• Shell size - insert: M17-8
• Mounting configuration: Panel mount, right angle with flange
• Contact termination: Crimp
• Ingress protection: IP67 (1628507 also rated IP68)
• Orientation: Normal (N)
• RoHS compliance: Both parts compliant
• ECCN classification: EAR99

Series Transition: The 1628507 represents an active product from the PRO series, replacing the obsolete ST series 1620452. This transition maintains functional compatibility while providing enhanced specifications and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1628507 is the manufacturer-designated substitute for the obsolete 1620452. Both components maintain identical mechanical and electrical interface specifications for the M17-8 8-position circular connector receptacle housing configuration.

Selection Basis:

The 1628507 provides active product status with current manufacturing support, ensuring long-term availability and supply chain continuity. Both parts carry RoHS compliance certification and maintain equivalent ingress protection ratings suitable for IP67-rated applications.

The 1628507 offers enhanced specifications including IP68 capability and defined electrical ratings (14A at 630V), providing additional performance margin for applications requiring higher reliability assurance. The transition from push-twist to threaded fastening in the 1628507 represents a design improvement in the PRO series.

Temperature operating range differs between the parts: the 1620452 supports -40°C to 125°C while the 1628507 operates -40°C to 105°C. Applications requiring operation above 105°C must evaluate this specification difference against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1628507 directly replace the 1620452 in existing installations?

A: Yes. Both components share identical M17-8 shell size, 8-position configuration, panel mount right-angle mounting, and crimp contact termination. The mechanical and electrical interfaces are compatible for direct substitution in applications operating within the 1628507 temperature range (-40°C to 105°C).

Q: What is the primary difference between these two parts?

A: The 1620452 belongs to the obsolete ST series, while the 1628507 is an active PRO series component. The 1628507 features threaded fastening versus push-twist, unshielded design versus shielded, and defined electrical ratings (14A, 630V). The 1620452 supports higher maximum operating temperature (125°C vs. 105°C).

Q: Are there shielding considerations for substitution?

A: The 1620452 is shielded while the 1628507 is unshielded. Applications requiring electromagnetic shielding must evaluate whether the unshielded 1628507 meets EMC requirements. If shielding is mandatory, alternative solutions within the PRO series should be investigated.

Q: What does the fastening type change from push-twist to threaded mean?

A: The 1628507 uses threaded fastening for backshell connection, replacing the push-twist mechanism of the 1620452. This represents a design enhancement providing more secure mechanical retention. Installation procedures will differ accordingly.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1620452 and 1628507 carry RoHS compliance certification, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is the inventory status for these parts?

A: The 1620452 has 988 pieces in stock as new original inventory. The 1628507 has 1056 pieces in stock as new original inventory in bulk packaging. Availability may vary by distributor and region.
