Engineering Selection Recommendations

Primary Selection: TE Connectivity 1776149-9

The TE Connectivity 1776149-9 is the recommended direct substitute for the obsolete 282963-9. This part maintains identical electrical specifications (15 A at 300 V), mechanical configuration (9 positions, 0.295" pitch, vertical through-hole), and physical dimensions (0.138" contact tail length, 0.472" insulation height). The 1776149-9 carries active product status and RoHS compliance, ensuring long-term availability and regulatory alignment for new designs and production runs.

Secondary Selection: Weidmüller 1629090000

The Weidmüller 1629090000 provides functional compatibility with the 282963-9 while offering active product status and RoHS compliance. This part maintains the identical 0.295" (7.50mm) pitch and 9-position vertical through-hole configuration. The primary design consideration is the reduced contact tail length (0.126" versus 0.138"), which requires PCB layout verification to confirm solder joint depth compatibility. The PBT housing material meets the same UL94 V-0 flammability requirement as the original part.

Tertiary Selection: Weidmüller 1629200000

The Weidmüller 1629200000 offers the same electrical and pitch specifications as the 1629090000 but features 4-side shrouding instead of 2-side shrouding. This configuration provides enhanced mechanical protection and EMI shielding. The same contact tail length consideration (0.126" versus 0.138") applies. Selection of this part is appropriate when increased shrouding is beneficial to the application design.

Alternative Selection: Weidmüller 1625320000

The Weidmüller 1625320000 is functionally compatible but features a slightly larger pitch (0.300" or 7.62mm versus 0.295" or 7.50mm) and 4-side shrouding. This part is suitable only when PCB layout can accommodate the pitch variation and when the enhanced shrouding configuration is required. The contact tail length (0.126") also differs from the original specification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1776149-9 be used as a direct replacement for the 282963-9?

A: Yes. The 1776149-9 maintains identical electrical ratings (15 A at 300 V), mechanical configuration (9 positions, 0.295" pitch, vertical through-hole), and physical dimensions (0.138" contact tail length, 0.472" insulation height). The only difference is product status (active versus obsolete) and RoHS compliance, both of which favor the 1776149-9 for new production.

Q: What is the significance of the contact tail length difference between the 282963-9 and Weidmüller parts?

A: The 282963-9 has a contact tail length of 0.138" (3.50mm), while Weidmüller parts have 0.126" (3.20mm). This 0.012" (0.30mm) difference affects solder joint depth on the PCB. PCB design must be verified to ensure adequate solder fillet formation and mechanical strength. Existing PCB designs may require modification to accommodate the shorter tail length.

Q: Are the Weidmüller parts RoHS compliant?

A: Yes. All Weidmüller substitute parts (1629090000, 1629200000, 1625320000) carry RoHS compliance status. The original TE Connectivity 282963-9 is marked as "Not applicable" for RoHS status due to its obsolete classification.

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

A: The 282963-9 and 1629090000 feature 2-side shrouding, which provides protection on two opposing sides. The 1629200000 and 1625320000 feature 4-side shrouding, which provides protection on all four sides. Four-side shrouding offers enhanced mechanical protection and improved EMI shielding characteristics. Selection depends on application requirements for mechanical robustness and electromagnetic compatibility.

Q: Can the Weidmüller 1625320000 be used if the PCB layout is designed for 0.295" pitch?

A: The 1625320000 features a 0.300" (7.62mm) pitch, which is 0.005" (0.127mm) larger than the 0.295" (7.50mm) pitch of the 282963-9. This difference requires PCB layout modification. Direct substitution without PCB redesign is not possible. The 1629090000 or 1629200000 are preferred alternatives as they maintain the 0.295" pitch specification.

Q: What is the operating temperature range difference between the main part and substitutes?

A: The 282963-9 operates from -40°C to 110°C. The Weidmüller parts (1629090000, 1629200000, 1625320000) operate from -50°C to 100°C. The lower temperature limit is extended (-50°C versus -40°C), but the upper temperature limit is reduced (100°C versus 110°C). Application thermal requirements must be evaluated to confirm compatibility.

Q: Are all substitute parts available in the same color as the original?

A: No. The 282963-9 is green, while the TE Connectivity 1776149-9 is black. The Weidmüller parts are orange. Color differences are cosmetic and do not affect electrical or mechanical function. If color coding is required for application identification or traceability, this must be addressed through alternative marking methods.

Q: What is the current rating difference between IEC and UL standards?

A: The 282963-9 specifies only a UL current rating of 15 A. The Weidmüller parts specify both IEC (18.5 A) and UL (15 A) ratings. The UL rating of 15 A is the limiting specification for applications requiring UL compliance. The higher IEC rating does not increase the usable current capacity in UL-regulated applications.
