Substitute Part Grouping Explanation

Substitution of the TE Connectivity 416MA503P is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for direct substitution:

• Resistance value: 50 kOhms
• Power rating: 0.2W (1/5W)
• Tolerance: ±25%
• Temperature coefficient: ±250ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Physical dimensions: Rectangular - 0.319" x 0.268" Face (8.10mm x 6.80mm)
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The Bourns Inc. Trimpot® 3306 series parts 3306F-1-503 and 3306P-1-503 satisfy all substitution criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Both Bourns Trimpot® 3306 series parts provide direct functional equivalence to the obsolete TE Connectivity 416MA503P. Selection between 3306F-1-503 and 3306P-1-503 is determined by application-specific requirements and design constraints.

The 3306F-1-503 and 3306P-1-503 are active products with confirmed manufacturing status, ensuring long-term component availability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production applications.

The primary distinction between the two Bourns substitutes relates to their base product designations (3306F versus 3306P), which may reflect internal design variations within the Trimpot® 3306 series. Both parts are electrically and mechanically equivalent to the original TE Connectivity component and satisfy all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 3306F-1-503 and 3306P-1-503 be used interchangeably with the TE Connectivity 416MA503P?

A: Yes. Both Bourns parts satisfy all electrical and mechanical parameters specified for the 416MA503P, including resistance value, power rating, tolerance, temperature coefficient, adjustment type, resistive material, mounting configuration, termination style, and physical dimensions.

Q: What is the primary reason for substituting the 416MA503P?

A: The 416MA503P is classified as obsolete. The Bourns Trimpot® 3306 series parts are active products with current manufacturing support, ensuring component availability for production and field service applications.

Q: Are there compliance differences between the original part and the substitutes?

A: All three parts are ROHS3 compliant. The Bourns substitutes carry REACH unaffected status, while the original TE Connectivity part lists REACH status as vendor undefined. Both Bourns parts satisfy regulatory requirements for new designs.

Q: Do the substitute parts require PCB layout modifications?

A: No. The substitute parts maintain identical physical dimensions (0.319" x 0.268" face, 8.10mm x 6.80mm) and through-hole PC pin termination, allowing direct PCB footprint compatibility without design changes.

Q: What is the difference between the 3306F-1-503 and 3306P-1-503?

A: Both parts are electrically and mechanically identical and satisfy all substitution criteria. The designation difference (3306F versus 3306P) reflects internal Bourns product line categorization within the Trimpot® 3306 series. Selection between them is based on availability and procurement preferences.

Q: Are the temperature coefficient and tolerance specifications identical across all three parts?

A: Yes. All three parts specify ±250ppm/°C temperature coefficient and ±25% tolerance, ensuring equivalent performance across the specified operating temperature range.
