ELM 3-340 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 3-340 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.340" (8.64mm) length. This component is designed for vertical mounting applications requiring precise height specifications. The part maintains Active product status and is RoHS3 compliant, making it suitable for current production environments. Substitute parts become necessary when the primary part experiences inventory constraints, supply chain disruptions, or when design specifications allow for minor dimensional variations within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 3-340 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 3/4 (must match exactly)
• Material: Black PVC (must match exactly)
• Mounting Style: Vertical (must match exactly)
• Color: Black (must match exactly)
• RoHS Status: ROHS3 Compliant (must match or exceed)
• MSL Rating: 1 (Unlimited) (must match or exceed)

Secondary Consideration:

• Length tolerance: Substitute parts with lengths within ±0.015" (±0.38mm) of the primary part are classified as parametric equivalents

The ELM 1-350 and ELM 3-335 both satisfy all primary criteria. The ELM 1-350 has a length of 0.350" (8.89mm), representing a +0.010" variance. The ELM 3-335 has a length of 0.335" (8.51mm), representing a −0.005" variance. Both fall within acceptable dimensional tolerance ranges for vertical LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 3-340, ELM 1-350, and ELM 3-335—maintain Active product status and full RoHS3 compliance, confirming their suitability for current production use. The selection between these parts depends on dimensional requirements specific to the application circuit board layout and LED mounting height specifications.

The ELM 3-335 offers the closest dimensional match to the primary part, with only a −0.005" length variance. This substitute is optimal when minimal height deviation is required.

The ELM 1-350 introduces a +0.010" length increase and belongs to a different series (ELM 1 versus ELM 3). This part is suitable for applications where slightly increased standoff height is acceptable or beneficial.

All parts share identical LED type, material composition, color, and compliance certifications, ensuring functional interchangeability within the specified dimensional tolerance window.

Frequently Asked Questions (FAQ)

Q: What determines whether ELM 1-350 and ELM 3-335 can substitute for ELM 3-340?

A: Substitution is based on matching LED type (T1 3/4), material (Black PVC), color (Black), mounting style (Vertical), and compliance ratings (ROHS3, MSL 1). Length variations within ±0.015" are acceptable for parametric equivalency in vertical standoff applications.

Q: What is the length difference between the main part and each substitute?

A: ELM 3-340 is 0.340" (8.64mm). ELM 1-350 is 0.010" longer at 0.350" (8.89mm). ELM 3-335 is 0.005" shorter at 0.335" (8.51mm).

Q: Are there series differences between ELM 3-340 and ELM 1-350?

A: Yes. ELM 3-340 belongs to the ELM 3 series, while ELM 1-350 belongs to the ELM 1 series. Despite this series designation difference, both parts meet all parametric equivalency criteria for substitution.

Q: Do all three parts have identical RoHS and MSL ratings?

A: Yes. All three parts are ROHS3 compliant with MSL rating 1 (Unlimited), confirming equivalent environmental and moisture sensitivity performance.

Q: Which substitute offers the closest dimensional match?

A: ELM 3-335 provides the closest match with only a −0.005" length variance from the primary ELM 3-340 part.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on the specific application's height tolerance requirements. Applications with strict height specifications may require evaluation of the dimensional variance before substitution.
