RL4-560 LED Standoff Equivalent & Substitute Parts

Part Overview

The RL4-560 is an all rectangular LED standoff manufactured by Bivar Inc., featuring a white nylon construction with a 0.560" (14.22mm) vertical mounting height. This component is designed for applications requiring precise LED positioning and alignment in electronic assemblies. The part maintains Active product status and is ROHS3 compliant, making it suitable for current production environments. Substitute parts may be required due to inventory constraints, design modifications requiring different standoff heights, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RL4-560 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Bivar Inc.
• LED Type: All Rectangular LEDs
• Color: White
• Material: Nylon
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter:

• Length (Height): Tolerance-dependent on application requirements

The RL3-540 qualifies as a parametric equivalent because it maintains identical specifications across all mandatory parameters. The primary difference is the standoff height of 0.540" (13.72mm) versus the 0.560" (14.22mm) of the main part. This 0.020" (0.50mm) height differential represents a mechanical variation that may be acceptable depending on circuit board layout and component clearance requirements.

Engineering Selection Recommendations

RL4-560 Selection Criteria:

• Primary choice when exact 0.560" (14.22mm) standoff height is required by design specification
• Preferred for applications with tight vertical clearance requirements
• Suitable for designs where LED positioning relative to PCB surface is critical

RL3-540 Selection Criteria:

• Acceptable substitute when design allows 0.020" (0.50mm) height reduction
• Appropriate for applications where vertical clearance tolerance accommodates the shorter standoff
• Valid alternative when RL4-560 inventory is constrained

Both parts maintain identical compliance certifications (ROHS3), material composition (white nylon), and moisture sensitivity ratings (MSL 1). Both are manufactured by Bivar Inc. and support all rectangular LED configurations. Selection between these parts depends solely on mechanical height requirements within the assembly design.

Frequently Asked Questions (FAQ)

Q: Can RL3-540 be used as a direct replacement for RL4-560?

A: The RL3-540 is a parametric equivalent with identical electrical and material properties. However, the 0.020" (0.50mm) height difference must be evaluated against your specific design requirements. If your circuit board layout and component clearance specifications accommodate this height variation, substitution is valid.

Q: What are the key differences between RL4-560 and RL3-540?

A: The primary difference is standoff height: RL4-560 measures 0.560" (14.22mm) while RL3-540 measures 0.540" (13.72mm). Both parts are manufactured from white nylon by Bivar Inc., support all rectangular LED types, and maintain identical RoHS3 compliance and MSL ratings.

Q: Are both parts available in the same packaging format?

A: Yes. Both RL4-560 and RL3-540 are supplied in Bag packaging, ensuring consistent handling and storage procedures.

Q: Do these parts have different compliance or certification status?

A: No. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. They share identical ECCN (EAR99) and HTSUS (3926.90.9985) classifications.

Q: Which part should I select if height is not a constraint?

A: Selection should be based on current inventory availability and supply chain requirements. Both parts are Active status products from Bivar Inc. with equivalent compliance profiles. RL4-560 currently has 1067 units in stock, while RL3-540 has 830 units available.

Q: Can I use these parts interchangeably in the same assembly?

A: Interchangeability depends on your design tolerance for the 0.020" height difference. If your PCB layout, component spacing, and clearance requirements allow for this variation, the parts are interchangeable. If exact height specification is critical, use only the specified part number.
