TE Connectivity 1-106527-2 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-106527-2 is a 12-position rectangular connector receptacle housing with 0.165" (4.20mm) pitch, designed for free-hanging in-line mounting applications. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts to maintain design continuity and ensure supply chain availability. The housing accommodates crimp-terminated female socket contacts with latch lock fastening and operates across the -40°C to 105°C temperature range.

Substitute Part Grouping Explanation

Substitution eligibility for the 1-106527-2 is determined by strict equivalence across the following critical parameters: 12-position count, 0.165" (4.20mm) pitch, 2-row configuration with 0.165" (4.20mm) row spacing, receptacle connector type with female socket contacts, free-hanging in-line mounting, crimp termination, and latch lock fastening. All substitute parts must maintain these electrical and mechanical specifications to ensure form, fit, and function compatibility.

Substitute parts are grouped into two categories:

TE Connectivity VAL-U-LOK Series (Active Status): Parts 1-794954-2, 1-1586019-2, 1-1586765-2, and 1-1969603-2 are active production alternatives within the TE Connectivity portfolio. These parts share identical electrical and mechanical parameters with the obsolete 1-106527-2, differing only in color designation and compliance certifications.

Cross-Manufacturer Alternative: Part 0039012120 (Molex Mini-Fit Jr 5557 Series) provides parametric equivalence across all critical dimensions and electrical specifications, offering a cross-manufacturer substitute option.

Obsolete Alternative: Part 1-2029097-2 maintains full parameter equivalence but carries obsolete product status, limiting its utility for new designs.

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity VAL-U-LOK Series): Parts 1-1969603-2 and 1-1586019-2 are recommended as primary substitutes. Both are active production components with ROHS3 compliance certification, ensuring regulatory alignment with current environmental standards. Part 1-1969603-2 offers the highest inventory availability (4,398 units) and maintains natural color specification matching the original 1-106527-2. Part 1-1586019-2 provides equivalent specifications with substantial inventory (3,012 units).

Color-Variant Alternative: Part 1-1586765-2 is functionally equivalent with ROHS3 and REACH Unaffected certifications but features white insulation material instead of natural. This part is suitable for applications where color differentiation is required or preferred.

Secondary TE Connectivity Option: Part 1-794954-2 is an active alternative with RoHS Compliant status and bulk packaging, suitable for high-volume applications with established supply chain relationships.

Cross-Manufacturer Option: Part 0039012120 (Molex Mini-Fit Jr 5557 Series) provides parametric equivalence with ROHS3 compliance and REACH Unaffected status. This part offers the highest inventory level (7,669 units) and represents a viable alternative for applications permitting cross-manufacturer substitution. The insulation material specification differs (PA66 Nylon 6/6 versus PA Nylon), but electrical and mechanical parameters remain equivalent.

Obsolete Parts: Part 1-2029097-2 carries obsolete product status and should not be selected for new designs despite parameter equivalence.

Frequently Asked Questions (FAQ)

Q: Can 1-1586765-2 (white) be substituted for 1-106527-2 (natural) in existing designs?

A: Yes. The 1-1586765-2 maintains identical electrical and mechanical specifications across all critical parameters: 12 positions, 0.165" (4.20mm) pitch, 2-row configuration, receptacle type, female socket contacts, free-hanging mounting, crimp termination, and latch lock fastening. The color difference is cosmetic and does not affect functional compatibility. However, color-coded connector systems may require design review to confirm color substitution is acceptable.

Q: What is the difference between TE Connectivity VAL-U-LOK substitutes and the Molex 0039012120?

A: All parts maintain identical electrical and mechanical specifications. The primary differences are manufacturer (TE Connectivity versus Molex), series designation (VAL-U-LOK versus Mini-Fit Jr 5557), and insulation material specification (PA Nylon versus PA66 Nylon 6/6). Both materials are polyamide-based with equivalent performance characteristics. Cross-manufacturer substitution requires confirmation that connector mating interfaces are compatible with existing plug assemblies.

Q: Why is 1-106527-2 listed as obsolete when active substitutes exist?

A: The 1-106527-2 is an older AMP-DUAC series component that has been superseded by the VAL-U-LOK series within TE Connectivity's product portfolio. The VAL-U-LOK alternatives offer improved compliance certifications (ROHS3 versus unspecified), active production status, and higher inventory availability. Obsolescence does not indicate functional deficiency but rather reflects manufacturer product lifecycle management and transition to newer series offerings.

Q: Are contacts included with these connector housings?

A: No. All listed parts, including the main part 1-106527-2 and all substitutes, are housings only. Contacts must be sourced separately and selected to match the 0.165" (4.20mm) pitch specification and crimp termination requirement.

Q: What packaging options are available for these substitutes?

A: TE Connectivity VAL-U-LOK substitutes (1-794954-2, 1-1586019-2, 1-1586765-2, 1-1969603-2) are supplied in bulk packaging. The Molex 0039012120 is also supplied in bulk packaging. The original 1-106527-2 packaging specification is not defined in available documentation.

Q: Can these parts be used interchangeably in PCB-mounted applications?

A: All listed parts are specified for free-hanging in-line mounting, indicating they are designed for cable or harness assembly applications rather than direct PCB mounting. PCB-mounted applications require connector housings with through-hole or surface-mount termination options, which are not represented in this substitute list.

Q: What compliance certifications should be prioritized for new designs?

A: ROHS3 compliance is the current regulatory standard for new designs. Parts 1-1586765-2, 1-1969603-2, and 0039012120 carry ROHS3 certification. For applications requiring REACH compliance confirmation, part 1-1586765-2 and 0039012120 are designated as REACH Unaffected. Parts with Vendor Undefined REACH status require direct manufacturer confirmation for specific application requirements.
