TE Connectivity AMP Connectors 176273-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 176273-9 is a 4-position rectangular connector housing plug with 0.156" (3.96mm) pitch spacing. This connector is designed for free-hanging, in-line applications requiring crimp termination with latch lock fastening. The part is manufactured from Polyamide (PA66) Nylon 6/6 material and operates across a temperature range of -30°C to 105°C. The 176273-9 is an active product with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are necessary when specific color requirements, series compatibility, or inventory availability necessitate alternative housing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings 176273-9 is determined by strict equivalence across the following critical parameters: connector type (plug), contact type (female socket), number of positions (4), pitch spacing (0.156"/3.96mm), number of rows (2), row spacing (0.181"/4.60mm), mounting type (free hanging in-line), contact termination method (crimp), fastening mechanism (latch lock), insulation material (Polyamide PA66 Nylon 6/6), and operating temperature range (-30°C to 105°C). All substitute parts listed maintain these specifications without deviation. Variations in color, series designation, and RoHS compliance status do not affect mechanical or electrical interchangeability. The substitute parts 176273-1, 177900-4, and 177900-6 are functionally equivalent housings that accept identical contact configurations and mate with compatible receptacle connectors.

Parameter Comparison

Engineering Selection Recommendations

All four connector housings listed are active products with confirmed RoHS compliance status. The 176273-9 and 177900-6 both carry ROHS3 certification, while 176273-1 and 177900-4 carry standard RoHS compliance. Selection between these parts should be based on application-specific requirements including color coding standards, series compatibility with existing connector systems, and inventory availability. The 176273-1 substitute maintains identical Universal Power series designation as the main part 176273-9, differing only in housing color (Natural versus Black). The 177900-4 and 177900-6 substitutes belong to the Power Double Lock series and are available in Yellow and Blue housings respectively. All parts maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability in applications where housing color does not impose design constraints.

Frequently Asked Questions (FAQ)

Q: Can 176273-1 be used as a direct replacement for 176273-9?

A: Yes. The 176273-1 is a parametric equivalent with identical electrical and mechanical specifications. The only difference is housing color (Natural versus Black). Both parts share the same Universal Power series designation, 4-position configuration, 0.156" pitch, and crimp termination requirements.

Q: What is the difference between the Universal Power series (176273-9, 176273-1) and the Power Double Lock series (177900-4, 177900-6)?

A: Both series maintain identical contact pitch, row spacing, position count, and termination specifications. The series designation reflects product line categorization but does not affect mechanical or electrical interchangeability. Selection between series should follow application and system compatibility requirements.

Q: Are the 177900-4 and 177900-6 substitutes compatible with contacts designed for 176273-9?

A: Yes. All four connector housings accept identical crimp-terminated female socket contacts. The 4-position, 0.156" pitch configuration is consistent across all parts, ensuring contact compatibility regardless of housing color or series designation.

Q: Does housing color affect electrical performance?

A: No. Housing color is a visual identification feature only and does not impact electrical characteristics, impedance, signal integrity, or operating performance. Color selection is determined by application requirements, industry standards, or system color-coding conventions.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating of 1?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. All four connector housings carry this rating, confirming they do not require special dry-pack storage or handling procedures prior to assembly.

Q: Can these connectors be used in applications requiring ROHS3 compliance?

A: The 176273-9 and 177900-6 are explicitly ROHS3 compliant. The 176273-1 and 177900-4 carry standard RoHS compliance. Applications with specific ROHS3 requirements should specify either 176273-9 or 177900-6.

Q: Are contacts included with these connector housings?

A: No. All four parts are housings only. Contacts must be sourced separately and crimped into the housing according to TE Connectivity specifications for the applicable contact series.
