Substitute Part Grouping Explanation

Substitute parts for the 15723T2LC are identified based on electrical and mechanical parameter equivalence within the TE Connectivity Potter & Brumfield Relays product line. The substitution logic is based on the following critical parameters that must remain constant:

Electrical Parameters (Must Match):

• Coil Voltage: 120VAC
• Contact Form: 3PDT (3 Form C)
• Contact Rating (Current): 10 A
• Switching Voltage: 240VAC, 28VDC - Nom
• Load - Max Switching: 3.1VA
• Coil Type: Non Latching
• Coil Resistance: 1.7 kOhms
• Coil Current: 70.6 mA
• Must Operate Voltage: 102 VAC
• Operate Time: 20 ms
• Release Time: 10 ms
• Contact Material: Silver Cadmium Oxide (AgCdO)

Mechanical Parameters (Must Match):

• Mounting Type: Socketable
• Termination Style: Plug In, Quick Connect - 0.187" (4.7mm)
• Series: 157, CII

Environmental Parameters (Must Match):

• Operating Temperature Range: -45°C ~ 60°C
• Approval Agency: CSA, UR

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes for the 15723T2LC in switching applications.

Parameter Comparison

Engineering Selection Recommendations

The 15723T2LC and 15723T200 are parametric equivalents with identical electrical and mechanical specifications. Both parts are active products from TE Connectivity Potter & Brumfield Relays within the 157 and CII series, featuring the same 3PDT contact configuration, 120VAC coil voltage, 10 A contact rating, and socketable mounting with quick-connect termination.

Compliance Considerations:

The primary distinction between these parts relates to regulatory compliance status. The 15723T2LC carries ROHS3 Compliant certification, while the 15723T200 is RoHS non-compliant. Additionally, the 15723T2LC lists REACH Status as Vendor Undefined, whereas the 15723T200 is marked as REACH Affected. These differences are significant for applications subject to European Union environmental regulations or customer-specific compliance requirements.

For applications requiring RoHS3 compliance or operating in regulated markets with REACH restrictions, the 15723T2LC is the appropriate selection. For applications without such regulatory constraints, the 15723T200 provides functional equivalence with higher current inventory availability (1148 pieces versus 983 pieces).

Both parts carry CSA and UR approval certifications and operate across the identical temperature range of -45°C to 60°C, ensuring thermal compatibility in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the 15723T200 be used as a direct replacement for the 15723T2LC in all applications?

A: The 15723T200 is a parametric electrical and mechanical equivalent to the 15723T2LC. All switching characteristics, coil specifications, contact ratings, and timing parameters are identical. However, regulatory compliance differences exist. The 15723T2LC is ROHS3 Compliant while the 15723T200 is RoHS non-compliant. Applications subject to RoHS3 requirements must use the 15723T2LC. For applications without such regulatory mandates, the 15723T200 provides functional equivalence.

Q: What are the key electrical parameters that define substitution eligibility for this relay?

A: Substitution eligibility is determined by matching the following electrical parameters: 120VAC coil voltage, 3PDT (3 Form C) contact form, 10 A contact rating, 240VAC/28VDC nominal switching voltage, 3.1VA maximum switching load, 70.6 mA coil current, 1.7 kOhms coil resistance, 102 VAC must-operate voltage, 20 ms operate time, and 10 ms release time. All substitute parts must maintain these specifications exactly.

Q: Are the mounting and termination characteristics identical between the 15723T2LC and 15723T200?

A: Yes. Both parts feature socketable mounting type and identical termination style: Plug In, Quick Connect with 0.187" (4.7mm) connector dimensions. Socket compatibility and circuit board integration are equivalent between these parts.

Q: What is the significance of the RoHS and REACH compliance differences?

A: RoHS (Restriction of Hazardous Substances) compliance restricts the use of specific hazardous materials in electrical and electronic equipment sold in the European Union. The 15723T2LC is ROHS3 Compliant, meeting current EU standards. The 15723T200 is RoHS non-compliant and may not be suitable for EU market applications or customers with RoHS compliance mandates. REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a separate EU chemical safety regulation. The 15723T2LC lists REACH Status as Vendor Undefined, while the 15723T200 is marked as REACH Affected, indicating potential chemical substance restrictions. Component selection should align with applicable regulatory requirements for the target market.

Q: Do both relays operate across the same temperature range?

A: Yes. Both the 15723T2LC and 15723T200 operate across the identical temperature range of -45°C to 60°C, ensuring thermal compatibility in equivalent environmental conditions.

Q: What is the difference between the base product number and the specific part numbers?

A: The base product number 15723T identifies the core relay design within the TE Connectivity Potter & Brumfield Relays product family. The specific part numbers 15723T2LC and 15723T200 represent distinct manufacturing variants or packaging configurations of this base design. Both variants maintain the same electrical and mechanical specifications but differ in compliance certifications and inventory availability.

Q: Are there any operational differences in switching speed or timing between these parts?

A: No. Both parts exhibit identical operate time (20 ms) and release time (10 ms), ensuring equivalent switching performance in circuit applications. Coil response characteristics and contact transition timing are identical.
