Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1605846 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle housing for male pins, 8-position, SM series
• Shell Size & Insert: M40-8 specification for mechanical and electrical compatibility
• Contact Architecture: Mixed contact sizes (2.0mm signal, 3.6mm power) maintaining pin assignment integrity
• Mounting Specification: Panel mount with right-angle orientation and threaded flange fastening
• Electrical & Environmental Compliance: RoHS compliance and MSL rating of 1
• Mechanical Features: Metal shielded construction with rotatable backshell

The substitute part 1620664 maintains identical specifications across all these parameters, ensuring direct functional and mechanical interchangeability within the same application context.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1620664 is the direct substitute for the 1605846 based on the following engineering criteria:

Product Status Alignment: The 1605846 is designated Last Time Buy, indicating end-of-life status. The 1620664 maintains Active product status, ensuring continued availability and supply chain stability for new designs and production continuity.

Functional Equivalence: Both parts are identical across all critical mechanical and electrical parameters: connector type, position count, shell size, contact configuration, mounting specification, and shielding characteristics. This ensures drop-in compatibility within existing applications.

Compliance & Certification: Both parts maintain RoHS compliance and MSL rating of 1, satisfying regulatory and environmental requirements without modification to existing designs.

Enhanced Specifications: The 1620664 provides additional documented specifications including IP67 ingress protection rating and operating temperature range (-40°C ~ 125°C), offering improved environmental performance documentation compared to the main part.

Inventory Availability: The 1620664 is available in higher quantity (1151 pcs) compared to the 1605846 (727 pcs), supporting both immediate requirements and long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can the 1620664 be used as a direct replacement for the 1605846 in existing applications?

A: Yes. The 1620664 is mechanically and electrically identical to the 1605846 across all specified parameters. Both parts share the same SM series designation, M40-8 shell size, 8-position configuration with mixed contact sizes (2.0mm and 3.6mm), panel mount right-angle mounting, and metal shielded construction. No design modifications are required.

Q: What is the significance of the 1605846 being Last Time Buy?

A: Last Time Buy status indicates that Phoenix Contact has discontinued production of the 1605846. This designation signals the final opportunity to purchase existing inventory before the part becomes unavailable. The 1620664, with Active status, represents the current production equivalent and should be specified for new designs and future production runs.

Q: Are there any differences in contact compatibility between these two parts?

A: No. Both parts utilize identical contact specifications: 2.0mm contacts for signal pins and 3.6mm contacts for power pins, maintaining the same 4 + 3 Power + PE position architecture. Existing contact sets and mating connectors are fully compatible with both housing variants.

Q: Does the 1620664 provide any additional environmental protection?

A: The 1620664 is documented with IP67 ingress protection rating (dust tight, waterproof), whereas the 1605846 does not specify an ingress protection rating. Both parts feature metal shielded construction. The documented IP67 rating on the 1620664 provides explicit environmental performance specification for applications requiring moisture and dust resistance.

Q: What is the operating temperature range for these connectors?

A: The 1620664 specifies an operating temperature range of -40°C to 125°C. The 1605846 does not provide an operating temperature specification in the available documentation. For applications requiring defined thermal performance, the 1620664 provides explicit temperature range documentation.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1605846 and 1620664 are RoHS compliant and carry MSL rating of 1 (unlimited moisture sensitivity level), meeting regulatory requirements for hazardous substance restrictions and moisture handling.

Q: What is the difference in packaging and inventory status?

A: Both parts are supplied in bulk packaging. The 1605846 has 727 pcs available as new original stock, while the 1620664 has 1151 pcs available. The higher inventory level of the 1620664, combined with its Active product status, provides greater supply assurance for ongoing production requirements.
