Phoenix Contact 1503108 Sensor Actuator Box - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1503108 is a sensor actuator box designed for use with circular connectors in industrial sensing and transduction applications. This component features a dust-tight, waterproof enclosure with six connector openings and is constructed from polyamide material. The 1503108 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1516629 qualifies as a direct substitute for the 1503108 based on the following alignment of critical parameters:

• Functional Equivalence: Both parts serve as sensor actuator boxes with identical connector opening configuration (6 openings)
• Environmental Protection: Both maintain dust-tight and waterproof specifications
• Color Consistency: Both are green, supporting visual identification and system standardization
• Regulatory Compliance: Both are RoHS compliant with identical MSL rating (1 - Unlimited)
• Application Compatibility: Both are designated for use with circular connectors in sensor and transducer applications
• Manufacturer Continuity: Both are Phoenix Contact products, ensuring design and quality consistency

The primary material difference (polyamide versus polybutylene terephthalate) and the addition of shell size specification (M12) in the substitute part represent engineering refinements rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

The 1516629 is the designated substitute for the obsolete 1503108. Selection of the 1516629 is supported by:

• Product Status: The 1516629 maintains active product status, ensuring continued availability and manufacturer support
• Regulatory Alignment: Both parts maintain identical RoHS compliance and MSL ratings, eliminating regulatory substitution barriers
• Functional Parity: Connector opening count, environmental protection ratings, and application scope remain unchanged
• Material Specification: The PBT material in the 1516629 provides equivalent or enhanced performance characteristics compared to polyamide in industrial sensor and transducer applications
• Standardization: M12 shell size specification in the 1516629 provides dimensional clarity for integration planning

Frequently Asked Questions (FAQ)

Q: Can the 1516629 directly replace the 1503108 in existing installations?

A: Yes. Both parts share identical connector opening configuration, environmental protection specifications, and regulatory compliance status. The 1516629 is the active product continuation of the obsolete 1503108 line.

Q: What is the significance of the material change from polyamide to PBT?

A: Polybutylene terephthalate (PBT) is a high-performance engineering plastic commonly used in industrial sensor enclosures. The material change represents a product refinement rather than a functional limitation. Both materials meet the dust-tight and waterproof requirements specified for this product category.

Q: Does the M12 shell size specification on the 1516629 affect compatibility?

A: The M12 specification on the 1516629 provides explicit dimensional standardization for the connector interface. This clarification supports integration planning and does not restrict compatibility with existing circular connector applications.

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

A: No. Both the 1503108 and 1516629 maintain identical RoHS compliance status and MSL ratings (1 - Unlimited), eliminating compliance-related substitution concerns.

Q: What packaging options are available for the 1516629?

A: The 1516629 is supplied in bulk packaging, suitable for production and integration workflows.
