ERM 1-455 LED Standoff Equivalent and Substitute Parts

Part Overview

The ERM 1-455 is a 2 and 3 Lead LED Standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.455" (11.56mm) vertical mounting height. This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). LED standoffs serve as precision mechanical supports for light-emitting diode assemblies, enabling standardized mounting in universal PCB applications. Substitute parts become necessary when primary inventory is depleted, when design specifications allow for minor dimensional variations, or when supply chain constraints require alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The ERM 1-450 qualifies as a parametric equivalent to the ERM 1-455 based on the following substitution criteria:

Shared Critical Parameters:

• Manufacturer: Bivar Inc.
• Series: ERM 1
• LED Configuration: 2 and 3 Lead LEDs
• Material: Black PVC
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging: Bag

Primary Dimensional Difference:

• ERM 1-455: 0.455" (11.56mm) length
• ERM 1-450: 0.450" (11.43mm) length

The dimensional tolerance of 0.005" (0.13mm) between these parts falls within acceptable mechanical substitution parameters for universal LED standoff applications where design specifications permit minor mounting height variations.

Parameter Comparison

Engineering Selection Recommendations

Both the ERM 1-455 and ERM 1-450 maintain identical active product status and ROHS3 compliance certifications. Selection between these parts should be determined by application-specific mounting height requirements. The ERM 1-455 at 0.455" length provides additional standoff height, while the ERM 1-450 at 0.450" length offers 0.005" reduced clearance. Both components share identical moisture sensitivity rating and regulatory classifications, confirming compliance equivalence across industrial and commercial applications. Inventory availability and procurement lead times are valid secondary selection criteria.

Frequently Asked Questions (FAQ)

Q: Can ERM 1-450 be used as a direct drop-in replacement for ERM 1-455?

A: The ERM 1-450 functions as a parametric equivalent with a 0.005" (0.13mm) shorter mounting height. Direct substitution is appropriate when application design specifications permit this dimensional variance or when the reduced height does not impact circuit board layout, component clearance, or system assembly requirements.

Q: Are there electrical performance differences between these parts?

A: Both parts support identical 2 and 3 Lead LED configurations. Electrical performance is determined by the LED component mounted in the standoff, not by the standoff material or height. The black PVC construction and base materials are identical across both parts.

Q: Do regulatory certifications differ between ERM 1-455 and ERM 1-450?

A: Both parts maintain identical ROHS3 compliance status, moisture sensitivity level (MSL 1), and regulatory classifications (ECCN EAR99, HTSUS 3926.90.9985). Regulatory equivalence is confirmed across all certifications.

Q: What factors should determine part selection?

A: Selection criteria are limited to application-specific mounting height tolerance requirements and inventory availability. The ERM 1-455 provides maximum standoff height at 0.455", while the ERM 1-450 provides a 0.005" reduction. All other parameters remain identical, eliminating additional selection variables.

Q: Are packaging and inventory considerations relevant to substitution?

A: Both parts use identical bag packaging suitable for component handling and storage. Current inventory levels may influence procurement decisions, with the ERM 1-450 showing significantly higher stock availability (15,251 pcs vs. 832 pcs).
