ELM 4-370 Equivalent & Substitute Parts

Part Overview

The ELM 4-370 is a T1 LED standoff manufactured by Bivar Inc., designed for vertical mounting applications with a 0.370" (9.40mm) length. This component features a black PVC construction and accommodates 2-lead configurations. The part maintains Active product status and is RoHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity tolerance.

Substitute parts are identified when equivalent functional performance can be achieved through alternative designs that maintain compatibility with the same LED form factor (T1), mounting orientation (vertical), lead configuration (2-lead), and material properties suitable for the application environment.

Substitute Part Grouping Explanation

Substitution logic for the ELM 4-370 is based on the following criteria:

Primary Compatibility Factors:

• LED form factor must be T1
• Mounting orientation must be vertical (SR VERT)
• Lead configuration must be 2-lead (2LD)
• Color must be black
• RoHS3 compliance required
• MSL 1 rating required

Secondary Compatibility Factors:

• Material composition (PVC or Nylon acceptable)
• Length tolerance within 0.365" to 0.380" range

The identified substitutes (ELM 2-365 and H-201C) satisfy all primary compatibility factors. Variations in material composition and length within the specified tolerance range do not affect functional equivalence for standard LED mounting applications.

Parameter Comparison

Engineering Selection Recommendations

ELM 4-370 (Primary Part): Use when exact 0.370" length specification is required. Active product status with established supply chain. PVC material suitable for standard environmental conditions.

ELM 2-365 (Vertical Mounting Substitute): Functionally equivalent for vertical mounting applications. Length variation of 0.005" (0.13mm) is within standard mechanical tolerance for LED standoff applications. PVC material matches primary part. Higher inventory availability (16125 units) supports production continuity. Suitable for direct substitution in vertical orientation designs.

H-201C (Right Angle Mounting Substitute): Functionally equivalent only for applications requiring right-angle mounting orientation. Nylon material provides alternative thermal and mechanical properties compared to PVC. Significantly higher inventory availability (63104 units). Length variation of 0.010" (0.25mm) remains within acceptable tolerance. Not suitable for vertical mounting applications requiring the ELM 4-370 orientation.

All three parts maintain Active product status, ROHS3 compliance, and MSL 1 rating, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-365 replace ELM 4-370 in all applications?

A: ELM 2-365 is functionally equivalent for vertical mounting applications. The 0.005" length difference falls within standard mechanical tolerance for LED standoff assemblies. Both parts share identical LED form factor (T1), lead configuration (2-lead), color (black), material (PVC), and compliance ratings. Substitution is valid for vertical orientation designs.

Q: What is the key difference between ELM 2-365 and H-201C?

A: The primary difference is mounting orientation. ELM 2-365 is designed for vertical mounting (SR VERT), while H-201C is designed for right-angle mounting (RA). Material composition also differs: ELM 2-365 uses PVC, while H-201C uses Nylon. Both maintain T1 LED compatibility and 2-lead configuration. Selection depends on PCB layout requirements.

Q: Can H-201C be used in place of ELM 4-370?

A: H-201C is not suitable as a direct substitute for ELM 4-370 due to different mounting orientation. ELM 4-370 is vertical mounting; H-201C is right-angle mounting. These orientations are not interchangeable in PCB designs. However, H-201C is functionally equivalent for applications specifically requiring right-angle LED mounting with T1 form factor and 2-lead configuration.

Q: Are there material compatibility considerations between PVC and Nylon options?

A: Both PVC (ELM 4-370, ELM 2-365) and Nylon (H-201C) materials are RoHS3 compliant with MSL 1 rating. Material selection depends on application environment. PVC is suitable for standard conditions; Nylon provides alternative thermal and mechanical properties. Both materials are acceptable for typical LED standoff applications without additional environmental specifications.

Q: What packaging format is used for these parts?

A: All three parts (ELM 4-370, ELM 2-365, H-201C) are supplied in Bag packaging format, suitable for standard component handling and assembly processes.

Q: Are there regulatory or compliance differences between the substitute parts?

A: No. All three parts maintain identical compliance status: ROHS3 compliant, MSL 1 (Unlimited), and EAR99 ECCN classification. Regulatory requirements do not differentiate between these substitutes.
