LTM-340 LED Standoff Mount: Equivalent & Substitute Parts

Part Overview

The LTM-340 is an LED standoff mount designed for T1 and T1 3/4 LED packages. Manufactured by Bivar Inc., this component features a 0.340" (8.64mm) length and is constructed from black PVC material. The part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to inventory availability, specific mechanical clearance requirements, or material property preferences in application-specific designs.

Key Parameters

Substitute Part Grouping Explanation

The LTM-350 qualifies as a parametric equivalent to the LTM-340 based on the following matching criteria:

Matching Parameters:

• Manufacturer: Bivar Inc. (same source)
• Series: LTM (same product family)
• LED Compatibility: T1, T1 3/4 (identical LED package support)
• Color: Black (identical aesthetic specification)
• RoHS Status: ROHS3 Compliant (equivalent regulatory compliance)
• MSL Rating: 1 (Unlimited) (identical moisture sensitivity)
• Product Status: Active (both currently manufactured)

Distinguishing Parameter:

• Length: 0.350" (8.89mm) versus 0.340" (8.64mm) — represents a 0.010" (0.25mm) mechanical difference
• Material: Crystalline Polymer versus PVC — different base material composition

Substitution is valid when the 0.010" length increase and material change do not conflict with mechanical assembly constraints or application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both LTM-340 and LTM-350 maintain Active product status and full ROHS3 compliance, qualifying both for current production applications. Selection between these parts depends on mechanical clearance tolerance:

The LTM-340 (0.340" length, PVC) is the primary specification when exact dimensional constraints require the shorter standoff height.

The LTM-350 (0.350" length, Crystalline Polymer) serves as a substitute when the additional 0.010" (0.25mm) length is mechanically acceptable and when Crystalline Polymer material properties align with application requirements.

Both parts carry identical MSL 1 ratings and export classifications (EAR99), eliminating compliance concerns during substitution.

Frequently Asked Questions (FAQ)

Q: Can LTM-350 directly replace LTM-340 in all applications?

A: Substitution is valid only when the 0.010" (0.25mm) length increase does not violate mechanical assembly constraints. Verify available clearance above the LED package before substitution.

Q: What is the material difference between these parts?

A: LTM-340 uses PVC; LTM-350 uses Crystalline Polymer. Both materials are black and support identical LED packages. Material selection may affect thermal or chemical resistance properties specific to the application environment.

Q: Are both parts RoHS compliant?

A: Yes. Both LTM-340 and LTM-350 are ROHS3 Compliant with identical MSL 1 (Unlimited) ratings, suitable for standard PCB assembly processes.

Q: What LED packages do these standoffs support?

A: Both parts accommodate T1 and T1 3/4 LED packages exclusively.

Q: Are there inventory or lead time considerations?

A: LTM-340 inventory: 933 Pcs. LTM-350 inventory: 893 Pcs. Both are in stock as new original components.
