Substitute Part Grouping Explanation

Substitution of the obsolete 1-1571990-7 is based on strict electrical and mechanical parameter matching within the TE Connectivity TSP series. The substitute part TSPD11FGPCV0 maintains equivalence through the following criteria:

Electrical Parameters (Mandatory Match):

• SPDT circuit configuration
• 0.4VA current rating (AC/DC)
• 20V AC and DC voltage ratings
• 60,000 cycle electrical life
• On-Mom switch function

Mechanical Parameters (Mandatory Match):

• Round plunger actuator type
• Through-hole mounting configuration
• PC pin termination style
• Black actuator/cap color
• Process sealed features
• Operating temperature range of -30°C to 85°C

Compliance Parameters:

• EAR99 ECCN classification
• HTSUS code 8536.50.9031
• Vendor undefined REACH status
• Not applicable RoHS status

The substitute part differs only in mounting orientation (standard through-hole versus right-angle through-hole) and product status (active versus obsolete), with no impact on electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TSPD11FGPCV0 serves as the active production equivalent for the obsolete 1-1571990-7. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with TE Connectivity, ensuring continued availability, manufacturing support, and supply chain stability. The main part's obsolete classification creates supply risk and limits access to new inventory.

Electrical Specification Equivalence: Both components share identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (SPDT), and operational life (60,000 cycles). These parameters ensure direct functional replacement without circuit redesign or performance degradation.

Mechanical Compatibility: Identical actuator type, termination style, and operating temperature range confirm mechanical interchangeability. The difference in mounting orientation (right-angle versus standard through-hole) requires PCB layout evaluation but does not affect electrical performance.

Compliance and Certification: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications, maintaining regulatory compliance for export and tariff purposes. Vendor-undefined REACH status and not-applicable RoHS status are consistent across both components.

Inventory and Packaging: The substitute part is available in bulk packaging with 724 units in stock, compared to 847 units of the obsolete main part. Bulk packaging supports production requirements and reduces per-unit cost.

Frequently Asked Questions (FAQ)

Q: Can TSPD11FGPCV0 directly replace 1-1571990-7 in existing designs?

A: Electrical and functional replacement is direct. The mounting orientation difference (right-angle versus standard through-hole) requires PCB layout verification to confirm physical fit and connector alignment.

Q: What is the primary reason for substitution?

A: The 1-1571990-7 is classified as obsolete, creating long-term supply uncertainty. The TSPD11FGPCV0 is an active product with guaranteed availability and manufacturing support.

Q: Are the electrical specifications identical?

A: Yes. Both components are rated for 0.4VA at 20V AC/DC with SPDT configuration, 60,000 cycle electrical life, and On-Mom switch function.

Q: Does the mounting type difference affect electrical performance?

A: No. The difference between right-angle and standard through-hole mounting is mechanical only. Electrical performance, current rating, voltage rating, and circuit behavior remain identical.

Q: What packaging options are available for the substitute part?

A: TSPD11FGPCV0 is supplied in bulk packaging. The main part 1-1571990-7 was supplied in standard packaging format.

Q: Are compliance certifications maintained?

A: Yes. Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications, ensuring regulatory compliance for export and tariff applications.

Q: What is the operating temperature range for both parts?

A: Both components operate across -30°C to 85°C, with no temperature performance differences.

Q: Is there a difference in actuator appearance?

A: No. Both parts feature black round plunger actuators with no marking, maintaining visual consistency in assembled products.
