LTM-410 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-410 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from crystalline polymer material in black color with a 0.410" (10.41mm) length. This component is designed for vertical mounting applications requiring precise LED positioning and alignment in electronic assemblies. The part maintains Active product status and is ROHS3 compliant with MSL Level 1 rating, indicating unlimited moisture tolerance. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining functional and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the LTM-410 is based on strict parameter alignment across the following critical dimensions:

LED Type Compatibility: All substitute parts must support T1 and T1 3/4 LED form factors to ensure mechanical fit within the standoff cavity.

Length Tolerance: Substitute parts are grouped by length proximity to the primary specification of 0.410" (10.41mm). Acceptable substitutes fall within the range of 0.394" to 0.413", representing dimensional variations that accommodate standard assembly tolerances and PCB layout flexibility.

Color Specification: All identified substitutes maintain black color consistency with the primary part, ensuring visual uniformity in assembled products.

Material Classification: While the primary part uses crystalline polymer, substitute parts employ nylon material. Both materials are classified as engineering polymers suitable for LED standoff applications and maintain equivalent mechanical performance characteristics within the specified parameter set.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance, meeting the same environmental and hazardous substance restrictions as the primary part.

Packaging: All parts are supplied in bag packaging format, maintaining consistency in handling and inventory management.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (LTM-410): Select the LTM-410 when crystalline polymer material properties are specified in the design documentation and inventory availability meets project lead time requirements. This part maintains Active status with established supply chain continuity.

Substitute Selection (705820100): The 705820100 offers the shortest length at 0.394" (10.00mm) and highest inventory availability at 6138 pieces. This substitute is suitable for applications where reduced standoff height is acceptable within assembly tolerances. Material composition changes from crystalline polymer to nylon; both materials are engineering polymers meeting ROHS3 compliance.

Substitute Selection (705820105): The 705820105 provides the closest length match at 0.413" (10.50mm), representing a 0.003" (0.09mm) variance from the primary specification. This substitute offers optimal dimensional compatibility when assembly height precision is critical. Inventory availability is 2331 pieces. Material composition is nylon, consistent with the 705820100 substitute.

Compliance Verification: All parts maintain ROHS3 compliance and are classified under identical HTSUS code 3926.90.9985, confirming regulatory and tariff classification equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 705820100 and 705820105 be used interchangeably with the LTM-410?

A: Both Würth Elektronik substitutes support the same T1/T1 3/4 LED form factor and maintain black color and ROHS3 compliance. Length differences of 0.016" (0.41mm) and 0.003" (0.09mm) respectively must be evaluated against specific assembly height requirements and PCB layout constraints. Material change from crystalline polymer to nylon requires confirmation that design specifications do not mandate the original polymer composition.

Q: What is the significance of the length variation between substitute parts?

A: The LTM-410 specifies 0.410" (10.41mm) length. The 705820100 measures 0.394" (10.00mm), representing a 0.016" reduction, while the 705820105 measures 0.413" (10.50mm), representing a 0.003" increase. These variations fall within standard manufacturing tolerances for LED standoff components. Assembly compatibility depends on PCB design specifications and available clearance above the LED mounting surface.

Q: Does material substitution from crystalline polymer to nylon affect performance?

A: Both crystalline polymer and nylon are engineering polymers used in LED standoff applications. The provided parameter set does not include thermal conductivity, mechanical strength, or chemical resistance specifications that would differentiate performance. Material selection should be confirmed against design documentation if specific polymer properties are required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The LTM-410, 705820100, and 705820105 all maintain ROHS3 compliance status, confirming equivalent regulatory classification and hazardous substance restrictions.

Q: What inventory considerations apply to substitute selection?

A: The LTM-410 has 1079 pieces in stock. The 705820100 offers significantly higher availability at 6138 pieces, while the 705820105 provides 2331 pieces. Substitute selection based on inventory availability is appropriate when lead time or supply chain continuity is a project constraint.

Q: Are packaging formats identical across all parts?

A: Yes. The LTM-410, 705820100, and 705820105 are all supplied in bag packaging, maintaining consistency in handling, storage, and inventory management procedures.
