Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT-6EV501 are qualified based on strict electrical and functional equivalence across the following parameters:

• Resistance value: 500 Ohms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• RoHS3 compliance status

All identified substitutes meet these core electrical and mechanical requirements. Physical dimensions vary within acceptable ranges for through-hole PCB mounting applications. Packaging format differences (Bulk vs. Tube) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active production components with RoHS3 compliance status matching the CT-6EV501. Selection among equivalent parts should be based on:

Packaging availability: The CT-6EV501 and 72PR500LF are supplied in Bulk packaging. The 3362F-1-501LF, 3329H-1-501LF, and T73YE501KT20 are supplied in Tube packaging. Bulk packaging is suitable for high-volume manufacturing; Tube packaging is appropriate for lower-volume or kit-based applications.

Physical form factor: Dimensional variations exist across the substitute group. The CT-6EV501 (7.00mm x 7.00mm square), 3362F-1-501LF (6.99mm x 6.60mm rectangular), and T73YE501KT20 (7.00mm x 6.60mm rectangular) occupy similar PCB footprints. The 3329H-1-501LF and 82PR500LF (6.35mm diameter round) are more compact. The 72PR500LF (9.53mm x 9.53mm square) requires larger board space.

Regulatory status: The CT-6EV501 and 72PR500LF are REACH Unaffected. The 3362F-1-501LF, 3329H-1-501LF, and 82PR500LF are REACH Affected. The T73YE501KT20 status is not specified in available data. Applications subject to REACH restrictions should confirm regulatory compliance with the selected substitute.

Moisture sensitivity: The CT-6EV501 and T73YE501KT20 have MSL 1 (Unlimited). Other substitutes have MSL Not Applicable, indicating no moisture sensitivity constraints.

Inventory availability: 82PR500LF (5362 pcs), 3329H-1-501LF (2170 pcs), T73YE501KT20 (1669 pcs), 3362F-1-501LF (1370 pcs), and 72PR500LF (1203 pcs) are in stock.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CT-6EV501 with any of the listed parts without circuit redesign?

A: Yes, all listed substitutes meet identical electrical specifications (500 Ohms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn top adjustment, cermet resistive material, through-hole PC pin termination). Physical dimensions vary; verify PCB footprint compatibility before assembly.

Q: What is the primary difference between these substitute parts?

A: The primary differences are physical form factor (square, rectangular, or round), packaging format (Bulk or Tube), and regulatory compliance status (REACH Affected vs. Unaffected). Electrical performance is equivalent across all parts.

Q: Does packaging format affect part performance?

A: No. Bulk and Tube packaging formats do not affect electrical or functional performance. Packaging selection is based on manufacturing process requirements and inventory management practices.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant, matching the CT-6EV501 compliance status.

Q: Which substitute has the smallest physical footprint?

A: The 3329H-1-501LF and 82PR500LF both feature a 0.250" diameter (6.35mm) round form factor, providing the most compact mounting profile.

Q: Which substitute has the largest physical footprint?

A: The 72PR500LF features a 0.375" x 0.375" (9.53mm x 9.53mm) square form factor, requiring the largest PCB space allocation.

Q: Are there REACH compliance considerations for substitute selection?

A: Yes. The CT-6EV501 and 72PR500LF are REACH Unaffected. The 3362F-1-501LF, 3329H-1-501LF, and 82PR500LF are REACH Affected. Applications subject to REACH restrictions should confirm regulatory compliance with the selected substitute before procurement.
