Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1776141-2 is based on strict electrical and mechanical parameter alignment. The following criteria determine functional equivalence:

Critical Matching Parameters:

• Number of Positions: 2
• Pitch: 0.200" (5.08mm)
• Header Orientation: 90°, Right Angle
• Mounting Type: Through Hole
• Termination Style: Solder
• Current Rating (UL): 15 A
• Voltage Rating (UL): 300 V
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Shrouding configuration (2-side vs. 4-side)
• Housing material composition (Polyamide vs. Polybutylene Terephthalate)
• Contact material (Copper Alloy vs. Brass)
• Operating temperature range (within acceptable limits)
• Insulation height (minor dimensional variance)
• Product status (Active substitute for Obsolete main part)

The ELFH02210 from Amphenol PCD meets all critical electrical and mechanical parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ELFH02210 from Amphenol PCD is a direct functional substitute for the obsolete TE Connectivity 1776141-2. Selection of this substitute is supported by the following engineering factors:

Electrical Compatibility: Both components share identical current (15 A UL) and voltage (300 V UL) ratings, ensuring equivalent performance in circuit applications.

Mechanical Compatibility: Pitch (0.200"/5.08mm), orientation (90° right angle), and mounting type (through-hole solder) are identical, enabling direct board-level substitution without layout modification.

Thermal Performance: The ELFH02210 operating range of -40°C to 105°C encompasses the majority of the 1776141-2 range (-40°C to 110°C), with the 5°C difference at the upper limit presenting negligible impact for most industrial applications.

Compliance Enhancement: The ELFH02210 carries ROHS3 compliance certification, whereas the 1776141-2 status is not applicable. This represents an improvement in regulatory alignment for new designs and procurement.

Product Status: The transition from obsolete (1776141-2) to active (ELFH02210) ensures long-term availability and supply chain continuity.

Shrouding Configuration: The ELFH02210 features 4-side shrouding compared to the 2-side shrouding of the 1776141-2, providing enhanced mechanical protection and improved board-level stability.

Frequently Asked Questions (FAQ)

Q: Can the ELFH02210 be used as a direct replacement for the 1776141-2 in existing designs?

A: Yes. The ELFH02210 meets all critical electrical and mechanical parameters: 2 positions, 0.200" (5.08mm) pitch, 90° right angle orientation, 15 A UL current rating, 300 V UL voltage rating, and through-hole solder termination. Board layout and schematic compatibility are maintained.

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

A: The 1776141-2 features shrouding on 2 sides, while the ELFH02210 features shrouding on 4 sides. Four-side shrouding provides additional mechanical protection and lateral stability during board assembly and operation. This difference does not affect electrical performance or pin pitch compatibility.

Q: Are there any temperature rating concerns when substituting the ELFH02210?

A: The ELFH02210 operates from -40°C to 105°C, compared to the 1776141-2 range of -40°C to 110°C. The 5°C difference at the upper limit is within acceptable tolerance for most industrial and commercial applications. Applications requiring operation above 105°C require specific thermal analysis.

Q: What is the significance of the RoHS3 compliance on the ELFH02210?

A: RoHS3 compliance indicates adherence to Restriction of Hazardous Substances regulations, restricting the use of specific hazardous materials. The 1776141-2 lists RoHS status as not applicable. Selecting the ELFH02210 ensures regulatory alignment for new designs and procurement in regions with RoHS requirements.

Q: Are the contact materials interchangeable between the two parts?

A: The 1776141-2 uses Copper Alloy contacts, while the ELFH02210 uses Brass contacts. Both materials provide equivalent electrical conductivity and tin mating finish. The contact material difference does not affect functional performance in standard applications.

Q: What is the housing material difference, and does it affect performance?

A: The 1776141-2 uses Polyamide (PA) Nylon housing, while the ELFH02210 uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability ratings and provide equivalent mechanical and thermal performance for the specified operating range.

Q: Is the ELFH02210 available in the same packaging as the 1776141-2?

A: The 1776141-2 packaging is listed as unspecified in the provided data. The ELFH02210 is available in bulk packaging. Confirm packaging requirements with your procurement specification before finalizing the substitution.

Q: Can the ELFH02210 be used in high-reliability or aerospace applications?

A: Substitution decisions for high-reliability, aerospace, or military applications require additional qualification beyond electrical and mechanical parameter matching. Consult application-specific standards and manufacturer qualification documentation.
