mounting interface requirements of the application, not by connector functional performance.

Q: Are there any dimensional concerns when substituting the Weidmüller part?

A: The Weidmüller 1788010000 is 2mm taller (77mm versus 75mm) than the original TE Connectivity part. This minor difference is within standard manufacturing tolerances for die-cast aluminum connectors and does not affect functional compatibility in typical mounting configurations. Verify clearance in space-constrained applications.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 refers to the third iteration of the Restriction of Hazardous Substances directive. The Weidmüller part carries general RoHS compliance, which meets current regulatory requirements. Both certifications confirm restriction of hazardous materials in the connector construction.

Q: Does the Weidmüller part offer any performance advantages?

A: The Weidmüller 1788010000 includes an IP65 ingress protection rating (dust tight, water resistant), which is not specified for the original TE Connectivity part. This provides enhanced environmental sealing capability. Both parts maintain identical MSL ratings and regulatory classifications.

Q: Is the Weidmüller part available in the same packaging as the original?

A: The Weidmüller 1788010000 is supplied in bulk packaging, whereas the original TE Connectivity part packaging is not specified. Verify packaging requirements for your procurement and inventory management processes.

Q: Can I use the Weidmüller part as a direct replacement without any modifications?

A: The Weidmüller 1788010000 is mechanically and functionally compatible with the TE Connectivity 1-1103308-6 for applications using M32 thread mounting interfaces. If your application requires PG21 thread, an adapter or alternative mounting solution may be necessary. Verify thread compatibility with your specific mounting interface before implementation.
