ELM 4-450 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-450 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.450" (11.43mm) 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 with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain functional equivalence within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-450 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• Series: ELM 4 (maintains mechanical and electrical interface compatibility)
• LED Type: T1 (standardized form factor for 3MM 2-lead LEDs)
• Material: Black PVC (identical material specification)
• Configuration: Vertical mount, 3MM 2-lead (functional mounting orientation)
• RoHS Status: ROHS3 Compliant (regulatory requirement maintained)
• MSL Rating: 1 (Unlimited) (moisture sensitivity level compatibility)

Secondary Tolerance Parameter:

• Length: Mechanical dimension tolerance within the ELM 4 series specification range

The ELM 4-440 qualifies as a parametric equivalent because it maintains all primary compatibility criteria. The length differential (0.440" versus 0.450") represents a 0.010" (0.25mm) variation within the mechanical tolerance envelope of the ELM 4 series design.

Engineering Selection Recommendations

ELM 4-450 Primary Selection: The ELM 4-450 is the specified component for applications requiring the 0.450" (11.43mm) standoff length. Both the main part and substitute maintain Active product status with full ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility across all applications.

ELM 4-440 Substitute Selection: The ELM 4-440 serves as a parametric equivalent when the 0.010" (0.25mm) length reduction is mechanically acceptable within the application's tolerance stack. Both parts are manufactured by Bivar Inc. within the same ELM 4 series, ensuring identical electrical performance, mechanical interface compatibility, and regulatory compliance.

Selection between these parts is based on mechanical clearance requirements and available inventory. Both parts carry identical certifications and material specifications.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between ELM 4-450 and ELM 4-440?

A: The parts differ only in length specification. The ELM 4-450 measures 0.450" (11.43mm), while the ELM 4-440 measures 0.440" (11.18mm). All other electrical, mechanical, and regulatory parameters are identical.

Q: Can ELM 4-440 be used in place of ELM 4-450?

A: The ELM 4-440 is a parametric equivalent within the ELM 4 series. Substitution is valid when the 0.010" (0.25mm) length reduction does not violate application mechanical tolerances or clearance requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both ELM 4-450 and ELM 4-440 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Do both parts use the same material and color?

A: Yes. Both parts are constructed from black PVC material with identical color specification.

Q: What is the packaging format for these parts?

A: Both parts are supplied in bag packaging format.

Q: Are both parts currently in active production?

A: Yes. Both ELM 4-450 and ELM 4-440 maintain Active product status with Bivar Inc.
