Key Parameters

Substitute Part Grouping Explanation

The ELM 1-820 serves as a parametric equivalent to the ELM 3-830 based on the following critical parameters:

Matching Criteria:

• LED Type: T1 3/4 (identical footprint and electrical characteristics)
• Material: PVC (identical material composition)
• Color: Black (identical aesthetic and functional specification)
• Mounting Configuration: Vertical standoff (VERT designation maintained)
• RoHS Compliance: ROHS3 Compliant (equivalent regulatory status)
• Moisture Sensitivity Level: 1 (Unlimited) (identical environmental rating)
• Manufacturer: Bivar Inc. (same manufacturer, ensuring consistent quality standards)

Variable Parameter:

• Length: 0.830" (21.08mm) for ELM 3-830 versus 0.820" (20.83mm) for ELM 1-820 (0.010" difference within mechanical tolerance)

The length differential of 0.010" (0.25mm) between the main part and substitute accommodates standard design tolerance ranges for standoff applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 3-830 and ELM 1-820 maintain active product status and carry identical ROHS3 compliance certification. Selection between these parts should be based on:

1. Mechanical Fit Requirements: The 0.010" length differential must be evaluated against PCB layout and clearance specifications. The ELM 1-820 offers a shorter standoff profile at 0.820" (20.83mm).

2. Supply Availability: ELM 1-820 currently maintains higher inventory (1983 Pcs) compared to ELM 3-830 (785 Pcs), supporting supply chain continuity.

3. Regulatory Compliance: Both parts satisfy ROHS3 requirements and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental performance.

4. Manufacturer Consistency: Both parts originate from Bivar Inc., maintaining design integrity and quality standards across equivalent part families.

Frequently Asked Questions (FAQ)

Q: What determines if ELM 1-820 is a valid substitute for ELM 3-830? A: Substitution validity is established through matching LED type (T1 3/4), material (PVC), color (Black), RoHS compliance (ROHS3), and moisture sensitivity level (1). The length difference of 0.010" (0.25mm) falls within standard mechanical tolerance for standoff applications.

Q: How does the 0.010" length difference impact circuit board design? A: The length differential must be evaluated against specific PCB clearance requirements and mounting specifications. The shorter ELM 1-820 profile may provide advantages in space-constrained designs or impedance-sensitive applications requiring reduced standoff height.

Q: Are electrical characteristics identical between these parts? A: Both parts feature identical T1 3/4 LED specifications and PVC material composition, ensuring equivalent electrical performance for LED mounting applications.

Q: Can inventory levels influence part selection? A: Yes. The ELM 1-820 offers higher current inventory availability (1983 Pcs versus 785 Pcs for ELM 3-830), supporting immediate fulfillment of larger volume requirements or long-term supply planning.

Q: Do both parts meet the same compliance standards? A: Both ELM 3-830 and ELM 1-820 are ROHS3 compliant with MSL 1 (Unlimited) ratings, maintaining identical regulatory and environmental performance specifications.
