• 0.197" (5.00mm) pitch spacing
• Vertical header orientation
• Male pins, unshrouded configuration
• Through-hole mounting
• Solder termination capability
• 300 V UL voltage rating minimum
• Tin contact mating finish
• UL94 V-0 flammability rating
• ROHS3 compliance

Substitute Classification:

Direct Equivalent: Part 1-1546931-2 (TE Connectivity) matches all critical electrical and mechanical parameters with identical specifications. Housing color differs (Black vs. Green) but does not affect functional compatibility.

Similar Equivalent: Parts 1933286 (Phoenix Contact) and OSTOP120000 (On Shore Technology Inc.) satisfy core dimensional and electrical requirements with noted parameter variations documented in the comparison table.

Parameter Comparison

Engineering Selection Recommendations

1-1546931-2 (TE Connectivity - Direct Equivalent)

This part is classified as a direct equivalent substitute. It maintains identical electrical ratings (12 A UL, 300 V UL), mechanical dimensions (12 positions, 5.00mm pitch, 0.138" tail length), and compliance certifications (ROHS3, UL94 V-0, MSL 1). The only difference is housing color (Black vs. Green), which does not affect electrical or mechanical function. Both parts are Active status with comparable inventory availability (960 vs. 978 units). This substitute is suitable for direct replacement in all applications.

1933286 (Phoenix Contact - Similar Equivalent)

This part satisfies core dimensional and electrical requirements with the following considerations: It maintains 12 positions at 5.00mm pitch with identical contact tail length and insulation height. Electrical ratings exceed the main part specification (16 A UL vs. 12 A UL; 400 V IEC vs. unspecified IEC). Material flammability rating is UL94 V-0 compliant. ROHS3 compliance and MSL 1 rating are confirmed. The part is Active status with highest inventory availability (2260 units). Housing material is specified as Polyamide (PA), Nylon. This substitute is suitable for applications where higher current capacity is acceptable.

OSTOP120000 (On Shore Technology Inc. - Similar Equivalent)

This part meets dimensional specifications (12 positions, 5.00mm pitch, 0.138" tail length) and voltage rating (300 V UL). Key differences include: Insulation height is 0.138" (3.50mm) versus 0.079" (2.00mm) on the main part, representing a significant dimensional variance. Material flammability rating is not specified. Current rating is not specified. Housing material is listed as Brass. Termination style is not specified. ROHS3 compliance and MSL 1 rating are confirmed. The part is Active status with 1113 units in inventory. This substitute is suitable only for applications where the increased insulation height does not create mechanical interference and where flammability rating specification is not required.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and Active product status, supporting long-term supply chain viability.

Frequently Asked Questions (FAQ)

Q: Can 1-1546931-2 be used as a direct replacement for 1-282832-2?

A: Yes. Both parts are TE Connectivity Buchanan series components with identical electrical ratings (12 A UL, 300 V UL), mechanical dimensions (12 positions, 5.00mm pitch, 0.138" contact tail length, 0.079" insulation height), and compliance certifications (ROHS3, UL94 V-0, MSL 1). Housing color difference (Black vs. Green) does not affect functional compatibility.

Q: What are the key differences between the Phoenix Contact 1933286 and the main part 1-282832-2?

A: The 1933286 maintains matching pitch (5.00mm), position count (12), contact tail length (0.138"), and insulation height (0.079"). Electrical differences include higher UL current rating (16 A vs. 12 A) and specified IEC ratings (12 A, 400 V) not provided for the main part. Both are UL94 V-0 compliant and ROHS3 certified. The 1933286 belongs to the Phoenix Contact COMBICON PST series rather than Buchanan.

Q: Why does the OSTOP120000 have a different insulation height?

A: The OSTOP120000 specifies 0.138" (3.50mm) insulation height compared to 0.079" (2.00mm) on the main part. This represents a dimensional difference that may affect mechanical fit in applications with height constraints. Verification of mechanical clearance is necessary before substitution in space-limited designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (1-1546931-2, 1933286, and OSTOP120000) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level rating, matching the main part 1-282832-2 compliance profile.

Q: Which substitute part has the highest current rating?

A: The Phoenix Contact 1933286 has the highest UL current rating at 16 A, compared to 12 A for the main part 1-282832-2 and 1-1546931-2. The OSTOP120000 does not specify a current rating.

Q: Can the OSTOP120000 be used in all applications where 1-282832-2 is specified?

A: The OSTOP120000 meets voltage (300 V UL) and pitch (5.00mm) requirements but differs in insulation height (0.138" vs. 0.079"). Material flammability rating and current rating are not specified for the OSTOP120000. Substitution is limited to applications where increased insulation height does not create mechanical interference and where flammability certification is not a design requirement.

Q: What is the inventory status for each part?

A: Current inventory levels are: 1-282832-2 (978 units), 1-1546931-2 (960 units), 1933286 (2260 units), and OSTOP120000 (1113 units). All parts are Active status with available stock.

Q: Do all substitute parts use tin contact mating finish?

A: Yes. All substitute parts (1-1546931-2, 1933286, and OSTOP120000) specify tin contact mating finish, matching the main part 1-282832-2.

Q: What is the operating temperature range for substitute parts?

A: The main part 1-282832-2 specifies -40°C to 110°C operating temperature. Operating temperature is not specified for substitute parts 1-1546931-2, 1933286, and OSTOP120000 in the provided data.
