Engineering Selection Recommendations

Molex 0395016020 is the primary substitute for the TE Connectivity 2-284515-0. This part maintains identical pitch, position count, and voltage specifications while offering active product status and ROHS3 compliance. The green color matches the original part, and the 4-side shrouding provides enhanced mechanical protection compared to the 2-side shrouding of the original. The 8 A current rating is suitable for applications not exceeding this threshold. Operating temperature range of -40°C to 105°C covers most industrial applications, with the exception of the original part's extended upper limit of 110°C.

Molex 0395011020 serves as an alternative substitute with identical electrical and mechanical specifications to the 0395016020, differentiated only by black housing color. This part is appropriate for applications where color coding is not a design requirement.

Assmann WSW A-TB350-OQ20CV provides a secondary substitute option with active product status and ROHS3 compliance. This part features a 10 A current rating, closer to the original 11 A specification, and maintains green housing color. The operating temperature range of -30°C to 105°C is narrower at the lower limit compared to the original -40°C specification. Contact tail length of 0.138" (3.50mm) matches the pitch dimension exactly, providing optimal PCB compatibility.

All three substitute parts carry UL94 V-0 flammability ratings, tin contact mating finish, and MSL 1 moisture sensitivity classification, ensuring compliance with the original part's safety and reliability specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395016020 directly replace the TE Connectivity 2-284515-0 in existing designs?

A: The Molex 0395016020 is mechanically and electrically compatible for through-hole PCB mounting. The 4-side shrouding of the Molex part provides additional mechanical protection compared to the 2-side shrouding of the original. Contact tail length variation (0.140" vs. 0.134") is within acceptable PCB hole tolerance ranges. Verification of current requirements is necessary; applications requiring sustained currents above 8 A require the Assmann WSW A-TB350-OQ20CV (10 A rating) or design modification.

Q: What is the significance of the shrouding difference between 2-side and 4-side configurations?

A: Both 2-side and 4-side shrouding provide electrical isolation between adjacent pins. The 4-side shrouding of the substitute parts offers enhanced mechanical robustness and improved resistance to lateral insertion forces. Electrical performance and voltage isolation characteristics remain equivalent at the 300 V UL rating.

Q: Are there temperature range limitations when substituting with active parts?

A: The original TE Connectivity 2-284515-0 operates from -40°C to 110°C. The Molex parts (0395011020 and 0395016020) operate from -40°C to 105°C, providing a 5°C reduction in maximum operating temperature. The Assmann WSW A-TB350-OQ20CV operates from -30°C to 105°C, reducing the minimum operating temperature by 10°C. Applications requiring operation below -30°C or above 105°C require design review.

Q: What is the impact of contact material differences (phosphor bronze vs. brass)?

A: Both phosphor bronze and brass provide equivalent electrical conductivity and contact resistance characteristics for this application. Brass is the standard contact material in the substitute parts and offers equivalent performance in solder termination applications. No functional difference exists for signal integrity or power delivery.

Q: Are all substitute parts RoHS compliant?

A: The original TE Connectivity 2-284515-0 is marked as "Not applicable" for RoHS status. All three substitute parts are ROHS3 compliant, meeting current environmental regulations for new designs and production. This compliance status does not affect electrical or mechanical compatibility.

Q: What packaging considerations apply to these substitute parts?

A: The original part is listed with unspecified packaging. All substitute parts are supplied in bulk packaging. Inventory availability is confirmed for all three alternatives: Molex 0395011020 (929 pcs), Molex 0395016020 (900 pcs), and Assmann WSW A-TB350-OQ20CV (959 pcs).

Q: Can the Assmann WSW A-TB350-OQ20CV be used in applications requiring 11 A current?

A: The Assmann WSW A-TB350-OQ20CV is rated for 10 A UL current, which is below the original part's 11 A specification. This part is suitable for applications with sustained currents up to 10 A. Applications requiring the full 11 A rating must retain the original part or implement design modifications to reduce current requirements.
