TE Connectivity 1-1740199-2 D-Sub Plug 25P SMD Right Angle Solder Connector

Part Overview

The TE Connectivity 1-1740199-2 is a 25-position D-Sub plug connector with surface mount, right angle termination and solder attachment. This connector belongs to the AMPLIMITE HD-20 series and features male pins in a 2-row configuration with shell size 3 (DB, B) layout. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, maintenance, and production continuity. The connector is constructed with a steel shell finished in tin plate, gold-plated contacts, and a glass-filled polycyclohexylenedimethylene terephthalate (PCT) dielectric material rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1740199-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 25
• Number of rows: 2
• Shell size and layout: 3 (DB, B)
• Mounting type: Surface Mount, Right Angle
• Termination method: Solder
• Contact type: Signal
• Flange feature: Housing/Shell (4-40)
• Contact finish: Gold
• Contact finish thickness: 31.5µin (0.80µm)
• Dielectric material: Polycyclohexylenedimethylene Terephthalate (PCT), Glass Filled
• Operating temperature range: -55°C ~ 105°C
• Material flammability rating: UL94 V-0
• RoHS compliance: RoHS Compliant
• Moisture sensitivity level: 1 (Unlimited)
• Series: AMPLIMITE HD-20

Allowable Variation Parameters:

The substitute part 1-1740199-5 maintains all mandatory parameters while differing only in shell finish (nickel plated versus tin plated) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-1740199-5 serves as a direct functional equivalent to the obsolete 1-1740199-2. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including pin count, shell size, mounting configuration, and termination method.

The primary distinction between these parts is the shell finish material: the main part features tin plating while the substitute features nickel plating. Both finishes provide equivalent corrosion resistance and contact reliability for signal-level D-Sub applications within the specified operating temperature range of -55°C to 105°C.

The 1-1740199-5 carries active product status, ensuring ongoing availability and manufacturing support. Both parts maintain RoHS compliance and unlimited moisture sensitivity level (MSL 1), suitable for standard storage and handling conditions without special precautions.

For applications requiring the obsolete 1-1740199-2, the 1-1740199-5 provides full functional interchangeability with no design modifications required. The nickel-plated shell of the substitute part offers equivalent performance characteristics to the tin-plated original in standard industrial and commercial environments.

Frequently Asked Questions (FAQ)

Q: Can the 1-1740199-5 directly replace the 1-1740199-2 in existing designs?

A: Yes. The 1-1740199-5 maintains identical specifications across all functional parameters including connector type, pin configuration, mounting style, and termination method. The only difference is the shell finish material (nickel plated versus tin plated), which does not affect electrical or mechanical compatibility.

Q: What is the significance of the shell finish difference between these parts?

A: The main part features a steel shell with tin plating, while the substitute features a steel shell with nickel plating. Both finishes provide corrosion protection and contact reliability. The choice between tin and nickel plating does not impact performance in standard operating environments within the specified temperature range.

Q: Why is the 1-1740199-2 classified as obsolete?

A: The 1-1740199-2 is listed as obsolete, indicating it is no longer in active production. The 1-1740199-5, which is active, provides equivalent functionality and serves as the current production alternative.

Q: Are there any packaging differences between these connectors?

A: The main part packaging is not specified in the documentation. The substitute part 1-1740199-5 is supplied in bulk packaging. Packaging differences do not affect connector performance or compatibility.

Q: What compliance certifications apply to both parts?

A: Both connectors are RoHS compliant and carry UL94 V-0 material flammability rating. Both maintain moisture sensitivity level 1 (unlimited), indicating no special storage or handling requirements.

Q: Are these connectors suitable for high-temperature applications?

A: Both connectors operate within the temperature range of -55°C to 105°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the contact finish specification for these connectors?

A: Both connectors feature gold-plated contacts with a thickness of 31.5µin (0.80µm), providing reliable signal transmission and contact durability.
