SDL-103-T-12 Equivalent & Substitute Parts

Part Overview

The SDL-103-T-12 is a 6-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 operates across -55°C to 125°C. The part is currently active in production with 956 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when design revisions require alternative contact finishes, or when inventory constraints necessitate sourcing from alternative stock positions within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDL-103-T-12 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (6)
• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows at 0.100" spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Mating contact finish (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Beryllium Copper)

The SDL-103-G-12 shares all critical electrical and mechanical parameters with the SDL-103-T-12, making it a direct substitute within the SDL series. Both parts are derived from the same base product number (SDL-103) and maintain identical mating interface specifications.

Parameter Comparison

Engineering Selection Recommendations

The SDL-103-T-12 is the preferred primary selection due to its active product status and higher current inventory availability (956 units). Both parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040).

The SDL-103-G-12 functions as a direct electrical and mechanical equivalent but carries discontinued status at DiGi Electronics. Selection of the SDL-103-G-12 should be limited to applications where existing inventory must be utilized or where design documentation specifically references this part number. The minor difference in post contact finish thickness (10.0µin vs. unspecified) does not affect mating interface performance or electrical characteristics.

For new designs and production builds, the SDL-103-T-12 is the recommended choice to ensure long-term supply chain continuity and compliance with active product lifecycle management.

Frequently Asked Questions (FAQ)

Q: Can SDL-103-G-12 be used as a direct replacement for SDL-103-T-12 in existing assemblies?

A: Yes. Both connectors share identical mating interface specifications, pitch spacing, contact materials, and operating temperature ranges. The electrical and mechanical compatibility is complete.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. SDL-103-T-12 is active in production, while SDL-103-G-12 is discontinued at DiGi Electronics. Both parts are manufactured by Samtec Inc. within the SDL series and derive from the same base product number (SDL-103). A secondary difference exists in post contact finish specification: SDL-103-G-12 specifies gold plating at 10.0µin thickness on the post, while SDL-103-T-12 does not specify this parameter.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and regulatory classifications. Moisture sensitivity level is equivalent (MSL 1 - Unlimited) for both variants.

Q: Which part should be selected for new product designs?

A: The SDL-103-T-12 should be selected for new designs due to its active product status and higher inventory availability. This ensures design continuity and reduces supply chain risk.

Q: Can these connectors be intermated with other Samtec SDL series parts?

A: Intermatability is determined by pitch spacing and contact configuration. Both the SDL-103-T-12 and SDL-103-G-12 feature 0.100" (2.54mm) pitch spacing and 6-position, 2-row configuration, making them compatible with mating connectors designed for these specifications within the SDL series.
