TE Connectivity 177909-4 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 177909-4 is a 6-position rectangular connector receptacle housing designed for the Power Double Lock series. This component functions as the housing structure for tab-contact receptacle connectors with a 0.156" (3.96mm) pitch configuration. The part is panel-mount, snap-in style with crimp termination and latch holder fastening. As an active product with 787 units in current inventory, equivalent substitute parts may be required due to color specification requirements, regional availability, or inventory optimization in production environments.

Key Parameters

Substitute Part Grouping Explanation

The 177909-4 connector housing belongs to the TE Connectivity Power Double Lock series and shares identical electrical and mechanical specifications with its substitute part 177909-1. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Connector type (Receptacle)
• Number of positions (6)
• Pitch specification (0.156" / 3.96mm)
• Row configuration (2 rows with 0.181" / 4.60mm spacing)
• Mounting method (Panel Mount, Snap-In)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Holder)
• Insulation material (Polyamide PA66, Nylon 6/6)
• Operating temperature range (-30°C ~ 105°C)
• Base product number (177909)

The primary difference between the main part and its substitute is the housing color: 177909-4 features yellow insulation, while 177909-1 features natural (undyed) insulation. Both parts maintain identical mechanical fit, electrical performance, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 177909-4 and 177909-1 are active products with full regulatory compliance. The 177909-4 (yellow) maintains RoHS compliance status, while the 177909-1 (natural) carries ROHS3 compliance certification. Selection between these parts should be based on application requirements:

The 177909-4 yellow housing variant is suitable for applications requiring color-coded connector identification or visual circuit tracing. The 177909-1 natural housing variant provides equivalent electrical and mechanical performance with enhanced regulatory documentation through ROHS3 certification and offers greater inventory availability (2510 units versus 787 units).

Both parts are MSL Level 1 (Unlimited moisture sensitivity), indicating no special storage or handling requirements. Both maintain identical operating temperature ranges and are suitable for industrial and commercial applications within the -30°C to 105°C specification window.

Frequently Asked Questions (FAQ)

Q: Can 177909-1 be used as a direct replacement for 177909-4 in existing designs?

A: Yes. The 177909-1 is electrically and mechanically identical to the 177909-4. The only difference is housing color (natural versus yellow). Both parts share identical pitch, row spacing, mounting configuration, termination method, and operating specifications. Substitution is valid from an engineering standpoint.

Q: Does the color difference affect connector performance or compatibility?

A: No. Housing color is a cosmetic and identification feature only. It does not affect electrical performance, mechanical fit, or contact integrity. Both yellow and natural housings are manufactured from identical Polyamide PA66 material with the same mechanical properties.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. Both parts meet hazardous substance restrictions and are suitable for regulated applications.

Q: Are contacts included with these connector housings?

A: No. Both the 177909-4 and 177909-1 are housings only. Contacts are not included and must be sourced separately. The housing accommodates 6 tab-type contacts with crimp termination.

Q: What is the significance of MSL Level 1 rating?

A: MSL Level 1 (Unlimited) indicates these connector housings have no moisture sensitivity limitations. They do not require special dry-pack storage, desiccant handling, or bake-out procedures prior to assembly. Standard storage conditions are acceptable.

Q: Can these housings be used in applications outside the -30°C to 105°C range?

A: No. Both parts are rated for operation within the -30°C to 105°C temperature range. Applications requiring extended temperature performance require alternative connector housing designs.

Q: What mounting methods are supported by these housings?

A: Both housings support panel-mount, snap-in installation. The snap-in fastening mechanism with latch holder provides secure mounting to standard panel thicknesses without additional hardware.
