ELM073200 Equivalent & Substitute Parts Reference

Part Overview

The ELM073200 is a 7-position wire-to-board terminal block manufactured by Amphenol PCD, designed for through-hole PCB mounting with angled orientation. This component operates at 300 V with a 10 A current rating and accommodates wire gauges from 12-28 AWG using screw-based rising cage clamp termination. The part is RoHS compliant and currently in active production status with 832 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the critical parameters that define terminal block functionality: pitch, position count, voltage rating, current capacity, wire gauge range, mounting type, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM073200 is determined by strict equivalence in the following critical parameters:

• Position Count & Pitch: Both substitute parts maintain 7 positions at 0.200" (5.08mm) pitch, ensuring PCB footprint compatibility
• Voltage & Current Ratings: Substitute parts meet or exceed the 300 V voltage requirement; current ratings of 17.5 A exceed the 10 A requirement
• Wire Gauge Compatibility: Substitute parts accept 12-30 AWG, which encompasses the 12-28 AWG range of the main part
• Mounting & Termination: All parts use through-hole mounting with screw-based rising cage clamp termination
• Mating Orientation: Substitute parts feature 35° (145°) angle orientation, differing from the angled orientation of ELM073200
• Compliance: All parts maintain RoHS compliance and MSL Level 1 rating

The identified substitutes are TE Connectivity AMP Connectors parts 1546074-7 and 282847-7 from the Buchanan series.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity AMP Connectors substitutes (1546074-7 and 282847-7) meet the electrical and mechanical requirements for applications currently using the ELM073200. Selection between alternatives should be based on the following factors:

1546074-7 (Black Housing)

• Maintains black housing color matching the original ELM073200
• Provides extended operating temperature range (-40°C ~ 105°C) compared to the main part's single upper limit specification
• ROHS3 compliant, exceeding RoHS baseline compliance
• Higher current capacity (17.5 A) provides design margin above the 10 A requirement
• Expanded wire gauge acceptance (12-30 AWG) accommodates broader conductor sizes

282847-7 (Green Housing)

• Identical electrical specifications to 1546074-7
• Green housing color differs from the original black specification
• RoHS compliant status confirmed
• Highest inventory availability (1835 units) among all options
• Operating temperature range not specified in available data

Orientation Consideration Both substitutes feature 35° (145°) angle orientation, which differs from the angled orientation of ELM073200. PCB layout compatibility must be verified before selection.

Frequently Asked Questions (FAQ)

Q: Can 1546074-7 or 282847-7 be used as direct replacements for ELM073200?

A: Both parts maintain electrical equivalence (300 V, wire gauge compatibility, screw termination) and mechanical compatibility (7 positions, 5.08mm pitch, through-hole mounting). However, the 35° (145°) angle orientation differs from the ELM073200's angled orientation. PCB footprint and connector approach angle must be verified for your specific application before substitution.

Q: What is the difference between 1546074-7 and 282847-7?

A: Both parts are electrically and mechanically identical. The primary differences are housing color (black vs. green) and operating temperature specification (1546074-7 specifies -40°C ~ 105°C; 282847-7 does not specify a temperature range). Inventory levels differ, with 282847-7 having higher stock availability.

Q: Do the substitute parts support the same wire gauge range?

A: The substitute parts accept 12-30 AWG, which encompasses the ELM073200's 12-28 AWG range. The expanded range provides compatibility with larger conductor sizes if required by future design iterations.

Q: Are there compliance differences between the main part and substitutes?

A: All parts are RoHS compliant. The 1546074-7 carries ROHS3 certification, representing a higher compliance standard. All parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating. Both substitutes are REACH Affected, which should be verified against your supply chain requirements.

Q: What is the current rating difference, and does it matter?

A: The ELM073200 is rated for 10 A, while both substitutes are rated for 17.5 A. The higher rating in substitute parts provides additional design margin and does not create compatibility issues for applications operating within the 10 A specification.

Q: How do housing materials differ between the parts?

A: The ELM073200 uses Polybutylene Terephthalate (PBT), while both substitutes use Polyamide (PA66), Nylon 6/6. Both materials are suitable for terminal block applications and maintain the required electrical insulation properties at the specified voltage and temperature ratings.
