Substitute Part Grouping Explanation

The 59630-4-T-05-F has one manufacturer-recommended substitute within the Littelfuse 59630 series. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Output Configuration: SPST-NC
• Float Type: Single Float
• Switching Current Rating: 500 mA
• Voltage Rating: 200VDC
• Switch Actuation Level: 0.2" (5.08 mm)
• Mounting Type: Panel Mount, M8 Thread
• Operating Temperature Range: -40°C to 105°C
• RoHS Compliance Status: ROHS3 Compliant

The substitute part maintains identical electrical and mechanical specifications, with the primary distinction being product status transition from obsolete to active availability.

Parameter Comparison

Engineering Selection Recommendations

The 59630-4-T-02-F is the direct manufacturer-recommended substitute for the obsolete 59630-4-T-05-F. Both components are ROHS3 compliant and maintain identical electrical and mechanical specifications. The substitute part is currently in active production status with confirmed inventory availability (1293 pcs), whereas the original part is obsolete with limited remaining stock (949 pcs).

For new designs and system replacements, the 59630-4-T-02-F should be specified. For legacy system maintenance where original part number documentation is required, cross-reference documentation should be updated to reflect the active equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 59630-4-T-02-F be used as a direct replacement for the 59630-4-T-05-F?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including output configuration, current rating, voltage rating, actuation level, mounting type, and operating temperature range. The substitute is the manufacturer-recommended equivalent.

Q: What is the primary difference between these two part numbers?

A: The 59630-4-T-05-F is classified as obsolete, while the 59630-4-T-02-F is in active production. Both maintain identical functional specifications and compliance certifications.

Q: Are there any packaging differences between the two parts?

A: The 59630-4-T-05-F packaging is listed as unspecified in available documentation. The 59630-4-T-02-F is supplied in box packaging. Verify packaging requirements for your specific application and procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 59630-4-T-05-F and 59630-4-T-02-F are ROHS3 compliant with MSL rating of 1 (Unlimited). The substitute part additionally carries REACH Unaffected status.

Q: What is the switch actuation level, and is it identical between both parts?

A: The switch actuation level is 0.2 inches (5.08 mm) for both parts. This parameter defines the liquid level displacement required to trigger the switch state change.

Q: Are there any temperature or voltage derating considerations?

A: Both parts operate across -40°C to 105°C and are rated for 200VDC at 500 mA. No derating information is provided in the component specifications.
