ELM103200 Equivalent & Substitute Parts Reference

Part Overview

The ELM103200 is a 10-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 product status and is RoHS Compliant. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and functional specifications align with the original component's design parameters, enabling direct replacement in applications where the primary part is unavailable or when inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the ELM103200 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Criteria:

10 positions per level (maintains connector density)
0.200" (5.08mm) pitch spacing (ensures PCB footprint compatibility)
Through-hole mounting type (preserves assembly method)
Screw-based wire termination with rising cage clamp (maintains connection reliability)
300 V voltage rating minimum (meets electrical requirements)
Interlocking side features (ensures mechanical stability)

The identified substitutes (1-1546074-0 and 1-282847-0) meet these core criteria. Both are manufactured by TE Connectivity AMP Connectors and feature identical pitch, position count, mounting method, and termination style. Differences in mating orientation angle (35° versus angled), current rating (17.5 A versus 10 A), and housing material (Polyamide PA66 versus PBT) do not preclude substitution when the application permits these variations.

Engineering Selection Recommendations

Both substitute parts (1-1546074-0 and 1-282847-0) maintain Active product status and exceed RoHS compliance requirements with ROHS3 certification. The TE Connectivity alternatives provide higher current capacity (17.5 A versus 10 A) and extended temperature range (-40°C to 105°C versus 0°C to 105°C), representing functional improvements over the original ELM103200 specification.

Selection between the two TE Connectivity options depends on color requirement: 1-1546074-0 is available in black (matching the original), while 1-282847-0 is supplied in green. Both parts carry REACH Affected status, indicating compliance with European chemical regulations.

The primary design difference—mating orientation angle (35° versus unspecified angled configuration)—requires verification that the PCB layout accommodates the TE Connectivity 35° angle specification. Wire gauge compatibility extends to 30 AWG on substitute parts, providing broader wire size accommodation than the original 28 AWG maximum.

Frequently Asked Questions (FAQ)

Q: Can 1-1546074-0 or 1-282847-0 be used as direct replacements for ELM103200?

A: Yes, both parts are functionally compatible substitutes. They maintain identical pitch (5.08mm), position count (10), mounting method (through-hole), and termination style (screw rising cage clamp). Verify that your PCB layout accommodates the 35° mating angle specification of the TE Connectivity parts.

Q: What is the difference between 1-1546074-0 and 1-282847-0?

A: Both parts are electrically and mechanically identical. The only difference is housing color: 1-1546074-0 is black, matching the original ELM103200, while 1-282847-0 is green. Select based on your assembly color-coding or visual identification requirements.

Q: Do the substitute parts support the same wire gauges as the ELM103200?

A: The ELM103200 supports 12-28 AWG wire. The TE Connectivity substitutes support 12-30 AWG, providing compatibility with smaller gauge wires. All three parts are compatible with the 12-28 AWG range.

Q: Are there temperature rating differences I should consider?

A: The ELM103200 operates to 105°C maximum. The TE Connectivity substitutes operate from -40°C to 105°C, providing extended low-temperature capability. Both meet the original specification's upper temperature limit.

Q: What is the current capacity difference?

A: The ELM103200 is rated for 10 A per position. The TE Connectivity substitutes are rated for 17.5 A per position. This higher rating on substitute parts does not affect compatibility and provides additional current capacity margin for your application.

Q: Do all three parts meet RoHS requirements?

A: Yes. The ELM103200 is RoHS Compliant. Both TE Connectivity substitutes are ROHS3 Compliant, representing a higher compliance standard. All three parts are suitable for RoHS-regulated applications.

Q: What is the screw torque specification for these terminal blocks?

A: All three parts—ELM103200, 1-1546074-0, and 1-282847-0—specify identical screw torque of 0.79 Nm (7.0 Lb-In). Use this torque value for wire termination on any of these parts.
