ELM 7-320 Equivalent & Substitute Parts

Part Overview

The ELM 7-320 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.320" (8.13mm) height. This component is actively produced and maintains ROHS3 compliance. Alternative models may be required due to inventory availability, design revisions, or specific mechanical clearance requirements in applications where the exact part is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELM 7-320 is determined by the following critical parameters:

• LED Type: Must be T1
• Color: Black
• Material: PVC
• Length tolerance: Within manufacturing specifications for 0.315" to 0.320" range
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• Manufacturer: Bivar Inc.

The three identified substitute parts maintain compatibility across these parameters. Length variations between 0.315" (8.00mm) and 0.320" (8.13mm) are mechanically interchangeable for standard PCB mounting applications where the standoff height is non-critical to circuit operation.

Parameter Comparison

Engineering Selection Recommendations

All four parts are manufactured by Bivar Inc. and maintain Active product status with full ROHS3 compliance. The ELM 2-320 is the primary direct substitute, sharing identical length specifications (0.320") with the ELM 7-320 while differing only in series designation. The ELM 2-315 and ELM 4-315 introduce a 0.005" (0.13mm) height reduction, which is acceptable where mechanical clearance permits this tolerance variation.

Selection between these alternatives should be based on:

• Specific PCB design constraints requiring exact height matching
• Inventory availability of the preferred part number
• Series designation requirements defined by original equipment design specifications

Frequently Asked Questions (FAQ)

Q: Can ELM 2-315 be used in place of ELM 7-320? A: Yes. Both parts share identical T1 LED type, black PVC material, and ROHS3 compliance. The 0.005" (0.13mm) height difference between 0.320" and 0.315" is within standard mechanical tolerances for LED standoff applications and interchangeable for most PCB designs.

Q: What is the primary difference between ELM 7-320 and ELM 2-320? A: These parts are parametrically equivalent with identical length (0.320"), LED type (T1), color (black), and material (PVC). The distinction is the series designation (ELM 7 vs. ELM 2), indicating different product families within the Bivar Inc. portfolio.

Q: Are all substitutes ROHS compliant? A: All identified substitute parts (ELM 2-320, ELM 2-315, ELM 4-315) meet ROHS3 compliance standards, matching the original ELM 7-320 part.

Q: How does the 0.315" length compare to the 0.320" specification? A: The 0.315" length represents a 0.005" (0.13mm) reduction from the 0.320" height. This variation is within standard manufacturing tolerances and is mechanically interchangeable for standard PCB mounting applications. Height-critical designs should confirm clearance compatibility.

Q: What inventory availability exists for substitutes? A: The following inventory levels are current: ELM 2-320 (26,182 units), ELM 2-315 (7,562 units), and ELM 4-315 (4,972 units), providing multiple sourcing options.
