ELM 4-475 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-475 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.475" (12.07mm) length. This component is constructed from black PVC material and accommodates 3MM 2-lead LED 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 tolerance flexibility necessitate alternative components that maintain functional equivalence within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the ELM 4-475 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• LED Type: T1 (fixed requirement)
• Material: Black PVC (fixed requirement)
• Configuration: 3MM 2-Lead Vertical Mount (fixed requirement)
• Manufacturer: Bivar Inc. (same manufacturer ecosystem)
• RoHS Compliance: ROHS3 Compliant (regulatory equivalence)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental equivalence)

Allowable Variation:

• Length tolerance: Components within the ELM series with length specifications of 0.475" to 0.485" are considered parametrically equivalent due to mechanical mounting flexibility in vertical standoff applications.

The ELM 5-485 substitute maintains all critical parameters while accommodating a 0.010" (0.25mm) length variation, which falls within acceptable mechanical tolerances for LED standoff mounting applications.

Engineering Selection Recommendations

ELM 4-475 Primary Selection: Select the ELM 4-475 when the exact 0.475" (12.07mm) length specification is required by design documentation or when inventory availability supports immediate procurement. This part maintains Active product status with 692 units in stock.

ELM 5-485 Substitute Selection: The ELM 5-485 is a valid substitute when the 0.010" (0.25mm) length increase is accommodated by the mechanical design envelope. Both parts maintain identical electrical characteristics, material composition, LED type, and regulatory compliance (ROHS3). The ELM 5-485 offers significantly higher inventory availability with 10,054 units in stock, supporting extended production runs and reducing lead time risk.

Compliance Equivalence: Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring equivalent environmental and reliability performance in production environments.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 4-475 and ELM 5-485?

A: The primary difference is the length specification. The ELM 4-475 measures 0.475" (12.07mm), while the ELM 5-485 measures 0.485" (12.32mm), representing a 0.010" (0.25mm) variation. All other parameters including LED type (T1), material (Black PVC), configuration (3MM 2-Lead Vertical Mount), and regulatory compliance (ROHS3) are identical.

Q: Can ELM 5-485 be used in place of ELM 4-475 in my design?

A: The ELM 5-485 can be used as a substitute if your mechanical design accommodates the 0.010" (0.25mm) additional length. Both parts are manufactured by Bivar Inc., use identical materials and LED configurations, and maintain equivalent regulatory compliance. Verify that the increased standoff height does not conflict with your PCB layout or component clearance requirements.

Q: Are there any electrical performance differences between these parts?

A: No electrical performance differences exist between these parts. Both are T1 LED standoffs with identical electrical characteristics, material properties, and regulatory certifications.

Q: What does ROHS3 compliance mean for these parts?

A: ROHS3 compliance indicates that both the ELM 4-475 and ELM 5-485 conform to the Restriction of Hazardous Substances Directive 3, restricting the use of specific hazardous materials in electrical and electronic equipment. This certification ensures equivalent environmental and safety performance.

Q: Why is inventory availability different between these parts?

A: The ELM 5-485 has higher inventory availability (10,054 units) compared to the ELM 4-475 (692 units). This difference reflects market demand patterns and manufacturing production schedules. Higher availability of the ELM 5-485 may support extended production timelines and reduce procurement risk.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates that both parts have no moisture sensitivity restrictions and do not require special moisture-controlled storage or handling procedures. These components can be stored and handled under standard environmental conditions without degradation.

Q: Are both parts available in the same packaging format?

A: Yes, both the ELM 4-475 and ELM 5-485 are supplied in Bag packaging, ensuring consistent handling and storage compatibility across your supply chain.
