Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-103-21-S-D-LL is determined by strict alignment of the following critical parameters:

• Connector type: Receptacle
• Number of positions: 6
• Pitch spacing: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing: 0.100" (2.54mm)
• Mounting type: Through hole
• Fastening type: Push-pull
• Contact finish (mating): Gold
• Contact finish thickness (mating): 30.0µin (0.76µm)
• Insulation color: Black
• Material flammability rating: UL94 V-0

The substitute part 5-534206-3 (TE Connectivity AMP Connectors) meets all critical substitution criteria. Both connectors share identical pitch, row configuration, mounting method, fastening mechanism, and gold contact finish specifications. Both maintain UL94 V-0 flammability compliance and operate within overlapping temperature ranges. Differences in contact type designation (forked vs. female socket), insulation material composition, and current rating specifications are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-103-21-S-D-LL and 5-534206-3 maintain active production status and comply with applicable environmental and safety standards. The SSW-103-21-S-D-LL carries ROHS3 compliance, while the 5-534206-3 carries RoHS compliance. Both connectors are UL94 V-0 rated and feature phosphor bronze contacts with gold mating surfaces at 30.0µin thickness.

Selection between these parts should account for the following provided specifications: the SSW-103-21-S-D-LL supports a current rating of 4.7A per contact, while the 5-534206-3 supports 2A per contact. The SSW-103-21-S-D-LL uses Liquid Crystal Polymer insulation material, whereas the 5-534206-3 uses polyester with glass reinforcement. Operating temperature ranges differ slightly, with the 5-534206-3 extending to -65°C minimum compared to -55°C for the SSW-103-21-S-D-LL. Physical dimensions including insulation height and contact post length vary between the two designs.

Frequently Asked Questions (FAQ)

Q: Can the 5-534206-3 directly replace the SSW-103-21-S-D-LL in all applications?

A: Both connectors share identical pitch spacing (0.100"), row configuration (2 rows), mounting type (through hole), and fastening mechanism (push-pull). However, the current rating differs: SSW-103-21-S-D-LL supports 4.7A per contact while 5-534206-3 supports 2A per contact. Applications requiring current levels above 2A per contact must use the SSW-103-21-S-D-LL. Physical dimensions also differ, requiring PCB layout verification.

Q: What are the key differences in insulation material between these connectors?

A: The SSW-103-21-S-D-LL uses Liquid Crystal Polymer (LCP) insulation, while the 5-534206-3 uses polyester with glass reinforcement. Both materials meet UL94 V-0 flammability requirements. Material selection may affect mechanical properties and environmental resistance in specific applications.

Q: Do both connectors meet RoHS requirements?

A: The SSW-103-21-S-D-LL is ROHS3 compliant. The 5-534206-3 is RoHS compliant. Both meet lead-free and restricted substance requirements for their respective compliance standards.

Q: How do the operating temperature ranges compare?

A: The SSW-103-21-S-D-LL operates from -55°C to 125°C. The 5-534206-3 operates from -65°C to 125°C, providing a wider low-temperature operating range. Both share the same maximum operating temperature of 125°C.

Q: What packaging differences exist between these parts?

A: The SSW-103-21-S-D-LL is supplied in bulk packaging, while the 5-534206-3 is supplied in tube packaging. Packaging selection may affect handling, storage, and procurement workflows.

Q: Are the contact post dimensions identical?

A: No. The SSW-103-21-S-D-LL has a contact post length of 0.104" (2.64mm), while the 5-534206-3 has a contact post length of 0.115" (2.92mm). Insulation height also differs: 0.335" (8.51mm) for SSW-103-21-S-D-LL versus 0.320" (8.13mm) for 5-534206-3. These dimensional differences require PCB design verification before substitution.
