H-300C-2-120 LED Holder Equivalent & Substitute Parts

Part Overview

The H-300C-2-120 is a T1 LED standoff holder manufactured by Bivar Inc., designed for right-angle mounting of 3mm LEDs with dual lead configuration. This component features black nylon construction with a 0.435" (11.05mm) standoff length and is classified as obsolete product status. Due to its obsolete designation, identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility for the H-300C-2-120 is determined by the following critical parameters: LED type (T1), color (black), moisture sensitivity level (MSL 1), and standoff length tolerance. The primary substitution criterion is mechanical compatibility, specifically the 0.435" (11.05mm) standoff length, which establishes the vertical spacing required for proper LED positioning on printed circuit boards.

Substitute parts are grouped into two categories:

Category 1: Direct Series Substitutes – Parts from the H-200C series that maintain T1 LED compatibility and black nylon construction but with different standoff lengths.

Category 2: Parametric Equivalents – Parts from the ELM 2 series that maintain T1 LED compatibility and black construction but utilize PVC material instead of nylon. These parts offer length variants that encompass or closely approximate the 0.435" (11.05mm) specification.

All substitute candidates maintain MSL 1 rating and EAR99 ECCN classification, ensuring equivalent environmental and regulatory compliance profiles.

Engineering Selection Recommendations

Primary Substitute: ELM 2-435

The ELM 2-435 provides exact dimensional equivalence to the H-300C-2-120, matching the 0.435" (11.05mm) standoff length specification. This part carries active product status, ensuring ongoing availability and supply chain continuity. The ELM 2-435 maintains T1 LED compatibility, black color, and MSL 1 rating. The material difference (PVC versus nylon) does not affect functional performance in standard LED mounting applications. RoHS3 compliance certification provides enhanced environmental and regulatory standing compared to the obsolete H-300C-2-120.

Secondary Substitutes: ELM 2-430, ELM 2-440

The ELM 2-430 (0.430" / 10.92mm) and ELM 2-440 (0.440" / 11.18mm) offer length variants within ±0.005" of the original specification. These parts are suitable for applications where minor standoff length variations are acceptable within circuit board design tolerances. Both maintain active product status and full compliance certifications.

Alternative Substitute: H-200C-1

The H-200C-1 maintains nylon material construction identical to the H-300C-2-120 but features a shorter 0.380" (9.65mm) standoff length. This part is appropriate only for designs where reduced vertical spacing is compatible with board layout requirements. Active product status and RoHS3 compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-435 be used as a direct replacement for H-300C-2-120?

A: Yes. The ELM 2-435 matches the critical dimensional specification of 0.435" (11.05mm) standoff length and maintains T1 LED compatibility, black color, and MSL 1 rating. The material change from nylon to PVC does not affect mechanical or electrical performance in standard LED mounting applications.

Q: What is the significance of the material difference between nylon and PVC substitutes?

A: Both nylon and PVC are suitable insulating materials for LED standoff holders. The material difference does not affect electrical isolation, mechanical strength, or thermal performance in typical LED mounting applications. Material selection is driven by manufacturing process and cost considerations rather than functional requirements.

Q: Are there length tolerance considerations when selecting substitute parts?

A: Yes. The H-300C-2-120 specifies 0.435" (11.05mm) standoff length. Substitute parts with lengths within ±0.010" (0.254mm) of this specification—including ELM 2-430 (10.92mm), ELM 2-435 (11.05mm), and ELM 2-440 (11.18mm)—are suitable for most applications. Designs with tight vertical spacing constraints require exact length matching.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts listed maintain MSL 1 (Unlimited) moisture sensitivity level and EAR99 ECCN classification, matching the original H-300C-2-120. The ELM 2 series parts carry RoHS3 compliance certification, providing enhanced regulatory standing for new designs and applications subject to environmental compliance requirements.

Q: Why is the H-300C-2-120 classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Bivar Inc. The ELM 2 series represents the current active product line for T1 LED standoff holders, offering equivalent functionality with modern compliance certifications and ongoing supply availability.

Q: Can H-200C-1 be used in place of H-300C-2-120?

A: H-200C-1 is functionally compatible but features a shorter 0.380" (9.65mm) standoff length compared to the 0.435" (11.05mm) specification of H-300C-2-120. This part is suitable only for applications where reduced vertical spacing is compatible with circuit board design requirements.

Q: What inventory status should be considered when selecting substitutes?

A: All listed substitute parts maintain active inventory status with quantities ranging from 669 to 1085 pieces in stock, ensuring reliable component availability for production and repair applications.
