ELM 2-490 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-490 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.490" (12.45mm) vertical height. This component is designed for mounting 3mm LEDs in vertical orientation with 2-lead configuration. The part maintains Active product status and is RoHS3 compliant, making it suitable for current production applications. Alternative models become necessary when specific height requirements vary due to PCB layout constraints, assembly tolerances, or design modifications that require standoff lengths outside the 0.490" specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-490 is determined by the following parameters: LED type (T1), material composition (black PVC), mounting orientation (vertical), lead configuration (2-lead), and compliance certifications (RoHS3). All substitute parts listed maintain identical specifications across these core criteria. The primary variable among substitutes is the standoff length, which ranges from 0.485" to 0.510". This dimensional variation accommodates different PCB-to-LED clearance requirements while preserving all other functional and compliance characteristics. All substitute parts are manufactured by Bivar Inc. and share the same series classification structure (ELM 2 or ELM 5 series).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts for the ELM 2-490 maintain Active product status and full RoHS3 compliance, ensuring compatibility with current manufacturing standards and regulatory requirements. Selection among ELM 2-490, ELM 2-500, ELM 2-510, and ELM 5-485 should be based solely on the required standoff length specification for your application. The ELM 5-485 offers the shortest height at 0.485" (12.32mm), while the ELM 2-510 provides the maximum height at 0.510" (12.95mm). All parts share identical LED type (T1), material (black PVC), and electrical characteristics, differing only in vertical dimension. Inventory availability is documented for all options, with ELM 5-485 maintaining the highest stock level at 10,054 pieces.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 2-490 and its substitutes?

A: The primary difference is standoff length. ELM 2-490 measures 0.490" (12.45mm), while substitutes range from 0.485" to 0.510". All other specifications—LED type, material, mounting orientation, and compliance—remain identical.

Q: Can ELM 2-500 replace ELM 2-490 in my design?

A: ELM 2-500 can replace ELM 2-490 if your PCB layout tolerates an additional 0.010" (0.25mm) in standoff height. Both parts are functionally equivalent across all parameters except length.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ELM 2-490, ELM 2-500, ELM 2-510, and ELM 5-485 are all RoHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the difference between ELM 2 series and ELM 5 series standoffs?

A: Based on provided specifications, both series share identical LED type (T1), material (black PVC), and compliance characteristics. The series designation reflects different base product numbers (ELM2-4/ELM2-5 versus ELM5-4), with ELM 5-485 offering a 0.485" length option.

Q: Which substitute offers the closest dimensional match to ELM 2-490?

A: ELM 5-485 at 0.485" (12.32mm) provides the closest dimensional proximity, with a variance of only 0.005" (0.13mm) from the original 0.490" specification.
