JTN1S-PA-F-DC5V Equivalent & Substitute Parts

Part Overview

The JTN1S-PA-F-DC5V is a general purpose relay manufactured by Panasonic Electric Works, featuring a Single Pole Double Throw (SPDT) contact configuration with a 5VDC coil. This through-hole mounted relay is rated for 20A switching capacity at up to 277VAC and is designed for non-latching applications. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued component availability is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JTN1S-PA-F-DC5V is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 5VDC (exact match required)
• Contact Configuration: SPDT (1 Form C) (exact match required)
• Current Rating: 20A (exact match required)
• Mounting Technology: Through Hole with PC Pin termination (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)
• Seal Rating: Sealed - Fully (exact match required)

The T9AS5D12-5 manufactured by TE Connectivity Potter & Brumfield Relays meets all critical substitution criteria. Both relays share identical coil voltage, contact form, current rating, mounting type, termination style, temperature range, and seal rating. Variations in coil current (160 mA vs. 200 mA), operate/release timing, and contact material do not preclude functional substitution when the application circuit is designed to accommodate the substitute part's electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The T9AS5D12-5 is a direct functional substitute for the obsolete JTN1S-PA-F-DC5V. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain identical compliance certifications (RoHS and EAR99 classification) and share equivalent moisture sensitivity ratings.

The T9AS5D12-5 exhibits slightly higher coil current (200 mA vs. 160 mA) and lower coil resistance (25 Ohms vs. 31 Ohms), requiring verification that the application's power supply and drive circuitry can accommodate the increased coil current draw. The substitute part demonstrates faster operate time (15 ms vs. 20 ms) and equivalent release time performance. Contact material differs (Silver Cadmium Oxide vs. Silver Tin Oxide), which does not affect substitution suitability for standard switching applications.

Frequently Asked Questions (FAQ)

Q: Can the T9AS5D12-5 be used as a direct replacement for the JTN1S-PA-F-DC5V without circuit modification?

A: The T9AS5D12-5 meets all critical electrical and mechanical parameters for substitution. However, the increased coil current (200 mA vs. 160 mA) must be accommodated by the drive circuit. Verify that the control circuit can supply the additional 40 mA without exceeding component ratings or causing voltage regulation issues.

Q: What is the impact of the different coil resistance values?

A: The T9AS5D12-5 has lower coil resistance (25 Ohms vs. 31 Ohms). At 5VDC, this results in higher coil current draw. The application circuit must be designed to supply this current. The lower resistance also results in faster electromagnetic response, which may be beneficial in time-sensitive switching applications.

Q: Are there any compatibility concerns with the different contact materials?

A: Both Silver Tin Oxide (AgSnO) and Silver Cadmium Oxide (AgCdO) contact materials are suitable for general purpose switching applications. Contact material selection does not affect substitution compatibility for standard DC and AC switching loads within the specified voltage and current ratings.

Q: Does the faster operate time of the T9AS5D12-5 affect system performance?

A: The T9AS5D12-5 operates 5 ms faster (15 ms vs. 20 ms). This improvement does not create compatibility issues and may enhance system responsiveness. Applications with timing-critical requirements should verify that the faster response time aligns with system specifications.

Q: Are both parts suitable for the same PCB footprint?

A: Both relays feature identical through-hole PC pin termination and are designed for standard relay socket mounting. Physical dimensions and pin spacing must be verified against the original PCB design to confirm mechanical compatibility.

Q: What is the significance of the different RoHS compliance levels?

A: The JTN1S-PA-F-DC5V is RoHS Compliant, while the T9AS5D12-5 is ROHS3 Compliant. ROHS3 represents a more recent compliance standard with additional restricted substance requirements. The T9AS5D12-5 meets or exceeds the original part's environmental compliance requirements.
