Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1771749 is determined by strict alignment with the following critical parameters:

• Series Compatibility: Both parts must belong to the HEAVYCON® B24 series
• Connector Type & Gender: Insert configuration with male gender
• Position Count & Size: 24 positions in B24 form factor
• Termination Method: Screw termination required
• Electrical Ratings: Voltage rating of 600V; current rating must meet or exceed 15A
• Environmental Specifications: Operating temperature range of -40°C to 125°C
• Material & Contact Specifications: Copper alloy contacts with silver finish; housing material must maintain UL94 V-0 flammability rating
• Regulatory Compliance: RoHS compliance required

The substitute part 1648296 satisfies all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1648296 is the qualified substitute for the obsolete 1771749 model. Both components maintain identical electrical specifications (600V, with the substitute rated at 16A versus the original 15A), identical mechanical form factor (24-position B24 insert with screw termination), and equivalent environmental operating parameters (-40°C to 125°C).

The substitute part offers enhanced compliance status: while the original part carries RoHS compliance, the 1648296 achieves ROHS3 compliance and is REACH affected, reflecting current regulatory standards. The housing material differs (polycarbonate glass-filled versus polyamide nylon), yet both maintain the required UL94 V-0 flammability rating.

The 1648296 is currently in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 1648296 directly replace the 1771749 in existing applications?

A: Yes. Both parts share identical series designation (HEAVYCON® B24), connector type (insert), gender (male), position count (24), size (B24), and termination method (screw). Electrical ratings are compatible: the substitute's 16A rating exceeds the original 15A requirement. Operating temperature ranges and flammability ratings are identical.

Q: What is the difference in housing material between these parts?

A: The 1771749 uses polyamide (PA) nylon housing, while the 1648296 uses polycarbonate (PC) glass-filled housing. Both materials achieve UL94 V-0 flammability certification. The polycarbonate variant in the substitute part may offer enhanced mechanical durability in certain environmental conditions.

Q: Are there compliance differences between these parts?

A: The original part is RoHS compliant. The substitute part achieves ROHS3 compliance and is REACH affected, representing alignment with current European regulatory requirements. Both parts maintain equivalent environmental and electrical safety certifications.

Q: Why is the original part listed as obsolete?

A: The 1771749 has been discontinued by Phoenix Contact. The 1648296 represents the current production equivalent within the HEAVYCON® B24 series and is the recommended solution for new designs and replacement applications.

Q: Are packaging differences significant for component selection?

A: The original part packaging is unspecified in available documentation. The substitute part is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection should be based on procurement quantity requirements.
