• Connector type: Receptacle
• Number of positions: 10
• Pitch - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Contact finish - mating: Gold (10.0µin thickness)
• Contact finish - post: Tin
• Current rating: 4.7A per contact
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant
• Insulation material: Liquid Crystal Polymer (LCP)
• Contact material: Phosphor Bronze
• Contact shape: Square

Both parts belong to the SSW series and share the same base product number (SSW-110), confirming functional equivalence.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory and safety requirements are met regardless of which part is selected. No performance or compatibility differences exist between these connectors.

Frequently Asked Questions (FAQ)

Q: Can SSW-110-01-L-S be used as a direct replacement for SSW-110-21-L-S?

A: Yes. Both parts are functionally identical 10-position receptacle connectors with 0.100" pitch, gold-plated mating contacts, tin-plated posts, and 4.7A per contact current rating. They share the same operating temperature range, flammability rating, and RoHS compliance status.

Q: Are there any mechanical differences between these connectors?

A: No. Both connectors have identical insulation height (0.335"), contact length (0.104"), contact shape (square), and insulation material (Liquid Crystal Polymer). They are mechanically interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSW-110-21-L-S and SSW-110-01-L-S are ROHS3 compliant and carry UL94 V-0 flammability rating. They are classified under the same ECCN (EAR99) and HTSUS code (8536.69.4040).

Q: What is the difference between these part numbers?

A: The part numbers differ only in their suffix designation (21-L-S versus 01-L-S). This variation does not affect electrical or mechanical performance. Both parts belong to the SSW series with base product number SSW-110.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both connectors are rated for operating temperatures from -55°C to 125°C, making them suitable for industrial and demanding thermal environments.
