LTM-180 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-180 is an active LED standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This component provides mechanical support and positioning for vertical LED mounting with a 0.180" (4.57mm) standoff height. The part is constructed from crystalline polymer material in black color and is ROHS3 compliant with MSL 1 rating.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTM-180 are qualified based on the following critical parameters:

LED Type Compatibility: Both main and substitute parts must support T1 and T1 3/4 LED form factors.

Standoff Height Tolerance: The substitute part height of 0.177" (4.50mm) falls within acceptable mechanical tolerance for LED standoff applications, representing a 0.003" (0.07mm) variance from the primary part specification.

Color Specification: Both parts are black, ensuring visual and mechanical consistency in assembly.

Material Classification: While the main part uses crystalline polymer and the substitute uses nylon, both materials are thermoplastic polymers suitable for LED standoff applications and meet UL94 flammability standards.

Regulatory Compliance: Both parts maintain ROHS3 compliance and share identical ECCN and HTSUS classifications, confirming equivalence for export and tariff purposes.

Packaging Format: Both parts are supplied in bag packaging, supporting identical handling and storage procedures.

Parameter Comparison

Engineering Selection Recommendations

Both the LTM-180 and 705820045 are active products with confirmed ROHS3 compliance and identical regulatory classifications. Selection between these parts is based on the following engineering criteria:

Primary Part (LTM-180): Use when crystalline polymer material properties are specified in design documentation or when exact 0.180" height is required.

Substitute Part (705820045): Use when nylon 66 material is acceptable and the 0.177" standoff height variance is within assembly tolerances. This part offers higher inventory availability (6850 pcs vs. 902 pcs).

Both parts support identical LED form factors (T1, T1 3/4) and maintain equivalent mechanical and electrical performance characteristics for standard LED mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 705820045 be used as a direct replacement for the LTM-180?

A: Yes, the 705820045 qualifies as a parametric equivalent. Both parts support T1 and T1 3/4 LEDs, are black in color, maintain ROHS3 compliance, and share identical ECCN and HTSUS classifications. The 0.003" height difference (0.180" vs. 0.177") is within standard mechanical tolerances for LED standoff applications.

Q: What is the material difference between these parts?

A: The LTM-180 uses crystalline polymer, while the 705820045 uses nylon 66. Both are thermoplastic materials suitable for LED standoff applications. The nylon 66 variant includes UL94 V-2 flammability rating.

Q: Are there any compliance differences?

A: No. Both parts are ROHS3 compliant, share the same ECCN (EAR99) and HTSUS (3926.90.9985) classifications, and are classified as active products.

Q: What packaging format is used for both parts?

A: Both the LTM-180 and 705820045 are supplied in bag packaging, supporting identical receiving, storage, and handling procedures.

Q: Which part should be selected for new designs?

A: Selection depends on material specification requirements and availability. Both parts are active and suitable for new applications. Verify that the 0.177" standoff height of the 705820045 is acceptable within your assembly tolerances if substituting from the LTM-180.
