OSTT7200151 Equivalent & Substitute Parts

Part Overview

The OSTT7200151 is a 20-position wire-to-board terminal block manufactured by On Shore Technology Inc., featuring a 45° angle orientation with 0.250" (6.35mm) pitch and through-hole mounting. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The terminal block is designed for applications requiring secure wire termination with screw-based cage clamp technology and supports currents up to 30 A at 300 V.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTT7200151 is determined by the following critical parameters:

• Position Count: 20 positions per level (fixed requirement)
• Mating Orientation: 45° (135°) angle with board (fixed requirement)
• Mounting Type: Through-hole PCB mounting (fixed requirement)
• Voltage Rating: Minimum 300 V (equal or higher acceptable)
• Current Rating: Minimum 30 A (equal or higher acceptable)
• Wire Gauge Compatibility: Overlap with 10-24 AWG range
• Termination Method: Screw-based wire termination (fixed requirement)
• Compliance: ROHS3 compliance required

The substitute part KZ2070510000G from Amphenol Anytek meets the core functional requirements of position count, orientation, mounting type, and termination method. However, critical parameter deviations exist in pitch (5.00mm vs. 6.35mm), current rating (15 A vs. 30 A), and wire gauge range (12-26 AWG vs. 10-24 AWG), which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The KZ2070510000G substitute part is suitable for applications where the following conditions are met:

• Circuit current requirements do not exceed 15 A (the substitute's maximum rating)
• PCB layout can accommodate the reduced 5.00mm pitch spacing
• Wire gauges fall within the 12-26 AWG range
• Operating temperature range of -40°C ~ 115°C is acceptable

The substitute part's active product status and ROHS3 compliance provide advantages for long-term supply chain continuity compared to the obsolete OSTT7200151. Both parts maintain identical voltage ratings (300 V) and moisture sensitivity levels (MSL 1).

Applications requiring the full 30 A current capacity of the original part cannot use this substitute without circuit redesign or parallel connection configurations.

Frequently Asked Questions (FAQ)

Q: Can KZ2070510000G directly replace OSTT7200151 in existing designs?

A: Direct replacement is not possible due to pitch mismatch (5.00mm vs. 6.35mm). PCB layout modifications are required. Additionally, the 15 A current rating of the substitute is half that of the original part.

Q: What is the primary limitation of the KZ2070510000G substitute?

A: The current rating is reduced from 30 A to 15 A. Applications exceeding 15 A cannot use this substitute without circuit modification.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both OSTT7200151 and KZ2070510000G are ROHS3 compliant and REACH unaffected, with MSL 1 (unlimited moisture sensitivity level).

Q: How do the wire termination methods differ?

A: The original part uses a rising cage clamp mechanism, while the substitute employs a leaf spring with wire guard. Both are screw-based termination systems.

Q: Is the substitute part's wider operating temperature range (-40°C ~ 115°C) a compatibility factor?

A: The substitute's extended temperature range is a superset of the original part's range (-30°C ~ 105°C), providing no compatibility restriction for applications within the original temperature specification.

Q: What pitch consideration is critical for PCB redesign?

A: The substitute requires 5.00mm center-to-center spacing between positions, compared to 6.35mm for the original. This results in a more compact footprint and necessitates PCB layout recalculation.
