Phoenix Contact 1605773 Circular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1605773 is a 6-position circular connector receptacle housing designed for male pins in a free-hanging (in-line) configuration. This component features a threaded fastening mechanism, shielded design, and M40-6 shell size with mixed contact sizes (2.0mm and 3.6mm power contacts). The part is classified as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this connector specification.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1605773 is determined by strict equivalence across the following critical parameters:

Connector Type & Configuration: Receptacle housing for male pins, 6-position arrangement (2 + 3 Power + PE)
Shell Size & Insert: M40-6 specification
Contact Specifications: Crimp contact type with 2.0mm (2 positions) and 3.6mm power (4 positions) sizing
Mounting & Orientation: Free-hanging (in-line) configuration with normal orientation
Environmental & Compliance: IP67 ingress protection, shielded design, RoHS compliance, operating temperature range -40°C to 125°C

The substitute part Phoenix Contact 1613426 maintains equivalence across all critical parameters. The primary difference is the fastening mechanism (Push-Twist versus Threaded), which represents a functional variation within the same connector family while preserving electrical and mechanical compatibility for the specified application requirements.

Engineering Selection Recommendations

The Phoenix Contact 1613426 is the manufacturer-recommended substitute for the 1605773. Both components maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, shell size, contact sizing, environmental protection rating, and compliance certifications.

The 1605773 carries Last Time Buy status, indicating end-of-life production. The 1613426 maintains Active product status with higher current inventory availability (894 pcs versus 723 pcs), ensuring sustained supply chain access for ongoing production requirements.

Both parts are RoHS compliant and rated for identical operating temperature ranges (-40°C to 125°C) with MSL 1 classification. The fastening mechanism difference (Push-Twist versus Threaded) represents a functional variation that does not affect electrical performance or mechanical compatibility within the SM series connector family.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 1605773 and 1613426?

A: The fastening mechanism differs. The 1605773 uses threaded fastening, while the 1613426 uses push-twist fastening. All other electrical and mechanical specifications remain identical.

Q: Are these parts electrically interchangeable?

A: Yes. Both parts maintain the same 6-position configuration, contact sizing (2.0mm and 3.6mm), shell size (M40-6), and shielded design. Electrical performance is equivalent.

Q: Why is the 1605773 marked as Last Time Buy?

A: Last Time Buy status indicates Phoenix Contact has discontinued production of this part number. The 1613426 is the active replacement within the SM series.

Q: Do both parts support the same operating temperature range?

A: Yes. Both parts operate across -40°C to 125°C and maintain IP67 ingress protection in this range.

Q: Are there any compliance differences between these parts?

A: No. Both parts are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN/HTSUS coding.

Q: What is the impact of the fastening type change?

A: The fastening mechanism change from threaded to push-twist affects only the connection method to the mating connector. This does not impact electrical performance or mechanical fit within the M40-6 shell size specification.

Q: Are contacts included with either part?

A: No. Both parts are supplied as housings only. Contacts must be sourced separately and crimped according to Phoenix Contact specifications.
