Phoenix Contact 1775758 Heavy Duty Connector Insert - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1775758 is a male insert without contacts for the HEAVYCON® D8 heavy duty connector series, configured for 8 positions with crimp termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates within a 50V/10A electrical envelope and maintains performance across -40°C to 125°C operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1775758 is determined by strict alignment across the following critical parameters:

• Series Compatibility: Both parts must belong to the HEAVYCON® D8 series to ensure mechanical and electrical interchangeability within the connector ecosystem
• Connector Type: Insert without contacts configuration must be maintained
• Gender: Male insert designation
• Size: D8 form factor
• Termination Style: Crimp termination method
• Electrical Ratings: Voltage (50V) and current (10A) ratings must be equal or exceed the original specification
• Contact Type: CK 1.6-ED contact specification
• Operating Temperature: -40°C to 125°C range must be supported
• Housing Material: Polyamide (PA), Nylon composition
• Flammability Rating: UL94 V-0 compliance

The substitute part 1584350 meets all these criteria. The primary functional difference is the addition of a ground position (8+Ground configuration), which represents an enhancement rather than a deviation from the core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1584350 substitute part is qualified for direct replacement of the 1775758 based on the following engineering criteria:

Product Status Alignment: The 1584350 maintains active product status within the Phoenix Contact catalog, ensuring continued availability, technical support, and supply chain stability. The 1775758 obsolete status necessitates transition to an active equivalent.

Regulatory Compliance: Both parts maintain UL94 V-0 flammability certification and RoHS compliance. The 1584350 carries ROHS3 compliance designation, representing current regulatory alignment. Both parts are classified as REACH Unaffected, confirming environmental compliance across applicable jurisdictions.

Electrical and Mechanical Equivalence: The 1584350 preserves all critical electrical parameters (50V/10A ratings), contact specifications (CK 1.6-ED), operating temperature range (-40°C to 125°C), and mechanical form factor (D8 size, crimp termination). The addition of a ground position in the 1584350 configuration does not compromise compatibility with applications requiring the standard 8-position insert; the ground position represents functional enhancement.

Material and Construction: Identical housing material (Polyamide/Nylon) and flammability rating ensure thermal and mechanical performance parity across operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 1584350 directly replace the 1775758 in existing assemblies?

A: Yes. Both parts share identical electrical ratings (50V/10A), contact type (CK 1.6-ED), operating temperature range (-40°C to 125°C), and D8 form factor. The 1584350 is mechanically and electrically compatible with existing HEAVYCON® D8 connector housings and mating components.

Q: What is the functional difference between the 8-position and 8+Ground configurations?

A: The 1584350 includes a dedicated ground position in addition to the eight standard signal positions. This configuration does not affect compatibility with applications using only the eight standard positions; the ground position remains available for optional use.

Q: Are there packaging differences between these parts?

A: The 1775758 is listed with unspecified packaging, while the 1584350 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: Why is the 1775758 classified as obsolete?

A: Obsolescence reflects Phoenix Contact's product lifecycle management. The 1584350 represents the current active equivalent within the HEAVYCON® D8 series, offering enhanced functionality with ground position integration while maintaining full backward compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The 1775758 carries RoHS Compliant status, while the 1584350 carries ROHS3 Compliant status, reflecting current regulatory standards. Both parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special moisture control requirements.
