Engineering Selection Recommendations

Direct Substitutes (0.197" / 5.00mm Pitch):

The Molex 0395211006 and Phoenix Contact 1755558 are direct pitch-compatible substitutes for the TE Connectivity 1776146-6. Both maintain the 0.197" (5.00mm) pitch spacing, 6-position configuration, vertical orientation, and 4-side shrouding. All three parts meet UL94 V-0 flammability requirements and 300 V voltage specifications. The Molex part supports 15 A current capacity (matching the main part), while the Phoenix Contact part is rated for 12 A. All parts are active products with RoHS3 compliance and MSL 1 rating.

Functional Alternatives (0.200" / 5.08mm Pitch):

The Molex 0395311006 and 0395316006, Phoenix Contact 1758050, Amphenol PCD ELFH06250, and Amphenol Anytek OQ0653500000G represent functional alternatives with 0.200" (5.08mm) pitch spacing. These parts maintain electrical specifications (300 V, UL94 V-0) and are suitable for applications where PCB layout accommodates the minor pitch variation. The Molex parts and Amphenol PCD ELFH06250 support 15 A current capacity. The Phoenix Contact 1758050 and Amphenol Anytek OQ0653500000G are rated for 12 A. Shroud configuration varies: Molex and Amphenol PCD provide 4-side shrouding; Phoenix Contact and Amphenol Anytek provide 2-side shrouding.

Compliance and Certification:

All substitute parts are active products with ROHS3 compliance or RoHS compliance status. All parts carry UL94 V-0 flammability ratings and 300 V UL voltage ratings. MSL ratings are consistent across all parts (MSL 1 or Not Applicable for Amphenol PCD ELFH06250). REACH status is either REACH Unaffected or Vendor Undefined, indicating no regulatory restrictions on substitution.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395211006 directly replace the TE Connectivity 1776146-6?

A: Yes. Both parts share identical pitch spacing (0.197" / 5.00mm), 6-position configuration, vertical orientation, 4-side shrouding, and electrical ratings (15 A, 300 V, UL94 V-0). Both are active products with equivalent compliance certifications.

Q: What is the difference between 0.197" (5.00mm) and 0.200" (5.08mm) pitch?

A: The pitch difference is 0.003" (0.08mm). This represents a minor industry-standard variation. Parts with 5.08mm pitch are not mechanically interchangeable with 5.00mm pitch parts on the same PCB without layout modification. Selection depends on PCB design specifications.

Q: Can I use a 12 A rated part where a 15 A part is specified?

A: No. Current rating is a critical electrical parameter. If the application requires 15 A capacity, parts rated for 12 A (Phoenix Contact 1755558, 1758050, and Amphenol Anytek OQ0653500000G) do not meet the specification and must not be substituted.

Q: What is the significance of 4-side versus 2-side shrouding?

A: Shroud configuration affects mechanical protection and EMI shielding. 4-side shrouding provides complete enclosure of the connector cavity. 2-side shrouding provides partial enclosure. Selection depends on application requirements for mechanical protection and electromagnetic compatibility. These configurations are not interchangeable without design review.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry either RoHS Compliant or ROHS3 Compliant status. All parts meet current RoHS regulatory requirements.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates Moisture Sensitivity Level 1, which means the component has unlimited shelf life under normal storage conditions and does not require special moisture-control handling during assembly. The Amphenol PCD ELFH06250 is rated as Not Applicable, indicating no moisture sensitivity restrictions.

Q: Can I substitute a part with a different operating temperature range?

A: Operating temperature range is an application-critical parameter. The main part is rated -40°C to 110°C. Substitute parts rated -40°C to 105°C are suitable for applications within the -40°C to 105°C window. The Amphenol Anytek OQ0653500000G, rated -40°C to 115°C, provides extended high-temperature capability. Selection must align with actual application temperature requirements.

Q: What contact material differences exist among substitute parts?

A: The main part uses copper alloy contacts. Molex parts use brass contacts. Phoenix Contact material is not specified. Amphenol PCD uses brass contacts. Amphenol Anytek uses copper alloy contacts. Contact material affects electrical conductivity and corrosion resistance. Brass and copper alloy are both acceptable for standard applications; selection depends on specific environmental and performance requirements.

Q: Are there inventory considerations for substitute selection?

A: Yes. Inventory levels vary significantly: TE Connectivity 1776146-6 has 705 units; Molex 0395211006 has 10,825 units; Molex 0395311006 has 14,953 units. Higher inventory availability may support faster procurement timelines for substitute parts.
