Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELM 3-510 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Matching Criteria:

• LED Type: T1 3/4 (all substitutes match this specification)
• Color: Black (all substitutes match this specification)
• Mounting Orientation: Vertical surface mount (all substitutes match this specification)
• RoHS Compliance: ROHS3 Compliant (all substitutes match this specification)

Secondary Considerations:

• Length tolerance: Substitutes range from 0.500" to 0.510" (12.70mm to 12.95mm)
• Material variation: PVC or Nylon construction
• Lead configuration: Three-lead or two-lead designs

The ELM 3-510 substitutes are grouped into two categories: same-series variants (ELM 3-500) and cross-series alternatives (ELM 1-13MM, H-278C-2). All identified substitutes maintain the T1 3/4 LED form factor and black color specification, ensuring compatibility with standard LED mounting applications.

Parameter Comparison

Engineering Selection Recommendations

ELM 3-500 (Closest Substitute)

The ELM 3-500 is the primary substitute for the ELM 3-510. Both parts share identical series designation (ELM 3), LED type (T1 3/4), material (PVC), color (Black), and lead configuration (3LD). The length difference of 0.010" (0.25mm) represents a minor dimensional variance within typical mechanical tolerances. Both parts maintain ROHS3 compliance and MSL 1 rating. This substitute is suitable for applications where the 0.010" height reduction is acceptable.

ELM 1-13MM (Cross-Series Substitute)

The ELM 1-13MM provides an alternative from the ELM 1 series with matching length (0.510"), LED type (T1 3/4), material (PVC), and color (Black). This part maintains ROHS3 compliance and MSL 1 rating. The primary distinction is series designation and base product number. This substitute is applicable when cross-series compatibility is permitted by design specifications.

H-278C-2 (Material and Configuration Variant)

The H-278C-2 differs from the ELM 3-510 in three key aspects: material composition (Nylon instead of PVC), mounting orientation (Right Angle instead of Vertical), and lead configuration (2LD instead of 3LD). Length is 0.500" (12.70mm). This part maintains ROHS3 compliance but has MSL classification as Not Applicable due to Nylon material properties. This substitute is limited to applications where right-angle mounting and two-lead configuration are functionally equivalent to the original specification.

All substitute parts are manufactured by Bivar Inc. and carry active product status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ELM 3-500 directly replace ELM 3-510 in all applications?

A: The ELM 3-500 is dimensionally shorter by 0.010" (0.25mm). Direct replacement is possible only in applications where this height reduction does not affect circuit board layout, component clearance, or optical alignment requirements. Both parts share identical LED type, material, color, and lead configuration.

Q: What is the primary difference between ELM 1-13MM and ELM 3-510?

A: The ELM 1-13MM differs in series designation (ELM 1 versus ELM 3) and base product number. Functionally, both parts match in LED type (T1 3/4), length (0.510"), material (PVC), color (Black), and compliance ratings. Series designation may indicate different manufacturing processes or design lineages but does not affect electrical or mechanical compatibility.

Q: Why does H-278C-2 have different lead configuration?

A: The H-278C-2 is specified as a two-lead (2LD) component, whereas the ELM 3-510 is three-lead (3LD). This difference reflects distinct electrical connection requirements. The H-278C-2 is suitable only for applications designed for two-lead LED standoff configurations.

Q: What does the mounting orientation difference mean for H-278C-2?

A: The ELM 3-510 features vertical surface mount orientation (SR VERT), while the H-278C-2 uses right-angle orientation (RA). These represent fundamentally different mounting geometries. Vertical mounting places the LED perpendicular to the circuit board, whereas right-angle mounting positions the LED parallel to the board surface. Selection depends on circuit board layout and optical requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. The ELM 3-510 and all identified substitutes (ELM 3-500, ELM 1-13MM, H-278C-2) carry ROHS3 Compliant certification, meeting environmental and hazardous substance restrictions.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: The ELM 3-510, ELM 3-500, and ELM 1-13MM all carry MSL 1 (Unlimited), indicating minimal moisture sensitivity and no special storage requirements. The H-278C-2 carries MSL classification as Not Applicable due to its Nylon material composition, which exhibits different moisture absorption characteristics than PVC.

Q: Which substitute has the highest inventory availability?

A: The ELM 3-500 has the highest inventory level at 32,418 pieces, followed by ELM 1-13MM at 20,735 pieces. The ELM 3-510 main part has 1,083 pieces in stock, and H-278C-2 has 1,446 pieces available.

Q: Can material substitution (PVC to Nylon) affect performance?

A: Material composition affects mechanical properties, temperature tolerance, and moisture absorption characteristics. PVC and Nylon exhibit different rigidity, thermal expansion, and environmental resistance profiles. Material substitution is valid only when the application environment and mechanical requirements are compatible with Nylon properties.
