SLM-650 Equivalent & Substitute Parts

Part Overview

The SLM-650 is an LED standoff manufactured by Bivar Inc., designed for T1 and T1 3/4 LED applications. This component features a vertical mounting configuration with a 0.650" (16.51mm) length and is constructed from black nylon material. 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 electrical and mechanical parameters align with the main part specifications, enabling direct replacement in applications where the primary component is unavailable or when inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the SLM-650 is determined by alignment across the following critical parameters:

Primary Compatibility Criteria:

• LED Type: T1 or T1 3/4 configuration
• Mounting Configuration: Vertical orientation
• Color: Black
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 or equivalent

Secondary Consideration:

• Length tolerance within application-specific mechanical constraints
• Material composition (nylon or equivalent polymeric materials)

The identified substitute parts maintain compatibility across LED type, mounting orientation, color specification, and regulatory compliance. Variations in length and material composition remain within acceptable parametric ranges for equivalent functionality.

Engineering Selection Recommendations

SLM-650 Primary Selection: The SLM-650 remains the primary component choice when available. It maintains Active product status, full RoHS3 compliance, and MSL 1 rating. Nylon construction provides established material performance for vertical LED standoff applications.

LTM-620 Substitution: The LTM-620 serves as a direct substitute when SLM-650 availability is constrained. Both parts originate from Bivar Inc., ensuring consistent manufacturing standards. The LTM-620 features crystalline polymer construction instead of nylon, with a 0.030" (0.76mm) shorter length. Active product status and identical MSL 1 rating confirm compatibility. REACH Unaffected designation provides additional regulatory clarity.

705820170 Substitution: The 705820170 from Würth Elektronik functions as an alternative substitute with nylon material matching the SLM-650. Length is 0.019" (0.49mm) longer than the main part. Active product status and ROHS3 compliance are confirmed. MSL designation is not applicable for this component. REACH Unaffected status is documented.

All three parts support T1 and T1 3/4 LED types in vertical mounting configurations with black color specification.

Frequently Asked Questions (FAQ)

Q: Can LTM-620 replace SLM-650 in all applications?

A: The LTM-620 is a parametric equivalent across LED type, mounting configuration, color, and regulatory compliance. The 0.030" length difference and crystalline polymer material composition require verification against specific mechanical clearance and thermal requirements of the target application.

Q: What is the primary difference between LTM-620 and 705820170?

A: LTM-620 uses crystalline polymer material with 0.620" length, while 705820170 uses nylon material with 0.669" length. Both maintain T1/T1 3/4 LED compatibility and vertical mounting configuration. Material selection depends on application-specific thermal and mechanical requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. SLM-650, LTM-620, and 705820170 all maintain ROHS3 Compliant status, confirming regulatory alignment for restricted substance requirements.

Q: Does moisture sensitivity level affect substitution?

A: SLM-650 and LTM-620 both carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. The 705820170 lists MSL as Not Applicable. All three parts are suitable for standard storage and handling conditions without moisture control requirements.

Q: Which substitute offers the closest dimensional match to SLM-650?

A: The 705820170 provides the closest length specification at 0.669" compared to SLM-650 at 0.650", representing a 0.019" variance. The LTM-620 at 0.620" represents a 0.030" reduction. Dimensional selection depends on available mechanical clearance in the target assembly.

Q: Can these parts be used interchangeably in PCB designs?

A: All three parts share identical LED type (T1, T1 3/4), vertical mounting configuration, and black color specification. PCB footprint compatibility depends on length tolerance acceptance and material thermal characteristics. Design verification against mechanical and thermal specifications is required before implementation.
