ELM 4-930 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-930 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.930" (23.62mm) length. This component is constructed from black PVC material and accommodates 3MM LED packages with 2-lead configurations. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-930 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Primary Substitution Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• LED Package Size: 3MM (fixed requirement)
• Lead Configuration: 2LD (fixed requirement)
• Mounting Orientation: Vertical (fixed requirement)
• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance)

Allowable Variation:

• Length: Within 0.020" (0.51mm) tolerance of nominal 0.930" (23.62mm)

The ELM 5-23MM qualifies as a parametric equivalent because it maintains all fixed parameters while operating within the allowable length tolerance range.

Engineering Selection Recommendations

ELM 4-930 Primary Selection: Select the ELM 4-930 when the exact nominal length of 0.930" (23.62mm) is specified in the design documentation. This part is Active status with full ROHS3 compliance and maintains current manufacturing support from Bivar Inc.

ELM 5-23MM Substitute Selection: The ELM 5-23MM operates as a direct substitute when the ELM 4-930 is unavailable. The 0.020" (0.51mm) length variance falls within standard mechanical tolerances for LED standoff applications. Both parts share identical electrical and material specifications, Active product status, and ROHS3 compliance certification. The substitute maintains equivalent performance in vertical mounting configurations for T1 3MM 2-lead LED packages.

Compliance Verification: Both parts satisfy ROHS3 regulatory requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, confirming suitability for standard storage and handling conditions without desiccant requirements.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM be used directly in place of ELM 4-930 without design modification?

A: Yes. The ELM 5-23MM is a parametric equivalent with a length of 0.910" (23.11mm) compared to the ELM 4-930 at 0.930" (23.62mm). This 0.020" (0.51mm) difference is within standard mechanical tolerances for LED standoff applications and does not affect electrical performance or mechanical fit in standard PCB mounting configurations.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are passive mechanical standoffs for T1 LED packages. Electrical performance is determined by the LED component itself, not the standoff. The standoff provides only mechanical positioning and structural support.

Q: Do both parts require the same handling and storage procedures?

A: Yes. Both ELM 4-930 and ELM 5-23MM carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. Standard dry storage conditions are sufficient; desiccant packaging is not required.

Q: What is the basis for the length tolerance between these parts?

A: The 0.020" (0.51mm) variance between 0.930" and 0.910" represents a ±0.010" tolerance band, which is standard for injection-molded PVC standoff components in the LED mounting industry.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 4-930 and ELM 5-23MM are certified ROHS3 compliant, meeting all current regulatory requirements for restricted substance limitations.

Q: Can these parts be used interchangeably in existing production?

A: Yes, provided the design allows for the 0.020" length variance. If the PCB layout or mechanical assembly has tight height constraints, engineering review of the specific application is necessary to confirm the length difference does not impact form factor or clearance requirements.
