Engineering Selection Recommendations

The substitute part 3-1489841-0 is functionally equivalent to the 2-1489841-9 across all critical electrical and mechanical parameters. The primary distinction is product status: the main part is classified as obsolete, while the substitute is active.

Compliance Considerations:

Both parts maintain RoHS compliance (ROHS3 for 2-1489841-9; RoHS for 3-1489841-0)
Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications
Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints
REACH status differs (REACH Unaffected for 2-1489841-9; Vendor Undefined for 3-1489841-0)

Selection Basis:

For new designs or component replenishment, the 3-1489841-0 is the appropriate selection due to its active product status and confirmed availability. For legacy system maintenance where the original 2-1489841-9 is required, both parts maintain identical form, fit, and function characteristics, with the only cosmetic difference being connector color (Black versus Natural).

Frequently Asked Questions (FAQ)

Q: Are the 2-1489841-9 and 3-1489841-0 mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (through-hole), position count (240), card thickness (0.050"), and mounting feature orientation (Normal, Standard - Top). They occupy the same PCB footprint and require identical assembly processes.

Q: What is the functional difference between these two parts?

A: There is no functional difference. Both are 240 Position DIMM DDR2 SDRAM sockets with identical electrical specifications, contact finish (gold at 30.0µin), and mechanical features (board lock and latches).

Q: Why does the color differ between the two parts?

A: The 2-1489841-9 features a black connector body, while the 3-1489841-0 features a natural-colored body. This is a cosmetic distinction only and does not affect electrical performance or mechanical compatibility.

Q: Can I use the 3-1489841-0 as a direct replacement for the 2-1489841-9 in existing designs?

A: Yes. The 3-1489841-0 maintains identical specifications for all critical parameters: connector style, position count, memory type, mounting type, features, and contact specifications. Direct substitution is supported without design modification.

Q: What is the significance of the product status difference?

A: The 2-1489841-9 is classified as obsolete, indicating it is no longer in active production. The 3-1489841-0 is active, meaning it is currently manufactured and available for procurement. For new applications, the active part is the standard selection.

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant and carry identical export classifications (ECCN: EAR99). The REACH status differs slightly (REACH Unaffected versus Vendor Undefined), but both parts meet regulatory requirements for their respective applications.

Q: What is the MSL rating, and does it affect storage or handling?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard component storage and handling procedures apply without special environmental controls.
