Weidmüller 995031 Terminal Block: Equivalent & Substitute Parts

Part Overview

The Weidmüller 995031 is a 12-position wire-to-board terminal block with 5mm pitch, designed for horizontal mounting through PCB holes. This component features side-entry interlocking capability and screw-clamping wire termination rated for 15A at 300V. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 995031 is determined by strict alignment of the following core parameters:

• Position count and pitch: Must be 12 positions at 0.197" (5.00mm) spacing
• Mounting configuration: Through-hole PCB mounting with horizontal board orientation
• Electrical ratings: Minimum 15A current and 300V voltage capability
• Wire gauge compatibility: Support for 12-26 AWG conductors
• Termination method: Screw-based wire clamping mechanism
• Interlocking feature: Side-entry interlocking capability

The two substitute parts listed below meet these core substitution criteria. Variations in current rating (18A and 16A respectively), screw thread size (M2.6 and M3), torque specifications, and operating temperature ranges represent acceptable engineering tolerances within the terminal block category and do not preclude functional equivalence for the specified application parameters.

Engineering Selection Recommendations

Phoenix Contact 1935268 is an active-status substitute with higher current capacity (18A) and ROHS3 compliance. This part is suitable for applications where regulatory compliance with current RoHS3 standards is required. The M2.6 screw thread differs from the original M3 specification; PCB hole sizing and assembly procedures must be verified for compatibility. Higher inventory availability (4720 units) supports supply chain continuity.

Eaton EM258512V is an active-status substitute with current rating (16A) closely aligned to the original specification and identical M3 screw thread. This part offers extended operating temperature range (-40°C to 105°C) and ROHS3 compliance. REACH Unaffected status matches the original part classification. This option minimizes mechanical redesign requirements due to matching screw thread specification.

Both substitutes maintain the core functional parameters: 12 positions, 5mm pitch, through-hole mounting, 300V rating, 12-26 AWG wire gauge support, and side-entry interlocking. Selection between these options depends on specific regulatory requirements, thermal operating conditions, and assembly tooling constraints.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1935268 be used as a direct replacement for Weidmüller 995031?

A: Functional substitution is possible. The M2.6 screw thread on the Phoenix Contact part differs from the M3 specification of the original. PCB hole diameter and assembly torque specifications must be verified. The higher current rating (18A vs 15A) does not prevent substitution for applications within the original 15A specification.

Q: What is the primary difference between the two substitute options?

A: The Eaton EM258512V maintains the M3 screw thread specification, minimizing mechanical redesign. The Phoenix Contact 1935268 uses M2.6 threads and requires PCB hole verification. Eaton offers extended temperature range (-40°C to 105°C) compared to the original (-20°C to 100°C).

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both Phoenix Contact 1935268 and Eaton EM258512V carry ROHS3 Compliant certification. The original Weidmüller 995031 is marked as "Not applicable" for RoHS status due to its obsolete classification.

Q: Does the difference in screw torque specification affect substitution?

A: Screw torque specifications reflect design differences in clamping mechanisms. Phoenix Contact specifies 0.35-0.4 Nm (M2.6 thread), while Eaton specifies 0.79 Nm (M3 thread). Assembly procedures must follow the substitute part manufacturer's torque recommendations to ensure proper wire termination.

Q: What is the impact of the different wire termination designs?

A: Weidmüller uses clamping yoke with tension sleeve; Phoenix Contact uses standard screw termination; Eaton uses rising cage clamp. All three methods are screw-based and support the specified 12-26 AWG wire gauge range. Termination method does not prevent functional substitution but may affect assembly procedure details.

Q: Can I use these substitutes interchangeably in existing designs?

A: Mechanical compatibility requires verification of PCB hole sizing (particularly for the M2.6 vs M3 difference) and assembly tooling. Electrical performance is equivalent within the specified parameters. Regulatory compliance status should be confirmed for your application's requirements.
