Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 2071504-1 are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Coil Voltage: 12VDC (exact match required)
• Contact Form: SPST-NO (1 Form A) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Coil Type: Non Latching (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Contact Material: Silver Tin Oxide (AgSnO) (exact match required)
• Coil Insulation: Class F (exact match required)

Allowable Parameter Variations:

• Contact Rating (Current): Substitute must equal or exceed 31A
• Switching Voltage - Max: Substitute must equal or exceed 277VAC
• Coil Current: Minor variations acceptable within normal manufacturing tolerance
• Coil Resistance: Variations acceptable within normal manufacturing tolerance
• Operate/Release Time: Variations acceptable within normal manufacturing tolerance
• Must Operate/Release Voltage: Variations acceptable within normal manufacturing tolerance

The American Zettler AZSR131-1AE-12D meets all critical matching parameters and exceeds allowable current and voltage ratings, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The American Zettler AZSR131-1AE-12D is a qualified substitute for the obsolete TE Connectivity 2071504-1 based on the following engineering factors:

Product Status Consideration: The TE Connectivity 2071504-1 is classified as Obsolete, making the American Zettler AZSR131-1AE-12D an Active product alternative necessary for continued component availability.

Electrical Compatibility: The substitute part maintains identical coil voltage (12VDC), contact form (SPST-NO), and switching voltage rating (277VAC). The contact current rating of 35A exceeds the original 31A specification, providing additional capacity margin.

Mechanical Compatibility: Both relays feature identical through-hole mounting and PC pin termination, ensuring direct board-level compatibility without layout modifications.

Regulatory Compliance: The American Zettler AZSR131-1AE-12D holds ROHS3 Compliant status and carries multiple approval agencies (CQC, cURus, TUV), meeting current regulatory requirements. The original part holds RoHS Compliant status.

Thermal and Environmental Performance: Operating temperature range, coil insulation class, and contact material specifications are identical between both parts, ensuring equivalent performance across specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the American Zettler AZSR131-1AE-12D directly replace the TE Connectivity 2071504-1 in existing designs?

A: Yes. Both relays share identical coil voltage, contact form, mounting type, termination style, and operating temperature range. The substitute part's 35A contact rating exceeds the original 31A specification, providing functional compatibility without circuit modifications.

Q: What is the difference in coil current between the two relays?

A: The American Zettler AZSR131-1AE-12D draws 116.5 mA compared to the TE Connectivity part's 107.1 mA. This 9.4 mA difference falls within normal manufacturing tolerance for relay coils and does not affect circuit design or power supply requirements.

Q: Are there packaging differences between these parts?

A: The TE Connectivity 2071504-1 packaging is listed as standard, while the American Zettler AZSR131-1AE-12D is supplied in Tray packaging. Both maintain identical through-hole PC pin termination suitable for standard PCB assembly processes.

Q: What is the significance of the higher Must Operate Voltage in the substitute part?

A: The American Zettler AZSR131-1AE-12D requires 8.4 VDC to operate compared to 7.8 VDC for the original part. This 0.6 VDC difference is within acceptable tolerance for 12VDC coil relays and does not impact standard circuit operation where nominal 12VDC supply is provided.

Q: Do both relays have identical switching performance?

A: Yes. Both relays feature 20 ms operate time and 10 ms release time, ensuring identical switching response characteristics for circuit applications.

Q: What regulatory approvals does the substitute part carry?

A: The American Zettler AZSR131-1AE-12D holds CQC, cURus, and TUV approvals, meeting international regulatory standards. The original TE Connectivity part does not list specific approval agencies in the provided specifications.
