Engineering Selection Recommendations

Tier 1 - Preferred Direct Substitutes:

The Molex 0395211006 is the primary equivalent for the TE Connectivity 796643-6. This part maintains identical pitch (0.197" / 5.00mm), shroud configuration (4-side), mounting type (through hole), current rating (15 A), voltage rating (300 V), and housing material (PA66, Nylon 6/6). The operating temperature range differs by 5°C (-40°C to 105°C versus -40°C to 110°C), which is within acceptable tolerance for most industrial applications. Both parts carry ROHS3 compliance and UL94 V-0 flammability rating. Inventory availability is 10,825 pieces.

Tier 2 - Pitch-Variant Substitutes (5.08mm):

The Amphenol PCD ELFH06250 provides a functionally equivalent solution with a pitch variant of 0.200" (5.08mm) instead of 0.197" (5.00mm). This part maintains 4-side shroud configuration, through-hole mounting, 15 A current rating, and 300 V voltage rating. The housing material differs (PBT versus PA66), and the operating temperature range is -40°C to 105°C. This substitute is suitable for applications where the 5.08mm pitch is acceptable within PCB layout constraints. Inventory availability is 1,146 pieces.

Tier 3 - Shroud-Variant Substitutes (2-Side):

The Phoenix Contact 1758050 and Amphenol Anytek OQ0653500000G both feature 2-side shroud configuration instead of 4-side. These parts maintain 0.200" (5.08mm) pitch, through-hole mounting, and 300 V voltage rating. Current ratings are 12 A, which is lower than the primary specification. The 2-side shroud provides reduced mechanical protection compared to 4-side configuration. These substitutes are applicable when board space constraints or design requirements permit reduced shroud coverage. Phoenix Contact 1758050 inventory is 989 pieces; Amphenol Anytek OQ0653500000G inventory is 2,954 pieces.

Tier 4 - Solder-Mount Variants:

The On Shore Technology Inc. OSTOQ067150 and EDSTL955/6 provide 5.00mm pitch equivalents with solder mounting instead of through-hole. These parts are suitable for applications requiring surface-mount or wave-solder assembly processes. The OSTOQ067150 maintains 4-side shroud configuration with 1,356 pieces in inventory. The EDSTL955/6 also maintains 4-side shroud with 996 pieces in inventory. Operating temperature ranges are -30°C to 105°C, which is narrower than the primary part.

Tier 5 - Combined Variant Substitutes:

The On Shore Technology Inc. EDSTLZ955/6 combines both pitch variant (5.08mm) and solder-mount configuration. This part maintains 4-side shroud and 300 V voltage rating with 1,979 pieces in inventory. Operating temperature range is -30°C to 105°C.

Compliance and Certification Status:

All substitute parts carry ROHS3 compliance or equivalent RoHS certification. All parts maintain 300 V UL voltage rating. Flammability ratings are UL94 V-0 where specified. All parts are active products with current manufacturing status.

Frequently Asked Questions (FAQ)

Q1: Can the Molex 0395211006 be used as a direct replacement for the TE Connectivity 796643-6?

A: Yes. The Molex 0395211006 is a direct functional equivalent. Both parts share identical pitch (0.197" / 5.00mm), 6-position configuration, 4-side shroud, through-hole mounting, 15 A current rating, 300 V voltage rating, and PA66 housing material. The operating temperature range differs by 5°C (-40°C to 105°C versus -40°C to 110°C), which is within acceptable tolerance for standard industrial applications. Both parts are ROHS3 compliant with UL94 V-0 flammability rating.

Q2: What is the difference between 5.00mm and 5.08mm pitch variants, and when should each be used?

A: The pitch is the center-to-center distance between adjacent positions. The 0.197" (5.00mm) pitch is the primary specification for the TE Connectivity 796643-6. The 0.200" (5.08mm) pitch represents a variant within industry standard tolerance. Selection depends on PCB layout design and connector footprint requirements. Parts with 5.08mm pitch include the Amphenol PCD ELFH06250, Phoenix Contact 1758050, and On Shore Technology Inc. EDSTLZ955/6. Verify PCB layout compatibility before substitution.

