Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1623853-4 are qualified based on electrical and mechanical parameter equivalence. The following parameters must match for direct substitution:

• Resistance value: 10 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±20%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins

The Bourns Inc. PV32 series parts (PV32H103A01B00 and PV32P103A01B00) satisfy all electrical parameter requirements. Physical form factor differences exist (round 6.60mm diameter versus square 6.40mm), which may require mechanical evaluation for specific PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both Bourns PV32 series alternatives (PV32H103A01B00 and PV32P103A01B00) are active products with ROHS3 compliance, providing regulatory advantage over the obsolete TE Connectivity 1623853-4. All three parts share identical electrical specifications and cermet construction.

Selection between the two Bourns alternatives depends on internal design designation requirements, as both parts are electrically and mechanically equivalent. The PV32H103A01B00 and PV32P103A01B00 differ only in base product number designation (PV32H versus PV32P), with no impact on functional performance.

Physical form factor transition from square (6.40mm) to round (6.60mm) geometry requires PCB layout verification to confirm mounting hole compatibility and clearance adequacy.

Frequently Asked Questions (FAQ)

Q: Can PV32H103A01B00 and PV32P103A01B00 be used interchangeably?

A: Yes. Both parts are electrically identical with matching resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics. Selection between them depends on design documentation requirements and internal part numbering systems.

Q: What is the primary difference between the TE Connectivity 1623853-4 and Bourns substitutes?

A: The TE Connectivity part is obsolete, while both Bourns alternatives are active products with ROHS3 compliance. Electrical performance is equivalent. Physical form factor differs: TE Connectivity uses square geometry (6.40mm x 6.40mm), while Bourns parts use round geometry (0.260" diameter / 6.60mm).

Q: Does the form factor change from square to round affect substitution?

A: Form factor change requires mechanical evaluation. PCB mounting hole patterns, clearance zones, and spatial constraints must be assessed for the specific application. Electrical substitution is valid; mechanical integration requires design review.

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

A: Yes. The Bourns alternatives carry ROHS3 compliance certification, while the TE Connectivity part does not specify RoHS status. Both maintain REACH Unaffected status. ROHS3 compliance may be required for new designs or specific market applications.

Q: What parameters must remain constant for direct substitution?

A: Resistance (10 kOhms), power rating (0.5W), tolerance (±20%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top), resistive material (cermet), mounting type (through hole), and termination style (PC pins) must all match for functional equivalence.
