PVG5H205A01R00 Equivalent & Substitute Parts

Part Overview

The PVG5H205A01R00 is a 2 MOhm, 0.25W surface mount trimmer potentiometer manufactured by Bourns Inc. in the PVG5 series. This component features cermet resistive material, J lead termination, and side adjustment with 11 turns. The part is classified as obsolete, making identification of suitable alternatives necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (2 MOhms), power rating (0.25W), tolerance (±10%), resistive material (cermet), mounting type (surface mount), termination style (J lead), and adjustment type (side adjustment). Parts meeting all these criteria are classified as direct substitutes. Parts with identical electrical specifications but different adjustment types (top vs. side) are classified as direct alternatives with mechanical considerations. Parts from alternative manufacturers meeting identical electrical and mechanical specifications are classified as similar substitutes.

Engineering Selection Recommendations

PVG5H205C03R00 is the primary active substitute from Bourns Inc., maintaining identical electrical specifications, turn count, adjustment type, and face dimensions as the original PVG5H205A01R00. This part is available in Tape & Reel packaging and carries ROHS3 compliance with active product status.

3224J-1-205E is an active Bourns alternative with identical electrical parameters and temperature coefficient. The 12-turn configuration and slightly reduced face dimensions (4.60 x 4.60mm versus 4.80 x 3.70mm) require mechanical validation for PCB layout compatibility.

PVG5A205C03R00 maintains electrical equivalence but features top adjustment instead of side adjustment. This configuration change requires mechanical redesign of the adjustment access point on the PCB and is suitable only when top-mounted adjustment is acceptable.

SM-42A205 and SM-42TA205 from Nidec Components Corporation provide electrical equivalence with identical temperature coefficient and turn count. The larger face dimension (4.80 x 4.60mm) requires PCB layout verification. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can PVG5H205C03R00 directly replace PVG5H205A01R00 without PCB modification?

A: Yes. Both parts share identical resistance, power rating, tolerance, turn count, adjustment type, and face dimensions. The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. bulk).

Q: What is the significance of the temperature coefficient difference between ±100ppm/°C and ±150ppm/°C?

A: Temperature coefficient defines resistance drift over operating temperature range. The ±100ppm/°C specification in PVG5H205A01R00 and 3224J-1-205E provides tighter temperature stability than the ±150ppm/°C specification in PVG5A205C03R00 and PVG5H205C03R00. Selection depends on circuit temperature stability requirements.

Q: Are the Nidec SM-42 series parts mechanically compatible?

A: SM-42A205 and SM-42TA205 have larger face dimensions (4.80 x 4.60mm) compared to the original (4.80 x 3.70mm). PCB layout must accommodate the increased height. Both parts maintain electrical equivalence and are available in active status.

Q: What is the difference between 3224J-1-205E and PVG5H205C03R00?

A: Both are active Bourns alternatives. 3224J-1-205E features 12 turns with slightly smaller face dimensions (4.60 x 4.60mm). PVG5H205C03R00 maintains the original 11-turn configuration and face dimensions (4.80 x 3.70mm). Selection depends on available PCB space and adjustment resolution requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and bulk packaging formats do not affect component electrical characteristics. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed alternatives maintain ROHS3 compliance status, consistent with the original PVG5H205A01R00 specification.
