Substitute Part Grouping Explanation

Substitute parts for the H-300C-1-140 are grouped into two primary categories based on allowed electrical and mechanical parameters:

Similar Manufacturer Parts (Same Series, Active Status): The H-200C represents a directly compatible substitute within the Bivar H-series line. This part shares identical LED type (T1), material (Nylon), color (Black), lead configuration (2LD), and MSL rating (1). The primary difference is length: 0.380" (9.65mm) versus the original 0.455" (11.56mm). This variant is suitable for applications requiring reduced standoff height while maintaining mechanical and electrical compatibility.

Parametric Equivalents (ELM Series, Material Variation): The ELM 2-series parts (ELM 2-12MM, ELM 2-435, ELM 2-440, ELM 2-445, ELM 2-450, ELM 2-455, ELM 2-460, ELM 2-465, ELM 2-470) serve as parametric equivalents with the following key parameters:

LED Type: T1 (consistent)
Color: Black (consistent)
Lead Configuration: 2LD (consistent)
MSL Rating: 1 (consistent)
Material: PVC (differs from original Nylon)
Length: Range from 0.435" (11.05mm) to 0.470" (11.94mm)

The ELM 2-455 provides the closest dimensional match at 0.455" (11.56mm), while the full range allows selection based on specific PCB height constraints.

Engineering Selection Recommendations

Primary Substitute (Dimensional Match): The ELM 2-455 provides an exact length match at 0.455" (11.56mm) with active product status and ROHS3 compliance. Material substitution from Nylon to PVC does not affect functional performance in standard LED mounting applications within the specified MSL rating.

Secondary Substitute (Series Continuity): The H-200C maintains material continuity with the original design (Nylon) and active status. Selection of H-200C is appropriate where the reduced 0.380" (9.65mm) height accommodates PCB layout constraints while preserving Nylon construction and ROHS3 compliance.

Extended Alternatives (Close Dimensional Range): The ELM 2-series parts with lengths 0.450" (11.43mm) through 0.465" (11.81mm) provide dimensional tolerance for applications permitting height variation within ±0.015" of the original specification. All ELM 2-series alternatives carry active status and ROHS3 compliance certifications.

Selection among substitute parts should be based on PCB assembly requirements regarding standoff height, material properties, and assembly process constraints. All identified substitutes share critical electrical and mechanical parameters with the original H-300C-1-140.

Frequently Asked Questions (FAQ)

Q: Can the H-200C replace the H-300C-1-140 in all applications? A: The H-200C is electrically equivalent but features reduced length (0.380" versus 0.455"). It is suitable for applications where PCB-to-component clearance permits the reduced height. Verify PCB design clearances before substitution.

Q: What is the difference between Nylon and PVC material options? A: The original H-300C-1-140 uses Nylon while ELM 2-series alternatives use PVC. Both materials meet MSL 1 requirements and provide suitable dielectric properties for T1 LED mounting. Material selection should be based on specific application environmental and thermal requirements documented in the original design specification.

Q: Which ELM 2-series part is the best direct replacement? A: The ELM 2-455 provides exact dimensional correspondence at 0.455" (11.56mm) and is recommended for direct substitution where the PVC material is acceptable. All ELM 2-series parts maintain T1 LED compatibility and dual-lead configuration.

Q: Are all substitutes ROHS3 compliant? A: The H-200C and all ELM 2-series parts carry ROHS3 compliance. The original H-300C-1-140 has undefined vendor RoHS status due to obsolescence. Substitution with ROHS3-compliant alternatives is recommended for current production applications.

Q: What is the inventory status of substitute parts? A: All substitute parts carry active status with current inventory ranging from 677 to 1112 units. The H-200C has 849 units in stock. Confirm current availability through supplier documentation for production scheduling.

Q: Do the substitute parts maintain the same footprint on the PCB? A: All parts accommodate 3mm LED packages with dual-lead configuration in right-angle mounting. PCB pad and lead hole positioning remain compatible. Verify PCB artwork specifications for any lead diameter or hole tolerance variations in the original design.
