Engineering Selection Recommendations

All four parts listed—TXS2SS-4.5V-X, TXS2SS-4.5V, TXS2SA-4.5V-Z, and TXS2SS-4.5V-Z—are Active product status and manufactured by Panasonic Electric Works. They are electrically and mechanically identical across all functional parameters.

Selection between these parts is determined by packaging requirements and RoHS compliance revision level:

TXS2SS-4.5V-X and TXS2SS-4.5V-Z are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
TXS2SS-4.5V is supplied in Tube packaging, suitable for manual handling and smaller quantity applications.
TXS2SA-4.5V-Z is supplied in Cut Tape (CT) & Digi-Reel® packaging, offering flexibility for mixed-volume procurement.

TXS2SA-4.5V-Z and TXS2SS-4.5V carry ROHS3 Compliant certification, while TXS2SS-4.5V-X and TXS2SS-4.5V-Z carry RoHS Compliant certification. Both compliance levels are acceptable for applications requiring RoHS adherence.

Frequently Asked Questions (FAQ)

Q: Can TXS2SS-4.5V-X be replaced with TXS2SS-4.5V?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: TXS2SS-4.5V-X uses Tape & Reel (TR) while TXS2SS-4.5V uses Tube. Selection depends on assembly process requirements and inventory management practices.

Q: What is the difference between TXS2SA-4.5V-Z and TXS2SS-4.5V-Z?

A: Both parts are electrically and mechanically identical. The difference is packaging format: TXS2SA-4.5V-Z uses Cut Tape (CT) & Digi-Reel® while TXS2SS-4.5V-Z uses Tape & Reel (TR). Both carry ROHS3 or RoHS Compliant certification.

Q: Are all substitute parts suitable for the same circuit application?

A: Yes. All four parts maintain identical electrical specifications including coil voltage (4.5 VDC), contact configuration (DPDT), current rating (1 A), switching voltage (110 VDC max), operating temperature range (-40°C to 70°C), and timing characteristics (5 ms operate and release times). They are direct functional equivalents.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Tube, or Cut Tape & Digi-Reel) affects only handling, storage, and assembly process compatibility. Electrical and mechanical performance remains identical across all packaging options.

Q: What RoHS compliance level should I select?

A: Both RoHS Compliant and ROHS3 Compliant certifications meet RoHS requirements. Selection depends on your supply chain and regulatory documentation requirements. Consult your procurement or compliance department for specific requirements.
