ERM 1-440 LED Standoff Equivalent & Substitute Parts

Part Overview

The ERM 1-440 is a 2 and 3 Lead LED standoff manufactured by Bivar Inc., featuring a black PVC construction with a 0.440" (11.18mm) vertical height. This component is designed for universal LED mounting applications and maintains Active product status. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific height specifications necessitate alternative components within the ERM 1 series that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the ERM 1 series are classified based on the following allowable parameters:

Substitution Criteria:

• Series designation (ERM 1)
• LED configuration (2 and 3 Lead LEDs)
• Material composition (Black PVC)
• RoHS compliance level (ROHS3 Compliant)
• Moisture Sensitivity Level (MSL 1)
• Packaging format (Bag)

Variable Parameter:

• Length/Height specification (0.440" to 0.450")

The ERM 1-450 is classified as a parametric equivalent because it maintains all core electrical and mechanical specifications while varying only in vertical height by 0.010" (0.25mm). This dimensional variance accommodates different PCB layout requirements and LED mounting heights within the same universal mounting platform.

Engineering Selection Recommendations

ERM 1-440 Selection Criteria:

• Applications requiring 0.440" (11.18mm) vertical standoff height
• PCB designs with specific LED mounting height constraints at 11.18mm
• Active product status with established supply chain

ERM 1-450 Selection Criteria:

• Applications requiring 0.450" (11.43mm) vertical standoff height
• PCB designs with specific LED mounting height constraints at 11.43mm
• Higher inventory availability (15,251 Pcs vs. 967 Pcs)
• Active product status with established supply chain

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage environments. Selection between ERM 1-440 and ERM 1-450 is determined solely by the required vertical height specification for the LED mounting application.

Frequently Asked Questions (FAQ)

Q: Can ERM 1-450 be used as a direct replacement for ERM 1-440?

A: ERM 1-450 is a parametric equivalent with identical electrical and mechanical specifications except for height. Substitution is valid only if the application tolerates a 0.010" (0.25mm) increase in vertical standoff height. PCB layout and LED clearance requirements must be verified against the specific application.

Q: What are the core compatibility parameters for ERM 1 series substitution?

A: Core compatibility parameters include: Series designation (ERM 1), LED configuration (2 and 3 Lead), material (Black PVC), RoHS compliance (ROHS3), and MSL rating (1). Height is the only variable parameter within the substitution group.

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

A: Yes. Both ERM 1-440 and ERM 1-450 are supplied in Bag packaging, maintaining consistent handling and storage requirements.

Q: What is the inventory status difference between these parts?

A: ERM 1-440 has 967 Pcs in stock, while ERM 1-450 has 15,251 Pcs in stock. Availability may influence selection when lead time is a consideration.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both ERM 1-440 and ERM 1-450 are ROHS3 Compliant with MSL 1 (Unlimited) rating, meeting identical regulatory and environmental requirements.
