Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1751430000 is based on the following critical parameters that must align for functional compatibility:

Core Compatibility Criteria:

• Series: Omnimate BL (same connector family)
• Number of Positions: 7 (identical pin count)
• Pitch: 0.138" (4.60mm) (identical spacing for mating)
• Type: Plug, Female Sockets (same gender and socket configuration)
• Mounting Type: Free Hanging (In-Line) (same installation method)
• Contact Material: Copper Alloy (same electrical properties)
• Housing Material: Polybutylene Terephthalate (PBT) or equivalent (same mechanical durability)
• Ingress Protection: IP20 (same environmental sealing)
• RoHS Compliance: Required (regulatory alignment)

Allowable Variations:

• Plug Wire Entry angle (90°/270° vs. 180°) - different mechanical orientation
• Termination Style (IDC vs. Screw-based vs. Screwless) - different wire attachment methods
• Current and Voltage ratings (within or exceeding original specifications)
• Wire Gauge range (broader ranges acceptable if minimum/maximum encompass original range)
• Operating Temperature range (extended ranges acceptable)
• Product Status (Active preferred over Obsolete)

The two substitute parts listed below maintain core compatibility while offering enhanced electrical performance and modern termination technologies.

Parameter Comparison

Engineering Selection Recommendations

1597410000 - Screw-Based Termination Variant

The 1597410000 maintains PBT housing material identical to the original 1751430000 and offers screw-clamping termination. This part is active in production and RoHS compliant. The wire entry angle differs (180° vs. 90°/270°), requiring mechanical layout adjustment. Current and voltage ratings exceed the original specification (17A IEC vs. 6A IEC; 320V IEC vs. 250V IEC). Wire gauge range is broader (14-28 AWG vs. 20-22 AWG), providing greater flexibility for wire selection. Operating temperature extends to 100°C compared to the original 80°C maximum.

2459100000 - Screwless Spring Cage Variant

The 2459100000 features push-button actuated screwless termination with spring cage technology, eliminating screw-based assembly. Housing material transitions to glass-filled polyamide, offering enhanced mechanical durability. This part is active in production and RoHS compliant. Current and voltage ratings exceed the original (17.5A IEC vs. 6A IEC; 320V IEC vs. 250V IEC). Wire gauge range spans 16-26 AWG, encompassing the original 20-22 AWG specification. Operating temperature extends to 120°C, providing the widest thermal operating window. Wire entry angle is 180°, requiring mechanical repositioning from the original 90°/270° configuration.

Selection Basis:

Both substitutes are active products from the same Omnimate BL series with identical 7-position, 4.6mm pitch configuration. Selection between them depends on termination method preference: screw-based (1597410000) for traditional assembly or screwless (2459100000) for faster installation and push-button convenience. Both exceed the electrical performance of the obsolete 1751430000 and maintain full RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can 1597410000 or 2459100000 directly replace 1751430000 without modification?

A: Both substitutes maintain the same 7-position, 4.6mm pitch configuration and free-hanging in-line mounting, ensuring mechanical compatibility with mating connectors. However, wire entry angle differs (180° vs. 90°/270°), requiring adjustment of wire routing geometry in the application. Termination method also changes from IDC to either screw-clamping or screwless spring cage, necessitating assembly procedure updates.

Q: Are the electrical ratings of the substitutes compatible with circuits designed for 1751430000?

A: Yes. Both 1597410000 and 2459100000 exceed the original electrical specifications. The 1751430000 is rated 6A at 250V (IEC), while 1597410000 provides 17A at 320V and 2459100000 provides 17.5A at 320V. Higher-rated components are suitable for circuits designed for lower ratings. Wire gauge ranges of both substitutes encompass the original 20-22 AWG specification.

Q: What is the primary difference between 1597410000 and 2459100000?

A: The primary difference is termination technology. 1597410000 uses screw-clamping (Tension Sleeve) requiring M2 screws with 0.2-0.25 Nm torque. 2459100000 uses screwless spring cage (Tension Clamp) with push-button actuation, eliminating screw assembly. Housing material also differs: 1597410000 retains PBT while 2459100000 uses glass-filled polyamide. Operating temperature range extends to 120°C on 2459100000 versus 100°C on 1597410000.

Q: Are both substitutes RoHS compliant?

A: Yes. Both 1597410000 and 2459100000 are RoHS compliant, matching the compliance status of the original 1751430000. All three parts carry RoHS Compliant designation.

Q: What packaging is available for the substitute parts?

A: Both 1597410000 and 2459100000 are supplied in bulk packaging. Inventory availability is 897 pcs for 1597410000 and 681 pcs for 2459100000.

Q: Can wire gauge be mixed between the original and substitute parts in the same application?

A: Wire gauge selection must be based on circuit current requirements and application standards. The original 1751430000 accepts 20-22 AWG. Substitute 1597410000 accepts 14-28 AWG and 2459100000 accepts 16-26 AWG. Within a single connector, all positions should use wire gauges within the specified range for that part number to ensure consistent contact pressure and electrical performance.
