Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 206971-2 with the active TE Connectivity 5745355-4 is based on equivalence across the following critical parameters:

Functional Equivalence Parameters:

• Connector style, type, and pin configuration (D-Sub plug, male pins, 50 positions, 3 rows)
• Shell size and layout (5 DD, D)
• Mounting configuration (through hole, right angle)
• Termination method (solder)
• Electrical ratings (6A current, 125V voltage)
• Operating temperature range (-55°C ~ 105°C)
• Contact material and finish (brass with gold plating)
• Flammability compliance (UL94 V-0)

Differences Noted: The 5745355-4 incorporates enhanced features including grounding indents, mounting brackets, and a mating side flange with standard 4-40 screws. The dielectric material differs (polyamide nylon glass-filled versus thermoplastic), and backset spacing varies (0.545" versus 0.590"). The substitute part maintains active product status with RoHS3 compliance, whereas the original is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5745355-4 serves as the direct active substitute for the obsolete 206971-2. Selection of the 5745355-4 is supported by the following engineering considerations:

Product Status: The 206971-2 is classified as obsolete, creating supply chain risk. The 5745355-4 maintains active product status with confirmed inventory availability (980 pcs), ensuring long-term procurement viability.

Regulatory Compliance: The 5745355-4 achieves RoHS3 compliance, whereas the 206971-2 is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the 5745355-4 fulfills regulatory obligations.

Functional Compatibility: Both connectors maintain identical electrical ratings (6A, 125V), operating temperature range (-55°C ~ 105°C), and core mechanical specifications (50-position, 3-row, shell size 5, right-angle solder termination). The connectors are functionally interchangeable within the AMPLIMITE HDP-20 series.

Physical Integration Considerations: The backset spacing difference (0.590" versus 0.545") and enhanced flange features (4-40 screws, grounding indents, mounting brackets) on the 5745355-4 require PCB layout verification to confirm mechanical fit within existing designs. The dielectric material change from thermoplastic to polyamide nylon glass-filled does not affect electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are the 206971-2 and 5745355-4 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical ratings (6A current, 125V voltage), operating temperature range (-55°C ~ 105°C), contact material (brass), and contact finish (gold). They are electrically equivalent within the AMPLIMITE HDP-20 series.

Q: What is the primary reason for substitution?

A: The 206971-2 is classified as obsolete, creating procurement challenges. The 5745355-4 is an active product with confirmed inventory, ensuring supply chain continuity and long-term availability.

Q: Does the 5745355-4 require PCB design modifications?

A: The backset spacing differs between the two connectors (0.590" for 206971-2 versus 0.545" for 5745355-4). Additionally, the 5745355-4 includes mounting brackets and 4-40 screw flanges not present on the 206971-2. PCB layout verification is necessary to confirm mechanical fit and mounting compatibility.

Q: What is the difference in dielectric material?

A: The 206971-2 uses thermoplastic dielectric material, while the 5745355-4 uses polyamide nylon glass-filled material. Both materials meet UL94 V-0 flammability requirements and do not affect electrical performance within the specified operating parameters.

Q: Is the 5745355-4 RoHS compliant?

A: Yes. The 5745355-4 is RoHS3 compliant, whereas the 206971-2 is RoHS non-compliant. For applications requiring RoHS compliance, the 5745355-4 fulfills regulatory requirements.

Q: What packaging is available for the 5745355-4?

A: The 5745355-4 is supplied in bulk packaging with 980 pcs available in new original stock.

Q: Are both connectors rated for the same temperature range?

A: Yes. Both the 206971-2 and 5745355-4 operate across the identical temperature range of -55°C to 105°C.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
