TE Connectivity AMP Connectors 66587-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 66587-1 is a pin contact designed for the Multimate VI connector series. This stamped brass pin contact with tin finish is rated for 14-18 AWG wire gauges and utilizes crimp termination. The part is currently active in production with ROHS3 compliance and MSL 1 rating, indicating unlimited moisture sensitivity tolerance. Substitute parts are identified when inventory constraints, packaging format requirements, or specific finish specifications necessitate alternative sourcing while maintaining functional compatibility within the Multimate VI series ecosystem.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66587-1 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Contact type: Pin (not socket)
• Termination method: Crimp
• Stamped construction
• Wire gauge compatibility: Minimum 14 AWG support required
• RoHS3 compliance status
• ECCN classification: EAR99

Acceptable Variation Parameters:

• Contact finish material (tin, gold, or equivalent conductive coatings)
• Contact base material (brass or copper alloy)
• Packaging format (bulk, cut tape, or reel)
• Moisture sensitivity level (when rated as not applicable or equivalent)
• Series designation (when mechanically and electrically compatible within connector ecosystem)

The substitute part SM14M-1S6 meets all mandatory criteria while introducing a gold finish specification and copper alloy base material. Wire gauge support is limited to 14 AWG in the substitute, representing a narrower range than the primary part's 14-18 AWG specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (66587-1): Select the TE Connectivity AMP Connectors 66587-1 for applications requiring wire gauge flexibility across the 14-18 AWG range. This part maintains active production status with ROHS3 compliance and unlimited moisture sensitivity tolerance. Tin finish provides standard corrosion resistance suitable for general industrial applications. Bulk packaging accommodates high-volume assembly operations.

Substitute Part Selection (SM14M-1S6): The Souriau-Sunbank by Eaton SM14M-1S6 serves as a functional substitute when 14 AWG wire gauge specification is sufficient for the application. This part is active in production with ROHS3 compliance and offers gold finish with specified thickness (29.5µin/0.75µm), providing enhanced corrosion resistance and contact reliability in demanding environments. Cut tape packaging supports automated pick-and-place assembly workflows. The copper alloy base material with gold finish delivers superior electrical conductivity and contact durability compared to tin-finished brass.

Both parts share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can SM14M-1S6 replace 66587-1 in all applications?

A: SM14M-1S6 is functionally compatible with 66587-1 when the application wire gauge requirement is 14 AWG. If the assembly requires 16 AWG or 18 AWG wire accommodation, SM14M-1S6 is not suitable due to its single-gauge specification. Verify wire gauge requirements before substitution.

Q: What is the difference between tin and gold contact finishes?

A: Tin finish (66587-1) provides standard corrosion resistance and is suitable for general industrial environments. Gold finish (SM14M-1S6) offers superior corrosion resistance, lower contact resistance, and enhanced reliability in high-reliability or harsh environment applications. Gold finish is specified at 29.5µin thickness on the substitute part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 66587-1 and SM14M-1S6 carry ROHS3 compliance certification, confirming restriction of hazardous substances in accordance with applicable regulations.

Q: What packaging formats are available?

A: The primary part 66587-1 is supplied in bulk packaging. The substitute SM14M-1S6 is supplied in cut tape (CT) format. Select packaging based on assembly process requirements: bulk for manual or high-volume bin-fed systems, cut tape for automated pick-and-place equipment.

Q: Do both parts use crimp termination?

A: Yes. Both 66587-1 and SM14M-1S6 utilize crimp termination methodology. Ensure crimp tooling and die specifications match the contact geometry of the selected part.

Q: What is the moisture sensitivity level difference?

A: The primary part 66587-1 carries MSL 1 rating (unlimited moisture sensitivity tolerance), indicating no moisture-related storage or handling restrictions. The substitute SM14M-1S6 lists MSL as not applicable, indicating the part does not require moisture sensitivity classification under standard testing protocols.

Q: Are these parts mechanically compatible with Multimate VI connectors?

A: The primary part 66587-1 is specified for the Multimate VI series. The substitute SM14M-1S6 belongs to the Trim Trio® SM/SC-M series. Mechanical compatibility between series must be verified through connector housing specifications before substitution.
