Weidmüller 912636 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 912636 is a 3-position end terminal block with direct mount configuration, rated for 70A at 600V UL, designed for screw termination of 6-22 AWG wire. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The beige polyamide housing with UL94 V-2 flammability rating provides standard industrial terminal block performance across the -50°C to 100°C operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 912636 is determined by alignment of the following critical parameters:

• Electrical Performance: Current rating (minimum 65A acceptable for 70A rated component), voltage rating (600V), and wire gauge compatibility (6-24 AWG encompasses 6-22 AWG)
• Mechanical Configuration: 3-position circuit capacity, screw termination method, and polyamide housing material
• Environmental Compliance: UL94 V-2 flammability rating and operating temperature range
• Termination Interface: Screw-based wire connection method

The Phoenix Contact 2716716 qualifies as a functional substitute based on these parameters. While classified as a barrier block connector rather than an end terminal, it maintains electrical equivalence through matching voltage/current ratings, wire gauge acceptance, and material specifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2716716 provides electrical and material equivalence to the obsolete Weidmüller 912636 across all specified parameters. The 65A current rating of the substitute remains within acceptable limits for applications originally designed for the 70A rated component, provided system load analysis confirms margin adequacy.

The transition from end terminal to barrier block configuration represents a mechanical form factor change. Physical mounting and panel integration requirements must be evaluated independently, as the substitute employs chassis/panel mounting versus the direct mount approach of the original component.

Both components maintain UL94 V-2 compliance and polyamide construction, ensuring equivalent environmental performance within specified operating ranges. The Phoenix Contact part carries active product status with ROHS3 compliance, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2716716 directly replace the Weidmüller 912636 in existing assemblies?

A: Electrical substitution is valid based on matching voltage, current, wire gauge, and termination specifications. Mechanical compatibility requires verification of mounting configuration, as the substitute uses chassis/panel mounting rather than direct mount. Physical dimensions and panel cutout requirements must be confirmed before installation.

Q: What is the significance of the current rating difference (70A vs. 65A)?

A: The 5A difference represents a 7% reduction in rated capacity. Substitution is acceptable when system load analysis confirms the application operates below 65A. For applications requiring the full 70A capacity, alternative substitutes should be evaluated.

Q: Are there compatibility concerns with wire gauge ranges?

A: The Phoenix Contact part accepts 6-24 AWG wire, which encompasses the original 6-22 AWG specification. All wire sizes compatible with the Weidmüller 912636 are accommodated by the substitute.

Q: What packaging considerations apply to the substitute part?

A: The Phoenix Contact 2716716 is supplied in bulk packaging, whereas the original part packaging is unspecified. Procurement quantities and handling procedures may differ accordingly.

Q: Does the barrier block configuration affect electrical performance?

A: No. The barrier block design maintains equivalent electrical isolation, current capacity, and voltage rating. The configuration difference is mechanical rather than electrical.

Q: What compliance certifications should be verified for the substitute?

A: Both components carry UL94 V-2 flammability certification. The Phoenix Contact part is ROHS3 compliant and REACH affected, whereas the original is REACH unaffected. Regulatory requirements for the target application must be confirmed.
