H-300C-2-140 LED Holder T1 Equivalent & Substitute Parts

Part Overview

The H-300C-2-140 is a T1 LED standoff holder manufactured by Bivar Inc., designed for right-angle mounting of 3mm LEDs with dual leads. This component features black nylon construction with a 0.455" (11.56mm) length and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from active product lines are necessary for ongoing design requirements and procurement continuity. Substitute parts maintain compatibility through matching LED type (T1), color (black), lead configuration (2LD), and mechanical dimensions within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the H-300C-2-140 is determined by the following critical parameters:

Primary Matching Criteria:

LED Type: T1 (all substitutes must be T1 standoffs)
Lead Configuration: 2LD (dual-lead mounting)
Color: Black
Moisture Sensitivity Level: MSL 1 (Unlimited)

Length Tolerance Consideration: The main part specifies 0.455" (11.56mm). Substitute parts are grouped into two categories based on length proximity:

Direct Length Match (0.455"): ELM 2-455 provides identical mechanical height
Proximate Length Range (0.435" to 0.470"): ELM 2-12MM, ELM 2-435, ELM 2-440, ELM 2-445, ELM 2-450, ELM 2-460, ELM 2-465, ELM 2-470 fall within acceptable mechanical tolerance for most PCB mounting applications

Material Variation: The main part uses nylon construction. Substitute parts in the ELM 2 series use PVC material. Both materials are black, non-conductive polymers suitable for LED standoff applications with MSL 1 rating.

Product Status: All substitute parts listed are Active products, ensuring ongoing availability and supply chain continuity.

Engineering Selection Recommendations

Primary Substitute (Exact Length Match): ELM 2-455 is the recommended primary substitute for H-300C-2-140. This part provides identical 0.455" (11.56mm) length, matching T1 LED type, dual-lead configuration, and black color. The part is Active status with robust inventory (1009 pcs). Material substitution from nylon to PVC does not affect functional performance for LED standoff applications, as both materials provide equivalent electrical isolation and mechanical stability at MSL 1 rating.

Secondary Substitutes (Proximate Length Range): For applications where length tolerance permits variation within ±0.015" (±0.38mm), the following parts are acceptable:

ELM 2-450 (0.450", 11.43mm)
ELM 2-445 (0.445", 11.30mm)
ELM 2-440 (0.440", 11.18mm)

All secondary substitutes maintain Active product status and MSL 1 compliance.

Alternative with Different Material: H-200C-1 is an Active nylon-based substitute maintaining the original material specification. However, its 0.380" (9.65mm) length represents a significant reduction from the 0.455" specification and is suitable only for applications with explicit length tolerance for shorter standoff height.

Compliance Basis: All substitute parts carry ECCN EAR99 classification and MSL 1 rating, matching the original part's regulatory and environmental requirements. Substitute parts in the ELM 2 series are RoHS3 compliant, providing enhanced environmental compliance compared to the obsolete H-300C-2-140.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-455 directly replace H-300C-2-140 in existing designs? A: Yes. ELM 2-455 provides identical mechanical dimensions (0.455" length), LED type (T1), lead configuration (2LD), and color (black). The material change from nylon to PVC does not affect electrical or mechanical performance for LED standoff applications. Both materials are non-conductive polymers with MSL 1 rating.

Q: What is the acceptable length tolerance for substitution? A: The primary specification is 0.455" (11.56mm). Parts within ±0.015" (±0.38mm) of this dimension—specifically ELM 2-440 through ELM 2-470—are mechanically compatible for most PCB mounting applications. Design-specific tolerance requirements must be verified against PCB layout constraints.

Q: Why are some substitute parts listed with different HTSUS codes? A: HTSUS classification differences reflect material composition variations (nylon vs. PVC) and do not affect functional equivalence. All parts maintain the same LED type, lead configuration, and electrical isolation properties.

Q: Is H-200C-1 a suitable substitute despite its shorter length? A: H-200C-1 maintains nylon material and Active product status but specifies 0.380" (9.65mm) length, representing a 0.075" (1.91mm) reduction from the original 0.455" specification. This part is suitable only for applications where PCB layout and component clearance explicitly permit shorter standoff height.

Q: What inventory considerations apply to substitute selection? A: ELM 2-455 (1009 pcs), ELM 2-465 (1112 pcs), and ELM 2-470 (1012 pcs) maintain the highest inventory levels among exact and near-exact length matches. ELM 2-460 (677 pcs) and ELM 2-445 (726 pcs) have lower inventory and may require longer lead times for bulk orders.

Q: Are all substitute parts RoHS compliant? A: All substitute parts in the ELM 2 series are RoHS3 compliant. The original H-300C-2-140 lists REACH Status as Vendor Undefined. Substitute parts provide enhanced environmental compliance documentation suitable for regulated applications.
