SSW-110-21-S-D Equivalent & Substitute Parts

Part Overview

The SSW-110-21-S-D is a 20-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts, forked contact design, and push-pull fastening. The product is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design requirements and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-110-21-S-D is determined by the following critical parameters:

Connector Type & Position Count: Must be a 20-position receptacle connector
Pitch & Row Configuration: Must maintain 0.100" (2.54mm) mating pitch with 2-row configuration and 0.100" row spacing
Mounting & Termination: Must support through-hole solder termination
Fastening & Contact Finish: Must feature push-pull fastening with gold-plated mating contacts at 30.0µin thickness
Contact Material & Shape: Must use phosphor bronze with square contact geometry
Electrical Performance: Current rating and operating temperature range must meet or exceed application requirements

The substitute part 1-534998-0 (TE Connectivity AMP Connectors AMPMODU Mod IV series) satisfies these core substitution criteria, enabling direct functional replacement in board-to-board and cable interconnect applications.

Engineering Selection Recommendations

The 1-534998-0 substitute part is functionally compatible with the SSW-110-21-S-D for applications where the following conditions are met:

Electrical Compatibility: The substitute part supports a 2A current rating per contact, compared to the original 4.7A rating. Selection of this substitute requires verification that application current requirements do not exceed 2A per contact.

Temperature Range: The substitute part extends the lower operating temperature limit to -65°C, providing broader environmental coverage than the original -55°C specification.

Compliance Considerations: The original SSW-110-21-S-D is ROHS3 compliant. The substitute 1-534998-0 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this compliance difference.

Product Availability: The substitute part is currently active in inventory (9638 pcs), whereas the original is discontinued, making it the practical choice for new procurement and ongoing production.

Mechanical Fit: Both connectors share identical pitch, row spacing, mounting type, and fastening mechanism, ensuring direct mechanical interchangeability in PCB layouts and cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 1-534998-0 be used as a direct replacement for the SSW-110-21-S-D?

A: Yes, for applications where the current requirement per contact does not exceed 2A. Both connectors share identical mating pitch (0.100"), row configuration (2 rows at 0.100" spacing), 20-position count, through-hole solder termination, push-pull fastening, and gold-plated mating contacts. Mechanical and electrical interchangeability is confirmed for these parameters.

Q: What is the primary difference between these two connectors?

A: The main difference is current rating: the SSW-110-21-S-D supports 4.7A per contact, while the 1-534998-0 supports 2A per contact. Additionally, the insulation materials differ (LCP vs. thermoplastic glass-filled), and RoHS compliance status differs (ROHS3 compliant vs. non-compliant).

Q: Does the substitute part meet RoHS requirements?

A: No. The 1-534998-0 is RoHS non-compliant, whereas the original SSW-110-21-S-D is ROHS3 compliant. Applications requiring RoHS compliance must evaluate this difference against regulatory requirements.

Q: Are there packaging differences between these connectors?

A: The SSW-110-21-S-D packaging is not specified in available data. The 1-534998-0 is supplied in tube packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What is the temperature operating range for each connector?

A: The SSW-110-21-S-D operates from -55°C to 125°C. The 1-534998-0 operates from -65°C to 125°C, providing a 10°C lower temperature limit.

Q: Can I use the 1-534998-0 in a high-current application requiring 4.7A per contact?

A: No. The 1-534998-0 is rated for 2A per contact maximum. Applications requiring 4.7A per contact must use the original SSW-110-21-S-D or identify an alternative substitute with matching current specifications.
