TE Connectivity 749806-1 D-Sub 9-Position Receptacle Connector
Part Overview
The TE Connectivity 749806-1 is a 9-position D-Sub receptacle connector with female sockets, designed for crimp termination in the AMPLIMITE HDP-20 series. This connector features a shielded steel shell with tin plating, gold-flashed contacts, and operates across a temperature range of -55°C to 105°C with a 250V voltage rating.
The 749806-1 carries an obsolete product status. Locating equivalent substitute components is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or field replacement requirements.

Substitute Part Grouping Explanation
The TE Connectivity 749806-7 qualifies as a direct substitute for the 749806-1 based on strict electrical and mechanical parameter equivalence. Both connectors share identical specifications across all critical substitution criteria:
Key Parameters Determining Substitution:
- Connector style, type, and position count (D-Sub, 9-position receptacle, female sockets)
- Shell size and layout (Size 1, DE/E configuration)
- Mounting method (Free Hanging, In-Line)
- Termination technology (Crimp)
- Shell material and finish (Steel, Tin Plated)
- Contact material and finish (Phosphor Bronze, Gold Flash)
- Voltage and temperature ratings (250V, -55°C to 105°C)
- Flange configuration (Cable Side, Male Short Screw 4-40)
- Shielding and dielectric properties (Shielded, Polyamide/Nylon Glass Filled)
- Flammability compliance (UL94 V-0)
The 749806-7 differs only in product status (Active versus Obsolete) and RoHS compliance status, with no impact on functional or mechanical compatibility.

Engineering Selection Recommendations
The TE Connectivity 749806-7 is the direct functional equivalent of the 749806-1 and is suitable for substitution in all applications requiring a 9-position D-Sub receptacle connector with the specified electrical and mechanical characteristics.
Product Status Consideration: The 749806-1 is classified as obsolete, while the 749806-7 maintains active product status. Selection of the 749806-7 ensures continued availability and support from the manufacturer.
Compliance Consideration: The 749806-7 carries RoHS Compliant certification, whereas the 749806-1 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use the 749806-7. For applications without RoHS mandates, both parts remain functionally equivalent.
Electrical and Mechanical Equivalence: All critical parameters—connector geometry, contact configuration, termination method, material composition, voltage rating, temperature range, and shielding—are identical between the two parts. No design modifications or re-qualification are required for substitution.
Frequently Asked Questions (FAQ)
Q: Can the 749806-7 be used as a direct replacement for the 749806-1 in existing designs?
A: Yes. The 749806-7 is electrically and mechanically equivalent to the 749806-1 across all specified parameters. No design changes are required for substitution.
Q: What is the primary difference between these two part numbers?
A: The 749806-1 is obsolete with RoHS non-compliant status, while the 749806-7 is an active product with RoHS Compliant certification. All functional and mechanical specifications are identical.
Q: Are there any compatibility issues with existing cable assemblies or mating connectors?
A: No. Both connectors share identical shell size (Size 1, DE/E), pin configuration (9-position, 2-row), mounting style (Free Hanging, In-Line), and flange design (Cable Side, Male Short Screw 4-40). They are fully compatible with the same mating components.
Q: Does the RoHS compliance difference affect electrical performance?
A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts maintain identical voltage rating (250V), temperature range (-55°C to 105°C), and contact specifications.
Q: What is the packaging difference between these parts?
A: The 749806-1 packaging is not specified in available documentation. The 749806-7 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.
Q: Are both parts suitable for shielded applications?
A: Yes. Both the 749806-1 and 749806-7 feature shielded construction with steel, tin-plated shells and are rated for 250V operation with UL94 V-0 flammability compliance.
Q: Can these connectors be used in high-temperature environments?
A: Yes. Both connectors operate across the temperature range of -55°C to 105°C, supporting applications in industrial and harsh environment settings.
