Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1605744 is determined by the following critical parameters:

• Contact Size: Must remain 3.6mm to ensure mechanical compatibility with existing connector housings
• Contact Type: Must be pin configuration for proper mating with socket contacts
• Contact Material & Finish: Copper Zinc Alloy with gold finish ensures equivalent electrical performance and corrosion resistance
• Contact Termination: Crimp termination method must be maintained for assembly compatibility
• Series Compatibility: SF series parts maintain design consistency
• RoHS Compliance: All substitutes must meet RoHS requirements for regulatory compliance

Wire gauge range variations are permissible within the constraints of the 3.6mm contact size, as the contact geometry accommodates multiple wire gauges through crimp design parameters. Substitute parts may have narrower or overlapping wire gauge ranges provided they support the application's specific wire gauge requirements.

Engineering Selection Recommendations

1605745 (10-12 AWG Variant)

Part 1605745 is suitable for applications requiring wire gauges in the 10-12 AWG range (4.0 ~ 6.0mm²). This substitute maintains all critical mechanical and electrical parameters: identical 3.6mm contact size, SF series compatibility, crimp termination, and gold-finished copper zinc alloy construction. The part holds active product status with RoHS compliance and unlimited MSL rating, ensuring long-term availability and regulatory alignment.

1607057 (14-18 AWG Variant)

Part 1607057 addresses applications within the 14-18 AWG range (1.0 ~ 2.5mm²). This substitute provides complete mechanical compatibility with the main part while supporting a narrower wire gauge specification. The part is active, RoHS compliant, and carries unlimited MSL rating, providing supply chain stability and regulatory compliance.

Selection Criteria

Choose 1605745 when your application requires accommodation of larger wire gauges (10-12 AWG). Select 1607057 when your application operates within the 14-18 AWG range. Both substitutes are active products with equivalent compliance certifications, making either suitable for new designs or legacy system replacements where the obsolete 1605744 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can I use 1605745 or 1607057 as direct replacements for 1605744?

A: Yes, provided your application's wire gauge requirements fall within the substitute part's specified range. The 1605744 supports 12-18 AWG; 1605745 supports 10-12 AWG; 1607057 supports 14-18 AWG. Select the substitute whose wire gauge range encompasses your application's requirements.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: No. All three parts share identical contact size (3.6mm), contact type (pin), termination method (crimp), and series designation (SF). They are mechanically interchangeable within the SF connector system.

Q: What is the significance of the wire gauge range differences?

A: Wire gauge range indicates the acceptable conductor sizes for crimp termination. The contact geometry remains constant at 3.6mm, but the crimp die and termination parameters vary to accommodate different wire gauges. Select a substitute whose range includes your specific wire gauge.

Q: Why is 1605744 obsolete while 1605745 and 1607057 are active?

A: The 12-18 AWG range of 1605744 may have been consolidated into the two active variants (10-12 AWG and 14-18 AWG) to optimize inventory and manufacturing efficiency. Both active substitutes together cover the original range.

Q: Are all three parts RoHS compliant?

A: Yes. The main part 1605744 and both substitutes 1605745 and 1607057 are RoHS compliant with unlimited MSL rating (1), ensuring regulatory compliance and stable storage conditions.

Q: What packaging is available for these parts?

A: The main part 1605744 is available in unspecified packaging. Substitutes 1605745 and 1607057 are supplied in bulk packaging, suitable for high-volume assembly operations.
