Engineering Selection Recommendations

All three parts—7-1415899-2, 4-1415899-9, and 9-1415899-4—are parametrically equivalent and fully interchangeable for applications requiring a 12VDC SPST-NO general purpose relay with 16A contact rating and 400VAC maximum switching voltage. Each part is Active in product status, ROHS3 compliant, and REACH unaffected, meeting current regulatory requirements for electronic component deployment.

Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical performance differences. All parts are manufactured by TE Connectivity Potter & Brumfield Relays and maintain identical performance characteristics across the specified operating temperature range of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can 4-1415899-9 be used as a direct replacement for 7-1415899-2?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including coil voltage, contact form, current rating, switching voltage, operating temperature range, and timing characteristics. Direct substitution is supported without circuit modification.

Q: Are there any differences in compliance or certification between these parts?

A: No. All three parts maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Regulatory compliance is consistent across all substitute options.

Q: What is the difference between the base product numbers RZ03-1A4, RZ03-1A3, and RZ0H-1A4?

A: Base product numbers identify internal TE Connectivity product line variants. The provided substitute parts share identical electrical and mechanical parameters despite different base product designations. The base product number does not affect functional equivalence for substitution purposes.

Q: Can these relays be used interchangeably in through-hole PCB applications?

A: Yes. All parts feature identical through-hole mounting type and PC pin termination style, enabling direct PCB footprint compatibility without layout modification.

Q: What is the operating voltage range for these relays?

A: The must operate voltage is 8.4 VDC and the must release voltage is 1.2 VDC. The nominal coil voltage is 12VDC. These parameters are identical across all substitute parts.

Q: Are there inventory differences between these substitute parts?

A: Yes. Inventory levels vary: 7-1415899-2 has 765 pieces, 4-1415899-9 has 6,930 pieces, and 9-1415899-4 has 26,130 pieces in stock. Inventory status does not affect electrical or mechanical equivalence.
