• Contact Material: Phosphor Bronze
• Contact Finish: Gold

Mechanical Parameters:

• Connector Style: D-Type
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 50
• Number of Rows: 2
• Shell Size, Connector Layout: 0.050 Pitch x 0.100 Row to Row
• Mounting Type: Through Hole
• Termination: Solder
• Shell Material, Finish: Steel, Nickel Plated
• Flange Feature: Housing/Shell (4-40)

Environmental & Compliance Parameters:

• Operating Temperature Range: -55°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Features: Shielded
• Dielectric Material: Thermoplastic
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 5749070-5 meets all of these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5749070-5 is a direct functional equivalent to the 749070-5 across all electrical, mechanical, and environmental specifications. Both parts are manufactured by TE Connectivity AMP Connectors and belong to the AMPLIMITE .050 III series.

Compliance Advantages of Substitute Part 5749070-5:

Functional Interchangeability:

Both parts are functionally interchangeable in all applications where the 749070-5 is specified. The identical electrical ratings, mechanical dimensions, termination method, and environmental operating parameters ensure direct substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 5749070-5 be used as a direct replacement for the 749070-5 in existing designs?

A: Yes. The 5749070-5 is a direct functional equivalent with identical electrical ratings (1A at 30V), mechanical dimensions (50-position, 0.050 pitch x 0.100 row spacing), mounting type (through-hole solder), and environmental specifications (-55°C to 105°C operating range). No circuit redesign or board layout modification is required.

Q: What are the key differences between these two part numbers?

A: The primary differences are regulatory compliance status and inventory availability. The 5749070-5 is RoHS Compliant and REACH Unaffected, while the 749070-5 is not applicable for RoHS and is REACH Affected. The 5749070-5 also has higher stock availability (2516 pieces versus 721 pieces).

Q: Are both parts from the same manufacturer?

A: Yes. Both the 749070-5 and 5749070-5 are manufactured by TE Connectivity AMP Connectors and are part of the AMPLIMITE .050 III series.

Q: What is the significance of the RoHS and REACH compliance differences?

A: RoHS Compliance indicates the part meets the Restriction of Hazardous Substances directive, restricting the use of specific hazardous materials. REACH Unaffected status indicates the part is not subject to European Union chemical registration requirements. These differences are relevant for applications with regulatory requirements in the European Union or for customers with specific compliance mandates.

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

A: Both parts meet identical electrical and mechanical specifications and carry the same UL94 V-0 flammability rating and operating temperature range. The choice between them should be based on specific regulatory compliance requirements and inventory availability rather than functional performance differences.

Q: What is the packaging format for both parts?

A: Both the 749070-5 and 5749070-5 are supplied in tube packaging, which is standard for D-type connectors in this series.

Q: Are there any differences in contact material or finish between these parts?

A: No. Both parts feature phosphor bronze contacts with gold plating, ensuring identical electrical performance and contact reliability.

Q: What mounting method is used for these connectors?

A: Both connectors use through-hole solder termination with a 4-40 housing/shell flange feature for mechanical mounting and alignment on printed circuit boards.
