Phoenix Contact 1773938 CONN HOOD TOP SZHV10/16 PG21 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1773938 is a heavy duty connector hood designed for top entry applications with PG21 thread size, rated IP65 for dust tight and water resistant environments. This connector belongs to the HEAVYCON® HV series and is currently marked as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for system maintenance, repair, and new design implementations where similar electrical and mechanical specifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1773938 is determined by the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Connector Type: Hood
• Style: Top Entry
• Thread Size: PG21
• Housing Material: Aluminum, Die Cast
• Operating Temperature Range: -40°C to 125°C
• RoHS Compliance: Required

Allowable Variation Parameters:

• Ingress Protection Rating: May be equal or superior (IP65 or higher)
• Series: May differ (HV to B series transition acceptable)
• Size: May differ if mechanical envelope remains compatible (HV10/16 to B24)

The Phoenix Contact 1412755 qualifies as a substitute part because it maintains all mandatory parameters while offering enhanced ingress protection (IP66/IP67/IP69K versus IP65) and represents an active product from the current HEAVYCON® B series portfolio.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412755 is the qualified substitute for the obsolete 1773938 based on the following engineering criteria:

Product Status Alignment: The 1412755 is an active product with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete 1773938.

Compliance Certification: Both parts maintain RoHS compliance, satisfying regulatory requirements for electronic component procurement in regulated industries.

Environmental Protection Enhancement: The 1412755 provides superior ingress protection (IP66/IP67/IP69K) compared to the original IP65 rating, offering enhanced performance in harsh environmental conditions including high-pressure water jets and salt water exposure.

Mechanical Compatibility: Both connectors share identical thread size (PG21), housing material (aluminum die cast), and operating temperature range (-40°C to 125°C), ensuring direct mechanical and thermal compatibility in existing installations.

Series Transition: The transition from HEAVYCON® HV series to HEAVYCON® B series represents Phoenix Contact's product line evolution, with the B24 size offering equivalent functional performance to the HV10/16 size within the same connector family.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1412755 directly replace the 1773938 in existing installations?

A: Yes. Both connectors share the same thread size (PG21), housing material (aluminum die cast), and operating temperature range (-40°C to 125°C). The 1412755 provides equal or superior performance with enhanced ingress protection ratings.

Q: What is the primary difference between these two connector models?

A: The main differences are product status (1773938 is obsolete; 1412755 is active), series designation (HV versus B), size designation (HV10/16 versus B24), and ingress protection rating (IP65 versus IP66/IP67/IP69K). The 1412755 offers superior environmental sealing.

Q: Are there any compatibility concerns when substituting the 1412755 for the 1773938?

A: No compatibility concerns exist for the specified parameters. Both connectors are manufactured from aluminum die cast housing, operate across the same temperature range, and maintain RoHS compliance. The enhanced ingress protection of the 1412755 provides additional environmental protection.

Q: What does the enhanced IP66/IP67/IP69K rating on the 1412755 provide compared to the IP65 rating?

A: IP66/IP67/IP69K provides protection against high-pressure water jets and temporary submersion, whereas IP65 provides protection against water jets from any direction. The 1412755 includes salt water resistance, making it suitable for marine and coastal applications.

Q: Is the 1412755 available in the same packaging as the 1773938?

A: The 1412755 is supplied in bulk packaging. Packaging specifications should be confirmed with the supplier based on specific procurement requirements.

Q: What is the inventory status of the substitute part?

A: The Phoenix Contact 1412755 has 735 pieces of new original stock available, ensuring immediate availability for replacement and new installations.
