AH1484-A Equivalent & Substitute Parts

Part Overview

The AH1484-A is a snap action switch manufactured by Panasonic Electric Works, configured as a single-pole double-throw (SPDT) device with a 1A current rating at 125V AC and 30V DC. This through-hole mounted switch features a lever with simulated roller actuator and is terminated via PC pins. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The AH15849-A qualifies as a direct functional equivalent to the AH1484-A based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

Circuit configuration must be SPDT with On-Momentary switch function. Current rating must be 1A for both AC and DC operation. Voltage ratings must match at 125V AC and 30V DC minimum. Actuator type must be lever with simulated roller. Mounting must be through-hole with PC pin termination. All mechanical parameters including operating force (26gf), release force (2.039gf), operating position (0.374"), pretravel (0.083"), differential travel (0.020"), and overtravel (0.020") must be identical. Operating temperature range must span -25°C to 85°C. Electrical life must be rated for 30,000 cycles minimum. Mechanical life must be rated for 1,000,000 cycles minimum.

The AH15849-A meets all these criteria and is currently in active production status with improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The AH15849-A is the appropriate substitute for the obsolete AH1484-A. Both components are manufactured by Panasonic Electric Works and share identical electrical and mechanical specifications. The AH15849-A offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the AH15849-A carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for modern applications. The packaging difference (tube for AH15849-A versus unspecified for AH1484-A) does not affect functional compatibility in through-hole circuit board applications.

Frequently Asked Questions (FAQ)

Q: Can the AH15849-A directly replace the AH1484-A in existing designs?

A: Yes. The AH15849-A is functionally identical to the AH1484-A across all electrical and mechanical parameters. Both are SPDT snap action switches with 1A/125V AC and 30V DC ratings, identical actuator characteristics, and matching mechanical life specifications. Direct substitution is valid for through-hole PCB applications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certifications. The AH1484-A is obsolete, while the AH15849-A is in active production. The AH15849-A includes ROHS3 compliance and REACH unaffected status. Packaging differs (tube for AH15849-A), but this does not affect electrical or mechanical performance.

Q: Are there any compatibility concerns with packaging?

A: The AH15849-A is supplied in tube packaging, whereas the AH1484-A packaging is not specified. For through-hole mounting applications, packaging format does not affect component functionality or PCB integration. Tube packaging is standard for snap action switches and presents no compatibility issues.

Q: What parameters must match for substitution to be valid?

A: Circuit configuration (SPDT), switch function (On-Momentary), current rating (1A AC/DC), voltage ratings (125V AC / 30V DC), actuator type (lever with simulated roller), mounting type (through-hole), termination style (PC pin), and all mechanical parameters including operating force, release force, travel distances, and life ratings must be identical.

Q: Is the AH15849-A suitable for new designs?

A: Yes. The AH15849-A is in active production status with current compliance certifications (ROHS3, REACH unaffected), making it the appropriate choice for new designs requiring SPDT snap action switches with these electrical and mechanical specifications.
