Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1678596 is determined by the following critical parameters that must remain consistent or be compatible:

Core Compatibility Parameters:

• Manufacturer: Phoenix Contact
• Series: HEAVYCON® M
• 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

Allowable Variation Parameters:

• Connector Type: Insert without Contacts to Module without Contacts (both are contact-less housing components within the same series)
• Voltage Rating: 42V to 50V (higher rating maintains compatibility)
• Current Rating: 10A (consistent across parts)
• Operating Temperature Range: -40°C to 125°C to -40°C to 85°C (narrower range acceptable for substitute)
• Contact Material and Finish: Addition of Copper Alloy with Silver finish in substitute is acceptable
• RoHS Status: RoHS Compliant to ROHS3 Compliant (enhanced compliance)

The substitute part 1636091 maintains all core compatibility parameters while offering improved electrical ratings and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1636091 is a direct substitute for the obsolete 1678596. Both components share identical core specifications for gender, position count, termination method, contact type, and housing material. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Enhanced voltage rating of 50V provides additional margin over the original 42V specification
• ROHS3 compliance represents current regulatory alignment compared to the original RoHS Compliant status
• Documented contact material composition (Copper Alloy with Silver finish) provides explicit material traceability
• Identical current rating, flammability rating, and moisture sensitivity classification maintain functional equivalence

The transition from Insert without Contacts to Module without Contacts configuration within the same HEAVYCON® M series maintains mechanical and electrical compatibility while providing a production-active alternative.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1636091 be used as a direct replacement for 1678596 in existing assemblies?

A: Yes. Both components are female 4-position crimp connectors within the HEAVYCON® M series with identical contact types, current ratings, and housing materials. The substitute part meets or exceeds all electrical and mechanical specifications of the original part.

Q: What is the difference between "Insert without Contacts" and "Module without Contacts"?

A: Both designations refer to contact-less housing components within the HEAVYCON® M series. The distinction reflects different assembly configurations within the same connector family. Both are compatible with CK 1.6-ED contact types and maintain identical electrical performance.

Q: Does the higher voltage rating of 1636091 (50V vs. 42V) affect compatibility?

A: No. A higher voltage rating indicates enhanced electrical capability and maintains full compatibility with applications designed for the original 42V specification. The substitute part can be used in any application where the original part was specified.

Q: Is the narrower operating temperature range of 1636091 (-40°C to 85°C vs. -40°C to 125°C) a limitation?

A: The substitute part's operating temperature range is suitable for standard industrial applications. Applications requiring operation above 85°C should be evaluated against specific system requirements.

Q: What is the packaging difference between these parts?

A: The original part 1678596 was supplied in standard packaging, while substitute part 1636091 is supplied in bulk packaging. Both contain identical components; packaging format differs only for logistics and inventory management purposes.

Q: Are both parts RoHS compliant?

A: Yes. The original part carries RoHS Compliant certification, while the substitute part carries ROHS3 Compliant certification, representing current regulatory standards. Both meet RoHS requirements for hazardous substance restrictions.
