WAGO 235-403 Terminal Block Equivalent & Substitute Parts

Part Overview

The WAGO 235-403 is a 3-position wire-to-board terminal block with horizontal board mounting and 0.200" (5.08mm) pitch spacing. This component is designed for PCB integration with screwless push-in spring termination, supporting 10 A at 300 V across wire gauges 14-20 AWG. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when application requirements permit equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WAGO 235-403 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Positions Per Level: 3
• Current Rating: 10 A minimum
• Voltage Rating: 300 V minimum
• Wire Gauge Compatibility: 14-20 AWG
• Mounting Type: Through Hole
• Mating Orientation: Horizontal with Board
• RoHS3 Compliance: Required

Allowable Variations:

• Pitch tolerance: ±0.003" (0.076mm) from 0.200" (5.08mm) nominal
• Operating temperature range: May be narrower than -60°C ~ 105°C
• Wire termination method: Alternative screwless technologies acceptable
• Housing material: Polyamide variants acceptable
• Contact plating: Copper-based systems acceptable
• Packaging format: Box or Bulk acceptable

The substitute part ED4101/3-KD from On Shore Technology Inc. qualifies within these parameters with documented equivalence across all mandatory criteria.

Engineering Selection Recommendations

WAGO 235-403 Primary Selection: The WAGO 235-403 maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. This component is suitable for applications requiring the extended operating temperature range of -60°C ~ 105°C. The leg spring and push-in spring termination provides dual-mode wire connection capability. Current inventory of 813 pieces supports immediate deployment.

On Shore ED4101/3-KD Substitute Selection: The ED4101/3-KD qualifies as a direct substitute when WAGO 235-403 availability is constrained. This part meets all mandatory electrical specifications (10 A, 300 V, 14-20 AWG) and maintains equivalent mechanical compatibility through through-hole mounting with 3-position horizontal board orientation. The pitch variance of 0.003" (0.08mm) remains within acceptable PCB layout tolerance for standard terminal block applications. RoHS3 compliance and EAR99 export classification match the primary part. The operating temperature range of -30°C ~ 105°C is suitable for standard industrial applications where the lower temperature limit of -30°C is acceptable. The push button clamp termination method provides equivalent screwless connection without requiring spring-leg configuration. Current inventory of 960 pieces supports alternative sourcing.

Selection Criteria:

• Use WAGO 235-403 when extended low-temperature performance (-60°C) is required
• Use On Shore ED4101/3-KD when standard industrial temperature range (-30°C ~ 105°C) is acceptable and primary part availability is limited
• Both parts satisfy regulatory compliance and export requirements
• Pitch tolerance of 0.003" is acceptable for standard PCB design margins

Frequently Asked Questions (FAQ)

Q: Can the On Shore ED4101/3-KD be used as a direct replacement for WAGO 235-403 on existing PCBs?

A: The ED4101/3-KD is compatible with PCBs designed for the WAGO 235-403. The pitch difference of 0.003" (0.08mm) falls within standard PCB manufacturing tolerances for terminal block footprints. Both parts use identical 3-position through-hole mounting with horizontal board orientation. Physical substitution on the PCB is feasible without redesign.

Q: What is the difference in wire termination between these two parts?

A: The WAGO 235-403 uses leg spring and push-in spring termination, providing two connection modes. The On Shore ED4101/3-KD uses push button clamp termination. Both are screwless systems. The ED4101/3-KD termination method is functionally equivalent for wire retention and electrical contact, with the difference being the mechanical actuation method for wire insertion and removal.

Q: Are there temperature-related limitations when substituting the ED4101/3-KD?

A: The ED4101/3-KD operates from -30°C to 105°C, compared to the WAGO 235-403 range of -60°C to 105°C. Applications requiring operation below -30°C must use the WAGO 235-403. For standard industrial environments operating above -30°C, the ED4101/3-KD is fully suitable.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the WAGO 235-403 and On Shore ED4101/3-KD are RoHS3 compliant with EAR99 export classification and identical HTSUS codes (8536.90.4000). Both carry unlimited moisture sensitivity rating (MSL 1). Regulatory compliance is equivalent.

Q: What is the significance of the pitch tolerance difference?

A: The WAGO 235-403 has a 0.200" (5.08mm) pitch, while the ED4101/3-KD has a 0.197" (5.00mm) pitch. This 0.003" difference is within standard PCB manufacturing tolerances (typically ±0.005" for terminal block footprints). The parts are mechanically interchangeable on standard PCB designs without layout modification.

Q: Can these parts be mixed in the same circuit or application?

A: Yes. Both parts meet identical electrical specifications (10 A, 300 V, 14-20 AWG wire gauge). They can be used in parallel applications or mixed within a single system design. The primary consideration is temperature range suitability for the specific application environment.

Q: What packaging differences exist between these parts?

A: The WAGO 235-403 is supplied in Box packaging with 813 pieces in current inventory. The On Shore ED4101/3-KD is supplied in Bulk packaging with 960 pieces in current inventory. Packaging format does not affect electrical or mechanical performance; it reflects supplier logistics and handling preferences.
