Panasonic TN2-3V DPDT General Purpose Relay Equivalent & Substitute Parts

Part Overview

The Panasonic TN2-3V is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 1 A at 3VDC coil voltage. This through-hole mounted relay features sealed construction and is designed for applications requiring dual-pole, dual-throw switching functionality. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Panasonic TN2-3V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Coil voltage: 3VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: PC pin (exact match required)
• Coil current: 46.7 mA (exact match required)
• Coil resistance: approximately 64 Ohms (tolerance range acceptable)
• Must operate voltage: 2.25 VDC (exact match required)
• Must release voltage: 0.3 VDC (exact match required)

Secondary Compatibility Criteria (Upgradeable Parameters):

• Contact rating current: 1 A minimum (higher ratings acceptable for same application)
• Switching voltage: 125VAC/110VDC minimum (higher ratings acceptable)
• Operating temperature range: -40°C ~ 70°C minimum (wider ranges acceptable)
• Seal rating: sealed construction (hermetic sealing acceptable)

The two substitute parts listed below meet all primary compatibility criteria and offer equal or superior performance in secondary parameters.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence status of the TN2-3V.

1-1462038-1 (TE Connectivity Potter & Brumfield IM/AXICOM Series): This substitute provides identical electrical performance to the TN2-3V with enhanced contact rating (2 A vs. 1 A) and switching voltage capability (250VAC/220VDC vs. 125VAC/110VDC). The hermetic seal rating exceeds the original specification. Operate and release times remain at 3 ms. Operating temperature range extends to 85°C. RoHS3 compliance is confirmed. This part is suitable for direct replacement in applications where the original 1 A rating is adequate and higher performance margins are acceptable.

V23079A1008B301 (TE Connectivity Potter & Brumfield V23079/AXICOM Series): This substitute meets all primary electrical compatibility criteria with 2 A contact rating and 250VAC/220VDC switching voltage. Operate and release times are 4 ms (1 ms longer than original). Operating temperature range extends to 85°C. RoHS3 compliance is confirmed. This part is suitable for direct replacement where the slightly extended switching time is acceptable within system timing requirements.

Both substitutes are REACH unaffected and carry EAR99 ECCN classification, matching the regulatory status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 1-1462038-1 or V23079A1008B301 be used as direct replacements for the TN2-3V?

A: Yes. Both substitute parts meet all primary electrical and mechanical compatibility criteria: identical 3VDC coil voltage, DPDT contact form, 46.7 mA coil current, through-hole PC pin termination, and identical coil resistance and operating voltage thresholds. Both are active products with current manufacturing support.

Q: What is the difference between the two substitute options?

A: The primary difference is switching time. The 1-1462038-1 maintains the original 3 ms operate and release times, while the V23079A1008B301 has 4 ms switching times. Both offer identical coil voltage, contact form, and electrical thresholds. Contact rating and switching voltage are identical between the two substitutes (2 A, 250VAC/220VDC). Selection depends on system timing requirements.

Q: Are there any temperature limitations when substituting?

A: The TN2-3V operates from -40°C to 70°C. Both substitutes extend the upper limit to 85°C, providing wider operating range. Applications operating within the original -40°C to 70°C window are fully compatible with both substitutes.

Q: What is the impact of the higher contact rating (2 A vs. 1 A)?

A: The substitute parts are rated for 2 A contact current, compared to the original 1 A rating. This represents a performance upgrade and does not create compatibility issues. Applications using the original 1 A relay will operate within the safe operating range of the 2 A substitutes.

Q: Do the substitutes have the same packaging?

A: The TN2-3V packaging is not specified in the original documentation. Both substitutes are supplied in tube packaging. PCB layout and through-hole pin spacing must be verified against original design documentation to ensure mechanical fit.

Q: Are compliance certifications equivalent?

A: Both substitutes are RoHS3 compliant and REACH unaffected, matching the regulatory status of the original part. All three parts carry EAR99 ECCN classification.
