ELM 5-145

Part Overview

The ELM 5-145 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component consists of a black PVC standoff with a 0.145" (3.68mm) height, accommodating T1 LED packages with 2 leads. The part is currently in active product status and ROHS3 compliant, making it suitable for modern electronic assemblies. Alternative models are evaluated when specific height requirements differ or when supply chain optimization necessitates cross-series compatibility within the ELM product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELM 5-145 is permissible based on the following key parameters: LED type (T1), material composition (black PVC), lead count (2 leads), RoHS compliance (ROHS3), and moisture sensitivity level (MSL 1). Two substitution categories exist within the ELM product family:

Same-Series, Same-Height Substitutes: The ELM 4-145 provides equivalent functionality within the same height specification (0.145"), differing only in series designation while maintaining all critical electrical and mechanical parameters.

Cross-Series, Alternative-Height Substitutes: The ELM 5-150 and ELM 4-150 maintain identical material, LED type, and compliance specifications but specify a 0.150" (3.81mm) height. These parts are substitutable only when application PCB layout and assembly clearances accommodate the increased standoff height.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring continued manufacturing support and regulatory alignment with modern electronic assembly standards. The ELM 4-145 represents a direct functional equivalent with identical geometric and material specifications, providing the primary substitution option without assembly redesign.

The ELM 5-150 and ELM 4-150 are functionally equivalent from an electrical and environmental compliance perspective but require PCB design validation due to the 0.005" (0.13mm) height differential. This geometric variance may impact clearance margins, solder joint formation, and LED placement relative to substrate surfaces. Selection between ELM 5 and ELM 4 series alternatives depends on supply availability and design constraints, as both series share identical material, compliance, and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can the ELM 4-145 be substituted for ELM 5-145 without design modifications? A: Yes. The ELM 4-145 maintains identical height (0.145"), material (black PVC), LED type (T1), lead count, RoHS compliance, and MSL rating. No assembly or layout changes are required.

Q: What is the primary difference between the ELM 5-145 and the ELM 5-150? A: The ELM 5-150 specifies 0.150" height versus 0.145" for the ELM 5-145. All other electrical and material parameters are identical. Height differences may affect PCB assembly clearances.

Q: Are ELM 4 series parts mechanically compatible with ELM 5 series designs? A: Yes, for parts sharing the same height specification. ELM 4-145 and ELM 5-145 are mechanically and electrically interchangeable. ELM 4-150 and ELM 5-150 are interchangeable with each other but not with the 0.145" variants.

Q: What compliance certifications apply to all substitute parts? A: All parts are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level), ECCN classification EAR99, and HTSUS code 3926.90.9985.

Q: Can I use a 0.150" height standoff in place of a 0.145" standoff? A: Only if PCB design accommodates the 0.005" additional height. The LED-to-substrate spacing will increase by this amount, potentially affecting light diffusion angles and component positioning within the assembly envelope.
