ELM 4-3MM

Part Overview

The ELM 4-3MM is a T1 LED Standoff manufactured by Bivar Inc., constructed from black PVC material with a length of 0.120" (3.05mm). This component is designed for vertical LED mounting applications requiring a standardized 3MM footprint with 2-lead configuration. The product maintains Active status and is ROHS3 Compliant, making it suitable for modern electronics manufacturing. Alternative models become necessary when inventory constraints occur or when dimensional variations within acceptable tolerances are required to accommodate specific assembly line requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-3MM is determined by the following critical parameters: LED type (T1), material composition (black PVC), mounting configuration (vertical, 2-lead), and RoHS compliance status. The identified substitutes maintain identical LED specifications and material properties while accommodating length variations within engineering tolerances. The ELM 4-115 and ELM 2-120 are both valid parametric equivalents based on matching core functional characteristics: T1 LED type, black PVC construction, 2-lead vertical mounting, and ROHS3 compliance. Length variations of ±0.005" (0.127mm) fall within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

All three parts (ELM 4-3MM, ELM 4-115, and ELM 2-120) carry Active product status and ROHS3 Compliant certification, qualifying them for equivalent use in component selection. The ELM 4-115 remains within the ELM 4 series with a minor length reduction of 0.005" (0.127mm), maintaining maximum dimensional consistency with the primary part. The ELM 2-120 offers identical length specification to the ELM 4-3MM while belonging to the ELM 2 series. Selection should prioritize parts with the highest current inventory availability: ELM 2-120 provides 86,435 units in stock, compared to 1,684 units for ELM 4-115 and 1,070 units for ELM 4-3MM. All parts carry MSL rating 1 (Unlimited), requiring no special moisture handling protocols.

Frequently Asked Questions (FAQ)

Q: Can ELM 4-115 be used as a direct substitute for ELM 4-3MM? A: Yes. Both parts share identical LED type (T1), material (black PVC), 2-lead vertical mounting configuration, and ROHS3 compliance. The length difference of 0.005" (0.127mm) is within standard engineering tolerances for T1 LED standoff applications.

Q: What is the primary difference between ELM 2-120 and ELM 4-3MM? A: Both parts have identical length (0.120"/3.05mm) and share all critical functional parameters: T1 LED type, black PVC material, 2-lead vertical configuration, and ROHS3 compliance. The parts differ only in series designation (ELM 2 versus ELM 4) and packaging classification.

Q: Are all three parts suitable for the same PCB assembly process? A: Yes. All three parts maintain identical Material (black PVC), LED type (T1), mounting configuration (vertical 2-lead), and moisture sensitivity rating (MSL 1). Length variations are within acceptable tolerances for standard assembly processes.

Q: Which substitute offers the best inventory position? A: ELM 2-120 maintains the largest available inventory at 86,435 units in stock, compared to 1,684 units for ELM 4-115 and 1,070 units for ELM 4-3MM.

Q: Do any of these parts require special compliance documentation? A: All three parts are ROHS3 Compliant and carry MSL rating 1 (Unlimited), requiring no special moisture or regulatory handling beyond standard industrial practices.
