Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 213045-1 and equivalent part 1-1757823-2 is based on matching the following critical parameters:

Matched Parameters:

• Connector style: D-Sub, High Density
• Connector type: Plug, Male Pins
• Number of positions: 104
• Number of rows: 5
• Shell size and connector layout: 6
• Contact type: Signal
• Flange feature: Housing/Shell (Unthreaded)
• Contact finish: Gold
• Series compatibility: AMPLIMITE 90

Differing Parameters:

• Termination method: Solder (213045-1) versus Crimp (1-1757823-2)
• Mounting type: Through Hole (213045-1) versus Free Hanging In-Line (1-1757823-2)
• Shell material finish: Cadmium Plated (213045-1) versus Yellow Chromate Plated Zinc (1-1757823-2)
• Contact material: Copper Nickel Alloy (213045-1) versus Copper Alloy (1-1757823-2)
• Current rating: Not specified (213045-1) versus 7.5A (1-1757823-2)
• Operating temperature: Not specified (213045-1) versus -55°C ~ 125°C (1-1757823-2)
• RoHS status: Non-compliant (213045-1) versus ROHS3 Compliant (1-1757823-2)

Parameter Comparison

Engineering Selection Recommendations

Part 213045-1 Selection Criteria:

• Applications requiring through-hole solder termination to printed circuit boards
• Designs where cadmium-plated steel shell finish is specified
• Applications where RoHS non-compliance is acceptable or not required
• Standard commercial and industrial connector applications

Part 1-1757823-2 Selection Criteria:

• Applications requiring crimp termination to wire harnesses or free-hanging configurations
• Designs requiring ROHS3 compliance certification
• Aerospace, defense, and marine applications with MIL-DTL-24308 specification requirements
• Applications requiring documented operating temperature range (-55°C ~ 125°C) and current rating (7.5A)
• Designs where yellow chromate plated zinc shell finish is specified

Both parts maintain electrical and mechanical compatibility through identical 104-position high-density D-Sub configuration, shell size 6 layout, and gold-plated signal contacts. Selection between these parts depends on termination method requirements, mounting configuration, compliance certifications, and environmental specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can 213045-1 and 1-1757823-2 be used interchangeably in the same connector housing?

A: Both connectors share identical 104-position high-density D-Sub configuration and shell size 6 layout, making them mechanically compatible with the same mating receptacle. However, they differ in termination method (solder versus crimp) and mounting type (through-hole versus free-hanging), which determines their application context rather than direct interchangeability.

Q: What is the primary difference between these two connector variants?

A: The main difference is termination method. Part 213045-1 uses solder termination for through-hole PCB mounting, while part 1-1757823-2 uses crimp termination for wire harness or free-hanging applications. Additionally, 1-1757823-2 includes military specification compliance (MIL-DTL-24308) and ROHS3 certification.

Q: Does the shell material finish difference affect electrical performance?

A: Both cadmium plating (213045-1) and yellow chromate plated zinc (1-1757823-2) provide corrosion protection for the steel shell. The choice between finishes is determined by application environment and compliance requirements rather than electrical performance, as both maintain equivalent signal integrity through gold-plated contacts.

Q: Which part should be selected for new designs?

A: Part 1-1757823-2 is recommended for new designs requiring ROHS3 compliance, documented operating temperature specifications, and military or aerospace applications. Part 213045-1 remains suitable for existing designs and applications where RoHS compliance is not mandated.

Q: Are the contact materials functionally equivalent?

A: Both copper nickel alloy (213045-1) and copper alloy (1-1757823-2) contacts provide reliable signal transmission with gold plating. Contact material selection reflects manufacturing process differences between solder and crimp termination methods rather than functional performance differences.

Q: What inventory considerations apply to these parts?

A: Part 213045-1 has 1,040 units in stock, while 1-1757823-2 has 903 units available. Both are active production parts from TE Connectivity with established supply chains.
