ELM 4-16MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-16MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.630" (16.00mm) 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 with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent functional performance can be achieved through alternative models within the same product series while maintaining compliance with electrical, mechanical, and environmental specifications.

Substitute Part Grouping Explanation

The ELM 4-16MM qualifies ELM 4-600 as a parametric equivalent based on the following substitution criteria:

Matching Parameters:

• LED Type: Both utilize T1 LED packages
• Material Composition: Both constructed from black PVC
• Color: Both black
• LED Package Size: Both accommodate 3mm packages
• Lead Configuration: Both feature 2-lead designs
• Product Series: Both belong to ELM 4 series
• RoHS Compliance: Both ROHS3 compliant
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• Manufacturer: Both manufactured by Bivar Inc.
• Packaging: Both supplied in bag format

Distinguishing Parameter:

• Length: ELM 4-16MM measures 0.630" (16.00mm); ELM 4-600 measures 0.600" (15.24mm)

The length differential of 0.030" (0.76mm) represents the primary mechanical distinction between these parts. Substitution suitability depends on application-specific height requirements and available mounting clearance.

Parameter Comparison

Engineering Selection Recommendations

Both ELM 4-16MM and ELM 4-600 maintain Active product status with full ROHS3 compliance and identical environmental ratings. Selection between these parts is determined by mechanical height requirements within the application assembly.

ELM 4-16MM Selection Criteria:

• Applications requiring 0.630" (16.00mm) standoff height
• Designs with adequate vertical clearance for the longer standoff
• Assemblies where the additional 0.030" height provides functional benefit

ELM 4-600 Selection Criteria:

• Applications requiring 0.600" (15.24mm) standoff height
• Space-constrained designs with limited vertical clearance
• Assemblies where the shorter standoff accommodates mechanical constraints

Both parts deliver equivalent electrical and environmental performance. The substitution decision is purely mechanical, based on available mounting space and design height specifications.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-600 directly replace ELM 4-16MM in all applications?

A: Direct replacement depends on application height requirements. The 0.030" (0.76mm) length difference must be evaluated against available vertical clearance and design specifications. Both parts are electrically and environmentally equivalent.

Q: Are there electrical performance differences between these standoffs?

A: No. Both parts are passive mechanical components with identical LED accommodation specifications (T1, 3mm, 2-lead). Electrical performance is determined by the LED package, not the standoff.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ELM 4-16MM and ELM 4-600 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What is the material composition of both standoffs?

A: Both standoffs are constructed from black PVC material, providing identical mechanical and thermal properties.

Q: Are packaging quantities the same for both parts?

A: Both parts are supplied in bag packaging format. Current inventory shows 1125 pieces for ELM 4-16MM and 1058 pieces for ELM 4-600. Packaging quantities per bag should be confirmed with the supplier.

Q: Can these standoffs be used interchangeably in PCB designs?

A: Interchangeability is limited to applications where the 0.030" height difference does not affect circuit board layout, component clearance, or mechanical assembly. PCB footprints and mounting hole spacing must accommodate both standoff lengths.

Q: What is the base product number relationship?

A: ELM 4-16MM uses base product number ELM4-1, while ELM 4-600 uses base product number ELM4-6. These designations indicate different length variants within the ELM 4 series.
