ELM 2-385 LED Standoff: Equivalent & Substitute Parts

Part Overview

The ELM 2-385 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.385" (9.78mm) length specification. The part maintains Active product status and is RoHS3 compliant, making it suitable for current production environments. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where dimensional and material tolerances permit.

Substitute Part Grouping Explanation

Substitute parts for the ELM 2-385 are identified based on the following criteria:

Primary Matching Parameters:

• LED Type: T1 (exact match required)
• Color: Black (exact match required)
• Mounting Style: Vertical (exact match required)
• RoHS Compliance: ROHS3 (minimum requirement)
• MSL Rating: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Length: ±0.010" tolerance band (0.375" to 0.395")
• Material: PVC or Nylon (both acceptable for T1 standoff applications)

The ELM 2-385 substitutes are limited to parts that maintain T1 LED compatibility, vertical mounting orientation, and black color specification. Length variations within the tolerance band accommodate minor dimensional differences that do not affect PCB assembly or LED seating. Material substitution between PVC and Nylon is permitted when both materials meet the application's thermal and chemical resistance requirements.

Engineering Selection Recommendations

ELM 5-390 Substitution: The ELM 5-390 is a direct parametric equivalent with a length of 0.390" (9.91mm), representing a +0.005" variance from the ELM 2-385 specification. Both parts share identical LED type (T1), color (Black), material (PVC), mounting style (Vertical), and compliance certifications (ROHS3, MSL 1). This substitute is suitable for applications where the minor length increase does not compromise PCB clearance or assembly constraints. The ELM 5-390 maintains Active product status with higher inventory availability (2242 Pcs).

H-201C Substitution: The H-201C presents a material and mounting style variation. While it maintains T1 LED compatibility, black color, and identical compliance ratings, it differs in two critical aspects: material composition (Nylon vs. PVC) and mounting orientation (Right Angle vs. Vertical). The length specification of 0.380" (9.65mm) represents a -0.005" variance. This substitute is applicable only in applications where right-angle mounting is acceptable and nylon material properties are compatible with the thermal and chemical environment. The H-201C carries significantly higher inventory (63104 Pcs).

Selection Criteria:

• Use ELM 5-390 when vertical mounting and PVC material are required with minimal length tolerance
• Use H-201C only when right-angle mounting orientation is compatible with the PCB layout and nylon material is acceptable
• All three parts meet current RoHS3 compliance and unlimited MSL storage requirements

Frequently Asked Questions (FAQ)

Q: Can the ELM 5-390 directly replace the ELM 2-385 in my assembly?

A: The ELM 5-390 is a direct substitute if your PCB design accommodates the +0.005" length increase (0.390" vs. 0.385"). Both parts are T1 LED standoffs with vertical mounting, black color, PVC material, and identical compliance certifications. Verify that the additional 0.005" height does not interfere with component clearance or solder joint formation.

Q: Why is the H-201C listed as a substitute if it has right-angle mounting?

A: The H-201C is included as a parametric equivalent because it shares the core T1 LED type, black color, and compliance requirements. However, its right-angle (RA) mounting orientation differs fundamentally from the vertical (SR VERT) style of the ELM 2-385. This substitute applies only to redesigned assemblies where right-angle orientation is acceptable.

Q: What is the significance of the length tolerance between these parts?

A: The three parts span a length range of 0.380" to 0.390" (9.65mm to 9.91mm), a 0.010" band. This variation affects PCB clearance, LED seating depth, and solder joint geometry. Verify your PCB design accommodates this range before selecting a substitute.

Q: Are all three parts RoHS3 compliant?

A: Yes. The ELM 2-385, ELM 5-390, and H-201C all carry ROHS3 Compliant certification, meeting current regulatory requirements for restricted substances.

Q: What is the difference between PVC and Nylon material in these standoffs?

A: Both PVC and Nylon are acceptable materials for T1 LED standoffs. PVC offers standard thermal and chemical resistance for general applications. Nylon provides enhanced mechanical strength and temperature stability. Material selection depends on your specific thermal environment and mechanical stress requirements.

Q: Does packaging type affect substitution compatibility?

A: All three parts are supplied in Bag packaging. Packaging type does not affect electrical or mechanical compatibility; it only influences handling and storage logistics.

Q: What does MSL 1 (Unlimited) mean for component storage?

A: MSL 1 (Unlimited) indicates these components have no moisture sensitivity restrictions. They can be stored indefinitely without desiccant protection or time-limited shelf life constraints, simplifying inventory management.
