ELM 4-3.5MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 4-3.5MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.140" (3.56mm) length. This component is constructed from black PVC material and accommodates two-lead 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 specific application geometry necessitate alternative standoff heights within the ELM 4 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the ELM 4 series is determined by the following critical parameters:

Substitution Criteria:

• Manufacturer: Bivar Inc. (same manufacturer required)
• Series: ELM 4 (same product series)
• LED Type: T1 (identical LED form factor)
• Material: Black PVC (identical material composition)
• Lead Configuration: 2-Lead (identical electrical configuration)
• Mounting Style: Vertical (identical orientation)
• RoHS Status: ROHS3 Compliant (equivalent compliance level)
• Moisture Sensitivity Level: 1 (Unlimited) (identical MSL rating)

Variable Parameter:

• Length: Standoff height may vary within the ELM 4 series to accommodate different PCB-to-LED clearance requirements

The ELM 4-145 substitute part maintains all critical parameters while providing an alternative length specification of 0.145" (3.68mm) compared to the primary part's 0.140" (3.56mm).

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-3.5MM and ELM 4-145 maintain Active product status with ROHS3 compliance and identical Moisture Sensitivity Level ratings. Selection between these parts is determined by the specific standoff height requirement for the application:

• ELM 4-3.5MM is specified when a 0.140" (3.56mm) standoff height is required for PCB-to-LED clearance.
• ELM 4-145 is specified when a 0.145" (3.68mm) standoff height is required for PCB-to-LED clearance.

The 0.005" (0.12mm) height differential between these parts accommodates varying PCB thicknesses and component layout constraints. Both parts are manufactured by Bivar Inc. within the same product series and share identical electrical, material, and compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-145 be used as a direct replacement for ELM 4-3.5MM?

A: ELM 4-145 is a substitute part within the same series with identical electrical and material specifications. The primary difference is the standoff length: 0.145" (3.68mm) versus 0.140" (3.56mm). Substitution is valid only when the application design accommodates the 0.005" (0.12mm) height increase.

Q: What parameters must remain identical for substitution within the ELM 4 series?

A: Manufacturer (Bivar Inc.), series designation (ELM 4), LED type (T1), material (Black PVC), lead configuration (2-Lead), mounting style (Vertical), RoHS compliance level (ROHS3), and Moisture Sensitivity Level (1 - Unlimited) must all remain constant. Standoff length is the variable parameter that distinguishes parts within this series.

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

A: Yes, both ELM 4-3.5MM and ELM 4-145 are supplied in Bag packaging, ensuring consistent handling and storage requirements.

Q: Do these parts have different compliance or environmental ratings?

A: No, both parts share identical RoHS3 compliance status and Moisture Sensitivity Level 1 (Unlimited) ratings, indicating equivalent environmental performance and regulatory compliance.

Q: What is the significance of the 0.005" length difference?

A: The length differential accommodates varying PCB thicknesses and component placement requirements. Selection depends on the specific clearance needed between the PCB surface and the LED component in the final assembly.
