ELM 1-550 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-550 is a T1 3/4 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.550" (13.97mm) length specification. 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 parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the ELM 1-550 are identified based on strict parameter matching within the ELM 1 series. The primary substitution criterion is the LED type (T1 3/4), material composition (PVC), and color (Black), which must remain constant to ensure mechanical and functional compatibility.

The length parameter represents the only variable dimension among qualified substitutes. The ELM 1-545 substitute part differs from the main part by 0.005" (0.13mm) in length specification. This dimensional variance falls within the tolerance range for standoff applications where minor height adjustments do not compromise circuit board clearance or component mounting integrity.

All substitute parts must maintain:

• Identical LED type classification (T1 3/4)
• Identical material specification (PVC)
• Identical color designation (Black)
• Identical series designation (ELM 1)
• Identical RoHS compliance status (ROHS3 Compliant)
• Identical MSL rating (1 - Unlimited)

Parameter Comparison

Engineering Selection Recommendations

ELM 1-550 Primary Selection: Use when the exact 0.550" (13.97mm) length specification is required by circuit board design parameters or when this part number is specified in engineering documentation.

ELM 1-545 Substitute Selection: This part is functionally equivalent for applications where a 0.005" (0.13mm) reduction in standoff height is acceptable. Both parts maintain identical compliance certifications (ROHS3), identical moisture sensitivity ratings (MSL 1), and identical regulatory classifications (ECCN EAR99, HTSUS 8547.20.0000).

The substitute part carries significantly higher inventory availability (20,121 pieces versus 973 pieces), making it suitable for high-volume production scenarios or when lead time optimization is required. Both parts are classified as Active products, ensuring continued manufacturer support and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-545 be used as a direct replacement for ELM 1-550?

A: The ELM 1-545 is a parametric equivalent within the ELM 1 series with a 0.005" (0.13mm) shorter length. Substitution is valid when circuit board design tolerances accommodate this dimensional variance. Both parts share identical LED type (T1 3/4), material (PVC), color (Black), and all regulatory compliance specifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: LED type (T1 3/4), material composition (PVC), color (Black), series designation (ELM 1), RoHS compliance status (ROHS3), and MSL rating (1 - Unlimited). Length represents the only variable parameter among qualified substitutes.

Q: Are there any compliance or certification differences between these parts?

A: No. Both ELM 1-550 and ELM 1-545 maintain identical RoHS3 compliance status, identical MSL ratings (1 - Unlimited), identical ECCN classification (EAR99), and identical HTSUS codes (8547.20.0000).

Q: What is the inventory status of each part?

A: ELM 1-550 has 973 pieces in stock. ELM 1-545 has 20,121 pieces in stock. Both are classified as New Original inventory.

Q: How does the 0.005" length difference affect application compatibility?

A: The length variance of 0.005" (0.13mm) represents a 0.09% dimensional change relative to the main part specification. Compatibility depends on circuit board design clearance requirements and mechanical mounting constraints specific to the application.

Q: Are both parts actively manufactured?

A: Yes. Both ELM 1-550 and ELM 1-545 maintain Active product status, indicating current manufacturing support and supply chain availability from Bivar Inc.
