PVC6D253A01B00 Equivalent & Substitute Parts

Part Overview

The PVC6D253A01B00 is a 25 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Bourns Inc. with ceramic resistive material, top adjustment, and PC pin termination. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6D253A01B00 is determined by strict equivalence across the following critical parameters:

• Resistance value: 25 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: 1.0 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

The 3362R-1-253LF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Minor variations in resistive material composition (ceramic versus cermet) and physical dimensions within tolerance do not preclude functional equivalence in applications where the PVC6D253A01B00 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The 3362R-1-253LF is the qualified substitute for the PVC6D253A01B00. Selection rationale is based on the following factors:

Electrical Equivalence: Both parts maintain identical resistance (25 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and adjustment characteristics (1.0 turn, top adjustment).

Mechanical Compatibility: Both parts feature through-hole mounting with PC pin termination, ensuring direct PCB integration without layout modification.

Product Status: The 3362R-1-253LF is active production status, providing long-term availability and supply chain stability compared to the obsolete PVC6D253A01B00.

Regulatory Compliance: The 3362R-1-253LF achieves ROHS3 compliance and REACH affected status, meeting current environmental and regulatory requirements for new designs and procurement.

Material Composition: The cermet resistive material in the 3362R-1-253LF provides equivalent performance to the ceramic material in the original part across the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 3362R-1-253LF be used as a direct replacement for the PVC6D253A01B00 without circuit modification?

A: Yes. Both parts share identical electrical specifications (25 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and mechanical interfaces (through-hole, PC pins, top adjustment). No circuit or PCB layout changes are required.

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) in the 3362R-1-253LF provides equivalent performance to the ceramic material in the PVC6D253A01B00 across resistance, tolerance, and temperature coefficient specifications.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The PVC6D253A01B00 has a square face (0.272" x 0.272", 6.90mm x 6.90mm), while the 3362R-1-253LF has a rectangular face (0.275" x 0.260", 6.99mm x 6.60mm). These differences fall within standard PCB layout tolerances for through-hole components and do not affect functional compatibility.

Q: What is the packaging difference between these parts?

A: The PVC6D253A01B00 is supplied in standard packaging, while the 3362R-1-253LF is supplied in tube packaging. Both formats are suitable for automated assembly and manual placement.

Q: Does the 3362R-1-253LF meet current environmental compliance standards?

A: Yes. The 3362R-1-253LF is ROHS3 compliant and REACH affected, meeting current regulatory requirements. The PVC6D253A01B00 is RoHS non-compliant and should be phased out in new designs subject to environmental regulations.
