Substitute Part Grouping Explanation

The Bourns 91A1A-B24-B13L qualifies as a direct substitute based on complete electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

• Resistance value: 5k Ohm (identical)
• Power rating: 1W (identical)
• Taper: Linear (identical)
• Number of gangs: 1 (identical)
• Resistive material: Conductive Plastic (identical)
• Termination style: PC Pins (identical)
• Mounting type: Panel Mount (identical)
• Rotation angle: 300° (identical)
• Temperature coefficient: ±1000ppm/°C (identical)
• Tolerance: ±20% (identical)
• Physical dimensions and bushing specifications (identical)
• Adjustment type: Side Adjustment (identical)

The substitute part differs only in product status (Active vs. Obsolete), packaging format (Bulk vs. standard), and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 91A1A-B24-B13L is the appropriate selection for new designs and ongoing production applications. The substitute part provides:

• Full electrical and mechanical compatibility with the obsolete 91A1A-B24-B13
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance, meeting current regulatory requirements for restricted substances
• REACH compliance status, supporting international environmental and safety standards

For applications where RoHS non-compliance is not a constraint and existing inventory of the 91A1A-B24-B13 remains available, the original part may continue to be used until depletion. However, for new production and long-term applications, transition to the 91A1A-B24-B13L is recommended.

Frequently Asked Questions (FAQ)

Q: Are the 91A1A-B24-B13 and 91A1A-B24-B13L electrically identical?

A: Yes. Both parts have identical resistance values (5k Ohm), power ratings (1W), temperature coefficients (±1000ppm/°C), tolerances (±20%), and taper characteristics (Linear). They are electrically interchangeable.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts share identical physical dimensions, bushing thread specifications (3/8-32), actuator dimensions (0.750" length, 0.250" diameter), and panel mount configuration. Direct mechanical substitution is possible without PCB or enclosure modifications.

Q: What is the primary difference between these parts?

A: The 91A1A-B24-B13L is the active production variant with ROHS3 compliance and REACH compliance status. The 91A1A-B24-B13 is obsolete and RoHS non-compliant. Both parts are functionally equivalent.

Q: Can I use the 91A1A-B24-B13L as a drop-in replacement?

A: Yes. The substitute part is a direct drop-in replacement with no design modifications required. Electrical performance, mechanical fit, and termination style are identical.

Q: Does packaging format affect compatibility?

A: No. The packaging difference (Bulk vs. standard) does not affect electrical or mechanical performance. Packaging format is a supply chain consideration only.

Q: Are there any compliance considerations for my application?

A: If your application or market requires RoHS or REACH compliance, the 91A1A-B24-B13L is the appropriate choice. The original 91A1A-B24-B13 does not meet these standards.
