SA3148 Equivalent & Substitute Parts

Part Overview

The SA3148 is a pin contact component manufactured by Bulgin for use in Buccaneer® Mini circular connectors. This crimp-style gold-plated contact is designed for 20-24 AWG wire applications in power distribution circuits. The part maintains active product status with full RoHS3 compliance and has 1003 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component sourcing flexibility across qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SA3148 is determined by the following critical parameters:

• Contact Type: Pin configuration required
• Contact Termination: Crimp attachment method required
• Contact Material & Finish: Copper alloy with gold plating required
• Wire Gauge Compatibility: AWG range must accommodate 20-24 AWG conductors
• Regulatory Compliance: RoHS3 compliance required

The identified substitute M39029/58-362 qualifies based on matching contact type (pin), termination method (crimp), material composition (copper alloy), and finish specification (gold). Wire gauge range overlap (22-26 AWG encompasses the upper portion of the SA3148 range) and equivalent regulatory status support substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SA3148 and M39029/58-362 maintain active product status with full RoHS3 compliance and equivalent export classification (EAR99). Selection between these components should be based on:

• Wire gauge requirements: SA3148 supports 20-24 AWG; M39029/58-362 supports 22-26 AWG. For 20-21 AWG applications, SA3148 is the appropriate selection. For 22-24 AWG applications, both parts are suitable. For 25-26 AWG applications, M39029/58-362 is required.

• Contact finish thickness: M39029/58-362 provides increased gold plating thickness (50.0µin versus 3.94µin), which may be advantageous in high-cycle mating environments or applications requiring enhanced corrosion resistance.

• Series compatibility: SA3148 is specified for Buccaneer® Mini series connectors; M39029/58-362 is specified for MIL-C-39029 military series connectors. Connector housing compatibility must be verified independently.

• Inventory availability: Current stock levels differ between manufacturers and should be evaluated against procurement timelines.

Frequently Asked Questions (FAQ)

Q: Can M39029/58-362 be used as a direct replacement for SA3148 in all applications?

A: M39029/58-362 is suitable for applications using 22-24 AWG wire. For 20-21 AWG applications, SA3148 is the required selection due to wire gauge range limitations of the substitute part.

Q: What is the significance of the contact finish thickness difference?

A: SA3148 has 3.94µin (0.10µm) gold plating; M39029/58-362 has 50.0µin (1.27µm) gold plating. Thicker plating provides extended durability in high-cycle mating applications and enhanced protection against corrosion. Selection depends on application duty cycle and environmental exposure requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SA3148 and M39029/58-362 are RoHS3 compliant and carry equivalent EAR99 export classification.

Q: Can these contacts be used interchangeably in the same connector housing?

A: Contact compatibility with connector housings is determined by contact size, series specification, and mechanical fit. SA3148 is specified for Buccaneer® Mini series; M39029/58-362 is specified for MIL-C-39029 military series. Housing compatibility must be confirmed through connector manufacturer documentation.

Q: What wire gauges are supported by each part?

A: SA3148 supports 20-24 AWG wire. M39029/58-362 supports 22-26 AWG wire. The overlap range is 22-24 AWG, where both parts are functionally equivalent for wire termination.
