TE Connectivity 103957-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103957-5 is a 6-position rectangular receptacle connector from the AMPMODU MTE series, designed for IDC (Insulation Displacement Contact) termination with 22-26 AWG wire. This connector features gold-plated female socket contacts, a 0.100" pitch, and latch lock fastening for secure in-line applications.

The 103957-5 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives. Active substitute parts are available within the same product family, offering identical electrical and mechanical specifications with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 103957-5 are identified based on strict electrical and mechanical parameter matching within the AMPMODU MTE series. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 6
• Pitch: 0.100" (2.54mm)
• Mounting type: Free hanging (in-line)
• Fastening type: Latch lock
• Cable termination: IDC
• Wire gauge range: 22-26 AWG
• Contact finish: Gold at 15.0µin thickness
• Closed end configuration
• Color: Black

All substitute parts listed maintain identical specifications across these parameters, ensuring direct functional equivalence in applications requiring 6-position IDC receptacle connectors with gold contacts and latch lock fastening.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5-103957-5

The 5-103957-5 is the preferred substitute for the discontinued 103957-5. This part maintains complete electrical and mechanical equivalence while offering improved compliance status. The 5-103957-5 is RoHS compliant and currently active in production, with the highest inventory availability (3402 units). Tube packaging is standard for this variant.

Secondary Substitute: 1-103957-6

The 1-103957-6 provides an alternative substitute with identical functional specifications. This part is ROHS3 compliant and active in production. Inventory availability is 1085 units in tube packaging. Selection between 1-103957-6 and 5-103957-5 depends on specific compliance requirements and packaging preferences, as both parts are electrically and mechanically interchangeable.

Compliance Considerations

The original 103957-5 is RoHS non-compliant. Applications requiring RoHS compliance must transition to either 5-103957-5 (RoHS Compliant) or 1-103957-6 (ROHS3 Compliant). Both substitutes meet current regulatory requirements while maintaining identical connector specifications.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 1-103957-6 and 5-103957-5 directly interchangeable with 103957-5?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications, including connector type, contact configuration, pitch, wire gauge compatibility, and contact finish. Direct substitution is supported without circuit or assembly modifications.

Q: What is the difference between 1-103957-6 and 5-103957-5?

A: Both parts are functionally equivalent. The primary differences are RoHS certification status (1-103957-6 is ROHS3 compliant; 5-103957-5 is RoHS compliant) and inventory availability (5-103957-5 has higher stock levels at 3402 units versus 1085 units). Packaging for both is tube format.

Q: Why is the original 103957-5 discontinued?

A: The 103957-5 is discontinued at DiGi Electronics. The substitute parts 1-103957-6 and 5-103957-5 are active production variants within the same AMPMODU MTE series, offering improved compliance and continued availability.

Q: Can I use these connectors with both discrete and ribbon cable?

A: Yes. All three parts support both discrete and ribbon cable termination via IDC (Insulation Displacement Contact) technology, with wire gauge compatibility of 22-26 AWG.

Q: What is the pitch specification, and why does it matter?

A: The pitch is 0.100" (2.54mm), representing the center-to-center distance between adjacent contact positions. This specification is critical for mechanical compatibility with mating connectors and PCB layouts. All substitute parts maintain identical pitch.

Q: Are there packaging differences between the parts?

A: The original 103957-5 packaging is not specified. Both substitute parts (1-103957-6 and 5-103957-5) are supplied in tube packaging, which is standard for this connector series.

Q: What does the latch lock fastening type provide?

A: Latch lock fastening ensures secure mechanical connection between the receptacle and mating plug connector. This feature is maintained across all three parts.

Q: Is the closed end feature important for my application?

A: The closed end configuration prevents accidental contact exposure and provides strain relief. This feature is consistent across all three parts and is standard for this connector series.
