SSQ-103-21-S-D Equivalent & Substitute Parts

Part Overview

The SSQ-103-21-S-D is a 6-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 687 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where form factor and performance requirements match.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSQ-103-21-S-D are qualified based on the following critical parameters that must match or exceed the original specification:

• 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
• Termination method: Solder
• Fastening type: Push-pull
• Contact finish on mating surface: Gold
• Contact finish thickness on mating surface: 30.0µin (0.76µm)
• Insulation color: Black
• Material flammability rating: UL94 V-0

The identified substitutes are TE Connectivity AMP Connectors parts 5-534206-3 and 534206-3 from the AMPMODU Mod II series. Both parts satisfy all critical electrical and mechanical parameters required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitute parts meet the core electrical and mechanical requirements for direct replacement of the SSQ-103-21-S-D. Selection between the two TE Connectivity options depends on compliance requirements:

5-534206-3 is recommended for applications requiring RoHS compliance certification, as it carries explicit RoHS Compliant status and MSL rating of 1 (Unlimited).

534206-3 is suitable for applications where RoHS compliance is not a requirement, though it carries REACH Affected status and does not specify a flammability rating.

Both parts operate across an extended temperature range (-65°C to 125°C) compared to the original part (-55°C to 125°C), providing additional thermal margin. The TE Connectivity parts feature slightly longer contact post length (0.115" versus 0.104") and marginally reduced insulation height (0.320" versus 0.335"), which may require verification in space-constrained PCB layouts. All three parts share identical mating pitch, row spacing, contact finish specifications, and push-pull fastening mechanism.

Frequently Asked Questions (FAQ)

Q: Can 5-534206-3 and 534206-3 be used interchangeably with SSQ-103-21-S-D?

A: Yes. Both TE Connectivity parts satisfy all critical substitution parameters: 6-position receptacle configuration, 0.100" (2.54mm) pitch, 2-row layout, through-hole solder termination, push-pull fastening, and gold-plated mating contacts at 30.0µin thickness. Physical dimensions vary slightly in insulation height and contact post length, requiring verification in space-constrained applications.

Q: What are the key differences between the two TE Connectivity substitutes?

A: The primary difference is compliance status. Part 5-534206-3 carries explicit RoHS Compliant certification and MSL 1 rating, while 534206-3 does not specify RoHS compliance and carries REACH Affected status. Both parts are electrically and mechanically equivalent for connector function.

Q: Are there packaging considerations when switching from SSQ-103-21-S-D to the TE Connectivity alternatives?

A: Yes. The original Samtec part ships in bulk packaging, while both TE Connectivity substitutes are supplied in tube packaging. Inventory levels differ significantly: 687 units for SSQ-103-21-S-D versus 26,963 units for 5-534206-3 and 9,293 units for 534206-3.

Q: Do the substitute parts support the same voltage and current ratings?

A: The SSQ-103-21-S-D specifies 465VAC and 655VDC voltage ratings with no current rating listed. The TE Connectivity substitutes specify 2A current rating with no voltage rating provided. Verify that both voltage and current specifications meet application requirements before substitution.

Q: What is the impact of different insulation materials on substitution?

A: The SSQ-103-21-S-D uses Liquid Crystal Polymer (LCP) insulation, while both TE Connectivity substitutes use Polyester, Glass Filled insulation. Both materials meet UL94 V-0 flammability requirements (where specified) and are suitable for board-to-board and cable applications. Material selection should be verified against specific environmental and thermal requirements.

Q: Are there temperature range differences to consider?

A: The SSQ-103-21-S-D operates from -55°C to 125°C, while both TE Connectivity substitutes operate from -65°C to 125°C. The extended lower temperature range of the substitutes provides additional thermal margin and does not restrict substitution in applications using the original part's temperature range.
