NTM-270 LED Standoff Equivalent & Substitute Parts

Part Overview

The NTM-270 is an active T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.270" (6.86mm) length specification. This component is constructed from black nylon material and serves as a mechanical support and alignment fixture for LED assemblies in electronic equipment.

Equivalent and substitute parts are identified when product availability changes, supply chain disruptions occur, or design revisions require component alternatives that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NTM-270 are qualified based on the following criteria:

Critical Parameters for Substitution:

• LED type compatibility (T1, T1 3/4)
• Material composition (Nylon)
• Color specification (Black)
• Mounting orientation (Vertical)
• RoHS3 compliance status
• Regulatory classification (ECCN, HTSUS codes)

Allowable Variance:

• Length tolerance: The substitute part 705820070 measures 0.276" (7.00mm), representing a 0.006" (0.14mm) dimensional variance from the main part specification. This variance remains within acceptable mechanical tolerances for LED standoff applications where precise height matching is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

Both the NTM-270 and 705820070 maintain active product status with full RoHS3 compliance and identical regulatory classifications. Selection between these parts should be based on:

Availability and Lead Time: The 705820070 (Würth Elektronik) currently maintains higher inventory levels (5553 pcs) compared to the NTM-270 (959 pcs), making it suitable for applications where supply continuity is a priority.

Material Specification: The 705820070 specifies Nylon 66 with UL94 V-2 rating, providing documented flame-retardant properties. The NTM-270 specifies general nylon material without additional flame-retardant certification details in the provided parameters.

Dimensional Tolerance: The 0.006" length difference between parts is acceptable for standard LED standoff applications. Design verification is required only if the assembly has height-critical constraints or if the standoff length directly affects circuit board clearance or component spacing.

Frequently Asked Questions (FAQ)

Q: Can the 705820070 directly replace the NTM-270 in existing designs?

A: Yes, provided the 0.006" (0.14mm) length difference does not violate design constraints. Both parts share identical LED type compatibility, material class, color, mounting orientation, and regulatory compliance status.

Q: What is the significance of the Nylon 66 specification in the 705820070?

A: Nylon 66 is a specific polyamide formulation with documented UL94 V-2 flame-retardant properties. This provides additional material certification compared to general nylon specifications. Selection depends on whether your application requires documented flame-retardant material properties.

Q: Are there any moisture sensitivity differences between these parts?

A: The NTM-270 specifies MSL 1 (Unlimited). The 705820070 lists MSL as Not Applicable, indicating it does not require moisture-sensitive device handling protocols. Both parts are suitable for standard storage and handling conditions.

Q: Do both parts share the same regulatory classifications?

A: Yes. Both parts carry identical ECCN (EAR99) and HTSUS (3926.90.9985) classifications, ensuring equivalent compliance status for export and import documentation.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bag packaging format, suitable for bulk component storage and automated assembly processes.
