Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 749085-9 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug, Male Pins)
• Number of positions (100)
• Number of rows (2)
• Shell size and connector layout (0.050 Pitch x 0.100 Row to Row)
• Current rating (1A)
• Voltage rating (30V)
• Contact material (Phosphor Bronze)
• Contact finish (Gold)

Mechanical Compatibility Parameters:

• Connector style (D-Type)
• Mounting type (Through Hole)
• Termination method (Solder)
• Flange feature (Housing/Shell 4-40)
• Dielectric material (Liquid Crystal Polymer, Polyester)

Environmental & Regulatory Parameters:

• Operating temperature range (-55°C ~ 105°C)
• Material flammability rating (UL94 V-0)
• Shielded feature

The substitute part 5749085-9 maintains full equivalence across all critical parameters, with the primary distinction being series designation (AMPLIMITE .050 III versus AMPLIMITE .050) and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5749085-9 serves as a direct functional equivalent to the 749085-9 across all electrical and mechanical parameters. Both connectors are classified as obsolete products within the AMPLIMITE .050 series family.

The primary distinction between these parts is regulatory compliance status. The 749085-9 is RoHS non-compliant, while the 5749085-9 achieves ROHS3 compliance. For applications subject to RoHS3 regulatory requirements or environmental compliance mandates, the 5749085-9 is the appropriate selection. For legacy systems where RoHS compliance is not a requirement, either part maintains functional equivalence.

Both connectors share identical electrical ratings (1A current, 30V voltage), mechanical specifications (100 positions, 2 rows, 0.050 pitch), and environmental operating parameters (-55°C to 105°C). The shell material finish specification is not provided for the 5749085-9; however, this does not affect functional compatibility given the equivalence of all other material and contact specifications.

Frequently Asked Questions (FAQ)

Q: Are the 749085-9 and 5749085-9 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: D-Type plug configuration, 100 positions across 2 rows, 0.050 pitch with 0.100 row-to-row spacing, through-hole solder termination, and 4-40 housing/shell flange feature. Physical mounting and board-level integration are identical.

Q: Are the 749085-9 and 5749085-9 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications: 1A current rating, 30V voltage rating, phosphor bronze contacts with gold finish, and shielded configuration. Signal integrity and electrical performance are equivalent.

Q: What is the difference between AMPLIMITE .050 and AMPLIMITE .050 III series?

A: The series designation indicates design iteration within the AMPLIMITE .050 connector family. Both series maintain the same 0.050 pitch and 0.100 row-to-row spacing specifications. The primary documented difference is the RoHS compliance status of the 5749085-9 (ROHS3 Compliant) versus the 749085-9 (RoHS non-compliant).

Q: Can I use the 5749085-9 as a replacement for the 749085-9 in existing equipment?

A: Yes, provided that regulatory compliance requirements do not prohibit the use of RoHS non-compliant components in your application. The 5749085-9 is functionally equivalent and maintains all electrical and mechanical specifications. If your application or region mandates RoHS3 compliance, the 5749085-9 is the appropriate selection.

Q: Are there any environmental or temperature limitations I should consider?

A: Both connectors operate across the identical temperature range of -55°C to 105°C and carry UL94 V-0 material flammability rating. Environmental operating parameters are equivalent.

Q: What termination method is used for these connectors?

A: Both the 749085-9 and 5749085-9 utilize solder termination for through-hole mounting. No alternative termination methods are available for these part numbers.

Q: Are these connectors suitable for high-frequency applications?

A: The provided specifications do not include frequency response or impedance characteristics. Selection for high-frequency applications requires additional technical documentation beyond the parameters specified for these connectors.
