Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3339P-1-102 are classified based on electrical and mechanical parameter alignment:

Direct Substitute (Same Series, Enhanced Compliance): The 3339P-1-102LF maintains identical electrical specifications (1 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C, 4-turn, cermet, PC pins) and mechanical dimensions (0.300" diameter). The primary distinction is RoHS3 compliance status, making this variant suitable for applications requiring enhanced environmental compliance while preserving all functional characteristics.

Similar Substitute (Alternative Series, Dimensional Tolerance): The PV12P102A01B00 represents an alternative series offering equivalent electrical performance (1 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C, 4-turn, cermet, PC pins) with minor dimensional variation (0.299" diameter vs. 0.300" diameter). This component operates within acceptable mechanical tolerances for standard through-hole PCB applications. Packaging differs (Bulk vs. Tube), and RoHS3 compliance is confirmed.

Parameter Comparison

Engineering Selection Recommendations

3339P-1-102LF Selection Criteria: Choose this direct substitute when RoHS3 compliance is required for the application or end-market. Electrical and mechanical specifications are identical to the original 3339P-1-102. Both components remain REACH Affected. Tube packaging is maintained. This variant is preferred for new designs or applications with environmental compliance mandates.

PV12P102A01B00 Selection Criteria: Select this alternative when RoHS3 compliance and REACH Unaffected status are both required. The 0.001" (0.02mm) diameter reduction falls within standard PCB through-hole tolerances and does not impact functional performance. Bulk packaging may be advantageous for high-volume procurement. This component represents the most compliant option across both RoHS and REACH frameworks.

Original 3339P-1-102 Retention: Maintain the original part number only when RoHS non-compliance is acceptable for the application and existing inventory or supply chain commitments justify continued use.

Frequently Asked Questions (FAQ)

Q: Can 3339P-1-102LF be used as a direct replacement for 3339P-1-102? A: Yes. Both components share identical electrical specifications (1 kOhm, 0.5W, ±10%, ±100ppm/°C, 4-turn) and mechanical dimensions (0.300" diameter). The primary difference is RoHS3 compliance status. Functional performance in the circuit is equivalent.

Q: What is the significance of the 0.001" diameter difference between 3339P-1-102 and PV12P102A01B00? A: The dimensional variance (0.300" vs. 0.299") is within standard PCB through-hole manufacturing tolerances and does not affect mechanical fit or electrical performance. Both components are mechanically compatible with standard 0.032" diameter PCB holes.

Q: Does packaging type affect component performance? A: No. Tube and Bulk packaging are logistics and handling formats only. Electrical and mechanical performance remains identical. Packaging selection depends on procurement volume and inventory management requirements.

Q: Are there compliance differences between the three parts? A: Yes. The 3339P-1-102 is RoHS non-compliant and REACH Affected. The 3339P-1-102LF is RoHS3 Compliant and REACH Affected. The PV12P102A01B00 is RoHS3 Compliant and REACH Unaffected. Select based on application compliance requirements.

Q: Can PV12P102A01B00 be used in applications originally designed for 3339P-1-102? A: Yes. Electrical specifications are identical. Mechanical dimensions are within acceptable tolerances. Both are Active status components. Compliance status differs; select based on regulatory requirements.
