Engineering Selection Recommendations

1-487951-2 (Main Part):

RoHS non-compliant
REACH Affected
Contact finish: Tin-Lead (150.0µin / 3.81µm)
Current inventory: 678 units

1-84953-2 (Substitute):

RoHS3 Compliant
REACH status: Vendor Undefined
Contact finish: Tin (78.7µin / 2.00µm)
Current inventory: 3200 units

Both parts are active products from TE Connectivity AMP Connectors with identical electrical and mechanical specifications. The substitute part 1-84953-2 offers improved regulatory compliance with RoHS3 certification and significantly higher inventory availability. Selection between these parts should be based on regulatory requirements of the end application and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Are the 1-487951-2 and 1-84953-2 electrically interchangeable?

A: Yes. Both connectors maintain identical voltage ratings (200V), current ratings (1A), and operating temperature ranges (-40°C to 85°C). Electrical performance is equivalent.

Q: Are the 1-487951-2 and 1-84953-2 mechanically interchangeable?

A: Yes. Both connectors feature identical 12-position configurations, 1.00mm pitch spacing, surface mount right-angle orientation, and 0.101" height above board. PCB footprints and mounting requirements are identical.

Q: What is the difference in contact finish between these parts?

A: The 1-487951-2 uses Tin-Lead finish (150.0µin thickness), while the 1-84953-2 uses Tin finish (78.7µin thickness). Both finishes provide equivalent electrical conductivity and solder joint reliability for this connector application.

Q: Why does the 1-84953-2 have higher inventory availability?

A: The 1-84953-2 carries RoHS3 compliance certification, making it suitable for a broader range of applications and markets. This expanded applicability typically results in higher production volumes and inventory levels.

Q: Can I use the 1-84953-2 as a direct replacement in an existing design?

A: Yes. The 1-84953-2 is a direct substitute with identical mechanical and electrical specifications. No design modifications are required for PCB layout, schematic, or assembly processes.

Q: What is the significance of the RoHS compliance difference?

A: The 1-487951-2 is RoHS non-compliant, while the 1-84953-2 is RoHS3 compliant. Applications subject to RoHS regulations or customer requirements must use the 1-84953-2. Applications without such restrictions may use either part.

Q: Are the packaging formats identical?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging format, ensuring compatibility with standard pick-and-place assembly equipment.
