ACJ5112 Equivalent & Substitute Parts Reference

Part Overview

The ACJ5112 is an automotive relay manufactured by Panasonic Electric Works, configured as a dual SPDT (1 Form C x 2) switching device rated for 20A at 12VDC. This non-latching relay is designed for automotive electrical systems requiring sealed, fully protected operation across extended temperature ranges. The part is currently in Last Time Buy status, making identification of functionally equivalent alternatives essential for ongoing procurement and system design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACJ5112 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 12VDC (exact match required)
• Contact configuration: SPDT (1 Form C) x 2 (exact match required)
• Contact current rating: 20A minimum (equal or higher acceptable)
• Switching voltage: 14VDC nominal (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Operating temperature range: Must encompass or exceed -40°C to 85°C
• Contact material: Silver Alloy (cadmium-free preferred for RoHS compliance)
• Coil type: Non-latching (exact match required)

The ACTE5H2 qualifies as a substitute based on full alignment with these parameters. Both relays share identical electrical switching characteristics, contact configuration, and mechanical mounting specifications. Differences in coil current (75mA vs. 66.7mA), coil power (900mW vs. 800mW), and operating temperature upper limit (110°C vs. 85°C) do not preclude substitution, as the substitute meets or exceeds the minimum requirements for the application.

Parameter Comparison

Engineering Selection Recommendations

The ACTE5H2 is functionally equivalent to the ACJ5112 for automotive relay applications requiring dual SPDT switching at 20A and 12VDC. Both parts are manufactured by Panasonic Electric Works and share identical electrical switching parameters, contact configuration, and mechanical mounting specifications.

The ACJ5112 is RoHS Compliant with cadmium-free contact material. The ACTE5H2 specifications do not explicitly state RoHS compliance or cadmium-free status in the provided data. For applications with mandatory RoHS or cadmium-free requirements, compliance verification with the manufacturer is necessary before final selection.

The ACTE5H2 operates across a wider temperature range (-40°C to 110°C) compared to the ACJ5112 (-40°C to 85°C), providing additional thermal margin in high-temperature automotive environments. The slightly elevated coil current (75mA vs. 66.7mA) and coil power (900mW vs. 800mW) are within acceptable tolerances for 12VDC automotive circuits and do not introduce compatibility issues.

Frequently Asked Questions (FAQ)

Q: Can the ACTE5H2 directly replace the ACJ5112 in existing PCB designs?

A: Yes. Both relays share identical contact configuration (SPDT x 2), current rating (20A), coil voltage (12VDC), switching voltage (14VDC nominal), and mechanical mounting specifications (Through Hole, PC Pin termination). No PCB layout modifications are required.

Q: What is the significance of the coil current difference (66.7mA vs. 75mA)?

A: The ACTE5H2 requires 8.3mA additional coil current. For 12VDC automotive circuits, this represents a negligible increase in power consumption and does not affect circuit design or component selection. Verify that the driving circuit can supply the higher current if operating near maximum current limits.

Q: Does the extended operating temperature range of the ACTE5H2 affect reliability?

A: No. The ACTE5H2 operates from -40°C to 110°C, which encompasses the ACJ5112 range of -40°C to 85°C. The extended upper temperature limit provides additional thermal margin and does not compromise performance within the original ACJ5112 operating window.

Q: Are there packaging differences between these parts?

A: The ACJ5112 is supplied in Tube packaging. The ACTE5H2 is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes, as this may affect handling, storage, and component placement procedures.

Q: What compliance certifications should be verified before substitution?

A: The ACJ5112 is explicitly RoHS Compliant with cadmium-free contact material. The ACTE5H2 specifications do not include explicit RoHS or cadmium-free declarations in the provided data. Confirm compliance status with Panasonic Electric Works if your application requires RoHS certification or cadmium-free materials.

Q: Is the ACTE5H2 suitable for automotive applications?

A: Yes. The ACTE5H2 is designated as an automotive relay and meets the electrical and mechanical requirements for automotive switching applications. Both parts are designed for automotive environments and share equivalent performance characteristics.
