ELM 4-24MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-24MM is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a length of 0.940" (23.90mm). This component is classified as an active product and is RoHS3 compliant. LED standoffs are mechanical mounting solutions that position light-emitting diodes at precise vertical heights in electronic assemblies. Substitute parts are identified when equivalent electrical and mechanical parameters allow functional interchangeability within specified tolerances.

Substitute Part Grouping Explanation

The ELM 5-23MM is established as a substitute for the ELM 4-24MM based on the following equivalence criteria:

• LED Type Compatibility: Both parts utilize T1 LED specifications, ensuring identical mounting and electrical interface requirements.
• Material Specification: Both parts employ black PVC construction, maintaining material compatibility and environmental resistance properties.
• Manufacturer Origin: Both parts are manufactured by Bivar Inc., ensuring consistent manufacturing standards and quality assurance protocols.
• Compliance Alignment: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL 1), confirming regulatory and handling equivalence.
• Length Tolerance: The ELM 5-23MM measures 0.910" (23.11mm), representing a 0.030" (0.79mm) dimensional variation from the ELM 4-24MM's 0.940" (23.90mm). This variance falls within acceptable mechanical tolerances for standoff applications where precise vertical spacing is achievable through assembly design.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-24MM and ELM 5-23MM are active products with equivalent compliance certifications and handling requirements. Selection between these parts should be determined by the specific vertical spacing requirements of the target application. The ELM 4-24MM provides a longer standoff height at 0.940" (23.90mm), while the ELM 5-23MM offers a reduced height of 0.910" (23.11mm). Both parts satisfy ROHS3 compliance requirements and maintain identical Moisture Sensitivity Level specifications, making either part suitable for applications where regulatory compliance is mandated.

Frequently Asked Questions (FAQ)

Q: Are the ELM 4-24MM and ELM 5-23MM mechanically interchangeable? A: Both parts feature identical T1 LED mounting specifications and black PVC material composition. Interchangeability depends on the vertical spacing requirements of the PCB assembly design. The 0.030" (0.79mm) length difference must be accommodated within the mechanical layout.

Q: Do both parts meet the same environmental and compliance standards? A: Yes. Both parts are ROHS3 compliant and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings, indicating equivalent handling and storage requirements.

Q: Which part should be selected for a new design? A: Selection should be based on the required vertical spacing distance between the LED mounting surface and the circuit board. Verify the mechanical clearance specifications of your assembly design before part selection.

Q: Are there packaging differences between these parts? A: Both parts are supplied in bag packaging. Verify minimum order quantities and lead times with your supplier for procurement planning.

Q: Can the ELM 5-23MM replace an ELM 4-24MM in existing inventory? A: Substitution is permissible only when the assembly design accommodates the 0.030" (0.79mm) reduction in standoff height. Review mechanical clearance drawings to confirm compatibility.
