SS-110-T-1A Equivalent & Substitute Parts

Part Overview

The SS-110-T-1A is a 10-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated female socket contacts and is classified as an active product with full inventory availability. Finding equivalent or substitute parts becomes necessary when addressing supply chain requirements, design flexibility, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS-110-T-1A is evaluated based on the following critical parameters that must align for functional compatibility:

• Number of Positions: Must be 10 positions to maintain pin count compatibility
• Pitch - Mating: Must be 0.100" (2.54mm) to ensure mechanical fit with mating connectors
• Mounting Type: Must be through-hole to match PCB assembly requirements
• Contact Finish - Mating: Must be gold to maintain electrical performance and corrosion resistance
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Termination Method: Must be solder-compatible for PCB integration

The substitute part 1814655-5 (TE Connectivity AMP Connectors) meets these core substitution criteria. While classified as a SIP socket rather than a rectangular connector strip, it maintains electrical and mechanical compatibility through matching pitch, position count, gold contact finish, through-hole mounting, and solder termination.

Parameter Comparison

Engineering Selection Recommendations

The SS-110-T-1A remains the primary selection for new designs due to its active product status and ROHS3 compliance. The substitute part 1814655-5 is classified as obsolete, which may impact long-term availability and future procurement. Selection between these parts should be based on:

• Active Product Requirement: SS-110-T-1A is recommended for ongoing production and new designs
• Compliance Alignment: Both parts meet RoHS requirements; SS-110-T-1A offers ROHS3 compliance
• Supply Chain Considerations: SS-110-T-1A has confirmed inventory of 852 pieces; 1814655-5 has 2607 pieces but obsolete status limits future sourcing
• Form Factor Differences: SS-110-T-1A is a rectangular connector strip; 1814655-5 is a SIP socket with closed frame design, which may affect PCB layout and mechanical integration

Frequently Asked Questions (FAQ)

Q: Can 1814655-5 directly replace SS-110-T-1A in existing designs?

A: Electrical and mechanical compatibility is maintained through matching pitch (0.100"), position count (10), gold contact finish, and operating temperature range. However, form factor differences (rectangular strip vs. SIP socket) may require PCB layout verification.

Q: What is the significance of the obsolete status for 1814655-5?

A: Obsolete status indicates the part is no longer in active production. While current inventory exists, future availability cannot be guaranteed. For new designs or long-term production, SS-110-T-1A is the appropriate selection.

Q: Are the contact finish thicknesses equivalent?

A: Yes. SS-110-T-1A specifies 30.0µin (0.76µm) and 1814655-5 specifies 29.5µin (0.75µm), representing negligible difference within standard manufacturing tolerances for gold plating on mating contacts.

Q: Do both parts support the same solder termination process?

A: Yes. Both parts use solder termination and are rated for through-hole PCB assembly. Termination post specifications differ (SS-110-T-1A: 0.360", 1814655-5: 0.114"), which may affect solder joint geometry and should be verified against PCB design specifications.

Q: What compliance certifications apply to each part?

A: SS-110-T-1A is ROHS3 compliant with MSL 1. 1814655-5 is RoHS compliant with MSL 1 and REACH affected status. Both support -55°C ~ 125°C operating temperature range.
