Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1605771 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle housing for male pins with identical 6-position arrangement (2 + 3 Power + PE)
• Shell Size & Insert Designation: M40-6 shell size ensures mechanical and electrical compatibility
• Contact Specifications: Matching contact sizes (2.0mm and 3.6mm Power) and crimp contact type
• Mounting & Orientation: Free-hanging, in-line configuration with normal orientation
• Environmental Rating: IP67 ingress protection and operating temperature range (-40°C ~ 125°C)
• Material & Compliance: Gadolinium-zinc shell material, polyamide insert, RoHS compliance, and shielded design

The substitute part Phoenix Contact 1613426 meets all these criteria, with the primary difference being the fastening mechanism (Push-Twist versus Threaded) and product status transition from Last Time Buy to Active.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1613426 is the designated manufacturer-recommended substitute for the 1605771. Both parts maintain identical electrical and mechanical specifications across all critical parameters, including connector configuration, shell size, contact specifications, and environmental ratings.

The transition from Last Time Buy status (1605771) to Active status (1613426) indicates manufacturer support continuity. The fastening mechanism change from Threaded to Push-Twist represents the primary design evolution in the substitute part. Both parts carry RoHS compliance certification and equivalent moisture sensitivity levels, supporting regulatory and environmental requirements.

Current inventory availability favors the substitute part (894 pcs versus 801 pcs for the main part), providing supply chain advantages for new designs and replenishment scenarios.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1613426 directly replace 1605771 in existing applications?

A: Yes, the 1613426 is electrically and mechanically equivalent across all specified parameters. The fastening mechanism differs (Push-Twist versus Threaded), which may require assembly procedure adjustment but does not affect electrical performance or environmental ratings.

Q: Are the contact specifications identical between these parts?

A: Yes. Both parts feature identical contact configurations: 2.0mm contacts (quantity 2) and 3.6mm power contacts (quantity 4), with matching crimp contact type and M40-6 shell size designation.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are rated IP67 for ingress protection, operate across -40°C to 125°C, carry RoHS compliance certification, and feature shielded, gadolinium-zinc shell construction with polyamide inserts.

Q: Why is the main part listed as Last Time Buy?

A: Last Time Buy status indicates Phoenix Contact has discontinued production of the 1605771. The 1613426 represents the active production equivalent, ensuring continued availability and manufacturer support.

Q: Are contacts included with either part?

A: No. Both the 1605771 and 1613426 are supplied as housings without contacts. Contacts must be sourced separately and crimped according to Phoenix Contact specifications.
