Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1000540000 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: 10-position plug with female sockets
• Pitch & Spacing: 0.138" (4.60mm) center-to-center spacing
• Wire Entry Orientation: 180° free-hanging in-line configuration
• Termination Method: Screwless push-in spring mechanism
• Electrical Ratings: Minimum 2.2A (IEC) / 5A (UL) current capacity; 200V (IEC) / 50V (UL) voltage rating
• Wire Gauge Compatibility: Support for 16-24 AWG (0.2-1mm²) conductors
• Environmental & Compliance: UL94 V-0 flammability rating, RoHS compliance, IP20 ingress protection
• Temperature Range: -50°C to 75°C operating specification

The Weidmüller 1531180000 meets all substitution criteria as an active product within the Omnimate BL series, maintaining full electrical and mechanical compatibility with the obsolete 1000540000.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1531180000 is the direct active equivalent for the obsolete 1000540000. Both components are certified to identical electrical and mechanical specifications within the Omnimate BL series. The 1531180000 maintains full compatibility across all critical parameters: 10-position configuration, 4.60mm pitch, 180° wire entry, push-in spring termination, and equivalent current/voltage ratings.

Key differentiators between the parts are non-critical to substitution:

• The 1531180000 supports an extended wire gauge range (0.2-1.5mm² versus 0.2-1mm²), providing additional flexibility for conductor selection.
• The 1531180000 includes retention latches on the non-wire side, enhancing mechanical stability in the connector interface.
• The 1531180000 specifies an 8mm wire strip length, whereas the 1000540000 does not provide this specification.
• The 1531180000 has a greater insulation height (0.569" / 14.45mm versus 0.406" / 10.31mm), which may require verification in space-constrained applications.

Both parts carry RoHS compliance, UL94 V-0 flammability certification, and REACH unaffected status, ensuring regulatory alignment for industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1531180000 directly replace the 1000540000 in existing designs?

A: Yes. The 1531180000 is electrically and mechanically equivalent across all critical parameters: 10 positions, 4.60mm pitch, 180° wire entry, identical current/voltage ratings, and push-in spring termination. Both are Omnimate BL series components with matching contact materials and flammability ratings.

Q: What is the significance of the extended wire gauge range in the 1531180000?

A: The 1531180000 accepts conductors up to 1.5mm² (versus 1mm² for the 1000540000). This provides additional flexibility for applications requiring larger gauge wires, though the original 1000540000 specification remains fully supported.

Q: Does the increased insulation height of the 1531180000 affect compatibility?

A: The 1531180000 has an insulation height of 0.569" (14.45mm) compared to 0.406" (10.31mm) for the 1000540000. In space-constrained mounting environments, this dimensional difference must be verified against available clearance in the connector cavity or housing.

Q: Are there packaging differences between these parts?

A: The 1000540000 does not specify packaging details, while the 1531180000 is supplied in bulk packaging. This affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: What is the operational difference provided by retention latches in the 1531180000?

A: The 1531180000 includes retention latches on the non-wire side, which enhance mechanical stability and reduce the risk of accidental disconnection during handling or vibration. The 1000540000 does not include this feature.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 1000540000 and 1531180000 are RoHS compliant, REACH unaffected, and carry UL94 V-0 flammability certification. The 1531180000, as an active product, continues to meet current regulatory requirements for industrial terminal block applications.
