Weidmüller 1290100000 Equivalent & Substitute Parts

Part Overview

The Weidmüller 1290100000 is a female insert for heavy duty connectors, featuring 6 positions with terminal block straight screw termination. This component is part of the Rockstar® DSTVK series and is classified as obsolete. Due to its obsolete status, identifying functionally compatible substitute parts is essential for system maintenance, repair, and new design implementations where equivalent performance characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Weidmüller 1290100000 are identified based on the following critical parameters that determine functional compatibility:

• Connector Type & Gender: Female insert configuration
• Termination Style: Terminal block with straight screw termination
• Size Classification: Size 3 form factor
• Electrical Ratings: Voltage and current handling capacity
• Contact Material & Finish: Copper alloy with silver finish for consistent electrical performance
• Series Compatibility: Rockstar® family connectors

The Weidmüller 1848550000 qualifies as a substitute part. While it introduces a ground position (6+Ground configuration) and operates at a reduced voltage rating of 500V compared to the original 600V specification, it maintains the same current rating of 16A, identical termination style, matching size classification, and equivalent contact material specifications. The addition of a dedicated ground position and enhanced housing material (polycarbonate with glass fill) represents a design evolution within the Rockstar® connector family.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1848550000 is an active product within the Rockstar® connector family and serves as a functional substitute for the obsolete 1290100000. Selection of the 1848550000 is appropriate for applications where:

• The system operates at or below 500V (the substitute's voltage rating)
• Current requirements do not exceed 16A
• The addition of a dedicated ground position provides system design benefits
• Compliance with UL94 V-2 flammability rating is acceptable
• Operating temperature range of -40°C to 110°C meets application requirements

The substitute part maintains electrical continuity through equivalent contact material and finish specifications, ensuring consistent signal integrity and connection reliability. Both parts are classified as REACH Unaffected and carry EAR99 ECCN designation.

Frequently Asked Questions (FAQ)

Q: Can the 1848550000 directly replace the 1290100000 in existing assemblies?

A: Direct mechanical and electrical substitution is possible within the constraints of the reduced voltage rating (500V vs. 600V) and the addition of a ground position. Physical form factor compatibility is maintained through identical Size 3 classification and matching termination style.

Q: What is the significance of the 6+Ground position configuration in the 1848550000?

A: The additional ground position provides a dedicated return path for grounding circuits. This represents a design enhancement in the Rockstar® DSTV-HE series compared to the earlier DSTVK series. Applications requiring separate ground termination benefit from this configuration.

Q: Are there voltage derating considerations when substituting the 1848550000 for the 1290100000?

A: Yes. The 1290100000 is rated for 600V operation, while the 1848550000 is rated for 500V. Applications operating above 500V require the original part or alternative substitutes rated for higher voltages.

Q: What is the inventory status of these parts?

A: The 1290100000 (obsolete) has 874 pieces in stock. The 1848550000 (active) has 649 pieces in stock. Active product status indicates ongoing availability and manufacturer support for the 1848550000.

Q: Do both parts share the same contact material specifications?

A: Yes. Both parts use copper alloy contacts with silver finish, ensuring equivalent electrical performance and corrosion resistance characteristics.
