LED Standoff Holder 922-343 Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 922-343 is a T1 LED standoff holder manufactured from black nylon with a 0.400" (10.16mm) length. This component is designed for multi-function LED mounting applications requiring right-angle orientation and dual-lead support. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture tolerance suitable for standard storage and handling conditions. Equivalent substitute parts are identified based on matching functional parameters: T1 LED compatibility, black color, dual-lead configuration, and mechanical dimensions within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 922-343 are qualified based on the following critical parameters:

Primary Matching Criteria:

• LED Type: T1 (standardized LED form factor)
• Lead Configuration: Dual-lead (2LD) for consistent PCB mounting
• Color: Black (aesthetic and functional consistency)
• Orientation: Right-angle mounting capability
• RoHS3 Compliance: Environmental and regulatory alignment
• MSL 1 Rating: Moisture sensitivity equivalence

Secondary Tolerance Parameters:

• Length: 0.390" to 0.400" (9.91mm to 10.16mm) — mechanical fit within standard PCB clearance specifications
• Material: Nylon or PVC — both thermoplastic polymers with equivalent mechanical and thermal properties for LED standoff applications

The ELM 5-390 qualifies as a parametric equivalent based on matching all primary criteria and operating within acceptable length tolerance for right-angle LED mounting applications.

Parameter Comparison

Engineering Selection Recommendations

922-343 Selection Criteria:

• Primary application: Right-angle LED mounting with 0.400" (10.16mm) standoff height
• Nylon material preferred for specific thermal or mechanical requirements
• Established design baseline with proven field performance

ELM 5-390 Selection Criteria:

• Alternative for right-angle applications where 0.010" (0.25mm) height reduction is acceptable
• PVC material provides equivalent performance for standard environmental conditions
• Vertical orientation designation requires mechanical layout verification before substitution
• Higher inventory availability (2242 Pcs vs. 1020 Pcs) supports supply chain continuity

Compliance Equivalence: Both parts maintain identical RoHS3 compliance, MSL 1 rating, and Active product status. Selection between these parts depends on mechanical fit requirements within the target PCB assembly and specific material property needs (nylon vs. PVC).

Frequently Asked Questions (FAQ)

Q: Can ELM 5-390 directly replace 922-343 in existing designs?

A: Direct replacement requires verification of two factors: (1) PCB clearance tolerance for the 0.010" (0.25mm) length difference, and (2) mechanical compatibility with the vertical orientation designation of ELM 5-390 versus the right-angle configuration of 922-343. Orientation difference may require PCB layout modification.

Q: Are the material differences between nylon and PVC significant for LED standoff applications?

A: Both nylon and PVC are thermoplastic polymers suitable for LED standoff holders. Material selection depends on specific application requirements such as thermal cycling, chemical exposure, or mechanical stress. Both materials meet RoHS3 compliance and MSL 1 moisture sensitivity requirements.

Q: What does the 0.390" vs. 0.400" length difference mean for PCB assembly?

A: The 0.010" (0.25mm) difference falls within standard PCB component tolerance ranges. This variation is acceptable for most applications but should be verified against specific PCB clearance requirements, particularly in high-density layouts or where vertical clearance is constrained.

Q: Are both parts suitable for the same environmental conditions?

A: Yes. Both 922-343 and ELM 5-390 carry identical MSL 1 (Unlimited) ratings and RoHS3 compliance, indicating equivalent performance across standard storage, handling, and operating environments.

Q: How do I determine which part is appropriate for my application?

A: Evaluate based on: (1) required standoff height (0.400" vs. 0.390"), (2) mounting orientation (right-angle vs. vertical), (3) material preference (nylon vs. PVC), and (4) supply chain availability. Both parts are Active status with full compliance certifications.
