Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1750830000 is determined by the following critical parameters:

• 6-position configuration with 0.138" (4.60mm) pitch spacing
• Female socket connector type
• 180° free-hanging in-line mounting orientation
• Copper alloy contacts with tin mating finish
• PBT or equivalent housing material
• RoHS compliance status
• Compatibility with wire gauges 20-22 AWG (0.35-0.5mm²) minimum

The substitute parts 1597400000 and 2459090000 maintain the core mechanical and electrical interface requirements while offering enhanced electrical ratings, improved termination methods, and active product status. Both substitutes preserve the 6-position, 4.60mm pitch configuration and free-hanging mounting, ensuring direct mechanical compatibility in existing connector receptacles.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain mechanical and electrical interface compatibility with the 1750830000 while offering active product status and enhanced electrical performance.

1597400000 is recommended for applications requiring screw-based termination with defined torque specifications (0.2-0.25 Nm). This part supports expanded wire gauge compatibility (14-28 AWG, 0.2-1.5mm²) and provides higher current capacity (17A IEC, 10A UL) with operating temperature range of -50°C to 100°C. The screw-clamping termination method offers secure, field-serviceable connections suitable for industrial control and power distribution applications.

2459090000 is recommended for applications requiring tool-free, spring-cage termination with rapid assembly. This part accommodates wire gauges 16-26 AWG (0.14-1.5mm²) and delivers the highest current rating (17.5A IEC) with extended operating temperature range (-50°C to 120°C). The screwless termination design reduces assembly time and eliminates torque specification concerns. Housing material is glass-filled polyamide, providing enhanced mechanical durability compared to standard PBT.

Both substitutes are RoHS compliant, feature UL94 V-0 flammability ratings, and maintain tin contact mating finish. Selection between them depends on termination method preference and specific application temperature and wire gauge requirements.

Frequently Asked Questions (FAQ)

Q: Can 1597400000 or 2459090000 directly replace 1750830000 in existing connector receptacles?

A: Yes. Both substitutes maintain the 6-position, 0.138" (4.60mm) pitch configuration and 180° free-hanging mounting orientation, ensuring mechanical compatibility with receptacles designed for the 1750830000.

Q: What is the primary difference between the two substitute parts?

A: The primary difference is termination method. The 1597400000 uses screw-clamping termination with defined torque specifications, while the 2459090000 uses screwless spring-cage termination. The 2459090000 also offers higher current capacity (17.5A vs. 17A IEC) and extended operating temperature range (-50°C to 120°C vs. -50°C to 100°C).

Q: Are the substitute parts compatible with the wire gauge range of the original 1750830000?

A: Yes. The original part supports 20-22 AWG (0.35-0.5mm²). Both substitutes support this range and extend compatibility to broader wire gauge ranges: 1597400000 supports 14-28 AWG (0.2-1.5mm²), and 2459090000 supports 16-26 AWG (0.14-1.5mm²).

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status ensures ongoing availability, technical support, and supply chain continuity. Obsolete parts face potential discontinuation and supply constraints, making active substitutes preferable for new designs and long-term system maintenance.

Q: Do both substitutes meet the same compliance standards as the original part?

A: Yes. Both substitutes are RoHS compliant, feature UL94 V-0 flammability ratings, and maintain tin contact mating finish. The 2459090000 carries ROHS3 compliance, representing the current regulatory standard.

Q: Which substitute is better for high-temperature applications?

A: The 2459090000 is rated for -50°C to 120°C operating temperature, compared to 1597400000 at -50°C to 100°C. For applications requiring sustained operation above 100°C, the 2459090000 is the appropriate selection.

Q: What packaging options are available for the substitute parts?

A: Both substitutes are supplied in Bulk packaging, suitable for production assembly and system integration workflows.
