TE Connectivity 106527-4 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 106527-4 is a 4-position rectangular connector receptacle housing with 0.165" (4.20mm) pitch, designed for free-hanging in-line mounting applications. This part operates as a female socket receptacle with crimp termination and latch lock fastening. The 106527-4 is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design and procurement requirements. Substitute parts maintain the same electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict parametric matching across electrical and mechanical dimensions. The following parameters establish substitution validity:

Critical Matching Parameters:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (4)
Pitch (0.165" / 4.20mm)
Number of rows (2)
Row spacing (0.165" / 4.20mm)
Mounting type (Free Hanging In-Line)
Contact termination (Crimp)
Fastening type (Latch Lock)
Moisture sensitivity level (MSL 1)

All identified substitute parts match these critical parameters. Variations in color (Natural vs. Black), insulation material composition, series designation, and manufacturer do not affect functional interchangeability within the specified electrical and mechanical constraints. Parts are grouped by manufacturer and product status to facilitate procurement decisions.

Engineering Selection Recommendations

TE Connectivity AMP Connectors Substitutes (Same Manufacturer):

The TE Connectivity 794954-4 (VAL-U-LOK series, Natural) provides direct substitution with active product status and RoHS compliance. This part maintains identical electrical and mechanical specifications to the 106527-4 while offering superior availability (2400 units in stock). Operating temperature range is specified as -40°C to 105°C.

The TE Connectivity 1586075-4 (VAL-U-LOK series, Black) is a parametric equivalent with identical specifications except for color designation. This part carries ROHS3 compliance and active status. Selection is appropriate where black housing color is required or specified.

Molex Mini-Fit Jr 5557 Series Substitutes:

The Molex 0039012040 (Natural) and 0039013042 (Natural) are parametric equivalents from the Mini-Fit Jr 5557 series. Both parts are active, ROHS3 compliant, and REACH unaffected. Insulation material is specified as Polyamide (PA66), Nylon 6/6. The 0039012040 offers the highest inventory availability (252982 units).

The Molex 0039013045 (Black) is a parametric equivalent with black housing color, ROHS3 compliance, and REACH unaffected status. Insulation material includes glass-filled Polyamide (PA66), Nylon 6/6.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification and are suitable for direct functional replacement in applications requiring 4-position, 0.165" pitch rectangular connector housings with crimp termination and latch lock fastening.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the 106527-4?

A: Substitution is determined by matching critical parameters: 4-position receptacle configuration, 0.165" (4.20mm) pitch, 2-row layout with 0.165" row spacing, free-hanging in-line mounting, crimp termination, latch lock fastening, and MSL 1 classification. All listed substitute parts meet these requirements.

Q: Does color affect interchangeability?

A: Color variations (Natural vs. Black) do not affect electrical or mechanical interchangeability. Selection between Natural and Black housing is based on application requirements or design specifications, not functional compatibility.

Q: Are there differences between TE Connectivity and Molex substitutes?

A: Both manufacturers provide parametric equivalents meeting identical electrical and mechanical specifications. Differences exist in series designation (AMP-DUAC vs. VAL-U-LOK vs. Mini-Fit Jr 5557), insulation material composition, and compliance certifications. All are functionally interchangeable within the specified parameters.

Q: What is the significance of product status (Active vs. Obsolete)?

A: The 106527-4 is classified as obsolete, indicating discontinued production. Active substitute parts (794954-4, 1586075-4, 0039012040, 0039013042, 0039013045) are currently manufactured and available for procurement. Active status ensures long-term supply chain reliability.

Q: How do RoHS and REACH compliance affect substitution?

A: The 106527-4 has undefined REACH status. Substitute parts with ROHS3 compliance and REACH unaffected status (Molex parts) or vendor-undefined REACH status (TE Connectivity VAL-U-LOK parts) provide regulatory flexibility. Compliance requirements should be verified against specific application and regional regulations.

Q: What is the difference between the Molex Natural options (0039012040 vs. 0039013042)?

A: Both parts are parametric equivalents from the Mini-Fit Jr 5557 series with identical electrical and mechanical specifications. The 0039012040 offers significantly higher inventory availability (252982 units vs. 30904 units). Selection between these parts is based on procurement lead time and inventory requirements.

Q: Are contacts included with these connector housings?

A: No. All listed parts (main and substitutes) are connector housings only. Contacts are not included and must be procured separately according to application requirements.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This classification applies to all listed parts and simplifies inventory management.
