Equivalent & Substitute Parts for TE Connectivity D3213 Telecom Relay

Part Overview

The TE Connectivity Potter & Brumfield D3213 is a telecom-grade DPDT relay with 2A contact rating and 48VDC coil voltage. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing system support and new designs. The D3213 features through-hole mounting, PC pin termination, and operates across the industrial temperature range of -40°C to 85°C. Equivalent parts must maintain functional compatibility across critical electrical parameters including coil voltage, contact form, contact rating, and switching characteristics.

Substitute Part Grouping Explanation

Substitute parts for the D3213 are classified into two categories based on parametric alignment with the main part specifications:

Parametric Equivalent Classification: Parts that maintain all critical electrical parameters including coil voltage (48VDC), contact form (DPDT), contact rating (2A), switching voltage capability, mounting type (through hole), and termination style (PC pin). These parts operate under identical circuit conditions and require no design modification.

Direct Manufacturer Substitute Classification: Parts from alternative manufacturers that satisfy all critical parameters but may exhibit minor variations in secondary characteristics such as coil current, operate/release timing, operating temperature range, or contact material composition. These parts function as direct replacements within specified application constraints.

The following critical parameters determine substitution eligibility:

• Coil voltage: 48VDC (mandatory match)
• Contact form: DPDT (mandatory match)
• Contact rating: 2A minimum (mandatory match)
• Mounting type: Through hole (mandatory match)
• Termination style: PC pin (mandatory match)
• Coil type: Non latching (mandatory match)

Engineering Selection Recommendations

D3013 (Parametric Equivalent - Recommended Primary Substitute)

The TE Connectivity D3013 is the preferred substitute for the obsolete D3213. This part maintains identical electrical specifications across all critical parameters: 48VDC coil voltage, DPDT contact form, 2A contact rating, 250VAC/220VDC switching voltage, through-hole mounting, and PC pin termination. The D3013 operates within the same temperature range (-40°C to 85°C) and exhibits identical coil current (6.3 mA) and coil resistance (7.68 kOhms). The D3013 is classified as active product status, ensuring long-term availability and supply chain continuity. Both parts are manufactured by TE Connectivity within the AXICOM relay series, providing design continuity. The D3013 is RoHS compliant, supporting modern regulatory requirements.

TX2-48V (Direct Manufacturer Substitute - Alternative Option)

The Panasonic Electric Works TX2-48V functions as a direct substitute with full compatibility across critical electrical parameters. This part maintains 48VDC coil voltage, DPDT contact form, 2A contact rating, and through-hole PC pin termination. The TX2-48V exhibits lower coil current (5.6 mA versus 6.3 mA) and higher coil resistance (8.53 kOhms versus 7.68 kOhms), resulting in reduced power consumption. The must-operate voltage is specified at 36VDC, representing a 2.4VDC increase from the D3213 specification. The operating temperature range is limited to -40°C to 70°C, restricting use in applications requiring operation above 70°C. The TX2-48V includes sealed construction with fully sealed rating and is ROHS3 compliant. This part is suitable for applications where the reduced temperature range and alternative contact material composition (Silver/Gold versus Palladium/Ruthenium/Gold) are acceptable.

Product Status Consideration

The D3213 is obsolete, making the D3013 the recommended choice for new designs and ongoing production support due to its active status and identical parametric specifications. The TX2-48V provides an alternative for applications where Panasonic component qualification is established or where the lower coil current requirement provides system-level benefits.

Frequently Asked Questions (FAQ)

Q: Can the D3013 be used as a direct replacement for the D3213 without circuit modification?

A: Yes. The D3013 maintains identical coil voltage (48VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC/220VDC), coil current (6.3 mA), coil resistance (7.68 kOhms), must-operate voltage (33.6VDC), must-release voltage (4.8VDC), operate time (4 ms), release time (3 ms), and operating temperature range (-40°C to 85°C). No circuit design changes are required.

Q: What are the key differences between the D3013 and TX2-48V?

A: Both parts satisfy critical electrical parameters for substitution. The D3013 is manufactured by TE Connectivity and maintains identical specifications to the D3213. The TX2-48V is manufactured by Panasonic and exhibits three notable differences: coil current is reduced to 5.6 mA (versus 6.3 mA), must-operate voltage is increased to 36VDC (versus 33.6VDC), and operating temperature range is limited to -40°C to 70°C (versus -40°C to 85°C). Contact material composition also differs, with TX2-48V using Silver/Gold versus the D3213/D3013 Palladium/Ruthenium/Gold combination.

Q: Is the TX2-48V suitable for applications requiring operation above 70°C?

A: No. The TX2-48V operating temperature range is specified as -40°C to 70°C. Applications requiring operation above 70°C must use the D3013, which operates to 85°C.

Q: Does the higher must-operate voltage of the TX2-48V (36VDC versus 33.6VDC) affect circuit design?

A: The TX2-48V requires 36VDC minimum to operate reliably, compared to 33.6VDC for the D3213 and D3013. In circuits where the coil voltage approaches the minimum operating threshold, this 2.4VDC difference may affect relay performance. Circuits designed for the D3213 or D3013 must be evaluated for compatibility with the TX2-48V higher operating voltage requirement.

Q: Are both substitute parts RoHS compliant?

A: Yes. The D3013 is RoHS compliant. The TX2-48V is ROHS3 compliant. Both parts satisfy current RoHS requirements.

Q: What is the packaging difference between the D3013 and TX2-48V?

A: The D3013 packaging is not specified in the provided data. The TX2-48V is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Can the D3013 and TX2-48V be used interchangeably in the same application?

A: Interchangeability depends on application-specific requirements. Both parts satisfy the critical electrical parameters (coil voltage, contact form, contact rating, switching voltage, mounting type, termination style). However, the TX2-48V exhibits a higher must-operate voltage (36VDC versus 33.6VDC) and a reduced operating temperature range (-40°C to 70°C versus -40°C to 85°C). Applications operating above 70°C or with coil voltages near the minimum threshold must use the D3013. For applications within the TX2-48V operating envelope, both parts are functionally equivalent.

Q: What is the inventory status of these substitute parts?

A: The D3013 has 864 pieces in stock. The TX2-48V has 2200 pieces in stock. Both parts are available for immediate procurement.
