LTM-720 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-720 is an active LED standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This component features a black crystalline polymer construction with a 0.720" (18.29mm) vertical mounting height and is supplied in bag packaging. The part maintains ROHS3 compliance and MSL Level 1 rating, making it suitable for standard electronic assembly environments. Substitute parts are identified when equivalent functional performance can be achieved through alternative manufacturers while maintaining critical dimensional and electrical specifications.

Substitute Part Grouping Explanation

Substitution of the LTM-720 is determined by strict adherence to the following critical parameters:

LED Type Compatibility: Both the main part and substitute must accommodate T1 and T1 3/4 LED form factors without modification.

Mounting Height Tolerance: The standoff height must remain within the specified range. The LTM-720 specifies 0.720" (18.29mm), while the substitute part 705820180 provides 0.709" (18.00mm). This 0.011" (0.29mm) variance falls within standard mechanical tolerances for LED standoff applications and does not compromise circuit board layout or LED alignment.

Color Specification: Both parts are black, ensuring visual consistency in assembled products.

Material Classification: The LTM-720 uses crystalline polymer; the substitute uses nylon. Both materials are polymer-based with comparable mechanical properties and thermal stability for LED standoff applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and share identical ECCN (EAR99) and HTSUS (3926.90.9985) classifications, confirming equivalent regulatory status.

Packaging Format: Both parts are supplied in bag packaging, maintaining supply chain compatibility.

Engineering Selection Recommendations

Primary Selection: LTM-720 (Bivar Inc.) is the specified component and should be used when available and inventory permits.

Substitute Selection: Part 705820180 (Würth Elektronik) is a valid substitute when LTM-720 is unavailable. Selection is based on the following engineering criteria:

Both parts maintain active product status, confirming ongoing manufacturer support and supply chain availability. ROHS3 compliance is identical, ensuring regulatory equivalence for all markets requiring lead-free components. The 0.011" (0.29mm) height difference between parts is within standard mechanical tolerances for LED standoff applications and does not introduce functional risk in typical circuit board designs. Material substitution from crystalline polymer to nylon does not compromise performance, as both materials provide equivalent mechanical strength and thermal stability for LED mounting applications. Identical ECCN and HTSUS classifications confirm that substitution does not alter export control or tariff status.

The substitute part carries no MSL restriction, which represents an advantage in storage and handling compared to the MSL Level 1 rating of the primary part.

Frequently Asked Questions (FAQ)

Q: Can part 705820180 be used as a direct replacement for LTM-720 in production?

A: Yes. Both parts meet the critical functional parameters: T1/T1 3/4 LED compatibility, black color, ROHS3 compliance, and identical regulatory classifications. The 0.011" height variance is within standard mechanical tolerances for LED standoff applications.

Q: What is the significance of the height difference between 0.720" and 0.709"?

A: The 0.29mm difference represents approximately 1.5% variance and falls within standard mechanical tolerances for LED standoff components. This variance does not affect LED alignment, circuit board layout, or electrical performance in typical applications.

Q: Why does the substitute part show "Not Applicable" for Moisture Sensitivity Level?

A: Würth Elektronik's nylon material does not require MSL classification under standard handling conditions. This indicates the substitute part has no moisture sensitivity restrictions, which is equivalent to or better than the MSL Level 1 rating of the primary part.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical ROHS3 compliance status, ECCN classification (EAR99), and HTSUS code (3926.90.9985). Substitution does not alter regulatory or export control requirements.

Q: What is the difference between crystalline polymer and nylon materials in this application?

A: Both materials are polymer-based with comparable mechanical properties and thermal stability suitable for LED standoff applications. The material difference does not introduce functional risk or performance degradation in standard electronic assembly environments.

Q: Is inventory availability a factor in substitution decisions?

A: Yes. The LTM-720 has 990 pieces in stock, while 705820180 has 1092 pieces in stock. Substitution may be considered when primary part inventory is depleted or lead times are critical.

Q: Can these parts be used interchangeably in existing designs without design review?

A: Substitution is based on equivalent functional parameters. However, design documentation should be updated to reflect any part number changes in production records and bill of materials.
