NTM-620 Equivalent & Substitute Parts

Part Overview

The NTM-620 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black nylon material with a 0.620" (15.75mm) length. This component maintains Active product status and is RoHS3 compliant. Equivalent and substitute parts become necessary when inventory constraints occur, when alternative material compositions better suit specific applications, or when sourcing from multiple manufacturers provides supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NTM-620 is based on the following critical parameters:

• LED Size Classification: All substitute parts must support T1 and T1 3/4 LED form factors
• Length Tolerance: Parts within 0.591" to 0.620" (15.00mm to 15.75mm) are functionally compatible
• Material Composition: Nylon and crystalline polymer materials are acceptable alternatives
• Color: Black finish is maintained across all substitutes
• RoHS Compliance: All parts must meet ROHS3 standards
• Moisture Sensitivity: MSL 1 (Unlimited) rating is required

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LTM-620 (Bivar Inc.) provides direct substitution with identical length specification and superior inventory availability (5359 pieces). The crystalline polymer material maintains mechanical and electrical properties equivalent to the nylon construction while delivering enhanced availability.

Secondary Substitutes: The Würth Elektronik 705820150 and 705820155 offer compatible substitution within length tolerances of ±0.029" and ±0.010" respectively from the nominal 0.620" specification. Both maintain T1/T1 3/4 LED compatibility and ROHS3 compliance. Selection between these alternatives should prioritize the 705820155 variant due to its superior length alignment (0.610" versus 0.591").

All listed substitutes maintain Active product status and required regulatory certifications, qualifying them for direct component replacement in applications where the specified dimensional and material parameters are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the LTM-620 directly replace the NTM-620? A: Yes. The LTM-620 shares identical length (0.620"), LED size classification (T1/T1 3/4), color (black), and RoHS3 compliance. The material differs (crystalline polymer versus nylon) but maintains functional equivalence for the LED standoff application.

Q: What is the maximum length deviation allowable when substituting the Würth Elektronik parts? A: The 705820155 exhibits a 0.010" length deviation (0.610" versus 0.620"), while the 705820150 exhibits a 0.029" deviation (0.591" versus 0.620"). Selection depends on application-specific dimensional tolerances.

Q: Are all substitute parts RoHS3 compliant? A: Yes. NTM-620, LTM-620, 705820150, and 705820155 all maintain ROHS3 compliance, meeting regulatory requirements for restricted substance elimination.

Q: Do the Würth Elektronik parts have moisture sensitivity level specifications? A: The 705820150 and 705820155 list MSL as Not Applicable. The NTM-620 and LTM-620 both specify MSL 1 (Unlimited), indicating superior moisture resistance characteristics.

Q: Which substitute offers the best inventory availability? A: The LTM-620 provides the highest inventory level at 5359 pieces, compared to 906 pieces for the original NTM-620, 2358 pieces for the 705820155, and 1325 pieces for the 705820150.
