TE Connectivity 103976-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 103976-6 is a 7-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector features gold-plated female socket contacts rated for 22-26 AWG wire gauges and operates as a free-hanging in-line component with a closed-end design.

The 103976-6 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing system support, maintenance, and new design implementations. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 103976-6 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish direct substitutability:

Critical Matching Parameters:

• Connector type: Rectangular receptacle configuration
• Position count: 7 positions
• Contact gender: Female socket
• Pitch spacing: 0.100" (2.54mm)
• Row configuration: Single row
• Termination method: IDC technology
• Wire compatibility: Ribbon cable, 22-26 AWG
• Contact material and finish: Gold plating at 30.0µin thickness
• Mounting configuration: Free hanging in-line
• Closed-end design requirement

Parts meeting all specified parameters are classified as direct equivalents and may be substituted without circuit redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The 5-103976-6 is a direct functional equivalent to the obsolete 103976-6 part number. All electrical and mechanical parameters are identical, ensuring pin-for-pin and mechanical compatibility in existing applications.

Product Status Consideration: The 103976-6 is classified as obsolete, while the 5-103976-6 maintains active product status. This distinction indicates ongoing manufacturer support, availability, and supply chain continuity for the 5-103976-6.

Compliance Advantage: The 5-103976-6 achieves RoHS compliance, whereas the 103976-6 is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the 5-103976-6 is the appropriate selection.

Packaging Difference: The 5-103976-6 is supplied in tube packaging, which may differ from the original packaging specification of the 103976-6. Packaging format does not affect electrical or mechanical performance and is a logistics consideration only.

For new designs, maintenance activities, and applications requiring regulatory compliance, the 5-103976-6 is the recommended selection. For legacy system support requiring exact original part matching, the 103976-6 remains available while inventory exists.

Frequently Asked Questions (FAQ)

Q: Can the 5-103976-6 be used as a direct replacement for the 103976-6 in existing assemblies?

A: Yes. The 5-103976-6 is electrically and mechanically identical to the 103976-6 across all specified parameters. No circuit redesign, PCB modification, or mechanical rework is required for substitution.

Q: What is the significance of the product status difference between these parts?

A: The 103976-6 is obsolete, indicating discontinued manufacturing and limited future availability. The 5-103976-6 is active, meaning it is currently manufactured and supported by TE Connectivity. For ongoing procurement and new applications, the active part number ensures supply chain reliability.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. The difference reflects manufacturing process and material composition changes. If your application or customer requirements mandate RoHS compliance, the 5-103976-6 satisfies this requirement while the 103976-6 does not.

Q: Are there any performance differences between these connectors?

A: No. Both parts maintain identical electrical performance characteristics, contact resistance, current rating capability, and mechanical durability. The 5-103976-6 represents a direct functional equivalent.

Q: Does packaging format affect connector performance or installation?

A: No. Packaging format (tube versus unspecified) is a logistics and storage consideration only. It does not affect connector performance, electrical characteristics, or installation procedures.

Q: What wire gauges are compatible with these connectors?

A: Both connectors accept 22-26 AWG ribbon cable through IDC termination. Wire gauges outside this range are not compatible.

Q: Can these connectors be used with non-ribbon cable?

A: No. These connectors are specifically designed for ribbon cable termination using IDC technology. Other cable types are not compatible with the IDC contact design.

Q: What is the pitch specification and why is it important?

A: The pitch is 0.100" (2.54mm), representing the center-to-center spacing between adjacent contacts. This specification is critical for mating connector compatibility and PCB layout design. Only connectors with identical pitch specifications are mechanically compatible.
