SSW-122-01-S-D Equivalent & Substitute Parts

Part Overview

The SSW-122-01-S-D is a 44-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently active in production with 1048 units in stock. Substitute parts are necessary when addressing supply constraints, packaging requirements, or specific application compatibility needs while maintaining electrical and mechanical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-122-01-S-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: All substitutes must be 44-position receptacle connectors
• Pitch & Row Configuration: Mating pitch of 0.100" (2.54mm) with 2-row spacing at 0.100" (2.54mm) is mandatory
• Mounting & Termination: Through-hole solder termination with push-pull fastening required
• Contact Finish: Gold-plated mating contacts with 30.0µin (0.76µm) thickness
• Insulation: Black color insulation
• Regulatory Compliance: ROHS3 compliance required

The two substitute parts listed—TE Connectivity AMP Connectors 2-534206-2 and 7-534206-2—meet these core electrical and mechanical requirements. Variations in insulation material, contact post finish, and operating temperature range do not preclude substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity AMP Connectors substitutes (2-534206-2 and 7-534206-2) are active production parts with ROHS3 compliance, meeting regulatory requirements equivalent to the main part. The 7-534206-2 variant provides additional assurance through explicit UL94 V-0 flammability certification and confirmed REACH Unaffected status, aligning more closely with the main part's compliance profile. The 2-534206-2 variant offers higher inventory availability (1480 units) but carries vendor-undefined REACH status and lacks specified flammability rating documentation.

Both substitutes operate across an extended temperature range (-65°C to 125°C versus -55°C to 125°C), providing broader thermal performance. However, both substitutes are rated at 2A per contact compared to the main part's 4.7A rating. This reduced current capacity must be evaluated against application requirements. Insulation height and contact post length differ slightly between the main part and substitutes, requiring PCB layout verification for mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can 2-534206-2 and 7-534206-2 be used interchangeably with SSW-122-01-S-D?

A: Both parts meet the core substitution criteria: 44-position receptacle configuration, 0.100" (2.54mm) pitch, 2-row spacing, through-hole solder termination, push-pull fastening, and gold-plated mating contacts at 30.0µin thickness. Mechanical fit on PCB must be verified due to differences in insulation height (0.320" versus 0.335") and contact post length (0.115" versus 0.104").

Q: What is the impact of the reduced current rating on substitutes?

A: The substitute parts are rated at 2A per contact versus 4.7A for the main part. Applications requiring current levels above 2A per contact cannot use these substitutes. Circuit design must be reviewed to confirm compatibility with the lower current rating.

Q: How do packaging differences affect part selection?

A: The main part is supplied in bulk packaging, while both substitutes are supplied in tube packaging. Tube packaging may impose minimum order quantities or affect handling procedures. Verify packaging compatibility with procurement and assembly processes.

Q: Are there temperature range implications?

A: Both substitutes operate from -65°C to 125°C, extending the lower temperature limit by 10°C compared to the main part's -55°C to 125°C range. This provides additional thermal margin for applications operating at lower temperatures.

Q: What compliance differences exist between the substitutes?

A: The 7-534206-2 provides explicit UL94 V-0 flammability certification and confirmed REACH Unaffected status. The 2-534206-2 lacks specified flammability rating and carries vendor-undefined REACH status. Applications requiring documented flammability compliance should prioritize 7-534206-2.

Q: Do insulation material differences affect electrical performance?

A: The main part uses Liquid Crystal Polymer (LCP) insulation, while substitutes use Polyester, Glass Filled insulation. Both materials are suitable for the specified operating temperature range and electrical requirements. Material selection does not preclude substitution when other parameters align.
