OSTTS06115B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS06115B is a 6-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.138" (3.50mm) pitch spacing. This component is designed for free-hanging in-line applications with screw termination and operates across -40°C to 115°C. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's core specifications, enabling direct functional replacement in applications where the primary part is unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS06115B is determined by strict alignment of the following core parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 6 positions at 0.138" (3.50mm) pitch to ensure mechanical compatibility with mating connectors and PCB layouts.
• Connector Type: Female socket plugs are required to maintain functional equivalence in the circuit interface.
• Mounting Configuration: Free-hanging in-line mounting is mandatory for form factor compatibility.
• Electrical Ratings: Voltage rating of 300 V UL and wire gauge compatibility (16-28 AWG minimum) ensure safe operation within the same electrical environment.
• Operating Temperature Range: -40°C to 115°C operational limits must be met or exceeded.
• Contact Material & Finish: Phosphor bronze with tin plating ensures consistent electrical performance and corrosion resistance.
• Compliance: RoHS3 compliance is required for regulatory alignment.

The substitute part 0395033006 (Molex) meets these core substitution criteria while introducing variations in termination mechanism (rising cage clamp vs. standard screw) and wire entry orientation (90° vs. in-line).

Parameter Comparison

Engineering Selection Recommendations

Primary Part (OSTTS06115B): Recommended for applications requiring in-line wire entry configuration with standard screw termination. Active product status and full inventory availability support immediate deployment.

Substitute Part (0395033006): The Molex 0395033006 provides functional equivalence for 6-position, 3.5mm pitch terminal block applications. Selection of this substitute is appropriate when:

• 90° wire entry orientation aligns with circuit board layout requirements
• Rising cage clamp termination mechanism is acceptable or preferred for the application
• Extended wire gauge support (16-30 AWG) accommodates larger conductor sizes
• Black housing color meets aesthetic or identification requirements
• Polyamide (PA66) housing material is compatible with the operating environment

Both parts maintain RoHS3 compliance, identical electrical ratings (300 V UL), matching operating temperature range (-40°C to 115°C), and phosphor bronze tin-plated contacts. The primary differentiators are wire entry orientation, termination mechanism variant, and housing material composition.

Frequently Asked Questions (FAQ)

Q: Can the 0395033006 directly replace the OSTTS06115B in existing designs?

A: Direct mechanical replacement is possible only if the circuit board layout accommodates 90° wire entry. The OSTTS06115B features in-line wire entry, while the 0395033006 requires perpendicular wire routing. Verify PCB connector orientation before substitution.

Q: Are the screw termination mechanisms interchangeable?

A: Both parts use screw-based termination, but the OSTTS06115B employs standard screw terminals while the 0395033006 uses a rising cage clamp mechanism. Both achieve equivalent electrical connection; however, wire insertion and removal procedures differ slightly. Refer to manufacturer datasheets for specific termination procedures.

Q: What is the impact of different housing materials?

A: The OSTTS06115B uses thermoplastic housing; the 0395033006 uses polyamide (PA66) nylon 6/6. Both materials operate across the specified -40°C to 115°C range. Polyamide offers superior chemical resistance and mechanical strength in high-vibration environments. Select based on environmental exposure requirements.

Q: Does the extended wire gauge range of the 0395033006 affect compatibility?

A: The 0395033006 supports 16-30 AWG versus the OSTTS06115B's 16-28 AWG. This extended range does not create incompatibility; it provides additional flexibility for larger conductor applications. Standard 16-28 AWG wires function identically in both parts.

Q: Are both parts RoHS3 compliant?

A: Yes, both the OSTTS06115B and 0395033006 maintain full RoHS3 compliance, ensuring regulatory alignment for EU and equivalent markets.

Q: What is the significance of the torque specification difference?

A: The OSTTS06115B specifies 0.2 Nm (1.7 Lb-In) screw torque; the 0395033006 specifies 0.23 Nm (2.0 Lb-In). This minor variation reflects different termination mechanism designs. Follow the specific torque value for each part to ensure proper wire retention without over-tightening.
