Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ED105/2DS is determined by the following critical parameters:

• Position count and pitch: Must maintain 2 positions at 0.197" (5.00mm) spacing for PCB footprint compatibility
• Mating orientation: Must be vertical with board configuration for mechanical fit
• Wire termination method: Must use screw-based termination with leaf spring and wire guard
• Mounting type: Must be through-hole for PCB integration
• Wire gauge compatibility: Must accept 14-22 AWG conductors
• Operating temperature range: Must support -30°C to 105°C minimum
• Screw thread specification: Must use M3 thread for assembly compatibility
• Regulatory compliance: Must maintain RoHS3 and REACH compliance status

The substitute part OSTTB020161 meets these core mechanical and functional requirements. Variations in current rating (16 A vs. 15 A), voltage rating (250 V vs. 300 V), housing material, contact plating, and torque specification are secondary parameters that do not prevent substitution when the primary criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both ED105/2DS and OSTTB020161 maintain Active product status and full compliance with RoHS3 and REACH regulations. Selection between these parts is based on application voltage and current requirements:

• ED105/2DS: Select when circuit design specifies 300 V operation or requires the 15 A current rating as a design constraint
• OSTTB020161: Select when 250 V and 16 A ratings satisfy circuit requirements; this part offers higher current capacity and greater inventory availability (2962 pcs vs. 993 pcs)

Both parts share identical mechanical footprints, wire gauge compatibility, operating temperature range, and screw specifications, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can OSTTB020161 replace ED105/2DS in a 300 V circuit? A: No. The OSTTB020161 is rated for 250 V maximum. Circuit voltage must not exceed the substitute part's voltage rating.

Q: Are the PCB footprints identical between these parts? A: Yes. Both parts maintain 2 positions at 0.197" (5.00mm) pitch with M3 through-hole mounting, ensuring identical PCB layout compatibility.

Q: Does the difference in housing material affect substitution? A: Housing material (Polyamide vs. Thermoplastic) does not affect electrical or mechanical compatibility for PCB mounting applications. Both materials meet the operating temperature range of -30°C to 105°C.

Q: What is the impact of different torque specifications? A: ED105/2DS specifies 0.5 Nm torque; OSTTB020161 specifies 0.3 Nm. Assembly procedures must follow the torque specification of the installed part to ensure proper wire clamping without over-tightening.

Q: Are both parts suitable for 14-22 AWG wire? A: Yes. Both parts accept the same wire gauge range, ensuring compatibility with standard PCB wiring practices.

Q: What is the difference in contact plating? A: ED105/2DS uses brass contacts; OSTTB020161 uses tin-plated contacts. Both materials provide adequate electrical conductivity and corrosion resistance for standard applications.
