Phoenix Contact 1677937 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1677937 is a heavy duty connector base designed for box mount applications with side entry configuration. This component features a B16 size connector with PG21 thread entry, IP65 ingress protection rating, and operates across an industrial temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1677937 is determined by the following critical parameters:

• Connector Type & Style: Must be Base - Box Mount with Side Entry configuration
• Size Classification: B16 size requirement for mechanical and electrical compatibility
• Housing Material & Construction: Aluminum die cast housing maintains thermal and mechanical properties
• Operating Temperature Range: -40°C to 125°C operational envelope
• RoHS & Environmental Compliance: ROHS3 compliance and REACH unaffected status

The substitute part 1082601 maintains these core parameters while introducing enhanced ingress protection (IP66/IP67 versus IP65) and dual M32 thread entry configuration. The dimensional envelope remains identical, and both parts share the same series designation within the HEAVYCON® product family.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1082601 serves as the active production equivalent for the obsolete 1677937. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial applications.

The primary distinction between these parts involves ingress protection rating and thread configuration. The 1082601 provides enhanced IP66/IP67 protection compared to the IP65 rating of the 1677937, with dual M32 thread entry replacing the single PG21 configuration. The identical dimensional footprint (117.00mm x 57.00mm x 84.00mm) and shared B16 size classification support direct mechanical integration in existing mounting structures.

For applications where the original PG21 thread specification is mandatory, mechanical adaptation may be required. For applications where enhanced water resistance and dust protection are beneficial, the 1082601 upgrade path is directly applicable without modification to the connector base mounting interface.

Frequently Asked Questions (FAQ)

Q: Can the 1082601 directly replace the 1677937 in existing installations?

A: Mechanical mounting compatibility is confirmed through identical dimensions and B16 size classification. Thread entry configuration differs (M32 dual versus PG21 single), requiring verification that cable gland or entry hardware can accommodate the M32 specification. Electrical and thermal operating parameters are equivalent.

Q: What is the significance of the IP66/IP67 upgrade in the 1082601?

A: The 1082601 provides enhanced ingress protection against dust and water immersion compared to the IP65 rating of the 1677937. This upgrade does not compromise compatibility with existing B16 connector interfaces and may provide improved environmental sealing for applications exposed to moisture or particulate contamination.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 1677937 and 1082601 operate across -40°C to 125°C, maintaining identical thermal performance specifications.

Q: What is the product status significance?

A: The 1677937 is classified as obsolete, indicating discontinued production. The 1082601 maintains active production status, ensuring availability for new designs and ongoing system support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial connector applications.
