ACJ5212P Equivalent & Substitute Parts Reference

Part Overview

The ACJ5212P 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 applications requiring sealed, flux-protected construction with through-hole PC pin termination. The part is currently in Last Time Buy status, making identification of functionally equivalent alternatives necessary for continued design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACJ5212P is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Coil voltage: 12VDC (exact match required)
• Contact form: SPDT (1 Form C) x 2 (exact configuration required)
• Contact rating: 20A minimum (equal or higher acceptable)
• Switching voltage: 14VDC nominal (within automotive specification)
• Operate and release times: 10 ms (timing-critical applications)

Mechanical & Environmental Requirements:

• Mounting type: Through Hole (PCB layout compatibility)
• Termination style: PC Pin (connector compatibility)
• Operating temperature range: Must encompass -40°C to 85°C minimum
• Sealed construction: Required for automotive flux protection

Compliance Requirements:

• RoHS compliance maintained
• Cadmium-free contact material preferred for environmental standards

The ACTE5R3 meets all substitution criteria within these parameters.

Engineering Selection Recommendations

ACJ5212P Status Consideration: The ACJ5212P is designated Last Time Buy, indicating end-of-life status. New designs and replenishment procurement should transition to the ACTE5R3, which carries Active part status from the same manufacturer.

Compliance & Certification: Both parts maintain RoHS compliance. The ACTE5R3 provides extended operating temperature range (-40°C to 110°C versus -40°C to 85°C), offering additional thermal margin for automotive applications without compromising the original specification envelope.

Electrical Performance: Coil current, voltage, resistance, and power dissipation parameters are within normal manufacturing tolerance bands. Switching characteristics (operate/release times) are identical. The ACTE5R3 demonstrates marginally improved release voltage performance (0.8VDC versus 1VDC), which is favorable for circuit reliability.

Mechanical Compatibility: Both relays share identical through-hole PC pin termination and mounting configuration, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can ACTE5R3 be used as a direct replacement for ACJ5212P in existing designs?

A: Yes. The ACTE5R3 meets all electrical, mechanical, and environmental specifications required by the ACJ5212P. No circuit modifications or PCB layout changes are necessary. Both parts are manufactured by Panasonic Electric Works with identical contact form (SPDT x 2), coil voltage (12VDC), contact rating (20A), and termination style (PC Pin through-hole).

Q: What is the difference in operating temperature range?

A: The ACJ5212P operates from -40°C to 85°C, while the ACTE5R3 extends to 110°C. For automotive applications operating within the original -40°C to 85°C envelope, both parts are equivalent. The ACTE5R3 provides additional thermal headroom for high-temperature environments.

Q: Are there differences in coil current or power consumption?

A: Coil current differs slightly: ACJ5212P at 53.3 mA versus ACTE5R3 at 54.5 mA. This 1.2 mA difference (approximately 2.3%) is within normal manufacturing tolerance and does not affect circuit design. Coil power consumption is similarly comparable (640 mW versus 655 mW).

Q: Do both relays use the same contact material?

A: Both use silver alloy contacts. The ACJ5212P specifies cadmium-free silver alloy, while the ACTE5R3 specifies silver alloy. Both formulations are suitable for automotive switching applications and meet environmental standards.

Q: What is the packaging format for both parts?

A: Both the ACJ5212P and ACTE5R3 are supplied in tube packaging for through-hole mounting applications.

Q: Why is ACJ5212P being discontinued?

A: The ACJ5212P is in Last Time Buy status, indicating the manufacturer is phasing out this model. The ACTE5R3 from the same manufacturer (Panasonic Electric Works) provides equivalent functionality with Active part status, ensuring long-term availability and supply chain continuity.
