Phoenix Contact 1620456 Circular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1620456 is an 8-position circular connector receptacle housing designed for male pins with panel mount, right-angle configuration. This component features a rotatable backshell, shielded design, and IP67 ingress protection rating. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The substitute part maintains the core electrical and mechanical interface specifications while offering active product status and updated material specifications.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1628527 qualifies as a manufacturer-recommended substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle housing for male pins
• Number of positions: 8
• Shell size - insert: M17-8
• Mounting type: Panel mount, right angle
• Mounting feature: Flange
• Contact type: Crimp
• Orientation: N (Normal)
• Ingress protection: IP67/IP68 (exceeds original specification)
• RoHS compliance: Maintained
• ECCN classification: EAR99 (consistent regulatory status)

Substitution Logic: The 1628527 maintains electrical and mechanical interface compatibility through identical position count, shell size, mounting configuration, and crimp contact termination. Both parts accommodate the same mating connector and cable assembly specifications. The substitute part's enhanced IP68 rating and active product status provide improved availability and environmental protection compared to the obsolete original.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The Phoenix Contact 1628527 is the manufacturer-recommended substitute for the obsolete 1620456. Both parts maintain identical electrical interface specifications through matching position count, shell size, and crimp contact configuration. The substitute part's active product status ensures continued availability for procurement and supply chain planning.

Compliance Considerations: Both parts maintain RoHS compliance and EAR99 export classification. The substitute part's Gadolinium-Zinc shell material and enhanced IP68 ingress protection provide equivalent or improved environmental sealing performance compared to the original metal shell design.

Temperature Operating Range: The original part operates to 125°C maximum, while the substitute part operates to 105°C maximum. Applications requiring operation above 105°C require verification of thermal requirements against the substitute part's specification.

Fastening Mechanism Difference: The original part uses push-twist fastening, while the substitute part uses threaded fastening. This difference affects backshell engagement procedure but does not impact electrical or mechanical interface compatibility with mating connectors.

Frequently Asked Questions (FAQ)

Q: Can the 1628527 directly replace the 1620456 in existing assemblies? A: Yes. Both parts share identical shell size (M17-8), position count (8), mounting configuration (panel mount, right angle), and crimp contact termination. The mating connector and cable assemblies remain compatible.

Q: What is the significance of the shielding difference? A: The original 1620456 is shielded, while the substitute 1628527 is unshielded. Applications requiring electromagnetic shielding must evaluate whether the unshielded design meets system requirements. This represents a functional difference that may impact performance in noise-sensitive applications.

Q: Does the operating temperature difference affect substitution? A: The original part operates to 125°C; the substitute operates to 105°C. Applications operating above 105°C cannot use the substitute part. Applications operating within the 105°C limit are unaffected.

Q: What is the difference between push-twist and threaded fastening? A: Push-twist fastening (original) and threaded fastening (substitute) represent different backshell engagement mechanisms. Both provide secure connection but require different assembly procedures. Consult assembly documentation for the specific fastening method required.

Q: Are there inventory considerations for this substitution? A: The original 1620456 has 1062 pieces in stock with obsolete status. The substitute 1628527 has 993 pieces in stock with active product status. For new designs, the active substitute part is recommended to ensure long-term availability.

Q: What does the IP67/IP68 rating difference mean? A: The original part is rated IP67 (dust tight, waterproof to 1 meter for 30 minutes). The substitute part is rated IP67/IP68 (dust tight, waterproof to 3 meters for extended periods). The substitute provides enhanced environmental protection.
