Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 34123-2 is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Criteria:

• Terminal type classification (Circular)
• Stud size designation (#10 Stud)
• Wire gauge range (14-16 AWG)
• Termination method (Crimp)
• Contact material (Copper)
• Insulation configuration (Non-Insulated)
• Mounting orientation (Free Hanging/In-Line)

Physical Dimensional Equivalence:

• Overall length: 0.636" (16.15mm)
• Outer edge width: 0.343" (8.71mm)
• Thickness: 0.031" (0.79mm)

Construction Features:

• Brazed seam construction
• Serrated termination design

Parts meeting all these parameters are classified as direct substitutes. The 34123-2 belongs to the Solistrand series, and substitute parts maintain this series designation and base product number (34123) while differing in specific variant coding or contact finish specifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 8-34123-1 is a direct functional substitute for the 34123-2 across all critical electrical and mechanical parameters. Both components share identical terminal type, stud size, wire gauge range, termination method, contact material, and physical dimensions.

Product Status Consideration: The 34123-2 is discontinued at DiGi Electronics, while the 8-34123-1 maintains active product status with significantly higher inventory availability (3352 pieces versus 959 pieces). For new designs or ongoing production requirements, the 8-34123-1 provides assured supply continuity.

Compliance Differences: The 34123-2 carries explicit RoHS Compliant certification. The 8-34123-1 lists RoHS Status as "Not applicable," indicating a potential difference in regulatory classification or documentation. Applications subject to RoHS requirements should verify compliance documentation with the manufacturer before substitution.

Contact Finish Specification: The 8-34123-1 specifies a tin contact finish, while the 34123-2 contact finish is not specified in available documentation. Tin plating provides enhanced corrosion resistance and solderability characteristics. This difference does not affect mechanical compatibility but may influence performance in specific environmental or assembly conditions.

Selection Basis: Choose the 8-34123-1 for new applications, production restocking, or when active product status and higher inventory availability are required. Retain the 34123-2 only when existing design documentation explicitly specifies the original part number and RoHS compliance certification is a mandatory requirement.

Frequently Asked Questions (FAQ)

Q: Are the 34123-2 and 8-34123-1 mechanically interchangeable?

A: Yes. Both components share identical terminal type (circular), stud size (#10), wire gauge range (14-16 AWG), overall length (0.636"), outer edge width (0.343"), and thickness (0.031"). Physical interchangeability is confirmed across all dimensional parameters.

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

A: Functionally, both components perform identical operations as ring terminal connectors with crimp termination. The primary difference is the contact finish: the 8-34123-1 specifies tin plating, while the 34123-2 finish is not specified. Tin plating enhances corrosion resistance and solderability.

Q: Why is the 34123-2 discontinued?

A: The 34123-2 is discontinued at DiGi Electronics. The 8-34123-1 remains in active production with higher inventory levels, indicating manufacturer preference for the updated variant.

Q: Does the tin finish on the 8-34123-1 affect wire gauge compatibility?

A: No. The tin finish is applied to the copper contact material and does not alter the wire gauge range (14-16 AWG) or crimp termination specifications. Wire gauge compatibility remains identical.

Q: Can I use the 8-34123-1 in applications originally designed for the 34123-2?

A: Yes, for applications where RoHS compliance is not explicitly mandated. The 8-34123-1 provides identical electrical and mechanical performance. If your application requires RoHS Compliant certification, verify the 8-34123-1 compliance status with TE Connectivity before substitution.

Q: What is the difference in inventory availability?

A: The 34123-2 has 959 pieces in stock, while the 8-34123-1 has 3352 pieces available. The 8-34123-1 offers significantly higher inventory availability for production requirements.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 34123-2 and 8-34123-1 are manufactured by TE Connectivity AMP Connectors and belong to the Solistrand series.

Q: What does "Brazed Seam, Serrated Termination" mean?

A: Brazed seam refers to the construction method where the terminal ring is joined using brazing, providing structural integrity. Serrated termination describes the textured surface on the crimp end that grips the wire insulation and conductor, ensuring secure attachment during the crimping process.

Q: Can these terminals be used with insulated wire?

A: No. Both the 34123-2 and 8-34123-1 are classified as non-insulated terminals. They are designed for bare copper wire or wire with external insulation that does not extend into the terminal crimp area.
