Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 103975-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (5)
• Pitch spacing (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge range (22-26 AWG)
• Contact finish material (Gold)
• Contact finish thickness (15.0µin / 0.38µm)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging / In-Line)
• Wire type (Ribbon Cable)
• Features (Closed End)
• Color (Black)
• Series designation (AMPMODU MTE)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL 1)
• Product status (Active)

The substitute part 5-103975-4 maintains full equivalence across all electrical and mechanical parameters. Differences in RoHS compliance status and REACH vendor definition do not affect functional interchangeability for applications where these certifications are not mandated.

Parameter Comparison

Engineering Selection Recommendations

Both the 103975-4 and 5-103975-4 are functionally equivalent rectangular receptacle connectors within the AMPMODU MTE series. Selection between these parts is determined by compliance and sourcing requirements rather than electrical or mechanical performance differences.

103975-4 Selection Criteria:

• Applications where RoHS compliance is not required
• Existing designs with established part number references
• Current inventory availability of 653 pieces

5-103975-4 Selection Criteria:

• Applications requiring RoHS Compliant certification
• Higher inventory availability (1195 pieces)
• New designs where RoHS compliance is mandated
• Applications requiring REACH compliance documentation

Both connectors operate identically with 5-position IDC termination, 22-26 AWG ribbon cable, gold-plated contacts, and MSL 1 moisture sensitivity rating. The choice between these parts does not affect connector performance, mating compatibility, or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 103975-4 and 5-103975-4 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 5-position configuration, 0.100" pitch, single-row layout, free-hanging in-line mounting, and closed-end design. They mate with identical plug connectors and ribbon cable assemblies.

Q: Can I substitute 5-103975-4 for 103975-4 in existing applications?

A: Yes. The 5-103975-4 maintains full electrical and mechanical equivalence. The primary difference is RoHS compliance status. If your application does not require RoHS certification, either part functions identically. If RoHS compliance is required, the 5-103975-4 is the appropriate selection.

Q: What is the difference in RoHS status between these parts?

A: The 103975-4 is marked as "Not applicable" for RoHS status, while the 5-103975-4 is "RoHS Compliant." This indicates the 5-103975-4 meets RoHS Directive 2011/65/EU requirements for restricted substances. Both parts are manufactured by TE Connectivity and operate identically.

Q: Do these connectors support the same wire gauge range?

A: Yes. Both the 103975-4 and 5-103975-4 terminate ribbon cable in the 22-26 AWG range using IDC (Insulation Displacement Contact) technology. Wire gauge compatibility is identical.

Q: What is the contact finish specification for these connectors?

A: Both connectors feature gold-plated contacts with a thickness of 15.0µin (0.38µm). This gold finish provides corrosion resistance and reliable electrical contact for ribbon cable termination.

Q: Are there inventory differences between these parts?

A: Yes. The 103975-4 has 653 pieces in stock, while the 5-103975-4 has 1195 pieces available. The 5-103975-4 offers higher inventory availability for immediate sourcing needs.

Q: Can I use these connectors in high-moisture environments?

A: Both connectors carry MSL 1 (Unlimited) moisture sensitivity rating, indicating they are not sensitive to moisture absorption during storage or handling. They are suitable for standard industrial environments without special moisture control requirements.

Q: What applications use 5-position IDC ribbon connectors?

A: These connectors are used in applications requiring ribbon cable interconnection such as data acquisition systems, industrial control panels, telecommunications equipment, and computer peripherals where IDC termination provides cost-effective assembly.
