Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELM 4-705 is determined by the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 (3mm package)
• Lead Configuration: 2-Lead (2LD)
• Mounting Style: Vertical
• Material: Black PVC
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ELM 2-17MM qualifies as a parametric equivalent based on matching LED type (T1), lead configuration (2LD), mounting orientation (vertical), material composition (black PVC), and compliance certifications (ROHS3). Length variation between 0.705" (17.91mm) and 0.670" (17.02mm) falls within the mechanical tolerance range for this product category, permitting functional substitution in applications where standoff height is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

Both the ELM 4-705 and ELM 2-17MM maintain Active product status with ROHS3 compliance and MSL 1 rating, confirming suitability for current production and long-term storage without moisture control requirements.

Selection between these parts is determined by mechanical height requirements. The ELM 4-705 provides 0.705" (17.91mm) standoff height, while the ELM 2-17MM provides 0.670" (17.02mm) standoff height. The 0.035" (0.89mm) difference must be evaluated against specific PCB layout and component clearance specifications.

Both parts are manufactured by Bivar Inc. using identical material composition (black PVC), LED accommodation (T1, 3mm), and lead configuration (2-lead vertical mount), ensuring electrical and mechanical compatibility within the tolerance parameters of this product category.

Frequently Asked Questions (FAQ)

Q: Can ELM 2-17MM directly replace ELM 4-705 in all applications?

A: Direct replacement is valid when standoff height variation of 0.035" (0.89mm) does not affect circuit performance or mechanical clearance. Both parts share identical LED type (T1), lead configuration (2LD), material (black PVC), and compliance certifications (ROHS3). Height-critical applications require design verification.

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

A: The ELM 4-705 measures 0.705" (17.91mm) while the ELM 2-17MM measures 0.670" (17.02mm). This 0.035" (0.89mm) difference affects vertical clearance between the LED and PCB surface. Applications with restricted vertical space or specific optical alignment requirements must account for this variation.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELM 4-705 and ELM 2-17MM are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, permitting use in regulated manufacturing environments without special storage or handling protocols.

Q: What packaging format is used for these parts?

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

Q: Do these parts share the same manufacturer?

A: Yes. Both the ELM 4-705 and ELM 2-17MM are manufactured by Bivar Inc., ensuring consistent material quality and construction standards across the product line.
