ELM 5-650 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 5-650 is a T1 LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.650" (16.51mm) length. This component is designed for vertical mounting applications requiring precise LED positioning in 3MM configurations with 2-lead connections. 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 components that maintain functional equivalence within specified mechanical and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 5-650 is determined by the following critical parameters:

Primary Substitution Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Configuration: Vertical mount, 3MM, 2-lead (fixed requirement)
• Manufacturer: Bivar Inc. (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)

Allowable Variation:

• Length: Tolerance range of ±0.020" (±0.51mm) from the primary part specification

The ELM 5-650 has two identified substitutes: ELM 2-665 and ELM 2-17MM. Both parts satisfy the primary substitution criteria while operating within the allowable length tolerance band. The ELM 2-665 maintains a length of 0.665" (16.89mm), representing a +0.015" variance. The ELM 2-17MM operates at 0.670" (17.02mm), representing a +0.020" variance. Both substitutes preserve functional equivalence in vertical mounting applications where minor height variations do not compromise circuit board layout or component clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

ELM 2-665 Selection Criteria: The ELM 2-665 represents the closest dimensional match to the ELM 5-650, with a length variance of +0.015" (0.38mm). This substitute is appropriate for applications where minimal height deviation is required and component clearance margins are adequate. The part maintains identical RoHS3 compliance, MSL rating, and material specifications. Current inventory of 882 pieces supports production continuity.

ELM 2-17MM Selection Criteria: The ELM 2-17MM operates at the maximum allowable length variance of +0.020" (0.51mm) from the primary specification. This substitute is suitable for applications where the additional 0.020" height does not conflict with circuit board layout constraints or component spacing requirements. The part maintains full compliance with RoHS3 standards and MSL ratings. Highest current inventory availability at 1815 pieces provides extended supply security.

Compliance Basis: All three parts (ELM 5-650, ELM 2-665, ELM 2-17MM) are Active status products manufactured by Bivar Inc. with ROHS3 compliance certification. Selection between primary and substitute parts should be based on design layout requirements and inventory availability rather than functional or compliance considerations, as all parts meet identical regulatory and environmental standards.

Frequently Asked Questions (FAQ)

Q: What is the maximum allowable length difference between the ELM 5-650 and its substitutes? A: The allowable length tolerance is ±0.020" (±0.51mm). The ELM 2-665 operates at +0.015" variance, and the ELM 2-17MM operates at +0.020" variance, both within specification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. The ELM 5-650, ELM 2-665, and ELM 2-17MM are all ROHS3 compliant. The ELM 2-665 additionally carries REACH Unaffected status.

Q: Can the ELM 2-665 and ELM 2-17MM be used interchangeably with the ELM 5-650? A: Both parts are functionally equivalent within the specified length tolerance band. Selection depends on circuit board layout requirements and whether the additional height of each substitute accommodates design constraints.

Q: What is the Moisture Sensitivity Level for all three parts? A: All parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there packaging differences between the main part and substitutes? A: No. All three parts are supplied in Bag packaging format.

Q: Which substitute has the highest current inventory? A: The ELM 2-17MM maintains the highest inventory at 1815 pieces, compared to 992 pieces for the ELM 5-650 and 882 pieces for the ELM 2-665.

Q: Do the substitute parts use different base product numbers? A: Yes. The ELM 5-650 uses base product number ELM5-6, while ELM 2-665 and ELM 2-17MM use base product number ELM2-6 and ELM2-1 respectively. This reflects different product series within the Bivar Inc. LED standoff portfolio.
