Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2178234-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: TE Connectivity AMP Connectors
• Series: Mark III
• Gender: Female, Receptacle
• Terminal Size: 0.250" (6.35mm)
• Terminal Type: Quick Connect, Disconnect
• Mounting Type: Free Hanging (In-Line)
• Color: Green
• Material: Polyamide (PA6), Nylon 6
• Stacking Direction: Top to Bottom

The substitute part 5-2178234-1 maintains full compatibility across all mandatory parameters. Both components are housed in identical Mark III series receptacle housings with matching electrical and mechanical specifications. The primary distinction is the product status transition from Obsolete to Active, indicating continued manufacturing availability and compliance with current regulatory standards.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-2178234-1 is the direct equivalent for the obsolete 2178234-1. Both components share identical electrical and mechanical specifications within the Mark III series housing connector family. The 5-2178234-1 maintains full RoHS compliance and carries an Active product status, ensuring ongoing availability and manufacturer support.

Selection of the 5-2178234-1 is appropriate for new designs and replacement applications where the 2178234-1 is no longer available. The transition from ROHS3 Compliant to RoHS Compliant status reflects current regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 5-2178234-1 be used as a direct replacement for the 2178234-1?

A: Yes. The 5-2178234-1 is a direct equivalent substitute. Both components share identical terminal size (0.250"), position count (2), gender (Female Receptacle), mounting type (Free Hanging In-Line), color (Green), and material composition (Polyamide PA6 Nylon 6). The primary difference is product status: the 2178234-1 is Obsolete while the 5-2178234-1 is Active.

Q: What are the key compatibility parameters for this connector housing?

A: Compatibility is determined by: Mark III series designation, 0.250" (6.35mm) terminal size, 2-position configuration, Female Receptacle gender, Quick Connect/Disconnect terminal type, Free Hanging In-Line mounting, Green color, and Polyamide PA6 Nylon 6 material. All substitute parts must match these parameters exactly.

Q: Are there any compliance differences between the main part and substitute?

A: Both parts are RoHS compliant. The 2178234-1 carries ROHS3 Compliant status while the 5-2178234-1 carries RoHS Compliant status. Both maintain MSL rating 1 (Unlimited) and are suitable for applications requiring regulatory compliance.

Q: Does the part number prefix change affect functionality?

A: No. The prefix change from 2178234-1 to 5-2178234-1 reflects manufacturer part numbering conventions and product status updates. The functional specifications, electrical characteristics, and mechanical dimensions remain identical.

Q: Are contacts included with these housing components?

A: No. Both the 2178234-1 and 5-2178234-1 are housing components only. Contacts are not included and must be sourced separately for use with 0.250" (6.35mm) Quick Connect applications.
