TE Connectivity AMP Connectors 176274-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 176274-9 is a 6-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 classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the original part number is unavailable, discontinued, or when alternative housing colors or series configurations meet the same functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 176274-9 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Equivalence Criteria:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 6
• Pitch: 0.156" (3.96mm)
• Number of Rows: 2
• Row Spacing: 0.181" (4.60mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Variation Parameters:

• Housing Color (Black, Blue, Natural)
• Series designation (Universal Power, Power Double Lock)
• Operating Temperature Range (within specified limits)
• Insulation Material composition
• RoHS compliance status

The substitute parts 176274-6, 3-177901-6, and 368576-1 maintain all primary equivalence criteria while differing in housing color, series classification, and operating temperature specifications. These variations do not affect the core mechanical and electrical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

176274-9 (Black Housing, Universal Power Series) Select this part when black housing color is specified in the application design. Operating temperature range extends to 105°C. ROHS3 compliance status applies. This part maintains the Universal Power series designation.

176274-6 (Blue Housing, Universal Power Series) This substitute provides identical electrical and mechanical interface characteristics to the 176274-9 with blue housing color substitution. Operating temperature range extends to 105°C. ROHS3 compliance status applies. Maintains the Universal Power series designation. Select when blue housing is acceptable or required.

3-177901-6 (Blue Housing, Power Double Lock Series) This substitute provides identical electrical and mechanical interface characteristics with blue housing color and Power Double Lock series designation. Operating temperature range and insulation material specifications are not provided in available documentation. RoHS compliance status is confirmed. Select when Power Double Lock series configuration is required and operating temperature specifications are confirmed through additional documentation.

368576-1 (Natural Housing, Power Double Lock Series) This substitute provides identical electrical and mechanical interface characteristics with natural housing color and Power Double Lock series designation. Operating temperature range is limited to -30°C ~ 65°C, which is more restrictive than the main part. RoHS compliance status is confirmed. Select only when operating temperature does not exceed 65°C and Power Double Lock series configuration is required.

Frequently Asked Questions (FAQ)

Q: Can 176274-6 be used as a direct replacement for 176274-9? A: Yes. The 176274-6 maintains all critical electrical and mechanical parameters including connector type, contact type, position count, pitch, row spacing, mounting type, termination method, and fastening type. The only difference is housing color (blue versus black). Both parts support the same operating temperature range (-30°C ~ 105°C) and carry ROHS3 compliance.

Q: What is the primary difference between the Universal Power series (176274-9, 176274-6) and the Power Double Lock series (3-177901-6, 368576-1)? A: The series designation indicates different connector families within the TE Connectivity AMP Connectors product line. Both series maintain identical pitch, position count, row spacing, and fastening characteristics. The series difference reflects internal design variations and connector family classification rather than interface incompatibility.

Q: Can 368576-1 be used in applications requiring operation above 65°C? A: No. The 368576-1 operating temperature range is specified as -30°C ~ 65°C, which is more restrictive than the main part 176274-9 (-30°C ~ 105°C). Applications requiring operation above 65°C must use 176274-9, 176274-6, or 3-177901-6.

Q: Are contacts included with these connector housings? A: No. All parts in this equivalency group are connector housings only. Contacts are not included and must be sourced separately.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating of 1? A: MSL 1 (Unlimited) indicates that these connector housings have unlimited shelf life and do not require special moisture control during storage or handling. This applies to all parts in this equivalency group.

Q: Can housing color be changed between substitute parts without affecting connector function? A: Yes. Housing color (black, blue, or natural) is a cosmetic and identification parameter only. It does not affect electrical performance, mechanical interface compatibility, or functional characteristics. Color selection is based on application design requirements or visual identification needs.

Q: What packaging format is available for these parts? A: All parts in this equivalency group are supplied in Bulk packaging format.

Q: Are all substitute parts RoHS compliant? A: Yes. All parts carry RoHS compliance status. The main part (176274-9) and 176274-6 are ROHS3 compliant. The substitute parts 3-177901-6 and 368576-1 are RoHS compliant.
