Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 103956-8 is determined by maintaining strict equivalence across the following critical parameters:

• Connector Configuration: 9-position receptacle with female socket contacts
• Pitch and Spacing: 0.100" (2.54mm) pitch, single row configuration
• Termination Technology: IDC cable termination for 22-26 AWG discrete wire
• Mechanical Interface: Free hanging in-line mounting with latch lock fastening
• Contact Finish Thickness: 100.0µin (2.54µm) plating thickness

The substitute part 5-103956-8 maintains all electrical and mechanical parameters identical to the main part. The primary distinction is the contact finish specification: the main part features tin-lead plating, while the substitute features tin plating. Both finishes meet the specified thickness requirement and support equivalent electrical performance. The substitute part additionally carries ROHS3 compliance certification, whereas the main part is not applicable for RoHS classification.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 103956-8 and its substitute 5-103956-8 are classified as Active products and are suitable for new design implementations. The selection between these parts should be based on the following criteria:

103956-8 (Tin-Lead Contact Finish): This part is appropriate for applications where tin-lead plating is explicitly specified or required by design documentation. The part maintains full electrical and mechanical compatibility with the AMPMODU MTE series ecosystem.

5-103956-8 (Tin Contact Finish, ROHS3 Compliant): This substitute part is the preferred selection for applications subject to RoHS3 compliance requirements or when lead-free contact finishes are mandated by regulatory or customer specifications. The tin contact finish maintains the specified 100.0µin (2.54µm) thickness and delivers equivalent electrical performance. This part offers superior inventory availability with 1148 units in stock compared to 834 units for the main part.

Both parts support identical wire gauge ranges (22-26 AWG), pitch specifications (0.100"), and IDC termination methodology. The contact finish distinction does not affect mechanical interface compatibility or electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5-103956-8 substitute directly replace the 103956-8 in existing designs?

A: Yes. The 5-103956-8 maintains identical electrical and mechanical specifications including connector type, position count, pitch, wire gauge range, mounting configuration, and contact finish thickness. The contact finish material differs (tin versus tin-lead), but both finishes meet the specified 100.0µin (2.54µm) thickness requirement and deliver equivalent electrical performance.

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

A: The primary difference is the contact finish material. The 103956-8 features tin-lead plating, while the 5-103956-8 features tin plating. Additionally, the 5-103956-8 carries ROHS3 compliance certification, whereas the 103956-8 is not applicable for RoHS classification.

Q: Are both parts compatible with 22-26 AWG discrete wire?

A: Yes. Both the 103956-8 and 5-103956-8 are specified for IDC termination of discrete wire in the 22-26 AWG range. The wire gauge compatibility is identical across both parts.

Q: What does the 0.100" (2.54mm) pitch specification mean?

A: The pitch specification defines the center-to-center distance between adjacent contact positions. Both parts maintain a 0.100" (2.54mm) pitch in a single-row configuration, ensuring mechanical and electrical compatibility with mating connectors designed for this spacing.

Q: Does the contact finish thickness affect substitutability?

A: No. Both parts specify an identical contact finish thickness of 100.0µin (2.54µm). This thickness is maintained regardless of whether the finish material is tin-lead or tin, ensuring equivalent electrical performance and corrosion resistance characteristics.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS3 compliance requirements, the 5-103956-8 is the appropriate selection. For applications without RoHS compliance mandates, either part is suitable based on design specifications and contact finish requirements. The 5-103956-8 offers higher inventory availability.

Q: Are both parts available in tube packaging?

A: Yes. Both the 103956-8 and 5-103956-8 are supplied in tube packaging, maintaining consistent handling and storage requirements.

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

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.
