TXS2SL-9V Equivalent & Substitute Parts

Part Overview

The TXS2SL-9V is a general purpose relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 1 A contact rating and 9 VDC coil voltage. This surface mount relay is designed for general switching applications requiring sealed, fully protected operation across industrial temperature ranges.

The TXS2SL-9V is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TXS2SL-9V are identified based on the following critical parameters that determine functional compatibility:

Parametric Equivalents (TXS2SA-9V, TXS2SS-9V): These parts share identical electrical and mechanical specifications with the main part, including coil voltage (9 VDC), contact form (DPDT), contact rating (1 A), switching voltage (110 VDC max), mounting type (surface mount), termination style (gull wing), and operating temperature range (-40°C ~ 70°C). Both are active products from the same manufacturer series (TX-S), providing direct functional replacement.

Similar Part (V23079D1006B301): This TE Connectivity part maintains the same coil voltage (9 VDC), contact form (DPDT), mounting type (surface mount), and termination style (gull wing). However, it differs in contact rating (2 A versus 1 A), switching voltage (250 VAC/220 VDC max versus 110 VDC max), coil current (15.6 mA versus 5.6 mA), and operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C). This part is suitable for applications requiring higher current capacity and extended temperature operation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

TXS2SA-9V and TXS2SS-9V are recommended as primary substitutes for the obsolete TXS2SL-9V. Both parts are active products with identical electrical and mechanical specifications. TXS2SA-9V carries ROHS3 compliance, while TXS2SS-9V carries RoHS compliance, providing regulatory flexibility depending on application requirements. Both are available in tube packaging, suitable for production environments.

For Applications Requiring Enhanced Performance:

V23079D1006B301 is suitable for applications where higher contact current capacity (2 A), extended switching voltage capability (250 VAC/220 VDC), or wider operating temperature range (-40°C ~ 85°C) are required. This part is active and RoHS compliant. Selection of this part requires confirmation that the increased coil current (15.6 mA versus 5.6 mA) is compatible with the control circuit design.

Compliance Considerations:

All substitute parts carry current RoHS compliance certifications. The main part (TXS2SL-9V) does not specify RoHS status due to its obsolete classification. For new designs or production requiring regulatory compliance, TXS2SA-9V, TXS2SS-9V, or V23079D1006B301 are appropriate selections.

Frequently Asked Questions (FAQ)

Q: Can TXS2SA-9V or TXS2SS-9V be used as direct replacements for TXS2SL-9V?

A: Yes. Both parts are parametric equivalents with identical coil voltage (9 VDC), contact form (DPDT), contact rating (1 A), switching voltage (110 VDC max), mounting type (surface mount), termination style (gull wing), and operating temperature range (-40°C ~ 70°C). PCB layout and circuit design require no modification.

Q: What is the difference between TXS2SA-9V and TXS2SS-9V?

A: Both parts are electrically and mechanically identical. The primary difference is RoHS certification status: TXS2SA-9V carries ROHS3 compliance, while TXS2SS-9V carries RoHS compliance. Selection depends on regulatory requirements for the application.

Q: When should V23079D1006B301 be selected instead of the Panasonic equivalents?

A: V23079D1006B301 is selected when the application requires contact current capacity exceeding 1 A (rated 2 A), switching voltage exceeding 110 VDC (rated 250 VAC/220 VDC max), or operating temperatures exceeding 70°C (rated to 85°C). The increased coil current (15.6 mA) must be compatible with the control circuit.

Q: Are there packaging differences between substitute parts?

A: Yes. TXS2SL-9V is supplied in bulk packaging. TXS2SA-9V and TXS2SS-9V are supplied in tube packaging. V23079D1006B301 is supplied in tape & reel (TR) packaging. Packaging selection affects procurement, handling, and production processes.

Q: Do all substitute parts maintain the same seal rating?

A: TXS2SA-9V and TXS2SS-9V maintain the sealed, fully protected rating of the main part. V23079D1006B301 does not specify seal rating in the provided data. Applications requiring fully sealed relay operation should prioritize the Panasonic equivalents.

Q: What is the coil resistance of each part?

A: TXS2SL-9V, TXS2SA-9V, and TXS2SS-9V all have coil resistance of 1.62 kOhms. V23079D1006B301 has coil resistance of 578 Ohms, reflecting its higher coil current specification.
