Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1688997 is determined by the following critical parameters:

• Contact Type & Form: Female socket, machined construction
• Termination Method: Crimp termination
• Contact Material & Finish: Copper alloy with gold plating
• Wire Gauge Compatibility: 24-28 AWG range
• Connector Category: D-Sub signal contacts
• Compliance Requirements: RoHS compliance and MSL Level 1

The substitute part 1418787 maintains compatibility across these core parameters while operating within the CUC series. Wire gauge specification shifts to 26-28 AWG, representing a narrower range within the original 24-28 AWG specification, which is acceptable for applications requiring 26-28 AWG wire gauges.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain RoHS compliance and MSL Level 1 rating, ensuring suitability for standard industrial and commercial applications. The primary distinction lies in wire gauge specification: the 1688997 accommodates 24-28 AWG, while the 1418787 is specified for 26-28 AWG. Selection between these parts should be based on the actual wire gauge requirements of the application. For applications using 26-28 AWG wire, either part is functionally equivalent. For applications requiring 24-25 AWG wire support, the 1688997 remains the appropriate choice where availability permits.

Frequently Asked Questions (FAQ)

Q: Can the 1418787 substitute for the 1688997 in all applications?

A: Substitution is valid only for applications using 26-28 AWG wire gauges. Applications requiring 24-25 AWG wire support cannot use the 1418787 due to its narrower wire gauge specification.

Q: What is the significance of the wire gauge difference between these parts?

A: Wire gauge determines the physical dimensions of the wire that can be properly crimped into the contact. The 1688997 accepts a broader range (24-28 AWG), while the 1418787 is optimized for the narrower 26-28 AWG range. Using a contact outside its specified wire gauge range may result in improper termination and connection failure.

Q: Are both parts RoHS compliant?

A: Yes, both the 1688997 and 1418787 are RoHS compliant and carry MSL Level 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Q: What does the obsolete status of the 1688997 mean for procurement?

A: Obsolete status indicates the part is no longer in active production by the manufacturer. The 1418787 serves as the current production equivalent for applications within its wire gauge specification range. Existing inventory of the 1688997 remains available but future procurement should transition to the 1418787 where wire gauge requirements permit.

Q: Are the contact materials identical between these parts?

A: Yes, both parts use copper alloy contacts with gold plating, ensuring equivalent electrical performance and corrosion resistance characteristics.
