Substitute Part Grouping Explanation

Substitute parts for the TQ2SA-5V-Z are classified into two categories based on parametric alignment:

Parametric Equivalents (TQ2SL-5V-Z, TQ2SS-5V-Z): These parts share identical electrical specifications with the main part, including coil voltage, contact form, contact rating, coil current, switching voltage, operating temperature range, and coil resistance. The primary difference is packaging format: TQ2SL-5V-Z and TQ2SS-5V-Z are supplied in Tape & Reel (TR) format, whereas TQ2SA-5V-Z is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging types are suitable for automated assembly processes and represent direct functional substitutes.

Similar Part (IM03GR): The IM03GR, manufactured by TE Connectivity Potter & Brumfield Relays, meets the core electrical requirements: 5VDC coil voltage, DPDT contact form, 2A contact rating, and identical coil resistance. Key differences include higher switching voltage rating (250VAC vs. 125VAC), faster switching times (3 ms vs. 4 ms), hermetically sealed construction, and different contact material composition (Palladium/Ruthenium/Gold vs. Silver Nickel/Gold). The IM03GR is classified as a similar part due to these performance enhancements and design differences, suitable for applications requiring superior environmental protection or faster response characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Parametric Equivalents): TQ2SL-5V-Z and TQ2SS-5V-Z are suitable direct replacements for TQ2SA-5V-Z in applications where packaging format flexibility is acceptable. All three parts are active products with ROHS3 compliance and REACH unaffected status. Selection between these parametric equivalents depends on supply chain availability and assembly process requirements (Cut Tape vs. Tape & Reel format).

For Enhanced Performance Applications: IM03GR is suitable for applications requiring higher switching voltage capability (250VAC vs. 125VAC), faster response times (3 ms vs. 4 ms), or hermetically sealed construction for enhanced environmental protection. The IM03GR maintains identical coil voltage, contact form, contact rating, and coil resistance specifications, ensuring functional compatibility while providing performance enhancements. This part is active and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can TQ2SL-5V-Z or TQ2SS-5V-Z be used as direct replacements for TQ2SA-5V-Z?

A: Yes. TQ2SL-5V-Z and TQ2SS-5V-Z are parametric equivalents with identical electrical specifications. The only difference is packaging format: TQ2SA-5V-Z uses Cut Tape (CT) & Digi-Reel® format, while TQ2SL-5V-Z and TQ2SS-5V-Z use Tape & Reel (TR) format. Both packaging types are compatible with automated assembly processes.

Q: What are the key differences between the Panasonic TQ-SMD series relays and the TE Connectivity IM03GR?

A: The IM03GR offers higher switching voltage rating (250VAC vs. 125VAC), faster switching times (3 ms vs. 4 ms), and hermetically sealed construction. Electrical specifications including coil voltage, contact form, contact rating, and coil resistance are identical. The IM03GR is suitable for applications requiring enhanced environmental protection or faster response characteristics.

Q: Are all substitute parts RoHS compliant?

A: Yes. TQ2SA-5V-Z, TQ2SS-5V-Z, and IM03GR are ROHS3 compliant. TQ2SL-5V-Z is RoHS compliant. All parts are REACH unaffected.

Q: What is the significance of coil resistance matching at 178 Ohms?

A: Coil resistance determines the current draw and thermal characteristics of the relay. All listed parts maintain 178 Ohms coil resistance, ensuring equivalent power consumption and thermal behavior in the application circuit.

Q: Can IM03GR be used in applications designed for TQ2SA-5V-Z?

A: IM03GR is suitable for applications where the higher switching voltage rating and faster response times do not conflict with circuit design requirements. The identical coil voltage, contact form, contact rating, and coil resistance ensure electrical compatibility. Circuit validation is necessary to confirm suitability for specific application requirements.
