Substitute Part Grouping Explanation

The Phoenix Contact 1628506 qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

  • Connector type: Receptacle housing for female sockets
  • Number of positions: 8 (7 + PE)
  • Shell size: M17-8
  • Mounting configuration: Panel mount, right angle
  • Contact termination: Crimp
  • Ingress protection: IP67/IP68
  • Orientation: Normal (N)
  • Shell material: Metal
  • RoHS compliance: Compliant
  • Manufacturer: Phoenix Contact

Substitution Logic: The 1628506 maintains electrical and mechanical compatibility through identical position count, shell size, mounting geometry, and contact interface specifications. Both connectors support the same M17-8 circular connector standard and panel-mount right-angle configuration. The substitute part is classified as active product status, ensuring continued availability and supply chain support.

Engineering Selection Recommendations

The Phoenix Contact 1628506 is the designated manufacturer-recommended substitute for the obsolete 1620451. Both parts maintain RoHS compliance and support identical mechanical and electrical interfaces for M17-8 circular connector applications.

Key Considerations:

The substitute part operates within a reduced maximum temperature range (-40°C to 105°C versus -40°C to 125°C). Applications requiring operation above 105°C must retain the original 1620451 specification or identify alternative solutions.

The 1628506 features unshielded construction compared to the shielded design of the 1620451. EMI-sensitive applications must evaluate whether the removal of shielding affects system performance.

Fastening mechanism differs: the original uses push-twist fastening while the substitute employs threaded fastening. Panel mount geometry and flange configuration remain compatible.

The substitute provides enhanced ingress protection (IP67/IP68 versus IP67) and specified electrical ratings (14A at 630V), supporting broader application flexibility.

Frequently Asked Questions (FAQ)

Q: Can the 1628506 directly replace the 1620451 in existing designs?

A: Mechanical and electrical interfaces are compatible for M17-8 panel-mount right-angle applications. Verify operating temperature requirements do not exceed 105°C and confirm that unshielded construction is acceptable for your application.

Q: What is the impact of the fastening type change from push-twist to threaded?

A: Both fastening methods secure the connector to the panel through the flange-mounted configuration. The threaded mechanism provides alternative engagement, but panel cutout and mounting hole specifications remain compatible.

Q: Does the removal of shielding affect signal integrity?

A: The 1620451 includes shielding while the 1628506 is unshielded. Applications transmitting high-frequency or noise-sensitive signals must evaluate whether shielding removal introduces unacceptable EMI coupling.

Q: Are there inventory considerations for the substitute part?

A: The 1628506 is classified as active product status with 1101 pieces in stock, ensuring supply continuity. The original 1620451 is obsolete with limited remaining inventory (1115 pieces).

Q: What electrical specifications apply to the substitute part?

A: The 1628506 is rated for 14A continuous current and 630V maximum voltage. Verify these ratings meet or exceed your application requirements.

Q: How do the operating temperature ranges compare?

A: The original 1620451 operates from -40°C to 125°C. The substitute 1628506 operates from -40°C to 105°C. Applications requiring operation above 105°C must use the original part or identify alternative solutions.
