Engineering Selection Recommendations

Phoenix Contact 1777736 (Direct Substitute): This part is the primary replacement for the obsolete 1975590. Both components are manufactured by Phoenix Contact within the COMBICON PC series and maintain identical electrical specifications (41A IEC/UL, 1kV IEC, 600V UL). The 1777736 is currently in active production status with higher inventory availability (809 pcs vs. 684 pcs). The minor reduction in insulation height (0.776" vs. 0.902") and torque specification range adjustment (0.5-0.8 Nm vs. 0.7-0.8 Nm) do not affect functional compatibility. ROHS3 compliance and UL94 V-0 flammability rating are maintained. This substitute is suitable for direct replacement in existing designs.

Amphenol Anytek ET0301500000G (Similar Substitute): This part provides mechanical compatibility but with reduced electrical ratings. The 32A UL current and 300V UL voltage specifications are lower than the original 1975590 (41A, 600V). The ET0301500000G is appropriate only for applications where the lower electrical ratings are acceptable. The M4.6 screw size differs from the M3 specification of the original part. The minimum wire gauge of 2.5mm² (vs. 0.2mm²) may restrict compatibility with smaller gauge applications. This substitute offers significantly higher inventory availability (6466 pcs) and active product status. ROHS3 compliance and UL94 V-0 flammability rating are maintained. Operating temperature range is specified (-40°C to 115°C), providing additional environmental documentation.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1777736 be used as a direct replacement for 1975590?

A: Yes. The 1777736 maintains identical electrical ratings (41A IEC/UL current, 1kV IEC/600V UL voltage), mechanical configuration (3-position, 7.62mm pitch, 180° entry, screw termination), and housing material specifications. The insulation height reduction and torque range adjustment do not affect functional compatibility. Both parts are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What are the limitations of the Amphenol Anytek ET0301500000G substitute?

A: The ET0301500000G has reduced electrical ratings: 32A UL current (vs. 41A) and 300V UL voltage (vs. 600V). The screw size is M4.6 instead of M3, requiring different tooling. The minimum wire gauge is 2.5mm² (vs. 0.2mm²), which may exclude applications using smaller gauge conductors. Use this substitute only when application requirements fall within these reduced specifications.

Q: Are all three parts mechanically interchangeable?

A: The Phoenix Contact 1975590 and 1777736 are fully mechanically interchangeable. The Amphenol Anytek ET0301500000G maintains the same pitch, position count, and wire entry orientation but differs in screw size (M4.6 vs. M3) and insulation height (0.902" vs. 0.902" for the original). Mechanical fit in existing connector housings should be verified for the Amphenol part due to the M4.6 screw specification.

Q: What compliance certifications apply to these substitutes?

A: All three parts are ROHS3 compliant, UL94 V-0 flammability rated, and REACH unaffected. The 1975590 and 1777736 carry identical compliance documentation. The ET0301500000G maintains the same certifications with the addition of specified operating temperature range (-40°C to 115°C).

Q: Which substitute should be selected for new designs?

A: Phoenix Contact 1777736 is the recommended choice for new designs requiring direct compatibility with the obsolete 1975590 specifications. It maintains all electrical and mechanical parameters while offering active product status and established supply chain availability. The Amphenol Anytek ET0301500000G is suitable only when application requirements align with its reduced electrical ratings and M4.6 screw specification.

Q: How do packaging differences affect part selection?

A: The 1975590 was supplied in standard packaging, while the 1777736 is available in bulk packaging. The ET0301500000G is also bulk packaged. Packaging differences do not affect electrical or mechanical performance. Bulk packaging may offer cost advantages for high-volume applications but requires appropriate handling and storage procedures.
