TE Connectivity AMP Connectors 175778-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 175778-9 is a 9-position rectangular connector receptacle housing with 2.00mm pitch, designed for free-hanging in-line applications. This connector operates within the temperature range of -30°C to 105°C and utilizes crimp termination for contact attachment. The part is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design revisions, or application-specific performance requirements within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 175778-9 are identified based on strict equivalence of the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (9), pitch (2.00mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), color (natural), and moisture sensitivity level (MSL 1). All substitute parts maintain these core electrical and mechanical specifications. Variations in operating temperature range, insulation material composition, series designation, and RoHS certification status are documented in the parameter comparison table. Substitution is valid when the application requirements fall within the overlapping operational parameters of both the primary part and the selected substitute.

Parameter Comparison

Engineering Selection Recommendations

All three parts—175778-9, 179228-9, and 440129-9—are Active product status and maintain full compliance with RoHS regulations. Selection between these parts is determined by application-specific operating temperature requirements and material composition preferences.

The primary part 175778-9 operates across -30°C to 105°C with PA66/Nylon 6/6 insulation material and carries ROHS3 certification.

Substitute 179228-9 operates across -55°C to 85°C with identical PA66/Nylon 6/6 insulation material and RoHS compliance. This part is suitable for applications requiring extended low-temperature performance below -30°C, provided the upper temperature limit of 85°C remains acceptable.

Substitute 440129-9 operates across -25°C to 105°C with thermoplastic insulation material and RoHS compliance. This part is suitable for applications requiring the full upper temperature range of 105°C with thermoplastic material properties, and operates within the primary part's lower temperature boundary of -25°C.

All three parts share identical electrical and mechanical specifications for connector type, contact configuration, pitch, mounting method, and termination type, ensuring mechanical and electrical interchangeability within their respective temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: What are the core electrical and mechanical parameters that define substitution compatibility for the 175778-9?

A: The 175778-9 substitutes are defined by equivalence in the following parameters: 9-position receptacle connector, female socket contacts, 2.00mm pitch, single-row configuration, free-hanging in-line mounting, crimp termination, natural color, and MSL 1 moisture sensitivity rating. All substitute parts maintain these specifications.

Q: How do operating temperature ranges differ between the primary part and substitutes?

A: The primary part 175778-9 operates from -30°C to 105°C. Substitute 179228-9 operates from -55°C to 85°C, providing extended low-temperature capability but with a reduced upper temperature limit. Substitute 440129-9 operates from -25°C to 105°C, maintaining the full upper temperature range with a slightly higher lower temperature threshold.

Q: What is the difference in insulation material between the parts?

A: The primary part 175778-9 and substitute 179228-9 both use Polyamide (PA66), Nylon 6/6 insulation material. Substitute 440129-9 uses thermoplastic insulation material. Material selection should align with application environmental and mechanical requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The primary part 175778-9 is ROHS3 compliant. Substitutes 179228-9 and 440129-9 are RoHS compliant. All parts meet regulatory requirements for hazardous substance restrictions.

Q: Can the 175778-9 be directly replaced with either substitute in any application?

A: Direct replacement is valid only when the application operating temperature range falls within the overlapping specifications of both parts. For applications operating between -25°C and 85°C, all three parts are interchangeable. For applications below -25°C or above 85°C, specific part selection is required based on temperature requirements.

Q: What is the significance of the series designation difference between CT and High Performance Interconnect (HPI)?

A: Series designation indicates product family classification. The primary part 175778-9 belongs to the CT series, while substitute 440129-9 belongs to the High Performance Interconnect (HPI) series. Both series maintain equivalent electrical and mechanical specifications for this 9-position 2.00mm pitch receptacle housing configuration.

Q: Are contacts included with these connector housings?

A: No. All three parts—175778-9, 179228-9, and 440129-9—are connector housings only. Contacts are not included and must be sourced separately as required for the application.

Q: What packaging format is available for these parts?

A: All three parts are supplied in Bulk packaging format.
