Weidmüller 1687990000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1687990000 is a 13-position terminal block plug with female sockets, 0.138" (4.60mm) pitch, designed for 180° free-hanging in-line applications. This component features screw-clamping termination, rated for 17A (IEC) / 10A (UL) operation, and is part of the Omnimate BL series. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new designs requiring compatible interconnection solutions.

Substitute Part Grouping Explanation

Substitution eligibility for the 1687990000 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Identical current (17A IEC / 10A UL) and voltage (320V IEC / 300V UL) ratings
Mechanical Compatibility: Matching 13-position count, 0.138" (4.60mm) pitch, 180° wire entry orientation, and free-hanging in-line mounting configuration
Termination Compatibility: Identical screw-clamping yoke (tension sleeve) termination method
Wire Gauge Compatibility: Identical 14-28 AWG (0.2-1.5mm²) wire gauge range
Environmental Ratings: Matching operating temperature range (-50°C to 100°C), UL94 V-0 flammability rating, and IP20 ingress protection
Series Compatibility: Both parts belong to the Weidmüller Omnimate BL series

The substitute part 1687760000 meets all these criteria and is therefore a direct functional equivalent.

Engineering Selection Recommendations

The Weidmüller 1687760000 is the direct functional equivalent for the obsolete 1687990000. Both components are RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements. The 1687760000 maintains active product status, ensuring ongoing availability and manufacturer support.

The only non-functional differences are housing color (black versus orange) and packaging format (unspecified versus bulk). These differences do not affect electrical performance, mechanical compatibility, or thermal characteristics. The substitute part is suitable for direct replacement in all applications where the 1687990000 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the 1687760000 be used as a direct replacement for the 1687990000?

A: Yes. Both parts are identical in all electrical, mechanical, and environmental parameters. The 1687760000 is the active equivalent of the obsolete 1687990000 and provides full functional compatibility.

Q: Does the color difference (black versus orange) affect compatibility?

A: No. Housing color is a cosmetic attribute and does not impact electrical performance, mechanical fit, or thermal operation. Color selection is typically driven by application-specific identification or organizational standards.

Q: Are the wire gauge and termination specifications identical?

A: Yes. Both parts accept 14-28 AWG (0.2-1.5mm²) wire and use identical screw-clamping yoke (tension sleeve) termination with M2 screws and 0.2-0.25 Nm torque specification.

Q: What is the difference in packaging between these parts?

A: The 1687990000 packaging format is unspecified, while the 1687760000 is supplied in bulk packaging. This affects order quantities and handling but does not influence component performance or compatibility.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 1687990000 and 1687760000 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the current availability status of each part?

A: The 1687990000 is obsolete with 1090 pieces in stock. The 1687760000 is active with 886 pieces in stock, making it the recommended choice for new designs and ongoing procurement.
