Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1646528 is based on the following critical parameters that must align between the main part and substitute components:

Connector Category: Both parts must function within the Heavy Duty Connectors classification to ensure mechanical and electrical interface compatibility.

Manufacturer Consistency: Phoenix Contact maintains design and quality standards across its product lines. Substitute parts from the same manufacturer ensure compatibility with existing system architectures.

Size Designation: The B10 size specification is a critical mechanical parameter. Substitute parts must maintain the B10 form factor to ensure proper mating with corresponding connector interfaces.

Regulatory Compliance: RoHS compliance and ECCN/HTSUS classifications must be maintained to ensure the substitute part meets the same regulatory and trade requirements as the original component.

Environmental Ratings: Moisture sensitivity level (MSL 1) indicates unlimited moisture exposure capability. Substitute parts must maintain this environmental tolerance.

The identified substitute part 1412831 satisfies these substitution criteria through matching category classification, manufacturer origin, B10 size specification, and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412831 is the designated substitute for the obsolete 1646528 coupling housing. This substitution is supported by the following engineering factors:

Product Status Alignment: The 1412831 maintains active product status, ensuring continued manufacturer support, availability, and compliance with current manufacturing standards. The obsolete status of the 1646528 creates supply chain risk that the active substitute eliminates.

Regulatory Compliance Equivalence: Both parts maintain identical RoHS compliance status, ECCN classification (EAR99), and HTSUS coding (8538.90.8180), confirming that the substitute meets all regulatory requirements applicable to the original component.

Mechanical Compatibility: The B10 size specification is preserved in the substitute part, ensuring mechanical interface compatibility with existing connector systems designed for the original component.

Environmental Certification: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating, confirming equivalent environmental tolerance for industrial applications.

The 1412831 is specified as a base-mount connector with side entry configuration, M25 thread size, and IP66/IP67 ingress protection rating. These specifications define the substitute's functional characteristics within the HEAVYCON® EVO series.

Frequently Asked Questions (FAQ)

Q: Why is the 1646528 being replaced?

A: The 1646528 has reached obsolete product status. The 1412831 is the active equivalent that maintains the same connector category, size designation (B10), manufacturer origin, and regulatory compliance profile.

Q: Are the 1646528 and 1412831 mechanically interchangeable?

A: Both parts share the B10 size specification and are manufactured by Phoenix Contact within the heavy-duty connector category. The 1412831 is specified as a base-mount connector with side entry configuration and M25 thread size. Mechanical compatibility depends on the specific application interface requirements.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 1646528 and 1412831 are RoHS compliant, carry the same ECCN classification (EAR99), and share the identical HTSUS code (8538.90.8180).

Q: What is the environmental rating difference between these parts?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating. The 1412831 provides additional environmental specification with IP66/IP67 ingress protection rating and an operating temperature range of -40°C to 125°C.

Q: What packaging is available for the substitute part?

A: The 1412831 is available in bulk packaging configuration.

Q: Is the 1412831 part of the same connector series as the 1646528?

A: The 1412831 is specified within the HEAVYCON® EVO series. Both parts function within the Phoenix Contact heavy-duty connector product family.
