Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 106739-4 are identified based on strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Number of Positions: 128
• Pitch: 0.100" (2.54mm)
• Number of Rows: 4
• Style: C
• Contact Finish: Gold
• Termination: Solder

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole, Right Angle
• Connector Category: Backplane Connectors (DIN)

Environmental & Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating Temperature Range: Minimum -55°C capability

The substitute parts listed below maintain these core parameters, enabling direct functional replacement in PCB applications. Differences in connector type designation (Plug vs. Header), operating temperature upper limits, current ratings, and material specifications do not preclude substitution where mechanical and electrical pin configurations remain identical.

Engineering Selection Recommendations

Primary Substitute: KYOCERA AVX 108457128002025

The KYOCERA AVX 108457128002025 serves as the primary substitute for the obsolete TE Connectivity 106739-4. Both connectors share identical electrical and mechanical specifications across all critical parameters: 128 positions, 0.100" pitch, 4-row configuration, Style C, through-hole right-angle mounting, and solder termination with gold contact finish. Both maintain ROHS3 compliance and MSL Level 1 rating. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. The extended operating temperature range (-65°C vs. -55°C minimum) and inclusion of current rating specification (3A) provide enhanced environmental performance margins.

Secondary Substitute: KYOCERA AVX 168457128002025

The KYOCERA AVX 168457128002025 provides an alternative substitute with identical electrical and mechanical compatibility to the primary option. This variant includes a Board Lock feature, which provides mechanical retention enhancement for applications requiring additional connector stability. All other specifications remain equivalent to the primary substitute, including active product status, ROHS3 compliance, and environmental ratings.

Selection Basis:

Both KYOCERA AVX alternatives are recommended based on product status transition from obsolete to active manufacturing, maintained compliance certifications (ROHS3, EAR99), and complete parameter alignment with the original TE Connectivity part. The choice between the two KYOCERA AVX options depends on whether the Board Lock feature is required for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the KYOCERA AVX 108457128002025 or 168457128002025 directly replace the TE Connectivity 106739-4 in existing designs?

A: Yes. Both KYOCERA AVX parts maintain identical pin count (128 positions), pitch spacing (0.100"), row configuration (4 rows), mounting orientation (right-angle through-hole), and termination method (solder). The gold contact finish and electrical class specifications are equivalent, enabling direct PCB footprint compatibility.

Q: What is the difference between the two KYOCERA AVX substitute parts?

A: The primary difference is the inclusion of a Board Lock feature in part number 168457128002025. This feature provides mechanical retention of the connector to the PCB. All other electrical and mechanical specifications are identical between the two parts.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: No. All three parts maintain ROHS3 compliance, EAR99 export classification, and identical HTSUS codes. Moisture sensitivity levels are equivalent at MSL Level 1 (Unlimited).

Q: Does the extended operating temperature range of the substitute parts affect compatibility?

A: No. The substitute parts operate from -65°C to 125°C, compared to the original part's -55°C to 125°C range. This represents an expanded capability that maintains full compatibility with the original specification range.

Q: What is the significance of the glass-filled polyester thermoplastic insulation in the substitute parts?

A: The glass-filled variant provides enhanced mechanical strength and thermal stability compared to unfilled polyester thermoplastic. This material upgrade does not affect electrical compatibility or PCB mounting characteristics.

Q: Are the substitute parts currently available?

A: Yes. Both KYOCERA AVX parts are classified as active products with confirmed inventory availability (861 and 710 units respectively), ensuring supply continuity for replacement and new design applications.

Q: Does the 3A current rating specification on the substitute parts indicate a difference in electrical capability?

A: The current rating specification on the substitute parts provides explicit electrical performance documentation. The original part does not include a stated current rating in the provided specifications. Both parts are suitable for backplane connector applications within their respective electrical specifications.
