Würth Elektronik 705820150 LED Standoff Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 705820150 is an active T1/T1 3/4 LED standoff manufactured from Nylon 66 material with UL94 V-2 flame rating. This component is designed for vertical LED mounting applications requiring mechanical support and electrical isolation. The part is ROHS3 compliant and REACH unaffected, making it suitable for current electronics manufacturing standards. Equivalent and substitute parts are identified based on matching LED form factor, material compatibility, mechanical dimensions, and regulatory compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 705820150 is determined by the following parameters:

• LED Form Factor: All substitutes must support T1 and T1 3/4 LED types
• Material Classification: Nylon-based or equivalent crystalline polymer materials with UL94 V-2 or equivalent flame rating
• Color: Black
• Length Tolerance: Mechanical height within the range of 0.571" to 0.620" (14.50mm to 15.75mm)
• Regulatory Compliance: ROHS3 compliant and REACH unaffected status required
• Product Status: Active status only

The three identified substitutes meet these criteria with variations in length dimension and material composition. All parts are manufactured by established component suppliers with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

705820145 (Würth Elektronik): Shortest available option at 0.571" (14.50mm). Suitable for applications requiring reduced standoff height. Identical material composition and flame rating to the main part. ROHS3 compliant with active product status.

705820155 (Würth Elektronik): Mid-range length at 0.610" (15.50mm). Provides minimal height increase from the main part specification. Maintains identical material and regulatory compliance profile.

LTM-620 (Bivar Inc.): Longest available option at 0.620" (15.75mm). Manufactured from crystalline polymer rather than Nylon 66, with equivalent flame rating performance. ROHS3 compliant and active status. Highest inventory availability.

All substitutes maintain active product status and full regulatory compliance. Selection should be based on specific mechanical height requirements within the 14.50mm to 15.75mm range and material preference between Nylon 66 and crystalline polymer compositions.

Frequently Asked Questions (FAQ)

Q: Can 705820145 be used in place of 705820150? A: Yes. Both parts share identical LED form factor, material composition, color, and flame rating. The 705820145 is 0.020" (0.50mm) shorter, making it suitable for applications with tighter vertical clearance constraints.

Q: What is the maximum length variation among substitutes? A: The substitute parts range from 0.571" to 0.620" (14.50mm to 15.75mm), representing a total variation of 0.049" (1.25mm). Design layouts must accommodate this dimensional range.

Q: Is LTM-620 compatible with the same PCB footprint? A: LTM-620 supports the same T1/T1 3/4 LED form factor and is mechanically compatible. The crystalline polymer material provides equivalent UL94 V-2 flame rating performance. Verify mechanical clearance due to the 0.620" (15.75mm) length specification.

Q: Are all substitutes ROHS3 compliant? A: Yes. All four parts carry ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronics manufacturing.

Q: What is the primary difference between Würth Elektronik and Bivar Inc. options? A: Würth Elektronik parts (705820145, 705820155) are manufactured from Nylon 66. Bivar Inc. LTM-620 uses crystalline polymer. Both material types meet UL94 V-2 flame rating requirements and are ROHS3 compliant.

Q: Can these parts be interchanged without design modification? A: Interchangeability depends on mechanical height tolerance in the specific application. The 1.25mm total length variation across all substitutes must be evaluated against PCB layout and component clearance requirements.
