Phoenix Contact 1687503 Heavy Duty Connector Insert - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1687503 is a male insert without contacts for heavy duty connectors, configured for 46 positions with crimp termination. This component is part of the HEAVYCON® BB 46 series and is currently classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for maintaining system compatibility and ensuring continued availability for repair, replacement, and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Phoenix Contact 1687503 is determined by strict alignment of the following critical parameters:

• Series Compatibility: Both parts must belong to the HEAVYCON® BB 46 series
• Connector Type: Insert without contacts configuration
• Gender: Male orientation
• Size Designation: B24 form factor
• Termination Method: Crimp termination style
• Electrical Ratings: Voltage (500V) and current (16A) capacity
• Contact Type: CK 2.5-ED specification
• Environmental Specifications: Operating temperature range (-40°C to 125°C), flammability rating (UL94 V-0), and moisture sensitivity level (MSL 1)

The substitute part 1584761 maintains compatibility across all these parameters while introducing a configuration variation: 46+Ground position count. This additional ground position does not compromise substitution eligibility, as it represents an enhanced variant within the same electrical and mechanical framework.

Engineering Selection Recommendations

The Phoenix Contact 1584761 is the designated substitute for the obsolete 1687503. Selection of this substitute is supported by the following engineering criteria:

Product Status Alignment: The 1584761 maintains active product status, ensuring ongoing availability, technical support, and supply chain continuity. The 1687503, classified as obsolete, presents supply and support limitations.

Regulatory Compliance: Both parts maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The 1584761 carries ROHS3 compliance, representing current regulatory standards, while the 1687503 carries RoHS compliance. This upgrade in compliance status supports long-term regulatory adherence.

Electrical and Mechanical Equivalence: The 1584761 preserves all critical electrical parameters (500V voltage rating, 16A current rating, CK 2.5-ED contact type) and mechanical specifications (B24 size, crimp termination, polycarbonate housing, -40°C to 125°C operating range).

Configuration Enhancement: The addition of a ground position (46+Ground versus 46) in the 1584761 represents a functional enhancement that does not compromise backward compatibility within the HEAVYCON® BB 46 series framework.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1584761 directly replace the 1687503 in existing assemblies?

A: Yes. The 1584761 maintains identical electrical ratings (500V, 16A), mechanical form factor (B24 size), termination method (crimp), contact specification (CK 2.5-ED), and environmental operating range (-40°C to 125°C). Both are male inserts without contacts within the HEAVYCON® BB 46 series.

Q: What is the significance of the 46+Ground position configuration in the 1584761?

A: The additional ground position provides enhanced grounding capability within the same physical and electrical framework. This does not alter the core substitution compatibility; it represents a functional variant of the same connector family.

Q: Why is the 1687503 classified as obsolete?

A: Obsolescence indicates that the part is no longer in active production. The 1584761 serves as the active equivalent, ensuring continued availability and manufacturer support.

Q: Are there packaging differences between these parts?

A: The 1687503 is listed with unspecified packaging, while the 1584761 is supplied in bulk packaging. Both maintain identical electrical and mechanical specifications.

Q: Do both parts meet current regulatory standards?

A: Both parts maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The 1584761 carries ROHS3 compliance, representing current regulatory requirements.
