Key Parameters

Substitute Part Grouping Explanation

The SSW-122-01-G-D qualifies as a direct substitute for the SSW-122-01-L-D based on the following critical parameters that define interchangeability within the SSW series:

Matching Parameters:

• Connector type: Receptacle
• Position count: 44 positions
• Pitch specification: 0.100" (2.54mm) mating pitch
• Row configuration: 2 rows with 0.100" (2.54mm) row spacing
• Mounting method: Through hole solder termination
• Contact material: Phosphor bronze
• Insulation material: Liquid Crystal Polymer (LCP)
• Operating temperature range: -55°C ~ 125°C
• Current rating: 4.7A per contact
• Fastening type: Push-pull
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 compliant

Distinguishing Parameter: The primary difference between these parts is the contact finish specification. The SSW-122-01-L-D features tin post finish, while the SSW-122-01-G-D features gold post finish with increased mating finish thickness (20.0µin versus 10.0µin). Both maintain gold mating contact finish, ensuring signal integrity and corrosion resistance at the mating interface.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-122-01-L-D and SSW-122-01-G-D maintain Active product status with identical ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends on post-finish requirements for your application. The SSW-122-01-L-D with tin post finish is suitable for standard solder termination applications. The SSW-122-01-G-D with gold post finish provides enhanced corrosion resistance and is appropriate for applications requiring extended shelf life or exposure to corrosive environments. Both connectors are electrically and mechanically equivalent across all critical parameters including position count, pitch, current rating, and operating temperature range. Inventory availability shows both parts in stock with comparable quantities.

Frequently Asked Questions (FAQ)

Q: Can SSW-122-01-G-D replace SSW-122-01-L-D in my application?

A: Yes, provided your application does not specifically require tin post finish. The SSW-122-01-G-D is mechanically and electrically compatible, with the primary difference being the gold post finish instead of tin. Both connectors share identical pitch, position count, current rating, and operating temperature specifications.

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

A: Tin post finish is suitable for standard PCB assembly and solder termination. Gold post finish provides superior corrosion resistance and is preferred in applications with extended storage periods or exposure to humid or corrosive environments. Both finishes are compatible with standard solder processes.

Q: Are the mating contact finishes identical between these parts?

A: Both parts feature gold mating contact finish. The SSW-122-01-G-D has increased mating finish thickness (20.0µin versus 10.0µin), providing additional durability for high-cycle mating applications.

Q: Do these connectors require any special handling or storage considerations?

A: Both connectors are ROHS3 compliant with Moisture Sensitivity Level not applicable, indicating standard handling and storage procedures are sufficient. No special precautions beyond standard component storage are required.

Q: What is the mechanical footprint compatibility between these parts?

A: Both connectors are mechanically identical with matching insulation height (0.335"), contact length (0.104"), and through-hole mounting specifications. PCB layout and mating connector compatibility are fully interchangeable.
