Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDL-118-T-12 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (36)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm mating and row spacing)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Beryllium Copper)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The SDL-118-G-12 meets all substitution criteria as a direct equivalent within the SDL series, with identical mechanical and electrical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

Both SDL-118-T-12 and SDL-118-G-12 are active production parts from Samtec Inc. with identical mechanical interfaces and electrical specifications. Selection between these parts should be based on:

• Product availability and inventory status
• Supply chain lead times
• Post-contact finish requirements (SDL-118-G-12 specifies gold plating on post contacts)
• Design documentation and qualification history

Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility for current and future applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can SDL-118-G-12 be used as a direct replacement for SDL-118-T-12?

A: Yes. Both parts share identical connector type, contact configuration, pitch spacing, mounting method, and termination specifications. The primary difference is the post-contact finish specification on SDL-118-G-12.

Q: What is the difference between SDL-118-T-12 and SDL-118-G-12?

A: The SDL-118-G-12 specifies gold plating on post contacts (10.0µin / 0.25µm thickness), while the SDL-118-T-12 does not specify post-contact finish. Both maintain identical mating contact specifications and all other mechanical and electrical parameters.

Q: Are these connectors compatible with standard 0.100" pitch headers?

A: Yes. Both connectors feature 0.100" (2.54mm) mating pitch and row spacing, compatible with standard dual-row headers of matching position count and configuration.

Q: What is the operating temperature range for these connectors?

A: Both SDL-118-T-12 and SDL-118-G-12 operate across -55°C to 125°C.

Q: Are these parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage and handling.
