ELM 4-685 Equivalent & Substitute Parts

Part Overview

The ELM 4-685 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.685" (17.40mm) 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 options that maintain equivalent electrical and mechanical performance within specified tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-685 is determined by strict adherence to the following parameters: LED type (T1), material composition (black PVC), mounting orientation (vertical), LED package size (3MM), lead configuration (2-lead), and manufacturer (Bivar Inc.). The substitute parts ELM 2-665 and ELM 2-17MM meet these core electrical and mechanical criteria. Length variation is permitted within the tolerance range of 0.665" to 0.685" (16.89mm to 17.40mm), as this dimension falls within acceptable mechanical clearance for standard PCB mounting applications. Both substitute parts maintain identical RoHS3 compliance, MSL rating, and material specifications as the primary part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ELM 4-685, ELM 2-665, and ELM 2-17MM—maintain Active product status and ROHS3 compliance, confirming suitability for current production and regulatory requirements. The ELM 4-685 represents the primary specification with a length of 0.685" (17.40mm). The ELM 2-665 provides a substitute option with a length of 0.665" (16.89mm), representing a 0.020" (0.51mm) reduction. The ELM 2-17MM offers an intermediate length of 0.670" (17.02mm), representing a 0.015" (0.38mm) reduction from the primary part. Length variations across this range remain within standard mechanical tolerances for vertical LED standoff applications. Selection between these parts depends on specific PCB layout requirements and available inventory. All parts share identical electrical characteristics, material composition, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-665 and ELM 2-17MM be used interchangeably with ELM 4-685?

A: Yes, within the specified length tolerance range. All three parts share identical LED type (T1), material (black PVC), mounting orientation (vertical), package size (3MM), lead configuration (2-lead), and compliance ratings. Length variations of 0.020" (0.51mm) and 0.015" (0.38mm) respectively fall within acceptable mechanical clearance for standard vertical mounting applications.

Q: What is the maximum length variation between substitute parts?

A: The maximum length variation across all three parts is 0.020" (0.51mm), occurring between the ELM 4-685 (0.685") and ELM 2-665 (0.665"). This variation is within standard PCB mounting tolerances for LED standoff applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The ELM 4-685, ELM 2-665, and ELM 2-17MM are all ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current regulatory requirements for production environments.

Q: Do substitute parts have different packaging specifications?

A: All parts are supplied in Bag packaging format. Inventory availability differs: ELM 4-685 has 704 pieces, ELM 2-665 has 882 pieces, and ELM 2-17MM has 1815 pieces in stock.

Q: What determines substitution eligibility for LED standoff parts?

A: Substitution is determined by matching LED type, material composition, mounting orientation, LED package size, lead configuration, and manufacturer. Length variations within the 0.665" to 0.685" range are acceptable for mechanical compatibility.
