LKP1AF-6V Equivalent & Substitute Parts

Part Overview

The LKP1AF-6V is a general purpose relay manufactured by Panasonic Electric Works, configured as a SPST-NO (1 Form A) with a 6VDC coil and 10A contact rating. This through-hole mounted relay is designed for applications requiring single-pole, single-throw switching functionality at low DC voltages. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKP1AF-6V is determined by strict equivalence across the following critical parameters:

• Coil voltage: 6VDC (exact match required)
• Contact form: SPST-NO (1 Form A) (exact match required)
• Contact rating: 10A minimum (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: PC pin (exact match required)
• Coil resistance: 68 Ohms (exact match required)
• Must operate and release voltages: 4.2 VDC and 0.6 VDC respectively (exact match required)
• Contact material: Silver Tin Oxide (AgSnO) (exact match required)
• Seal rating: Sealed - Flux protection (exact match required)

The JW1AFHN-DC6V-F meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The JW1AFHN-DC6V-F is a direct functional equivalent to the LKP1AF-6V and is the appropriate substitute for applications requiring replacement of the obsolete LKP1AF-6V. Both relays are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications across all critical parameters.

The JW1AFHN-DC6V-F offers the advantage of active product status, ensuring continued availability and supply chain support. The operating temperature range of the JW1AFHN-DC6V-F (-40°C to 60°C) is narrower than the LKP1AF-6V (-40°C to 70°C); applications requiring operation above 60°C must be evaluated against specific system requirements.

Both parts are RoHS compliant and carry identical coil voltage, contact rating, switching voltage (30VDC), coil resistance, and timing specifications. The AC switching voltage specification differs slightly (250VAC vs 277VAC maximum), with the JW1AFHN-DC6V-F rated for 250VAC maximum.

Frequently Asked Questions (FAQ)

Q: Can the JW1AFHN-DC6V-F directly replace the LKP1AF-6V in existing PCB assemblies?

A: Yes. Both relays feature identical through-hole PC pin termination and coil voltage specifications. Physical footprint compatibility should be confirmed by comparing mechanical drawings, as pin spacing and body dimensions determine direct board-level substitution.

Q: What is the significance of the product status difference (Obsolete vs Active)?

A: The LKP1AF-6V is obsolete and no longer manufactured. The JW1AFHN-DC6V-F is an active product with ongoing manufacturing and supply availability. For new designs or ongoing production, the JW1AFHN-DC6V-F is the appropriate selection.

Q: Are there differences in switching voltage ratings between these relays?

A: The LKP1AF-6V is rated for 277VAC maximum AC switching voltage, while the JW1AFHN-DC6V-F is rated for 250VAC maximum. Both are rated identically for 30VDC maximum DC switching voltage. Applications operating at AC voltages between 250VAC and 277VAC must be evaluated against specific circuit requirements.

Q: What is the operating temperature consideration for substitution?

A: The LKP1AF-6V operates across -40°C to 70°C, while the JW1AFHN-DC6V-F operates across -40°C to 60°C. Applications requiring operation above 60°C must confirm compatibility with the narrower temperature range of the substitute part.

Q: Are both relays RoHS compliant?

A: Yes. Both the LKP1AF-6V and JW1AFHN-DC6V-F are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What packaging differences exist between these parts?

A: The LKP1AF-6V is supplied in standard packaging, while the JW1AFHN-DC6V-F is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical functionality.