Q3: What is the functional difference between 4-side and 2-side shroud configurations?

A: The shroud is the plastic housing surrounding the connector positions. A 4-side shroud provides mechanical protection on all four sides of the connector, offering superior protection against accidental contact and environmental contamination. A 2-side shroud provides protection on two opposing sides only. The TE Connectivity 796643-6 features 4-side shroud. Substitutes with 2-side shroud (Phoenix Contact 1758050 and Amphenol Anytek OQ0653500000G) provide reduced mechanical protection and are suitable only when design requirements permit reduced shroud coverage.

Q4: Can solder-mount variants be used in applications designed for through-hole mounting?

A: No. Solder-mount variants (OSTOQ067150, EDSTL955/6, EDSTLZ955/6, OSTOQ065350) are designed for surface-mount or wave-solder assembly processes and are not compatible with through-hole PCB designs. The TE Connectivity 796643-6 is specified for through-hole mounting. Use only through-hole variants (Molex 0395211006, Phoenix Contact 1755558, Amphenol PCD ELFH06250, Amphenol Anytek OQ0653500000G, Phoenix Contact 1758050) for through-hole applications.

Q5: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance or equivalent RoHS certification status. The TE Connectivity 796643-6 is RoHS Compliant. All substitute parts maintain compliance with current RoHS directives.

Q6: What is the current rating difference between the primary part and some substitutes?

A: The TE Connectivity 796643-6 is rated for 15 A at UL specification. Some substitute parts, including Phoenix Contact 1755558, Phoenix Contact 1758050, and Amphenol Anytek OQ0653500000G, are rated for 12 A. The 12 A rating is lower and may not be suitable for applications requiring the full 15 A capacity. Verify current requirements before substitution. Parts with 15 A rating include Molex 0395211006 and Amphenol PCD ELFH06250.

Q7: What operating temperature range should be considered when selecting a substitute?

A: The TE Connectivity 796643-6 operates from -40°C to 110°C. Most substitute parts operate from -40°C to 105°C or -30°C to 105°C, representing a narrower range. For applications requiring operation at temperatures above 105°C or below -30°C, verify that the selected substitute meets the specific temperature requirements. The Amphenol Anytek OQ0653500000G extends to 115°C maximum, providing a wider upper temperature range.

Q8: What housing material differences exist among substitute parts?

A: The TE Connectivity 796643-6 uses Polyamide (PA66), Nylon 6/6 housing. Most substitutes use similar PA or Nylon materials. The Amphenol PCD ELFH06250 uses Polybutylene Terephthalate (PBT), which offers different mechanical and thermal properties. The Amphenol Anytek OQ0653500000G and On Shore Technology Inc. parts use Thermoplastic Resin or Thermoplastic materials. Material selection affects mechanical strength, temperature tolerance, and chemical resistance. Verify material compatibility with the application environment.

Q9: How should I verify compatibility before implementing a substitute part?

A: Compatibility verification requires confirmation of: (1) PCB footprint and pitch alignment, (2) mounting type compatibility (through-hole versus solder), (3) shroud configuration acceptance, (4) current and voltage rating sufficiency, (5) operating temperature range adequacy, (6) housing material compatibility with application environment, and (7) connector mating interface compatibility with existing mating connectors. Consult detailed datasheets and perform physical fit testing when possible.

Q10: What inventory considerations should guide substitute part selection?

A: Current inventory levels vary significantly among substitute parts. The Molex 0395211006 has the highest inventory at 10,825 pieces, followed by Amphenol Anytek OQ0653500000G at 2,954 pieces and On Shore Technology Inc. EDSTLZ955/6 at 1,979 pieces. The TE Connectivity 796643-6 has 833 pieces in stock. For applications requiring immediate availability, prioritize substitutes with higher inventory levels. For long-term supply chain planning, consider multiple qualified substitutes to mitigate single-source risk.
