ELM 7-4MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 7-4MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a 0.157" (4.00mm) length and accommodates T1 LED packages with 2-lead configurations. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where dimensional and functional requirements permit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 7-4MM is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• LED Type: T1 (standardized LED package format)
• Lead Configuration: 2-Lead (electrical connection requirement)
• Material: Black PVC (mechanical and environmental compatibility)
• Mounting Style: Vertical (application-specific requirement)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• MSL Rating: 1 (Unlimited) (environmental handling requirement)

Secondary Consideration:

• Length tolerance: Substitute parts with lengths within the mechanical envelope of the application circuit board

The identified substitutes ELM 4-150 and ELM 5-150 share identical LED type, lead configuration, material, mounting style, RoHS compliance, and MSL rating. These parts differ in length specification (0.150" vs. 0.157"), which represents a dimensional variation that may be accommodated depending on application-specific clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

ELM 4-150 and ELM 5-150 Substitution Basis:

Both substitute parts maintain full compliance with ROHS3 regulations and carry identical MSL 1 (Unlimited) ratings, ensuring equivalent environmental handling and regulatory requirements. All three parts share the same ECCN (EAR99) and HTSUS classification, confirming consistent export and tariff treatment.

The primary distinction between the main part and substitutes is the length specification: ELM 7-4MM measures 0.157" (4.00mm), while both ELM 4-150 and ELM 5-150 measure 0.150" (3.81mm). This 0.007" (0.19mm) reduction in length represents a dimensional tolerance that must be evaluated against specific application requirements, particularly regarding circuit board clearance, component spacing, and mechanical assembly constraints.

All three parts are manufactured by Bivar Inc. and maintain active production status, ensuring supply chain continuity and consistent quality standards.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-150 or ELM 5-150 be used as direct replacements for ELM 7-4MM?

A: Both ELM 4-150 and ELM 5-150 share identical electrical and material specifications with the ELM 7-4MM. The primary difference is length: ELM 7-4MM is 0.157" (4.00mm) while the substitutes are 0.150" (3.81mm). Direct replacement is possible if the application circuit board design accommodates the 0.007" (0.19mm) shorter standoff height.

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

A: Substitution eligibility is determined by: LED type (T1), lead configuration (2-Lead), material (Black PVC), mounting style (Vertical), RoHS compliance (ROHS3), MSL rating (1 - Unlimited), and manufacturer (Bivar Inc.). Length variation is a secondary consideration dependent on application-specific mechanical requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. ELM 7-4MM, ELM 4-150, and ELM 5-150 are all ROHS3 compliant with identical MSL 1 (Unlimited) ratings.

Q: What is the inventory status of these parts?

A: ELM 7-4MM has 907 pieces in stock, ELM 4-150 has 12,323 pieces in stock, and ELM 5-150 has 1,125 pieces in stock.

Q: Do the substitute parts have different series designations?

A: Yes. ELM 7-4MM belongs to the ELM 7 series, ELM 4-150 belongs to the ELM 4 series, and ELM 5-150 belongs to the ELM 5 series. Despite different series designations, all parts meet the same functional and compliance requirements for T1 LED standoff applications.
