Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-1546216-2 terminal block are qualified based on the following critical parameters that determine functional and electrical equivalence:

Core Compatibility Parameters:

• 12-position configuration with 0.197" (5.00mm) pitch spacing
• 13.5 A current rating and 300 V voltage rating
• Through-hole mounting with horizontal board orientation
• Screw-based wire termination with rising cage clamp mechanism
• Polyamide (PA66) housing material
• Interlocking side-entry feature

Acceptable Variation Parameters:

• Wire gauge range (original: 15-17 AWG; substitutes may support extended ranges)
• Housing color (functional equivalence independent of color)
• Contact and clamp material composition (copper alloy or brass with equivalent plating)
• Operating temperature range (substitutes with equal or extended range)
• Product status transition (obsolete to active)
• RoHS and compliance certifications

Engineering Selection Recommendations

TE Connectivity 1-282836-2 (Primary Substitute)

The 1-282836-2 is the direct equivalent from TE Connectivity AMP Connectors within the Buchanan series. This part maintains identical electrical specifications (13.5 A, 300 V), mechanical configuration (12 positions, 5.00mm pitch), and termination method. The part is currently active with ROHS3 compliance certification. Wire gauge acceptance extends to 16-30 AWG, encompassing the original 15-17 AWG specification. This substitute is suitable for direct replacement in applications where the original 1-1546216-2 is specified, with the advantage of current product availability and regulatory compliance.

Amphenol PCD ESLM12100 (Alternative Substitute)

The ESLM12100 provides cross-manufacturer equivalence with identical electrical and mechanical parameters. This part supports an extended wire gauge range (14-30 AWG) and an elevated operating temperature ceiling (-40°C ~ 110°C versus -40°C ~ 105°C). The ESLM12100 is RoHS compliant and currently active. Selection of this alternative is appropriate when cross-manufacturer sourcing is required or when the extended temperature range provides operational advantage. Torque specification differs (0.5 Nm versus 0.68 Nm), requiring verification against application assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can the 1-282836-2 be used as a direct replacement for the 1-1546216-2?

A: Yes. Both parts share identical electrical ratings (13.5 A, 300 V), mechanical configuration (12 positions, 5.00mm pitch), mounting type (through-hole), and wire termination method (screw rising cage clamp). The 1-282836-2 is the active equivalent within the TE Connectivity product line.

Q: What is the significance of the wire gauge difference between the main part and substitutes?

A: The original 1-1546216-2 accepts 15-17 AWG wire. The 1-282836-2 accepts 16-30 AWG, and the ESLM12100 accepts 14-30 AWG. Both substitutes encompass the original specification range, allowing use with the same wire sizes. The extended ranges provide flexibility for applications requiring different wire gauges.

Q: Does the color difference between parts affect substitution?

A: No. Housing color (gray, green, or black) is a cosmetic attribute and does not affect electrical or mechanical function. Color selection is independent of substitution compatibility.

Q: What is the impact of the torque specification difference in the ESLM12100?

A: The ESLM12100 specifies 0.5 Nm (4.4 Lb-In) screw torque compared to 0.68 Nm (6 Lb-In) for the original part. Assembly procedures must be adjusted accordingly to prevent over-torquing or under-torquing of wire termination screws.

Q: Are both substitutes RoHS compliant?

A: Yes. The 1-282836-2 is ROHS3 compliant, and the ESLM12100 is RoHS compliant. Both meet current regulatory requirements for restricted substance elimination.

Q: What packaging options are available for these substitutes?

A: The 1-282836-2 is supplied in bulk packaging, while the ESLM12100 is supplied in tray packaging. Packaging selection depends on inventory management and handling requirements for production environments.

Q: Can the ESLM12100 be used in applications with elevated temperature requirements?

A: Yes. The ESLM12100 operates across -40°C ~ 110°C, providing a 5°C higher maximum temperature rating compared to the original 1-1546216-2 (-40°C ~ 105°C). This extended range is suitable for applications requiring operation at elevated ambient or component temperatures.
