Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1605798 is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle housing for male pins
• Position count and configuration: 6 positions (2 + 3 Power + PE)
• Shell size: M40-6
• Contact sizes: 2.0mm (2 positions), 3.6mm (4 positions)
• Mounting configuration: Panel mount, right angle
• Fastening method: Threaded
• Shell material: Metal
• Shielding: Shielded construction
• Operating temperature: -40°C to 125°C
• RoHS compliance: Required

The substitute part 1620663 meets all mandatory parameters. The primary distinction is product status: 1605798 is Last Time Buy (discontinued), while 1620663 is Active (current production). Additionally, 1620663 specifies IP67 ingress protection rating, providing enhanced environmental sealing compared to the original part.

Parameter Comparison

Engineering Selection Recommendations

1605798 to 1620663 Substitution:

The Phoenix Contact 1620663 is a direct functional substitute for 1605798. Both components share identical electrical and mechanical specifications within the SM series, including connector type, position configuration, shell size, contact sizing, mounting orientation, and operating parameters.

The transition from 1605798 (Last Time Buy) to 1620663 (Active) is supported by:

• Continuous production availability of 1620663
• Identical RoHS compliance certification
• Matching MSL rating and environmental operating range
• Enhanced ingress protection specification (IP67) in the substitute part, providing superior environmental sealing

For applications currently specified with 1605798, direct substitution with 1620663 is permissible without design modification. The IP67 rating of 1620663 represents an improvement in environmental protection and does not introduce incompatibility.

Frequently Asked Questions (FAQ)

Q: Can 1620663 directly replace 1605798 in existing designs?

A: Yes. Both parts are Phoenix Contact SM series receptacle housings with identical position counts (6), shell size (M40-6), contact configurations (2.0mm and 3.6mm), mounting type (panel mount, right angle), and operating temperature range (-40°C to 125°C). No design changes are required.

Q: What is the primary difference between these parts?

A: The main difference is product lifecycle status. 1605798 is Last Time Buy (discontinued production), while 1620663 is Active (current production). Additionally, 1620663 specifies IP67 ingress protection, whereas 1605798 does not specify an IP rating.

Q: Are the contact sizes identical?

A: Yes. Both parts use 2.0mm contacts for 2 positions and 3.6mm contacts for 4 power positions, maintaining the same pin configuration and mating compatibility.

Q: Does the IP67 rating of 1620663 affect compatibility?

A: No. The IP67 rating indicates enhanced environmental sealing in 1620663 and does not create incompatibility. This represents an improvement in environmental protection.

Q: Are both parts RoHS compliant?

A: Yes. Both 1605798 and 1620663 are RoHS compliant and carry MSL rating 1 (Unlimited).

Q: What is the packaging format?

A: Both parts are supplied in Bulk packaging. Contacts are not included with either housing.
