OSTTS22715B Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS22715B is a 22-position terminal block plug manufactured by On Shore Technology Inc., designed for free-hanging (in-line) applications with female sockets and 5.00mm pitch spacing. This component is actively produced and widely used in industrial control, automation, and power distribution systems requiring screw-type termination with UL94 V-0 flammability rating.

Substitute parts become necessary when the primary component faces supply constraints, extended lead times, or when system design requirements allow for compatible alternatives that meet or exceed the original specifications.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1792951 qualifies as a direct substitute based on the following critical parameters:

• Position Count: Both parts feature 22 positions, maintaining identical connector density
• Pitch Compatibility: 0.197" (5.00mm) vs. 0.200" (5.08mm) represents a 0.03mm variance, within acceptable mechanical tolerance for free-hanging applications
• Connector Type: Both are plug-type connectors with female sockets
• Mounting Configuration: Both are free-hanging (in-line) designs
• Termination Method: Both utilize screw-based termination
• Voltage Rating: Both meet or exceed 300V UL requirement
• Flammability Compliance: Both achieve UL94 V-0 rating
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected

The 1792951 provides enhanced specifications including higher current capacity (15A UL vs. unspecified for OSTTS22715B), expanded wire gauge compatibility (12-30 AWG), and improved termination technology (Rising Cage Clamp).

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTS22715B and 1792951 are active production components with full ROHS3 compliance and UL94 V-0 flammability certification, making either suitable for regulated industrial applications.

The OSTTS22715B remains the preferred choice when exact pitch specification (5.00mm) is a design constraint or when inventory availability is confirmed.

The 1792951 serves as a functional equivalent when supply of the primary part is unavailable. The 0.03mm pitch variance is mechanically acceptable for free-hanging connector applications. The Phoenix Contact part offers additional benefits including Rising Cage Clamp termination technology, expanded wire gauge acceptance (12-30 AWG), and specified current rating (15A UL), providing enhanced performance margins in applications where these parameters are relevant.

Frequently Asked Questions (FAQ)

Q: What is the pitch difference between OSTTS22715B and 1792951, and does it affect compatibility?

A: The OSTTS22715B has a 5.00mm pitch while the 1792951 has a 5.08mm pitch, a difference of 0.03mm. For free-hanging (in-line) connector applications, this variance falls within acceptable mechanical tolerance and does not prevent functional substitution.

Q: Are both parts suitable for the same voltage and current applications?

A: Both parts are rated for 300V UL. The 1792951 specifies 15A UL current capacity, while the OSTTS22715B does not provide a current specification. Applications requiring specified current ratings should reference the 1792951 documentation.

Q: Can the 1792951 accept the same wire gauge range as the OSTTS22715B?

A: The 1792951 accepts 12-30 AWG (0.2-2.5mm²), which encompasses the OSTTS22715B range of 12-24 AWG (0.34-2.5mm²). The 1792951 provides broader compatibility with smaller gauge conductors.

Q: What is the difference between standard screw termination and Rising Cage Clamp termination?

A: Rising Cage Clamp is an advanced screw termination technology that provides improved contact pressure and retention characteristics. Both termination methods are screw-based and suitable for industrial applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both the OSTTS22715B and 1792951 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial component use.
