OSTTH040160 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTH040160 is a 4-position terminal block plug manufactured by On Shore Technology Inc., designed for unshrouded headers with 0.197" (5.00mm) pitch spacing. This component is an active product with full RoHS3 compliance and REACH unaffected status. Terminal block plugs are essential interconnection components in industrial control systems, power distribution panels, and modular electronic assemblies where reliable screw-terminated connections are required. Substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application compatibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTH040160 is determined by the following critical parameters that must remain consistent:

• Connector Type: Plug for unshrouded header (mechanical and electrical interface compatibility)
• Number of Positions: 4 positions (circuit count requirement)
• Pitch Spacing: 0.197" (5.00mm) (physical alignment with mating header)
• Termination Style: Screw (connection method and tooling compatibility)
• Mounting Configuration: Free hanging (in-line) (installation method)
• Voltage Rating: 300 V UL (electrical safety threshold)
• Wire Gauge Compatibility: 14-22 AWG minimum support (conductor accommodation)
• Flammability Rating: UL94 V-0 (material safety requirement)
• Compliance Status: RoHS3 compliant, REACH unaffected (regulatory requirement)

The ED130/4DS qualifies as a direct substitute based on these core parameters. Variations in contact material, housing material, wire entry angle, and operating temperature range do not preclude substitution when the above critical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both OSTTH040160 and ED130/4DS are active products with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The OSTTH040160 supports a wider operating temperature range (-40°C to 115°C) and accommodates wire gauges from 0.34mm² to 1.5mm², providing greater flexibility for applications requiring extended temperature performance or smaller conductor sizes.

The ED130/4DS provides specified current rating (10 A UL), defined screw size (M2.6), and copper beryllium contact material, offering enhanced electrical performance characteristics and documented mechanical specifications suitable for applications requiring explicit current capacity verification.

Selection between these parts should be based on application-specific requirements: choose OSTTH040160 for extended temperature range or smaller wire gauge requirements; choose ED130/4DS when documented current rating and contact material specifications are required for design verification.

Frequently Asked Questions (FAQ)

Q: Can ED130/4DS replace OSTTH040160 in all applications?

A: ED130/4DS qualifies as a substitute when the application operates within the -30°C to 105°C temperature range and uses wire gauges of 1.5mm² or larger. Applications requiring operation below -30°C or above 105°C, or using wire gauges smaller than 0.34mm², require OSTTH040160.

Q: What is the difference in wire gauge accommodation?

A: OSTTH040160 accepts 0.34-1.5mm² (14-22 AWG). ED130/4DS specifies 1.5mm² maximum. Applications using conductors smaller than 0.34mm² require OSTTH040160.

Q: Are the screw torque specifications identical?

A: Yes. Both parts specify 0.4 Nm (4.6 Lb-In) screw torque, ensuring consistent installation procedures.

Q: What is the significance of the different contact materials?

A: OSTTH040160 uses brass contacts; ED130/4DS uses copper beryllium contacts. Copper beryllium provides enhanced electrical conductivity and contact reliability. Material selection does not affect mechanical compatibility or pitch alignment.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both OSTTH040160 and ED130/4DS are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial applications.

Q: What does the 90° wire entry specification mean for ED130/4DS?

A: The 90° wire entry angle indicates the wire termination approach relative to the connector body. This does not affect compatibility with the mating unshrouded header but may influence panel layout and installation geometry.

Q: Are inventory levels a consideration for substitution?

A: OSTTH040160 has 810 pieces in stock; ED130/4DS has 1093 pieces in stock. Availability may influence procurement decisions based on project timeline requirements.
