TE Connectivity 794550-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 794550-6 is a 6-position rectangular connector plug housing with 0.165" (4.20mm) pitch, designed for panel mount snap-in applications with crimp contact termination. This component belongs to the AMP-DUAC series and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary for ongoing design support, maintenance, and production continuity. Substitute parts maintain the same electrical and mechanical specifications while offering active product status or improved availability.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 794550-6 is determined by strict equivalence across the following critical parameters: connector type (plug), contact type (male pin), number of positions (6), pitch (0.165"/4.20mm), number of rows (2), row spacing (0.165"/4.20mm), mounting type (panel mount, snap-in), contact termination (crimp), and fastening type (locking ramp).

Substitute parts are grouped into two categories:

Category 1: TE Connectivity AMP-DUAC and VAL-U-LOK Series — Parts 794953-6, 1586018-6, 1969599-6, 1969613-6, and 1969605-6 maintain identical mechanical and electrical specifications. These parts differ primarily in series designation, product status, and insulation material composition (polyamide PA or PA66 nylon variants). All operate within the -40°C to 105°C temperature range and comply with RoHS3 standards.

Category 2: Molex Mini-Fit Jr 5559 Series — Parts 0039012061 and 0469990295 provide parametric equivalence across all critical dimensions and electrical characteristics. The primary distinction is color: 0039012061 is natural, while 0469990295 is black. Both maintain the same pitch, position count, mounting configuration, and termination method.

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity VAL-U-LOK Series):

Parts 794953-6, 1586018-6, 1969613-6, and 1969605-6 are recommended as primary substitutes. All four maintain active product status, ensuring long-term availability and supply chain continuity. Parts 1969613-6 and 1969605-6 carry ROHS3 compliance identical to the original 794550-6, providing direct regulatory alignment. Part 794953-6 offers the highest inventory availability (11,083 units) among TE Connectivity options. Part 1586018-6 provides an alternative within the VAL-U-LOK series with 3,790 units in stock.

Secondary Substitutes (TE Connectivity VAL-U-LOK Obsolete):

Part 1969599-6 maintains obsolete status but offers ROHS3 compliance and 5,907 units in inventory. This part is suitable for applications where existing stock management or legacy system compatibility is prioritized.

Cross-Manufacturer Substitutes (Molex Mini-Fit Jr 5559 Series):

Part 0039012061 (natural color) provides parametric equivalence with active product status and the highest overall inventory availability (47,515 units). This part is suitable for applications where cross-manufacturer compatibility is acceptable and supply security is critical.

Part 0469990295 (black color) offers the same electrical and mechanical specifications as 0039012061 but with black insulation. This part is appropriate only when color specification permits black housing.

Compliance Considerations:

All substitute parts comply with RoHS3 standards. TE Connectivity parts carry REACH Unaffected or Vendor Undefined status; Molex parts carry REACH Unaffected status. All parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can 794953-6 directly replace 794550-6 in existing designs?

A: Yes. Part 794953-6 maintains identical electrical and mechanical specifications across all critical parameters: 6 positions, 0.165" pitch, 2-row configuration, panel mount snap-in mounting, crimp termination, and locking ramp fastening. The primary difference is series designation (VAL-U-LOK versus AMP-DUAC) and active product status.

Q: What is the difference between TE Connectivity VAL-U-LOK parts (794953-6, 1586018-6, 1969613-6, 1969605-6)?

A: All four parts share identical connector specifications. Differences exist in insulation material composition (polyamide PA or PA66 nylon variants), product status (active or obsolete), and inventory availability. Parts 1969613-6 and 1969605-6 specify PA66 nylon 6/6 insulation, while 794953-6 and 1969605-6 specify polyamide PA nylon. All operate within -40°C to 105°C temperature range.

Q: Can Molex 0039012061 be used as a substitute for TE Connectivity 794550-6?

A: Yes. Part 0039012061 maintains parametric equivalence across all critical specifications: 6 positions, 0.165" pitch, 2-row configuration, panel mount snap-in mounting, crimp termination, and locking ramp fastening. Cross-manufacturer substitution is valid when connector interface compatibility is confirmed in the application circuit.

Q: Why is 0469990295 listed as a substitute if it is black instead of natural?

A: Part 0469990295 maintains identical electrical and mechanical specifications to 794550-6 across all functional parameters. Color difference (black versus natural) is a cosmetic distinction that does not affect electrical performance or mechanical compatibility. This part is suitable only for applications where black housing is acceptable or preferred.

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

A: Active product status indicates ongoing manufacturer support, continued production, and long-term supply availability. Obsolete status indicates discontinued production. For new designs or long-term production requirements, active parts (794953-6, 1586018-6, 1969613-6, 1969605-6, 0039012061) are preferred. Obsolete parts (794550-6, 1969599-6) are suitable for maintenance and repair of existing systems where legacy component compatibility is required.

Q: Are contacts included with these connector housings?

A: No. All listed parts specify "Contacts Not Included." Contacts must be sourced separately and selected to match the 0.165" (4.20mm) pitch specification and crimp termination requirement.

Q: What is the difference between ROHS3 Compliant and RoHS Compliant designations?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 Compliant indicates compliance with the most current RoHS 3 directive. RoHS Compliant indicates compliance with earlier RoHS standards. For regulatory alignment with current standards, parts carrying ROHS3 designation (794550-6, 1969599-6, 1969613-6, 1969605-6, 0039012061, 0469990295) are preferred.

Q: Can these connector housings be used in high-temperature applications?

A: All substitute parts operate within the -40°C to 105°C temperature range. Applications requiring operation outside this range require alternative connector housing selection.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and requires no special moisture control during storage, handling, or assembly. This classification applies to all listed parts.
