Key Parameters

Substitute Part Grouping Explanation

Substitution of the 749111-9 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type: D-Type Plug with male pins
• Number of positions: 120
• Number of rows: 2
• Shell size and pitch: 0.050 Pitch x 0.100 Row to Row
• Current rating: 1A
• Voltage rating: 30V
• Contact material: Phosphor Bronze
• Contact finish: Gold

Mechanical Compatibility Parameters:

• Mounting type: Free Hanging (In-Line)
• Termination method: IDC, Ribbon Cable
• Shell material and finish: Steel, Tin-Nickel Plated
• Shielded configuration

Environmental and Compliance Parameters:

• Operating temperature range: -55°C ~ 105°C
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must maintain identical specifications across all these parameters to ensure functional and mechanical compatibility with existing systems and mating connectors.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5749111-9 is the direct substitute for the obsolete 749111-9 connector. Both parts maintain identical electrical, mechanical, and environmental specifications across all critical parameters including connector configuration, pin count, pitch, termination method, and operating temperature range.

The primary distinction between the main part and substitute is product status and regulatory compliance. The 749111-9 is classified as obsolete and carries RoHS non-compliant status, while the 5749111-9 is in active production and RoHS compliant. For new designs and ongoing system support, the 5749111-9 is the appropriate selection as it provides equivalent functionality with current manufacturing support and improved environmental compliance.

Both connectors are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE .050 III series and are fully interchangeable in applications requiring 120-position D-Type plug connectors with IDC ribbon cable termination, 1A current rating, and 30V voltage rating.

Frequently Asked Questions (FAQ)

Q: Can the 5749111-9 directly replace the 749111-9 in existing applications?

A: Yes. The 5749111-9 is a direct equivalent substitute. All electrical, mechanical, and environmental parameters are identical, including connector type, pin count, pitch, termination method, current and voltage ratings, and operating temperature range. The connectors are fully interchangeable.

Q: What is the primary reason to transition from 749111-9 to 5749111-9?

A: The 749111-9 is obsolete and no longer in production. The 5749111-9 is the active production equivalent that provides the same functionality with current manufacturing support and RoHS compliance.

Q: Are there any differences in physical dimensions or mating characteristics?

A: No. Both connectors share identical shell size, connector layout (0.050 Pitch x 0.100 Row to Row), mounting type (Free Hanging In-Line), and mating interface specifications. They are mechanically and electrically interchangeable.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance status does not affect electrical or mechanical compatibility. The 5749111-9 offers improved environmental compliance while maintaining identical performance characteristics. Both connectors use the same materials and construction methods for the functional interface.

Q: What termination methods are supported by both connectors?

A: Both the 749111-9 and 5749111-9 support IDC (Insulation Displacement Contact) termination for ribbon cable applications. The termination method is identical between the two parts.

Q: Are there any inventory or lead time considerations?

A: The 749111-9 is obsolete with limited remaining inventory. The 5749111-9 is in active production and represents the current standard for this connector type, ensuring availability and consistent lead times for new orders.

Q: What is the current rating and voltage specification for these connectors?

A: Both connectors are rated for 1A current and 30V voltage. These specifications are identical and apply to all 120 positions within the connector.

Q: What is the operating temperature range for these D-Type connectors?

A: Both the 749111-9 and 5749111-9 operate across the temperature range of -55°C to 105°C, providing performance across industrial and extended environmental conditions.
