ELM 4-680 Equivalent & Substitute Parts

Part Overview

The ELM 4-680 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.680" (17.27mm) 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 standoff heights while maintaining functional compatibility within the T1 LED mounting category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-680 are identified based on strict parametric equivalence within the T1 LED standoff category. The primary substitution criteria are:

Mandatory Matching Parameters:

• LED Type: T1 (fixed)
• Material: Black PVC (fixed)
• Mounting Orientation: Vertical (fixed)
• Lead Configuration: 2-Lead (fixed)
• Manufacturer: Bivar Inc. (fixed)
• RoHS Status: ROHS3 Compliant (fixed)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed)

Variable Parameter (Substitution Basis):

• Length: Tolerance range 0.665" to 0.680" (16.89mm to 17.27mm)

The ELM 4-680 substitutes are limited to parts within the ELM 2 series that maintain all fixed parameters while accommodating minor length variations. This length variance of approximately 0.015" (0.38mm) falls within acceptable mechanical tolerances for vertical LED standoff applications where precise height matching is not critical to circuit board layout.

Parameter Comparison

Engineering Selection Recommendations

ELM 4-680 (Primary Selection) The ELM 4-680 is the specified part number and maintains the longest standoff height at 0.680" (17.27mm). Selection of this part is appropriate when the original design height specification is required and inventory availability permits.

ELM 2-17MM (Preferred Substitute) The ELM 2-17MM provides the closest dimensional match to the ELM 4-680 with a length of 0.670" (17.02mm), representing a variance of only 0.010" (0.25mm). This part maintains all compliance certifications and material specifications. Current inventory of 1815 pieces provides superior availability. This substitute is appropriate when minor height reduction is acceptable within circuit board layout tolerances.

ELM 2-665 (Secondary Substitute) The ELM 2-665 offers a length of 0.665" (16.89mm), representing a variance of 0.015" (0.38mm) from the primary part. This part maintains all compliance certifications and material specifications. Current inventory of 882 pieces is available. This substitute is appropriate when maximum height reduction is acceptable and the ELM 2-17MM is unavailable.

All three parts are Active products with ROHS3 compliance and MSL 1 rating, ensuring suitability for current production and long-term reliability.

Frequently Asked Questions (FAQ)

Q: What is the maximum allowable length variance between the ELM 4-680 and its substitutes?

A: The substitute parts range from 0.665" to 0.680" in length, representing a maximum variance of 0.015" (0.38mm). This variance is within the mechanical tolerance band for T1 LED standoff applications where precise height matching is not a critical design parameter.

Q: Are all substitute parts manufactured by the same company?

A: Yes. The ELM 4-680 and both substitute parts (ELM 2-665 and ELM 2-17MM) are manufactured by Bivar Inc., ensuring consistent material quality and manufacturing standards.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), ensuring equivalent environmental and regulatory compliance for production use.

Q: What is the difference between the ELM 2-665 and ELM 2-17MM substitutes?

A: The primary difference is length. The ELM 2-17MM measures 0.670" (17.02mm), while the ELM 2-665 measures 0.665" (16.89mm). Both maintain identical material composition, LED type, lead configuration, and compliance status. The ELM 2-17MM provides closer dimensional proximity to the original ELM 4-680 specification.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Substitution is possible when the circuit board layout accommodates the length variance. The ELM 2-17MM (0.670") is the closest match and presents minimal height difference. The ELM 2-665 (0.665") introduces greater height reduction and requires verification that the reduced standoff height does not interfere with circuit board clearance requirements or component placement constraints.

Q: What packaging format is used for all three parts?

A: All three parts are supplied in Bag packaging, maintaining consistent handling and storage requirements across the product line.
