TOLC-105-12-S-Q-LC Equivalent & Substitute Parts

Part Overview

The TOLC-105-12-S-Q-LC is an active Samtec Inc. rectangular connector header from the FOURRAY™ TOLC series. This surface mount quad row terminal features 20 positions with 0.050" (1.27mm) pitch and elevated header configuration for board-to-board applications. The connector is designed for solder termination with push-pull fastening and shrouded 4-wall construction. Substitute parts are identified to provide alternative options for applications requiring different mated stacking heights or inventory availability while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TOLC-105-12-S-Q-LC are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameter is the mated stacking height, which varies between the main part and substitute options while all other critical specifications remain identical.

The following parameters must remain constant for valid substitution:

• Manufacturer: Samtec Inc.
• Series: FOURRAY™ TOLC
• Number of Positions: 20
• Number of Rows: 4
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Header, Elevated
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 2.4A per Contact
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The variable parameter allowing substitution is:

• Insulation Height / Mated Stacking Height

Parameter Comparison

Engineering Selection Recommendations

Both TOLC-105-12-S-Q-LC and TOLC-105-32-S-Q-LC are active products from Samtec Inc. with identical electrical specifications and compliance certifications. Selection between these parts depends on application-specific mated stacking height requirements.

The TOLC-105-12-S-Q-LC provides an 8mm mated stacking height with 0.285" (7.25mm) insulation height, suitable for applications with space constraints or lower profile requirements.

The TOLC-105-32-S-Q-LC provides a 12mm mated stacking height with 0.442" (11.23mm) insulation height, suitable for applications requiring greater clearance or elevated connector positioning.

Both parts maintain identical electrical performance, current ratings, operating temperature ranges, and compliance with ROHS3 and UL94 V-0 standards. Inventory availability differs between the two options.

Frequently Asked Questions (FAQ)

Q: Can TOLC-105-32-S-Q-LC be used as a direct replacement for TOLC-105-12-S-Q-LC?

A: Substitution is possible only if the application accommodates the increased mated stacking height of 12mm versus 8mm. All electrical and mechanical specifications remain identical. PCB layout and mating connector clearance must be verified for the specific application.

Q: What is the primary difference between these substitute parts?

A: The primary difference is the mated stacking height and corresponding insulation height. TOLC-105-12-S-Q-LC has an 8mm stacking height, while TOLC-105-32-S-Q-LC has a 12mm stacking height. All other parameters, including contact pitch, number of positions, current rating, and operating temperature, are identical.

Q: Are both parts RoHS compliant?

A: Yes, both TOLC-105-12-S-Q-LC and TOLC-105-32-S-Q-LC are ROHS3 compliant and carry UL94 V-0 material flammability ratings.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Can these connectors handle the same current?

A: Yes, both parts are rated for 2.4A per contact with identical contact material (Phosphor Bronze) and gold plating specifications.
