NTM-500 Equivalent & Substitute Parts

Part Overview

The NTM-500 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.500" (12.70mm) length. Constructed from black nylon material, this component is classified as Active product status and maintains full ROHS3 compliance. LED standoffs serve as mechanical spacers and alignment fixtures for LED component placement in electronic assemblies. Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design specifications permit dimensional or material variations within established tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTM-500 is determined by the following critical parameters: LED type compatibility (T1/T1 3/4), color (black), RoHS3 compliance status, and dimensional tolerance of the length specification. The substitute parts listed maintain identical LED type classification and color specification. Length variations across the substitute group range from 0.492" to 0.520", representing dimensional tolerances typical for mechanical standoff applications. Material composition varies between nylon and crystalline polymer formulations, both of which are acceptable alternatives within the standoff category. All substitute parts maintain ROHS3 compliance and identical packaging format (Bag). Moisture sensitivity classification and REACH compliance status are provided where applicable for regulatory reference.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, establishing baseline compatibility with the NTM-500. Selection between substitute options depends on specific dimensional requirements within the assembly design.

LTM-520 (Bivar Inc.) represents a direct manufacturer alternative with identical LED type and color specification. The 0.020" (0.51mm) length increase from the main part specification requires verification against assembly height constraints. Material composition differs (crystalline polymer versus nylon), which may affect mechanical properties in specific thermal or mechanical stress environments.

705820125 (Würth Elektronik) provides a nylon-based alternative with length specification of 0.492" (12.50mm), representing a 0.008" (0.20mm) reduction from the main part. This option maintains material consistency with the NTM-500 and accommodates applications requiring reduced standoff height.

705820130 (Würth Elektronik) offers a nylon-based alternative with length specification of 0.512" (13.00mm), representing a 0.012" (0.30mm) increase from the main part. This option maintains material consistency with the NTM-500 and accommodates applications requiring increased standoff height.

All substitute parts carry ROHS3 compliance certification and identical HTSUS classification (3926.90.9985), confirming regulatory and tariff equivalence.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the NTM-500?

A: Substitute parts must maintain identical LED type classification (T1/T1 3/4), color (black), ROHS3 compliance status, and packaging format (Bag). Length variations are acceptable within the dimensional tolerance range established for mechanical standoff applications. Material composition (nylon or crystalline polymer) is interchangeable within this product category.

Q: What is the acceptable length tolerance range for NTM-500 substitutes?

A: The substitute parts provided range from 0.492" (12.50mm) to 0.520" (13.21mm), representing a total tolerance band of 0.028" (0.71mm) around the main part specification of 0.500" (12.70mm). Selection within this range depends on specific assembly height requirements and mechanical clearance specifications.

Q: Are there material differences between substitute options?

A: Yes. The NTM-500 and 705820125/705820130 are constructed from nylon material. The LTM-520 is constructed from crystalline polymer. Both material types are acceptable for T1/T1 3/4 LED standoff applications and maintain equivalent electrical and mechanical performance characteristics within this product category.

Q: Do all substitute parts meet the same regulatory requirements as the NTM-500?

A: Yes. All substitute parts listed carry ROHS3 compliance certification. The Würth Elektronik parts (705820125 and 705820130) additionally carry REACH Unaffected status. All parts share identical HTSUS classification (3926.90.9985) and ECCN designation (EAR99).

Q: What is the inventory status of substitute parts?

A: LTM-520 maintains 60,748 pieces in stock. 705820125 maintains 3,195 pieces in stock. 705820130 maintains 3,297 pieces in stock. The NTM-500 maintains 814 pieces in stock. Inventory levels are subject to change and should be verified at time of procurement.

Q: Can LTM-520 be used as a direct replacement despite material composition differences?

A: LTM-520 can be used as a substitute when assembly design specifications permit the 0.020" (0.51mm) length increase and when crystalline polymer material properties are acceptable for the application environment. Material selection should be verified against thermal, mechanical, and chemical exposure requirements specific to the end application.
