Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 103959-9 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Number of positions (10)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (1)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge compatibility (26-30 AWG)
• Mounting configuration (Free Hanging In-Line)
• Fastening mechanism (Latch Lock)
• Contact finish thickness (100.0µin / 2.54µm)
• Color (Black)
• Series designation (AMPMODU MTE)

The substitute part 5-103959-9 maintains full equivalence across all mandatory parameters. The primary distinction between the main part and its substitute relates to contact finish composition and product status classification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Active Production or New Designs:

The 5-103959-9 is the appropriate selection. This part maintains full electrical and mechanical compatibility with the 103959-9 while offering active product status and RoHS compliance. The transition from Tin-Lead to Tin contact finish does not affect the electrical performance or mechanical interface characteristics. The 5-103959-9 is currently in active inventory and supported by the manufacturer.

For Legacy System Maintenance:

The 103959-9 remains available in inventory (1052 pieces) for applications requiring exact historical specification compliance, including Tin-Lead contact finish. However, the 5-103959-9 provides functional equivalence for repair and maintenance scenarios where RoHS compliance is required or preferred.

Compliance Considerations:

The 103959-9 is RoHS non-compliant and REACH-affected. The 5-103959-9 is RoHS compliant with undefined REACH status. Both parts share the same ECCN classification (EAR99) and HTSUS code (8536.69.8000).

Frequently Asked Questions (FAQ)

Q: Can the 5-103959-9 be used as a direct replacement for the 103959-9?

A: Yes. The 5-103959-9 provides full functional equivalence. Both connectors share identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact type, termination method, and wire gauge compatibility. The primary differences are product status and contact finish composition.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The 103959-9 features Tin-Lead contact finish, while the 5-103959-9 features Tin contact finish. Both maintain the same contact finish thickness of 100.0µin (2.54µm). The contact finish composition does not affect the mechanical interface or electrical performance in this connector application.

Q: Why is the 103959-9 marked as obsolete?

A: The 103959-9 carries obsolete product status, indicating it is no longer in active production. The 5-103959-9 represents the current active equivalent within the AMPMODU MTE series.

Q: Are there packaging differences between these parts?

A: The 103959-9 packaging is not specified in the available data. The 5-103959-9 is packaged in Tube format.

Q: What is the MSL rating for these connectors?

A: Both the 103959-9 and 5-103959-9 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity limitations.

Q: Can these connectors accommodate both discrete and ribbon cable?

A: Yes. Both the 103959-9 and 5-103959-9 support discrete or ribbon cable termination via IDC method with wire gauge range 26-30 AWG.

Q: Are these connectors suitable for in-line applications?

A: Yes. Both connectors feature free-hanging in-line mounting type with latch lock fastening, suitable for direct cable integration without additional mounting hardware.
