Substitute Part Grouping Explanation

Substitution eligibility for the ALZ22F05 is determined by strict equivalence across the following critical parameters:

Coil voltage: 5VDC (exact match required)
Contact form: SPST-NO (1 Form A) (exact match required)
Contact rating: 16A minimum (equal or higher acceptable)
Mounting type: Through Hole (exact match required)
Termination style: PC Pin (exact match required)
Coil type: Non Latching (exact match required)
Coil insulation: Class F (exact match required)
Must operate voltage: 4.6VDC (exact match required)
Must release voltage: 0.5VDC (exact match required)

Substitute parts are classified into two categories:

Parametric Equivalents (ALZ52F05, ALZ52F05T): Panasonic Electric Works parts with identical electrical and mechanical specifications. These represent direct functional replacements with active product status.

Similar Equivalents (6-1415899-4, RT334005, RZ03-1A3-D005, RZ03-1A4-D005): TE Connectivity Potter & Brumfield Relays with matching core functional parameters but minor variations in operating time, release time, contact material, or maximum operating temperature. These are functionally compatible within the specified parameter tolerances.

Engineering Selection Recommendations

Preferred Substitutes (Panasonic Electric Works):

ALZ52F05 and ALZ52F05T are direct parametric equivalents with identical electrical specifications to the ALZ22F05. Both parts maintain active product status and are available in higher inventory quantities. ALZ52F05T is packaged in tube format, while ALZ52F05 is available in tube packaging. Both are RoHS Compliant, providing regulatory advantage over the obsolete original part.

Alternative Substitutes (TE Connectivity Potter & Brumfield Relays):

RZ03-1A3-D005 is the recommended TE Connectivity alternative, offering the highest inventory availability (12,915 pcs) and matching contact material (Silver Tin Oxide) to the original ALZ22F05. This part maintains the full operating temperature range of -40°C to 85°C and is ROHS3 Compliant.

RT334005 provides sealed flux protection and operates within -40°C to 85°C, suitable for applications requiring enhanced environmental protection. Coil resistance (62 Ohms) closely matches the original specification.

6-1415899-4 maintains the full upper operating temperature of 105°C, matching the original ALZ22F05 thermal envelope. This part is appropriate for high-temperature applications where the TE Connectivity RZ and RT series temperature limitations are insufficient.

RZ03-1A4-D005 is functionally equivalent to RZ03-1A3-D005 with Silver Nickel contact material, offering alternative contact metallurgy for specific application requirements.

All substitute parts carry active product status and current RoHS compliance certifications, ensuring long-term procurement viability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can ALZ52F05 and ALZ52F05T be used interchangeably with ALZ22F05?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is packaging format (tube). Electrical performance, contact ratings, coil voltage, and operating temperature ranges are identical.

Q: What is the key difference between Panasonic and TE Connectivity substitutes?

A: Panasonic substitutes (ALZ52F05, ALZ52F05T) are direct parametric equivalents. TE Connectivity substitutes (RZ03-1A3-D005, RT334005, 6-1415899-4, RZ03-1A4-D005) are functionally compatible but exhibit variations in operate time (8 ms vs. 15 ms), release time (6 ms vs. 5 ms), and maximum operating temperature (85°C vs. 105°C for most TE models, except 6-1415899-4).

Q: Which substitute is best for high-temperature applications?

A: For applications requiring operation up to 105°C, use 6-1415899-4 (TE Connectivity). All other TE Connectivity substitutes are rated to 85°C maximum. Panasonic substitutes (ALZ52F05, ALZ52F05T) maintain the full -40°C to 105°C range.

Q: Are there RoHS compliance differences between substitutes?

A: ALZ52F05 and ALZ52F05T are RoHS Compliant. All TE Connectivity substitutes are ROHS3 Compliant. The original ALZ22F05 does not specify RoHS status. For applications requiring RoHS certification, all listed substitutes meet current regulatory requirements.

Q: What is the impact of different operate and release times?

A: Panasonic substitutes maintain 15 ms operate time and 5 ms release time, identical to the original. TE Connectivity substitutes operate faster (8 ms operate, 6 ms release). For timing-critical applications, verify that faster switching characteristics do not conflict with circuit design requirements.

Q: Can I use TE Connectivity parts in place of Panasonic parts?

A: Yes, with design verification. TE Connectivity substitutes meet all core functional requirements (5VDC coil, 16A SPST-NO contact, through-hole mounting). However, verify that differences in operate/release time, contact material (Silver Nickel vs. Silver Tin Oxide), and maximum operating temperature are acceptable for your specific application.

Q: What inventory considerations should guide my selection?

A: RZ03-1A3-D005 offers the highest inventory availability (12,915 pcs). ALZ52F05 and RT334005 each have approximately 1,100 pcs available. ALZ52F05T has 826 pcs. 6-1415899-4 has 989 pcs. Select based on procurement timeline and volume requirements.
