Phoenix Contact 1677636 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1677636 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG21 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1677636 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Type: Base - Box Mount (required match)
• Style: Side Entry (required match)
• Size: B10 (required match)
• Operating Temperature Range: -40°C to 125°C (required match)
• Housing Material: Aluminum, Die Cast (required match)

Secondary Compatibility Criteria:

• Ingress Protection Rating: IP65 minimum (equal or higher rating acceptable)
• Thread Size: PG21 or equivalent metric thread (M32 is mechanically compatible alternative)
• RoHS Compliance: Required for regulatory alignment

The substitute part 1082579 meets all primary criteria and exceeds secondary criteria through enhanced IP66/IP67 ingress protection rating and ROHS3 compliance. The transition from PG21 to dual M32 threading represents a design evolution within the same connector family, maintaining mechanical and electrical compatibility while providing improved sealing characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications: Phoenix Contact 1082579 is the designated substitute for 1677636. Both components share identical connector type, style, size classification, and operating temperature specifications. The substitute maintains full mechanical and electrical compatibility while providing enhanced ingress protection (IP66/IP67 versus IP65) and current product status (Active versus Obsolete).

Regulatory Compliance: Both parts meet RoHS requirements. The substitute carries ROHS3 compliance and REACH Unaffected status, providing superior regulatory alignment for new designs and long-term supply chain stability.

Thread Configuration Consideration: The transition from single PG21 to dual M32 threading in the substitute represents a design enhancement. M32 metric threading is mechanically equivalent to PG21 in industrial connector applications. The dual configuration provides redundant entry points, improving system flexibility without compromising sealing integrity.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1082579 directly replace 1677636 in existing installations? A: Yes. Both components are Base - Box Mount, Side Entry, B10 size connectors with identical operating temperature ranges and aluminum die-cast housing. Dimensional variance is minimal (less than 1mm across all axes). The substitute provides equal or superior performance across all specified parameters.

Q: What is the difference between PG21 and M32 threading? A: PG21 is a metric tapered thread; M32 is a metric parallel thread. Both are standard industrial connector threads. The substitute's dual M32 configuration provides two independent entry points versus the single PG21 entry on the original part. This represents a design evolution, not a limitation.

Q: Is the IP66/IP67 rating of the substitute compatible with IP65 system requirements? A: Yes. IP66/IP67 exceeds IP65 specifications. Higher ingress protection ratings are fully backward compatible with systems designed for lower ratings. The substitute provides enhanced environmental sealing without compromising existing system performance.

Q: What is the inventory status for these parts? A: 1677636 (obsolete): 1156 pcs available. 1082579 (active): 829 pcs available. The active status of 1082579 ensures long-term supply chain availability.

Q: Are there any compliance differences between the two parts? A: 1082579 carries ROHS3 Compliant and REACH Unaffected certifications, providing enhanced regulatory coverage compared to the RoHS Compliant status of 1677636. Both meet ECCN EAR99 and HTSUS 8538.90.8180 classifications.
