ELM 2-24MM LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 2-24MM is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications. This component features a black PVC construction with a length of 0.940" (23.90mm) and is classified as an active product with ROHS3 compliance. The part is supplied in bag packaging with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowable tolerances for LED standoff applications, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 2-24MM is determined by the following critical parameters:

Primary Matching Criteria:

• LED Type: T1 (mechanical form factor)
• Material: PVC (chemical compatibility and mechanical properties)
• Color: Black (visual and thermal characteristics)
• Mounting Orientation: Vertical (PCB layout compatibility)
• RoHS Compliance: ROHS3 (regulatory requirement)
• MSL Rating: 1 or equivalent (storage and handling conditions)

Secondary Consideration:

• Length tolerance: Dimensional variation within 0.030" (0.76mm) is acceptable for vertical standoff applications where precise height is not critical to circuit function.

The ELM 5-23MM meets all primary criteria and falls within acceptable dimensional tolerance, qualifying as a parametric equivalent substitute.

Engineering Selection Recommendations

ELM 2-24MM Selection Criteria:

• Primary choice when original design specifies 0.940" (23.90mm) standoff height
• Current inventory: 998 Pcs available
• Active product status ensures continued availability and support

ELM 5-23MM Selection Criteria:

• Acceptable substitute when 0.030" (0.76mm) height reduction is compatible with circuit layout
• Higher inventory availability: 7087 Pcs in stock
• Active product status with identical compliance certifications
• Both parts maintain ROHS3 compliance and MSL 1 rating

Both parts are manufactured by Bivar Inc. and carry identical regulatory certifications (ROHS3, EAR99 ECCN classification). Selection between these parts depends solely on dimensional requirements within the specified tolerance range.

Frequently Asked Questions (FAQ)

Q: Can ELM 5-23MM directly replace ELM 2-24MM in existing designs?

A: ELM 5-23MM is a parametric equivalent with a 0.030" (0.79mm) shorter length. Direct replacement is possible if the circuit layout accommodates this dimensional difference. Both parts share identical LED type (T1), material (PVC), color (Black), and compliance ratings.

Q: What is the dimensional tolerance between these parts?

A: ELM 2-24MM measures 0.940" (23.90mm) and ELM 5-23MM measures 0.910" (23.11mm), representing a 0.030" (0.79mm) difference. This variation is within acceptable limits for vertical LED standoff applications where precise height is not a critical design parameter.

Q: Are both parts RoHS compliant?

A: Yes. Both ELM 2-24MM and ELM 5-23MM are ROHS3 compliant and carry identical environmental ratings (MSL 1 - Unlimited).

Q: What is the difference in packaging between these parts?

A: Both parts are supplied in bag packaging. No packaging format differences exist between the main part and substitute.

Q: Which part should be selected for new designs?

A: Selection depends on required standoff height. If 0.940" (23.90mm) is specified, use ELM 2-24MM. If 0.910" (23.11mm) is acceptable, ELM 5-23MM offers higher inventory availability (7087 Pcs vs. 998 Pcs).

Q: Are there any material or chemical compatibility differences?

A: No. Both parts use identical PVC material and black color specification, ensuring equivalent chemical compatibility and thermal characteristics in PCB applications.
