RTD14005 General Purpose Relay SPDT 16A 5V Equivalent & Substitute Parts

Part Overview

The RTD14005 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, featuring a single pole double throw (SPDT) contact configuration with a 5VDC coil. This through-hole mounted relay is rated for 16A switching current at up to 400VAC maximum switching voltage. The part is currently active in production with 3200 units in stock.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support component standardization across manufacturing environments. Substitutes maintain functional compatibility through matching electrical specifications and mechanical form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RTD14005 is determined by the following critical parameters:

Primary Matching Criteria:

• Coil voltage: 5VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 16A minimum
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Must operate voltage: 3.5 VDC
• Must release voltage: 0.5 VDC

Secondary Compatibility Factors:

• Switching voltage rating equal to or exceeding 400VAC
• Operating temperature range encompassing -40°C to 85°C
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

All four substitute parts (ALZ11B05, ALZ11B05W, ALZ12F05, ALZ12F05W) manufactured by Panasonic Electric Works meet these primary criteria. Variations exist in seal rating, coil insulation class, operating temperature upper limit, contact material, and packaging format, which are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active production components with ROHS3 compliance and unlimited moisture sensitivity rating, meeting the regulatory and environmental requirements of the RTD14005.

ALZ11B05 and ALZ11B05W maintain the same operating temperature range as the RTD14005 (-40°C to 85°C). These parts feature Class B coil insulation and sealed flux protection. ALZ11B05W is supplied in bulk packaging, while ALZ11B05 is supplied in tube packaging.

ALZ12F05 and ALZ12F05W extend the operating temperature range to -40°C to 105°C and feature Class F coil insulation with full sealing. These parts provide enhanced thermal performance for applications requiring higher temperature operation. ALZ12F05W is supplied in bulk packaging, while ALZ12F05 is supplied in tube packaging.

All substitute parts carry cURus and VDE approval agency certifications. The switching voltage rating of 440VAC on all Panasonic substitutes exceeds the RTD14005 specification of 400VAC, providing additional margin in high-voltage switching applications.

Frequently Asked Questions (FAQ)

Q: Can ALZ11B05 directly replace RTD14005 in existing designs?

A: Yes. ALZ11B05 matches all primary electrical specifications including 5VDC coil voltage, SPDT contact form, 16A current rating, 3.5VDC must-operate voltage, and 0.5VDC must-release voltage. The operating temperature range is identical (-40°C to 85°C). Coil resistance differs by 1 ohm (63 ohms versus 62 ohms), which is within acceptable tolerance for general purpose relay applications.

Q: What is the difference between ALZ11B05 and ALZ12F05?

A: Both parts are functionally equivalent for the RTD14005 application. ALZ12F05 extends the maximum operating temperature to 105°C and features Class F coil insulation with full sealing, compared to ALZ11B05 which operates to 85°C with Class B coil insulation and flux protection sealing. Select ALZ12F05 for applications requiring higher temperature operation.

Q: Does packaging format affect electrical performance?

A: No. The "W" suffix indicates bulk packaging (ALZ11B05W, ALZ12F05W) versus tube packaging (ALZ11B05, ALZ12F05). Electrical and mechanical specifications are identical between tube and bulk variants of the same part number base. Packaging selection is determined by procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. ALZ11B05, ALZ11B05W, and ALZ12F05 carry ROHS3 compliance certification. ALZ12F05W carries RoHS compliance certification. Both certifications satisfy RoHS regulatory requirements.

Q: What is the significance of the 440VAC switching voltage rating on substitute parts?

A: The Panasonic substitute parts are rated for 440VAC maximum switching voltage, compared to 400VAC for the RTD14005. This 40VAC additional margin provides enhanced performance headroom in applications operating at or near the maximum switching voltage specification.

Q: Can I use ALZ12F05 in place of ALZ11B05?

A: Yes. ALZ12F05 is a direct functional substitute for ALZ11B05 with the added benefit of extended operating temperature range (-40°C to 105°C versus -40°C to 85°C) and Class F coil insulation. All other electrical specifications are identical.
