Engineering Selection Recommendations

TE Connectivity 1-103672-1 is the primary specification for applications requiring the original AMPMODU MTE series connector. This part is active and maintains full inventory availability. The connector operates across an extended temperature range of -65°C to 105°C and carries a 3A current rating. However, this part is RoHS non-compliant and REACH-affected, which may restrict use in regulated markets or applications with environmental compliance requirements.

Molex 0705550046 and 0705550081 (SL 70555 series) are functionally equivalent substitutes that provide ROHS3 compliance and REACH unaffected status. Both Molex alternatives maintain the same core connector architecture: 12-position, single-row, right-angle, through-hole header with 0.100" pitch and shrouded 4-wall construction. The operating temperature range for Molex parts is -40°C to 105°C, which covers standard industrial and commercial applications but does not extend to the -65°C minimum of the original part.

Key differences between Molex substitutes include contact finish specifications. Part 0705550046 features 15.0µin (0.38µm) gold plating on mating contacts, while part 0705550081 provides 30.0µin (0.76µm) gold plating. Both use tin finish on posts. The Molex parts employ phosphor bronze contact material with polyester glass-filled insulation, compared to the brass contacts and thermoplastic insulation of the original TE Connectivity part.

Selection between the TE Connectivity original and Molex substitutes depends on compliance requirements, temperature range specifications, and contact finish performance criteria. Applications requiring RoHS3 compliance or REACH unaffected status must use Molex alternatives. Applications requiring operation below -40°C must use the original TE Connectivity part.

Frequently Asked Questions (FAQ)

Q: Can Molex 0705550046 or 0705550081 directly replace TE Connectivity 1-103672-1 in all applications?

A: Direct replacement is possible for applications where the operating temperature range of -40°C to 105°C is acceptable. The Molex parts do not support the extended low-temperature operation (-65°C) of the original TE Connectivity connector. All other core electrical and mechanical parameters align for functional equivalence.

Q: What is the primary difference between Molex 0705550046 and 0705550081?

A: Both parts are identical except for contact finish thickness on mating surfaces. Part 0705550046 provides 15.0µin (0.38µm) gold plating, while part 0705550081 provides 30.0µin (0.76µm) gold plating. Selection depends on contact wear resistance and corrosion protection requirements for the specific application.

Q: Why does the TE Connectivity 1-103672-1 have a lower current rating (3A) compared to the Molex substitutes (no specified rating)?

A: The current rating is a specified parameter for the TE Connectivity part. The Molex parts do not include a current rating specification in the provided data. Current-carrying capacity depends on contact material, cross-sectional area, and thermal design. Consult manufacturer datasheets for detailed current handling specifications when current rating is a critical design parameter.

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

A: Yes. The TE Connectivity 1-103672-1 is RoHS non-compliant and REACH-affected. Both Molex substitutes (0705550046 and 0705550081) are ROHS3 compliant and REACH unaffected. Applications subject to RoHS3 or REACH regulations must use the Molex alternatives.

Q: What is the significance of the contact material difference (Brass vs. Phosphor Bronze)?

A: Contact material affects electrical conductivity, mechanical strength, and corrosion resistance. Brass (TE Connectivity) and phosphor bronze (Molex) are both suitable for connector applications. Phosphor bronze provides enhanced spring properties and wear resistance. The choice depends on specific application requirements for contact force retention and durability.

Q: Do the Molex parts fit the same PCB footprint as the TE Connectivity connector?

A: The core pitch (0.100" / 2.54mm), position count (12), and mounting type (through-hole, right-angle) are identical, ensuring PCB footprint compatibility. Minor dimensional variations exist in contact length and insulation height, but these do not affect board-level mounting compatibility for standard applications.

Q: What packaging format is used for all three parts?

A: All three parts (TE Connectivity 1-103672-1, Molex 0705550046, and Molex 0705550081) are supplied in tube packaging, enabling direct substitution in procurement and assembly workflows.
