Phoenix Contact 1679537 Heavy Duty Connector Insert - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1679537 is a female insert without contacts for the HEAVYCON® D40 series heavy duty connector system. This component is designed for 40-position plus ground crimp termination applications with a voltage rating of 250V and current capacity of 10A. The part is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations. The 1679537 remains available in inventory (1026 pcs), but active alternatives should be evaluated for long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1584428 qualifies as a direct substitute for the 1679537 based on the following critical parameters that determine functional interchangeability:

• Series Compatibility: Both components belong to the HEAVYCON® D40 series
• Connector Type: Both are female inserts without contacts
• Position Configuration: Both support 40-position plus ground arrangement
• Size Designation: Both use B16 size specification
• Termination Method: Both employ crimp termination style
• Electrical Ratings: Both maintain 250V voltage rating and 10A current capacity
• Operating Temperature: Both function across -40°C to 125°C range
• Flammability Compliance: Both meet UL94 V-0 standard
• Moisture Sensitivity: Both rated at MSL 1 (Unlimited)

The primary distinction between these components lies in housing material composition and contact type specification, which do not affect the core substitution criteria for this connector insert category.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1584428 is the designated substitute for the obsolete 1679537 model. Both components maintain identical electrical specifications, mechanical dimensions, and performance ratings across all critical parameters. The 1584428 carries active product status with ROHS3 compliance certification, providing superior long-term supply chain availability compared to the obsolete 1679537.

The housing material difference (polycarbonate versus polyamide) and contact type variation do not affect the functional substitution criteria for this connector insert category, as both materials meet the same flammability standard and operating temperature requirements. Selection between these components should be based on current inventory requirements and future supply chain planning, with the 1584428 recommended for new designs and ongoing procurement due to its active status.

Frequently Asked Questions (FAQ)

Q: Can the 1584428 directly replace the 1679537 in existing applications?

A: Yes. Both components share identical electrical ratings (250V, 10A), mechanical dimensions (B16 size, 40+Ground positions), and operating temperature range (-40°C to 125°C). The connector insert will function identically within the HEAVYCON® D40 system.

Q: What is the significance of the housing material difference between these parts?

A: The 1679537 uses polycarbonate (PC) housing while the 1584428 uses polyamide (PA) nylon. Both materials achieve UL94 V-0 flammability rating and support the full operating temperature range. This difference does not affect electrical or mechanical compatibility.

Q: Why is the 1679537 listed as obsolete?

A: Product obsolescence indicates that Phoenix Contact has discontinued active manufacturing and support for this component. The 1584428 represents the current active equivalent within the HEAVYCON® D40 series.

Q: Are there packaging differences between these components?

A: The 1679537 is supplied without specified packaging designation, while the 1584428 is packaged in bulk format. Both are available as new original stock from current inventory.

Q: Do both parts meet current regulatory compliance standards?

A: The 1679537 carries RoHS Compliant certification. The 1584428 carries ROHS3 Compliant certification, representing the current regulatory standard. Both meet UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What contact type specifications apply to each component?

A: The 1679537 uses CK 1.6-BR and ER contact types, while the 1584428 uses CK 1.6-ED contact type. Both are compatible with the HEAVYCON® D40 series crimp termination system.
