Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 749805-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 749805-7 maintains identical specifications in the following critical areas:

Connector configuration (9-position D-Sub plug with male pins), shell size and layout (Size 1, DE/E), mounting method (free-hanging in-line), termination technology (crimp), shell construction (steel with tin plating), contact material and finish (brass with gold flash), voltage rating (250V), operating temperature range (-55°C to 105°C), and wire gauge compatibility (20-24 AWG). Both parts belong to the AMPLIMITE HDP-20 series and share identical flange features (cable side, male short screw 4-40), dielectric material (polyamide nylon, glass-filled), and material flammability rating (UL94 V-0).

The primary distinction between these parts is product status and compliance certification. The 749805-1 is obsolete and RoHS non-compliant, while the 749805-7 is active and ROHS3 compliant, making it the appropriate selection for new designs and applications requiring current regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 749805-7 is the direct functional equivalent and recommended substitute for the obsolete 749805-1. Both connectors are electrically and mechanically identical across all specified parameters, ensuring drop-in compatibility in existing applications.

Selection of the 749805-7 is required for new product designs and applications subject to RoHS3 compliance requirements. The 749805-7 maintains active product status with TE Connectivity, ensuring continued availability, technical support, and supply chain reliability. The 749805-1, classified as obsolete, presents supply chain risk and does not meet current regulatory compliance standards.

For legacy systems currently utilizing the 749805-1, the 749805-7 provides a compliant replacement without requiring design modifications, as all electrical ratings, mechanical dimensions, and termination specifications remain unchanged.

Frequently Asked Questions (FAQ)

Q: Are the 749805-1 and 749805-7 electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications including 250V voltage rating, operating temperature range of -55°C to 105°C, wire gauge compatibility (20-24 AWG), and contact material composition (brass with gold flash finish). They are electrically interchangeable in all applications.

Q: Are the 749805-1 and 749805-7 mechanically interchangeable?

A: Yes. Both connectors feature identical mechanical specifications: 9-position D-Sub plug configuration, Size 1 (DE/E) shell layout, free-hanging in-line mounting, cable-side male short screw flange (4-40), crimp termination, and tin-plated steel shell construction. No design modifications are required for mechanical substitution.

Q: What is the primary difference between these two parts?

A: The primary differences are product status and regulatory compliance. The 749805-1 is obsolete and RoHS non-compliant, while the 749805-7 is active and ROHS3 compliant. The 749805-7 is the current production equivalent.

Q: Can the 749805-7 be used as a direct replacement in existing assemblies?

A: Yes. The 749805-7 is a direct replacement for the 749805-1 in all existing applications. No circuit modifications, PCB redesign, or assembly process changes are required.

Q: Why should new designs use the 749805-7 instead of the 749805-1?

A: New designs should use the 749805-7 because it is an active product with current manufacturing support, meets ROHS3 compliance requirements, and ensures long-term supply chain availability. The 749805-1 is obsolete and presents supply continuity risk.

Q: Are there packaging differences between the 749805-1 and 749805-7?

A: The 749805-1 packaging is not specified in the technical data. The 749805-7 is supplied in bulk packaging. Contact the manufacturer for specific packaging requirements for the 749805-1 if needed for legacy applications.

Q: Do both connectors support the same wire gauge range?

A: Yes. Both the 749805-1 and 749805-7 support wire gauges of 20-24 AWG, ensuring compatibility with identical cable specifications.

Q: Are the flange features identical on both connectors?

A: Yes. Both connectors feature cable-side male short screw flanges with 4-40 screw specifications, ensuring identical mounting and fastening compatibility.
