Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TOLC-150-22-L-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; phosphor bronze contact material with gold finish
• 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; 0.364" (9.25mm) insulation height

The substitute part TOLC-150-22-L-Q-A maintains full equivalence across all critical parameters. Differences are limited to non-functional features (Board Guide addition) that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TOLC-150-22-L-Q and TOLC-150-22-L-Q-A are Active status products with full ROHS3 compliance and UL94 V-0 flammability certification. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

The TOLC-150-22-L-Q-A includes a Board Guide feature not present in the base TOLC-150-22-L-Q. This feature provides mechanical alignment assistance during mating but does not alter electrical performance, current capacity, or thermal characteristics. Selection between these parts depends on assembly process requirements and mechanical alignment preferences rather than electrical or environmental factors.

Both parts are suitable for applications requiring 200-position, 4-row board-to-board connectivity with 0.050" pitch at 2.4A per contact within the -55°C to 125°C operating range. Inventory availability is 1100 pcs for TOLC-150-22-L-Q and 729 pcs for TOLC-150-22-L-Q-A.

Frequently Asked Questions (FAQ)

Q: Are TOLC-150-22-L-Q and TOLC-150-22-L-Q-A electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including contact material (phosphor bronze), contact finish (gold at 10.0µin thickness), current rating (2.4A per contact), and operating temperature range (-55°C ~ 125°C). They are direct electrical substitutes.

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

A: The TOLC-150-22-L-Q-A includes a Board Guide feature for mechanical alignment during mating. All other mechanical and electrical parameters are identical. The Board Guide is a non-functional enhancement that does not affect connector performance or compatibility.

Q: Can I use TOLC-150-22-L-Q-A as a drop-in replacement for TOLC-150-22-L-Q?

A: Yes. The TOLC-150-22-L-Q-A maintains full mechanical and electrical compatibility with the TOLC-150-22-L-Q. The addition of the Board Guide does not prevent mating with existing receptacles or affect PCB footprint requirements.

Q: Do both parts require special handling during assembly?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required. Standard surface mount assembly processes apply.

Q: What is the mating pitch for these connectors?

A: Both connectors feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing across 4 rows, accommodating 200 total positions.

Q: Are these connectors RoHS compliant?

A: Yes. Both TOLC-150-22-L-Q and TOLC-150-22-L-Q-A are ROHS3 compliant and carry UL94 V-0 flammability certification.
