Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3296W-1-504R are qualified based on 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: 25 (exact match required)
• Adjustment type: Top Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)

The identified substitutes belong to the Bourns PV36 series and maintain all electrical and mechanical parameters identical to the main part. Packaging format differences (Tape & Reel versus Tube) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—3296W-1-504R, PV36W504C01B00, and PV36Y504C01B00—are active products from Bourns Inc. with identical electrical and mechanical specifications. The primary differentiation factors are:

RoHS Compliance: The PV36W504C01B00 and PV36Y504C01B00 are ROHS3 compliant, while the 3296W-1-504R is RoHS non-compliant. Applications subject to RoHS regulatory requirements must use PV36W504C01B00 or PV36Y504C01B00.

Packaging Format: The 3296W-1-504R is supplied in Tape & Reel format, while both PV36 variants are supplied in Tube packaging. Packaging selection depends on assembly process requirements and volume handling.

Physical Dimensions: Minor dimensional variations exist (9.53mm x 4.83mm versus 9.60mm x 5.00mm face dimensions). These differences are within typical manufacturing tolerances and do not affect PCB layout compatibility for standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can PV36W504C01B00 or PV36Y504C01B00 directly replace 3296W-1-504R in existing designs?

A: Yes. All electrical parameters (resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, and resistive material) are identical. Termination style and mounting type are identical. Minor face dimension differences do not affect functional compatibility in standard through-hole PCB applications.

Q: What is the difference between PV36W504C01B00 and PV36Y504C01B00?

A: Both parts are electrically and mechanically identical. The difference is in the base product number designation (PV36W versus PV36Y). Both are ROHS3 compliant and supplied in Tube packaging. Selection between these two should be based on availability and supplier preference.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Tube packaging formats do not affect electrical performance or functional characteristics. Packaging selection is determined by assembly process requirements and component handling procedures.

Q: Are there compliance considerations when selecting a substitute?

A: Yes. If RoHS compliance is required, PV36W504C01B00 or PV36Y504C01B00 must be used, as these are ROHS3 compliant. The 3296W-1-504R is RoHS non-compliant and is unsuitable for applications with RoHS regulatory requirements.

Q: What parameters must match for functional substitution?

A: Resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, and termination style must all match. All identified substitutes meet these criteria.
