TE Connectivity AMP Connectors 749798-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 749798-1 is a 15-position D-Sub high-density plug connector with male pins, designed for through-hole solder termination. This connector belongs to the AMPLIMITE HD-22 series and features a steel nickel-plated shell with gold-plated contacts. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing applications requiring D-Sub high-density connectivity in 15-position configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the TE Connectivity 749798-1 is based on strict electrical and mechanical parameter alignment within the D-Sub high-density connector category. The following parameters establish substitution eligibility:

Core Matching Parameters:

• Connector style: D-Sub, High Density
• Connector type: Plug, Male Pins
• Number of positions: 15
• Number of rows: 3
• Shell size and layout: 1 (DE, E) High Density
• Termination method: Solder
• Contact material: Brass
• Shell material finish: Steel, Nickel Plated
• Contact finish: Gold
• Flammability rating: UL94 V-0

The substitute part NorComp Inc. 180-015-113R011 meets all core matching parameters. Variations in current rating, voltage rating specification, operating temperature range, mounting type options, and RoHS compliance status are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

The NorComp Inc. 180-015-113R011 serves as a functional substitute for the obsolete TE Connectivity 749798-1 based on matching core connector specifications: D-Sub high-density configuration, 15-position plug with male pins, 3-row layout, solder termination, and identical shell and contact materials with gold plating.

Compliance Considerations:

The substitute part 180-015-113R011 holds active product status and ROHS3 compliance certification, whereas the original 749798-1 is obsolete and RoHS non-compliant. Applications subject to RoHS regulatory requirements must utilize the substitute part.

Performance Differences:

The substitute part provides higher current rating capacity (3A versus 1.5A) and includes shielding features in addition to grounding indents. Operating temperature range differs slightly (-50°C ~ 100°C for substitute versus -55°C ~ 105°C for original). Voltage rating is not specified for the substitute part, whereas the original is rated at 125V.

Mounting Configuration:

The substitute part supports both panel mount and through-hole mounting options, providing additional installation flexibility compared to the original through-hole-only configuration.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 180-015-113R011 directly replace the TE Connectivity 749798-1 in existing applications?

A: The NorComp 180-015-113R011 matches all core D-Sub high-density connector specifications including position count, row configuration, shell size, termination method, and contact materials. Direct mechanical and electrical compatibility is established for applications operating within the substitute part's specified parameters.

Q: What are the key differences between these two connectors?

A: Primary differences include product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), current rating capacity (1.5A versus 3A), operating temperature range (-55°C to 105°C versus -50°C to 100°C), mounting options (through-hole only versus panel mount and through-hole), and shielding features (grounding indents only versus grounding indents and shielded).

Q: Does the higher current rating of the substitute part affect compatibility?

A: The substitute part's 3A current rating exceeds the original 1.5A specification. This higher capacity does not create incompatibility; applications designed for 1.5A operation remain compatible with the substitute part.

Q: What is the significance of the shielding feature in the substitute part?

A: The NorComp 180-015-113R011 includes shielding in addition to grounding indents. This feature provides enhanced electromagnetic interference (EMI) rejection compared to the original part's grounding indents alone.

Q: Are there packaging differences between these parts?

A: The TE Connectivity 749798-1 packaging information is not specified in available data. The NorComp 180-015-113R011 is supplied in tray packaging.

Q: How do the operating temperature ranges compare?

A: The original TE Connectivity part operates from -55°C to 105°C. The substitute NorComp part operates from -50°C to 100°C. Applications requiring operation below -50°C or above 100°C must evaluate compatibility against specific environmental requirements.

Q: Is voltage rating a critical factor in selecting the substitute?

A: The original part is rated at 125V. The substitute part does not specify a voltage rating in available documentation. Applications with specific voltage requirements must confirm compatibility with the substitute part's electrical specifications.
