SDL-112-T-11 Equivalent & Substitute Parts

Part Overview

The SDL-112-T-11 is a 24-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, gold-plated mating contacts, and push-pull fastening. The part is currently active in production with 776 units in stock. Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when design flexibility is required, or when alternative sourcing options are needed to optimize supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDL-112-T-11 is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (24)
• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows at 0.100" spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Mating contact finish (Gold)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Beryllium Copper)
• Operating temperature range (-55°C ~ 125°C)

The SDL-112-G-11 meets all critical substitution criteria as a part within the same SDL series from Samtec Inc. Both parts share identical mechanical and electrical specifications for mating interface, row configuration, pitch, and contact geometry. The primary distinction is the contact finish on the post termination, where SDL-112-G-11 includes gold plating on the post contact.

Parameter Comparison

Engineering Selection Recommendations

The SDL-112-G-11 is a valid substitute for the SDL-112-T-11 based on compliance and product specifications. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The SDL-112-T-11 is currently active in production with established inventory availability. The SDL-112-G-11 is discontinued at DiGi Electronics, which may impact long-term sourcing reliability.

Selection between these parts should be based on supply chain requirements and availability. The SDL-112-T-11 is recommended for new designs requiring sustained production support. The SDL-112-G-11 remains functionally equivalent for applications where existing inventory or alternative distribution channels provide adequate supply.

Frequently Asked Questions (FAQ)

Q: Can SDL-112-G-11 be used as a direct replacement for SDL-112-T-11?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing, row configuration, contact geometry, and electrical operating parameters. The parts are mechanically and electrically interchangeable within the same circuit design.

Q: What is the difference between SDL-112-T-11 and SDL-112-G-11?

A: The primary difference is the contact finish on the post termination. SDL-112-G-11 includes gold plating (10.0µin) on the post contact, while SDL-112-T-11 does not specify post contact finish. Both maintain gold plating on mating contacts at 30.0µin thickness.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, maintain MSL 1 (Unlimited) moisture sensitivity rating, and carry identical REACH and ECCN classifications.

Q: Why is SDL-112-G-11 discontinued?

A: The part is discontinued at DiGi Electronics. Availability through alternative distributors or direct manufacturer channels may still be possible. Confirm current sourcing options before committing to this part for production designs.

Q: What are the critical parameters for substitution compatibility?

A: Substitution requires matching connector type (Receptacle), contact type (Female Socket), position count (24), pitch (0.100"), row spacing (0.100"), mounting method (Through Hole), termination (Solder), and fastening type (Push-Pull). Mating contact finish (Gold) and insulation material (LCP) must also align.
