TE Connectivity 1-1734282-2 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-1734282-2 is a 15-position D-Sub stacked connector featuring both plug (male pins) and receptacle (female sockets) configurations in a right-angle, through-hole solder termination design. This connector is part of the AMPLIMITE HD-20 series and is classified as obsolete. The connector operates across a temperature range of -55°C to 105°C with a current rating of 1.5–3A and 250V voltage rating. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support, production continuity, and component sourcing.

Engineering Selection Recommendations

Primary Substitutes for Direct Replacement:

The Amphenol ICC L17H2340120, L17H2340121, and L17H2342120 connectors provide the closest functional equivalence to the TE Connectivity 1-1734282-2. These parts maintain identical connector geometry (15-position, 2-row D-Sub stacked), mounting configuration (through-hole, right-angle), and termination method (solder). All three Amphenol parts are active products with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The L17H2340120 and L17H2342120 feature housing/shell flange configuration matching the original part, while L17H2340121 includes mating-side female screwlock capability. Current ratings of 3A match the original specification, and voltage ratings of 250V are identical.

Secondary Substitutes with Enhanced Specifications:

The Assmann WSW A-DD 15 B-2 connector offers equivalent functionality with active product status and ROHS3 compliance. This part maintains through-hole right-angle solder termination and 250V voltage rating. The 3A current rating aligns with the original specification. The connector features board lock and grounding indents, providing enhanced mechanical stability.

Higher-Current Alternatives:

NorComp Inc. parts (178-015-413R491, 178-015-413R571, 178-015-413R691, 179-015-413R491, 179-015-413R571, 179-015-413R691) provide 5A current ratings, exceeding the original 1.5–3A specification. These parts are active products with ROHS3 compliance. The 178-series parts support panel mount and through-hole configurations, while the 179-series parts support board edge and through-hole configurations. All NorComp parts include board lock, grounding indents, and shielding features. Shell material is nickel-plated steel rather than tin-plated, and dielectric material is polyamide (PA9T) nylon 9T rather than thermoplastic.

Compliance and Availability:

All substitute parts are active products with current manufacturing status, ensuring ongoing availability. Amphenol and Assmann parts carry RoHS compliance certification. NorComp parts are ROHS3 compliant. All parts operate across the required -55°C to 105°C temperature range and maintain signal contact type classification.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 178-series and 179-series connectors with 5A current ratings replace the original 1.5–3A rated part?

A: Yes. The 5A current rating of NorComp parts exceeds the original specification and is compatible with applications designed for 1.5–3A operation. Higher current ratings provide additional design margin and do not create incompatibility with lower-current applications.

Q: What is the difference between Housing/Shell (4-40) and Mating Side, Female Screwlock (4-40) flange features?

A: Housing/Shell (4-40) flange features are located on the connector housing and use 4-40 threaded holes for panel mounting. Mating Side, Female Screwlock (4-40) features are located on the mating side of the connector and provide female screwlock capability for secure mating. Selection depends on the specific mounting and mating requirements of the application.

Q: Are Nickel-Plated and Tin-Plated shell finishes interchangeable?

A: Both finishes provide corrosion resistance and are suitable for signal-level D-Sub connectors. Nickel plating offers superior corrosion resistance in harsh environments, while tin plating is traditional for general-purpose applications. Selection should be based on environmental exposure and application requirements. Both finishes are compatible with gold-plated contacts.

Q: What is the significance of contact finish thickness (10.0µin vs. Flash)?

A: Contact finish thickness affects contact durability and mating cycle life. 10.0µin (0.25µm) represents a specific gold plating thickness, while Flash indicates a minimal gold coating applied for corrosion protection. Both are acceptable for signal-level applications. Flash plating is more economical and suitable for applications with moderate mating cycles, while thicker plating provides enhanced durability for high-cycle applications.

Q: Can I use a connector with Polyamide (PA9T) dielectric material in place of one with Thermoplastic dielectric?

A: Yes. Polyamide (PA9T) nylon 9T and thermoplastic materials both provide adequate dielectric properties for signal-level D-Sub connectors operating at 250V. Polyamide offers superior thermal stability and mechanical strength, making it suitable for demanding applications. Both materials operate across the required -55°C to 105°C temperature range.

Q: What is the difference between Through Hole, Panel Mount, and Board Edge mounting types?

A: Through Hole mounting allows the connector to be soldered directly to PCB vias. Panel Mount configuration includes a flange for mounting to a panel or enclosure. Board Edge mounting positions the connector at the edge of the PCB for external access. Selection depends on the physical layout and accessibility requirements of the application.

Q: Are all substitute parts available in the same packaging as the original?

A: The original TE Connectivity part does not specify packaging. Substitute parts are available in Tray packaging, which is standard for D-Sub connectors. Tray packaging provides protection during storage and handling while maintaining component accessibility.

Q: Do all substitute parts include Board Lock and Grounding Indents features?

A: Board Lock and Grounding Indents are included in most substitute parts (NorComp, Assmann, and Amphenol). These features enhance mechanical stability and provide grounding paths. The original TE Connectivity part includes Board Lock. Verify specific feature requirements for your application.

Q: What is the Backset Spacing parameter, and why does it vary?

A: Backset Spacing refers to the distance from the rear of the connector shell to the contact termination point. The original part does not specify this parameter. Substitute parts specify 0.318" (8.08mm) backset spacing where applicable. This parameter affects PCB layout and component clearance. Verify backset spacing compatibility with your PCB design.

Q: Are the substitute parts suitable for applications requiring RoHS compliance?

A: Yes. All substitute parts carry RoHS or ROHS3 compliance certification, making them suitable for applications subject to RoHS regulations. The original TE Connectivity part is marked as "Not applicable" for RoHS status due to its obsolete classification.
