Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TXD2-L-3V-6 is determined by the following critical parameters:

• Coil voltage: 3VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Contact rating: 2 A minimum (equal or higher acceptable)
• Switching voltage: 220VDC maximum (equal or higher acceptable)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Seal rating: Sealed - Fully (exact match required)
• Operating temperature range: -40°C ~ 85°C minimum (equal or wider acceptable)

The TXD2-L-3V qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the TX-D series.

Parameter Comparison

Engineering Selection Recommendations

The TXD2-L-3V is the primary substitute for the obsolete TXD2-L-3V-6. Both components are from the same TX-D series and share identical electrical and mechanical specifications for all critical parameters. The substitute part is currently in active production status with 862 units in stock, ensuring availability for replacement and new applications.

The TXD2-L-3V demonstrates improved coil efficiency with reduced coil current (50 mA versus 76.9 mA) and increased coil resistance (60 Ohms versus 39 Ohms), while maintaining identical switching performance and operating characteristics. The substitute is RoHS Compliant, providing compliance advantage over the obsolete original part.

Packaging differs between the two parts: the original uses standard packaging while the substitute is supplied in tube packaging. This packaging difference does not affect electrical or mechanical compatibility and is suitable for both production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can TXD2-L-3V directly replace TXD2-L-3V-6 in existing designs?

A: Yes. Both parts share identical coil voltage (3VDC), contact form (DPDT), contact rating (2A), switching voltage (220VDC max), operating temperature range (-40°C to 85°C), and all mechanical specifications. The substitute is functionally equivalent for all circuit applications.

Q: What is the difference in coil current between these parts?

A: The TXD2-L-3V operates at 50 mA coil current compared to 76.9 mA for the TXD2-L-3V-6. This represents improved efficiency in the active substitute part while maintaining identical switching performance and timing characteristics.

Q: Does packaging affect compatibility?

A: No. The packaging difference (tube versus standard) does not affect electrical performance or mechanical fit. Both parts use identical PC pin termination and through-hole mounting, ensuring PCB compatibility.

Q: What is the product status difference?

A: The TXD2-L-3V-6 is obsolete and no longer manufactured. The TXD2-L-3V is in active production with current inventory availability, making it the appropriate choice for ongoing system support and new designs.

Q: Are there compliance differences?

A: The TXD2-L-3V is RoHS Compliant, providing regulatory advantage for new applications. Both parts maintain identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications and are REACH Unaffected.
