Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66598-1 is determined by the following critical parameters:

Core Compatibility Parameters:

• Series designation (Multimate III+)
• Contact type (Socket)
• Termination method (Crimp)
• Wire gauge range (14-18 AWG)
• Contact material (Brass)
• Contact finish thickness (50.0µin / 1.27µm)
• Moisture sensitivity level (MSL 1)

Acceptable Variation Parameters:

• Contact finish composition (Tin-Lead or Tin)
• Packaging format (Cut Tape or Bulk)
• Stamped type designation
• RoHS compliance status
• Inventory availability

Parts 66598-9 and 66601-1 meet all core compatibility parameters. The 66598-9 differs in contact finish (Tin instead of Tin-Lead) and RoHS compliance status. The 66601-1 differs in packaging format (Bulk instead of Cut Tape) while maintaining identical contact specifications.

Parameter Comparison

Engineering Selection Recommendations

66598-1 (Original Part): Select this part when cut tape packaging is required and RoHS non-compliance is acceptable for the application. This part is active and maintains tin-lead contact finish specifications.

66598-9 (Direct Substitute): Select this part when ROHS3 compliance is required and tin contact finish is acceptable in place of tin-lead. This part maintains cut tape packaging and identical wire gauge and termination specifications. Higher inventory availability (5200 pcs) supports procurement timelines.

66601-1 (Similar Substitute): Select this part when bulk packaging is required and tin-lead contact finish specifications must be maintained. This part provides the highest inventory availability (21388 pcs) and is suitable for high-volume applications. RoHS status is not applicable for this packaging format.

All three parts are active products within the Multimate III+ series and maintain functional compatibility for 14-18 AWG crimp socket contact applications.

Frequently Asked Questions (FAQ)

Q: Can 66598-9 be used as a direct replacement for 66598-1?

A: Yes. Both parts are socket contacts in the Multimate III+ series with identical wire gauge (14-18 AWG), termination method (crimp), contact material (brass), and finish thickness (50.0µin). The primary difference is contact finish composition: 66598-9 uses tin finish while 66598-1 uses tin-lead finish. Additionally, 66598-9 is ROHS3 compliant while 66598-1 is RoHS non-compliant.

Q: What is the difference between 66598-1 and 66601-1?

A: Both parts are stamped socket contacts with tin-lead finish in the Multimate III+ series and support 14-18 AWG wire gauges. The primary difference is packaging format: 66598-1 is supplied in cut tape (CT) packaging, while 66601-1 is supplied in bulk packaging. Contact specifications and electrical performance are identical.

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

A: Yes. All three parts are designated for the Multimate III+ series and function as socket contacts with crimp termination for 14-18 AWG wire gauges.

Q: Does contact finish affect electrical performance?

A: Contact finish composition (tin versus tin-lead) and finish thickness are specified parameters. Both 66598-1 (tin-lead) and 66598-9 (tin) maintain the same finish thickness of 50.0µin (1.27µm).

Q: Which part should be selected for high-volume production?

A: Part 66601-1 offers the highest inventory availability (21388 pcs) in bulk packaging format, suitable for high-volume assembly operations requiring socket contacts with tin-lead finish and 14-18 AWG wire gauge specifications.

Q: Are there compliance differences between the substitute parts?

A: Yes. Part 66598-9 is ROHS3 compliant, while 66598-1 is RoHS non-compliant. Part 66601-1 has RoHS status listed as not applicable. REACH status is affected for 66598-1 and 66601-1, while 66598-9 shows vendor undefined status. All parts carry EAR99 ECCN classification.
