TXD2SS-L-3V-4 Equivalent & Substitute Parts

Part Overview

The TXD2SS-L-3V-4 is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with 10 mA contact rating and 3VDC coil voltage. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The relay operates with a latching, single coil design and is housed in a surface mount gull wing package with full sealing.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TXD2SS-L-3V-4 is determined by strict alignment of the following critical parameters:

• Coil voltage: 3VDC (exact match required)
• Contact configuration: DPDT (2 Form C) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Termination style: Gull Wing (exact match required)
• Coil type: Latching, Single Coil (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• Must operate voltage: 2.25 VDC (exact match required)
• Operate and release time: 4 ms (exact match required)

The identified substitute parts meet these core criteria. Variations in contact rating current, switching voltage, coil current, and coil resistance are permissible when the application requirements allow for higher current handling or different electrical characteristics, provided all mandatory parameters align.

Parameter Comparison

Engineering Selection Recommendations

TXD2SS-L-3V is the primary substitute for the obsolete TXD2SS-L-3V-4. Both components are manufactured by Panasonic Electric Works within the TX-D series, share identical coil voltage, contact configuration, and timing specifications. The TXD2SS-L-3V maintains active product status and is RoHS compliant, making it suitable for new designs and legacy system replacements. This part is available in Tube packaging with 886 pieces in stock.

V23079J1108B301 manufactured by TE Connectivity Potter & Brumfield Relays is an alternative substitute meeting all mandatory electrical and mechanical parameters. This component is RoHS compliant and available in Tape & Reel packaging with 997 pieces in stock. The V23079J1108B301 offers higher contact current rating (2 A versus 10 mA) and lower coil current (23.3 mA versus 76.9 mA), providing enhanced performance characteristics for applications requiring greater current handling capacity.

Both substitute parts are active products with full availability, eliminating obsolescence risk associated with the original TXD2SS-L-3V-4.

Frequently Asked Questions (FAQ)

Q: Can TXD2SS-L-3V directly replace TXD2SS-L-3V-4 in existing designs?

A: Yes. Both parts share identical coil voltage (3VDC), contact configuration (DPDT), mounting type (Surface Mount), termination style (Gull Wing), coil type (Latching, Single Coil), operating temperature range (-40°C ~ 85°C), must operate voltage (2.25 VDC), and timing specifications (4 ms operate and release time). The primary difference is contact rating current: TXD2SS-L-3V is rated for 2 A compared to 10 mA for TXD2SS-L-3V-4. This higher rating is compatible with applications designed for the original part.

Q: What are the key differences between TXD2SS-L-3V and V23079J1108B301?

A: Both parts meet all mandatory substitution criteria. Key differences include manufacturer (Panasonic Electric Works versus TE Connectivity), coil current (50 mA versus 23.3 mA), coil resistance (60 Ohms versus 128 Ohms), contact material composition (Silver/Gold versus Silver Nickel/Gold), and packaging format (Tube versus Tape & Reel). The V23079J1108B301 supports higher switching voltage (250VAC, 220VDC maximum versus 220VDC maximum).

Q: Are both substitute parts RoHS compliant?

A: Yes. TXD2SS-L-3V and V23079J1108B301 are both RoHS compliant, meeting environmental and regulatory requirements for new product designs and manufacturing.

Q: What packaging options are available for these substitutes?

A: TXD2SS-L-3V is supplied in Tube packaging. V23079J1108B301 is supplied in Tape & Reel (TR) packaging. Selection depends on assembly process requirements and volume considerations.

Q: Why is the contact rating current higher in the substitute parts?

A: The TXD2SS-L-3V and V23079J1108B301 are rated for 2 A contact current, compared to 10 mA for the original TXD2SS-L-3V-4. This higher rating does not prevent substitution; applications designed for 10 mA operation remain fully compatible. The higher rating provides additional design margin and flexibility for future applications.
