Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 6-103673-6 (Primary Substitute)

The 6-103673-6 is the preferred substitute for the obsolete 1-103906-6. Both parts are manufactured by TE Connectivity within the AMPMODU MTE series and share identical core electrical and mechanical specifications. The 6-103673-6 is currently Active in production status, ensuring long-term availability and supply chain continuity.

Key advantages of the 6-103673-6:

• Identical pitch, position count, and mounting configuration
• Matching operating temperature range (-65°C ~ 105°C)
• Same current rating (3A) and flammability rating (UL94 V-0)
• RoHS Compliant status, meeting modern regulatory requirements
• Additional Board Lock feature for enhanced mechanical retention
• Bulk packaging option for production environments

Minor differences include reduced gold plating thickness on mating contacts (15.0µin versus 30.0µin) and Tin post finish instead of Tin-Lead. These differences do not affect functional compatibility in standard applications.

Molex 0705530051 (Alternative Substitute)

The 0705530051 provides cross-manufacturer compatibility for applications requiring connector diversity or supply chain redundancy. This part maintains the critical 17-position, 2.54mm pitch, Through Hole Right Angle configuration.

Considerations for the 0705530051:

• Different manufacturer (Molex) provides supply chain independence
• Operating temperature range of -40°C ~ 105°C is suitable for most applications but does not extend to -65°C
• Contact material is Phosphor Bronze instead of Brass
• Mating contact finish is Tin instead of Gold
• Insulation material is Polyester Glass Filled instead of Thermoplastic
• Specified voltage rating of 250V provides additional electrical specification clarity
• ROHS3 Compliant status meets current regulatory standards
• Tube packaging suitable for smaller production volumes

The 0705530051 is suitable for applications where the -40°C lower temperature limit is acceptable and where cross-manufacturer qualification is permitted.

Frequently Asked Questions (FAQ)

Q: Can the 6-103673-6 be used as a direct replacement for the 1-103906-6 in existing designs?

A: Yes. The 6-103673-6 maintains identical pitch (2.54mm), position count (17), mounting type (Through Hole Right Angle), and electrical ratings (3A, -65°C ~ 105°C). The connector footprint and mating interface are compatible. The primary design consideration is the reduced gold plating thickness on mating contacts, which does not affect standard applications.

Q: What is the significance of the RoHS compliance difference between the main part and substitutes?

A: The 1-103906-6 is RoHS non-compliant, while both substitutes (6-103673-6 and 0705530051) are RoHS Compliant or ROHS3 Compliant. For new designs and products subject to RoHS regulations, the compliant substitutes are required. For legacy system maintenance, RoHS non-compliant parts may be acceptable depending on application and regulatory jurisdiction.

Q: Are there mechanical compatibility concerns with the Molex 0705530051?

A: The 0705530051 has slightly different dimensional specifications: mating contact length of 0.240" (6.10mm) versus 0.230" (5.84mm) on the original part, and insulation height of 0.215" (5.45mm) versus 0.200" (5.08mm). These minor differences may affect board layout spacing and mating depth. Verification of mechanical fit within the specific application is necessary before implementation.

Q: What is the impact of the -40°C lower temperature limit on the Molex part?

A: The Molex 0705530051 operates from -40°C to 105°C, while the original part operates from -65°C to 105°C. Applications requiring operation below -40°C must use the TE Connectivity 6-103673-6 or original 1-103906-6. For applications with minimum operating temperatures above -40°C, the Molex part is suitable.

Q: How do contact material differences affect connector performance?

A: The original part uses Brass contacts with Gold mating finish, while the Molex substitute uses Phosphor Bronze contacts with Tin mating finish. Phosphor Bronze provides higher spring force and durability, while Brass with Gold offers superior corrosion resistance and lower contact resistance. Both materials are suitable for standard 3A applications. Contact material selection depends on specific environmental and electrical requirements.

Q: What packaging options are available for production planning?

A: The 1-103906-6 is supplied in standard packaging (not specified). The 6-103673-6 is available in Bulk packaging, suitable for high-volume production. The 0705530051 is supplied in Tube packaging, appropriate for smaller production runs or component kitting. Packaging selection should align with production volume and inventory management requirements.

Q: Are there any feature differences that affect connector functionality?

A: The 6-103673-6 includes a Board Lock feature in addition to the Keying Slot present on the original part. The Board Lock provides additional mechanical retention during mating and unmating cycles. The Molex 0705530051 does not specify additional features beyond the standard Latch Holder fastening. These feature differences do not affect basic electrical compatibility but may influence mechanical robustness in high-vibration environments.
