LTM-650 LED Standoff Equivalent & Substitute Parts

Part Overview

The LTM-650 is an LED mounting standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED components. This black crystalline polymer standoff features a 0.650" (16.51mm) vertical height and two-lead configuration. The product is currently active and widely used in LED assembly applications. Finding equivalent and substitute parts is essential for inventory optimization, design flexibility, and ensuring supply chain continuity across manufacturing cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LTM-650 is determined by the following critical parameters: LED type compatibility (T1, T1 3/4), lead configuration (2-lead), color (black), and RoHS3 compliance. Length variation within manufacturing tolerance ranges and material differences between crystalline polymer and nylon are acceptable substitution parameters provided all other electrical and mechanical specifications remain compatible.

The LTM-650 has two identified substitute parts:

• LTM-620 (Bivar Inc.): Same manufacturer, same LED type, same material, and same color. Length differs by 0.030" (0.76mm).
• 705820170 (Würth Elektronik): Different manufacturer and material (nylon instead of crystalline polymer). Length differs by 0.019" (0.48mm). LED type and color specifications match.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LTM-650, LTM-620, and 705820170—are active products with ROHS3 compliance certification, ensuring regulatory compliance for current manufacturing standards. Selection between these parts depends on specific length requirements for your application and material constraints.

The LTM-620 represents the closest match to the LTM-650, sharing identical manufacturer, material composition, and MSL rating. The 705820170 offers an alternative with different material (nylon) and slightly different length, suitable for applications where nylon material properties are acceptable and the marginal length variation does not affect assembly or performance.

Frequently Asked Questions (FAQ)

Q: Can I interchange LTM-620 with LTM-650? A: Both parts share the same LED type (T1, T1 3/4), material (crystalline polymer), color (black), two-lead configuration, and RoHS3 compliance. The primary difference is length: LTM-620 is 0.030" shorter. Interchangeability depends on whether your application tolerates this length difference.

Q: What makes 705820170 a valid substitute? A: The 705820170 maintains compatibility across LED type (T1, T1 3/4), color (black), two-lead configuration, and RoHS3 compliance. The material differs (nylon versus crystalline polymer), and the length is 0.019" longer. Both material and length differences are within acceptable substitution parameters.

Q: How do material differences affect substitution? A: Crystalline polymer and nylon are both thermoplastic materials suitable for LED standoff applications. Material selection should consider your specific environmental exposure, thermal requirements, and mechanical stress conditions. Both materials are ROHS3 compliant.

Q: Are all three parts currently available? A: Yes. LTM-650 has 895 units in stock, LTM-620 has 5,359 units in stock, and 705820170 has 2,714 units in stock, all listed as new original inventory.

Q: What does MSL 1 (Unlimited) mean? A: Moisture Sensitivity Level 1 indicates the lowest sensitivity to moisture. Parts with MSL 1 have unlimited floor life and require no special moisture-control handling during storage or assembly.
