OSTTS24715A Equivalent & Substitute Parts

Part Overview

The OSTTS24715A is a 24-position terminal block plug manufactured by On Shore Technology Inc., featuring female sockets with 5.00mm pitch spacing and screw termination. This component is designed for free-hanging (in-line) applications requiring secure wire connections in the 12-24 AWG range. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial control and distribution applications.

Substitute parts become necessary when specific wire entry orientations, enhanced current ratings, or alternative termination mechanisms are required for system integration, or when inventory constraints necessitate equivalent alternatives from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS24715A is determined by the following critical parameters:

• Position Count & Pitch: Both substitute parts maintain 24 positions with 5.08mm pitch, providing mechanical and electrical compatibility within standard tolerance ranges for terminal block mating.
• Socket Type & Mounting: All parts feature female sockets in free-hanging configuration, ensuring identical mounting and connection methodology.
• Voltage & Temperature Ratings: Substitute parts meet or exceed the 300V UL requirement and maintain equivalent operating temperature ranges.
• Flammability & Compliance: All parts carry UL94 V-0 rating and RoHS3/REACH compliance, satisfying regulatory requirements.
• Wire Gauge Compatibility: Substitute parts accept 12-30 AWG (0.2-2.5mm²), encompassing the original 12-24 AWG specification.

The primary differentiators between substitutes are wire entry orientation (90° versus 270°) and termination mechanism (rising cage clamp versus standard screw), which do not affect electrical performance but influence physical installation geometry.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with full regulatory compliance. Selection between the OSTTS24715A and its substitutes depends on installation geometry requirements:

OSTTS24715A remains the primary choice when the original wire entry orientation and standard screw termination are specified in system design documentation.

1792469 (Phoenix Contact COMBICON MVSTBR) serves as a direct substitute when 90° wire entry orientation is required. The rising cage clamp termination provides enhanced wire retention compared to standard screw mechanisms. This part accommodates extended wire gauge range (12-30 AWG) and carries identical voltage and flammability ratings.

1792977 (Phoenix Contact COMBICON MVSTBW) functions as an alternative when 270° wire entry orientation is necessary for spatial constraints or panel layout requirements. Like 1792469, it features rising cage clamp termination and extended wire gauge compatibility. RoHS compliance is maintained across all regulatory frameworks.

The 5.08mm pitch of Phoenix Contact substitutes represents a 0.03mm deviation from the original 5.00mm specification, which falls within standard mechanical tolerance for terminal block mating interfaces and does not compromise electrical performance or physical fit.

Frequently Asked Questions (FAQ)

Q: Can 1792469 or 1792977 be used as direct drop-in replacements for OSTTS24715A?

A: Both Phoenix Contact parts are mechanically and electrically compatible. The 5.08mm pitch differs minimally from the 5.00mm original specification and remains within acceptable tolerance for mating with standard terminal block headers. Wire entry orientation differs (90° or 270° versus unspecified), which may require panel layout adjustment but does not affect electrical function.

Q: What is the difference between 1792469 and 1792977?

A: Both parts are identical except for wire entry orientation. 1792469 features 90° wire entry, while 1792977 features 270° wire entry. Selection depends solely on physical installation requirements and available space for wire routing.

Q: Do the Phoenix Contact substitutes support the same wire gauge range as the original?

A: The Phoenix Contact parts accept 12-30 AWG, which encompasses and exceeds the original 12-24 AWG specification. All wires within the original range are fully supported.

Q: Are there voltage or current rating differences?

A: The OSTTS24715A specifies 300V UL voltage with no stated current rating. Both Phoenix Contact substitutes maintain 300V UL voltage and add a 15A UL current rating. This represents equivalent or enhanced electrical capability.

Q: What is the significance of the rising cage clamp termination in the Phoenix Contact parts?

A: Rising cage clamp termination provides mechanical wire retention during insertion and removal, reducing the risk of accidental wire displacement. This differs from standard screw termination but does not affect electrical performance or compatibility with mating connectors.

Q: Are all parts RoHS compliant?

A: Yes. OSTTS24715A and 1792469 carry ROHS3 compliance. 1792977 carries RoHS compliance. All parts meet current regulatory requirements for hazardous substance restrictions.
