Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 176139-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• 98-position contact count
• Special 18/31 dual combo card type configuration
• 0.100" (2.54mm) pitch spacing
• Phosphor bronze contact material with gold finish (30.0µin thickness)
• Operating temperature range of -55°C to 85°C

Mechanical Compatibility Requirements:

• Female gender
• 2-row configuration
• Card thickness accommodation of 0.054" to 0.070" (1.37mm to 1.78mm)
• Through-hole mounting type
• Polyester glass-filled insulation body
• Black color

Allowable Variations:

• Termination method (press-fit or solder)
• Packaging format (individual or bulk)
• RoHS and REACH compliance status
• Inventory availability

The substitute part 5176139-3 maintains full electrical and mechanical compatibility with the main part 176139-3 while differing in termination technology and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

Selection Criteria Based on Termination Method:

The primary distinction between the main part 176139-3 and substitute part 5176139-3 is the termination technology. The 176139-3 utilizes press-fit termination, which provides mechanical insertion without solder reflow. The 5176139-3 employs solder termination, requiring thermal processing during assembly. Selection between these two parts depends on the assembly process capability and PCB design specifications of the target application.

Selection Criteria Based on Regulatory Compliance:

The 176139-3 is RoHS non-compliant and REACH Affected, suitable for applications without regulatory restrictions or legacy system requirements. The 5176139-3 is ROHS3 Compliant and REACH Unaffected, required for applications subject to European Union environmental directives or customer-mandated compliance standards.

Selection Criteria Based on Packaging and Availability:

The 176139-3 is supplied in standard packaging with 914 pieces currently in inventory. The 5176139-3 is supplied in bulk packaging with 1577 pieces currently in inventory. Packaging selection depends on procurement volume requirements and supply chain logistics.

Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, card type configuration, contact materials, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 5176139-3 be used as a direct replacement for the 176139-3 in existing designs?

A: The 5176139-3 is electrically and mechanically compatible with the 176139-3 across all critical parameters. However, the termination method differs (solder versus press-fit). Direct replacement requires verification that the PCB assembly process supports solder termination and that the design does not mandate press-fit insertion technology.

Q: What is the primary difference between these two connector variants?

A: The main difference is the termination method. The 176139-3 uses press-fit termination for mechanical insertion into plated through-holes. The 5176139-3 uses solder termination, requiring reflow soldering during PCB assembly. Both connectors have identical electrical performance and mechanical dimensions.

Q: Are there any compliance differences between the two parts?

A: Yes. The 176139-3 is RoHS non-compliant and REACH Affected. The 5176139-3 is ROHS3 Compliant and REACH Unaffected. Applications subject to European Union environmental regulations or customer compliance requirements must use the 5176139-3.

Q: Do both connectors support the same card thickness range?

A: Yes. Both the 176139-3 and 5176139-3 accommodate card thickness from 0.054" to 0.070" (1.37mm to 1.78mm). The special 18/31 dual combo configuration and dual read-out design are identical across both parts.

Q: What is the pitch spacing for these connectors?

A: Both connectors feature 0.100" (2.54mm) pitch spacing with 98 total positions arranged in a 2-row configuration. The special 18/31 dual combo card type maintains this spacing across all contact positions.

Q: Can these connectors be used in high-temperature applications?

A: Both the 176139-3 and 5176139-3 operate across the temperature range of -55°C to 85°C. Applications requiring operation outside this range require alternative connector designs.

Q: What contact material and finish are used in these connectors?

A: Both connectors use phosphor bronze contacts with gold plating. The gold contact finish thickness is 30.0µin (0.76µm) on both parts, providing consistent electrical performance and corrosion resistance.

Q: Is there a difference in inventory availability between these two parts?

A: The 176139-3 has 914 pieces in stock, while the 5176139-3 has 1577 pieces in stock. The 5176139-3 is supplied in bulk packaging, which may affect procurement and handling procedures.
