Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NTM-670 are identified based on strict parameter matching across the following criteria:

LED Type Compatibility: Both the main part and substitute must support T1 and T1 3/4 LED packages to ensure mechanical fit within the standoff socket.

Dimensional Tolerance: Length specifications must fall within acceptable manufacturing tolerances. The NTM-670 specifies 0.670" (17.02mm), and the substitute part 705820170 specifies 0.669" (17.00mm), representing a 0.02mm variance within standard mechanical tolerances for nylon molded components.

Material Specification: Both parts must be constructed from nylon to maintain consistent electrical insulation, thermal stability, and mechanical properties in the assembly.

Color Matching: Black color specification must be maintained for visual consistency and application requirements.

Regulatory Compliance: Both parts must maintain RoHS3 compliance status to satisfy environmental and regulatory standards.

Packaging Format: Both parts are supplied in Bag packaging, ensuring consistent handling and inventory management.

The substitute part 705820170 from Würth Elektronik satisfies all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The NTM-670 from Bivar Inc. is the specified component and should be used when available and project requirements do not necessitate substitution.

Substitute Selection Criteria: The 705820170 from Würth Elektronik is a valid parametric equivalent when the NTM-670 is unavailable or when supply chain considerations require alternative sourcing. Both parts maintain Active product status and RoHS3 compliance, ensuring regulatory alignment.

Dimensional Consideration: The 0.02mm length difference between the NTM-670 (17.02mm) and 705820170 (17.00mm) falls within standard manufacturing tolerances for injection-molded nylon components and does not impact functional performance in typical LED standoff applications.

Material Specification: The Würth Elektronik part specifies Nylon 66 with UL94 V-2 rating, providing equivalent electrical insulation and mechanical properties to the standard nylon specification of the NTM-670.

Compliance Assurance: Both parts satisfy ROHS3 compliance and share identical HTSUS classification, confirming regulatory and tariff equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 705820170 be used as a direct replacement for the NTM-670?

A: Yes. The 705820170 is a parametric equivalent that matches all critical specifications: T1/T1 3/4 LED compatibility, black nylon construction, length within acceptable tolerance (0.02mm variance), RoHS3 compliance, and identical packaging format.

Q: What is the significance of the 0.02mm length difference?

A: The difference between 17.02mm (NTM-670) and 17.00mm (705820170) is within standard manufacturing tolerances for injection-molded nylon components. This variance does not affect mechanical fit or functional performance in LED standoff applications.

Q: Does the Nylon 66 specification of the 705820170 differ functionally from the NTM-670?

A: Nylon 66 is a standard nylon material grade that provides equivalent electrical insulation, thermal stability, and mechanical properties. The UL94 V-2 rating on the 705820170 indicates flame-retardant performance consistent with standoff component requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the NTM-670 and 705820170 maintain RoHS3 compliance status, satisfying environmental and regulatory requirements for electronic component use.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Bag packaging, ensuring consistent handling, storage, and inventory management practices.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that design specifications do not impose additional constraints beyond the parameters listed. Both parts are Active status components with equivalent regulatory compliance and mechanical compatibility with T1 and T1 3/4 LED packages.
