OSTH412705B Terminal Block Plug Equivalent & Substitute Parts

Part Overview

The OSTH412705B is a 12-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 0.197" (5.00mm) pitch spacing and 270° wire entry orientation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates within a temperature range of -30°C to 105°C and supports wire gauges from 12-26 AWG with push-in spring termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTH412705B is determined by the following critical parameters:

• Position Count & Pitch: 12 positions at 0.197" (5.00mm) spacing (non-negotiable for mechanical and electrical compatibility)
• Connector Type: Plug with female sockets (required for mating with corresponding receptacles)
• Termination Method: Screwless push-in spring termination (ensures compatibility with existing wire preparation and installation procedures)
• Mounting Configuration: Free hanging (in-line) orientation
• Electrical Ratings: Minimum 300 V UL rating and support for 12-26 AWG wire gauge
• Flammability & Compliance: UL94 V-0 material rating and ROHS3 compliance

The Phoenix Contact 1910458 qualifies as a substitute based on matching these core parameters. While the wire entry angle differs (180° versus 270°), this represents a geometric variation that does not affect electrical or mechanical substitutability when the connector is properly oriented within the assembly.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910458 is the qualified substitute for the obsolete OSTH412705B. Selection of this alternative is supported by:

• Compliance Alignment: Both components maintain ROHS3 compliance and UL94 V-0 flammability ratings, ensuring regulatory continuity in applications subject to environmental and safety standards.
• Active Product Status: The 1910458 is classified as active, providing assured long-term availability and supply chain stability compared to the obsolete OSTH412705B.
• Electrical & Mechanical Equivalence: Matching voltage ratings (300 V UL), wire gauge support (12-26 AWG), and termination methodology (push-in spring) ensure functional interchangeability within existing circuit designs.
• Inventory Availability: Both components are currently in stock, enabling immediate procurement without lead-time constraints.

The primary design consideration is the wire entry angle difference (180° versus 270°). This geometric variation requires assessment of the physical installation space and wire routing within the target assembly to confirm compatibility with existing mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1910458 directly replace the OSTH412705B without design modifications?

A: The 1910458 provides electrical and mechanical substitutability based on matching position count, pitch, termination style, and voltage ratings. The 180° wire entry angle differs from the original 270° orientation; physical installation space must be evaluated to confirm the connector orientation is compatible with the assembly layout.

Q: Are there differences in wire preparation or installation procedures between these parts?

A: Both components use identical screwless push-in spring termination. Wire gauge compatibility (12-26 AWG) and strip length requirements are equivalent, allowing the same installation methodology.

Q: What is the significance of the wire entry angle difference?

A: Wire entry angle defines the direction from which conductors approach the connector. A 180° entry is straight-in, while 270° is angled. This affects physical routing and space requirements but does not impact electrical performance or mating compatibility with corresponding receptacles.

Q: Does the substitute part maintain the same compliance certifications?

A: Yes. Both the OSTH412705B and 1910458 are ROHS3 compliant and carry UL94 V-0 material flammability ratings. Regulatory requirements for these certifications are satisfied by the substitute.

Q: Why is the OSTH412705B classified as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The Phoenix Contact 1910458, classified as active, represents the current market equivalent and ensures ongoing availability for replacement and new applications.
