Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1751510000 is determined by the following core parameters:

• 8-position configuration with 4.6mm pitch spacing
• Female socket connector type
• Free-hanging in-line mounting orientation
• Copper alloy contacts with tin mating finish
• UL94 V-0 flammability rating
• IP20 ingress protection
• RoHS compliance and REACH unaffected status

The substitute parts 1597420000 and 2459110000 maintain these critical parameters while introducing variations in termination methodology (screw-clamping versus screwless spring cage), wire entry angle (180° versus 90°/270°), and electrical performance ratings. Both substitutes are active products within the Omnimate BL series, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain compliance with RoHS and REACH regulations, ensuring regulatory continuity. The 1597420000 and 2459110000 are active products with established supply chains, addressing the obsolescence status of the 1751510000.

Selection between substitutes depends on application-specific requirements:

The 1597420000 employs screw-clamping termination with M2 screw specification and defined torque parameters (0.2-0.25 Nm). This termination method accommodates wire gauges from 14-28 AWG and supports higher current ratings (17A IEC, 10A UL) compared to the original part. Wire entry is fixed at 180°, requiring board layout adjustment from the original 90°/270° configuration.

The 2459110000 utilizes screwless spring cage termination with push-button actuation, eliminating screw-based assembly steps. This variant supports wire gauges from 16-26 AWG with equivalent current ratings (17.5A IEC, 10A UL) and extends operating temperature range to -50°C ~ 120°C. Housing material differs, utilizing glass-filled polyamide instead of PBT. Wire entry remains at 180°.

Both substitutes exceed the original part's electrical performance specifications while maintaining mechanical compatibility within the Omnimate BL series framework.

Frequently Asked Questions (FAQ)

Q: Can the 1597420000 or 2459110000 directly replace the 1751510000 without PCB modifications?

A: Wire entry angle differs between the original part (90° and 270°) and both substitutes (180°). PCB layout modifications are required to accommodate the fixed 180° wire entry orientation. Mechanical mounting remains compatible as all three parts are free-hanging in-line configurations.

Q: What are the termination differences between the two substitute parts?

A: The 1597420000 uses screw-clamping termination requiring M2 screws with 0.2-0.25 Nm torque specification. The 2459110000 employs screwless spring cage termination with push-button actuation, eliminating manual screw assembly. Both methods provide equivalent electrical performance.

Q: Are the substitute parts compatible with the original wire gauge specifications?

A: The original 1751510000 accepts 20-22 AWG (0.35-0.5mm²). The 1597420000 accepts 14-28 AWG (0.2-1.5mm²) and the 2459110000 accepts 16-26 AWG (0.14-1.5mm²). Both substitutes accommodate the original wire gauge range with expanded capability for larger and smaller conductors.

Q: What is the impact of housing material differences?

A: The original part and 1597420000 use PBT (Polybutylene Terephthalate). The 2459110000 uses glass-filled polyamide (PA). Both materials maintain UL94 V-0 flammability rating and IP20 ingress protection. Material selection may affect thermal performance and mechanical rigidity in specific environmental conditions.

Q: Do both substitutes maintain the same electrical performance as the original part?

A: Both substitutes exceed the original specifications. The 1751510000 provides 6A IEC / 7A UL. The 1597420000 provides 17A IEC / 10A UL. The 2459110000 provides 17.5A IEC / 10A UL. Applications operating within the original part's current and voltage limits are fully compatible with either substitute.

Q: What is the operating temperature range difference?

A: The original part operates -50°C ~ 80°C. The 1597420000 extends to -50°C ~ 100°C. The 2459110000 extends to -50°C ~ 120°C. Applications requiring operation above 80°C benefit from the extended temperature range of the substitutes.
