Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPB21RGRA0 is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Circuit configuration (DPDT or equivalent)
• Switch function (On-Mom or equivalent)
• Current rating (0.4VA AC/DC minimum)
• Voltage rating (20V AC/DC minimum)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole, Right Angle)
• Actuator type (Round, Plunger)
• Termination style (PC Pin)

Environmental and Operational Parameters:

• Operating temperature range (-30°C ~ 65°C)
• Electrical life (80,000 Cycles)

Substitute parts must maintain identical or superior performance across all these parameters to ensure functional equivalence within the original application circuit.

Engineering Selection Recommendations

1-1825097-9 (Direct Substitute)

The part number 1-1825097-9 is a direct functional equivalent to TPB21RGRA0. Both components share identical electrical specifications (DPDT, On-Mom, 0.4VA, 20V), mechanical configuration (Through Hole, Right Angle, PC Pin termination), and operational parameters (80,000 cycle electrical life, -30°C to 65°C operating range). The primary distinction is product status: 1-1825097-9 carries Active status with 988 units in stock, whereas TPB21RGRA0 is Obsolete. This substitute provides direct replacement capability without circuit modification.

TPB21MGRA0 (Manufacturer Recommended Alternative)

The TPB21MGRA0 is designated as the manufacturer-recommended alternative. This part differs in circuit configuration (DPST-NO versus DPDT) and switch function (Off-Mom versus On-Mom). These differences represent functional changes that require circuit-level evaluation. TPB21MGRA0 maintains identical voltage, current, mounting, and environmental specifications. This substitute is suitable only when the application circuit can accommodate the reduced pole configuration and altered switch function. TPB21MGRA0 carries Active product status with 928 units in stock.

Frequently Asked Questions (FAQ)

Q: Can 1-1825097-9 replace TPB21RGRA0 without circuit modification?

A: Yes. The 1-1825097-9 maintains identical electrical and mechanical specifications as TPB21RGRA0, including DPDT circuit configuration, On-Mom function, 0.4VA current rating, 20V voltage rating, and PC pin through-hole right-angle mounting. Direct substitution is supported.

Q: What is the key difference between 1-1825097-9 and TPB21MGRA0?

A: The 1-1825097-9 preserves the DPDT circuit configuration and On-Mom function of the original TPB21RGRA0. The TPB21MGRA0 changes the circuit to DPST-NO and the function to Off-Mom. Circuit modification is required to use TPB21MGRA0 as a replacement.

Q: Why is TPB21RGRA0 listed as Obsolete?

A: TPB21RGRA0 carries Obsolete product status, indicating it is no longer manufactured or supported by TE Connectivity ALCOSWITCH Switches. The 1-1825097-9 and TPB21MGRA0 are Active alternatives available for new designs and ongoing production.

Q: Are there packaging differences between these substitutes?

A: TPB21RGRA0 and 1-1825097-9 do not specify packaging details in the provided data. TPB21MGRA0 is packaged in Bulk. Packaging specifications should be confirmed with the supplier for procurement requirements.

Q: Do all three parts meet the same environmental and compliance standards?

A: All three parts operate within the -30°C to 65°C temperature range and support 80,000 electrical cycles. All carry EAR99 ECCN classification and 8536.50.9031 HTSUS code. RoHS status is Not Applicable for all three components.

Q: What inventory levels are available for each substitute?

A: TPB21RGRA0 has 725 units in stock (Obsolete status). The 1-1825097-9 substitute has 988 units in stock (Active status). The TPB21MGRA0 alternative has 928 units in stock (Active status).
