ELM 4-8MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-8MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.310" (7.87mm) length and accommodates T1 LED packages with 2-lead configurations. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to support procurement flexibility, inventory optimization, and supply chain continuity for applications requiring T1 LED standoff mounting solutions with compatible dimensional and material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-8MM are qualified based on the following criteria:

Primary Substitution Parameters:

• LED Type: T1 (all substitutes maintain T1 compatibility)
• Material: Black PVC (consistent across all alternatives)
• Lead Configuration: 2-Lead (maintained for circuit compatibility)
• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• Product Status: Active (all substitutes in current production)
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)
• Moisture Sensitivity Level: MSL 1 (storage and handling equivalence)

Dimensional Tolerance Consideration: Substitute parts vary in length specification within the range of 0.310" to 0.320" (7.87mm to 8.13mm). These dimensional variations fall within acceptable mechanical tolerances for T1 LED standoff mounting applications where vertical spacing accommodates minor length differences.

The three identified substitutes (ELM 2-315, ELM 2-320, ELM 4-315) maintain functional equivalence through shared core specifications while offering alternative inventory availability and series options.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-315 Selection Criteria: The ELM 2-315 provides a direct functional substitute with 0.315" (8.00mm) length specification. This part maintains ELM series compatibility while offering higher inventory availability (7,562 units). Selection is appropriate where the 0.005" (0.13mm) length increase accommodates circuit board layout requirements.

ELM 2-320 Selection Criteria: The ELM 2-320 represents the longest available substitute at 0.320" (8.13mm). This part offers maximum inventory availability (26,182 units) and is suitable for applications requiring extended vertical standoff height. The 0.010" (0.25mm) length increase from the primary part must be evaluated against PCB spacing constraints.

ELM 4-315 Selection Criteria: The ELM 4-315 maintains the ELM 4 series designation while providing 0.315" (8.00mm) length. This substitute preserves series consistency with the primary part and offers intermediate inventory levels (4,972 units). Selection is appropriate for applications prioritizing series alignment with existing component specifications.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental handling equivalence with the primary ELM 4-8MM part.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 4-8MM and its substitutes?

A: The primary difference is length specification. The ELM 4-8MM measures 0.310" (7.87mm), while substitutes range from 0.315" to 0.320" (8.00mm to 8.13mm). All parts maintain identical LED type (T1), material (Black PVC), lead configuration (2-Lead), and compliance ratings.

Q: Can ELM 2-315 and ELM 2-320 be used interchangeably with ELM 4-8MM?

A: Yes, within dimensional tolerance limits. Both parts share core specifications (T1 LED type, Black PVC material, 2-Lead configuration, RoHS3 compliance, MSL 1 rating). The length difference of 0.005" to 0.010" must be evaluated against specific PCB layout and vertical spacing requirements.

Q: What is the difference between ELM 2 and ELM 4 series standoffs?

A: The provided data indicates both series maintain identical functional specifications for T1 LED standoff applications. Series designation reflects internal Bivar Inc. product line organization. Both series are suitable for equivalent mounting applications.

Q: How does inventory availability affect part selection?

A: Inventory levels vary significantly: ELM 4-8MM (1,070 units), ELM 2-315 (7,562 units), ELM 2-320 (26,182 units), and ELM 4-315 (4,972 units). Higher inventory availability may support extended production runs or reduce lead time risk. Selection should balance dimensional requirements with supply chain considerations.

Q: Are all substitutes RoHS3 compliant?

A: Yes. The ELM 4-8MM and all three substitute parts (ELM 2-315, ELM 2-320, ELM 4-315) are RoHS3 compliant, ensuring regulatory equivalence for applications subject to RoHS requirements.

Q: What does MSL 1 rating mean for these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no special moisture control requirements during storage or handling. All substitute parts share this MSL 1 rating with the primary part.

Q: Can length differences affect circuit performance?

A: Length differences of 0.005" to 0.010" are mechanical specifications affecting physical standoff height. Electrical performance of T1 LED mounting is not affected by these dimensional variations. PCB layout and component spacing must be verified during design integration.
