JTNV1AS-PA-F-DC18V Equivalent & Substitute Parts

Part Overview

The JTNV1AS-PA-F-DC18V is a general purpose relay manufactured by Panasonic Electric Works, featuring a SPST-NO (1 Form A) contact configuration with an 18VDC coil and 30A contact rating. This through-hole mounted relay is designed for industrial control applications requiring reliable switching at 277VAC maximum. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JTNV1AS-PA-F-DC18V is determined by strict equivalence across the following critical parameters:

• Coil Voltage: Must be 18VDC to ensure direct compatibility with existing circuit designs
• Contact Form: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Contact Rating: Must be rated for 30A minimum to handle the same load requirements
• Switching Voltage: Must support 277VAC maximum to operate in the same electrical environment
• Mounting Type: Must be through-hole to fit existing PCB layouts
• Termination Style: Must use PC pins for direct board connection compatibility
• Operating Temperature Range: Must span -55°C to 85°C for equivalent environmental performance
• Seal Rating: Must be fully sealed to maintain the same protection level

The T9AS1D12-18 from TE Connectivity Potter & Brumfield Relays meets all these critical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The T9AS1D12-18 is a qualified substitute for the obsolete JTNV1AS-PA-F-DC18V based on the following factors:

Product Status: The JTNV1AS-PA-F-DC18V is obsolete, while the T9AS1D12-18 is active and currently in production. This ensures long-term availability and supply chain continuity for new designs and ongoing system maintenance.

Compliance and Certifications: The T9AS1D12-18 is RoHS3 compliant, providing enhanced environmental compliance compared to the original part. Both parts carry identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications, ensuring consistent regulatory treatment.

Electrical Equivalence: All critical electrical parameters—coil voltage, contact form, current rating, switching voltage, and operating temperature range—are identical between the two parts, ensuring direct functional replacement without circuit modification.

Operational Characteristics: While minor differences exist in coil current (55.6 mA vs. 44.4 mA), coil resistance (324 Ohms vs. 405 Ohms), and switching times (15 ms operate/release vs. 20 ms operate/10 ms release), these variations remain within acceptable tolerances for general purpose relay applications and do not affect substitutability.

Frequently Asked Questions (FAQ)

Q: Can the T9AS1D12-18 be used as a direct replacement for the JTNV1AS-PA-F-DC18V without circuit modifications?

A: Yes. Both relays share identical coil voltage (18VDC), contact form (SPST-NO), current rating (30A), switching voltage (277VAC max), mounting type (through-hole), and termination style (PC pin). Direct substitution is possible without circuit redesign.

Q: What are the key differences between these two relays?

A: The primary differences are coil current (T9AS1D12-18: 55.6 mA vs. JTNV1AS-PA-F-DC18V: 44.4 mA), coil resistance (T9AS1D12-18: 324 Ohms vs. JTNV1AS-PA-F-DC18V: 405 Ohms), and switching times (T9AS1D12-18: 15 ms operate/15 ms release vs. JTNV1AS-PA-F-DC18V: 20 ms operate/10 ms release). Contact material also differs (AgCdO vs. AgSnO), though both are suitable for the specified switching voltage.

Q: Why is the JTNV1AS-PA-F-DC18V obsolete?

A: The product status reflects Panasonic Electric Works' discontinuation of this model. The T9AS1D12-18 from TE Connectivity Potter & Brumfield Relays provides equivalent functionality with active production status and improved compliance certifications.

Q: Are there any packaging differences between these relays?

A: The JTNV1AS-PA-F-DC18V is available in standard packaging, while the T9AS1D12-18 is supplied in bulk packaging. Both use identical through-hole PC pin termination suitable for PCB assembly.

Q: Does the T9AS1D12-18 meet RoHS requirements?

A: Yes. The T9AS1D12-18 is RoHS3 compliant, providing enhanced environmental compliance. The original JTNV1AS-PA-F-DC18V RoHS status is not specified in the available data.

Q: What is the moisture sensitivity level for these relays?

A: Both relays carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
