SDL-104-T-12 Equivalent & Substitute Parts

Part Overview

The SDL-104-T-12 is an 8-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features through-hole solder termination, dual-row configuration, and gold-plated mating contacts. The part is currently active in production with 854 units in stock. Substitute parts are identified when design requirements allow for alternative contact finish specifications while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDL-104-T-12 is determined by equivalence in the following critical parameters:

• Connector Type & Style: Receptacle, board-to-board configuration
• Position Count & Arrangement: 8 positions in 2-row dual configuration
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Mating Contact Finish: Gold plating at 30.0µin (0.76µm) thickness
• Insulation & Mechanical Dimensions: LCP insulation, 0.095" height, circular contacts
• Contact Material: Beryllium copper base material
• Environmental Ratings: Operating temperature -55°C to 125°C, MSL 1, ROHS3 and REACH compliance

The SDL-104-G-12 qualifies as a substitute because it maintains all critical parameters. The difference in post contact finish (gold plating at 10.0µin versus unspecified in the main part) does not affect substitutability for board-to-board receptacle applications where mating contact performance is the primary functional requirement.

Parameter Comparison

Engineering Selection Recommendations

Both SDL-104-T-12 and SDL-104-G-12 are active production parts from Samtec Inc. with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and post contact finish requirements specific to your application.

The SDL-104-T-12 is currently stocked at 854 units. The SDL-104-G-12 is available with 730 units in inventory and includes specified gold plating on the post contacts at 10.0µin thickness, providing additional corrosion protection on the solder-side termination.

Both parts meet the same environmental and regulatory requirements for board-to-board receptacle connector applications within the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can SDL-104-G-12 be used as a direct replacement for SDL-104-T-12?

A: Yes. Both parts share identical specifications for all critical connector parameters including position count, pitch, mounting type, mating contact finish, insulation material, and operating temperature range. The difference in post contact finish does not affect functional compatibility in board-to-board applications.

Q: What is the difference between SDL-104-T-12 and SDL-104-G-12?

A: The primary difference is the post contact finish specification. SDL-104-G-12 specifies gold plating at 10.0µin (0.25µm) on the post contacts, while SDL-104-T-12 does not specify post contact finish. Both maintain identical mating contact specifications and all other mechanical and electrical parameters.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both connectors have identical mounting dimensions, pitch spacing (0.100"), insulation height (0.095"), and contact length specifications. They are mechanically and electrically interchangeable for through-hole solder termination on standard PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SDL-104-T-12 and SDL-104-G-12 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings.

Q: Which part should I select based on availability?

A: Selection should be based on your inventory requirements and delivery timeline. SDL-104-T-12 has 854 units in stock, while SDL-104-G-12 has 730 units available. Both are active production parts with equivalent functional performance.
