TE Connectivity Deutsch Connectors 6-968975-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Deutsch Connectors 6-968975-1 is a 21-position rectangular connector receptacle housing designed for applications requiring crimp-terminated female socket contacts with a 5.00mm pitch. This component operates within the MCP series and is classified as Active product status. The housing features a blue polybutylene terephthalate (PBT) glass-filled insulation material with latch lock fastening and free-hanging in-line mounting capability. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative housing colors or operating temperature ranges are acceptable for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6-968975-1 are identified based on strict equivalence of the following critical parameters:

• Number of Positions: 21 positions (fixed requirement)
• Pitch: 0.197" (5.00mm) (fixed requirement)
• Number of Rows: 3 rows (fixed requirement)
• Row Spacing: 0.217" (5.51mm) (fixed requirement)
• Connector Type: Receptacle (fixed requirement)
• Contact Type: Female Socket (fixed requirement)
• Mounting Type: Free Hanging (In-Line) (fixed requirement)
• Contact Termination: Crimp (fixed requirement)
• Fastening Type: Latch Lock (fixed requirement)
• Insulation Material: Polybutylene Terephthalate (PBT), Glass Filled (fixed requirement)
• Series: MCP (fixed requirement)

Substitute parts 7-968975-1 and 8-968975-1 maintain all critical electrical and mechanical parameters. Variations in housing color (Natural or Brown versus Blue) and operating temperature range do not affect the core connector functionality or mating interface. All substitute parts retain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All three connector housings (6-968975-1, 7-968975-1, and 8-968975-1) are Active products manufactured by TE Connectivity Deutsch Connectors within the MCP series. Each part maintains ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity classification, confirming suitability for standard industrial and commercial applications.

Selection between these parts is determined by application-specific requirements:

6-968975-1 (Blue Housing) is selected for applications requiring the standard blue color designation and operating temperature range of -30°C to 100°C.

7-968975-1 (Natural Housing) provides identical electrical and mechanical performance with a natural color housing and the same -30°C to 100°C operating temperature range.

8-968975-1 (Brown Housing) offers an extended operating temperature range of -40°C to 120°C, accommodating applications requiring lower minimum or higher maximum temperature performance. The brown color housing distinguishes this variant.

All three parts share identical contact configuration, pitch, row spacing, mounting type, termination method, and fastening mechanism, ensuring direct interchangeability at the mating interface level. The choice between parts depends on color coding requirements, thermal operating envelope specifications, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Are the 6-968975-1, 7-968975-1, and 8-968975-1 connectors mechanically interchangeable?

A: Yes. All three parts maintain identical pitch (0.197" / 5.00mm), number of positions (21), row configuration (3 rows with 0.217" / 5.51mm spacing), mounting type (free hanging in-line), and fastening mechanism (latch lock). The mating interface is identical across all three variants.

Q: What is the primary difference between these substitute parts?

A: The primary differences are housing color and operating temperature range. The 6-968975-1 features a blue housing, the 7-968975-1 features a natural housing, and the 8-968975-1 features a brown housing with an extended operating temperature range of -40°C to 120°C compared to -30°C to 100°C for the other two variants.

Q: Can I use the 8-968975-1 in place of the 6-968975-1 in all applications?

A: The 8-968975-1 is electrically and mechanically compatible with the 6-968975-1. However, the extended operating temperature range (-40°C to 120°C) of the 8-968975-1 is a design feature that may not be necessary for all applications. Selection should be based on the specific thermal requirements of your application.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts (6-968975-1, 7-968975-1, and 8-968975-1) are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity classification.

Q: Do these connector housings include contacts?

A: No. All three parts are connector housings only. Contacts are not included and must be ordered separately as specified in the product documentation.

Q: What is the significance of the base product number 968975?

A: The base product number 968975 identifies the core connector design shared across all three variants. The prefix digits (6, 7, or 8) distinguish the specific color and thermal rating variant within this product family.

Q: Can I mix and match these connectors in the same assembly?

A: Yes, from an electrical and mechanical standpoint, these connectors are fully interchangeable. However, mixing different housing colors may affect visual identification and assembly traceability. Design and assembly documentation should specify color requirements if color coding is critical to your application.
