LTM-430 Equivalent & Substitute Parts

Part Overview

The LTM-430 is an LED standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This component features a black crystalline polymer construction with a 0.430" (10.92mm) length and vertical mounting orientation. The part is currently in active production status with full RoHS3 compliance and MSL Level 1 rating, indicating unlimited moisture resistance. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining functional and mechanical compatibility.

Key Parameters

Parameter	Value	Criticality for Substitution
LED Type	T1, T1 3/4	Critical
Color	Black	Critical
Length	0.430" (10.92mm)	Critical
Material	Crystalline Polymer	Important
Orientation	Vertical	Critical
RoHS Status	ROHS3 Compliant	Critical
Moisture Sensitivity Level	MSL 1 (Unlimited)	Important

Substitute Part Grouping Explanation

Substitute parts for the LTM-430 are qualified based on the following parameters:

Critical Matching Parameters:

LED Type: T1, T1 3/4 compatibility required
Color: Black finish required
Length: Within acceptable tolerance range (0.413" to 0.433")
Orientation: Vertical mounting configuration
RoHS3 Compliance: Required for regulatory alignment

Important Matching Parameters:

Material composition: Polymer-based construction (crystalline polymer or nylon acceptable)
Moisture sensitivity: MSL 1 or equivalent non-applicable rating

The identified substitutes (705820105 and 705820110) satisfy all critical parameters while offering alternative material compositions and length specifications within the functional tolerance band. Both substitutes maintain identical LED type compatibility, color specification, and regulatory compliance status.

Engineering Selection Recommendations

LTM-430 (Bivar Inc.): Select this part when crystalline polymer material properties are specified in the design. The part maintains active production status with full RoHS3 compliance and MSL Level 1 rating. Current inventory of 792 pieces supports immediate availability.

705820105 (Würth Elektronik): This substitute provides a 0.413" (10.50mm) length specification, representing a 0.017" (0.42mm) reduction from the main part. The nylon 66 material construction with UL94 V-2 rating maintains RoHS3 compliance and REACH unaffected status. Inventory of 2331 pieces supports high-volume requirements. Select when the shorter length specification accommodates the application envelope.

705820110 (Würth Elektronik): This substitute provides a 0.433" (11.00mm) length specification, representing a 0.003" (0.08mm) increase from the main part. The nylon 66 material construction with UL94 V-2 rating maintains RoHS3 compliance and REACH unaffected status. Inventory of 5318 pieces provides maximum availability. Select when the slightly longer length specification is compatible with the application requirements.

All three parts maintain identical LED type compatibility, black color specification, vertical orientation, and regulatory compliance status. Selection between substitutes depends on specific length tolerance requirements within the application design.

Frequently Asked Questions (FAQ)

Q: Can 705820105 or 705820110 be used interchangeably with LTM-430?

A: Both Würth Elektronik parts are parametric equivalents for T1 and T1 3/4 LED standoff applications. Interchangeability depends on the specific length tolerance requirements of the application. The 705820105 is 0.017" shorter, while 705820110 is 0.003" longer than the LTM-430. Verify that the application design accommodates these length variations.

Q: What is the material difference between LTM-430 and the Würth substitutes?

A: The LTM-430 uses crystalline polymer construction, while both Würth Elektronik substitutes (705820105 and 705820110) use nylon 66 material. Both material types are polymer-based and maintain equivalent RoHS3 compliance and regulatory status. Material selection should be based on specific thermal, mechanical, or chemical resistance requirements of the application.

Q: Are all three parts RoHS3 compliant?

A: Yes. The LTM-430, 705820105, and 705820110 all carry ROHS3 Compliant status. Additionally, the Würth Elektronik parts carry REACH Unaffected designation, confirming full regulatory alignment.

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

A: The LTM-430 carries MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions. The Würth Elektronik substitutes (705820105 and 705820110) list MSL as Not Applicable, confirming equivalent or superior moisture resistance characteristics.

Q: Which substitute offers the best inventory availability?

A: The 705820110 provides the highest inventory level at 5318 pieces, followed by 705820105 at 2331 pieces. The LTM-430 has 792 pieces in stock. Selection should prioritize application length requirements over inventory considerations.

Q: Are the packaging specifications identical across all three parts?

A: Yes. All three parts are supplied in Bag packaging format, maintaining consistent handling and storage requirements.
