NTM-330 LED Standoff Equivalent & Substitute Parts

Part Overview

The NTM-330 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.330" (8.38mm) length. This component is constructed from black nylon material and is classified as Active product status with full RoHS3 compliance. LED standoffs serve as mechanical spacers and alignment fixtures in electronic assemblies, positioning light-emitting diodes at precise heights above printed circuit boards. Equivalent substitute parts are identified based on matching electrical and mechanical parameters within acceptable tolerance ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NTM-330 are qualified based on the following criteria:

Primary Matching Parameters:

• LED Type: T1, T1 3/4 (identical)
• Material: Nylon (identical)
• Color: Black (identical)
• RoHS3 Compliance: Required
• Product Status: Active

Tolerance Parameter:

• Length: 0.330" ± 0.020" (8.38mm ± 0.51mm) — mechanical standoff height tolerance for vertical mounting applications

The substitute parts identified (705820080 and 705820085, both from Würth Elektronik) maintain identical LED type, material, and color specifications. Length variations of 0.315" (8.00mm) and 0.335" (8.50mm) fall within acceptable mechanical tolerance ranges for LED standoff applications where precise vertical spacing is required but minor height variations do not compromise circuit board assembly or optical performance.

Parameter Comparison

Engineering Selection Recommendations

NTM-330 (Bivar Inc.): Select this part when the original design specification requires exactly 0.330" (8.38mm) standoff height and Bivar Inc. sourcing is mandated by procurement or supply chain requirements. Product is Active with full RoHS3 compliance and unlimited moisture tolerance (MSL 1).

705820080 (Würth Elektronik): This substitute provides the shortest standoff height at 0.315" (8.00mm), representing a 0.015" (0.38mm) reduction from the NTM-330 specification. Select this part when design tolerance permits reduced vertical spacing or when Würth Elektronik supply chain offers cost or availability advantages. RoHS3 compliant with high inventory availability (17403 Pcs).

705820085 (Würth Elektronik): This substitute provides the closest standoff height match at 0.335" (8.50mm), representing a 0.005" (0.12mm) increase from the NTM-330 specification. Select this part when design tolerance permits minimal height increase or when Würth Elektronik supply chain offers cost or availability advantages. RoHS3 compliant with active product status.

All three parts share identical LED type (T1/T1 3/4), material composition (nylon), color (black), and regulatory compliance (RoHS3). Selection between parts should be based on specific mechanical height requirements within the assembly design and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 705820080 and 705820085 be used interchangeably with NTM-330 in the same circuit board assembly?

A: Interchangeability depends on the mechanical tolerance of the printed circuit board design. Both Würth Elektronik parts maintain identical LED type, material, and color specifications. The 705820080 is 0.015" shorter and the 705820085 is 0.005" taller than the NTM-330. If the assembly design accommodates ±0.020" height variation, both parts are mechanically compatible. If the design requires exact 0.330" height, only the NTM-330 or 705820085 (within 0.005") should be used.

Q: What is the difference between NTM-330 and the Würth Elektronik substitutes in terms of material specification?

A: The NTM-330 is specified as nylon material. The Würth Elektronik parts (705820080 and 705820085) are specified as Nylon 66, which is a specific engineering-grade nylon polymer. Both materials are nylon-based dielectric polymers suitable for LED standoff applications. Nylon 66 is a standardized material grade with defined mechanical and thermal properties.

Q: Are all three parts RoHS3 compliant?

A: Yes. The NTM-330, 705820080, and 705820085 are all RoHS3 compliant, meeting hazardous substance restriction requirements for electronic component manufacturing.

Q: What is the significance of the MSL (Moisture Sensitivity Level) difference between NTM-330 and the Würth Elektronik parts?

A: The NTM-330 is rated MSL 1 (Unlimited), indicating no moisture precautions are required during storage, handling, or assembly. The Würth Elektronik parts list MSL as Not Applicable, which is typical for passive polymer components that do not absorb moisture in ways that affect electrical performance. Both designations indicate these parts do not require special moisture control measures.

Q: Which substitute part should be selected for maximum inventory availability?

A: The 705820080 offers the highest inventory availability at 17403 Pcs, compared to 1971 Pcs for 705820085 and 698 Pcs for the NTM-330. If supply chain continuity is a primary concern, 705820080 provides the largest available stock, provided the 0.015" height reduction is acceptable for the application.

Q: Can these LED standoffs be used in applications requiring UL94 V-2 flame rating?

A: The Würth Elektronik parts (705820080 and 705820085) are explicitly specified as UL94 V-2 compliant. The NTM-330 does not list UL94 rating in the provided specifications. If UL94 V-2 flame rating is a design requirement, the Würth Elektronik substitutes are the appropriate selection.
