Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-1546216-1 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 11 positions per level
• Through-hole mounting configuration
• Screw-based wire termination with rising cage clamp mechanism
• M3 screw thread specification
• Voltage rating of 300 V or greater
• Operating temperature range encompassing -40°C to 105°C

Secondary Compatibility Criteria:

• Wire gauge acceptance range that includes 15-17 AWG
• Current rating of 13.5 A or greater
• Horizontal board mating orientation
• Polyamide housing material

Substitute parts are grouped based on pitch tolerance and wire gauge accommodation. Parts with identical 5.00mm pitch and broader wire gauge ranges provide direct functional equivalence. Parts with slightly different pitch specifications (5.08mm) require mechanical verification for PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-282836-1 (Preferred Primary Substitute)

The 1-282836-1 provides direct functional equivalence to the 1-1546216-1. Both components share identical pitch (5.00mm), current rating (13.5 A), voltage rating (300 V), screw thread specification (M3), and housing material (PA66 Nylon 6/6). The 1-282836-1 accepts a broader wire gauge range (16-30 AWG) that encompasses the original specification (15-17 AWG). This part is active in production status and RoHS Compliant, supporting modern regulatory requirements. The 1-282836-1 is available in bulk packaging with 1384 units in stock.

Amphenol PCD ESLM11100 (Secondary Substitute)

The ESLM11100 maintains compatibility across all critical parameters: 11 positions, 5.00mm pitch, 13.5 A current rating, 300 V voltage rating, M3 screw thread, and PA66 housing material. This part accommodates wire gauges from 14-30 AWG, exceeding the original specification range. The ESLM11100 offers an extended operating temperature range (-40°C to 110°C) compared to the original (-40°C to 105°C). This part is active in production and RoHS Compliant. The ESLM11100 is supplied in tray packaging with 650 units in stock.

Phoenix Contact 1729212 (Tertiary Substitute with Limitations)

The 1729212 provides functional compatibility with notable parameter differences. The pitch specification is 5.08mm, representing a 0.08mm deviation from the original 5.00mm specification. This pitch difference requires verification against PCB footprint tolerances before implementation. The current rating is 10 A, which is lower than the original 13.5 A specification and may limit application scope. The 1729212 accepts wire gauges from 14-30 AWG and maintains 300 V voltage rating and M3 screw thread specification. This part is active in production and ROHS3 Compliant. The 1729212 is available in bulk packaging with 849 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the 1-282836-1 be used as a direct replacement for the 1-1546216-1?

A: Yes. Both parts share identical pitch (5.00mm), current rating (13.5 A), voltage rating (300 V), screw thread (M3), and housing material (PA66 Nylon 6/6). The 1-282836-1 wire gauge range (16-30 AWG) encompasses the original specification (15-17 AWG). No design modifications are required.

Q: What is the significance of the pitch difference between the 1-1546216-1 (5.00mm) and the 1729212 (5.08mm)?

A: The 0.08mm pitch difference affects PCB footprint spacing. While this difference is small, it must be evaluated against PCB design tolerances and mounting hole specifications. The 1729212 is suitable only if PCB layout accommodates the 5.08mm pitch specification.

Q: Why does the 1729212 have a lower current rating (10 A) compared to the original (13.5 A)?

A: The 1729212 is manufactured by Phoenix Contact using different internal conductor and contact geometry specifications. Applications requiring the full 13.5 A current capacity must use either the 1-282836-1 or ESLM11100.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1-282836-1 is RoHS Compliant, the 1729212 is ROHS3 Compliant, and the ESLM11100 is RoHS Compliant. The original 1-1546216-1 has RoHS status listed as not applicable due to its obsolete classification.

Q: What packaging options are available for these substitute parts?

A: The 1-282836-1 is supplied in bulk packaging (1384 units in stock). The 1729212 is supplied in bulk packaging (849 units in stock). The ESLM11100 is supplied in tray packaging (650 units in stock). Packaging selection depends on production volume and inventory management requirements.

Q: Can the ESLM11100 be used in applications with operating temperatures above 105°C?

A: Yes. The ESLM11100 supports operating temperatures up to 110°C, exceeding the original specification of 105°C. This extended temperature range provides additional design margin for thermal applications.

Q: Are there any compliance differences between the substitute parts?

A: The 1-282836-1 and ESLM11100 are both RoHS Compliant. The 1729212 is ROHS3 Compliant, representing a more recent regulatory standard. All three parts carry ECCN EAR99 and HTSUS 8536.90.4000 classifications. The 1-282836-1 and 1729212 are REACH Affected; the ESLM11100 REACH status is not specified in available data.
