Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 66564-6 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Series: Multimate III+
• Type: Stamped
• Pin or Socket: Pin
• Contact Termination: Crimp
• Wire Gauge: 20-24 AWG
• Contact Material: Brass
• Contact Finish Thickness: 50.0µin (1.27µm)
• Packaging: Cut Tape (CT)

Allowable Variation:

• Contact Finish: The primary part features tin-lead plating, while substitute parts may feature tin plating. Both finishes are compatible within the Multimate III+ series architecture and maintain equivalent electrical and mechanical performance at the specified finish thickness.

The substitute part 1-66564-2 satisfies all mandatory matching parameters and differs only in contact finish composition, which represents an allowable substitution within this product category.

Parameter Comparison

Engineering Selection Recommendations

Part 66564-6 (Tin-Lead Finish): This part is suitable for applications where RoHS compliance is not required or where legacy system compatibility with tin-lead plating is specified. The part is currently in active production status with substantial inventory availability (2,818 pieces). RoHS status is non-compliant, and REACH status is vendor undefined.

Part 1-66564-2 (Tin Finish): This part is suitable for applications requiring RoHS compliance and REACH compliance documentation. The substitute part is also in active production status with higher inventory availability (5,404 pieces). The tin finish at equivalent thickness (50.0µin) provides electrical and mechanical performance parity with the tin-lead variant within the Multimate III+ series.

Selection between these parts should be based on regulatory compliance requirements applicable to the end application. Both parts maintain identical mechanical fit, electrical performance, and crimp termination characteristics within the Multimate III+ connector architecture.

Frequently Asked Questions (FAQ)

Q: Can part 1-66564-2 be used as a direct replacement for 66564-6 in existing designs?

A: Yes. Both parts are stamped pin contacts in the Multimate III+ series with identical wire gauge ratings (20-24 AWG), crimp termination specifications, contact material (brass), and finish thickness (50.0µin). The difference in finish composition (tin versus tin-lead) does not affect mechanical fit or electrical performance within this connector series.

Q: What is the primary difference between these two parts?

A: The primary difference is the contact finish composition. Part 66564-6 features tin-lead plating, while part 1-66564-2 features tin plating. Both are applied at the same thickness (50.0µin / 1.27µm). Additionally, part 1-66564-2 is RoHS compliant and REACH unaffected, while part 66564-6 is RoHS non-compliant with vendor-undefined REACH status.

Q: Are there any packaging differences between these parts?

A: No. Both parts are supplied in Cut Tape (CT) packaging format.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, select part 1-66564-2. For applications without RoHS compliance requirements, either part is functionally equivalent.

Q: Do these parts have different moisture sensitivity levels?

A: No. Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts currently in active production?

A: Yes. Both parts maintain active product status with TE Connectivity AMP Connectors. Part 1-66564-2 has higher current inventory availability (5,404 pieces) compared to part 66564-6 (2,818 pieces).
