ELM 1-790 LED Standoff Equivalent & Substitute Parts

Part Overview

The ELM 1-790 is a T1 3/4 LED standoff manufactured by Bivar Inc. in black PVC material with a nominal length of 0.790" (20.07mm). This component is classified as an active product with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). LED standoffs are essential mechanical support components used in electronic assemblies to position and stabilize T1 3/4 LED packages at precise heights above printed circuit boards. Substitution becomes necessary when the specified part is unavailable in required quantities or when design modifications require alternative mounting heights within the ELM 1 series specifications.

Substitute Part Grouping Explanation

The ELM 1-790 can be substituted with the ELM 1-820 based on the following allowable parameter tolerance criteria:

Critical Matching Parameters (Required for Substitution):

  • LED Package Type: T1 3/4 (identical)
  • Material: PVC (identical)
  • Color: Black (identical)
  • Series: ELM 1 (identical)
  • RoHS Status: ROHS3 Compliant (identical)
  • Moisture Sensitivity Level: 1 (Unlimited) (identical)

Variable Parameter (Allowable Difference):

  • Length: 0.790" (20.07mm) for ELM 1-790 versus 0.820" (20.83mm) for ELM 1-820

The substitution is valid because both parts share identical LED package compatibility, material composition, color specification, and regulatory compliance. The length differential of 0.030" (0.76mm) represents a geometric variation within the ELM 1 series design envelope and does not affect the mechanical or electrical interface with standard T1 3/4 LED packages.

Engineering Selection Recommendations

Both the ELM 1-790 and ELM 1-820 are active products from Bivar Inc. with identical ROHS3 compliance status and MSL 1 ratings. Selection between these parts is determined by the required standoff height for the specific application. The ELM 1-820 provides an increased mounting height of 0.030" (0.76mm) compared to the ELM 1-790. Both parts satisfy equivalent regulatory and environmental requirements and are suitable for electronic assemblies requiring lead-free and unlimited moisture exposure tolerances.

Frequently Asked Questions (FAQ)

Q: Can ELM 1-820 be used directly in place of ELM 1-790?

A: The ELM 1-820 is electrically and mechanically compatible with applications designed for the ELM 1-790. The primary difference is the increased standoff height of 0.030" (0.76mm). Design compatibility depends on the available vertical clearance in the printed circuit board assembly. Verify that the increased height does not interfere with other components or enclosure constraints.

Q: Are the RoHS compliance statuses identical between these parts?

A: Both parts are ROHS3 compliant with MSL 1 ratings, making them equivalent from a regulatory and environmental exposure standpoint.

Q: What determines compatibility between these LED standoffs?

A: Compatibility is ensured when both parts maintain the same LED package type (T1 3/4), material (PVC), color (black), series designation (ELM 1), and regulatory compliance status. The length difference is the only variable parameter between these substitutes.

Q: Are packaging quantities a factor in part selection?

A: Packaging quantities differ between these parts (ELM 1-790: 952 pcs, ELM 1-820: 1983 pcs). Availability should be evaluated based on current inventory levels and project lead time requirements, but packaging quantity does not affect functional or electrical compatibility.
