RTB14006F Equivalent & Substitute Parts

Part Overview

The RTB14006F is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, configured as a Single Pole Double Throw (SPDT) contact form with a 6VDC coil. This through-hole mounted relay is rated for 12A continuous contact current and supports switching voltages up to 400VAC. The product is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RTB14006F is based on electrical and mechanical compatibility within the following critical parameters:

Mandatory Matching Parameters:

• Coil voltage: 6VDC
• Contact form: SPDT (1 Form C)
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Seal rating: Sealed - fully

Allowable Variation Parameters:

• Contact rating current: Substitute must meet or exceed 12A requirement
• Switching voltage: Substitute must support minimum 400VAC switching capability
• Operating temperature range: Substitute must cover the required operating envelope
• Coil current and resistance: Variation acceptable within circuit design constraints
• Operate and release times: Variation acceptable based on application timing requirements

The JW1FSN-DC6V from Panasonic Electric Works meets the mandatory matching parameters but operates within a reduced switching voltage specification (250VAC, 30VDC) and lower contact current rating (10A), requiring application-level evaluation for suitability.

Engineering Selection Recommendations

The JW1FSN-DC6V from Panasonic Electric Works is an active product suitable for substitution in applications where the reduced electrical specifications are acceptable. Key considerations for selection:

Electrical Derating: The JW1FSN-DC6V contact current rating of 10A is lower than the RTB14006F specification of 12A. Applications requiring the full 12A contact current cannot use this substitute without derating analysis.

Switching Voltage Limitation: The JW1FSN-DC6V maximum switching voltage of 250VAC is significantly lower than the RTB14006F specification of 400VAC. Applications switching voltages above 250VAC require alternative substitutes.

Temperature Range: The JW1FSN-DC6V operating temperature range (-40°C to 60°C) is narrower than the RTB14006F range (-40°C to 85°C). Applications requiring operation above 60°C cannot use this substitute.

Timing Characteristics: The JW1FSN-DC6V operate time of 15ms exceeds the RTB14006F specification of 8ms. Applications with strict timing requirements must evaluate this difference.

Product Status and Compliance: The JW1FSN-DC6V is an active product with RoHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete RTB14006F.

Frequently Asked Questions (FAQ)

Q: Can the JW1FSN-DC6V directly replace the RTB14006F in all applications?

A: No. The JW1FSN-DC6V has reduced contact current rating (10A vs. 12A), lower maximum switching voltage (250VAC vs. 400VAC), and narrower operating temperature range (-40°C to 60°C vs. -40°C to 85°C). Substitution is valid only for applications operating within these reduced specifications.

Q: What is the impact of the 2A contact current difference between these relays?

A: The RTB14006F is rated for 12A continuous contact current, while the JW1FSN-DC6V is rated for 10A. Applications requiring contact currents between 10A and 12A must use the RTB14006F or identify alternative substitutes with higher current ratings.

Q: How does the 150VAC switching voltage difference affect substitution?

A: The RTB14006F supports 400VAC switching, while the JW1FSN-DC6V supports 250VAC maximum. Applications switching AC voltages above 250VAC cannot use the JW1FSN-DC6V without violating electrical specifications.

Q: Are the coil drive requirements compatible between these relays?

A: Both relays operate on 6VDC coils with identical must-operate (4.2VDC) and must-release (0.6VDC) voltages. However, the JW1FSN-DC6V draws 88mA coil current compared to 66.7mA for the RTB14006F. Drive circuits must supply sufficient current for the Panasonic relay.

Q: What is the significance of the 7ms difference in operate time?

A: The RTB14006F operates in 8ms while the JW1FSN-DC6V operates in 15ms. Applications with timing-critical switching requirements must evaluate whether the longer response time of the Panasonic relay is acceptable.

Q: Are these relays mechanically compatible for PCB mounting?

A: Both relays use through-hole mounting with PC pin termination, providing mechanical compatibility for direct PCB substitution. Physical footprint verification is required to confirm pin-to-pin compatibility.

Q: What compliance advantages does the JW1FSN-DC6V offer?

A: The JW1FSN-DC6V is RoHS3 compliant and an active product with ongoing manufacturer support. The RTB14006F is obsolete, limiting future availability and regulatory alignment for new designs.
