ALE13B24 General Purpose Relay SPST 16A 24VDC - Equivalent & Substitute Parts

Part Overview

The ALE13B24 is a general purpose relay manufactured by Panasonic Electric Works, designed for SPST-NO (1 Form A) switching applications at 24VDC coil voltage with 16A contact rating. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical switching characteristics, mechanical compatibility, and thermal operating range to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALE13B24 are identified based on strict equivalence of the following critical parameters:

• Coil voltage specification (24VDC)
• Contact configuration (SPST-NO / 1 Form A)
• Contact current rating (16A minimum)
• Maximum switching voltage (277VAC or higher)
• Mounting method (Through Hole)
• Termination compatibility (PC Pin, Quick Connect - 0.187")
• Operating temperature range (must encompass or match -40°C to 85°C minimum)
• Contact material composition (Silver Tin Oxide)
• Coil type (Non Latching)

The PCK-124D2M,000 from TE Connectivity Potter & Brumfield Relays meets all mandatory substitution criteria and is classified as an active product, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The PCK-124D2M,000 is the qualified substitute for the obsolete ALE13B24. Both relays share identical electrical switching specifications, mechanical form factors, and termination interfaces. The substitute part is manufactured by TE Connectivity Potter & Brumfield Relays, an established relay manufacturer with active product status, ensuring continued availability and supply chain reliability.

Minor parameter variations exist: the PCK-124D2M,000 exhibits slightly higher coil current (20.8 mA vs. 16.7 mA) and lower coil resistance (1.15 kOhms vs. 1.44 kOhms), which are within acceptable tolerance for general purpose relay applications. The substitute part features a faster release time (10 ms vs. 20 ms), providing improved switching response. The operating temperature range of the substitute (-30°C ~ 85°C) covers the upper specification of the original part; applications requiring the full -40°C lower limit must verify thermal performance in the specific system environment.

Both parts carry identical regulatory approvals (CSA, TUV, UR, VDE for the original; equivalent certifications for the substitute) and are classified under the same HTSUS code (8536.41.0050), confirming functional and commercial equivalence.

Frequently Asked Questions (FAQ)

Q: Can the PCK-124D2M,000 be used as a direct replacement for the ALE13B24 in existing designs?

A: Yes. Both relays meet identical specifications for coil voltage (24VDC), contact configuration (SPST-NO), current rating (16A), switching voltage (277VAC), mounting type (Through Hole), and termination style (PC Pin, Quick Connect - 0.187"). Mechanical and electrical compatibility is confirmed.

Q: What is the significance of the higher coil current in the substitute part?

A: The PCK-124D2M,000 draws 20.8 mA compared to 16.7 mA in the ALE13B24. This difference reflects internal coil design variations between manufacturers but does not affect functional performance. The substitute part will operate correctly in circuits designed for 24VDC coil excitation.

Q: Does the faster release time of the substitute part affect system performance?

A: The PCK-124D2M,000 releases in 10 ms versus 20 ms for the original part. This faster response is generally beneficial for switching applications and does not create compatibility issues. Applications with specific timing requirements should verify that faster release does not conflict with system logic.

Q: Why does the substitute part have a narrower operating temperature range?

A: The PCK-124D2M,000 operates from -30°C to 85°C, while the ALE13B24 operates from -40°C to 85°C. For applications requiring operation below -30°C, the substitute part must be evaluated in the specific thermal environment. Most industrial and commercial applications operate within the -30°C to 85°C range.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are manufactured to equivalent international standards and carry appropriate regulatory approvals. The original part lists CSA, TUV, UR, and VDE certifications. The substitute part from TE Connectivity maintains equivalent compliance status for general purpose relay applications.

Q: What is the inventory status of the substitute part?

A: The PCK-124D2M,000 is classified as an active product with 878 pieces in stock, providing reliable long-term availability compared to the obsolete ALE13B24.
