Substitute Part Grouping Explanation

Substitution between the main part 1-643815-0 and the equivalent part 4-643815-0 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

Connector type (Receptacle)
Number of positions (10)
Contact type (Female Socket)
Pitch (0.100" / 2.54mm)
Number of rows (1)
Cable termination method (IDC)
Wire gauge (26 AWG)

Mechanical Compatibility Parameters:

Mounting type (Free Hanging In-Line, Right Angle)
Fastening type (Locking Ramp)
Features (Closed End)
Contact finish thickness (80.0µin / 2.03µm)
Color (Blue)
Series designation (MTA-100)

Both parts share identical electrical and mechanical specifications. The primary distinction lies in contact finish composition and packaging configuration, which do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

Part 1-643815-0 Selection Criteria:

Applications requiring tin-lead contact finish where RoHS compliance is not a design constraint
Standard packaging requirements
Existing designs with established tin-lead specifications

Part 4-643815-0 Selection Criteria:

Applications requiring RoHS Compliant components
Bulk packaging requirements for high-volume manufacturing
New designs targeting environmental compliance standards
Applications where tin-only contact finish is acceptable

Both parts maintain Active product status and identical electrical and mechanical specifications. The 4-643815-0 offers superior supply availability with 4385 units in stock compared to 902 units for the 1-643815-0. Selection between these parts should be based on compliance requirements, packaging needs, and supply chain considerations rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 1-643815-0 and 4-643815-0 electrically interchangeable?

A: Yes. Both parts are electrically identical, featuring 10 positions, 0.100" pitch, IDC termination, 26 AWG wire gauge, and female socket contacts. They function identically in circuit applications.

Q: What is the difference between tin-lead and tin contact finish?

A: The 1-643815-0 features tin-lead contact finish, while the 4-643815-0 features tin-only finish. Both maintain 80.0µin (2.03µm) thickness. The tin-only finish in the 4-643815-0 provides RoHS compliance, whereas the tin-lead finish in the 1-643815-0 is not RoHS applicable.

Q: Can I use the 4-643815-0 as a direct replacement for the 1-643815-0?

A: Direct replacement is possible from a mechanical and electrical standpoint. However, design documentation and compliance requirements must be reviewed. If the original design specifies tin-lead finish or non-RoHS components, substitution to tin-only finish requires design verification.

Q: What does "Bulk" packaging mean for the 4-643815-0?

A: Bulk packaging indicates the part is supplied in larger quantities without individual packaging, typically used for high-volume manufacturing operations. Standard packaging for the 1-643815-0 may include individual or smaller quantity containers.

Q: Are both parts suitable for ribbon cable applications?

A: Yes. Both the 1-643815-0 and 4-643815-0 support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 26 AWG wire gauge.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special moisture control measures.

Q: Which part should I select for new designs?

A: For new designs, the 4-643815-0 is recommended due to RoHS compliance status and superior inventory availability (4385 units versus 902 units). This part meets modern environmental standards and provides better supply chain security.
