TE Connectivity 770847-1 Rectangular Connector Plug Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 770847-1 is a 3-position rectangular connector plug housing from the Mini-Universal MATE-N-LOK series. This component serves as the housing interface for crimp-terminated male or female contacts in free-hanging inline applications. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, allowing for interchangeable housing selection based on availability, color specification, or inventory requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector plug housings is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Connector type (Plug)
• Number of positions (3)
• Pitch specification (0.163" / 4.14mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Lock)
• Series compatibility (Mini-Universal MATE-N-LOK)

Allowable Variation Parameters:

• Housing color (White vs. Natural)
• Insulation material composition within polyamide family (PA vs. PA66)
• Operating temperature minimum threshold (provided maximum threshold is maintained or exceeded)
• RoHS compliance status (both compliant)

The substitute part 172166-1 maintains all mandatory equivalence parameters, confirming direct interchangeability at the housing interface level. Variations in color and material composition do not affect electrical or mechanical connector function.

Parameter Comparison

Engineering Selection Recommendations

Both 770847-1 and 172166-1 are Active product status components manufactured by TE Connectivity within the Mini-Universal MATE-N-LOK series. Both parts maintain RoHS compliance and unlimited moisture sensitivity rating (MSL 1), suitable for standard industrial and commercial applications.

Selection based on compliance and availability:

The 770847-1 (White housing) provides the widest operating temperature range (-55°C to 105°C), making it suitable for extended temperature environments. This part carries RoHS3 compliance designation.

The 172166-1 (Natural housing) operates within -20°C to 105°C and carries RoHS compliance designation. This part offers higher inventory availability (7727 pieces versus 1025 pieces for 770847-1).

Both parts accept identical crimp-terminated contacts and utilize latch lock fastening mechanisms. Housing color and insulation material composition (PA versus PA66 polyamide) represent the primary differentiators and do not affect electrical interface compatibility or mechanical mating characteristics.

Frequently Asked Questions (FAQ)

Q: Can 172166-1 be used as a direct replacement for 770847-1 in existing assemblies?

A: Yes. Both parts are 3-position plug housings with 0.163" (4.14mm) pitch, identical mounting type, and compatible fastening mechanisms. The housings accept the same crimp-terminated contacts and maintain equivalent electrical and mechanical interface specifications.

Q: What is the difference between the White (770847-1) and Natural (172166-1) housing colors?

A: Color is a cosmetic variation that does not affect electrical performance or mechanical compatibility. Selection between White and Natural housing is based on application requirements, assembly aesthetics, or inventory availability.

Q: Are the insulation materials PA and PA66 interchangeable in this application?

A: Both polyamide (PA) and polyamide 6/6 (PA66) are nylon-based insulation materials used in this connector series. The material variation does not affect the housing's ability to accept standard Mini-Universal MATE-N-LOK contacts or maintain latch lock fastening integrity.

Q: Does the operating temperature range difference (-55°C to 105°C versus -20°C to 105°C) affect substitution eligibility?

A: The 172166-1 operates within a narrower minimum temperature range. If the application requires operation below -20°C, the 770847-1 is required. For applications operating at -20°C or above, both parts are functionally equivalent.

Q: Are contacts included with these housing parts?

A: No. Both 770847-1 and 172166-1 are housings only. Crimp-terminated male or female contacts must be sourced separately and inserted into the housing cavities.

Q: What is the significance of the RoHS3 versus RoHS compliance designation?

A: Both parts meet RoHS compliance requirements. RoHS3 represents the current regulatory standard. Both parts are suitable for applications requiring RoHS-compliant components.

Q: Can these housings be used in applications requiring unlimited moisture exposure?

A: Yes. Both parts carry Moisture Sensitivity Level (MSL) 1 rating, indicating unlimited moisture tolerance. No special drying or storage procedures are required prior to assembly or deployment.
