H-203C LED Holder: Equivalent & Substitute Parts

Part Overview

The H-203C is a T1 LED standoff holder manufactured by Bivar Inc., designed to support 3mm LEDs in right-angle mounting applications. Constructed from black nylon with a 0.380" (9.65mm) height, this component is currently in active production status and ROHS3 compliant. Substitute parts are necessary to accommodate different project requirements, including alternative material specifications (nylon versus PVC), minor height variations for PCB clearance constraints, or inventory availability across different distribution channels.

Substitute Part Grouping Explanation

Substitute parts for the H-203C LED standoff holder are determined by equivalence in the following critical parameters: LED size (T1 3mm), color (black), mounting orientation, RoHS compliance status, and moisture sensitivity level. The substitute parts maintain functional interchangeability while introducing variations in two areas:

Material Variation: The H-201C remains nylon construction identical to the main part. The ELM 2-365 and ELM 5-390 utilize PVC material instead of nylon, offering alternative mechanical and thermal characteristics while maintaining electrical compatibility and environmental compliance.

Height Variation: The H-203C and H-201C both specify 0.380" (9.65mm) height. The ELM 5-390 matches this dimension at 0.390" (9.91mm), while the ELM 2-365 offers a shorter 0.365" (9.27mm) profile. These minor dimensional differences allow for design flexibility in PCB clearance scenarios where exact height must be adjusted.

All substitute parts maintain identical LED size (T1), color (black), RoHS3 compliance, and unlimited moisture sensitivity rating, ensuring direct functional substitution within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—H-201C, ELM 5-390, and ELM 2-365—meet the same RoHS3 compliance and unlimited moisture sensitivity requirements as the H-203C. Each part is in active production status with confirmed inventory availability.

Selection between these parts depends on specific design requirements:

H-201C provides an exact dimensional and material match to the H-203C, with identical 0.380" (9.65mm) nylon construction and higher inventory availability (63,104 pieces). This part is suitable for direct replacement in existing designs with no modifications.

ELM 5-390 maintains the nylon equivalent at 0.390" (9.91mm) height using PVC construction. This part accommodates designs requiring slightly increased vertical clearance or where PVC material properties are preferable.

ELM 2-365 offers the lowest profile at 0.365" (9.27mm) with PVC construction, suitable for space-constrained applications where reduced height is required while maintaining T1 LED compatibility.

All parts carry equivalent compliance certifications and environmental ratings, permitting selection based solely on geometric and material requirements without compromise to regulatory or reliability specifications.

Frequently Asked Questions (FAQ)

Can I substitute the H-203C with the H-201C?

Yes. The H-201C is dimensionally and materially identical to the H-203C with matching 0.380" (9.65mm) length and nylon construction. Both maintain ROHS3 compliance and unlimited moisture sensitivity. This substitution requires no design modification.

What is the difference between the nylon and PVC substitute options?

The H-201C matches the H-203C in nylon material. The ELM 5-390 and ELM 2-365 substitute parts use PVC construction instead. PVC offers different mechanical and thermal characteristics compared to nylon. Material selection should align with application-specific requirements for temperature range, rigidity, and environmental exposure.

Which substitute part should I use if my PCB design has limited vertical clearance?

The ELM 2-365 provides the shortest profile at 0.365" (9.27mm), compared to the H-203C at 0.380" (9.65mm) and the ELM 5-390 at 0.390" (9.91mm). For applications requiring maximum vertical clearance reduction, the ELM 2-365 is the appropriate selection.

Are all substitute parts RoHS3 compliant?

All listed substitute parts—H-201C, ELM 5-390, and ELM 2-365—are ROHS3 compliant and carry identical environmental compliance status to the H-203C. No compliance compromise occurs with any substitution.

What is the inventory status of each substitute part?

The H-201C has the largest inventory at 63,104 pieces. The ELM 5-390 is available in 2,242 pieces. The ELM 2-365 has 16,125 pieces in stock. Inventory availability should be verified at time of procurement for project-specific lead time requirements.

Can I mix these parts within the same design or assembly?

All substitute parts maintain identical LED size (T1), color (black), mounting orientation, RoHS compliance, and moisture sensitivity. Physical interchangeability is determined by the specific dimensional requirements of your PCB and enclosure design. If your design accommodates the height variation range of 0.365" to 0.390", any of these parts can be used interchangeably within the same assembly.
