Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 282816-4 with the active equivalent 1776162-4 is based on strict electrical and mechanical parameter matching within the terminal block header category. Both components share identical specifications across all critical substitution criteria:

Matching Parameters:

• 4-position configuration with 0.394" (10.00mm) pitch
• 90° right-angle header orientation
• Male pins with full 4-side shrouding
• Through-hole solder termination
• 15 A UL current rating and 600 V UL voltage rating
• Operating temperature range of -40°C to 110°C
• UL94 V-0 flammability classification
• Copper alloy contacts with tin mating finish
• Identical contact tail length (0.138" / 3.50mm) and insulation height (0.329" / 8.36mm)
• Polyamide nylon housing material

The primary distinction between these components is product status and compliance certification. The 282816-4 is obsolete, while the 1776162-4 maintains active production status with current RoHS and REACH compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The 1776162-4 serves as the direct functional equivalent to the obsolete 282816-4 for all electrical and mechanical applications. Selection of the 1776162-4 is supported by the following engineering factors:

Product Status: The 1776162-4 maintains active production status, ensuring continued availability and supply chain stability. The 282816-4 is classified as obsolete and subject to discontinuation without notice.

Compliance Certification: The 1776162-4 carries current RoHS compliance documentation and REACH affected status, meeting contemporary regulatory requirements for component procurement in regulated industries. The 282816-4 lists REACH status as vendor undefined, limiting its applicability in new designs subject to REACH compliance mandates.

Electrical and Mechanical Compatibility: Both components are identical across all critical parameters governing terminal block header functionality, including current rating, voltage rating, pitch, orientation, termination method, and operating temperature range. Direct substitution requires no circuit design modifications or PCB layout adjustments.

Physical Compatibility: Identical contact tail length, insulation height, and through-hole mounting specifications ensure mechanical interchangeability without requiring changes to printed circuit board footprints or assembly procedures.

The only non-functional difference between these components is housing color (green versus black), which does not affect electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the 1776162-4 be used as a direct replacement for the 282816-4 in existing designs?

A: Yes. The 1776162-4 is electrically and mechanically identical to the 282816-4 across all parameters that determine terminal block header functionality. No design modifications are required for substitution.

Q: What is the significance of the product status difference between these components?

A: The 282816-4 is classified as obsolete, indicating that TE Connectivity AMP Connectors has discontinued production and will not guarantee future availability. The 1776162-4 maintains active production status, ensuring reliable supply for current and future procurement needs.

Q: Are there any compliance differences between these two components?

A: The 1776162-4 carries current RoHS compliance certification and REACH affected status, meeting modern regulatory requirements. The 282816-4 lists REACH status as vendor undefined. For applications subject to REACH compliance mandates, the 1776162-4 is the appropriate selection.

Q: Does the color difference between the 282816-4 (green) and 1776162-4 (black) affect functionality?

A: No. Housing color is a cosmetic attribute and does not affect electrical performance, current rating, voltage rating, temperature range, or mechanical compatibility. Color selection is based on design preference or inventory availability.

Q: Are the housing materials identical between these components?

A: Both components use polyamide nylon housing material. The 282816-4 specifies PA66 (Nylon 6/6), while the 1776162-4 specifies PA (Nylon). Both materials meet the UL94 V-0 flammability requirement and are functionally equivalent for this application.

Q: What are the key parameters that determine whether a terminal block header can substitute for the 282816-4?

A: Substitution is determined by matching the following parameters: 4-position configuration, 0.394" (10.00mm) pitch, 90° right-angle orientation, male pins with 4-side shrouding, through-hole solder termination, 15 A UL current rating, 600 V UL voltage rating, -40°C to 110°C operating temperature range, and identical contact tail and insulation height dimensions.

Q: Is the 1776162-4 available in inventory?

A: According to current data, 988 pieces of the 1776162-4 are available as new original stock.
