Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Weidmüller 1503960000 are grouped based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• 23-position configuration (mandatory)
• Female socket type (mandatory)
• Pitch tolerance: 0.200" (5.08mm) or 0.197" (5.00mm) (acceptable within mechanical tolerance)
• Free-hanging (in-line) mounting type (mandatory)
• Screw termination with clamp mechanism (mandatory)
• Wire gauge support: 14-26 AWG minimum (mandatory)
• UL94 V-0 flammability rating (mandatory)
• Tin contact mating finish (mandatory)

Secondary Variation Parameters:

• Plug wire entry angle (180°, 90°, or 270°)
• Termination clamp style (TOP clamp vs. rising cage clamp)
• Housing material composition
• Voltage and current ratings (IEC vs. UL standards)
• Operating temperature range
• RoHS compliance status

The substitute parts listed below maintain the primary compatibility criteria while offering variations in wire entry orientation and clamp mechanism design to accommodate different installation geometries and electrical performance requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (180° Wire Entry):

Phoenix Contact 1757226 provides the closest functional match to the Weidmüller 1503960000, maintaining the 180° wire entry orientation and 0.200" (5.08mm) pitch. This part is active in production with RoHS compliance and higher current rating (15A UL vs. 10A UL). The rising cage clamp termination mechanism differs from the TOP clamp design but maintains equivalent screw-based wire retention. This substitute is suitable for direct replacement in existing 180° wire entry installations.

Alternative Orientations (90° or 270° Wire Entry):

Amphenol ELFF23230 (90° wire entry, 5.08mm pitch) and Amphenol ELFF23240 (270° wire entry, 5.08mm pitch) maintain the exact 0.200" (5.08mm) pitch specification and are recommended when installation geometry requires angled wire entry. Both parts are active, RoHS compliant, and rated for 15A UL. These variants use rising cage clamp termination and polyphenylene oxide (PPO) housing material.

Amphenol ELFF23130 (90° wire entry, 5.00mm pitch) and Amphenol ELFF23140 (270° wire entry, 5.00mm pitch) offer alternative orientations with 0.197" (5.00mm) pitch. The 0.03mm pitch difference falls within standard mechanical tolerance for terminal block systems. These parts are active, RoHS compliant, and rated for 15A UL.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability rating and tin contact mating finish. Phoenix Contact 1757226 and all Amphenol ELFF variants are RoHS compliant, providing environmental compliance advantages over the obsolete Weidmüller part. Voltage ratings (300V UL) are consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1757226 be used as a direct replacement for Weidmüller 1503960000?

A: Yes. Both parts maintain 23 positions, 0.200" (5.08mm) pitch, 180° wire entry, female socket configuration, and free-hanging mounting. The primary difference is the termination clamp mechanism (rising cage vs. TOP clamp), which does not affect electrical or mechanical compatibility. Phoenix Contact 1757226 is active in production and RoHS compliant.

Q: What is the difference between TOP clamp and rising cage clamp termination?

A: Both mechanisms use screw-based wire retention. TOP clamp applies downward pressure from above the wire entry point. Rising cage clamp uses a cage mechanism that rises as the screw is tightened, securing the wire from the side. Both achieve equivalent wire retention and electrical contact. Selection depends on installation space and operator preference.

Q: Can I use Amphenol ELFF parts with 90° or 270° wire entry as substitutes?

A: Yes, if your installation geometry accommodates the different wire entry angle. ELFF23230 and ELFF23240 maintain the exact 0.200" (5.08mm) pitch. ELFF23130 and ELFF23140 use 0.197" (5.00mm) pitch, which is mechanically compatible within standard tolerance. All four parts are electrically and mechanically equivalent to the Weidmüller 1503960000 for 23-position female socket applications.

Q: What is the pitch difference between 5.08mm and 5.00mm, and does it matter?

A: The difference is 0.08mm (0.003"). This falls within standard mechanical tolerance for terminal block connector systems. Mating connectors designed for 5.08mm pitch will accommodate 5.00mm pitch parts without functional degradation. However, if your system uses precision-matched connector pairs, verify compatibility with the mating header specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. Phoenix Contact 1757226 and all Amphenol ELFF variants (ELFF23130, ELFF23140, ELFF23230, ELFF23240) are RoHS compliant. The original Weidmüller 1503960000 is listed as REACH Unaffected, indicating it predates RoHS requirements. Substitutes provide environmental compliance advantages for new designs and systems requiring RoHS certification.

Q: What wire gauge range do the substitute parts support?

A: Phoenix Contact 1757226 supports 12-30 AWG (0.2-2.5mm²), exceeding the original 14-26 AWG specification. Amphenol ELFF variants support 12-30 AWG, also exceeding the original range. All substitutes are compatible with the original 14-26 AWG wire gauge requirement and offer expanded capability for larger or smaller conductors.

Q: What is the current rating difference between the original and substitute parts?

A: The Weidmüller 1503960000 is rated for 10A (UL). Phoenix Contact 1757226 and all Amphenol ELFF variants are rated for 15A (UL). This represents a 50% increase in current capacity. If your application requires only 10A or less, all substitutes are suitable. If your application requires higher current, substitutes provide additional margin.

Q: Can I mix and match wire entry angles in a multi-connector installation?

A: Yes. The wire entry angle (180°, 90°, or 270°) is determined by installation geometry and does not affect electrical compatibility between connectors. You can use different wire entry angles in the same system if installation space requires it. All parts maintain the same 23-position, female socket, 5.08mm pitch (or 5.00mm for ELFF13x/14x variants) electrical interface.
