Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 749210-5 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector style (D-Type)
• Connector type (Receptacle, Female Sockets)
• Number of positions (50)
• 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 finish (Gold)
• Contact material (Phosphor Bronze)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging, In-Line)
• Termination method (IDC, Ribbon Cable)
• Shielded feature
• Operating temperature range (-55°C to 105°C)
• Material flammability rating (UL94 V-0)

Regulatory and Compliance Parameters:

• Series designation (AMPLIMITE .050 III)
• Moisture Sensitivity Level (MSL 1)

The substitute part 5749210-5 maintains full equivalence across all critical electrical and mechanical parameters. The primary differences are shell finish material (tin plated versus nickel plated) and product status (active versus obsolete), with the substitute offering improved regulatory compliance through RoHS3 certification.

Parameter Comparison

Engineering Selection Recommendations

The 5749210-5 connector serves as the direct active equivalent to the obsolete 749210-5 part number. Both connectors are manufactured by TE Connectivity AMP Connectors within the AMPLIMITE .050 III series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 749210-5 is classified as obsolete, while the 5749210-5 is active. For new designs and ongoing production requirements, the 5749210-5 is the appropriate selection to ensure long-term supply chain availability.

Regulatory Compliance: The 5749210-5 achieves RoHS3 compliance, whereas the 749210-5 is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must utilize the 5749210-5 substitute.

Shell Finish Difference: The 749210-5 features nickel-plated steel shell, while the 5749210-5 features tin-plated steel shell. Both finishes provide corrosion protection and electromagnetic shielding. The tin-plated finish of the substitute part is compatible with standard connector mating applications and does not affect electrical performance or mechanical fit.

Inventory and Availability: The 5749210-5 is available in bulk packaging with 1009 pieces in stock, providing superior availability compared to the obsolete 749210-5 designation.

Frequently Asked Questions (FAQ)

Q: Can the 5749210-5 directly replace the 749210-5 in existing applications?

A: Yes. The 5749210-5 maintains full electrical and mechanical equivalence to the 749210-5 across all critical parameters including connector style, position count, pitch, termination method, current and voltage ratings, operating temperature range, and shielding characteristics. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the difference between the nickel-plated and tin-plated shell finishes?

A: Both finishes provide corrosion protection and electromagnetic shielding. Nickel plating offers superior corrosion resistance in harsh environments, while tin plating provides excellent solderability and is standard in modern connector manufacturing. For standard indoor applications and ribbon cable termination, both finishes perform equivalently.

Q: Does the RoHS3 compliance of the 5749210-5 affect compatibility with the 749210-5?

A: No. RoHS3 compliance is a regulatory and environmental designation that does not alter electrical or mechanical performance. The 5749210-5 is fully compatible with applications designed for the 749210-5. RoHS3 compliance is an advantage for applications subject to RoHS directives or customer environmental requirements.

Q: Are there packaging differences between the two part numbers?

A: The 749210-5 packaging designation is not specified in available data. The 5749210-5 is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging differences do not affect connector performance or interchangeability.

Q: What is the contact finish thickness specification for the 5749210-5?

A: The contact finish thickness for the 5749210-5 is not specified in available technical data. Both parts feature gold contact finish on phosphor bronze contact material. The 749210-5 specifies 30.0µin (0.76µm) contact finish thickness. For applications with specific contact finish thickness requirements, direct verification with TE Connectivity is recommended.

Q: Can the 5749210-5 be used in applications requiring the exact nickel-plated finish of the 749210-5?

A: The 5749210-5 features tin-plated shell finish rather than nickel-plated finish. For applications with explicit nickel-plated shell requirements, the finish difference must be evaluated against specific environmental or performance criteria. In standard ribbon cable connector applications, tin-plated finish is functionally equivalent.
