Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EVJ-C25F02D54 must satisfy the following core electrical and mechanical parameters:

• Resistance value of 50k Ohm with ±20% tolerance
• Logarithmic taper configuration
• 2 Gang potentiometer design
• 1 Turn rotation specification
• 300° rotation angle
• Side Adjustment type
• PC Pins termination
• Power rating sufficient for application requirements

The 91A2A-B28-D18/D18L from Bourns Inc. meets these substitution criteria. While this part features a higher power rating (0.25W vs. 0.05W), panel mount configuration instead of through hole snap-in, and conductive plastic resistive material, it maintains electrical equivalence in resistance, taper, gang configuration, and rotation characteristics. The increased power rating provides additional thermal margin and does not create incompatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The 91A2A-B28-D18/D18L is electrically equivalent to the EVJ-C25F02D54 for applications requiring 50k Ohm 2 Gang Logarithmic potentiometers with 300° rotation and side adjustment. The substitute part is currently in active production status with 1333 units available in inventory, compared to the obsolete EVJ-C25F02D54 with limited remaining stock of 766 units.

The Bourns component carries ROHS3 compliance and REACH Affected status, providing regulatory alignment for modern manufacturing environments. The increased power rating of 0.25W accommodates higher dissipation requirements without electrical incompatibility. The conductive plastic resistive material in the Bourns part offers improved temperature stability with a specified coefficient of ±1000ppm/°C.

Mechanical integration requires evaluation of mounting configuration differences. The EVJ-C25F02D54 uses through-hole snap-in mounting, while the 91A2A-B28-D18/D18L employs panel mount with 3/8-32 bushing thread. PCB layout and mechanical housing modifications may be necessary to accommodate this substitution.

Frequently Asked Questions (FAQ)

Q: Can the 91A2A-B28-D18/D18L directly replace the EVJ-C25F02D54 without circuit modifications?

A: Electrical substitution is valid. The 50k Ohm resistance, logarithmic taper, 2 Gang configuration, and 300° rotation are identical. The higher power rating (0.25W vs. 0.05W) does not create circuit incompatibility. Mechanical integration requires assessment of mounting type differences.

Q: What are the key differences between these two potentiometers?

A: Primary differences include mounting type (through-hole snap-in vs. panel mount), actuator design (flatted vs. slotted), resistive material composition, and power rating. Electrical parameters including resistance, taper, gang count, and rotation angle are equivalent.

Q: Is the conductive plastic material in the Bourns part compatible with the original application?

A: Conductive plastic potentiometers provide stable performance across temperature ranges with specified temperature coefficient of ±1000ppm/°C. Compatibility depends on application-specific environmental and performance requirements.

Q: What inventory considerations apply to this substitution?

A: The EVJ-C25F02D54 is obsolete with 766 units remaining in stock. The 91A2A-B28-D18/D18L is in active production with 1333 units available, providing superior long-term supply chain reliability.

Q: Are there compliance or regulatory differences between these parts?

A: The Bourns 91A2A-B28-D18/D18L carries ROHS3 compliance and REACH Affected status. The Panasonic EVJ-C25F02D54 specifies MSL 1 (Unlimited). Both parts share EAR99 ECCN and 8533.40.8070 HTSUS classification.
