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

Part Overview

The SS-110-G-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. Substitute parts become necessary when the primary part reaches end-of-life status, supply constraints occur, or design requirements necessitate alternative form factors while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS-110-G-1A is determined by the following critical parameters:

• Number of Positions: Must be 10 positions to maintain pin count compatibility
• Pitch - Mating: Must be 0.100" (2.54mm) to ensure mechanical and electrical alignment with mating connectors
• Mounting Type: Must be through-hole to maintain PCB assembly compatibility
• Contact Finish - Mating: Must be gold to preserve electrical performance and contact reliability
• Operating Temperature Range: Must support -55°C ~ 125°C minimum to meet application requirements
• Termination Method: Must be solder to maintain assembly process compatibility

The substitute part 1814655-5 (TE Connectivity AMP Connectors) meets these critical parameters. While classified as a SIP socket rather than a rectangular connector strip, it provides equivalent electrical and mechanical functionality for 10-position, 0.100" pitch applications with gold-plated contacts and through-hole solder termination.

Parameter Comparison

Engineering Selection Recommendations

The SS-110-G-1A remains the primary selection for new designs due to its active product status and ROHS3 compliance. The 1814655-5 serves as a functional equivalent for applications requiring 10-position, 0.100" pitch socket connectivity with gold-plated contacts and through-hole termination. However, the 1814655-5 is classified as obsolete, which may impact long-term availability and supply chain reliability. Selection between these parts should be based on current inventory requirements, supply chain constraints, and design timeline considerations. Both parts meet identical electrical and mechanical specifications for pitch, contact finish, operating temperature, and termination method.

Frequently Asked Questions (FAQ)

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

A: The 1814655-5 provides electrical and mechanical compatibility for applications requiring 10-position, 0.100" pitch socket connectivity. Both parts feature identical mating pitch, gold-plated contacts, beryllium copper contact material, and -55°C ~ 125°C operating temperature range. Physical form factor differences (SIP socket versus rectangular connector strip) may require PCB layout verification.

Q: What are the key compatibility criteria for substitution?

A: Substitution eligibility is determined by: 10-position count, 0.100" (2.54mm) mating pitch, through-hole mounting, gold contact finish, solder termination, and -55°C ~ 125°C operating temperature support. Both parts meet these criteria.

Q: Why is the 1814655-5 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production by TE Connectivity. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. The SS-110-G-1A is recommended for new designs requiring assured long-term availability.

Q: Are there differences in contact finish thickness between these parts?

A: The SS-110-G-1A specifies 30.0µin (0.76µm) mating contact finish thickness, while the 1814655-5 specifies 29.5µin (0.75µm). These values are functionally equivalent for standard applications.

Q: What is the difference between the housing materials?

A: The SS-110-G-1A uses Polybutylene Terephthalate (PBT) glass-filled material, while the 1814655-5 uses thermoplastic polyester. Both materials provide adequate insulation and mechanical support for the specified operating temperature range and electrical requirements.
