ALD14H Equivalent & Substitute Parts

Part Overview

The ALD14H is a general purpose relay manufactured by Panasonic Electric Works, featuring SPST-NO (1 Form A) contact configuration with 4.5VDC coil voltage and 3A contact rating. This through-hole mounted relay is designed for general switching applications with maximum switching capacity of 831VA at 277VAC or 90W at 30VDC.

The ALD14H 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 component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALD14H are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Contact form: SPST-NO (1 Form A)
• Mounting type: Through Hole
• Termination style: PC Pin
• Contact material: Silver Nickel (AgNi)
• Coil type: Non Latching

Secondary Compatibility Criteria:

• Contact rating current: Equal to or greater than 3A
• Switching voltage: Equal to or greater than 277VAC / 30VDC
• Operating temperature range: Must encompass or exceed -40°C ~ 70°C
• Coil voltage: Acceptable within system design parameters

Two substitute parts meet these criteria with varying degrees of parameter alignment:

1. ALDP105W (Direct Manufacturer Substitute): Same manufacturer (Panasonic Electric Works), same contact form, same mounting and termination. Higher current rating (5A), higher coil voltage (5VDC), extended temperature range (-40°C ~ 85°C), and active product status.

2. PCJ-124D3MH,301 (Similar Manufacturer Substitute): Different manufacturer (TE Connectivity Potter & Brumfield Relays), same contact form, same mounting and termination. Identical current rating (3A), different coil voltage (24VDC), sealed construction, and obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

ALDP105W is the preferred substitute for new designs and ongoing production. This part is manufactured by the same supplier (Panasonic Electric Works), maintains identical contact form and mounting configuration, and carries active product status ensuring long-term availability. The higher current rating (5A versus 3A) provides design margin for switching applications. The 5VDC coil voltage is compatible with standard logic and control circuits. Extended operating temperature range (-40°C ~ 85°C) exceeds the original specification. RoHS3 compliance and active inventory status support supply chain continuity.

PCJ-124D3MH,301 is an alternative substitute where coil voltage requirements align with 24VDC systems. This part maintains identical current rating and contact form but differs significantly in coil voltage and resistance. The sealed construction provides enhanced environmental protection. However, obsolete product status limits long-term availability. This substitute is suitable only for legacy system maintenance where 24VDC coil supply is already established.

Frequently Asked Questions (FAQ)

Q: Can ALDP105W directly replace ALD14H in existing circuits?

A: ALDP105W is functionally compatible for SPST-NO switching applications. The 5VDC coil voltage requires circuit verification to confirm adequate drive capability. The higher current rating (5A) is backward compatible with 3A load requirements. Mechanical fit is identical (through-hole PC pin termination). Electrical performance parameters (operate time, release time, contact material) are equivalent.

Q: What is the primary difference between ALDP105W and PCJ-124D3MH,301?

A: The primary difference is coil voltage: ALDP105W operates at 5VDC while PCJ-124D3MH,301 operates at 24VDC. This difference requires different circuit design and power supply architecture. ALDP105W is from the original manufacturer (Panasonic) with active status. PCJ-124D3MH,301 is from a different manufacturer (TE Connectivity) with obsolete status. Both maintain identical contact form and current rating.

Q: Are there packaging differences between these substitutes?

A: ALD14H packaging is specified as "-" (not detailed). ALDP105W is supplied in Tray packaging. PCJ-124D3MH,301 is supplied in Tray packaging. Both substitute parts use standard tray packaging suitable for automated assembly and manual handling.

Q: Which substitute has better long-term availability?

A: ALDP105W has superior long-term availability. It carries active product status with 25,340 pieces in current inventory. PCJ-124D3MH,301 is obsolete with 16,276 pieces in inventory. For new designs and production planning, ALDP105W is the recommended choice.

Q: Do these substitutes have different compliance certifications?

A: ALD14H carries CSA, TUV, UR, and VDE approvals. ALDP105W carries CQC, cURuus, and VDE approvals with RoHS3 compliance. PCJ-124D3MH,301 carries RoHS3 compliance. Compliance requirements for your application must be verified against these certifications.
