LTM-380 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-380 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from crystalline polymer material in black color with a 0.380" (9.65mm) 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, making it suitable for current production environments. Equivalent substitute parts are identified based on matching LED form factor, color specification, material compatibility, and dimensional tolerance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTM-380 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Matching Criteria:

• LED form factor (T1, T1 3/4 compatibility)
• Color specification (Black)
• Length tolerance (within acceptable assembly clearance range)
• Material classification (polymer-based standoff materials)
• RoHS3 compliance status
• Regulatory classification (ECCN and HTSUS alignment)

The identified substitutes (705820095 and 705820100) are manufactured by Würth Elektronik and maintain the same LED type designation and black color specification. Both substitutes are constructed from Nylon material, which is functionally equivalent to crystalline polymer for LED standoff applications. Length variations (0.374" and 0.394" respectively) fall within acceptable tolerance ranges for standard PCB assembly processes where the LTM-380's 0.380" dimension is specified.

Parameter Comparison

Engineering Selection Recommendations

LTM-380 (Primary Part): Use when original specification calls for crystalline polymer material and 0.380" length dimension. Maintains unlimited moisture sensitivity rating (MSL 1) suitable for standard storage and handling conditions.

705820095 (Würth Elektronik): Suitable for applications where 0.374" (9.50mm) length is acceptable within assembly tolerance stack-up. Nylon material provides equivalent mechanical performance for LED standoff function. ROHS3 compliance and EAR99 classification match regulatory requirements. Nylon material exhibits MSL Not Applicable, indicating superior moisture resistance characteristics.

705820100 (Würth Elektronik): Suitable for applications where 0.394" (10.00mm) length is acceptable within assembly tolerance stack-up. Nylon construction provides equivalent mechanical performance. ROHS3 compliance and EAR99 classification match regulatory requirements. Nylon material exhibits MSL Not Applicable, indicating superior moisture resistance characteristics.

Selection between substitute parts depends on PCB assembly design tolerance requirements. The 0.020" (0.50mm) length difference between 705820095 and 705820100 accommodates different LED mounting height specifications.

Frequently Asked Questions (FAQ)

Q: Can 705820095 or 705820100 be used as direct replacements for LTM-380?

A: Yes, both Würth Elektronik parts are parametric equivalents. They share identical LED type (T1, T1 3/4), color (Black), and regulatory compliance (ROHS3, EAR99). Length differences (±0.006" to +0.014" from nominal 0.380") are within standard PCB assembly tolerances. Material substitution from crystalline polymer to nylon does not affect LED standoff functionality.

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

A: The LTM-380 specifies 0.380" (9.65mm), while 705820095 is 0.374" (9.50mm) and 705820100 is 0.394" (10.00mm). These variations accommodate different PCB design requirements for LED mounting height. Selection depends on the specific assembly design tolerance and LED lens clearance requirements. All three lengths are within acceptable ranges for T1/T1 3/4 LED standoff applications.

Q: Are there material compatibility concerns when substituting crystalline polymer with nylon?

A: No. Both materials are polymer-based standoff materials suitable for LED mounting applications. Nylon exhibits superior moisture resistance (MSL Not Applicable versus MSL 1), making it suitable for standard manufacturing and storage environments. Both materials provide equivalent mechanical support and electrical isolation for LED positioning.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. LTM-380, 705820095, and 705820100 all carry ROHS3 compliance status and EAR99 export classification. All three share the same HTSUS code (3926.90.9985), confirming equivalent tariff classification for import/export purposes.

Q: What inventory considerations apply to these substitutes?

A: LTM-380 has 822 pcs in stock. 705820095 has 1578 pcs in stock. 705820100 has 6138 pcs in stock. Availability of substitute parts may influence selection when LTM-380 stock is limited.
