TE Connectivity AMP Connectors 282824-3 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 282824-3 is a 3-position terminal block header with male pins, shrouded on 2 sides, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This component is part of the Buchanan series and is classified as Active product status. The part operates within a voltage range of 300 V UL and supports a current rating of 15 A UL, with an operating temperature range of -40°C to 110°C. Identification of equivalent and substitute parts becomes necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative configurations that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 282824-3 terminal block header is determined by alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Voltage rating: 300 V UL minimum
• Current rating: 15 A UL minimum
• Number of positions: 3 positions required
• Contact material: Copper alloy construction

Mechanical Compatibility Parameters:

• Header orientation: Vertical configuration
• Pitch spacing: 0.200" (5.08mm) nominal or equivalent metric conversion (0.197" / 5.00mm acceptable within tolerance)
• Type configuration: Male pins with shrouding
• Mounting method: Through-hole or solder termination

Compliance and Environmental Parameters:

• Operating temperature range: Minimum -40°C to 110°C or equivalent
• RoHS compliance status: RoHS Compliant or ROHS3 Compliant
• Moisture sensitivity level: MSL 1 (Unlimited)
• Housing material: Polyamide or Nylon construction

The substitute part EDSTL955/3 from On Shore Technology Inc. meets these substitution criteria with pitch spacing of 0.197" (5.00mm), which represents a metric equivalent to the 0.200" (5.08mm) specification within standard engineering tolerances for terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TE Connectivity 282824-3

The TE Connectivity 282824-3 maintains Active product status with established supply availability (699 pieces in stock). This component carries full RoHS Compliance certification and operates across the extended temperature range of -40°C to 110°C. The through-hole mounting configuration with 2-side shrouding provides standard mechanical retention. Selection of this part is appropriate for applications requiring the specified temperature extremes and established supply chain continuity.

Substitute Part: On Shore Technology EDSTL955/3

The EDSTL955/3 qualifies as a functional substitute based on electrical parameter alignment (300 V, 3-position configuration) and mechanical compatibility (vertical orientation, 5.00mm metric pitch equivalent). This component carries ROHS3 Compliance certification, indicating current regulatory alignment. The enhanced 4-side shrouding provides additional mechanical protection compared to the 2-side configuration of the primary part. The operating temperature range of -30°C to 105°C is acceptable for applications not requiring the -40°C lower temperature extreme. The solder mounting termination differs from the through-hole configuration of the primary part, requiring PCB design accommodation. Inventory availability is higher (1138 pieces in stock), supporting supply chain flexibility.

Selection Criteria:

• Use TE Connectivity 282824-3 when through-hole mounting is required and extended low-temperature operation (-40°C) is specified.
• Use On Shore Technology EDSTL955/3 when solder termination is acceptable, 4-side shrouding provides design advantage, and operating temperature minimum of -30°C satisfies application requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 282824-3 and EDSTL955/3 terminal block headers?

A: The primary differences are mounting method (through-hole versus solder), shrouding configuration (2-side versus 4-side), and pitch specification (0.200" versus 0.197"). Both components maintain 3-position configuration, 300 V voltage rating, and vertical orientation. The pitch difference represents metric versus imperial specification equivalence within standard engineering tolerances.

Q: Are the pitch specifications 0.200" (5.08mm) and 0.197" (5.00mm) interchangeable?

A: The 0.197" (5.00mm) pitch represents the metric standard equivalent to the 0.200" (5.08mm) imperial specification. These specifications are functionally equivalent for terminal block applications and fall within acceptable tolerance ranges for connector mating and PCB layout design.

Q: What is the significance of the shrouding difference between 2-side and 4-side configurations?

A: The 2-side shrouding on the 282824-3 provides lateral protection during mating operations. The 4-side shrouding on the EDSTL955/3 provides enhanced protection on all sides, reducing risk of accidental contact with energized pins. Selection depends on application-specific safety and accessibility requirements.

Q: Can the EDSTL955/3 be used in applications requiring -40°C operation?

A: The EDSTL955/3 operates to a minimum of -30°C. Applications requiring -40°C operation must use the TE Connectivity 282824-3, which is rated to -40°C minimum.

Q: What mounting method differences exist between these components?

A: The 282824-3 uses through-hole mounting with solder termination, requiring drilled PCB holes for pin insertion. The EDSTL955/3 uses direct solder termination without through-hole requirement, accommodating surface-mount or alternative PCB design approaches.

Q: Are both components RoHS compliant?

A: Yes. The 282824-3 carries RoHS Compliance certification. The EDSTL955/3 carries ROHS3 Compliance certification, representing current regulatory alignment. Both satisfy RoHS requirements for restricted substance elimination.

Q: What is the inventory status for each component?

A: The TE Connectivity 282824-3 has 699 pieces in stock. The On Shore Technology EDSTL955/3 has 1138 pieces in stock, providing greater supply availability for urgent procurement requirements.

Q: Do these components have different contact tail lengths?

A: Yes. The 282824-3 has a contact tail length of 0.138" (3.50mm), while the EDSTL955/3 has 0.154" (3.90mm). This variation requires consideration in PCB design, particularly for solder joint formation and mechanical clearance.

Q: What is the significance of the insulation height difference?

A: The 282824-3 has an insulation height of 0.472" (12.00mm), while the EDSTL955/3 has 0.154" (3.90mm). This substantial difference reflects different mechanical designs and mounting approaches. The through-hole configuration of the 282824-3 requires greater insulation height for structural integrity.
