Key Parameters

Substitute Part Grouping Explanation

Substitution for the TOLC-140-32-F-Q is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Number of positions (160), number of rows (4), mating pitch (0.050"), row spacing (0.050"), contact type (Male Pin), and current rating (2.4A per Contact)
• Mechanical Compatibility: Connector type (Header, Elevated), mounting type (Surface Mount), termination method (Solder), fastening type (Push-Pull), and shrouding configuration (Shrouded - 4 Wall)
• Environmental & Compliance: Operating temperature range (-55°C ~ 125°C), material flammability rating (UL94 V-0), RoHS3 compliance, and moisture sensitivity level (MSL 1)
• Physical Dimensions: Insulation height (0.442"), contact length - mating (0.100"), mated stacking heights (12mm), and contact shape (Square)
• Material Specifications: Contact material (Phosphor Bronze), insulation material (Liquid Crystal Polymer), contact finish (Gold), and contact finish thickness (3.00µin)

The substitute part TOLC-140-32-F-Q-K maintains all critical parameters with the addition of Pick and Place feature capability, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both TOLC-140-32-F-Q and TOLC-140-32-F-Q-K are Active status products from Samtec Inc. and maintain full ROHS3 compliance with UL94 V-0 flammability certification. The parts are electrically and mechanically interchangeable across all specified parameters.

The TOLC-140-32-F-Q-K includes Pick and Place feature capability, which provides enhanced manufacturing flexibility for automated assembly processes. This addition does not alter electrical performance, mechanical fit, or environmental operating characteristics.

Selection between these parts should be based on manufacturing process requirements. If automated pick and place assembly is utilized, the TOLC-140-32-F-Q-K is the appropriate choice. For manual assembly or existing production lines without pick and place requirements, either part is suitable.

Both parts carry identical inventory status classifications and are available through standard distribution channels.
