PVC6A504A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6A504A01B00 is a 500 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. as part of the PVC6 series. This component features ceramic resistive material, PC pin termination, and top adjustment capability with a single turn. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6A504A01B00 is determined by strict alignment across the following critical parameters:

• Resistance value: 500 kOhms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

Two substitute parts meet these criteria:

Direct Substitute: 3362P-1-504LF (Bourns Inc., Trimpot® 3362 - Sealed series) — Active product status with enhanced compliance profile.

Similar Substitute: 72PR500KLF (TT Electronics/BI, 72 series) — Active product status with alternative form factor.

Parameter Comparison

Engineering Selection Recommendations

3362P-1-504LF is the primary substitute for the PVC6A504A01B00. Both components are manufactured by Bourns Inc. and share identical electrical specifications. The 3362P-1-504LF carries Active product status and achieves ROHS3 compliance, making it suitable for new designs and systems requiring modern regulatory alignment. The resistive material differs (Cermet vs. Ceramic), but both materials satisfy the specified electrical parameters. Face dimensions are comparable within typical PCB layout tolerances. This part is available in high inventory (65,600 pcs).

72PR500KLF is a secondary substitute manufactured by TT Electronics/BI. All electrical parameters match the original component exactly. The 72PR500KLF maintains Active product status and ROHS3 compliance. The larger form factor (0.375" x 0.375" square vs. 0.272" x 0.272" square) requires verification against available PCB space. This part is available in moderate inventory (1,969 pcs).

Selection between the two substitutes depends on physical space constraints and supply chain requirements. The 3362P-1-504LF is recommended as the first choice due to comparable dimensions and established Bourns manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3362P-1-504LF directly replace the PVC6A504A01B00 without circuit modification?

A: Yes. Both components share identical electrical specifications: 500 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, and single-turn top adjustment. Face dimensions are comparable (0.275" x 0.260" vs. 0.272" x 0.272"), and both use PC pin through-hole termination. PCB layout verification is recommended to confirm mounting hole compatibility.

Q: What is the difference between Ceramic and Cermet resistive materials in these trimmers?

A: Both materials meet the specified electrical parameters for this application. Cermet (ceramic-metal composite) used in the 3362P-1-504LF and 72PR500KLF offers enhanced stability and reliability characteristics. The original PVC6A504A01B00 uses ceramic material. Material substitution does not affect electrical performance within the stated tolerance and temperature coefficient ranges.

Q: Why is the 72PR500KLF larger than the original component?

A: The 72PR500KLF has a larger form factor (0.375" x 0.375" square face vs. 0.272" x 0.272" square face). This is a design characteristic of the TT Electronics/BI 72 series. Verify available PCB space before selecting this substitute. The 3362P-1-504LF maintains closer dimensional compatibility with the original component.

Q: Are there compliance differences between the substitutes?

A: Yes. The 3362P-1-504LF is ROHS3 compliant and REACH Affected. The 72PR500KLF is ROHS3 compliant and REACH Unaffected. The original PVC6A504A01B00 is RoHS non-compliant and REACH Unaffected. Selection should align with system-level compliance requirements.

Q: What inventory levels are available for each substitute?

A: The 3362P-1-504LF has 65,600 pcs in stock (Tube packaging). The 72PR500KLF has 1,969 pcs in stock (Bulk packaging). Supply availability may influence selection for high-volume applications.
