Substitute Part Grouping Explanation

Substitution of the PC565-1C-12-X is determined by strict equivalence in the following critical parameters:

Electrical Compatibility:

Coil voltage: 12VDC (exact match required)
Coil current: 53.3 mA (exact match required)
Coil resistance: 225 Ohms (exact match required)
Contact form: SPDT (1 Form C) configuration
Contact rating: 25 A minimum

Mechanical Compatibility:

Mounting type: Through Hole
Termination style: PC Pin
Packaging: Tube

Environmental & Operational:

Sealed construction (fully sealed)
Non-latching coil type
Operating temperature range: minimum -40°C to 85°C

The substitute part A161CS12VDC.64 meets all critical electrical parameters and mechanical requirements. Variations in switching voltage maximum, must-operate voltage, must-release voltage, and operating temperature upper limit do not preclude substitution when the substitute part specifications exceed or equal the minimum requirements of the primary application.

Engineering Selection Recommendations

Primary Part: PC565-1C-12-X

The PC565-1C-12-X remains the primary selection when Picker Components inventory is available and application requirements are limited to the specified -40°C to 85°C operating range. This part carries ROHS3 compliance and is actively produced.

Substitute Part: A161CS12VDC.64

The A161CS12VDC.64 manufactured by CIT Relay and Switch is a direct electrical and mechanical substitute. This part is suitable for selection when:

PC565-1C-12-X inventory is unavailable
Extended operating temperature range to 105°C is beneficial to application design margins
Enhanced contact material composition (AgSnOInO) is acceptable for the application
RoHS compliance (general) meets regulatory requirements

Both parts carry identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications, indicating equivalent export and tariff treatment. Both maintain REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can A161CS12VDC.64 be used as a direct replacement for PC565-1C-12-X in automotive applications?

A: Yes. Both relays share identical coil voltage (12VDC), coil current (53.3 mA), contact form (SPDT), contact rating (25A), mounting type (through hole), and termination style (PC pin). Electrical and mechanical compatibility is confirmed.

Q: What are the differences between these two relays?

A: The A161CS12VDC.64 provides higher switching voltage rating (20VDC vs. 16VDC), higher must-operate voltage (8.4VDC vs. 7.2VDC), higher must-release voltage (1.2VDC vs. 1VDC), extended operating temperature range (-40°C to 105°C vs. -40°C to 85°C), and enhanced contact material composition (AgSnOInO vs. AgSnO). These represent performance enhancements rather than limitations.

Q: Are both parts available in the same packaging?

A: Yes. Both PC565-1C-12-X and A161CS12VDC.64 are supplied in tube packaging.

Q: Do both relays meet the same regulatory standards?

A: Both parts are RoHS compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8536.41.0050. Regulatory treatment is equivalent.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on availability and supply chain considerations. The A161CS12VDC.64 offers extended temperature range and enhanced contact material, which may provide additional design margin in demanding automotive environments.

Q: Is the contact material difference significant?

A: The A161CS12VDC.64 uses Silver Tin Oxide Indium Oxide (AgSnOInO) versus Silver Tin Oxide (AgSnO) in the PC565-1C-12-X. Both materials are suitable for 25A automotive switching applications. The enhanced material in the substitute part does not create incompatibility.

Q: Can these relays be intermixed in existing inventory?

A: Yes. Both relays are mechanically and electrically interchangeable. They share identical through-hole PC pin termination and can be used interchangeably in the same circuit board layout.
