Phoenix Contact 1774021 SZHV10/16 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1774021 is a panel mount base connector for the HEAVYCON® HV series, designed for bottom entry applications with IP65 ingress protection. This connector features a die-cast aluminum housing with powder coating, rated for operating temperatures from -40°C to 125°C, and is RoHS compliant.

The 1774021 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring bottom entry panel mount connectors with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1774021 is based on the following critical parameters that define functional equivalence:

• Connector Type & Style: Panel mount base with bottom entry configuration
• Housing Material & Construction: Die-cast aluminum for mechanical durability
• Ingress Protection: IP65 minimum rating for dust and water resistance
• Operating Temperature Range: -40°C to 125°C compatibility
• Regulatory Compliance: RoHS compliance status
• Lock Mechanism: Locking clip on base bottom

The substitute part 1411329 maintains these core functional parameters while representing an evolution within the Phoenix Contact heavy duty connector portfolio, transitioning from the HEAVYCON® HV series to the HEAVYCON® EVO series with enhanced ingress protection capabilities.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1411329 (SZHV24 from the HEAVYCON® EVO series) serves as the primary substitute for the obsolete 1774021. Both connectors maintain identical operating temperature ranges (-40°C to 125°C) and share the same fundamental panel mount, bottom entry architecture with die-cast aluminum construction.

The 1411329 provides enhanced ingress protection (IP66/IP67/IP69K versus IP65) and is classified as an active product with current manufacturing support. Both parts maintain RoHS compliance, with the substitute meeting the more recent ROHS3 standard. The 1411329 includes salt water resistance as an additional feature, extending environmental durability.

Dimensional differences exist between the two parts, with the 1411329 measuring slightly larger (140.50mm x 53.00mm x 30.50mm versus 140.00mm x 43.00mm x 27.00mm). Panel cutout and mounting hole spacing must be verified for mechanical compatibility in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the 1411329 directly replace the 1774021 in existing installations?

A: Both connectors share the same connector type (panel mount base), style (bottom entry), lock mechanism (locking clip on base bottom), and operating temperature range. However, dimensional differences require verification of panel cutout dimensions and mounting hole spacing before installation.

Q: What is the difference in ingress protection between these parts?

A: The 1774021 provides IP65 protection (dust tight, water resistant). The 1411329 provides IP66/IP67/IP69K protection (dust tight, water resistant, and waterproof). The enhanced rating of the substitute offers greater environmental protection in demanding applications.

Q: Are both parts RoHS compliant?

A: Yes. The 1774021 is RoHS compliant. The 1411329 meets the more recent ROHS3 standard, which supersedes the original RoHS directive with stricter requirements.

Q: Why is the 1774021 listed as obsolete?

A: The 1774021 belongs to the HEAVYCON® HV series, which has been superseded by the HEAVYCON® EVO series. Phoenix Contact has transitioned product lines to the newer EVO platform, which offers enhanced performance and environmental protection ratings.

Q: What is the significance of salt water resistance in the 1411329?

A: Salt water resistance indicates the connector housing can withstand corrosive marine and coastal environments. This feature extends the operational lifespan in applications exposed to salt spray or saline conditions.

Q: Are there packaging differences between these parts?

A: The 1774021 is supplied in standard packaging. The 1411329 is supplied in bulk packaging, which may affect procurement quantities and logistics considerations.
