Phoenix Contact 1678619 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1678619 is a female insert connector without contacts, designed for the HEAVYCON® M heavy duty connector series. This 4-position crimp termination component operates at 42V with a 10A current rating and maintains functionality across -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new designs requiring compatible components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1678619 is determined by the following critical parameters:

Core Compatibility Requirements:

• Series: HEAVYCON® M
• Connector Type: Insert or Module without Contacts
• Gender: Female
• Number of Positions: 4
• Termination Style: Crimp
• Contact Type: CK 1.6-ED
• Housing Material: Polycarbonate (PC)
• Material Flammability Rating: UL94 V-0

Electrical Performance Criteria:

• Voltage Rating: Equal to or greater than 42V
• Current Rating: Equal to or greater than 10A

Environmental & Compliance Criteria:

• Operating Temperature Range: Must accommodate -40°C minimum; upper limit of 85°C or higher acceptable
• RoHS Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 1636091 meets all core compatibility requirements and electrical performance criteria. The primary distinction is the connector type classification (Module versus Insert) and enhanced voltage rating (50V versus 42V), both of which support functional equivalence within the HEAVYCON® M ecosystem.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1636091 is the qualified substitute for the obsolete 1678619 based on the following engineering criteria:

Product Status & Availability: Part 1636091 maintains active product status with 716 units in current inventory, ensuring supply chain continuity for applications previously dependent on the obsolete 1678619.

Electrical Equivalence: The substitute part exceeds the voltage specification of the original (50V versus 42V), providing enhanced electrical margin. Current rating remains equivalent at 10A.

Compliance & Certification: Both parts maintain UL94 V-0 flammability rating and polycarbonate housing construction. Part 1636091 carries ROHS3 compliance, representing current regulatory alignment. REACH unaffected status confirms material composition compliance.

Thermal Considerations: The substitute part operates to 85°C maximum, compared to the original 125°C upper limit. Applications requiring sustained operation above 85°C require thermal profile verification against actual system requirements.

Connector Architecture: The transition from Insert to Module classification within the HEAVYCON® M series maintains mechanical and electrical compatibility while providing updated design standards.

Frequently Asked Questions (FAQ)

Q: Can the 1636091 directly replace the 1678619 in existing assemblies?

A: Yes, within the HEAVYCON® M series framework. Both components share identical gender, position count, termination style, contact type, and housing material. Mechanical compatibility is maintained. Verify that application thermal requirements do not exceed 85°C continuous operation.

Q: What is the difference between Insert and Module connector types in this context?

A: Both are contact-less components within the HEAVYCON® M series. The Insert classification (1678619) and Module classification (1636091) represent different design generations within the same connector family. Both function as female receptacles for 4-position crimp terminations.

Q: Does the higher voltage rating of 1636091 affect compatibility?

A: No. The 50V rating of the substitute part exceeds the 42V requirement of the original, providing additional electrical margin. This represents an enhancement rather than a limitation.

Q: Are there packaging differences between these parts?

A: The 1678619 was supplied in standard packaging (not specified). The 1636091 is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to the substitute part?

A: The 1636091 carries ROHS3 compliance, UL94 V-0 flammability rating, and REACH unaffected status. These certifications align with current regulatory requirements for heavy duty connector applications.

Q: Is the operating temperature range difference significant?

A: The 1678619 operates to 125°C; the 1636091 to 85°C. For applications operating continuously above 85°C, thermal performance must be evaluated against actual system requirements. For standard industrial applications within -40°C to 85°C, the substitute is fully equivalent.
