Substitute Part Grouping Explanation

Substitute parts for the ELM 1-515 are qualified based on the following critical parameters:

Primary Matching Criteria:

• LED Type: T1 3/4 (all substitutes maintain this specification)
• Color: Black (all substitutes maintain this specification)
• Mounting Configuration: Vertical standoff design
• Compliance: RoHS3 compliant status

Length Tolerance Consideration: The ELM 1-515 specifies 0.515" (13.08mm). Substitute parts are grouped into two categories based on length variation:

1. Minimal Length Variance (±0.005"): ELM 1-13MM at 0.510" (12.95mm) represents a 0.005" reduction, maintaining functional compatibility within standard mechanical tolerances.

2. Moderate Length Variance (±0.015"): ELM 3-500 and H-278C-2 both specify 0.500" (12.70mm), representing a 0.015" reduction from the original specification.

Material Variation:

• ELM 1-13MM and ELM 3-500 maintain PVC material composition
• H-278C-2 substitutes Nylon material for PVC, affecting mechanical properties and environmental performance

All substitute parts maintain T1 3/4 LED compatibility and black color specification, ensuring functional interchangeability within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

ELM 1-13MM Selection Criteria: ELM 1-13MM is the closest parametric equivalent to ELM 1-515, with a length variance of only 0.005" (0.13mm). This part maintains identical material composition (PVC), identical LED type (T1 3/4), and identical color specification (Black). Both parts carry Active product status and ROHS3 compliance. This substitute is appropriate for applications where minimal dimensional variance is acceptable and PVC material properties are required.

ELM 3-500 Selection Criteria: ELM 3-500 provides a substitute option with a 0.015" (0.38mm) length reduction. Material composition remains PVC, matching the original specification. LED type and color specifications are identical. Active product status and ROHS3 compliance are maintained. This substitute is suitable for applications where the additional length reduction does not impact mechanical fit or functional performance.

H-278C-2 Selection Criteria: H-278C-2 represents a material substitution from PVC to Nylon while maintaining T1 3/4 LED type and black color. Length specification matches ELM 3-500 at 0.500" (12.70mm). This part carries Active product status and ROHS3 compliance. Moisture Sensitivity Level is Not Applicable due to Nylon material properties. This substitute is appropriate for applications where Nylon material characteristics provide functional or environmental advantages over PVC.

All substitute parts maintain compliance certifications and active production status, supporting long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: What is the primary basis for determining substitute compatibility for the ELM 1-515?

A: Substitute compatibility is determined by matching the LED type (T1 3/4), color (Black), and vertical mounting configuration. Length variations within standard mechanical tolerances and material options (PVC or Nylon) are permitted substitution parameters.

Q: How significant is the length difference between ELM 1-515 and ELM 1-13MM?

A: The length difference is 0.005" (0.13mm), representing a 0.97% reduction from the original 0.515" specification. This variance falls within standard mechanical tolerances for LED standoff applications.

Q: Can ELM 3-500 and H-278C-2 be used interchangeably with ELM 1-515?

A: Both parts maintain T1 3/4 LED type and black color specifications. However, both introduce a 0.015" (0.38mm) length reduction compared to the original. Interchangeability depends on mechanical clearance requirements in the specific application. H-278C-2 additionally substitutes Nylon for PVC material.

Q: What is the difference between PVC and Nylon material options in these standoffs?

A: ELM 1-515, ELM 1-13MM, and ELM 3-500 use PVC material with Moisture Sensitivity Level 1 (Unlimited). H-278C-2 uses Nylon material with Moisture Sensitivity Level Not Applicable. Material selection depends on environmental exposure and mechanical property requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ELM 1-515, ELM 1-13MM, ELM 3-500, and H-278C-2 all carry ROHS3 Compliant status, supporting regulatory compliance requirements.

Q: What inventory considerations should influence substitute part selection?

A: ELM 3-500 maintains the highest inventory level at 32,418 pieces, followed by ELM 1-13MM at 20,735 pieces. ELM 1-515 has 887 pieces in stock, and H-278C-2 has 1,446 pieces. Inventory levels may influence supply chain decisions for high-volume applications.

Q: Do all substitute parts use identical packaging?

A: Yes. ELM 1-515, ELM 1-13MM, ELM 3-500, and H-278C-2 all use Bag packaging, maintaining consistent handling and storage requirements.
