Equivalent & Substitute Parts for ELM033200

Part Overview

The ELM033200 is a 3-position wire-to-board terminal block manufactured by Amphenol PCD, designed for angled PCB mounting with 0.200" (5.08mm) pitch spacing. This component is classified as Active and is RoHS Compliant. Terminal blocks of this specification are essential in applications requiring reliable wire-to-board connections with screw-based termination and side interlocking features. Substitute parts may be required due to inventory availability, packaging preferences, or specific application requirements such as operating temperature range or current capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM033200 is determined by the following critical parameters:

• Position Count: Must be 3 positions per level
• Pitch Spacing: Must be 0.200" (5.08mm)
• Mounting Configuration: Must be through-hole PCB mounting
• Wire Termination Method: Must use screw-based rising cage clamp termination
• Voltage Rating: Must support minimum 300 V
• Interlocking Feature: Must include side interlocking capability
• Screw Torque Specification: Must match 0.79 Nm (7.0 Lb-In)

The substitute parts 1546074-3 and 282847-3 meet these core electrical and mechanical requirements. Both are manufactured by TE Connectivity AMP Connectors and share identical pitch, position count, mounting type, termination method, voltage rating, and torque specifications. Differences exist in mating orientation angle, current capacity, wire gauge range, housing material, color, and operating temperature range, which are secondary parameters that do not prevent functional substitution in applications where the ELM033200 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 1546074-3 and 282847-3 are Active products with current compliance certifications. The ELM033200 is RoHS Compliant, while 1546074-3 is ROHS3 Compliant and 282847-3 is RoHS Compliant, indicating all three parts meet environmental regulatory requirements.

Selection between the ELM033200 and its substitutes should be based on:

• Inventory Availability: 1546074-3 has 2,635 units in stock; 282847-3 has 20,560 units in stock; ELM033200 has 920 units in stock
• Packaging Format: ELM033200 is supplied in Tray packaging; both substitutes are supplied in Bulk packaging
• Current Capacity Requirements: If the application requires current ratings above 10 A, both substitutes provide 17.5 A capacity
• Operating Temperature Range: If extended low-temperature operation is required, 1546074-3 supports -40°C to 105°C; ELM033200 supports only 105°C maximum
• Housing Material Compatibility: ELM033200 uses PBT; substitutes use PA66/Nylon 6/6, which may affect thermal or chemical resistance in specific environments
• Wire Gauge Accommodation: Substitutes accept 12-30 AWG versus ELM033200's 12-28 AWG range

Frequently Asked Questions (FAQ)

Q: Can 1546074-3 or 282847-3 be used as direct replacements for ELM033200 on existing PCBs?

A: Yes, both substitute parts share identical pitch spacing (0.200"/5.08mm), position count (3), through-hole mounting configuration, and screw termination specifications. PCB footprints are compatible. Mating orientation differs slightly (35° angle versus angled), which may require verification of connector alignment in the specific application.

Q: What is the difference between 1546074-3 and 282847-3?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary differences are color (1546074-3 is black; 282847-3 is green), operating temperature specification (1546074-3 specifies -40°C to 105°C; 282847-3 does not specify minimum temperature), and REACH compliance status (1546074-3 is vendor undefined; 282847-3 is REACH Affected).

Q: Does the higher current rating of the substitute parts affect compatibility?

A: No. The substitute parts' 17.5 A rating is a higher capability than the ELM033200's 10 A rating. Applications designed for 10 A operation will function correctly with substitutes rated for 17.5 A.

Q: Are there packaging considerations when substituting?

A: Yes. The ELM033200 is supplied in Tray packaging, while both substitutes are supplied in Bulk packaging. Bulk packaging may require different handling, storage, or reel management procedures in manufacturing environments accustomed to tray-packaged components.

Q: Which substitute should be selected for low-temperature applications?

A: Part 1546074-3 explicitly specifies an operating temperature range of -40°C to 105°C, making it suitable for low-temperature environments. The ELM033200 and 282847-3 do not specify minimum operating temperatures and should not be assumed suitable for temperatures below 0°C without additional verification.
