Engineering Selection Recommendations

All three parts—929852-01-25-RB, 2-215307-5, and BCS-125-F-D-TE—are active products with UL94 V-0 flammability ratings and RoHS compliance. Selection between these parts should be based on the following factors:

929852-01-25-RB (3M): Primary choice when 3M series compatibility is required. Supports 2A current rating and 1500V voltage rating. Operating temperature range -40°C to 105°C. 882 units currently in stock.

2-215307-5 (TE Connectivity AMPMODU HV-100): Alternative when TE Connectivity ecosystem integration is preferred. ROHS3 compliant. 1361 units in stock. Kinked pin termination provides enhanced mechanical retention. Operating temperature range not specified.

BCS-125-F-D-TE (Samtec Tiger Claw™ BCS): Option for applications requiring extended temperature range (-55°C to 125°C) and higher current capacity (4.6A per contact). ROHS3 compliant. Liquid Crystal Polymer insulation material. 1010 units in stock.

All parts meet the core electrical and mechanical requirements for 50-position, 0.100" pitch board-to-board rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. All three parts share identical mating pitch (0.100"), position count (50), row configuration (2 rows), and contact finish (gold). They are electrically compatible for board-to-board applications.

Q: What are the key differences between these connectors? A: Primary differences include insulation material (PCT/Polyester vs. LCP), insulation height (0.325" vs. 0.276" vs. 0.290"), contact material (Copper Alloy vs. Phosphor Bronze), and operating temperature ranges. The BCS-125-F-D-TE offers the widest temperature range and highest current rating.

Q: Can I use these parts interchangeably on the same PCB? A: Mechanical compatibility depends on PCB footprint design. Variations in insulation height (0.325" vs. 0.276" vs. 0.290") and contact length may affect board layout. Verify PCB hole spacing and mounting clearances before substitution.

Q: What packaging formats are available? A: 929852-01-25-RB is supplied in Bulk packaging. 2-215307-5 is supplied in Tray packaging. BCS-125-F-D-TE is supplied in Tube packaging. Packaging format affects handling and storage requirements.

Q: Which part should I select for high-temperature applications? A: BCS-125-F-D-TE supports -55°C to 125°C operating temperature, providing the widest range. The 929852-01-25-RB operates -40°C to 105°C. Operating temperature range for 2-215307-5 is not specified.

Q: Are all parts RoHS compliant? A: Yes. 929852-01-25-RB is RoHS Compliant. Both 2-215307-5 and BCS-125-F-D-TE are ROHS3 Compliant.
