NTM-280 Equivalent & Substitute Parts

Part Overview

The NTM-280 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.280" (7.11mm) length. Constructed from black nylon material, this component provides mechanical support and alignment for LED assemblies in standard through-hole configurations. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Identification of equivalent and substitute parts becomes necessary when managing supply chain continuity, addressing component availability constraints, or consolidating supplier relationships while maintaining functional and mechanical compatibility within specified tolerance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTM-280 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• LED form factor: T1 or T1 3/4 compatibility required
• Material composition: Nylon construction
• Color: Black
• Length tolerance: Mechanical height within acceptable assembly clearance range
• RoHS3 compliance status
• Packaging format: Bag configuration

The substitute part 705820070 (Würth Elektronik) qualifies as a parametric equivalent based on matching LED type (T1, T1 3/4), material (Nylon), color (Black), and RoHS3 compliance. The length specification of 0.276" (7.00mm) falls within the acceptable tolerance band for vertical LED standoff applications, representing a 0.004" (0.11mm) dimensional variance from the primary part.

Engineering Selection Recommendations

Primary Part Selection (NTM-280): The NTM-280 remains the specified component for new designs and applications where Bivar Inc. supply chain relationships are established. Active product status and confirmed inventory (1001 pcs) support continued procurement without supply risk.

Substitute Part Selection (705820070): The Würth Elektronik 705820070 serves as a direct parametric equivalent for applications requiring alternative sourcing. This substitute maintains identical functional specifications across LED compatibility, material composition, color, and regulatory compliance. The 0.004" length differential represents standard manufacturing tolerance and does not impact mechanical assembly or electrical performance in vertical standoff applications. Active product status and higher inventory availability (5553 pcs) provide supply chain flexibility.

Selection Criteria:

• Both parts satisfy ROHS3 compliance requirements
• Both parts carry identical ECCN and HTSUS classifications
• Dimensional variance falls within standard mechanical tolerances for LED standoff applications
• Supplier selection may be based on availability, lead time, or cost considerations without functional compromise

Frequently Asked Questions (FAQ)

Q: Can the 705820070 be used as a direct replacement for the NTM-280 in existing assemblies?

A: Yes. The 705820070 qualifies as a parametric equivalent based on matching LED type (T1, T1 3/4), material (Nylon), color (Black), and RoHS3 compliance. The 0.004" length difference falls within acceptable mechanical tolerance for vertical LED standoff mounting.

Q: What is the significance of the length difference between 0.280" and 0.276"?

A: The 0.004" (0.11mm) variance represents standard manufacturing tolerance in nylon standoff production. This difference does not affect LED alignment, PCB clearance, or electrical performance in typical through-hole mounting applications.

Q: Are both parts suitable for the same environmental and storage conditions?

A: The NTM-280 carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The 705820070 lists MSL as Not Applicable, indicating equivalent or superior moisture performance. Both parts are suitable for standard industrial storage and handling conditions.

Q: Do both parts carry the same regulatory certifications?

A: Yes. Both the NTM-280 and 705820070 are ROHS3 compliant and classified under identical ECCN (EAR99) and HTSUS (3926.90.9985) codes, ensuring equivalent regulatory status for procurement and export purposes.

Q: What packaging format is used for both parts?

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

Q: Can these parts be intermixed in production inventory?

A: Yes, provided assembly documentation and bill of materials are updated to reflect the substitute part number. The parametric equivalence ensures functional interchangeability without design modification.
