NTM-450 LED Standoff Equivalent & Substitute Parts

Part Overview

The NTM-450 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black nylon material with a length of 0.450" (11.43mm). This component is designed to provide mechanical support and vertical positioning for LED assemblies in electronic applications. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent functional performance is required due to inventory constraints, supply chain considerations, or design flexibility within specified mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NTM-450 are qualified based on the following critical parameters:

Mandatory Matching Parameters:

• LED Type: T1, T1 3/4 (mechanical compatibility with LED form factor)
• Material: Nylon (chemical and thermal properties)
• Color: Black (visual and application consistency)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• ECCN Classification: EAR99 (export control alignment)

Allowable Variation Parameter:

• Length: ±0.022" tolerance range (0.433" to 0.472") accommodates mechanical design flexibility within standard PCB assembly specifications

All substitute parts are sourced from Würth Elektronik and maintain Active product status with full inventory availability. The length variation across the substitute group reflects standard manufacturing tolerances for nylon LED standoffs within the T1/T1 3/4 category.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain equivalent functional classification as the NTM-450 based on matching LED type, material composition, color specification, and RoHS3 compliance status. Each substitute part is Active in product status, ensuring long-term availability and supply chain stability.

Selection Criteria by Length Requirement:

• 705820110 (0.433"): Shortest available substitute; suitable for applications requiring minimum standoff height
• 705820115 (0.453"): Closest length match to NTM-450 (0.450"); recommended for direct replacement scenarios
• 705820120 (0.472"): Longest available substitute; suitable for applications requiring maximum standoff height

All parts share identical ECCN classification (EAR99) and HTSUS coding (3926.90.9985), confirming regulatory and trade alignment. Würth Elektronik substitutes carry REACH Unaffected status, providing additional compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can 705820110, 705820115, and 705820120 be used interchangeably with NTM-450?

A: These parts are functionally equivalent within the specified length tolerance range (0.433" to 0.472"). Selection depends on the mechanical clearance requirements of the specific PCB assembly design. The 0.020" length variation between shortest and longest substitute must be evaluated against circuit board layout constraints.

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

A: Length variation reflects standard manufacturing tolerances for nylon LED standoffs. The 0.022" total range (±0.011" from nominal) is typical for injection-molded nylon components. Design specifications must accommodate this tolerance band to ensure proper LED positioning and electrical contact.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The NTM-450 and all three Würth Elektronik substitutes (705820110, 705820115, 705820120) are RoHS3 compliant, meeting EU Directive 2011/65/EU requirements for restricted hazardous substances.

Q: What is the difference between Bivar Inc. and Würth Elektronik sourcing?

A: Both manufacturers produce equivalent T1/T1 3/4 LED standoffs in black nylon with identical electrical and mechanical properties. Würth Elektronik substitutes provide alternative sourcing with higher inventory levels (2240–5318 units) compared to NTM-450 (1097 units).

Q: Does packaging differ between the main part and substitutes?

A: All parts are supplied in Bag packaging format, maintaining consistent handling and storage requirements across the product group.

Q: Are there any compliance or certification differences?

A: All parts share EAR99 ECCN classification and 3926.90.9985 HTSUS coding. Würth Elektronik parts carry REACH Unaffected status. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for NTM-450 and Not Applicable for Würth Elektronik substitutes, indicating equivalent or superior moisture tolerance.
