Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76PSB08 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

Electrical Parameters:

• Circuit type: SPST
• Number of positions: 8
• Current rating: 150mA minimum
• Voltage rating: 30VDC minimum

Mechanical Parameters:

• Actuator type: Piano with raised level
• Contact material and finish: Copper alloy with gold plating
• Mounting configuration: Through hole, right angle orientation
• Termination style: PC pin
• Pitch spacing: 0.100" (2.54mm)
• Height above board: 0.301" (7.65mm)

Environmental Parameters:

• Operating temperature range: -40°C to 85°C
• Mechanical and electrical life: 2,000 cycles minimum
• Moisture sensitivity: MSL 1

Only parts meeting all these criteria are classified as direct substitutes. Packaging and product status differences do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB08T is a direct functional equivalent to the 76PSB08. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility in circuit applications.

Product Status Consideration: The 76PSB08 is classified as obsolete, while the 76PSB08T maintains active product status. The 76PSB08T is the current production equivalent and is recommended for new designs and ongoing procurement.

Compliance Consideration: The 76PSB08T achieves RoHS3 compliance, whereas the 76PSB08 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 76PSB08T is the appropriate selection.

Packaging Consideration: The 76PSB08T is supplied in tube packaging, while the 76PSB08 is supplied in bulk. Packaging format does not affect electrical or mechanical performance and is determined by procurement and inventory requirements.

Both parts share identical REACH status (REACH Unaffected) and ECCN/HTSUS classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB08T replace the 76PSB08 in existing circuit boards?

A: Yes. The 76PSB08T is a direct substitute with identical electrical ratings (150mA, 30VDC, SPST 8-position), actuator type (piano, raised), contact material (gold-plated copper alloy), and mechanical dimensions (0.301" height, 0.100" pitch, through-hole right-angle mounting). Pin-for-pin compatibility is confirmed.

Q: What is the difference between the 76PSB08 and 76PSB08T?

A: The primary differences are product status and compliance. The 76PSB08 is obsolete and RoHS non-compliant. The 76PSB08T is an active product that meets RoHS3 requirements. Packaging differs (bulk versus tube), but all functional parameters are identical.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical current rating (150mA), voltage rating (30VDC), operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), and electrical life (2,000 cycles).

Q: Which part should be used for new designs?

A: The 76PSB08T is the appropriate selection for new designs. It maintains active product status and meets current RoHS3 compliance requirements.

Q: Does packaging affect compatibility?

A: No. The 76PSB08T is supplied in tube packaging while the 76PSB08 is supplied in bulk. Packaging format is a logistics consideration and does not affect electrical or mechanical performance.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C.

Q: What is the pitch spacing for these DIP switches?

A: Both parts have a pitch spacing of 0.100" (2.54mm), which is the standard full pitch for DIP switch configurations.
