ELM 4-520 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-520 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.520" (13.21mm) vertical mounting height. This component is classified as an active product and is ROHS3 compliant. LED standoffs serve as mechanical and electrical mounting solutions for T1 LED assemblies in circuit board applications. Substitute parts become necessary when the primary part is unavailable, when inventory constraints exist, or when design specifications allow for minor dimensional variations within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-520 are determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Color: Black (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)

Variable Parameter Allowing Substitution:

• Length: The ELM 4-520 operates at 0.520" (13.21mm). Substitute parts with lengths of 0.500" (12.70mm) and 0.510" (12.95mm) are acceptable alternatives when dimensional tolerance permits a maximum variance of ±0.020" from the primary specification.

Both substitute parts (ELM 2-500 and ELM 2-510) maintain identical material composition, LED compatibility, compliance certifications, and moisture sensitivity ratings as the primary part. The series designation change from ELM 4 to ELM 2 reflects internal product line organization and does not affect functional equivalency.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-510 Selection Criteria: The ELM 2-510 represents the closest dimensional match to the ELM 4-520, with a length variance of only 0.010" (0.26mm). This substitute is suitable for applications where the primary part is unavailable and design specifications accommodate a maximum height reduction of 0.010". The part maintains full ROHS3 compliance and identical material properties. Current inventory availability is 1846 pieces.

ELM 2-500 Selection Criteria: The ELM 2-500 provides an alternative with a length variance of 0.020" (0.51mm) from the primary specification. This substitute is applicable in designs where vertical clearance permits a 0.020" reduction in standoff height. The part maintains full ROHS3 compliance and identical material properties. Current inventory availability is 4519 pieces.

Compliance Verification: All substitute parts carry identical RoHS3 compliance certification and Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage protocols. All parts are manufactured by Bivar Inc. and packaged in bags.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 4-520 and its substitutes? A: The primary difference is the standoff length. The ELM 4-520 measures 0.520" (13.21mm), while ELM 2-510 measures 0.510" (12.95mm) and ELM 2-500 measures 0.500" (12.70mm). All other parameters—LED type, material, color, compliance, and moisture sensitivity—are identical.

Q: Can ELM 2-500 and ELM 2-510 be used interchangeably with ELM 4-520? A: Interchangeability depends on design specifications. If the circuit board layout and component clearances accommodate the reduced heights (0.010" or 0.020" shorter), these parts are functionally equivalent. If exact height is critical to the design, substitution is not appropriate.

Q: Are all three parts ROHS3 compliant? A: Yes. The ELM 4-520, ELM 2-510, and ELM 2-500 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the inventory status of each part? A: ELM 4-520 has 1091 pieces in stock, ELM 2-510 has 1846 pieces in stock, and ELM 2-500 has 4519 pieces in stock.

Q: Do the substitute parts use the same packaging? A: Yes. All three parts are packaged in bags.

Q: What LED type do all these standoffs accommodate? A: All three standoffs are designed for T1 LED components.
