Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66566-2 contact is determined by the following core parameters that must remain constant across all equivalent parts:

Critical 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)
• Moisture Sensitivity Level: 1 (Unlimited)

Parameters Allowed to Vary:

• Packaging format (Bulk to Cut Tape)
• Contact Finish specification (Tin-Lead to Tin)
• RoHS compliance status
• REACH compliance status

The identified substitutes maintain full electrical and mechanical compatibility with the 66566-2 while offering alternatives in packaging configuration and finish specification. Selection between substitutes depends on application requirements for RoHS compliance, REACH regulatory status, and packaging quantity needs.

Parameter Comparison

Engineering Selection Recommendations

66566-2 (Tin-Lead Finish, Bulk Packaging): Use this part for applications where tin-lead plating is specified and bulk packaging is acceptable. This part is RoHS non-compliant and REACH Affected, making it suitable for legacy systems or applications without regulatory restrictions on lead content.

66564-6 (Tin-Lead Finish, Cut Tape Packaging): Select this substitute when tin-lead finish is required but cut tape packaging is preferred for automated assembly or smaller quantity requirements. This part maintains the same tin-lead finish as the main part and is RoHS non-compliant. REACH status is Vendor Undefined. Cut tape packaging provides an alternative to bulk format while preserving electrical and mechanical specifications.

66566-7 (Tin Finish, Bulk Packaging, RoHS Compliant): Use this substitute for applications requiring RoHS compliance and REACH Unaffected status. The contact finish differs from the main part, featuring tin plating instead of tin-lead. This part is suitable for new designs or applications with regulatory requirements prohibiting lead content. Bulk packaging matches the main part format.

Selection between substitutes depends on regulatory compliance requirements, packaging format needs, and finish specification constraints for the target application.

Frequently Asked Questions (FAQ)

Q: Can 66564-6 be used as a direct replacement for 66566-2?

A: Yes, 66564-6 is electrically and mechanically equivalent to 66566-2. Both contacts feature tin-lead plating, 20-24 AWG wire gauge capability, and identical contact finish thickness. The primary difference is packaging format: 66564-6 is supplied in cut tape while 66566-2 is supplied in bulk. Selection depends on assembly process requirements and quantity needs.

Q: What is the difference between 66566-2 and 66566-7?

A: Both parts share the same base product number and bulk packaging format. The key difference is contact finish: 66566-2 features tin-lead plating while 66566-7 features tin plating only. Additionally, 66566-7 is RoHS Compliant and REACH Unaffected, whereas 66566-2 is RoHS non-compliant and REACH Affected. Select 66566-7 for applications requiring lead-free compliance.

Q: Are all three parts compatible with Multimate III+ connectors?

A: Yes. All three parts are stamped pin contacts for the Multimate III+ series with identical wire gauge ratings (20-24 AWG), contact material (brass), and contact finish thickness (50.0µin). They are mechanically and electrically interchangeable within the connector system.

Q: Which substitute should I use if RoHS compliance is required?

A: Use 66566-7. This part is RoHS Compliant and REACH Unaffected. It features tin plating instead of tin-lead and is available in bulk packaging. All other electrical and mechanical parameters remain compatible with the original specification.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (bulk versus cut tape) does not affect electrical or mechanical performance. The choice between 66566-2 (bulk) and 66564-6 (cut tape) depends on assembly process requirements, inventory management, and handling preferences.

Q: What does "Moisture Sensitivity Level 1 (Unlimited)" mean?

A: MSL 1 indicates the contact has unlimited shelf life and requires no special moisture control during storage or handling. All three substitute parts share this specification.

Q: Can I mix 66566-2 and 66566-7 in the same connector assembly?

A: Yes. Both parts are mechanically and electrically compatible within the Multimate III+ series. However, mixing different finish specifications (tin-lead and tin) in a single assembly may create inconsistent contact characteristics. Design and application requirements should determine whether mixed finishes are acceptable.
