Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1607931 is determined by strict alignment of the following critical parameters:

• Connector Type & Series: Receptacle housing within the SM series
• Position Configuration: 8-position with identical pin arrangement (4 + 3 Power + PE)
• Shell Size: M40-8 insert specification
• Contact Specifications: Dual contact sizes (2.0mm and 3.6mm power)
• Mounting Configuration: Panel mount with right-angle orientation
• Environmental Rating: IP67 ingress protection
• Temperature Range: -40°C to 125°C operational limits
• Compliance: RoHS compliance requirement

The substitute part 1620664 maintains functional and dimensional equivalence across all critical parameters while differing in fastening mechanism (threaded versus push-twist) and shell material composition (metal versus gadolinium-zinc). These differences do not affect electrical or mechanical interchangeability within the connector interface.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1620664 serves as the active production equivalent for the 1607931. Both components maintain identical electrical and mechanical interface specifications within the SM series circular connector family. The 1620664 is currently in Active product status with higher inventory availability (1151 pcs versus 900 pcs), making it the preferred selection for new designs and ongoing procurement requirements.

The primary design consideration between these parts is the fastening mechanism: the 1607931 employs push-twist fastening while the 1620664 uses threaded fastening. This difference affects assembly procedure and backshell retention method but does not impact connector mating, contact integrity, or environmental sealing performance. Both parts maintain RoHS compliance and identical operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1620664 directly replace the 1607931 in existing assemblies?

A: Yes, the 1620664 is mechanically and electrically compatible. The connector interface, pin configuration, and environmental sealing are identical. The fastening mechanism difference (threaded versus push-twist) requires assembly procedure adjustment but does not affect functional performance.

Q: Are there differences in shell material between these parts?

A: The 1607931 uses gadolinium-zinc shell material while the 1620664 uses metal shell material. Both materials provide equivalent shielding and environmental protection at IP67 rating. Material selection does not affect electrical performance or interchangeability.

Q: What is the significance of the Last Time Buy status for the 1607931?

A: Last Time Buy status indicates Phoenix Contact has discontinued this part number. The 1620664 represents the active production alternative and should be specified for new designs and future procurement cycles.

Q: Do both parts support the same contact sizes and pin configurations?

A: Yes. Both the 1607931 and 1620664 accommodate 8 positions with identical contact sizing: four 2.0mm contacts and four 3.6mm power contacts, plus protective earth (PE) configuration.

Q: Are there inventory or lead time considerations between these parts?

A: The 1620664 maintains higher current inventory (1151 pcs) compared to the 1607931 (900 pcs). Given the Last Time Buy status of the 1607931, the 1620664 offers superior supply chain continuity for ongoing production requirements.
