Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1751380000 is determined by the following critical parameters:

Core Compatibility Requirements:

• Manufacturer: Weidmüller (same family)
• Series: Omnimate BL (same connector family)
• Type: Plug, Female Sockets (same connector gender and socket configuration)
• Number of Positions: 2 (same circuit count)
• Pitch: 0.138" (4.60mm) (same contact spacing)
• Mounting Type: Free Hanging (In-Line) (same installation method)
• Termination Interface: Compatible with IDC or equivalent wire attachment methods

Electrical Performance Criteria:

• Current Rating: Substitute must meet or exceed 6A IEC / 7A UL
• Voltage Rating: Substitute must meet or exceed 250V IEC / 300V UL
• Wire Gauge Compatibility: Substitute must accommodate 20-22 AWG (0.35-0.5mm²) wire range

Environmental & Compliance:

• Operating Temperature: Substitute must support -50°C to 80°C minimum
• Material Flammability: UL94 V-0 rating maintained
• RoHS Compliance: Required for new applications

The two identified substitutes (1597360000 and 2458950000) meet these core requirements while offering enhanced electrical ratings and alternative termination methods suitable for the same application space.

Parameter Comparison

Engineering Selection Recommendations

1597360000 Selection Criteria: This substitute is recommended for applications requiring screw-terminal clamping termination. It provides enhanced current capacity (17A IEC vs. 6A IEC) and voltage rating (320V IEC vs. 250V IEC), with extended operating temperature range to 100°C. The screw-clamping termination method offers mechanical reliability for permanent installations. Wire gauge compatibility extends from 14-28 AWG, accommodating a broader range of conductor sizes. Product status is active with full RoHS compliance, ensuring long-term availability and regulatory alignment.

2458950000 Selection Criteria: This substitute is recommended for applications requiring push-in spring termination without screw fastening. It delivers the highest current capacity (17.5A IEC) and widest operating temperature range (-50°C to 120°C). The screwless push-in spring termination eliminates torque specification requirements and reduces assembly complexity. Wire gauge compatibility spans 16-26 AWG with superior lower-gauge support (0.14mm² vs. 0.35mm² minimum). Housing material is polyamide with glass reinforcement, providing enhanced mechanical durability. Product status is active with ROHS3 compliance, meeting current regulatory requirements.

Substitution Feasibility: Both substitutes maintain electrical compatibility with the original 1751380000 specification while exceeding minimum performance thresholds. Selection between substitutes depends on termination method preference and environmental operating temperature requirements. The 90°/270° wire entry orientation of the original part differs from the 180° straight entry of both substitutes; physical installation geometry must be evaluated for mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can 1597360000 or 2458950000 directly replace 1751380000 in existing installations?

A: Both substitutes maintain the same 2-position, 4.6mm pitch connector interface and female socket configuration. However, the wire entry angle differs: the original 1751380000 features 90° and 270° entry, while both substitutes use 180° straight entry. Physical installation space and wire routing must be evaluated before substitution. Electrical compatibility is confirmed across all IEC and UL ratings.

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

A: The 1597360000 uses screw-clamping termination with M2 screw specification (0.2-0.25 Nm torque), while the 2458950000 uses screwless push-in spring termination. The 2458950000 offers higher current capacity (17.5A vs. 17A IEC) and extended operating temperature to 120°C. Termination method selection depends on assembly process requirements and environmental conditions.

Q: Are both substitutes RoHS compliant?

A: Yes. The 1597360000 is RoHS Compliant, and the 2458950000 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What wire gauges are compatible with each substitute?

A: The 1597360000 accommodates 14-28 AWG (0.2-1.5mm²), and the 2458950000 accommodates 16-26 AWG (0.14-1.5mm²). The original 1751380000 specification of 20-22 AWG (0.35-0.5mm²) falls within both substitute ranges, ensuring wire compatibility.

Q: Can the original IDC termination be maintained with these substitutes?

A: No. The 1597360000 requires screw-clamping termination, and the 2458950000 requires push-in spring termination. IDC termination is specific to the original 1751380000. Wire attachment methodology must be adapted to the selected substitute's termination style.

Q: What is the operating temperature advantage of 2458950000?

A: The 2458950000 operates from -50°C to 120°C, compared to the original -50°C to 80°C range. This 40°C upper temperature extension is suitable for applications in elevated thermal environments. The 1597360000 extends to 100°C, providing a 20°C improvement over the original.

Q: Are there packaging differences between the substitutes?

A: Yes. The 1597360000 is supplied in bulk packaging, while the 2458950000 is supplied in box packaging. Inventory levels differ: 1597360000 has 8208 units available, and 2458950000 has 1173 units available. Packaging format may influence procurement and handling procedures.
