Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-1546220-2 terminal block is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current rating (17.5 A), voltage rating (300 V), and wire gauge acceptance (12-30 AWG) must remain identical.

Mechanical Compatibility: Position count (12), pitch spacing (0.200"/5.08mm), mating angle (35°), mounting method (through-hole), and termination type (screw-based rising cage clamp) must be preserved.

Material and Construction: Housing material (Polyamide PA66/Nylon 6/6), contact plating (Brass - Tin Plated), clamp plating (Brass - Nickel Plated), and screw specifications (M3 thread, 0.79 Nm torque) must match.

Series Designation: Both parts belong to the TE Connectivity Buchanan series, ensuring design consistency.

The substitute part 1-282847-2 meets all these criteria and is classified as active product status, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The 1-282847-2 terminal block is the direct functional equivalent of the obsolete 1-1546220-2. Both components are manufactured by TE Connectivity within the Buchanan series and share identical electrical, mechanical, and material specifications across all critical parameters.

Product Status Advantage: The 1-282847-2 is classified as active product status, ensuring continued availability and manufacturing support. The 1-1546220-2 is obsolete and subject to discontinuation.

Regulatory Compliance: Both parts maintain ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS classifications, supporting equivalent regulatory and export requirements.

Moisture Sensitivity: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

REACH Status Difference: The substitute part 1-282847-2 is REACH Affected, whereas the main part shows Vendor Undefined status. This distinction reflects current regulatory documentation standards and does not affect functional compatibility.

Cosmetic Variation: The housing color differs (gray versus green), representing a cosmetic distinction with no impact on electrical or mechanical performance.

Packaging Consideration: The substitute is supplied in bulk packaging format, which may differ from the original part's packaging specification. Procurement should confirm packaging requirements for assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the 1-282847-2 be used as a direct replacement for the 1-1546220-2 in existing PCB designs?

A: Yes. The 1-282847-2 is electrically and mechanically identical to the 1-1546220-2 across all functional parameters. Both components feature identical pitch spacing (5.08mm), position count (12), mating angle (35°), current/voltage ratings (17.5 A/300 V), wire gauge acceptance (12-30 AWG), and termination method (screw-based rising cage clamp). No PCB layout modifications are required.

Q: Does the color difference between gray (1-1546220-2) and green (1-282847-2) affect performance?

A: No. Housing color is a cosmetic attribute only and does not affect electrical performance, mechanical fit, or thermal characteristics. Both colors represent the same polyamide (PA66/Nylon 6/6) material composition.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 1-1546220-2 is classified as obsolete, indicating TE Connectivity has discontinued manufacturing and will not guarantee future availability. The 1-282847-2 is active product status, confirming ongoing manufacturing support and long-term procurement availability. For new designs or ongoing production, the active substitute is the appropriate selection.

Q: Are the screw torque specifications identical between both parts?

A: Yes. Both the 1-1546220-2 and 1-282847-2 require identical screw torque of 0.79 Nm (7.0 Lb-In) with M3 thread specification. Assembly procedures and torque tools remain unchanged.

Q: How does the packaging difference (unspecified vs. bulk) affect component selection?

A: Packaging format affects procurement and assembly logistics but not component functionality. The 1-282847-2 is supplied in bulk packaging. Procurement departments should confirm that bulk packaging meets assembly line requirements and storage protocols. Functional compatibility remains unaffected by packaging format.

Q: Are both parts compliant with RoHS3 requirements?

A: Yes. Both the 1-1546220-2 and 1-282847-2 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions. Both carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What does the REACH Affected status on the substitute part indicate?

A: REACH Affected status on the 1-282847-2 indicates the component is subject to European REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. This reflects current regulatory documentation standards and does not impact functional compatibility or performance characteristics. The main part shows Vendor Undefined status, which represents older documentation practices.

Q: Can wire gauge specifications be mixed between the two parts in the same application?

A: Both parts accept identical wire gauge ranges (12-30 AWG) and carry the same current rating (17.5 A). Wire gauge selection is determined by application current requirements, not by part selection. Either component supports the full 12-30 AWG range without restriction.
