TE Connectivity Potter & Brumfield Relay 2-1393217-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Potter & Brumfield Relay 2-1393217-7 is a general purpose SPST-NO (Single Pole Single Throw, Normally Open) relay with a 12VDC coil rated for 6A switching capacity. This through-hole mounted relay operates at a maximum switching voltage of 400VAC and features a sealed, fully enclosed design with Class F coil insulation. The part is classified as obsolete, necessitating identification of active equivalent components for continued system support and new design implementations. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution of the obsolete 2-1393217-7 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 1956226-1 maintains identical specifications for coil voltage (12VDC), contact form (SPST-NO), current rating (6A), switching voltage (400VAC maximum), mounting configuration (through-hole with PC pin termination), coil resistance (720 Ohms), and thermal operating range (-40°C to 70°C). Both relays share the same series designation (RE, SCHRACK) and belong to the general purpose relay category. The substitute part is manufactured by the same supplier (TE Connectivity Potter & Brumfield Relays) and carries active product status with full RoHS3 compliance and REACH compliance documentation. Substitution is valid where the original part number 2-1393217-7 is specified, provided the system design accommodates the substitute's active product status and updated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1956226-1 is the direct equivalent for the obsolete 2-1393217-7. Selection of the substitute is based on the following engineering criteria:

Product Status: The main part 2-1393217-7 carries obsolete status, making continued procurement impossible for new designs or system replenishment. The substitute 1956226-1 maintains active product status with confirmed inventory availability (3063 pieces in stock).

Electrical Equivalence: All critical electrical parameters are identical between the main part and substitute, including coil voltage, contact rating, switching voltage, coil resistance, and timing specifications. This ensures direct functional replacement without circuit modification.

Compliance and Certifications: The substitute part carries ROHS3 compliance and REACH compliance documentation, meeting current regulatory requirements for electronic component procurement. The main part does not specify these compliance statuses.

Mechanical Compatibility: Both parts share identical mounting configuration (through-hole), termination style (PC pin), and physical form factor, enabling direct board-level substitution without layout modification.

Supplier Continuity: Both parts are manufactured by TE Connectivity Potter & Brumfield Relays, ensuring consistent quality standards and technical support.

The substitute part 1956226-1 is suitable for direct replacement in all applications where 2-1393217-7 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can 1956226-1 be used as a direct replacement for 2-1393217-7 in existing designs?

A: Yes. The substitute part 1956226-1 maintains identical electrical specifications, coil voltage, contact rating, switching voltage, coil resistance, and timing parameters. The through-hole mounting and PC pin termination are identical, enabling direct board-level substitution without circuit or layout modification.

Q: What is the primary reason for substitution?

A: The main part 2-1393217-7 is classified as obsolete, making continued procurement unavailable. The substitute 1956226-1 is an active product with confirmed inventory availability and current compliance certifications.

Q: Are there differences in contact material between the two parts?

A: The main part does not specify contact material. The substitute part 1956226-1 uses Silver Nickel (AgNi) contact material. This material is standard for general purpose relays in this current and voltage class and does not affect functional compatibility.

Q: What compliance certifications does the substitute part carry?

A: The substitute part 1956226-1 is ROHS3 compliant and REACH compliant. These certifications meet current regulatory requirements for electronic component procurement in regulated markets.

Q: Is the packaging different between the main part and substitute?

A: The main part is specified with "-" packaging notation. The substitute part 1956226-1 is supplied in bulk packaging. Both parts are identical in form factor and mounting configuration; packaging difference refers only to the quantity and container format for procurement.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across the identical temperature range of -40°C to 70°C, ensuring thermal compatibility in all specified operating environments.

Q: What is the coil current requirement for both parts?

A: Both parts require 16.7 mA coil current at 12VDC nominal voltage, with a coil resistance of 720 Ohms. This ensures identical power supply requirements and circuit design parameters.

Q: Can the substitute part be used in new designs?

A: Yes. The substitute part 1956226-1 is an active product with full compliance certifications and is suitable for both replacement applications and new design implementations.
