Phoenix Contact 1678583 Heavy Duty Connector Insert - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1678583 is a male insert connector without contacts for the HEAVYCON® M series. This component is designed for 4-position crimp termination applications with a 42V voltage rating and 10A current capacity. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance. Substitute parts must maintain compatibility with the HEAVYCON® M series ecosystem while meeting the electrical and mechanical requirements of the original application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1678583 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Series: HEAVYCON® M (ensures mechanical and electrical interface compatibility)
• Gender: Male (functional requirement for mating interface)
• Number of Positions: 4 (circuit configuration requirement)
• Termination Style: Crimp (assembly process compatibility)
• Contact Type: CK 1.6-ED (electrical and mechanical contact specification)
• Housing Material: Polycarbonate (PC) (environmental and mechanical properties)
• Material Flammability Rating: UL94 V-0 (safety compliance requirement)

Electrical Performance Parameters:

• Voltage Rating: Substitute must equal or exceed 42V
• Current Rating: Substitute must equal or exceed 10A

Environmental Parameters:

• Operating Temperature Range: Substitute must accommodate the -40°C to 125°C range or provide equivalent coverage
• Moisture Sensitivity Level: MSL 1 (Unlimited) compatibility

The Phoenix Contact 1636088 satisfies all mandatory compatibility criteria and electrical performance requirements, qualifying it as a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1636088 is the qualified substitute for the obsolete 1678583. Both components maintain identical mechanical and electrical interface specifications within the HEAVYCON® M series. The 1636088 provides enhanced voltage rating (50V versus 42V) and maintains equivalent current capacity (10A).

The primary operational difference is the maximum operating temperature: the 1636088 is rated to 85°C compared to the original 125°C specification. Applications requiring sustained operation above 85°C require thermal analysis to confirm compatibility. For applications operating within the 85°C thermal envelope, the 1636088 provides full functional equivalence.

The 1636088 holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The substitute is available in bulk packaging with 950 units in current inventory.

Frequently Asked Questions (FAQ)

Q: Can the 1636088 be used as a direct replacement for the 1678583?

A: Yes, within thermal operating parameters. Both components share identical mechanical interfaces, electrical contact specifications, and series compatibility. The 1636088 is suitable for applications operating at or below 85°C. Applications requiring the full -40°C to 125°C range of the original part require thermal verification.

Q: What is the difference between an Insert and a Module connector type?

A: The 1678583 is classified as an Insert without Contacts, while the 1636088 is a Module without Contacts. Both are compatible within the HEAVYCON® M series and maintain the same electrical and mechanical interface specifications for 4-position crimp termination.

Q: Does the higher voltage rating of the 1636088 affect compatibility?

A: No. The 50V rating of the 1636088 exceeds the 42V requirement of the original application, providing additional safety margin. Voltage rating compatibility is unidirectional: a higher-rated component is suitable for lower-voltage applications.

Q: Are there packaging differences between these parts?

A: The 1678583 was supplied with unspecified packaging. The 1636088 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to the substitute?

A: The 1636088 maintains UL94 V-0 flammability rating and achieves ROHS3 compliance. Both components are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
