Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-205 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Bivar Inc. (same manufacturer ensures design consistency)
• LED Type: T1 (physical package standard)
• Material: PVC (chemical and thermal properties)
• Color: Black (aesthetic and functional consistency)
• Lead Count: 2LD (electrical connectivity requirement)
• Mounting Style: Vertical (application-specific orientation)
• RoHS Status: ROHS3 Compliant (regulatory requirement)
• MSL Rating: 1 (Unlimited) (environmental tolerance)

Allowable Variation:

• Length tolerance: Mechanical dimension variance within functional application limits

The ELM 2-5MM qualifies as a parametric equivalent based on matching all primary compatibility criteria, with a minor length variation of 0.005" (0.13mm) from the main part specification.

Engineering Selection Recommendations

ELM 4-205 Primary Selection: Use the ELM 4-205 when the specified 0.205" (5.21mm) length is a design requirement. This part is Active status with full RoHS3 compliance and unlimited MSL rating, suitable for standard manufacturing environments.

ELM 2-5MM Substitute Selection: The ELM 2-5MM serves as a functional equivalent when the 0.005" (0.13mm) length reduction is acceptable within application tolerances. This substitute maintains identical electrical and material specifications, RoHS3 compliance, and Active product status. Higher inventory availability (2755 Pcs vs. 842 Pcs) may support supply chain optimization.

Both parts satisfy identical regulatory and environmental requirements. Selection between these parts depends solely on mechanical length tolerance acceptance in the target application.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-5MM replace ELM 4-205 in all applications?

A: ELM 2-5MM qualifies as a substitute where the 0.005" (0.13mm) shorter length does not violate mechanical clearance or assembly requirements. All electrical, material, and compliance specifications are identical.

Q: What is the significance of the length difference between these parts?

A: The ELM 4-205 measures 0.205" (5.21mm) while ELM 2-5MM measures 0.200" (5.08mm). This 0.005" (0.13mm) variance is the only dimensional difference. Substitution feasibility depends on application-specific mechanical tolerances and clearance requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ELM 4-205 and ELM 2-5MM carry RoHS3 Compliant certification, meeting current regulatory requirements for restricted substances.

Q: What does MSL 1 (Unlimited) mean for these components?

A: MSL 1 rating indicates these components have unlimited moisture sensitivity tolerance and require no special moisture control during storage, handling, or assembly.

Q: Do these parts use identical packaging?

A: Both parts are supplied in Bag packaging format, suitable for standard component handling and storage procedures.

Q: Can I mix ELM 4-205 and ELM 2-5MM in the same assembly?

A: Mixing is permissible only if the application design accommodates the 0.005" (0.13mm) length variance without affecting form factor, clearance, or functional performance.

Q: What is the lead count specification for these parts?

A: Both parts feature 2LD (2 leads), providing standard electrical connectivity for T1 LED packages in vertical mounting configurations.
