Parameter Comparison

Engineering Selection Recommendations

The 026TB32R102B1A1 serves as a direct functional substitute for the obsolete 450D102F8 based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters align precisely: 1k Ohm resistance, ±20% tolerance, linear taper, single gang, single turn, and 300° rotation. The substitute component's 5W power rating exceeds the original 0.5W specification, providing enhanced thermal margin and operational headroom in circuit applications.

Mechanical Compatibility: Panel mount configuration, solder lug termination, 3/8-32 bushing thread, and actuator dimensions (1.000" length, 0.250" diameter) are identical. Body diameter variation (0.937" versus 0.938") is within manufacturing tolerance and does not affect mechanical fit or panel mounting.

Product Status and Compliance: The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. The 026TB32R102B1A1 is ROHS3 compliant and REACH unaffected, addressing modern regulatory requirements that the obsolete 450D102F8 does not satisfy.

Material Consideration: The substitute employs wirewound resistive material compared to the original carbon construction. This material change results in improved power handling capability and thermal stability while maintaining the specified electrical performance and tolerance.

Frequently Asked Questions (FAQ)

Q: Can the 026TB32R102B1A1 directly replace the 450D102F8 in existing designs?

A: Yes. The substitute part maintains all critical electrical parameters (1k Ohm, ±20% tolerance, linear taper, 300° rotation) and mechanical specifications (panel mount, solder lug, 3/8-32 bushing, identical actuator dimensions). The higher power rating (5W versus 0.5W) and wirewound construction provide enhanced performance without compromising compatibility.

Q: What is the significance of the power rating difference?

A: The substitute's 5W rating exceeds the original 0.5W specification. This provides additional thermal capacity and operational margin. Applications requiring the original 0.5W rating will operate within the substitute's capability range without thermal stress.

Q: Are there differences in actuator design between these parts?

A: The original 450D102F8 features a flatted actuator type, while the 026TB32R102B1A1 uses a round actuator. Both maintain identical length (1.000") and diameter (0.250") specifications. Actuator type differences do not affect electrical function or mechanical mounting compatibility.

Q: What is the impact of the resistive material change from carbon to wirewound?

A: Wirewound construction provides superior frequency response, lower noise characteristics, and improved temperature stability compared to carbon film. The material change maintains the specified 1k Ohm resistance and ±20% tolerance while delivering enhanced reliability and performance.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The 026TB32R102B1A1 is ROHS3 compliant and REACH unaffected. The original 450D102F8 is RoHS non-compliant, making the substitute necessary for applications subject to modern environmental and regulatory standards.

Q: Are there packaging differences between these components?

A: The original part is listed with packaging designation "-" while the substitute is supplied in Bulk packaging. This reflects the active status and current distribution practices for the 026TB32R102B1A1.

Q: What is the body size tolerance between these parts?

A: The original body diameter is 0.938" (23.83mm) and the substitute is 0.937" (23.80mm). This 0.001" difference is within standard manufacturing tolerance and does not affect panel mounting or mechanical fit.
