Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5205859-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Connector type (Plug, Male Pins)
• Number of positions (37)
• Number of rows (2)
• Shell size and layout (4, DC, C)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Current rating (6A)
• Voltage rating (125V)
• Operating temperature range (-55°C ~ 105°C)
• Contact material (Brass)
• Contact finish (Gold, Flash)
• Shell material and finish (Steel, Yellow Chromate Plated Zinc)
• Backset spacing (0.545" / 13.84mm)
• Flange feature (Mating Side, Standard Screws 4-40)
• Flammability rating (UL94 V-0)
• Moisture sensitivity level (1, Unlimited)

Parts meeting these criteria are classified as parametric equivalents and may be used interchangeably in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5205859-1 and 205859-1 are parametric equivalents across all critical electrical and mechanical specifications. Both connectors maintain identical performance characteristics for connector type, pin configuration, shell size, mounting method, current and voltage ratings, operating temperature range, contact materials, and physical dimensions.

The primary distinction between these parts relates to regulatory compliance status. The 5205859-1 carries RoHS Compliant certification with Vendor Undefined REACH status, while the 205859-1 is RoHS non-compliant and REACH Affected. Additionally, the dielectric material differs: the 5205859-1 uses Polyamide (PA) Nylon Glass Filled, whereas the 205859-1 uses Thermoplastic material.

For applications subject to RoHS regulations or requiring RoHS-compliant components, the 5205859-1 is the appropriate selection. For applications without RoHS compliance requirements, the 205859-1 provides functional equivalence. Component selection should align with the regulatory framework and material specifications applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 205859-1 be used as a direct replacement for the 5205859-1 in all applications?

A: The 205859-1 is a parametric equivalent across all electrical and mechanical specifications. However, regulatory compliance differs. The 5205859-1 is RoHS Compliant, while the 205859-1 is RoHS non-compliant. Selection depends on whether the application requires RoHS compliance.

Q: What is the significance of the dielectric material difference between these parts?

A: The 5205859-1 uses Polyamide (PA) Nylon Glass Filled dielectric material, while the 205859-1 uses Thermoplastic. Both materials meet the UL94 V-0 flammability rating. The material difference may affect mechanical properties and environmental resistance, but both maintain identical electrical performance within the specified operating temperature range of -55°C to 105°C.

Q: Are both connectors suitable for solder termination on printed circuit boards?

A: Yes. Both the 5205859-1 and 205859-1 feature solder termination and through-hole right-angle mounting. Both are designed for direct soldering to PCB pads without additional mounting hardware.

Q: What is the current-carrying capacity of these connectors?

A: Both connectors are rated for 6A continuous current at 125V. This rating applies uniformly across all 37 positions in the connector.

Q: Do these connectors require any special handling or storage conditions?

A: Both connectors carry Moisture Sensitivity Level (MSL) 1, classified as Unlimited. This indicates no special moisture control or baking procedures are required prior to soldering.

Q: What is the shell size designation "4 (DC, C)" and why is it important for substitution?

A: Shell size 4 (DC, C) is a standardized D-Sub connector classification that defines the physical dimensions and pin layout. This designation must match exactly between the original part and any substitute to ensure mechanical compatibility with mating connectors and PCB footprints.

Q: Are there any inventory considerations when selecting between these parts?

A: The 5205859-1 has 896 pieces in stock, while the 205859-1 has 1234 pieces in stock. Availability may influence selection timing, but both parts are currently available.
