EL1M032B00 Equivalent & Substitute Parts

Part Overview

The EL1M032B00 is a 3-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with 0.200" (5.08mm) pitch spacing. This component is classified as Active product status and is RoHS Compliant. Terminal blocks of this specification are essential in industrial control systems, power distribution modules, and signal conditioning applications where reliable wire-to-board connections are required. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EL1M032B00 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Positions Per Level: 3
• Mating Orientation: Horizontal with Board
• Mounting Type: Through Hole
• Wire Termination: Screw - Rising Cage Clamp
• Features: Interlocking (Side)
• Voltage Rating: 300 V

Allowable Variation Parameters:

• Pitch: 0.200" (5.08mm) preferred; 0.197" (5.00mm) acceptable with design verification
• Current Rating: Minimum 15 A (EL1M032B00 rated 20 A)
• Wire Gauge: 12-30 AWG range acceptable; 18 AWG minimum
• Housing Material: Polyamide (PA) or Polyamide (PA66) acceptable
• Torque Specification: 0.5-0.6 Nm or 0.79 Nm acceptable
• RoHS Status: RoHS Compliant or ROHS3 Compliant acceptable
• MSL Rating: 1 or 3 acceptable

The five substitute parts listed below meet these criteria across different manufacturers, enabling functional equivalence while accommodating supply chain flexibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Preferred):

1711738 (Phoenix Contact COMBICON MKDS) and 282857-3 (TE Connectivity Buchanan) are the preferred substitutes. Both maintain the 0.200" (5.08mm) pitch specification matching the EL1M032B00 footprint. Part 282857-3 offers superior current rating at 24 A and matching torque specification of 0.79 Nm, making it suitable for applications requiring higher current capacity. Part 1711738 provides equivalent pitch and wire gauge compatibility with ROHS3 Compliant status and unlimited MSL rating.

Secondary Substitutes (Pitch Variation):

1711039 (Phoenix Contact COMBICON MKDS) and 1985975 (Phoenix Contact COMBICON MKDS) feature 0.197" (5.00mm) pitch, representing a 0.08mm deviation from the EL1M032B00 specification. These parts are suitable only when PCB layout permits minor pitch tolerance adjustment. Part 1985975 carries MSL-3 rating (168 hours), requiring controlled storage conditions compared to the EL1M032B00 MSL-1 rating.

Limited Substitution:

1707917 (Phoenix Contact COMBICON MKDS) restricts wire gauge to 18 AWG, eliminating compatibility with the full 12-30 AWG range of the EL1M032B00. This part is suitable only for applications using 18 AWG wire exclusively.

All substitute parts maintain 300 V voltage rating, through-hole mounting, screw-based rising cage clamp termination, and side-entry interlocking features. All parts carry RoHS or ROHS3 compliance status. Selection should prioritize pitch matching and current rating requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can 1711039 or 1985975 be used as direct replacements despite the 0.197" (5.00mm) pitch difference?

A: These parts feature 0.08mm pitch deviation from the EL1M032B00. Direct PCB substitution is not recommended without design review. The pitch difference may cause alignment issues with existing through-hole patterns. Use only when PCB layout accommodates the tolerance or when new PCB fabrication is planned.

Q: What is the significance of the current rating difference between EL1M032B00 (20 A) and Phoenix Contact substitutes (15 A)?

A: The EL1M032B00 supports 20 A continuous current. Phoenix Contact COMBICON MKDS parts are rated 15 A. In applications requiring sustained current above 15 A, use 282857-3 (24 A rating) or retain the original EL1M032B00. For circuits operating below 15 A, Phoenix Contact parts are functionally equivalent.

Q: Why does 1707917 specify only 18 AWG wire gauge when others support 12-30 AWG?

A: Part 1707917 is mechanically and electrically designed for 18 AWG wire termination. Using wire gauges outside this specification may result in improper clamp engagement or insufficient contact pressure. Use 1707917 only in applications where all connected wires are 18 AWG.

Q: What is the impact of MSL-3 rating on part 1985975 compared to MSL-1 rated alternatives?

A: MSL-3 (168 hours) indicates moisture sensitivity requiring controlled storage at ≤30% relative humidity and temperature ≤25°C. MSL-1 (unlimited) parts like EL1M032B00 and 282857-3 have no moisture sensitivity restrictions. For applications with extended storage or humid environments, prefer MSL-1 rated parts.

Q: Are torque specification differences between 0.5-0.6 Nm and 0.79 Nm critical for substitution?

A: Torque specifications define screw tightening force for proper wire clamping. The 0.79 Nm specification (EL1M032B00 and 282857-3) provides higher clamping force. Phoenix Contact parts at 0.5-0.6 Nm are designed for their respective contact geometry and provide adequate clamping within their current rating. Follow manufacturer-specified torque values during assembly.

Q: Can all substitute parts be used interchangeably in existing assemblies?

A: Interchangeability depends on pitch tolerance and current requirements. Parts matching 0.200" (5.08mm) pitch (1707917, 1711738, 282857-3) are mechanically interchangeable on existing PCBs. Parts with 0.197" (5.00mm) pitch (1711039, 1985975) require PCB modification. Verify current requirements before substitution.
