Key Parameters

Substitute Part Grouping Explanation

Substitution of the SP28W1G10 is based on strict equivalence across the following critical parameters:

• Contact type, size, and termination method (Pin, Size 20, Crimp)
• Wire gauge compatibility (28-30 AWG / 0.05 ~ 0.08 mm²)
• Contact material and finish specifications (Copper Alloy, Gold plating)
• Series compatibility (ecomate® Aquarius™)
• Regulatory compliance (RoHS3, REACH)
• Moisture sensitivity level (MSL 1)

The substitute SP28W2G10 maintains identical electrical and mechanical specifications while differing only in packaging format and product status. This substitution is valid for direct replacement in applications where the SP28W1G10 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The SP28W2G10 is the direct substitute for the obsolete SP28W1G10. Both parts are manufactured by Amphenol Sine Systems Corp within the ecomate® Aquarius™ series and maintain identical electrical and mechanical specifications. The SP28W2G10 is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH requirements, making them suitable for applications subject to environmental regulations. The MSL 1 rating indicates unlimited shelf life under standard storage conditions.

The primary difference between the two parts is packaging format: SP28W1G10 uses standard packaging while SP28W2G10 is supplied in Tape & Reel (TR) format. This packaging difference does not affect component performance or compatibility and is determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can SP28W2G10 be used as a direct replacement for SP28W1G10?

A: Yes. Both parts are electrically and mechanically identical, with identical contact specifications, wire gauge ratings, termination methods, and material compositions. The only difference is packaging format.

Q: What is the significance of the packaging difference between these parts?

A: SP28W1G10 uses standard packaging while SP28W2G10 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated assembly processes, while standard packaging is typically used for manual assembly or lower-volume applications. The component itself is unchanged.

Q: Why is SP28W1G10 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. SP28W2G10 serves as the active production equivalent and should be specified for new designs and ongoing procurement.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH status, and MSL ratings. They are equivalent from a regulatory and environmental standpoint.

Q: What wire gauges are compatible with these contacts?

A: Both parts are rated for 28-30 AWG wire (0.05 ~ 0.08 mm² metric equivalent). Wire gauge compatibility is a critical substitution criterion and must not be exceeded.

Q: Is the gold plating thickness identical between both parts?

A: Yes. Both parts feature 10.0 µin (0.25 µm) gold plating on copper alloy contacts, ensuring identical electrical and corrosion resistance properties.
