LKG1AF-12V-16 Equivalent & Substitute Parts

Part Overview

The LKG1AF-12V-16 is a general purpose relay manufactured by Panasonic Electric Works, configured as a single-pole single-throw normally open (SPST-NO) contact form with a 12VDC coil and 16A contact rating. This through-hole mounted relay is designed for general switching applications up to 277VAC maximum switching voltage.

The LKG1AF-12V-16 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKG1AF-12V-16 is determined by the following critical parameters:

• Coil Voltage: 12VDC (exact match required)
• Contact Form: SPST-NO (1 Form A) (exact match required)
• Contact Rating: 16A minimum (equal or higher acceptable)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Seal Rating: Sealed - Flux Protection (exact match required)

The ALZN5B12W meets all substitution criteria. It maintains identical coil voltage, contact form, current rating, mounting configuration, and termination style. The substitute part operates within compatible electrical parameters and provides enhanced switching voltage capability (440VAC vs. 277VAC) and improved temperature range (-40°C ~ 85°C vs. -40°C ~ 70°C).

Parameter Comparison

Engineering Selection Recommendations

The ALZN5B12W is a direct substitute for the LKG1AF-12V-16. Both relays are manufactured by Panasonic Electric Works and share identical core electrical specifications: 12VDC coil voltage, SPST-NO contact form, 16A contact rating, through-hole mounting, and PC pin termination.

The ALZN5B12W is classified as active product status, ensuring ongoing availability and supply chain support. The substitute part carries ROHS3 compliance, exceeding the RoHS compliance of the original part. Both parts maintain EAR99 export classification and identical HTSUS codes.

The ALZN5B12W provides enhanced performance characteristics: maximum switching voltage of 440VAC (compared to 277VAC), extended operating temperature range to 85°C (compared to 70°C), reduced coil current draw (33.3 mA vs. 44.2 mA), and faster release time (5 ms vs. 20 ms). These improvements do not compromise compatibility with existing circuit designs specified for the LKG1AF-12V-16.

Frequently Asked Questions (FAQ)

Q: Can the ALZN5B12W directly replace the LKG1AF-12V-16 in existing applications?

A: Yes. Both relays share identical coil voltage (12VDC), contact form (SPST-NO), current rating (16A), mounting type (through-hole), and termination style (PC pin). The substitute part is electrically and mechanically compatible with designs specified for the LKG1AF-12V-16.

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

A: The ALZN5B12W offers higher maximum switching voltage (440VAC vs. 277VAC), extended operating temperature range (-40°C to 85°C vs. -40°C to 70°C), lower coil current consumption (33.3 mA vs. 44.2 mA), and faster release time (5 ms vs. 20 ms). These represent performance enhancements rather than compatibility limitations.

Q: Why is the LKG1AF-12V-16 classified as obsolete?

A: The LKG1AF-12V-16 is no longer in active production. The ALZN5B12W from the same manufacturer provides equivalent functionality with improved specifications and active product status.

Q: Are there any compliance or certification differences?

A: The ALZN5B12W carries ROHS3 compliance, which supersedes the RoHS compliance of the LKG1AF-12V-16. Both parts maintain identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications. The ALZN5B12W includes cURus and VDE approval agency certifications.

Q: Will the lower coil current of the ALZN5B12W affect circuit design?

A: No. The lower coil current (33.3 mA vs. 44.2 mA) of the ALZN5B12W represents reduced power consumption. Existing driver circuits designed for the LKG1AF-12V-16 will operate the substitute part without modification.

Q: Are the PC pin configurations identical?

A: Yes. Both relays use PC pin termination style and maintain the same through-hole mounting configuration, ensuring direct PCB compatibility without layout modifications.
