TE Connectivity 1586940-1 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1586940-1 is a 2-position rectangular connector plug housing from the Universal MATE-N-LOK series. This component is classified as Obsolete, indicating discontinued manufacturing and limited availability for new applications. The part functions as a housing for male or female crimp contacts in free-hanging inline configurations, designed for applications requiring latch lock fastening and operating across the -55°C to 105°C temperature range.

Due to its obsolete status, identifying equivalent substitute parts is necessary for ongoing maintenance, repair, and new design implementations where the original part is no longer procurable through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1586940-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug
• Number of Positions: 2
• Number of Rows: 2
• Row Spacing: 0.163" (4.14mm)
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Insulation Material: Polyamide (PA), Nylon
• Operating Temperature Range: -55°C ~ 105°C
• Color: Natural

The substitute part 794184-1 satisfies all mandatory matching parameters. While it belongs to the Mini-Universal MATE-N-LOK II series (compared to the Universal MATE-N-LOK series of the original part), the electrical and mechanical specifications remain equivalent. The primary distinction is the product status: 794184-1 is Active, whereas 1586940-1 is Obsolete.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 794184-1

The 794184-1 is the direct functional equivalent for applications currently using or requiring the 1586940-1. Selection of 794184-1 is supported by the following engineering factors:

Product Status: The 794184-1 maintains Active product status, ensuring continued availability, manufacturing support, and compliance with current industry standards. The 1586940-1, classified as Obsolete, presents supply chain risk and lacks ongoing manufacturer support.

Regulatory Compliance: Both parts maintain equivalent compliance certifications. The 794184-1 carries RoHS Compliant status, while the 1586940-1 carries ROHS3 Compliant status. Both satisfy environmental and hazardous substance restrictions applicable to rectangular connector housings.

Electrical and Mechanical Equivalence: All critical parameters—connector type, position count, row configuration, row spacing, mounting method, contact termination, fastening mechanism, insulation material, and operating temperature range—are identical between the two parts. This equivalence ensures direct functional substitution without circuit redesign or mechanical rework.

Inventory Availability: The 794184-1 maintains significantly higher inventory levels (9,225 pieces) compared to the 1586940-1 (795 pieces), supporting long-term procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the 794184-1 directly replace the 1586940-1 in existing assemblies?

A: Yes. The 794184-1 is mechanically and electrically equivalent to the 1586940-1 across all specified parameters. Both parts accept identical crimp contacts, maintain the same row spacing and mounting configuration, and operate within the same temperature range. Direct substitution is supported without modification to mating connectors or contact specifications.

Q: What is the difference between the Universal MATE-N-LOK and Mini-Universal MATE-N-LOK II series?

A: The series designation reflects product line evolution within TE Connectivity's connector portfolio. However, the 1586940-1 and 794184-1 maintain identical electrical and mechanical specifications for the 2-position, 2-row configuration. The series difference does not affect functional compatibility or performance characteristics.

Q: Are the contacts interchangeable between these two housing parts?

A: Yes. Both housings accept crimp contacts designed for the MATE-N-LOK connector family with 0.163" (4.14mm) row spacing. Contact specifications are determined by the contact part number, not the housing series designation. Verify contact part numbers independently to ensure compatibility with your application requirements.

Q: What is the significance of the different packaging specifications?

A: The 1586940-1 is listed with unspecified packaging, while the 794184-1 is supplied in Bulk packaging. Packaging differences do not affect the electrical or mechanical performance of the connector housing. Packaging selection is determined by procurement volume and inventory management requirements.

Q: Why is the 1586940-1 classified as Obsolete?

A: Obsolete classification indicates that TE Connectivity has discontinued manufacturing of this part number. The 794184-1 represents the current active product offering that fulfills the same functional requirements. For new designs and ongoing procurement, the 794184-1 is the appropriate selection.

Q: Are there any temperature or environmental limitations when substituting the 794184-1?

A: No. Both parts operate across the identical temperature range of -55°C to 105°C and maintain equivalent moisture sensitivity levels (MSL 1 - Unlimited). Environmental performance characteristics are equivalent.

Q: What compliance certifications apply to both parts?

A: Both parts carry RoHS compliance certifications and are classified under ECCN EAR99 for export control purposes. The 1586940-1 carries ROHS3 Compliant status, while the 794184-1 carries RoHS Compliant status. Both satisfy current environmental and hazardous substance regulations applicable to rectangular connector housings.
