Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TOLC-150-32-F-Q is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Header, Elevated; 4-row, 200-position layout
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Electrical Characteristics: 2.4A per contact current rating; gold-plated phosphor bronze contacts
• Mechanical Interface: Surface mount termination; push-pull fastening; shrouded 4-wall construction
• Environmental Compliance: Operating temperature range -55°C ~ 125°C; UL94 V-0 flammability rating; ROHS3 compliance
• Contact Geometry: Square contact shape; 0.100" (2.54mm) mating contact length; 0.442" (11.23mm) insulation height

The identified substitute part maintains all critical parameters while introducing a board guide feature enhancement. This addition does not compromise electrical or mechanical compatibility and provides improved mechanical stability during mating operations.

Parameter Comparison

Engineering Selection Recommendations

Both TOLC-150-32-F-Q and TOLC-150-32-F-Q-A are active production components from Samtec Inc. with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts depends on application-specific requirements:

TOLC-150-32-F-Q is suitable for applications where standard shrouded 4-wall construction meets mechanical alignment requirements without additional guidance features.

TOLC-150-32-F-Q-A incorporates a board guide feature, providing enhanced mechanical stability during connector mating operations. This variant is appropriate for applications requiring improved alignment precision or where repeated mating cycles demand additional mechanical support.

Both parts maintain identical current ratings (2.4A per contact), operating temperature range (-55°C ~ 125°C), contact geometry, and termination specifications. Inventory availability differs: TOLC-150-32-F-Q has 1106 units in stock, while TOLC-150-32-F-Q-A has 751 units available.

Frequently Asked Questions (FAQ)

Q: Are TOLC-150-32-F-Q and TOLC-150-32-F-Q-A electrically interchangeable?
