Weidmüller 1612250000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1612250000 is a 3-position terminal block plug with blade pins, 7.00mm pitch, designed for free-hanging in-line mounting applications. This component features screw-top clamp termination and operates across -50°C to 100°C with a maximum current rating of 24A (IEC) and 17A (UL) at 600V. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1612250000 is determined by the following critical parameters:

• Number of Positions: Must remain 3 positions to maintain circuit connectivity
• Mounting Type: Must be free-hanging in-line to fit existing mechanical installations
• Plug Configuration: Must use blade pins for compatibility with mating receptacles
• Pitch Tolerance: Pitch variation affects mechanical fit; the substitute pitch of 7.62mm represents a 0.62mm increase from the original 7.00mm specification
• Termination Compatibility: Original screw-top clamp termination differs from substitute push-in spring termination, requiring evaluation of installation procedures
• Electrical Ratings: Substitute provides higher current capacity (41A IEC, 35A UL) and voltage rating (1kV IEC), exceeding original specifications
• Wire Gauge Compatibility: Substitute accommodates 10-24 AWG (0.5-10mm²), expanding the wire range beyond the original 14-22 AWG specification
• Temperature Range: Substitute extends operating temperature to -50°C to 125°C, exceeding original -50°C to 100°C range
• Compliance: Both parts maintain RoHS compliance and UL94 V-0 flammability rating

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1060970000 serves as an active substitute for the obsolete 1612250000. Both components maintain identical compliance certifications (RoHS, UL94 V-0, IP20) and share the same fundamental architecture: 3-position blade pin plugs with 180° wire entry and free-hanging in-line mounting.

The substitute provides enhanced electrical performance with higher current capacity (41A IEC vs. 24A IEC) and extended temperature range (-50°C to 125°C vs. -50°C to 100°C). The pitch increase from 7.00mm to 7.62mm and termination method change from screw-top clamp to push-in spring require mechanical and installation procedure evaluation for specific applications.

The substitute's expanded wire gauge compatibility (10-24 AWG vs. 14-22 AWG) and higher voltage rating (1kV IEC) provide additional design flexibility. Selection should be based on mechanical fit constraints, installation methodology compatibility, and whether the enhanced electrical ratings align with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1060970000 directly replace the 1612250000 in existing installations?

A: Direct mechanical replacement requires verification of pitch compatibility. The 0.62mm pitch increase may affect fit with existing mating receptacles and mounting hardware. Installation methodology differs due to termination style change from screw-top clamp to push-in spring.

Q: What are the key differences in electrical performance?

A: The substitute provides higher current capacity (41A IEC vs. 24A IEC), extended voltage rating (1kV IEC vs. no IEC rating specified), and broader wire gauge acceptance (10-24 AWG vs. 14-22 AWG). Both maintain 600V UL rating.

Q: Are there compatibility concerns with wire gauge ranges?

A: The substitute accommodates a wider wire range (0.5-10mm² vs. 0.5-2.5mm²). Applications using the original 14-22 AWG specification fall within the substitute's compatible range.

Q: How does the termination style change affect installation?

A: The original uses screw-top clamp termination requiring torque application (0.5-0.6 Nm). The substitute uses screwless push-in spring termination, eliminating screw torque procedures but requiring different insertion techniques.

Q: Are both parts RoHS and UL compliant?

A: Yes. Both the 1612250000 and 1060970000 are RoHS compliant, maintain UL94 V-0 flammability rating, and carry IP20 ingress protection classification.

Q: What is the significance of the product status difference?

A: The 1612250000 is obsolete, making the active 1060970000 the recommended path for new designs and ongoing system support. Inventory availability favors the substitute for future procurement.
