PLED9SW LED Shunt Protector 9V Equivalent & Substitute Parts

Part Overview

The PLED9SW is a lighting protection LED shunt device manufactured by Littelfuse Inc., designed for 9V surface mount applications. This component provides transient voltage suppression for LED circuits in a DO-214AA (SMB) package. The PLED9SW is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The PLED9S is identified as a direct substitute for the PLED9SW based on the following critical parameters that determine functional equivalence:

• Voltage Rating: Both parts are rated at 9V
• Clamping Voltage: Both maintain 18V clamping specification
• Technology: Both utilize LED Shunt technology
• Circuit Count: Both feature single circuit configuration
• Package / Case: Both use DO-214AA (SMB) surface mount package
• Mounting Type: Both are surface mount devices
• Series: Both belong to the PLED® series
• RoHS Compliance: Both meet ROHS3 requirements
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary distinction is product status: PLED9S is active and available, while PLED9SW is obsolete. Packaging format differs (PLED9S supplied in Tape & Reel versus PLED9SW standard packaging), but this does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PLED9S is the appropriate substitute for the obsolete PLED9SW. Both components share identical electrical specifications (9V rating, 18V clamping voltage) and mechanical compatibility (DO-214AA SMB package, surface mount). Both meet ROHS3 compliance requirements and carry MSL 1 rating.

The PLED9S is currently in active production status with higher inventory availability (5764 units in stock versus 1080 units for the obsolete PLED9SW). The component is REACH-affected, consistent with current regulatory requirements.

For new designs or production transitions, the PLED9S should be specified. Existing designs using PLED9SW can transition to PLED9S without circuit modification, as all critical electrical and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can PLED9S directly replace PLED9SW in existing designs?

A: Yes. The PLED9S is electrically and mechanically equivalent to PLED9SW. Both components have identical voltage ratings (9V), clamping specifications (18V), package type (DO-214AA SMB), and mounting configuration (surface mount). No circuit redesign is required.

Q: What is the difference between PLED9SW and PLED9S?

A: The primary difference is product status. PLED9SW is obsolete, while PLED9S is active. PLED9S is supplied in Tape & Reel (TR) packaging format, whereas PLED9SW uses standard packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance differences between these parts?

A: No. Both PLED9SW and PLED9S are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. PLED9S additionally carries REACH-affected status, reflecting current regulatory requirements.

Q: What does the DO-214AA package specification mean?

A: DO-214AA is the industry standard package designation for SMB (Surface Mount Body) components. Both PLED9SW and PLED9S use this identical package, ensuring mechanical and footprint compatibility on PCBs.

Q: Why is PLED9SW listed as obsolete?

A: PLED9SW has been discontinued by Littelfuse Inc. The PLED9S serves as the active production equivalent. For procurement and design purposes, PLED9S should be specified for new applications and production transitions.
