OSTTO110152 Equivalent & Substitute Parts

Part Overview

The OSTTO110152 is an 11-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with side entry configuration. This component operates at 300 V and 10 A, accommodating wire gauges from 16-26 AWG with screw-based rising cage clamp termination. The part is currently active in production and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable wire-to-board connections.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter ranges, allowing for design flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1729212 qualifies as a substitute based on the following alignment of critical parameters:

• Both components maintain 11 positions per level with side entry interlocking configuration
• Electrical ratings are equivalent: 10 A current and 300 V voltage across both parts
• Pitch specifications are within acceptable tolerance (0.197" vs 0.200"), supporting PCB layout compatibility
• Wire gauge acceptance ranges overlap (16-26 AWG vs 14-30 AWG), with the substitute accommodating a broader range
• Both utilize screw-based rising cage clamp termination with through-hole mounting
• Horizontal with board mating orientation is maintained
• Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating

The primary design consideration for substitution is pitch tolerance and wire gauge compatibility within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTO110152 and 1729212 maintain active product status with full ROHS3 compliance and EAR99 export classification. Selection between these components should be based on:

• PCB layout tolerance requirements relative to the 0.03" (0.08mm) pitch difference
• Wire gauge requirements within the specified ranges
• Screw torque specifications (OSTTO110152: 0.4 Nm vs 1729212: 0.5-0.6 Nm)
• Supplier availability and lead time considerations
• Design validation requirements for the specific application

Both parts satisfy the core electrical and mechanical requirements for 11-position, 300 V, 10 A wire-to-board terminal block applications with side entry configuration.

Frequently Asked Questions (FAQ)

Q: Can the 1729212 be used as a direct replacement for OSTTO110152 in existing designs?

A: The 1729212 qualifies as a substitute based on equivalent electrical ratings, matching position count, and compatible termination method. However, the 0.03" pitch difference requires PCB layout verification to confirm hole spacing compatibility.

Q: What is the significance of the wire gauge range difference?

A: The OSTTO110152 accepts 16-26 AWG, while the 1729212 accepts 14-30 AWG. The substitute part accommodates a broader wire gauge range, making it suitable for applications using either specification.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) ratings and EAR99 export classification. The OSTTO110152 is REACH Unaffected, while the 1729212 is REACH Affected. Verify REACH compliance requirements for your specific application.

Q: How do the screw torque specifications differ?

A: The OSTTO110152 specifies 0.4 Nm (4.6 Lb-In) with M2.5 screw thread, while the 1729212 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In) with M3 screw thread. Assembly procedures should follow the respective manufacturer specifications.

Q: What packaging considerations apply to these parts?

A: Both components are supplied in bulk packaging. Verify minimum order quantities and lead times with your supplier, as availability may differ between manufacturers.
