Substitute Part Grouping Explanation

Substitution of the 3213X501M is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters:

• Resistance value: 500 Ohms
• Power rating: 0.125W (1/8W)
• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 Turn

Mechanical Parameters:

• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Surface Mount
• Termination style: J Lead
• Physical dimensions: Square - 0.134" x 0.134" Face (3.40mm x 3.40mm)

Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level 1 (Unlimited)

The ST-32ETA501 manufactured by Nidec Components Corporation meets all specified electrical, mechanical, and compliance requirements and is classified as an active product with current availability.

Parameter Comparison

Engineering Selection Recommendations

The ST-32ETA501 is a direct functional equivalent to the 3213X501M. Both components are ROHS3 compliant and carry identical electrical specifications, mechanical dimensions, and environmental ratings. The primary distinction is product status: the 3213X501M is obsolete, while the ST-32ETA501 is an active product with current manufacturing and distribution support.

Selection of the ST-32ETA501 as a substitute provides continuity of design performance while ensuring ongoing component availability. The active product status of the ST-32ETA501 supports long-term supply chain reliability and reduces obsolescence risk in production environments.

Packaging differences exist between the original part and substitute: the 3213X501M is supplied in standard packaging, while the ST-32ETA501 is available in Tape & Reel (TR) format. This packaging difference does not affect electrical or mechanical compatibility and is a standard industry practice for active products.

Frequently Asked Questions (FAQ)

Q: Can the ST-32ETA501 be used as a direct replacement for the 3213X501M in existing designs?

A: Yes. The ST-32ETA501 meets all electrical, mechanical, and compliance specifications of the 3213X501M. No design modifications are required for substitution.

Q: Are there differences in performance between the 3213X501M and ST-32ETA501?

A: No. Both components share identical resistance values, power ratings, tolerance specifications, temperature coefficients, adjustment mechanisms, resistive materials, mounting types, termination styles, and physical dimensions.

Q: What is the significance of the product status difference?

A: The 3213X501M is classified as obsolete, indicating discontinued manufacturing. The ST-32ETA501 is an active product with current production and distribution. This difference ensures long-term availability and supply chain continuity when using the ST-32ETA501.

Q: Does the Tape & Reel packaging of the ST-32ETA501 affect compatibility?

A: No. Tape & Reel packaging is a standard distribution format for surface mount components and does not affect electrical or mechanical performance. Packaging format is determined by manufacturing and distribution requirements, not component functionality.

Q: Are both components RoHS compliant?

A: Yes. Both the 3213X501M and ST-32ETA501 are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) ratings.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence across resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, physical dimensions, and compliance certifications. All parameters must match exactly between the original and substitute part.
