Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1751460000 is determined by the following critical parameters:

• Pitch (4.60mm): All substitute parts must maintain identical 0.138" (4.60mm) pitch for mechanical compatibility with mating headers
• Number of Positions (3): Substitute parts must have exactly 3 positions to match connector density
• Type (Plug, Female Sockets): Substitute parts must be plugs with female sockets to maintain electrical and mechanical interface compatibility
• Mounting Type (Free Hanging In-Line): Substitute parts must support free-hanging in-line mounting orientation
• Series (Omnimate BL): All substitute parts belong to the same Omnimate BL series, ensuring design compatibility
• Electrical Ratings: Substitute parts must meet or exceed the minimum IEC and UL voltage and current specifications
• Compliance: All substitute parts must maintain RoHS compliance and UL94 V-0 flammability rating

The two substitute parts (1597370000 and 2459060000) meet these criteria while offering enhanced electrical ratings and different termination technologies suited to various application requirements.

Parameter Comparison

Engineering Selection Recommendations

1597370000 (Screw-Clamping Termination)

This substitute is recommended for applications requiring screw-based wire termination with enhanced electrical capacity. It provides 17A IEC current rating (versus 6A for the main part) and extended operating temperature range to 100°C. The screw-clamping yoke termination offers secure mechanical connection with defined torque specification (0.2-0.25 Nm). This part is active in production and maintains full RoHS compliance. Wire gauge compatibility extends to 14-28 AWG, accommodating broader conductor sizes than the original IDC design.

2459060000 (Screwless Push-In Termination)

This substitute is recommended for applications prioritizing tool-free installation and highest thermal performance. It delivers 17.5A IEC current rating with the widest operating temperature range (-50°C ~ 120°C) and supports wire gauges from 16-26 AWG. The screwless leg spring push-in termination eliminates screw assembly steps while maintaining secure connections. This part is active in production with ROHS3 compliance. The glass-filled nylon housing provides enhanced mechanical durability compared to standard PBT.

Both substitutes are active products within the Omnimate BL series, ensuring long-term availability and supply chain stability compared to the obsolete 1751460000.

Frequently Asked Questions (FAQ)

Q: Can 1597370000 or 2459060000 directly replace 1751460000 in existing applications?

A: Mechanical compatibility is confirmed through identical 4.60mm pitch, 3-position configuration, and free-hanging in-line mounting. However, wire entry orientation differs: the original supports 90° and 270° entry, while substitutes support 180° entry. Verify physical space constraints and wire routing in your application before substitution.

Q: What are the key differences in termination technology?

A: The original 1751460000 uses IDC (Insulation Displacement Contact) termination. Substitute 1597370000 uses screw-clamping yoke termination requiring a screwdriver and torque specification of 0.2-0.25 Nm. Substitute 2459060000 uses screwless push-in spring termination requiring no tools. Select based on your assembly process and maintenance requirements.

Q: Are the electrical ratings compatible with my existing system?

A: Both substitutes exceed the original electrical specifications. The 1751460000 is rated 6A IEC / 7A UL. Substitutes provide 17A IEC / 10A UL (1597370000) and 17.5A IEC (2459060000). If your system operates at or below the original ratings, both substitutes are electrically compatible. Verify your actual current draw does not exceed the original 6A IEC specification to ensure proper component selection.

Q: What wire gauges are supported by each part?

A: Original 1751460000 supports 20-22 AWG (0.35-0.5mm²). Substitute 1597370000 supports 14-28 AWG (0.2-1.5mm²). Substitute 2459060000 supports 16-26 AWG (0.14-1.5mm²). Ensure your wire gauge falls within the supported range of your selected substitute.

Q: Are both substitutes RoHS compliant?

A: Yes. The 1597370000 is RoHS Compliant. The 2459060000 is ROHS3 Compliant, representing the current RoHS directive standard. Both meet environmental compliance requirements for new designs and replacements.

Q: What is the operating temperature range for each part?

A: Original 1751460000 operates -50°C ~ 80°C. Substitute 1597370000 operates -50°C ~ 100°C. Substitute 2459060000 operates -50°C ~ 120°C. Select based on your application's thermal environment.

Q: Which substitute should I choose for new designs?

A: For new designs, either active substitute is appropriate. Choose 1597370000 if your assembly process includes screw termination tools and torque control. Choose 2459060000 if your process prioritizes tool-free assembly and requires maximum thermal performance. Both ensure long-term supply availability as active products.
