ELM 1-455 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-455 is a T1 3/4 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.455" (11.56mm) length. This component is classified as an active product and is ROHS3 compliant. LED standoffs serve as mechanical mounting and alignment components for T1 3/4 LED packages in vertical orientations. Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design specifications allow for minor dimensional variations within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 1-455 is determined by the following parameters:

Primary Substitution Criteria:

• LED Type: T1 3/4 (must match exactly)
• Material: Black PVC (must match exactly)
• Orientation: Vertical (SR VERT configuration)
• Manufacturer: Bivar Inc. (same manufacturer family)
• RoHS Compliance: ROHS3 Compliant (must maintain or exceed compliance level)
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Length tolerance: Substitute parts must have lengths within the ELM 3 series specification range (0.440" to 0.450"), representing a dimensional variation of ±0.015" from the primary part's 0.455" specification.

Both substitute parts (ELM 3-440 and ELM 3-450) belong to the ELM 3 series and maintain all critical electrical and mechanical parameters while offering minor length variations suitable for applications where precise standoff height can accommodate these tolerances.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-450 Selection: The ELM 3-450 represents the closest dimensional match to the ELM 1-455, with a length of 0.450" compared to 0.455", resulting in a 0.005" (0.127mm) reduction. This substitute maintains all active product status, ROHS3 compliance, and MSL 1 rating. The ELM 3-450 is suitable for applications where minimal height variation is acceptable and where the 0.005" difference does not impact circuit board layout or LED alignment requirements.

ELM 3-440 Selection: The ELM 3-440 offers a length of 0.440", representing a 0.015" (0.381mm) reduction from the primary part. This substitute is appropriate for designs with greater tolerance for standoff height variation or where space constraints benefit from the reduced length. The ELM 3-440 maintains full compliance with ROHS3 and MSL 1 specifications.

Both substitutes are manufactured by Bivar Inc. and carry active product status, ensuring continued availability and support. Selection between ELM 3-450 and ELM 3-440 depends on the specific mechanical clearance and alignment requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-440 and ELM 3-450 be used interchangeably with ELM 1-455?

A: Interchangeability depends on application-specific mechanical tolerances. Both substitutes maintain identical LED type (T1 3/4), material (Black PVC), orientation (Vertical), and compliance specifications. The length differences (0.015" for ELM 3-440 and 0.005" for ELM 3-450) must be evaluated against circuit board layout, LED alignment, and clearance requirements.

Q: What is the maximum length variation acceptable between these parts?

A: The ELM 3 series substitutes range from 0.440" to 0.450", representing a total variation band of 0.010". The ELM 1-455 at 0.455" falls outside this range by 0.005" to 0.015" depending on which substitute is selected.

Q: Are all three parts ROHS3 compliant?

A: Yes. The ELM 1-455, ELM 3-440, and ELM 3-450 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the difference between ELM 1 and ELM 3 series designations?

A: The series designation reflects the product line within Bivar Inc.'s LED standoff portfolio. Both series share identical functional specifications for T1 3/4 vertical LED standoffs in black PVC, with the primary distinction being length variants within each series.

Q: Are there inventory considerations when selecting substitutes?

A: Yes. Current inventory levels are: ELM 1-455 (939 Pcs), ELM 3-440 (22,638 Pcs), and ELM 3-450 (8,972 Pcs). The ELM 3 series substitutes offer significantly higher stock availability.

Q: Do these parts require different packaging or handling procedures?

A: All three parts are supplied in bag packaging with identical MSL 1 ratings, requiring no special moisture control during storage or handling.
