ELM 2-245 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-245 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.245" (6.22mm) length. This component is classified as an active product and serves as a mechanical mounting solution for T1 LED assemblies in vertical orientation. Substitute parts become necessary when the primary part experiences inventory constraints, extended lead times, or when design specifications permit tolerance variations within the allowed mechanical and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the ELM 2-245 is based on the following allowed parameters:

Primary Substitution Criteria:

• LED Type: T1 (all substitutes maintain this specification)
• Orientation: Vertical mounting (SR VERT configuration)
• Color: Black (consistent across all alternatives)
• RoHS Compliance: ROHS3 Compliant (all substitutes meet this requirement)
• MSL Rating: 1 (Unlimited) (all substitutes maintain this rating)

Secondary Substitution Criteria:

• Length Tolerance: Mechanical length variations within 0.235" to 0.250" (5.97mm to 6.35mm) are acceptable
• Material: Both PVC and Nylon constructions are interchangeable within this product category

The three substitute parts (ELM 4-6MM, ELM 5-235, and H-131C-1-120) meet all primary criteria and fall within the acceptable length tolerance range. Material variation between PVC and Nylon does not affect functional compatibility for T1 LED standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (ELM 2-245): Use the ELM 2-245 when exact dimensional specifications are required and inventory availability permits. This part maintains the nominal 0.245" (6.22mm) length specification.

Secondary Selection (ELM 4-6MM): The ELM 4-6MM provides a substitute with 0.010" (0.12mm) shorter length (0.240" vs. 0.245"). This part is suitable when the application tolerates the reduced length and higher inventory availability is prioritized. Material composition remains PVC.

Tertiary Selection (ELM 5-235): The ELM 5-235 offers the shortest length at 0.235" (5.97mm), representing a 0.010" (0.25mm) reduction from the primary part. This substitute is appropriate for applications with flexible length requirements and provides the highest inventory availability (20,398 pcs).

Alternative Selection (H-131C-1-120): The H-131C-1-120 provides a Nylon construction alternative with 0.250" (6.35mm) length, representing a 0.005" (0.13mm) increase from the primary part. This substitute is suitable when material variation is acceptable and Nylon properties are compatible with the application environment.

All substitutes maintain ROHS3 compliance, MSL Rating 1, and T1 LED compatibility. Selection should be based on dimensional tolerance requirements and material compatibility with the end application.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-6MM be used as a direct replacement for ELM 2-245?

A: Yes. The ELM 4-6MM is a parametric equivalent with a length of 0.240" (6.10mm) compared to the ELM 2-245 at 0.245" (6.22mm). The 0.010" (0.12mm) difference falls within acceptable mechanical tolerance for T1 LED standoff applications. Both parts maintain identical LED type, color, material (PVC), RoHS compliance, and MSL rating.

Q: What is the maximum length variation among substitute parts?

A: The maximum length variation across all substitutes is 0.015" (0.38mm), ranging from 0.235" (ELM 5-235) to 0.250" (H-131C-1-120). This variation is within the mechanical tolerance envelope for T1 LED standoff mounting applications.

Q: Does material substitution between PVC and Nylon affect compatibility?

A: Material substitution between PVC and Nylon does not affect functional compatibility for T1 LED standoff applications. Both materials are used interchangeably within this product category. Material selection should be based on environmental exposure, temperature requirements, and mechanical stress conditions of the specific application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts (ELM 4-6MM, ELM 5-235, and H-131C-1-120) are ROHS3 compliant, matching the compliance status of the primary ELM 2-245 part.

Q: What is the MSL rating for all parts in this substitution group?

A: All parts in this substitution group maintain MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part offers the highest inventory availability?

A: The ELM 5-235 provides the highest inventory availability with 20,398 pieces in stock, compared to 987 pieces for the primary ELM 2-245 part.

Q: Can H-131C-1-120 be used in applications requiring PVC material specifically?

A: No. The H-131C-1-120 uses Nylon construction rather than PVC. If PVC material is a specific requirement, select from ELM 2-245, ELM 4-6MM, or ELM 5-235.
