LTM-270 Equivalent & Substitute Parts

Part Overview

The LTM-270 is a T1/T1 3/4 LED standoff manufactured by Bivar Inc., constructed from black crystalline polymer with a 0.270" (6.86mm) length. This component is designed for vertical mounting applications requiring precision LED alignment and mechanical support. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent functional performance can be achieved through alternative materials and manufacturers while maintaining critical dimensional and electrical specifications within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTM-270 are identified based on the following critical parameters:

Dimensional Compatibility: LED standoff length must accommodate T1/T1 3/4 form factors with length tolerance within 0.270" ± 0.006" (6.86mm ± 0.15mm) to maintain proper LED seating and vertical alignment in standard PCB mounting applications.

Material Equivalence: While the primary part uses crystalline polymer, substitute materials including nylon with UL94 V-2 flame rating provide equivalent mechanical support, dimensional stability, and electrical isolation properties required for LED standoff applications.

Color Specification: Black coloring is maintained across all substitutes to ensure consistent light-blocking properties and aesthetic uniformity in assembled devices.

Regulatory Compliance: All substitute parts maintain RoHS3 compliance and EAR99 export classification, ensuring regulatory equivalence for global supply chain applications.

LED Type Compatibility: Both main and substitute parts support T1 and T1 3/4 LED packages, confirming mechanical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (LTM-270): Select the LTM-270 when crystalline polymer material properties are specified in design documentation or when existing inventory supports production schedules. This part maintains Active status with 941 units in stock.

Substitute Selection (705820070): The Würth Elektronik 705820070 serves as a direct functional substitute when supply constraints affect LTM-270 availability. This part is RoHS3 compliant, maintains EAR99 export classification, and demonstrates superior inventory availability with 5,553 units in stock. The nylon material (UL94 V-2 rated) provides equivalent mechanical performance and electrical isolation for LED standoff applications. The 0.006" (0.14mm) length differential falls within standard manufacturing tolerances for T1/T1 3/4 LED mounting applications.

Both parts maintain Active product status and full regulatory compliance, supporting interchangeable use in production environments where material substitution does not violate design specifications.

Frequently Asked Questions (FAQ)

Q: Can the 705820070 directly replace the LTM-270 in existing designs?

A: Yes. Both parts support T1/T1 3/4 LED packages, maintain black coloring, and provide equivalent mechanical support. The 0.006" length difference is within standard PCB mounting tolerances for vertical LED standoff applications. Verify that design documentation does not explicitly require crystalline polymer material properties.

Q: What is the significance of the length tolerance between these parts?

A: The LTM-270 measures 0.270" (6.86mm) while the 705820070 measures 0.276" (7.00mm). This 0.006" (0.14mm) difference is acceptable for T1/T1 3/4 LED standoff applications where standard PCB mounting holes accommodate this variance. Both lengths support proper LED seating and vertical alignment.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LTM-270 and 705820070 are RoHS3 compliant, meeting regulatory requirements for restricted substance elimination in electronic components.

Q: What material difference exists between these parts?

A: The LTM-270 uses crystalline polymer while the 705820070 uses nylon with UL94 V-2 flame rating. Both materials provide equivalent electrical isolation, mechanical support, and dimensional stability for LED standoff applications. Nylon offers enhanced flame resistance properties.

Q: How do inventory levels affect part selection?

A: The LTM-270 has 941 units in stock while the 705820070 has 5,553 units available. When supply continuity is critical, the 705820070 provides greater inventory security for extended production runs.

Q: Are export classifications equivalent?

A: Yes. Both parts carry EAR99 classification and share identical HTSUS code 3926.90.9985, confirming equivalent export regulatory treatment.

Q: What is the moisture sensitivity level for each part?

A: The LTM-270 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 705820070 lists moisture sensitivity as Not Applicable, confirming equivalent handling requirements for storage and assembly processes.
