Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block connectors is determined by electrical compatibility and mechanical fit. The primary substitution criteria for the 305170 are:

Electrical Parameters (Critical):

• Current rating: minimum 115 A (UL) / 125 A (IEC)
• Voltage rating: minimum 600 V (UL) / 750 V (IEC)
• Termination style: Screw termination required
• Number of positions: 2 positions
• Number of levels: 1 level

Mechanical Parameters (Critical):

• Terminal width: 16.0 mm
• Wire gauge compatibility: must accommodate 2-10 AWG (6-16 mm²) minimum
• Feed-through configuration

Compliance Parameters:

• RoHS3 compliance required
• REACH compliance status alignment

The substitute part 304259 meets all critical electrical and mechanical parameters while maintaining equivalent compliance certifications. The expanded wire gauge range (2-12 AWG) of the substitute provides backward compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The 304259 terminal block connector is a direct functional equivalent to the obsolete 305170. Both components share identical electrical ratings (125 A IEC / 115 A UL, 750 V IEC / 600 V UL), mechanical configuration (2-position, 1-level, 16.0 mm terminal width, screw termination), and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The 304259 is classified as an active product, ensuring ongoing availability and supply chain continuity. The expanded wire gauge acceptance range (2-12 AWG versus 2-10 AWG) provides enhanced flexibility for conductor sizing while maintaining full backward compatibility with the original 305170 specification.

Both components utilize compatible insulation materials and flammability ratings appropriate for their respective electrical classifications. The 304259 is suitable for direct replacement in applications currently using the 305170.

Frequently Asked Questions (FAQ)

Q: Can the 304259 directly replace the 305170 in existing installations?

A: Yes. The 304259 meets all critical electrical and mechanical parameters of the 305170. Both components have identical current ratings (125 A IEC / 115 A UL), voltage ratings (750 V IEC / 600 V UL), terminal width (16.0 mm), screw termination, and 2-position configuration. The 304259 is an active product, addressing the obsolescence of the 305170.

Q: What is the difference in wire gauge acceptance between these parts?

A: The 305170 accepts 2-10 AWG (6-16 mm²), while the 304259 accepts 2-12 AWG (1.5-50 mm²). The 304259 range encompasses the original specification, providing compatibility with a broader range of conductor sizes without compromising the original application requirements.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the 305170 and 304259 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the product status difference between these components?

A: The 305170 is classified as obsolete, while the 304259 is an active product. This distinction ensures that the 304259 maintains current manufacturing support, supply availability, and compliance with evolving standards.

Q: Are there packaging differences between the 305170 and 304259?

A: The 304259 is supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility for terminal block connector applications.
