Phoenix Contact 1775745 Female Insert 8-Position Crimp Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1775745 is a female insert without contacts for the HEAVYCON® D8 heavy duty connector series, configured for 8-position crimp termination. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability. The part operates within a 50V/10A electrical envelope and maintains compliance with RoHS and UL94 V-0 flammability standards across the operating temperature range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1775745 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 & Gender: Female insert without contacts configuration must be maintained.
• Size Designation: D8 form factor is non-negotiable for physical fit.
• Termination Style: Crimp termination method must remain consistent.
• Electrical Ratings: Voltage (50V) and current (10A) ratings establish the maximum operational envelope.
• Contact Type: CK 1.6-ED contact specification ensures proper mating and electrical performance.
• Environmental Compliance: RoHS compliance and UL94 V-0 flammability rating must be preserved.
• Operating Temperature: -40°C to 125°C range must be supported.

The substitute part 1584363 qualifies as an equivalent based on these parameters, with the distinction that it includes an additional ground position (8+Ground) while maintaining all other critical specifications.

Engineering Selection Recommendations

The Phoenix Contact 1584363 is the designated substitute for the obsolete 1775745 based on the following engineering criteria:

Product Status & Supply Continuity: The 1775745 is classified as obsolete, creating supply risk. The 1584363 maintains active product status with confirmed inventory availability (1045 pcs), ensuring long-term procurement viability.

Compliance & Certification Alignment: Both parts maintain identical RoHS compliance and UL94 V-0 flammability certification, satisfying regulatory requirements without modification to existing designs.

Electrical & Mechanical Equivalence: All critical parameters—voltage rating (50V), current rating (10A), contact type (CK 1.6-ED), operating temperature range (-40°C to 125°C), and D8 form factor—are preserved, ensuring direct functional substitution.

Functional Enhancement: The 1584363 provides an additional ground position (8+Ground configuration) while maintaining the same electrical and mechanical envelope. This enhancement does not compromise compatibility with existing 8-position applications; the ground position is supplementary and does not interfere with standard 8-position wiring schemes.

Frequently Asked Questions (FAQ)

Q: Can the 1584363 directly replace the 1775745 in existing designs?

A: Yes. The 1584363 maintains all critical electrical and mechanical parameters of the 1775745. The additional ground position in the 1584363 does not prevent its use in applications designed for the standard 8-position configuration. The ground contact is independent and does not affect the operation of the primary 8 positions.

Q: What is the significance of the 8+Ground configuration in the 1584363?

A: The 1584363 includes a dedicated ground position in addition to the 8 standard signal positions. This provides enhanced grounding capability for applications requiring dedicated ground return paths. In applications using only the 8 standard positions, the ground contact remains unused without affecting performance.

Q: Are there any packaging differences between the two parts?

A: The 1775745 is supplied with unspecified packaging, while the 1584363 is supplied in bulk packaging. Both parts are identical in form factor and electrical characteristics; packaging differences do not affect component performance or interchangeability.

Q: Why is the 1775745 classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The 1584363 represents the active continuation of this product line, offering equivalent functionality with the addition of a ground position option.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1775745 and 1584363 are RoHS compliant and maintain UL94 V-0 flammability certification, satisfying environmental and safety regulatory requirements.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to 125°C, ensuring thermal compatibility across industrial and commercial applications.
